3Microsoft Research Video 103385: J Is For JavaScript: A Direct-style Correspondence Between Algol-like Languages And JavaScript Using First-class Continuations
By Microsoft Research
It is a time-honored fashion to implement a domain-specific language (DSL) by translation to a general-purpose language. Such an implementation is more portable, but an unidiomatic translation jeopardizes performance because, in practice, language implementations favor the common cases. This tension arises especially when the domain calls for complex control structures. We illustrate this tension by revisiting Landin's original correspondence between Algol and Church's lambda-notation. We translate domain-specific programs with lexically scoped jumps to JavaScript. Our translation produces the same block structure and binding structure as in the source program, a la Abdali. The target code uses a control operator in direct style, a la Landin. In fact, the control operator used is almost Landin's J---hence our title. Our translation thus complements a continuation-passing translation a la Steele. These two extreme translations require JavaScript implementations to cater either for first-class continuations, as Rhino does, or for proper tail recursion. Less extreme translations should emit more idiomatic control-flow instructions such as for, break, and throw. The present experiment leads us to conclude that translations should preserve not just the data structures and the block structure of a source program, but also its control structure. We thus identify a new class of use cases for control structures in JavaScript, namely the idiomatic translation of control structures from DSLs. ©2009 Microsoft Corporation. All rights reserved.

13LAC 2014 - Paper: From Faust To Web Audio: Compiling Faust To JavaScript Using Emscripten
By Myles Borins
Linux Audio Conference 2014 Paper: From Faust to Web Audio: Compiling Faust to JavaScript using Emscripten Myles Borins The Web Audio API is a platform for doing audio synthesis in the browser. Currently it has a number of natively compiled audio nodes capable of doing advanced synthesis. One of the available nodes the "JavaScriptNode" allows individuals to create their own custom unit generators in pure JavaScript. The Faust project, developed at Grame CNCM, consists of both a language and a compiler and allows individuals to deploy a signal processor to various languages and platforms. This paper examines a technology stack that allows for Faust to be compiled to highly optimized JavaScript unit generators that synthesize sound using the Web Audio API.

16Beginning Android Web Apps Development : Develop For Android Using HTML5, CSS3, And JavaScript
By Westfall, Jon
Linux Audio Conference 2014 Paper: From Faust to Web Audio: Compiling Faust to JavaScript using Emscripten Myles Borins The Web Audio API is a platform for doing audio synthesis in the browser. Currently it has a number of natively compiled audio nodes capable of doing advanced synthesis. One of the available nodes the "JavaScriptNode" allows individuals to create their own custom unit generators in pure JavaScript. The Faust project, developed at Grame CNCM, consists of both a language and a compiler and allows individuals to deploy a signal processor to various languages and platforms. This paper examines a technology stack that allows for Faust to be compiled to highly optimized JavaScript unit generators that synthesize sound using the Web Audio API.

18OpenJsCad: Like OpenSCAD, But Using JavaScript (16272)
By Joost (joostn)
Not sure how to announce this other than by uploading a 'thing'. So here is one. Enthousiastic about OpenSCAD but somewhat frustrated by the limitations of its language, I've worked on an alternative using Javascript. It's free, completely open source, still seriously under construction, based on Evan Wallace's CSG.js library and can be used in a web browser, See: http://joostn.github.com/OpenJsCad/ The benefits over openSCAD are mainly in the language itself: you can use dynamic arrays for example, and solids can be stored in variables. UPDATE: I've added a parser for local files as well. Create your own .jscad files, go to http://joostn.github.com/OpenJsCad/processfile.html to parse them into an STL file. UPDATE 2: Here's my first real thing designed with OpenJsCad: http://www.thingiverse.com/thing:16329 UPDATE 3: Now with interactive parameter editing! Check out: http://joostn.github.com/OpenJsCad/gearsdemo.html Syntax has been changed slightly! Solids must now be constructed in, and returned from, the main() function. Previously this was done in global scope of the script.

20The Chromium Logo The Chromium Projects Home Chromium ChromiumOS Quick Links Report Bugs Discuss Other Sites Chromium Blog Google Chrome Extensions Except As Otherwise Noted, The Content Of This Page Is Licensed Under A Creative Commons Attribution 2.5 License, And Examples Are Licensed Under The BSD License. Privacy Edit This Page For Developers > How-Tos > Debugging Chromium On Windows First See Get The Code For Checkout And Build Instructions. Getting Started You Can Use Visual Studio's Built-in Debugger Or WinDBG To Debug Chromium. You Don't Need To Use The IDE To Build In Order To Use The Debugger: Autoninja Is Used To Build Chromium And Most Developers Invoke It From A Command Prompt, And Then Open The IDE For Debugging As Necessary. To Start Debugging An Already-built Executable With Visual Studio Just Launch Visual Studio (2019 Or Higher) And Select File-> Open-> Project/Solution (Ctrl+Shift+O) And Select The Executable Of Interest. This Will Create A Solution With That Executable As The 'project'. You Can Then Launch The Debugger With F5 Or F11 Or From The Debug Menu. If You Right-click On The Executable In Solution Explorer And Select Properties Then You Can Edit Things Such As The Executable Path, Command-line Arguments, And Working Directory. You Can Add Additional Executables To The Solution By Using File-> Add-> Existing Project And Selecting Another Already-built Executable. You Can Select Which One To Debug By Right-clicking On One Of Them In Solution Explorer And Selecting Set As Startup Project. When Your Solution File Is Customized To Your Taste You Can Save It To A Directory Such As Out\solutions. Saving It There Helps Ensure That Relative Paths To Source Files, Printed From Build Commands, Will Correctly Identify The Source Files. The Tools Menu Can Be Used To Add Commands To Do Things Like Invoke Autoninja To Build Chrome, Compile The Selected Source File, Or Other Things. Visual Studio 2017 Is Not Recommended For Debugging Of Chromium - Use A Newer Version For Best Performance And Stability. Symbol_level=2 Is The Default On Windows And Gives Full Debugging Information With Types, Locals, Globals, Function Names, And Source/line Information. Symbol_level=1 Creates Smaller PDBs With Just Function Names, And Source/line Information - Source-level Debugging Is Still Supported (new From June 2019), But Local Variables And Type Information Are Missing. Symbol_level=0 Gives Extremely Limited Debugging Abilities, Mostly Just Viewing Call Stacks When Chromium Crashes. Browsing Source Code If You Use A Solution File Generated By Gn (gn Gen --ide=vs) Then Intellisense May Help You Navigate The Code. If This Doesn't Work Or If You Use A Solution Created As Above Then You May Want To Install VsChromium To Help Navigate The Code, As Well As Using Https://source.chromium.org. Profiles It's A Good Idea To Use A Different Chrome Profile For Your Debugging. If You Are Debugging Google Chrome Branded Builds, Or Use A Chromium Build As Your Primary Browser, The Profiles Can Collide So You Can't Run Both At Once, And Your Stable Browser Might See Profile Versions From The Future (Google Chrome And Chromium Use Different Profile Directories By Default So Won't Collide). Use The Command-line Option: --user-data-dir=C:\tmp\my_debug_profile (replace The Path As Necessary) Using The IDE, Go To The Debugging Tab Of The Properties Of The Chrome Project, And Set The Command Arguments. Chrome Debug Log Enable Chrome Debug Logging To A File By Passing --enable-logging --v=1 Command-line Flags At Startup. Debug Builds Place The Chrome_debug.log File In The Out\Debug Directory. Release Builds Place The File In The Top Level Of The User Data Chromium App Directory, Which Is OS-version-dependent. For More Information, See Logging And User Data Directory Details. Symbol Server If You Are Debugging Official Google Chrome Release Builds, Use The Symbol Server: Https://chromium-browser-symsrv.commondatastorage.googleapis.com In Visual Studio, This Goes In Tools > Options Under Debugging > Symbols. You Should Set Up A Local Cache In A Empty Directory On Your Computer. In Windbg You Can Add This To Your Symbol Server Search Path With The Command Below, Where C:\symbols Is A Local Cache Directory: .sympath+ SRV\*C:\symbols\*https://chromium-browser-symsrv.commondatastorage.googleapis.com Alternately, You Can Set The _NT_SYMBOL_PATH Environment Variable To Include Both The Microsoft And Google Symbol Servers - VS, Windbg, And Other Tools Should Both Respect This Environment Variable: _NT_SYMBOL_PATH=SRV\*C:\symbols\*https://msdl.microsoft.com/download/symbols;SRV\*C:\symbols\*https://chromium-browser-symsrv.commondatastorage.googleapis.com Note That Symbol Servers Will Let The Debuggers Download Both The PE Files (DLLs And EXEs) And The PDB Files. Chrome Often Loads Third Party Libraries And Partial Symbols For Some Of These Are Also Public. For Example: AMD: Https://download.amd.com/dir/bin Nvidia: Https://driver-symbols.nvidia.com/ Intel: Https://software.intel.com/sites/downloads/symbols/ For Example, For Completeness, The Following Symbol Server Environment Variable Will Resolve All Of The Above Sources - But This Is More Than Is Normally Needed: _NT_SYMBOL_PATH=SRV\*C:\symbols\*https://msdl.microsoft.com/download/symbols;SRV\*C:\symbols\*https://chromium-browser-symsrv.commondatastorage.googleapis.com;SRV\*C:\symbols\*https://download.amd.com/dir/bin;SRV\*C:\symbols\*https://driver-symbols.nvidia.com/;SRV\*C:\symbols\*https://software.intel.com/sites/downloads/symbols/ Source Indexing You Should Set Up Source Indexing In Your Debugger (.srcfix In Windbg, Tools-> Options-> Debugging-> General-> Enable Source Server Support In Visual Studio) So That The Correct Source Files Will Automatically Be Downloaded Based On Information In The Downloaded Symbols. Additionally, You Must Have Python In Your Path In Order For The Command That Fetches Source Files To Succeed; Launching The Debugger From The Same Environment As Where You Build Chromium Is An Easy Way To Ensure It's Present. This Is Highly Recommended When Debugging Released Google Chrome Builds Or Looking At Crash Dumps. Having The Correct Version Of The Source Files Automatically Show Up Saves Significant Time So You Should Definitely Set This. Multi-process Issues Chromium Can Be Challenging To Debug Because Of Its Multi-process Architecture. When You Select Run In The Debugger, Only The Main Browser Process Will Be Debugged. The Code That Actually Renders Web Pages (the Renderer) And The Plugins Will Be In Separate Processes That's Not (yet!) Being Debugged. The ProcessExplorer Tool Has A Process Tree View Where You Can See How These Processes Are Related. You Can Also Get The Process IDs Associated With Each Tab From The Chrome Task Manager (right-click On An Empty Area Of The Window Title Bar To Open). Automatically Attach To Child Processes There Are Two Visual Studio Extensions That Enable The Debugger To Automatically Attach To All Chrome Processes, So You Can Debug All Of Chrome At Once. Microsoft's Child Process Debugging Power Tool Is A Standalone Extension For This, And VsChromium Is Another Option That Bundles Many Other Additional Features. In Addition To Installing One Of These Extensions, You Must Run Visual Studio As Administrator, Or It Will Silently Fail To Attach To Some Of Chrome's Child Processes. Single-process Mode One Way To Debug Issues Is To Run Chromium In Single-process Mode. This Will Allow You To See The Entire State Of The Program Without Extra Work (although It Will Still Have Many Threads). To Use Single-process Mode, Add The Command-line Flag --single-process This Approach Isn't Perfect Because Some Problems Won't Manifest Themselves In This Mode And Some Features Don't Work And Worker Threads Are Still Spawned Into New Processes. Manually Attaching To A Child Process You Can Attach To The Running Child Processes With The Debugger. Select Tools > Attach To Process And Click The Chrome.exe Process You Want To Attach To. Before Attaching, Make Sure You Have Selected Only Native Code When Attaching To The Process This Is Done By Clicking Select... In The Attach To Process Window And Only Checking Native. If You Forget This, It May Attempt To Attach In "WebKit" Mode To Debug JavaScript, And You'll Get An Error Message "An Operation Is Not Legal In The Current State." You Can Now Debug The Two Processes As If They Were One. When You Are Debugging Multiple Processes, Open The Debug > Windows > Processes Window To Switch Between Them. Sometimes You Are Debugging Something That Only Happens On Startup, And Want To See The Child Process As Soon As It Starts. Use: --renderer-startup-dialog --no-sandbox You Have To Disable The Sandbox Or The Dialog Box Will Be Prohibited From Showing. When The Dialog Appears, Visit Tools > Attach To Process And Attach To The Process Showing The Renderer Startup Dialog. Now You're Debugging In The Renderer And Can Continue Execution By Pressing OK In The Dialog. Startup Dialogs Also Exist For Other Child Process Types: --gpu-startup-dialog, --ppapi-startup-dialog, --utility-startup-dialog, --plugin-startup-dialog (for NPAPI). For Utilities, You Can Add A Service Type --utility-startup-dialog=data_decoder.mojom.DataDecoderService. You Can Also Try The Vs-chromium Plug-in To Attach To The Right Processes. Semi-automatically Attaching The Debugger To Child Processes The Following Flags Cause Child Processes To Wait For 60 Seconds In A Busy Loop For A Debugger To Attach To The Process. Once Either Condition Is True, It Continues On; No Exception Is Thrown. --wait-for-debugger-children[=filter] The Filter, If Provided, Will Fire Only If It Matches The --type Parameter To The Process. Values Include Renderer, Plugin (for NPAPI), Ppapi, Gpu-process, And Utility. When Using This Option, It May Be Helpful To Limit The Number Of Renderer Processes Spawned, Using: --renderer-process-limit=1 Image File Execution Options Using Image File Execution Options (IFEO) Will Not Work Because CreateProcess() Returns The Handle To The Debugger Process Instead Of The Intended Child Process. There Are Also Issues With The Sandbox. Time Travel Debugging You Can Do Time Travel Debugging Using WinDbg Preview (must Be Installed From The Microsoft Store). This Lets You Execute A Program Forward And Backwards. After Capturing A Trace, You Can Set Breakpoints And Step Through Code As Normal, But Also Provides 'backwards' Commands (g-, T-, P-) So That You Can Go Back And Forth Through The Execution. It Is Especially Useful To Set Data Breakpoints (ba Command) And Reverse Continuing, So You Can See When A Certain Variable Was Last Changed To Its Current Value. Chromium Specifics: The Type Of Injection The Time Travel Tracer Needs To Perform Is Incompatible With The Chromium Sandbox. In Order To Record A Trace, You'll Need To Run With --no-sandbox. Chromium Cannot Run Elevated With Administrator Privileges, So The "Launch Executable (advance)" Option Won't Work, You'll Need To Attach After The Process Has Already Launched Via The Checkbox In The Bottom Right. If You Need To Record Startup-like Things, You'll Have To Use --{browser,gpu,renderer,utility}-startup-dialog, Then Attach (and Hope The Relevant Code Hasn't Executed Before That Point). JsDbg -- Data Structure Visualization You Can Install JsDbg As A Plugin For WinDbg Or Visual Studio. It Interactively Lets You Look At Data Structures (such As The DOM Tree, Accessibility Tree, Layout Object Tree, And Others) In A Web Browser As You Debug. See The JsDbg Site For Some Screen Shots And Usage Examples. This Also Works When Examining Memory Dumps (though Not Minidumps), And Also Works Together With Time Travel Debugging. Visual Studio Hints Debug Visualizers Chrome's Custom Debug Visualizers Should Be Added To The Pdb Files And Automatically Picked Up By Visual Studio. The Definitions Are In //tools/win/DebugVisualizers If You Need To Modify Them (the BUILD.gn File There Has Additional Instructions). Don't Step Into Trivial Functions The Debugger Can Be Configured To Automatically Not Step Into Functions Based On Regular Expression. Edit Default.natstepfilter In The Following Directory: For Visual Studio 2015: C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Packages\Debugger\Visualizers (for All Users) Or %USERPROFILE%\My Documents\Visual Studio 2015\Visualizers (for The Current User Only) For Visual Studio 2017 Pro: C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\Packages\Debugger\Visualizers (for All Users) Or %USERPROFILE%\My Documents\Visual Studio 2017\Visualizers (for The Current User Only) Add Regular Expressions Of Functions To Not Step Into. Remember To Regex-escape And XML-escape Them, E.g. < For < And \. For A Literal Dot. Example: Operator New NoStepInto Operator Delete NoStepInto Std::.* NoStepInto WTF::.*Ptr ::.* NoStepInto This File Is Read At Start Of A Debugging Session (F5), So You Don't Need To Restart Visual Studio After Changing It. More Info: Microsoft Email Thread V8 And Chromium V8 Supports Many Command-line Flags That Are Useful For Debugging. V8 Command-line Flags Can Be Set Via The Chromium Command-line Flag --js-flags; For Instance: Chrome.exe --js-flags="--trace_exception --heap_stats" Note That Some V8 Command-line Flags Exist Only In The Debug Build Of V8. For A List Of All V8 Flags Try: Chrome.exe --js-flags="--help" Graphics Debugging GPU Acceleration Of Rendering Can Be More Easily Debugged With Tools. See: Graphics Debugging In Visual Studio 2013 Graphical Debugging With NVIDIA NSight Debugging On Another Machine Sometimes It's Useful To Debug Installation And Execution On A Machine Other Than Your Primary Build Box. To Run The Installer On Said Other Machine, First Build The Mini_installer Target On Your Main Build Machine (e.g., Autoninja -C Out\Debug Mini_installer). Next, On The Debug Machine: Make The Build Machine's Build Volume Available On The Debug Machine Either By Mounting It Locally (e.g., Z:\) Or By Crafting A UNC Path To It (e.g., \\builder\src) Open Up A Command Prompt And Change To A Local Disk Run Src\tools\win\copy-installer.bat In The Remote Checkout By Way Of The Mount (e.g., Z:\PATHTOCHECKOUT\src\...) Or UNC Path (e.g., \\builder\src\...). This Will Copy The Installer, DLLs, And PDBs Into Your Debug Machine's C:\out Or C:\build (depending On If You're Rocking The Component=shared_library Build Or Not) Run C:\out\Debug\mini_installer.exe With The Flags Of Your Choice To Install Chrome. This Can Take Some Time, Especially On A Slow Machine. Watch The Task Manager And Wait Until Mini_installer.exe Exits Before Trying To Launch Chrome (by Way Of The Shortcut(s) Created By The Installer) For Extra Pleasure, Add C:\out\Debug To Your _NT_SYMBOL_PATH Environment Variable Consider Reading The Documentation At The Top Of Copy-installer.bat To See How You Can Run It. It Tries To Be Smart And Copy The Right Things, But You May Need To Be Explicit (e.g., "copy-installer.bat Out Debug"). It Is Safe To Re-run The Script To Copy Only Modified Files (after A Rebuild, For Example). You Can Also Use The Zip Action Of The Isolate Scripts (tools\mb\mb.py) To Package All The Files For A Target Into A Single Zip File, For Example: Python Tools\mb\mb.py Zip Out/Release Base_unittests Base_unittests.zip Finding All Memory Allocations It Is Possible To Use Heap Snapshots To Get Call Stacks On All Outstanding Allocations That Use The OS Heap. This Works Particularly Well If Heap Snapshots Are Started As Soon As The Chrome Browser Process Is Created, But Before It Starts Running. Details Can Be Found In This Batch File. However, With PartitionAlloc Everywhere Most Chromium Allocations No Longer Use The Windows Heap So This Will Only Find A Subset Of Allocations, Mostly From OS DLLs. Find Memory Leaks Note: As With Heap Snapshots The Utility Of UMDH Is Greatly Reduced Now Because PartitionAlloc Everywhere Has Mostly Replaced The Windows Heap. The Windows Heap Manager Has A Really Useful Debug Flag, Where It Can Be Asked To Capture And Store A Stack Trace With Every Allocation. The Tool To Scrape These Stack Traces Out Of Processes Is UMDH, Which Comes With WinDbg. UMDH Is Great. It Will Capture A Snapshot Of The Heap State As Many Times As You Like, And It'll Do It Fairly Quickly. You Then Run It Again Against Either A Single Snapshot, Or A Pair Of Snapshots, At Which Time It'll Symbolize The Stack Traces And Aggregate Usage Up To Unique Stack Traces. Turning On The User Stack Trace Database For Chrome.exe With Gflags.exe Makes It Run Unbearably Slowly; However, Turning On The User Stack Trace Database On For The Browser Alone Is Just Fine. While It's Possible To Turn On The User Stack Database With The "!gflag" Debugging Extension, It's Too Late To Do This By The Time The Initial Debugger Breakpoint Hits. The Only Reasonable Way To Do This Is To Launch GFlags.exe, Enable The User Stack Trace Database (per Image Below), Launch Chrome Under The Debugger. Set A Breakpont When Chrome.dll Loads With "sxe Ld Chrome.dll". Step Up, To Allow Chrome.dll To Initialize. Disable The Stack Trace Database In GFlags.exe. Continue Chrome, Optionally Detaching The Debugger. Image GFlags.exe Settings For User Mode Stack Trace Database. If You Then Ever Suffer A Browser Memory Leak, You Can Snarf A Dump Of The Process With Umdh -p: > Chrome-browser-leak-umdh-dump.txt Which Can Then Typically Be "trivially" Analyzed To Find The Culprit. Miscellaneous Note That By Default Application Verifier Only Works With Non-official Builds Of Chromium. To Use Application Verifier On Official Builds You Need To Add --disable-features=RendererCodeIntegrity To Avoid Sandbox Crashes In Renderer Processes. See Crbug.com/1004989 For Details. See Also This Page. Application Verifier Is A Free Tool From Microsoft (available As Part Of The Windows SDK) That Can Be Used To Flush Out Programming Errors. Starting With M68 Application Verifier Can Be Enabled For Chrome.exe Without Needing To Disable The Sandbox. After Adding Chrome.exe To The List Of Applications To Be Stressed You Need To Expand The List Of Basics Checks And Disable The Leak Checks. You May Also Need To Disable Handles And Locks Checks Depending On Your Graphics Driver And Specific Chrome Version, But The Eventual Goal Is To Have Chrome Run With Handles And Locks Checks Enabled. When Bugs Are Found Chrome Will Trigger A Breakpoint So Running All Chrome Processes Under A Debugger Is Recommended. Chrome Will Run Much More Slowly Because Application Verifier Puts Every Heap Allocation On A Separate Page. Note That With PartitionAlloc Everywhere Most Chromium Allocations Don't Actually Go Through The Windows Heap And Are Therefore Unaffected By Application Verifier. You Can Check The Undocumented 'Cuzz' Checkbox In Application Verifier To Get The Windows Thread Scheduler To Add Some Extra Randomness In Order To Help Expose Race Conditions In Your Code. To Put A Breakpoint On CreateFile(), Add This Break Point: {,,kernel32.dll}_CreateFileW@28 {,,kernel32.dll} Specifies The DLL (context Operator). _ Prefix Means Extern "C". @28 Postfix Means _stdcall With The Stack Pop At The End Of The Function. I.e. The Number Of Arguments In BYTES. You Can Use DebugView From SysInternals Or Sawbuck To View LOG() Messages That Normally Go To Stderr On POSIX.

To start debugging an already-built executable with Visual Studio just launch Visual Studio (2019 or higher) and select File-> Open-> Project/Solution (Ctrl+Shift+O) and select the executable of interest. This will create a solution with that executable as the 'project'. You can then launch the debugger with F5 or F11 or from the Debug menu. If you right-click on the executable in Solution Explorer and select properties then you can edit things such as the executable path, command-line arguments, and working directory. You can add additional executables to the solution by using File-> Add-> Existing Project and selecting another already-built executable. You can select which one to debug by right-clicking on one of them in Solution Explorer and selecting Set as Startup Project. When your solution file is customized to your taste you can save it to a directory such as out\solutions. Saving it there helps ensure that relative paths to source files, printed from build commands, will correctly identify the source files. The Tools menu can be used to add commands to do things like invoke autoninja to build Chrome, compile the selected source file, or other things. Visual Studio 2017 is not recommended for debugging of Chromium - use a newer version for best performance and stability. symbol_level=2 is the default on Windows and gives full debugging information with types, locals, globals, function names, and source/line information. symbol_level=1 creates smaller PDBs with just function names, and source/line information - source-level debugging is still supported (new from June 2019), but local variables and type information are missing. symbol_level=0 gives extremely limited debugging abilities, mostly just viewing call stacks when Chromium crashes. Browsing source code If you use a solution file generated by gn ( gn gen --ide=vs ) then Intellisense may help you navigate the code. If this doesn't work or if you use a solution created as above then you may want to install VsChromium to help navigate the code, as well as using https://source.chromium.org . Profiles It's a good idea to use a different Chrome profile for your debugging. If you are debugging Google Chrome branded builds, or use a Chromium build as your primary browser, the profiles can collide so you can't run both at once, and your stable browser might see profile versions from the future (Google Chrome and Chromium use different profile directories by default so won't collide). Use the command-line option: --user-data-dir =C:\tmp\my_debug_profile (replace the path as necessary) Using the IDE, go to the Debugging tab of the properties of the chrome project, and set the Command Arguments. Chrome debug log Enable Chrome debug logging to a file by passing --enable-logging --v=1 command-line flags at startup. Debug builds place the chrome_debug.log file in the out\Debug directory. Release builds place the file in the top level of the user data Chromium app directory, which is OS-version-dependent. For more information, see logging and user data directory details. Symbol server If you are debugging official Google Chrome release builds, use the symbol server: https://chromium-browser-symsrv.commondatastorage.googleapis.com In Visual Studio, this goes in Tools > Options under Debugging > Symbols . You should set up a local cache in a empty directory on your computer. In windbg you can add this to your symbol server search path with the command below, where C:\symbols is a local cache directory: .sympath+ SRV\*C:\symbols\*https://chromium-browser-symsrv.commondatastorage.googleapis.com Alternately, You can set the _NT_SYMBOL_PATH environment variable to include both the Microsoft and Google symbol servers - VS, windbg, and other tools should both respect this environment variable: _NT_SYMBOL_PATH =SRV\*C:\symbols\*https://msdl.microsoft.com/download/symbols ;SRV\*C:\symbols\*https://chromium-browser-symsrv.commondatastorage.googleapis.com Note that symbol servers will let the debuggers download both the PE files (DLLs and EXEs) and the PDB files. Chrome often loads third party libraries and partial symbols for some of these are also public. For example: AMD : https://download.amd.com/dir/bin Nvidia : https://driver-symbols.nvidia.com/ Intel : https://software.intel.com/sites/downloads/symbols/ For example, for completeness, the following symbol server environment variable will resolve all of the above sources - but this is more than is normally needed: _NT_SYMBOL_PATH=SRV\*C:\symbols\*https://msdl.microsoft.com/download/symbols;SRV\*C:\symbols\*https://chromium-browser-symsrv.commondatastorage.googleapis.com;SRV\*C:\symbols\*https://download.amd.com/dir/bin;SRV\*C:\symbols\*https://driver-symbols.nvidia.com/;SRV\*C:\symbols\*https://software.intel.com/sites/downloads/symbols/ Source indexing You should set up source indexing in your debugger ( .srcfix in windbg, Tools-> Options-> Debugging-> General-> Enable source server support in Visual Studio) so that the correct source files will automatically be downloaded based on information in the downloaded symbols. Additionally, you must have python in your path in order for the command that fetches source files to succeed; launching the debugger from the same environment as where you build Chromium is an easy way to ensure it's present. This is highly recommended when debugging released Google Chrome builds or looking at crash dumps. Having the correct version of the source files automatically show up saves significant time so you should definitely set this. Multi-process issues Chromium can be challenging to debug because of its multi-process architecture . When you select Run in the debugger, only the main browser process will be debugged. The code that actually renders web pages (the Renderer) and the plugins will be in separate processes that's not (yet!) being debugged. The ProcessExplorer tool has a process tree view where you can see how these processes are related. You can also get the process IDs associated with each tab from the Chrome Task Manager (right-click on an empty area of the window title bar to open). Automatically attach to child processes There are two Visual Studio extensions that enable the debugger to automatically attach to all Chrome processes, so you can debug all of Chrome at once. Microsoft's Child Process Debugging Power Tool is a standalone extension for this, and VsChromium is another option that bundles many other additional features. In addition to installing one of these extensions, you must run Visual Studio as Administrator, or it will silently fail to attach to some of Chrome's child processes. Single-process mode One way to debug issues is to run Chromium in single-process mode. This will allow you to see the entire state of the program without extra work (although it will still have many threads). To use single-process mode, add the command-line flag --single-process This approach isn't perfect because some problems won't manifest themselves in this mode and some features don't work and worker threads are still spawned into new processes. Manually attaching to a child process You can attach to the running child processes with the debugger. Select Tools > Attach to Process and click the chrome.exe process you want to attach to. Before attaching, make sure you have selected only Native code when attaching to the process This is done by clicking Select... in the Attach to Process window and only checking Native. If you forget this, it may attempt to attach in "WebKit" mode to debug JavaScript, and you'll get an error message "An operation is not legal in the current state." You can now debug the two processes as if they were one. When you are debugging multiple processes, open the Debug > Windows > Processes window to switch between them. Sometimes you are debugging something that only happens on startup, and want to see the child process as soon as it starts. Use: --renderer-startup-dialog --no-sandbox You have to disable the sandbox or the dialog box will be prohibited from showing. When the dialog appears, visit Tools > Attach to Process and attach to the process showing the Renderer startup dialog. Now you're debugging in the renderer and can continue execution by pressing OK in the dialog. Startup dialogs also exist for other child process types: --gpu-startup-dialog , --ppapi-startup-dialog , --utility-startup-dialog , --plugin-startup-dialog (for NPAPI). For utilities, you can add a service type --utility-startup-dialog=data_decoder.mojom.DataDecoderService . You can also try the vs-chromium plug-in to attach to the right processes. Semi-automatically attaching the debugger to child processes The following flags cause child processes to wait for 60 seconds in a busy loop for a debugger to attach to the process. Once either condition is true, it continues on; no exception is thrown. --wait-for-debugger-children [=filter] The filter, if provided, will fire only if it matches the --type parameter to the process. Values include renderer , plugin (for NPAPI), ppapi , gpu-process , and utility . When using this option, it may be helpful to limit the number of renderer processes spawned, using: --renderer-process-limit = 1 Image File Execution Options Using Image File Execution Options (IFEO) will not work because CreateProcess() returns the handle to the debugger process instead of the intended child process. There are also issues with the sandbox. Time travel debugging You can do time travel debugging using WinDbg Preview (must be installed from the Microsoft Store). This lets you execute a program forward and backwards. After capturing a trace, you can set breakpoints and step through code as normal, but also provides 'backwards' commands (g-, t-, p-) so that you can go back and forth through the execution. It is especially useful to set data breakpoints ( ba command ) and reverse continuing, so you can see when a certain variable was last changed to its current value. Chromium specifics: The type of injection the time travel tracer needs to perform is incompatible with the Chromium sandbox. In order to record a trace, you'll need to run with --no-sandbox . Chromium cannot run elevated with Administrator privileges, so the "Launch executable (advance)" option won't work, you'll need to attach after the process has already launched via the checkbox in the bottom right. If you need to record startup-like things, you'll have to use --{browser,gpu,renderer,utility}-startup-dialog, then attach (and hope the relevant code hasn't executed before that point). JsDbg -- data structure visualization You can install JsDbg as a plugin for WinDbg or Visual Studio . It interactively lets you look at data structures (such as the DOM tree, Accessibility tree, layout object tree, and others) in a web browser as you debug. See the JsDbg site for some screen shots and usage examples. This also works when examining memory dumps (though not minidumps), and also works together with time travel debugging. Visual Studio hints Debug visualizers Chrome's custom debug visualizers should be added to the pdb files and automatically picked up by Visual Studio. The definitions are in //tools/win/DebugVisualizers if you need to modify them (the BUILD.gn file there has additional instructions). Don't step into trivial functions The debugger can be configured to automatically not step into functions based on regular expression. Edit default.natstepfilter in the following directory: For Visual Studio 2015: C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Packages\Debugger\Visualizers (for all users) or %USERPROFILE%\My Documents\Visual Studio 2015\Visualizers (for the current user only) For Visual Studio 2017 Pro: C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\Packages\Debugger\Visualizers (for all users) or %USERPROFILE%\My Documents\Visual Studio 2017\Visualizers (for the current user only) Add regular expressions of functions to not step into. Remember to regex-escape and XML-escape them, e.g. < for < and \. for a literal dot. Example: < Function > < Name > operator new </ Name > < Action > NoStepInto </ Action > </ Function > < Function > < Name > operator delete </ Name > < Action > NoStepInto </ Action > </ Function > <!-- Skip everything in std --> < Function > < Name > std::.* </ Name > < Action > NoStepInto </ Action > </ Function > <!-- all methods on WebKit OwnPtr and variants, ... WTF::*Ptr<*>::* --> < Function > < Name > WTF::.*Ptr<.*>::.* </ Name > < Action > NoStepInto </ Action > </ Function > This file is read at start of a debugging session (F5), so you don't need to restart Visual Studio after changing it. More info: Microsoft email thread V8 and Chromium V8 supports many command-line flags that are useful for debugging. V8 command-line flags can be set via the Chromium command-line flag --js-flags; for instance: chrome.exe --js-flags= "--trace_exception --heap_stats" Note that some V8 command-line flags exist only in the debug build of V8. For a list of all V8 flags try: chrome.exe --js-flags= "--help" Graphics debugging GPU Acceleration of rendering can be more easily debugged with tools. See: Graphics Debugging in Visual Studio 2013 Graphical debugging with NVIDIA NSight Debugging on another machine Sometimes it's useful to debug installation and execution on a machine other than your primary build box. To run the installer on said other machine, first build the mini_installer target on your main build machine (e.g., autoninja -C out\Debug mini_installer). Next, on the debug machine: Make the build machine's build volume available on the debug machine either by mounting it locally (e.g., Z:\) or by crafting a UNC path to it (e.g., \\builder\src) Open up a command prompt and change to a local disk Run src\tools\win\ copy-installer.bat in the remote checkout by way of the mount (e.g., Z:\PATHTOCHECKOUT\src\...) or UNC path (e.g., \\builder\src\...). This will copy the installer, DLLs, and PDBs into your debug machine's C:\out or C:\build (depending on if you're rocking the component=shared_library build or not) Run C:\out\Debug\mini_installer.exe with the flags of your choice to install Chrome. This can take some time, especially on a slow machine. Watch the Task Manager and wait until mini_installer.exe exits before trying to launch Chrome (by way of the shortcut(s) created by the installer) For extra pleasure, add C:\out\Debug to your _NT_SYMBOL_PATH environment variable Consider reading the documentation at the top of copy-installer.bat to see how you can run it. It tries to be smart and copy the right things, but you may need to be explicit (e.g., "copy-installer.bat out Debug"). It is safe to re-run the script to copy only modified files (after a rebuild, for example). You can also use the zip action of the isolate scripts (tools\mb\mb.py) to package all the files for a target into a single zip file, for example: python tools\mb\mb.py zip out/Release base_unittests base_unittests. zip Finding all memory allocations It is possible to use Heap Snapshots to get call stacks on all outstanding allocations that use the OS heap. This works particularly well if heap snapshots are started as soon as the Chrome browser process is created, but before it starts running. Details can be found in this batch file . However, with PartitionAlloc Everywhere most Chromium allocations no longer use the Windows heap so this will only find a subset of allocations, mostly from OS DLLs. Find memory leaks Note: as with Heap Snapshots the utility of UMDH is greatly reduced now because PartitionAlloc Everywhere has mostly replaced the Windows heap. The Windows heap manager has a really useful debug flag, where it can be asked to capture and store a stack trace with every allocation. The tool to scrape these stack traces out of processes is UMDH, which comes with WinDbg . UMDH is great. It will capture a snapshot of the heap state as many times as you like, and it'll do it fairly quickly. You then run it again against either a single snapshot, or a pair of snapshots, at which time it'll symbolize the stack traces and aggregate usage up to unique stack traces. Turning on the user stack trace database for chrome.exe with gflags.exe makes it run unbearably slowly; however, turning on the user stack trace database on for the browser alone is just fine. While it's possible to turn on the user stack database with the "!gflag" debugging extension, it's too late to do this by the time the initial debugger breakpoint hits. The only reasonable way to do this is to Launch GFlags.exe, Enable the user stack trace database (per image below), Launch Chrome under the debugger. Set a breakpont when chrome.dll loads with "sxe ld chrome.dll". Step up, to allow Chrome.dll to initialize. Disable the stack trace database in GFlags.exe. Continue chrome, optionally detaching the debugger. GFlags.exe settings for user mode stack trace database. If you then ever suffer a browser memory leak, you can snarf a dump of the process with umdh - p :<my browser pid> > chrome-browser-leak-umdh-dump.txt which can then typically be "trivially" analyzed to find the culprit. Miscellaneous Note that by default Application Verifier only works with non-official builds of Chromium. To use Application Verifier on official builds you need to add --disable-features=RendererCodeIntegrity to avoid sandbox crashes in renderer processes. See crbug.com/1004989 for details. See also this page . Application Verifier is a free tool from Microsoft (available as part of the Windows SDK) that can be used to flush out programming errors. Starting with M68 Application Verifier can be enabled for chrome.exe without needing to disable the sandbox. After adding chrome.exe to the list of applications to be stressed you need to expand the list of Basics checks and disable the Leak checks. You may also need to disable Handles and Locks checks depending on your graphics driver and specific Chrome version, but the eventual goal is to have Chrome run with Handles and Locks checks enabled. When bugs are found Chrome will trigger a breakpoint so running all Chrome processes under a debugger is recommended. Chrome will run much more slowly because Application Verifier puts every heap allocation on a separate page. Note that with PartitionAlloc Everywhere most Chromium allocations don't actually go through the Windows heap and are therefore unaffected by Application Verifier. You can check the undocumented 'Cuzz' checkbox in Application Verifier to get the Windows thread scheduler to add some extra randomness in order to help expose race conditions in your code. To put a breakpoint on CreateFile(), add this break point: {,,kernel32.dll}_CreateFileW@28 {,,kernel32.dll} specifies the DLL (context operator). _ prefix means extern "C". @28 postfix means _stdcall with the stack pop at the end of the function. i.e. the number of arguments in BYTES. You can use DebugView from SysInternals or sawbuck to view LOG() messages that normally go to stderr on POSIX.

Privacy Edit This Page For Developers > How-Tos > Debugging Chromium On Windows First See Get The Code For Checkout And Build Instructions. Getting Started You Can Use Visual Studio's Built-in Debugger Or WinDBG To Debug Chromium. You Don't Need To Use The IDE To Build In Order To Use The Debugger: Autoninja Is Used To Build Chromium And Most Developers Invoke It From A Command Prompt, And Then Open The IDE For Debugging As Necessary. To Start Debugging An Already-built Executable With Visual Studio Just Launch Visual Studio (2019 Or Higher) And Select File-> Open-> Project/Solution (Ctrl+Shift+O) And Select The Executable Of Interest. This Will Create A Solution With That Executable As The 'project'. You Can Then Launch The Debugger With F5 Or F11 Or From The Debug Menu. If You Right-click On The Executable In Solution Explorer And Select Properties Then You Can Edit Things Such As The Executable Path, Command-line Arguments, And Working Directory. You Can Add Additional Executables To The Solution By Using File-> Add-> Existing Project And Selecting Another Already-built Executable. You Can Select Which One To Debug By Right-clicking On One Of Them In Solution Explorer And Selecting Set As Startup Project. When Your Solution File Is Customized To Your Taste You Can Save It To A Directory Such As Out\solutions. Saving It There Helps Ensure That Relative Paths To Source Files, Printed From Build Commands, Will Correctly Identify The Source Files. The Tools Menu Can Be Used To Add Commands To Do Things Like Invoke Autoninja To Build Chrome, Compile The Selected Source File, Or Other Things. Visual Studio 2017 Is Not Recommended For Debugging Of Chromium - Use A Newer Version For Best Performance And Stability. Symbol_level=2 Is The Default On Windows And Gives Full Debugging Information With Types, Locals, Globals, Function Names, And Source/line Information. Symbol_level=1 Creates Smaller PDBs With Just Function Names, And Source/line Information - Source-level Debugging Is Still Supported (new From June 2019), But Local Variables And Type Information Are Missing. Symbol_level=0 Gives Extremely Limited Debugging Abilities, Mostly Just Viewing Call Stacks When Chromium Crashes. Browsing Source Code If You Use A Solution File Generated By Gn (gn Gen --ide=vs) Then Intellisense May Help You Navigate The Code. If This Doesn't Work Or If You Use A Solution Created As Above Then You May Want To Install VsChromium To Help Navigate The Code, As Well As Using Https://source.chromium.org. Profiles It's A Good Idea To Use A Different Chrome Profile For Your Debugging. If You Are Debugging Google Chrome Branded Builds, Or Use A Chromium Build As Your Primary Browser, The Profiles Can Collide So You Can't Run Both At Once, And Your Stable Browser Might See Profile Versions From The Future (Google Chrome And Chromium Use Different Profile Directories By Default So Won't Collide). Use The Command-line Option: --user-data-dir=C:\tmp\my_debug_profile (replace The Path As Necessary) Using The IDE, Go To The Debugging Tab Of The Properties Of The Chrome Project, And Set The Command Arguments. Chrome Debug Log Enable Chrome Debug Logging To A File By Passing --enable-logging --v=1 Command-line Flags At Startup. Debug Builds Place The Chrome_debug.log File In The Out\Debug Directory. Release Builds Place The File In The Top Level Of The User Data Chromium App Directory, Which Is OS-version-dependent. For More Information, See Logging And User Data Directory Details. Symbol Server If You Are Debugging Official Google Chrome Release Builds, Use The Symbol Server: Https://chromium-browser-symsrv.commondatastorage.googleapis.com In Visual Studio, This Goes In Tools > Options Under Debugging > Symbols. You Should Set Up A Local Cache In A Empty Directory On Your Computer. In Windbg You Can Add This To Your Symbol Server Search Path With The Command Below, Where C:\symbols Is A Local Cache Directory: .sympath+ SRV\*C:\symbols\*https://chromium-browser-symsrv.commondatastorage.googleapis.com Alternately, You Can Set The _NT_SYMBOL_PATH Environment Variable To Include Both The Microsoft And Google Symbol Servers - VS, Windbg, And Other Tools Should Both Respect This Environment Variable: _NT_SYMBOL_PATH=SRV\*C:\symbols\*https://msdl.microsoft.com/download/symbols;SRV\*C:\symbols\*https://chromium-browser-symsrv.commondatastorage.googleapis.com Note That Symbol Servers Will Let The Debuggers Download Both The PE Files (DLLs And EXEs) And The PDB Files. Chrome Often Loads Third Party Libraries And Partial Symbols For Some Of These Are Also Public. For Example: AMD: Https://download.amd.com/dir/bin Nvidia: Https://driver-symbols.nvidia.com/ Intel: Https://software.intel.com/sites/downloads/symbols/ For Example, For Completeness, The Following Symbol Server Environment Variable Will Resolve All Of The Above Sources - But This Is More Than Is Normally Needed: _NT_SYMBOL_PATH=SRV\*C:\symbols\*https://msdl.microsoft.com/download/symbols;SRV\*C:\symbols\*https://chromium-browser-symsrv.commondatastorage.googleapis.com;SRV\*C:\symbols\*https://download.amd.com/dir/bin;SRV\*C:\symbols\*https://driver-symbols.nvidia.com/;SRV\*C:\symbols\*https://software.intel.com/sites/downloads/symbols/ Source Indexing You Should Set Up Source Indexing In Your Debugger (.srcfix In Windbg, Tools-> Options-> Debugging-> General-> Enable Source Server Support In Visual Studio) So That The Correct Source Files Will Automatically Be Downloaded Based On Information In The Downloaded Symbols. Additionally, You Must Have Python In Your Path In Order For The Command That Fetches Source Files To Succeed; Launching The Debugger From The Same Environment As Where You Build Chromium Is An Easy Way To Ensure It's Present. This Is Highly Recommended When Debugging Released Google Chrome Builds Or Looking At Crash Dumps. Having The Correct Version Of The Source Files Automatically Show Up Saves Significant Time So You Should Definitely Set This. Multi-process Issues Chromium Can Be Challenging To Debug Because Of Its Multi-process Architecture. When You Select Run In The Debugger, Only The Main Browser Process Will Be Debugged. The Code That Actually Renders Web Pages (the Renderer) And The Plugins Will Be In Separate Processes That's Not (yet!) Being Debugged. The ProcessExplorer Tool Has A Process Tree View Where You Can See How These Processes Are Related. You Can Also Get The Process IDs Associated With Each Tab From The Chrome Task Manager (right-click On An Empty Area Of The Window Title Bar To Open). Automatically Attach To Child Processes There Are Two Visual Studio Extensions That Enable The Debugger To Automatically Attach To All Chrome Processes, So You Can Debug All Of Chrome At Once. Microsoft's Child Process Debugging Power Tool Is A Standalone Extension For This, And VsChromium Is Another Option That Bundles Many Other Additional Features. In Addition To Installing One Of These Extensions, You Must Run Visual Studio As Administrator, Or It Will Silently Fail To Attach To Some Of Chrome's Child Processes. Single-process Mode One Way To Debug Issues Is To Run Chromium In Single-process Mode. This Will Allow You To See The Entire State Of The Program Without Extra Work (although It Will Still Have Many Threads). To Use Single-process Mode, Add The Command-line Flag --single-process This Approach Isn't Perfect Because Some Problems Won't Manifest Themselves In This Mode And Some Features Don't Work And Worker Threads Are Still Spawned Into New Processes. Manually Attaching To A Child Process You Can Attach To The Running Child Processes With The Debugger. Select Tools > Attach To Process And Click The Chrome.exe Process You Want To Attach To. Before Attaching, Make Sure You Have Selected Only Native Code When Attaching To The Process This Is Done By Clicking Select... In The Attach To Process Window And Only Checking Native. If You Forget This, It May Attempt To Attach In "WebKit" Mode To Debug JavaScript, And You'll Get An Error Message "An Operation Is Not Legal In The Current State." You Can Now Debug The Two Processes As If They Were One. When You Are Debugging Multiple Processes, Open The Debug > Windows > Processes Window To Switch Between Them. Sometimes You Are Debugging Something That Only Happens On Startup, And Want To See The Child Process As Soon As It Starts. Use: --renderer-startup-dialog --no-sandbox You Have To Disable The Sandbox Or The Dialog Box Will Be Prohibited From Showing. When The Dialog Appears, Visit Tools > Attach To Process And Attach To The Process Showing The Renderer Startup Dialog. Now You're Debugging In The Renderer And Can Continue Execution By Pressing OK In The Dialog. Startup Dialogs Also Exist For Other Child Process Types: --gpu-startup-dialog, --ppapi-startup-dialog, --utility-startup-dialog, --plugin-startup-dialog (for NPAPI). For Utilities, You Can Add A Service Type --utility-startup-dialog=data_decoder.mojom.DataDecoderService. You Can Also Try The Vs-chromium Plug-in To Attach To The Right Processes. Semi-automatically Attaching The Debugger To Child Processes The Following Flags Cause Child Processes To Wait For 60 Seconds In A Busy Loop For A Debugger To Attach To The Process. Once Either Condition Is True, It Continues On; No Exception Is Thrown. --wait-for-debugger-children[=filter] The Filter, If Provided, Will Fire Only If It Matches The --type Parameter To The Process. Values Include Renderer, Plugin (for NPAPI), Ppapi, Gpu-process, And Utility. When Using This Option, It May Be Helpful To Limit The Number Of Renderer Processes Spawned, Using: --renderer-process-limit=1 Image File Execution Options Using Image File Execution Options (IFEO) Will Not Work Because CreateProcess() Returns The Handle To The Debugger Process Instead Of The Intended Child Process. There Are Also Issues With The Sandbox. Time Travel Debugging You Can Do Time Travel Debugging Using WinDbg Preview (must Be Installed From The Microsoft Store). This Lets You Execute A Program Forward And Backwards. After Capturing A Trace, You Can Set Breakpoints And Step Through Code As Normal, But Also Provides 'backwards' Commands (g-, T-, P-) So That You Can Go Back And Forth Through The Execution. It Is Especially Useful To Set Data Breakpoints (ba Command) And Reverse Continuing, So You Can See When A Certain Variable Was Last Changed To Its Current Value. Chromium Specifics: The Type Of Injection The Time Travel Tracer Needs To Perform Is Incompatible With The Chromium Sandbox. In Order To Record A Trace, You'll Need To Run With --no-sandbox. Chromium Cannot Run Elevated With Administrator Privileges, So The "Launch Executable (advance)" Option Won't Work, You'll Need To Attach After The Process Has Already Launched Via The Checkbox In The Bottom Right. If You Need To Record Startup-like Things, You'll Have To Use --{browser,gpu,renderer,utility}-startup-dialog, Then Attach (and Hope The Relevant Code Hasn't Executed Before That Point).

- Title: ➤ The Chromium Logo The Chromium Projects Home Chromium ChromiumOS Quick Links Report Bugs Discuss Other Sites Chromium Blog Google Chrome Extensions Except As Otherwise Noted, The Content Of This Page Is Licensed Under A Creative Commons Attribution 2.5 License, And Examples Are Licensed Under The BSD License. Privacy Edit This Page For Developers > How-Tos > Debugging Chromium On Windows First See Get The Code For Checkout And Build Instructions. Getting Started You Can Use Visual Studio's Built-in Debugger Or WinDBG To Debug Chromium. You Don't Need To Use The IDE To Build In Order To Use The Debugger: Autoninja Is Used To Build Chromium And Most Developers Invoke It From A Command Prompt, And Then Open The IDE For Debugging As Necessary. To Start Debugging An Already-built Executable With Visual Studio Just Launch Visual Studio (2019 Or Higher) And Select File-> Open-> Project/Solution (Ctrl+Shift+O) And Select The Executable Of Interest. This Will Create A Solution With That Executable As The 'project'. You Can Then Launch The Debugger With F5 Or F11 Or From The Debug Menu. If You Right-click On The Executable In Solution Explorer And Select Properties Then You Can Edit Things Such As The Executable Path, Command-line Arguments, And Working Directory. You Can Add Additional Executables To The Solution By Using File-> Add-> Existing Project And Selecting Another Already-built Executable. You Can Select Which One To Debug By Right-clicking On One Of Them In Solution Explorer And Selecting Set As Startup Project. When Your Solution File Is Customized To Your Taste You Can Save It To A Directory Such As Out\solutions. Saving It There Helps Ensure That Relative Paths To Source Files, Printed From Build Commands, Will Correctly Identify The Source Files. The Tools Menu Can Be Used To Add Commands To Do Things Like Invoke Autoninja To Build Chrome, Compile The Selected Source File, Or Other Things. Visual Studio 2017 Is Not Recommended For Debugging Of Chromium - Use A Newer Version For Best Performance And Stability. Symbol_level=2 Is The Default On Windows And Gives Full Debugging Information With Types, Locals, Globals, Function Names, And Source/line Information. Symbol_level=1 Creates Smaller PDBs With Just Function Names, And Source/line Information - Source-level Debugging Is Still Supported (new From June 2019), But Local Variables And Type Information Are Missing. Symbol_level=0 Gives Extremely Limited Debugging Abilities, Mostly Just Viewing Call Stacks When Chromium Crashes. Browsing Source Code If You Use A Solution File Generated By Gn (gn Gen --ide=vs) Then Intellisense May Help You Navigate The Code. If This Doesn't Work Or If You Use A Solution Created As Above Then You May Want To Install VsChromium To Help Navigate The Code, As Well As Using Https://source.chromium.org. Profiles It's A Good Idea To Use A Different Chrome Profile For Your Debugging. If You Are Debugging Google Chrome Branded Builds, Or Use A Chromium Build As Your Primary Browser, The Profiles Can Collide So You Can't Run Both At Once, And Your Stable Browser Might See Profile Versions From The Future (Google Chrome And Chromium Use Different Profile Directories By Default So Won't Collide). Use The Command-line Option: --user-data-dir=C:\tmp\my_debug_profile (replace The Path As Necessary) Using The IDE, Go To The Debugging Tab Of The Properties Of The Chrome Project, And Set The Command Arguments. Chrome Debug Log Enable Chrome Debug Logging To A File By Passing --enable-logging --v=1 Command-line Flags At Startup. Debug Builds Place The Chrome_debug.log File In The Out\Debug Directory. Release Builds Place The File In The Top Level Of The User Data Chromium App Directory, Which Is OS-version-dependent. For More Information, See Logging And User Data Directory Details. Symbol Server If You Are Debugging Official Google Chrome Release Builds, Use The Symbol Server: Https://chromium-browser-symsrv.commondatastorage.googleapis.com In Visual Studio, This Goes In Tools > Options Under Debugging > Symbols. You Should Set Up A Local Cache In A Empty Directory On Your Computer. In Windbg You Can Add This To Your Symbol Server Search Path With The Command Below, Where C:\symbols Is A Local Cache Directory: .sympath+ SRV\*C:\symbols\*https://chromium-browser-symsrv.commondatastorage.googleapis.com Alternately, You Can Set The _NT_SYMBOL_PATH Environment Variable To Include Both The Microsoft And Google Symbol Servers - VS, Windbg, And Other Tools Should Both Respect This Environment Variable: _NT_SYMBOL_PATH=SRV\*C:\symbols\*https://msdl.microsoft.com/download/symbols;SRV\*C:\symbols\*https://chromium-browser-symsrv.commondatastorage.googleapis.com Note That Symbol Servers Will Let The Debuggers Download Both The PE Files (DLLs And EXEs) And The PDB Files. Chrome Often Loads Third Party Libraries And Partial Symbols For Some Of These Are Also Public. For Example: AMD: Https://download.amd.com/dir/bin Nvidia: Https://driver-symbols.nvidia.com/ Intel: Https://software.intel.com/sites/downloads/symbols/ For Example, For Completeness, The Following Symbol Server Environment Variable Will Resolve All Of The Above Sources - But This Is More Than Is Normally Needed: _NT_SYMBOL_PATH=SRV\*C:\symbols\*https://msdl.microsoft.com/download/symbols;SRV\*C:\symbols\*https://chromium-browser-symsrv.commondatastorage.googleapis.com;SRV\*C:\symbols\*https://download.amd.com/dir/bin;SRV\*C:\symbols\*https://driver-symbols.nvidia.com/;SRV\*C:\symbols\*https://software.intel.com/sites/downloads/symbols/ Source Indexing You Should Set Up Source Indexing In Your Debugger (.srcfix In Windbg, Tools-> Options-> Debugging-> General-> Enable Source Server Support In Visual Studio) So That The Correct Source Files Will Automatically Be Downloaded Based On Information In The Downloaded Symbols. Additionally, You Must Have Python In Your Path In Order For The Command That Fetches Source Files To Succeed; Launching The Debugger From The Same Environment As Where You Build Chromium Is An Easy Way To Ensure It's Present. This Is Highly Recommended When Debugging Released Google Chrome Builds Or Looking At Crash Dumps. Having The Correct Version Of The Source Files Automatically Show Up Saves Significant Time So You Should Definitely Set This. Multi-process Issues Chromium Can Be Challenging To Debug Because Of Its Multi-process Architecture. When You Select Run In The Debugger, Only The Main Browser Process Will Be Debugged. The Code That Actually Renders Web Pages (the Renderer) And The Plugins Will Be In Separate Processes That's Not (yet!) Being Debugged. The ProcessExplorer Tool Has A Process Tree View Where You Can See How These Processes Are Related. You Can Also Get The Process IDs Associated With Each Tab From The Chrome Task Manager (right-click On An Empty Area Of The Window Title Bar To Open). Automatically Attach To Child Processes There Are Two Visual Studio Extensions That Enable The Debugger To Automatically Attach To All Chrome Processes, So You Can Debug All Of Chrome At Once. Microsoft's Child Process Debugging Power Tool Is A Standalone Extension For This, And VsChromium Is Another Option That Bundles Many Other Additional Features. In Addition To Installing One Of These Extensions, You Must Run Visual Studio As Administrator, Or It Will Silently Fail To Attach To Some Of Chrome's Child Processes. Single-process Mode One Way To Debug Issues Is To Run Chromium In Single-process Mode. This Will Allow You To See The Entire State Of The Program Without Extra Work (although It Will Still Have Many Threads). To Use Single-process Mode, Add The Command-line Flag --single-process This Approach Isn't Perfect Because Some Problems Won't Manifest Themselves In This Mode And Some Features Don't Work And Worker Threads Are Still Spawned Into New Processes. Manually Attaching To A Child Process You Can Attach To The Running Child Processes With The Debugger. Select Tools > Attach To Process And Click The Chrome.exe Process You Want To Attach To. Before Attaching, Make Sure You Have Selected Only Native Code When Attaching To The Process This Is Done By Clicking Select... In The Attach To Process Window And Only Checking Native. If You Forget This, It May Attempt To Attach In "WebKit" Mode To Debug JavaScript, And You'll Get An Error Message "An Operation Is Not Legal In The Current State." You Can Now Debug The Two Processes As If They Were One. When You Are Debugging Multiple Processes, Open The Debug > Windows > Processes Window To Switch Between Them. Sometimes You Are Debugging Something That Only Happens On Startup, And Want To See The Child Process As Soon As It Starts. Use: --renderer-startup-dialog --no-sandbox You Have To Disable The Sandbox Or The Dialog Box Will Be Prohibited From Showing. When The Dialog Appears, Visit Tools > Attach To Process And Attach To The Process Showing The Renderer Startup Dialog. Now You're Debugging In The Renderer And Can Continue Execution By Pressing OK In The Dialog. Startup Dialogs Also Exist For Other Child Process Types: --gpu-startup-dialog, --ppapi-startup-dialog, --utility-startup-dialog, --plugin-startup-dialog (for NPAPI). For Utilities, You Can Add A Service Type --utility-startup-dialog=data_decoder.mojom.DataDecoderService. You Can Also Try The Vs-chromium Plug-in To Attach To The Right Processes. Semi-automatically Attaching The Debugger To Child Processes The Following Flags Cause Child Processes To Wait For 60 Seconds In A Busy Loop For A Debugger To Attach To The Process. Once Either Condition Is True, It Continues On; No Exception Is Thrown. --wait-for-debugger-children[=filter] The Filter, If Provided, Will Fire Only If It Matches The --type Parameter To The Process. Values Include Renderer, Plugin (for NPAPI), Ppapi, Gpu-process, And Utility. When Using This Option, It May Be Helpful To Limit The Number Of Renderer Processes Spawned, Using: --renderer-process-limit=1 Image File Execution Options Using Image File Execution Options (IFEO) Will Not Work Because CreateProcess() Returns The Handle To The Debugger Process Instead Of The Intended Child Process. There Are Also Issues With The Sandbox. Time Travel Debugging You Can Do Time Travel Debugging Using WinDbg Preview (must Be Installed From The Microsoft Store). This Lets You Execute A Program Forward And Backwards. After Capturing A Trace, You Can Set Breakpoints And Step Through Code As Normal, But Also Provides 'backwards' Commands (g-, T-, P-) So That You Can Go Back And Forth Through The Execution. It Is Especially Useful To Set Data Breakpoints (ba Command) And Reverse Continuing, So You Can See When A Certain Variable Was Last Changed To Its Current Value. Chromium Specifics: The Type Of Injection The Time Travel Tracer Needs To Perform Is Incompatible With The Chromium Sandbox. In Order To Record A Trace, You'll Need To Run With --no-sandbox. Chromium Cannot Run Elevated With Administrator Privileges, So The "Launch Executable (advance)" Option Won't Work, You'll Need To Attach After The Process Has Already Launched Via The Checkbox In The Bottom Right. If You Need To Record Startup-like Things, You'll Have To Use --{browser,gpu,renderer,utility}-startup-dialog, Then Attach (and Hope The Relevant Code Hasn't Executed Before That Point). JsDbg -- Data Structure Visualization You Can Install JsDbg As A Plugin For WinDbg Or Visual Studio. It Interactively Lets You Look At Data Structures (such As The DOM Tree, Accessibility Tree, Layout Object Tree, And Others) In A Web Browser As You Debug. See The JsDbg Site For Some Screen Shots And Usage Examples. This Also Works When Examining Memory Dumps (though Not Minidumps), And Also Works Together With Time Travel Debugging. Visual Studio Hints Debug Visualizers Chrome's Custom Debug Visualizers Should Be Added To The Pdb Files And Automatically Picked Up By Visual Studio. The Definitions Are In //tools/win/DebugVisualizers If You Need To Modify Them (the BUILD.gn File There Has Additional Instructions). Don't Step Into Trivial Functions The Debugger Can Be Configured To Automatically Not Step Into Functions Based On Regular Expression. Edit Default.natstepfilter In The Following Directory: For Visual Studio 2015: C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Packages\Debugger\Visualizers (for All Users) Or %USERPROFILE%\My Documents\Visual Studio 2015\Visualizers (for The Current User Only) For Visual Studio 2017 Pro: C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\Packages\Debugger\Visualizers (for All Users) Or %USERPROFILE%\My Documents\Visual Studio 2017\Visualizers (for The Current User Only) Add Regular Expressions Of Functions To Not Step Into. Remember To Regex-escape And XML-escape Them, E.g. < For < And \. For A Literal Dot. Example: Operator New NoStepInto Operator Delete NoStepInto Std::.* NoStepInto WTF::.*Ptr ::.* NoStepInto This File Is Read At Start Of A Debugging Session (F5), So You Don't Need To Restart Visual Studio After Changing It. More Info: Microsoft Email Thread V8 And Chromium V8 Supports Many Command-line Flags That Are Useful For Debugging. V8 Command-line Flags Can Be Set Via The Chromium Command-line Flag --js-flags; For Instance: Chrome.exe --js-flags="--trace_exception --heap_stats" Note That Some V8 Command-line Flags Exist Only In The Debug Build Of V8. For A List Of All V8 Flags Try: Chrome.exe --js-flags="--help" Graphics Debugging GPU Acceleration Of Rendering Can Be More Easily Debugged With Tools. See: Graphics Debugging In Visual Studio 2013 Graphical Debugging With NVIDIA NSight Debugging On Another Machine Sometimes It's Useful To Debug Installation And Execution On A Machine Other Than Your Primary Build Box. To Run The Installer On Said Other Machine, First Build The Mini_installer Target On Your Main Build Machine (e.g., Autoninja -C Out\Debug Mini_installer). Next, On The Debug Machine: Make The Build Machine's Build Volume Available On The Debug Machine Either By Mounting It Locally (e.g., Z:\) Or By Crafting A UNC Path To It (e.g., \\builder\src) Open Up A Command Prompt And Change To A Local Disk Run Src\tools\win\copy-installer.bat In The Remote Checkout By Way Of The Mount (e.g., Z:\PATHTOCHECKOUT\src\...) Or UNC Path (e.g., \\builder\src\...). This Will Copy The Installer, DLLs, And PDBs Into Your Debug Machine's C:\out Or C:\build (depending On If You're Rocking The Component=shared_library Build Or Not) Run C:\out\Debug\mini_installer.exe With The Flags Of Your Choice To Install Chrome. This Can Take Some Time, Especially On A Slow Machine. Watch The Task Manager And Wait Until Mini_installer.exe Exits Before Trying To Launch Chrome (by Way Of The Shortcut(s) Created By The Installer) For Extra Pleasure, Add C:\out\Debug To Your _NT_SYMBOL_PATH Environment Variable Consider Reading The Documentation At The Top Of Copy-installer.bat To See How You Can Run It. It Tries To Be Smart And Copy The Right Things, But You May Need To Be Explicit (e.g., "copy-installer.bat Out Debug"). It Is Safe To Re-run The Script To Copy Only Modified Files (after A Rebuild, For Example). You Can Also Use The Zip Action Of The Isolate Scripts (tools\mb\mb.py) To Package All The Files For A Target Into A Single Zip File, For Example: Python Tools\mb\mb.py Zip Out/Release Base_unittests Base_unittests.zip Finding All Memory Allocations It Is Possible To Use Heap Snapshots To Get Call Stacks On All Outstanding Allocations That Use The OS Heap. This Works Particularly Well If Heap Snapshots Are Started As Soon As The Chrome Browser Process Is Created, But Before It Starts Running. Details Can Be Found In This Batch File. However, With PartitionAlloc Everywhere Most Chromium Allocations No Longer Use The Windows Heap So This Will Only Find A Subset Of Allocations, Mostly From OS DLLs. Find Memory Leaks Note: As With Heap Snapshots The Utility Of UMDH Is Greatly Reduced Now Because PartitionAlloc Everywhere Has Mostly Replaced The Windows Heap. The Windows Heap Manager Has A Really Useful Debug Flag, Where It Can Be Asked To Capture And Store A Stack Trace With Every Allocation. The Tool To Scrape These Stack Traces Out Of Processes Is UMDH, Which Comes With WinDbg. UMDH Is Great. It Will Capture A Snapshot Of The Heap State As Many Times As You Like, And It'll Do It Fairly Quickly. You Then Run It Again Against Either A Single Snapshot, Or A Pair Of Snapshots, At Which Time It'll Symbolize The Stack Traces And Aggregate Usage Up To Unique Stack Traces. Turning On The User Stack Trace Database For Chrome.exe With Gflags.exe Makes It Run Unbearably Slowly; However, Turning On The User Stack Trace Database On For The Browser Alone Is Just Fine. While It's Possible To Turn On The User Stack Database With The "!gflag" Debugging Extension, It's Too Late To Do This By The Time The Initial Debugger Breakpoint Hits. The Only Reasonable Way To Do This Is To Launch GFlags.exe, Enable The User Stack Trace Database (per Image Below), Launch Chrome Under The Debugger. Set A Breakpont When Chrome.dll Loads With "sxe Ld Chrome.dll". Step Up, To Allow Chrome.dll To Initialize. Disable The Stack Trace Database In GFlags.exe. Continue Chrome, Optionally Detaching The Debugger. Image GFlags.exe Settings For User Mode Stack Trace Database. If You Then Ever Suffer A Browser Memory Leak, You Can Snarf A Dump Of The Process With Umdh -p: > Chrome-browser-leak-umdh-dump.txt Which Can Then Typically Be "trivially" Analyzed To Find The Culprit. Miscellaneous Note That By Default Application Verifier Only Works With Non-official Builds Of Chromium. To Use Application Verifier On Official Builds You Need To Add --disable-features=RendererCodeIntegrity To Avoid Sandbox Crashes In Renderer Processes. See Crbug.com/1004989 For Details. See Also This Page. Application Verifier Is A Free Tool From Microsoft (available As Part Of The Windows SDK) That Can Be Used To Flush Out Programming Errors. Starting With M68 Application Verifier Can Be Enabled For Chrome.exe Without Needing To Disable The Sandbox. After Adding Chrome.exe To The List Of Applications To Be Stressed You Need To Expand The List Of Basics Checks And Disable The Leak Checks. You May Also Need To Disable Handles And Locks Checks Depending On Your Graphics Driver And Specific Chrome Version, But The Eventual Goal Is To Have Chrome Run With Handles And Locks Checks Enabled. When Bugs Are Found Chrome Will Trigger A Breakpoint So Running All Chrome Processes Under A Debugger Is Recommended. Chrome Will Run Much More Slowly Because Application Verifier Puts Every Heap Allocation On A Separate Page. Note That With PartitionAlloc Everywhere Most Chromium Allocations Don't Actually Go Through The Windows Heap And Are Therefore Unaffected By Application Verifier. You Can Check The Undocumented 'Cuzz' Checkbox In Application Verifier To Get The Windows Thread Scheduler To Add Some Extra Randomness In Order To Help Expose Race Conditions In Your Code. To Put A Breakpoint On CreateFile(), Add This Break Point: {,,kernel32.dll}_CreateFileW@28 {,,kernel32.dll} Specifies The DLL (context Operator). _ Prefix Means Extern "C". @28 Postfix Means _stdcall With The Stack Pop At The End Of The Function. I.e. The Number Of Arguments In BYTES. You Can Use DebugView From SysInternals Or Sawbuck To View LOG() Messages That Normally Go To Stderr On POSIX.

Watch The Task Manager And Wait Until Mini_installer.exe Exits Before Trying To Launch Chrome (by Way Of The Shortcut(s) Created By The Installer) For Extra Pleasure, Add C:\out\Debug To Your _NT_SYMBOL_PATH Environment Variable Consider Reading The Documentation At The Top Of Copy-installer.bat To See How You Can Run It. It Tries To Be Smart And Copy The Right Things, But You May Need To Be Explicit (e.g., "copy-installer.bat Out Debug"). It Is Safe To Re-run The Script To Copy Only Modified Files (after A Rebuild, For Example). You Can Also Use The Zip Action Of The Isolate Scripts (tools\mb\mb.py) To Package All The Files For A Target Into A Single Zip File, For Example: Python Tools\mb\mb.py Zip Out/Release Base_unittests Base_unittests.zip Finding All Memory Allocations It Is Possible To Use Heap Snapshots To Get Call Stacks On All Outstanding Allocations That Use The OS Heap. This Works Particularly Well If Heap Snapshots Are Started As Soon As The Chrome Browser Process Is Created, But Before It Starts Running. Details Can Be Found In This Batch File. However, With PartitionAlloc Everywhere Most Chromium Allocations No Longer Use The Windows Heap So This Will Only Find A Subset Of Allocations, Mostly From OS DLLs. Find Memory Leaks Note: As With Heap Snapshots The Utility Of UMDH Is Greatly Reduced Now Because PartitionAlloc Everywhere Has Mostly Replaced The Windows Heap. The Windows Heap Manager Has A Really Useful Debug Flag, Where It Can Be Asked To Capture And Store A Stack Trace With Every Allocation. The Tool To Scrape These Stack Traces Out Of Processes Is UMDH, Which Comes With WinDbg. UMDH Is Great. It Will Capture A Snapshot Of The Heap State As Many Times As You Like, And It'll Do It Fairly Quickly. You Then Run It Again Against Either A Single Snapshot, Or A Pair Of Snapshots, At Which Time It'll Symbolize The Stack Traces And Aggregate Usage Up To Unique Stack Traces. Turning On The User Stack Trace Database For Chrome.exe With Gflags.exe Makes It Run Unbearably Slowly; However, Turning On The User Stack Trace Database On For The Browser Alone Is Just Fine. While It's Possible To Turn On The User Stack Database With The "!gflag" Debugging Extension, It's Too Late To Do This By The Time The Initial Debugger Breakpoint Hits. The Only Reasonable Way To Do This Is To Launch GFlags.exe, Enable The User Stack Trace Database (per Image Below), Launch Chrome Under The Debugger. Set A Breakpont When Chrome.dll Loads With "sxe Ld Chrome.dll". Step Up, To Allow Chrome.dll To Initialize. Disable The Stack Trace Database In GFlags.exe. Continue Chrome, Optionally Detaching The Debugger. Image GFlags.exe Settings For User Mode Stack Trace Database. If You Then Ever Suffer A Browser Memory Leak, You Can Snarf A Dump Of The Process With Umdh -p: > Chrome-browser-leak-umdh-dump.txt Which Can Then Typically Be "trivially" Analyzed To Find The Culprit. Miscellaneous Note That By Default Application Verifier Only Works With Non-official Builds Of Chromium. To Use Application Verifier On Official Builds You Need To Add --disable-features=RendererCodeIntegrity To Avoid Sandbox Crashes In Renderer Processes. See Crbug.com/1004989 For Details. See Also This Page. Application Verifier Is A Free Tool From Microsoft (available As Part Of The Windows SDK) That Can Be Used To Flush Out Programming Errors. Starting With M68 Application Verifier Can Be Enabled For Chrome.exe Without Needing To Disable The Sandbox. After Adding Chrome.exe To The List Of Applications To Be Stressed You Need To Expand The List Of Basics Checks And Disable The Leak Checks. You May Also Need To Disable Handles And Locks Checks Depending On Your Graphics Driver And Specific Chrome Version, But The Eventual Goal Is To Have Chrome Run With Handles And Locks Checks Enabled. When Bugs Are Found Chrome Will Trigger A Breakpoint So Running All Chrome Processes Under A Debugger Is Recommended. Chrome Will Run Much More Slowly Because Application Verifier Puts Every Heap Allocation On A Separate Page. Note That With PartitionAlloc Everywhere Most Chromium Allocations Don't Actually Go Through The Windows Heap And Are Therefore Unaffected By Application Verifier. You Can Check The Undocumented 'Cuzz' Checkbox In Application Verifier To Get The Windows Thread Scheduler To Add Some Extra Randomness In Order To Help Expose Race Conditions In Your Code. To Put A Breakpoint On CreateFile(), Add This Break Point: {,,kernel32.dll}_CreateFileW@28 {,,kernel32.dll} Specifies The DLL (context Operator). _ Prefix Means Extern "C". @28 Postfix Means _stdcall With The Stack Pop At The End Of The Function. I.e. The Number Of Arguments In BYTES. You Can Use DebugView From SysInternals Or Sawbuck To View LOG() Messages That Normally Go To Stderr On POSIX.” Subjects and Themes:

Find The Chromium Logo The Chromium Projects Home Chromium ChromiumOS Quick Links Report Bugs Discuss Other Sites Chromium Blog Google Chrome Extensions Except As Otherwise Noted, The Content Of This Page Is Licensed Under A Creative Commons Attribution 2.5 License, And Examples Are Licensed Under The BSD License. Privacy Edit This Page For Developers > How-Tos > Debugging Chromium On Windows First See Get The Code For Checkout And Build Instructions. Getting Started You Can Use Visual Studio's Built-in Debugger Or WinDBG To Debug Chromium. You Don't Need To Use The IDE To Build In Order To Use The Debugger: Autoninja Is Used To Build Chromium And Most Developers Invoke It From A Command Prompt, And Then Open The IDE For Debugging As Necessary. To Start Debugging An Already-built Executable With Visual Studio Just Launch Visual Studio (2019 Or Higher) And Select File-> Open-> Project/Solution (Ctrl+Shift+O) And Select The Executable Of Interest. This Will Create A Solution With That Executable As The 'project'. You Can Then Launch The Debugger With F5 Or F11 Or From The Debug Menu. If You Right-click On The Executable In Solution Explorer And Select Properties Then You Can Edit Things Such As The Executable Path, Command-line Arguments, And Working Directory. You Can Add Additional Executables To The Solution By Using File-> Add-> Existing Project And Selecting Another Already-built Executable. You Can Select Which One To Debug By Right-clicking On One Of Them In Solution Explorer And Selecting Set As Startup Project. When Your Solution File Is Customized To Your Taste You Can Save It To A Directory Such As Out\solutions. Saving It There Helps Ensure That Relative Paths To Source Files, Printed From Build Commands, Will Correctly Identify The Source Files. The Tools Menu Can Be Used To Add Commands To Do Things Like Invoke Autoninja To Build Chrome, Compile The Selected Source File, Or Other Things. Visual Studio 2017 Is Not Recommended For Debugging Of Chromium - Use A Newer Version For Best Performance And Stability. Symbol_level=2 Is The Default On Windows And Gives Full Debugging Information With Types, Locals, Globals, Function Names, And Source/line Information. Symbol_level=1 Creates Smaller PDBs With Just Function Names, And Source/line Information - Source-level Debugging Is Still Supported (new From June 2019), But Local Variables And Type Information Are Missing. Symbol_level=0 Gives Extremely Limited Debugging Abilities, Mostly Just Viewing Call Stacks When Chromium Crashes. Browsing Source Code If You Use A Solution File Generated By Gn (gn Gen --ide=vs) Then Intellisense May Help You Navigate The Code. If This Doesn't Work Or If You Use A Solution Created As Above Then You May Want To Install VsChromium To Help Navigate The Code, As Well As Using Https://source.chromium.org. Profiles It's A Good Idea To Use A Different Chrome Profile For Your Debugging. If You Are Debugging Google Chrome Branded Builds, Or Use A Chromium Build As Your Primary Browser, The Profiles Can Collide So You Can't Run Both At Once, And Your Stable Browser Might See Profile Versions From The Future (Google Chrome And Chromium Use Different Profile Directories By Default So Won't Collide). Use The Command-line Option: --user-data-dir=C:\tmp\my_debug_profile (replace The Path As Necessary) Using The IDE, Go To The Debugging Tab Of The Properties Of The Chrome Project, And Set The Command Arguments. Chrome Debug Log Enable Chrome Debug Logging To A File By Passing --enable-logging --v=1 Command-line Flags At Startup. Debug Builds Place The Chrome_debug.log File In The Out\Debug Directory. Release Builds Place The File In The Top Level Of The User Data Chromium App Directory, Which Is OS-version-dependent. For More Information, See Logging And User Data Directory Details. Symbol Server If You Are Debugging Official Google Chrome Release Builds, Use The Symbol Server: Https://chromium-browser-symsrv.commondatastorage.googleapis.com In Visual Studio, This Goes In Tools > Options Under Debugging > Symbols. You Should Set Up A Local Cache In A Empty Directory On Your Computer. In Windbg You Can Add This To Your Symbol Server Search Path With The Command Below, Where C:\symbols Is A Local Cache Directory: .sympath+ SRV\*C:\symbols\*https://chromium-browser-symsrv.commondatastorage.googleapis.com Alternately, You Can Set The _NT_SYMBOL_PATH Environment Variable To Include Both The Microsoft And Google Symbol Servers - VS, Windbg, And Other Tools Should Both Respect This Environment Variable: _NT_SYMBOL_PATH=SRV\*C:\symbols\*https://msdl.microsoft.com/download/symbols;SRV\*C:\symbols\*https://chromium-browser-symsrv.commondatastorage.googleapis.com Note That Symbol Servers Will Let The Debuggers Download Both The PE Files (DLLs And EXEs) And The PDB Files. Chrome Often Loads Third Party Libraries And Partial Symbols For Some Of These Are Also Public. For Example: AMD: Https://download.amd.com/dir/bin Nvidia: Https://driver-symbols.nvidia.com/ Intel: Https://software.intel.com/sites/downloads/symbols/ For Example, For Completeness, The Following Symbol Server Environment Variable Will Resolve All Of The Above Sources - But This Is More Than Is Normally Needed: _NT_SYMBOL_PATH=SRV\*C:\symbols\*https://msdl.microsoft.com/download/symbols;SRV\*C:\symbols\*https://chromium-browser-symsrv.commondatastorage.googleapis.com;SRV\*C:\symbols\*https://download.amd.com/dir/bin;SRV\*C:\symbols\*https://driver-symbols.nvidia.com/;SRV\*C:\symbols\*https://software.intel.com/sites/downloads/symbols/ Source Indexing You Should Set Up Source Indexing In Your Debugger (.srcfix In Windbg, Tools-> Options-> Debugging-> General-> Enable Source Server Support In Visual Studio) So That The Correct Source Files Will Automatically Be Downloaded Based On Information In The Downloaded Symbols. Additionally, You Must Have Python In Your Path In Order For The Command That Fetches Source Files To Succeed; Launching The Debugger From The Same Environment As Where You Build Chromium Is An Easy Way To Ensure It's Present. This Is Highly Recommended When Debugging Released Google Chrome Builds Or Looking At Crash Dumps. Having The Correct Version Of The Source Files Automatically Show Up Saves Significant Time So You Should Definitely Set This. Multi-process Issues Chromium Can Be Challenging To Debug Because Of Its Multi-process Architecture. When You Select Run In The Debugger, Only The Main Browser Process Will Be Debugged. The Code That Actually Renders Web Pages (the Renderer) And The Plugins Will Be In Separate Processes That's Not (yet!) Being Debugged. The ProcessExplorer Tool Has A Process Tree View Where You Can See How These Processes Are Related. You Can Also Get The Process IDs Associated With Each Tab From The Chrome Task Manager (right-click On An Empty Area Of The Window Title Bar To Open). Automatically Attach To Child Processes There Are Two Visual Studio Extensions That Enable The Debugger To Automatically Attach To All Chrome Processes, So You Can Debug All Of Chrome At Once. Microsoft's Child Process Debugging Power Tool Is A Standalone Extension For This, And VsChromium Is Another Option That Bundles Many Other Additional Features. In Addition To Installing One Of These Extensions, You Must Run Visual Studio As Administrator, Or It Will Silently Fail To Attach To Some Of Chrome's Child Processes. Single-process Mode One Way To Debug Issues Is To Run Chromium In Single-process Mode. This Will Allow You To See The Entire State Of The Program Without Extra Work (although It Will Still Have Many Threads). To Use Single-process Mode, Add The Command-line Flag --single-process This Approach Isn't Perfect Because Some Problems Won't Manifest Themselves In This Mode And Some Features Don't Work And Worker Threads Are Still Spawned Into New Processes. Manually Attaching To A Child Process You Can Attach To The Running Child Processes With The Debugger. Select Tools > Attach To Process And Click The Chrome.exe Process You Want To Attach To. Before Attaching, Make Sure You Have Selected Only Native Code When Attaching To The Process This Is Done By Clicking Select... In The Attach To Process Window And Only Checking Native. If You Forget This, It May Attempt To Attach In "WebKit" Mode To Debug JavaScript, And You'll Get An Error Message "An Operation Is Not Legal In The Current State." You Can Now Debug The Two Processes As If They Were One. When You Are Debugging Multiple Processes, Open The Debug > Windows > Processes Window To Switch Between Them. Sometimes You Are Debugging Something That Only Happens On Startup, And Want To See The Child Process As Soon As It Starts. Use: --renderer-startup-dialog --no-sandbox You Have To Disable The Sandbox Or The Dialog Box Will Be Prohibited From Showing. When The Dialog Appears, Visit Tools > Attach To Process And Attach To The Process Showing The Renderer Startup Dialog. Now You're Debugging In The Renderer And Can Continue Execution By Pressing OK In The Dialog. Startup Dialogs Also Exist For Other Child Process Types: --gpu-startup-dialog, --ppapi-startup-dialog, --utility-startup-dialog, --plugin-startup-dialog (for NPAPI). For Utilities, You Can Add A Service Type --utility-startup-dialog=data_decoder.mojom.DataDecoderService. You Can Also Try The Vs-chromium Plug-in To Attach To The Right Processes. Semi-automatically Attaching The Debugger To Child Processes The Following Flags Cause Child Processes To Wait For 60 Seconds In A Busy Loop For A Debugger To Attach To The Process. Once Either Condition Is True, It Continues On; No Exception Is Thrown. --wait-for-debugger-children[=filter] The Filter, If Provided, Will Fire Only If It Matches The --type Parameter To The Process. Values Include Renderer, Plugin (for NPAPI), Ppapi, Gpu-process, And Utility. When Using This Option, It May Be Helpful To Limit The Number Of Renderer Processes Spawned, Using: --renderer-process-limit=1 Image File Execution Options Using Image File Execution Options (IFEO) Will Not Work Because CreateProcess() Returns The Handle To The Debugger Process Instead Of The Intended Child Process. There Are Also Issues With The Sandbox. Time Travel Debugging You Can Do Time Travel Debugging Using WinDbg Preview (must Be Installed From The Microsoft Store). This Lets You Execute A Program Forward And Backwards. After Capturing A Trace, You Can Set Breakpoints And Step Through Code As Normal, But Also Provides 'backwards' Commands (g-, T-, P-) So That You Can Go Back And Forth Through The Execution. It Is Especially Useful To Set Data Breakpoints (ba Command) And Reverse Continuing, So You Can See When A Certain Variable Was Last Changed To Its Current Value. Chromium Specifics: The Type Of Injection The Time Travel Tracer Needs To Perform Is Incompatible With The Chromium Sandbox. In Order To Record A Trace, You'll Need To Run With --no-sandbox. Chromium Cannot Run Elevated With Administrator Privileges, So The "Launch Executable (advance)" Option Won't Work, You'll Need To Attach After The Process Has Already Launched Via The Checkbox In The Bottom Right. If You Need To Record Startup-like Things, You'll Have To Use --{browser,gpu,renderer,utility}-startup-dialog, Then Attach (and Hope The Relevant Code Hasn't Executed Before That Point). JsDbg -- Data Structure Visualization You Can Install JsDbg As A Plugin For WinDbg Or Visual Studio. It Interactively Lets You Look At Data Structures (such As The DOM Tree, Accessibility Tree, Layout Object Tree, And Others) In A Web Browser As You Debug. See The JsDbg Site For Some Screen Shots And Usage Examples. This Also Works When Examining Memory Dumps (though Not Minidumps), And Also Works Together With Time Travel Debugging. Visual Studio Hints Debug Visualizers Chrome's Custom Debug Visualizers Should Be Added To The Pdb Files And Automatically Picked Up By Visual Studio. The Definitions Are In //tools/win/DebugVisualizers If You Need To Modify Them (the BUILD.gn File There Has Additional Instructions). Don't Step Into Trivial Functions The Debugger Can Be Configured To Automatically Not Step Into Functions Based On Regular Expression. Edit Default.natstepfilter In The Following Directory: For Visual Studio 2015: C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Packages\Debugger\Visualizers (for All Users) Or %USERPROFILE%\My Documents\Visual Studio 2015\Visualizers (for The Current User Only) For Visual Studio 2017 Pro: C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\Packages\Debugger\Visualizers (for All Users) Or %USERPROFILE%\My Documents\Visual Studio 2017\Visualizers (for The Current User Only) Add Regular Expressions Of Functions To Not Step Into. Remember To Regex-escape And XML-escape Them, E.g. < For < And \. For A Literal Dot. Example: Operator New NoStepInto Operator Delete NoStepInto Std::.* NoStepInto WTF::.*Ptr ::.* NoStepInto This File Is Read At Start Of A Debugging Session (F5), So You Don't Need To Restart Visual Studio After Changing It. More Info: Microsoft Email Thread V8 And Chromium V8 Supports Many Command-line Flags That Are Useful For Debugging. V8 Command-line Flags Can Be Set Via The Chromium Command-line Flag --js-flags; For Instance: Chrome.exe --js-flags="--trace_exception --heap_stats" Note That Some V8 Command-line Flags Exist Only In The Debug Build Of V8. For A List Of All V8 Flags Try: Chrome.exe --js-flags="--help" Graphics Debugging GPU Acceleration Of Rendering Can Be More Easily Debugged With Tools. See: Graphics Debugging In Visual Studio 2013 Graphical Debugging With NVIDIA NSight Debugging On Another Machine Sometimes It's Useful To Debug Installation And Execution On A Machine Other Than Your Primary Build Box. To Run The Installer On Said Other Machine, First Build The Mini_installer Target On Your Main Build Machine (e.g., Autoninja -C Out\Debug Mini_installer). Next, On The Debug Machine: Make The Build Machine's Build Volume Available On The Debug Machine Either By Mounting It Locally (e.g., Z:\) Or By Crafting A UNC Path To It (e.g., \\builder\src) Open Up A Command Prompt And Change To A Local Disk Run Src\tools\win\copy-installer.bat In The Remote Checkout By Way Of The Mount (e.g., Z:\PATHTOCHECKOUT\src\...) Or UNC Path (e.g., \\builder\src\...). This Will Copy The Installer, DLLs, And PDBs Into Your Debug Machine's C:\out Or C:\build (depending On If You're Rocking The Component=shared_library Build Or Not) Run C:\out\Debug\mini_installer.exe With The Flags Of Your Choice To Install Chrome. This Can Take Some Time, Especially On A Slow Machine. Watch The Task Manager And Wait Until Mini_installer.exe Exits Before Trying To Launch Chrome (by Way Of The Shortcut(s) Created By The Installer) For Extra Pleasure, Add C:\out\Debug To Your _NT_SYMBOL_PATH Environment Variable Consider Reading The Documentation At The Top Of Copy-installer.bat To See How You Can Run It. It Tries To Be Smart And Copy The Right Things, But You May Need To Be Explicit (e.g., "copy-installer.bat Out Debug"). It Is Safe To Re-run The Script To Copy Only Modified Files (after A Rebuild, For Example).

Privacy Edit this page For Developers > How-Tos > Debugging Chromium on Windows First see get the code for checkout and build instructions. Getting started You can use Visual Studio's built-in debugger or WinDBG to debug Chromium. You don't need to use the IDE to build in order to use the debugger: autoninja is used to build Chromium and most developers invoke it from a command prompt, and then open the IDE for debugging as necessary. To start debugging an already-built executable with Visual Studio just launch Visual Studio (2019 or higher) and select File-> Open-> Project/Solution (Ctrl+Shift+O) and select the executable of interest. This will create a solution with that executable as the 'project'. You can then launch the debugger with F5 or F11 or from the Debug menu. If you right-click on the executable in Solution Explorer and select properties then you can edit things such as the executable path, command-line arguments, and working directory. You can add additional executables to the solution by using File-> Add-> Existing Project and selecting another already-built executable. You can select which one to debug by right-clicking on one of them in Solution Explorer and selecting Set as Startup Project. When your solution file is customized to your taste you can save it to a directory such as out\solutions. Saving it there helps ensure that relative paths to source files, printed from build commands, will correctly identify the source files. The Tools menu can be used to add commands to do things like invoke autoninja to build Chrome, compile the selected source file, or other things. Visual Studio 2017 is not recommended for debugging of Chromium - use a newer version for best performance and stability. symbol_level=2 is the default on Windows and gives full debugging information with types, locals, globals, function names, and source/line information. symbol_level=1 creates smaller PDBs with just function names, and source/line information - source-level debugging is still supported (new from June 2019), but local variables and type information are missing. symbol_level=0 gives extremely limited debugging abilities, mostly just viewing call stacks when Chromium crashes. Browsing source code If you use a solution file generated by gn ( gn gen --ide=vs ) then Intellisense may help you navigate the code. If this doesn't work or if you use a solution created as above then you may want to install VsChromium to help navigate the code, as well as using https://source.chromium.org . Profiles It's a good idea to use a different Chrome profile for your debugging. If you are debugging Google Chrome branded builds, or use a Chromium build as your primary browser, the profiles can collide so you can't run both at once, and your stable browser might see profile versions from the future (Google Chrome and Chromium use different profile directories by default so won't collide). Use the command-line option: --user-data-dir =C:\tmp\my_debug_profile (replace the path as necessary) Using the IDE, go to the Debugging tab of the properties of the chrome project, and set the Command Arguments. Chrome debug log Enable Chrome debug logging to a file by passing --enable-logging --v=1 command-line flags at startup. Debug builds place the chrome_debug.log file in the out\Debug directory. Release builds place the file in the top level of the user data Chromium app directory, which is OS-version-dependent. For more information, see logging and user data directory details. Symbol server If you are debugging official Google Chrome release builds, use the symbol server: https://chromium-browser-symsrv.commondatastorage.googleapis.com In Visual Studio, this goes in Tools > Options under Debugging > Symbols . You should set up a local cache in a empty directory on your computer. In windbg you can add this to your symbol server search path with the command below, where C:\symbols is a local cache directory: .sympath+ SRV\*C:\symbols\*https://chromium-browser-symsrv.commondatastorage.googleapis.com Alternately, You can set the _NT_SYMBOL_PATH environment variable to include both the Microsoft and Google symbol servers - VS, windbg, and other tools should both respect this environment variable: _NT_SYMBOL_PATH =SRV\*C:\symbols\*https://msdl.microsoft.com/download/symbols ;SRV\*C:\symbols\*https://chromium-browser-symsrv.commondatastorage.googleapis.com Note that symbol servers will let the debuggers download both the PE files (DLLs and EXEs) and the PDB files. Chrome often loads third party libraries and partial symbols for some of these are also public. For example: AMD : https://download.amd.com/dir/bin Nvidia : https://driver-symbols.nvidia.com/ Intel : https://software.intel.com/sites/downloads/symbols/ For example, for completeness, the following symbol server environment variable will resolve all of the above sources - but this is more than is normally needed: _NT_SYMBOL_PATH=SRV\*C:\symbols\*https://msdl.microsoft.com/download/symbols;SRV\*C:\symbols\*https://chromium-browser-symsrv.commondatastorage.googleapis.com;SRV\*C:\symbols\*https://download.amd.com/dir/bin;SRV\*C:\symbols\*https://driver-symbols.nvidia.com/;SRV\*C:\symbols\*https://software.intel.com/sites/downloads/symbols/ Source indexing You should set up source indexing in your debugger ( .srcfix in windbg, Tools-> Options-> Debugging-> General-> Enable source server support in Visual Studio) so that the correct source files will automatically be downloaded based on information in the downloaded symbols. Additionally, you must have python in your path in order for the command that fetches source files to succeed; launching the debugger from the same environment as where you build Chromium is an easy way to ensure it's present. This is highly recommended when debugging released Google Chrome builds or looking at crash dumps. Having the correct version of the source files automatically show up saves significant time so you should definitely set this. Multi-process issues Chromium can be challenging to debug because of its multi-process architecture . When you select Run in the debugger, only the main browser process will be debugged. The code that actually renders web pages (the Renderer) and the plugins will be in separate processes that's not (yet!) being debugged. The ProcessExplorer tool has a process tree view where you can see how these processes are related. You can also get the process IDs associated with each tab from the Chrome Task Manager (right-click on an empty area of the window title bar to open). Automatically attach to child processes There are two Visual Studio extensions that enable the debugger to automatically attach to all Chrome processes, so you can debug all of Chrome at once. Microsoft's Child Process Debugging Power Tool is a standalone extension for this, and VsChromium is another option that bundles many other additional features. In addition to installing one of these extensions, you must run Visual Studio as Administrator, or it will silently fail to attach to some of Chrome's child processes. Single-process mode One way to debug issues is to run Chromium in single-process mode. This will allow you to see the entire state of the program without extra work (although it will still have many threads). To use single-process mode, add the command-line flag --single-process This approach isn't perfect because some problems won't manifest themselves in this mode and some features don't work and worker threads are still spawned into new processes. Manually attaching to a child process You can attach to the running child processes with the debugger. Select Tools > Attach to Process and click the chrome.exe process you want to attach to. Before attaching, make sure you have selected only Native code when attaching to the process This is done by clicking Select... in the Attach to Process window and only checking Native. If you forget this, it may attempt to attach in "WebKit" mode to debug JavaScript, and you'll get an error message "An operation is not legal in the current state." You can now debug the two processes as if they were one. When you are debugging multiple processes, open the Debug > Windows > Processes window to switch between them. Sometimes you are debugging something that only happens on startup, and want to see the child process as soon as it starts. Use: --renderer-startup-dialog --no-sandbox You have to disable the sandbox or the dialog box will be prohibited from showing. When the dialog appears, visit Tools > Attach to Process and attach to the process showing the Renderer startup dialog. Now you're debugging in the renderer and can continue execution by pressing OK in the dialog. Startup dialogs also exist for other child process types: --gpu-startup-dialog , --ppapi-startup-dialog , --utility-startup-dialog , --plugin-startup-dialog (for NPAPI). For utilities, you can add a service type --utility-startup-dialog=data_decoder.mojom.DataDecoderService . You can also try the vs-chromium plug-in to attach to the right processes. Semi-automatically attaching the debugger to child processes The following flags cause child processes to wait for 60 seconds in a busy loop for a debugger to attach to the process. Once either condition is true, it continues on; no exception is thrown. --wait-for-debugger-children [=filter] The filter, if provided, will fire only if it matches the --type parameter to the process. Values include renderer , plugin (for NPAPI), ppapi , gpu-process , and utility . When using this option, it may be helpful to limit the number of renderer processes spawned, using: --renderer-process-limit = 1 Image File Execution Options Using Image File Execution Options (IFEO) will not work because CreateProcess() returns the handle to the debugger process instead of the intended child process. There are also issues with the sandbox. Time travel debugging You can do time travel debugging using WinDbg Preview (must be installed from the Microsoft Store). This lets you execute a program forward and backwards. After capturing a trace, you can set breakpoints and step through code as normal, but also provides 'backwards' commands (g-, t-, p-) so that you can go back and forth through the execution. It is especially useful to set data breakpoints ( ba command ) and reverse continuing, so you can see when a certain variable was last changed to its current value. Chromium specifics: The type of injection the time travel tracer needs to perform is incompatible with the Chromium sandbox. In order to record a trace, you'll need to run with --no-sandbox . Chromium cannot run elevated with Administrator privileges, so the "Launch executable (advance)" option won't work, you'll need to attach after the process has already launched via the checkbox in the bottom right. If you need to record startup-like things, you'll have to use --{browser,gpu,renderer,utility}-startup-dialog, then attach (and hope the relevant code hasn't executed before that point). JsDbg -- data structure visualization You can install JsDbg as a plugin for WinDbg or Visual Studio . It interactively lets you look at data structures (such as the DOM tree, Accessibility tree, layout object tree, and others) in a web browser as you debug. See the JsDbg site for some screen shots and usage examples. This also works when examining memory dumps (though not minidumps), and also works together with time travel debugging. Visual Studio hints Debug visualizers Chrome's custom debug visualizers should be added to the pdb files and automatically picked up by Visual Studio. The definitions are in //tools/win/DebugVisualizers if you need to modify them (the BUILD.gn file there has additional instructions). Don't step into trivial functions The debugger can be configured to automatically not step into functions based on regular expression. Edit default.natstepfilter in the following directory: For Visual Studio 2015: C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Packages\Debugger\Visualizers (for all users) or %USERPROFILE%\My Documents\Visual Studio 2015\Visualizers (for the current user only) For Visual Studio 2017 Pro: C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\Packages\Debugger\Visualizers (for all users) or %USERPROFILE%\My Documents\Visual Studio 2017\Visualizers (for the current user only) Add regular expressions of functions to not step into. Remember to regex-escape and XML-escape them, e.g. < for < and \. for a literal dot. Example: < Function > < Name > operator new </ Name > < Action > NoStepInto </ Action > </ Function > < Function > < Name > operator delete </ Name > < Action > NoStepInto </ Action > </ Function > <!-- Skip everything in std --> < Function > < Name > std::.* </ Name > < Action > NoStepInto </ Action > </ Function > <!-- all methods on WebKit OwnPtr and variants, ... WTF::*Ptr<*>::* --> < Function > < Name > WTF::.*Ptr<.*>::.* </ Name > < Action > NoStepInto </ Action > </ Function > This file is read at start of a debugging session (F5), so you don't need to restart Visual Studio after changing it. More info: Microsoft email thread V8 and Chromium V8 supports many command-line flags that are useful for debugging. V8 command-line flags can be set via the Chromium command-line flag --js-flags; for instance: chrome.exe --js-flags= "--trace_exception --heap_stats" Note that some V8 command-line flags exist only in the debug build of V8. For a list of all V8 flags try: chrome.exe --js-flags= "--help" Graphics debugging GPU Acceleration of rendering can be more easily debugged with tools. See: Graphics Debugging in Visual Studio 2013 Graphical debugging with NVIDIA NSight Debugging on another machine Sometimes it's useful to debug installation and execution on a machine other than your primary build box. To run the installer on said other machine, first build the mini_installer target on your main build machine (e.g., autoninja -C out\Debug mini_installer). Next, on the debug machine: Make the build machine's build volume available on the debug machine either by mounting it locally (e.g., Z:\) or by crafting a UNC path to it (e.g., \\builder\src) Open up a command prompt and change to a local disk Run src\tools\win\ copy-installer.bat in the remote checkout by way of the mount (e.g., Z:\PATHTOCHECKOUT\src\...) or UNC path (e.g., \\builder\src\...). This will copy the installer, DLLs, and PDBs into your debug machine's C:\out or C:\build (depending on if you're rocking the component=shared_library build or not) Run C:\out\Debug\mini_installer.exe with the flags of your choice to install Chrome. This can take some time, especially on a slow machine. Watch the Task Manager and wait until mini_installer.exe exits before trying to launch Chrome (by way of the shortcut(s) created by the installer) For extra pleasure, add C:\out\Debug to your _NT_SYMBOL_PATH environment variable Consider reading the documentation at the top of copy-installer.bat to see how you can run it. It tries to be smart and copy the right things, but you may need to be explicit (e.g., "copy-installer.bat out Debug"). It is safe to re-run the script to copy only modified files (after a rebuild, for example). You can also use the zip action of the isolate scripts (tools\mb\mb.py) to package all the files for a target into a single zip file, for example: python tools\mb\mb.py zip out/Release base_unittests base_unittests. zip Finding all memory allocations It is possible to use Heap Snapshots to get call stacks on all outstanding allocations that use the OS heap. This works particularly well if heap snapshots are started as soon as the Chrome browser process is created, but before it starts running. Details can be found in this batch file . However, with PartitionAlloc Everywhere most Chromium allocations no longer use the Windows heap so this will only find a subset of allocations, mostly from OS DLLs. Find memory leaks Note: as with Heap Snapshots the utility of UMDH is greatly reduced now because PartitionAlloc Everywhere has mostly replaced the Windows heap. The Windows heap manager has a really useful debug flag, where it can be asked to capture and store a stack trace with every allocation. The tool to scrape these stack traces out of processes is UMDH, which comes with WinDbg . UMDH is great. It will capture a snapshot of the heap state as many times as you like, and it'll do it fairly quickly. You then run it again against either a single snapshot, or a pair of snapshots, at which time it'll symbolize the stack traces and aggregate usage up to unique stack traces. Turning on the user stack trace database for chrome.exe with gflags.exe makes it run unbearably slowly; however, turning on the user stack trace database on for the browser alone is just fine. While it's possible to turn on the user stack database with the "!gflag" debugging extension, it's too late to do this by the time the initial debugger breakpoint hits. The only reasonable way to do this is to Launch GFlags.exe, Enable the user stack trace database (per image below), Launch Chrome under the debugger. Set a breakpont when chrome.dll loads with "sxe ld chrome.dll". Step up, to allow Chrome.dll to initialize. Disable the stack trace database in GFlags.exe. Continue chrome, optionally detaching the debugger. GFlags.exe settings for user mode stack trace database. If you then ever suffer a browser memory leak, you can snarf a dump of the process with umdh - p :<my browser pid> > chrome-browser-leak-umdh-dump.txt which can then typically be "trivially" analyzed to find the culprit. Miscellaneous Note that by default Application Verifier only works with non-official builds of Chromium. To use Application Verifier on official builds you need to add --disable-features=RendererCodeIntegrity to avoid sandbox crashes in renderer processes. See crbug.com/1004989 for details. See also this page . Application Verifier is a free tool from Microsoft (available as part of the Windows SDK) that can be used to flush out programming errors. Starting with M68 Application Verifier can be enabled for chrome.exe without needing to disable the sandbox. After adding chrome.exe to the list of applications to be stressed you need to expand the list of Basics checks and disable the Leak checks. You may also need to disable Handles and Locks checks depending on your graphics driver and specific Chrome version, but the eventual goal is to have Chrome run with Handles and Locks checks enabled. When bugs are found Chrome will trigger a breakpoint so running all Chrome processes under a debugger is recommended. Chrome will run much more slowly because Application Verifier puts every heap allocation on a separate page. Note that with PartitionAlloc Everywhere most Chromium allocations don't actually go through the Windows heap and are therefore unaffected by Application Verifier. You can check the undocumented 'Cuzz' checkbox in Application Verifier to get the Windows thread scheduler to add some extra randomness in order to help expose race conditions in your code. To put a breakpoint on CreateFile(), add this break point: {,,kernel32.dll}_CreateFileW@28 {,,kernel32.dll} specifies the DLL (context operator). _ prefix means extern "C". @28 postfix means _stdcall with the stack pop at the end of the function. i.e. the number of arguments in BYTES. You can use DebugView from SysInternals or sawbuck to view LOG() messages that normally go to stderr on POSIX.

22Development Of A Web-based Distributed Interactive Simulation (DIS) Environment Using Javascript
By Hsiao, Chen-Fu
This thesis investigated the current infrastructure for web-based simulations using the DIS network protocol. The main technologies studied were WebSockets, WebRTC and WebGL. This thesis sought readily available means to establish networks for interchanging DIS message (PDUs), so the WebSocket gateway server from Open-DIS project was used to construct a Client-Server structure and PeerJS API was used to construct a peer-to-peer structure. WebGL was used to create a scene and render 3D models in browsers. A first-person-shooter tank game was used as a test application with both WebSocket and WebRTC infrastructures. Experiments in this thesis included measuring the rate of sending and receiving DIS packets and analysis of the tank game by profiling tools. All the experiments were run on Chrome and Firefox browsers in a closed network. The experimental results showed that both WebSocket and WebRTC infrastructures were competent enough to support web-based DIS simulation. The results also found the significant differences of performance between Chrome and Firefox. Currently, the best performance is provided by the combination of Firefox using the WebRTC framework. The analysis of the tank game showed that most of the browser’s computational resources were spent on the WebGL graphics, with only a small percentage of the resources expended on exchanging DIS packets.

24Microsoft Research Audio 103385: J Is For JavaScript: A Direct-style Correspondence Between Algol-like Languages And JavaScript Using First-class Continuations
By Microsoft Research
It is a time-honored fashion to implement a domain-specific language (DSL) by translation to a general-purpose language. Such an implementation is more portable, but an unidiomatic translation jeopardizes performance because, in practice, language implementations favor the common cases. This tension arises especially when the domain calls for complex control structures. We illustrate this tension by revisiting Landin's original correspondence between Algol and Church's lambda-notation. We translate domain-specific programs with lexically scoped jumps to JavaScript. Our translation produces the same block structure and binding structure as in the source program, a la Abdali. The target code uses a control operator in direct style, a la Landin. In fact, the control operator used is almost Landin's J---hence our title. Our translation thus complements a continuation-passing translation a la Steele. These two extreme translations require JavaScript implementations to cater either for first-class continuations, as Rhino does, or for proper tail recursion. Less extreme translations should emit more idiomatic control-flow instructions such as for, break, and throw. The present experiment leads us to conclude that translations should preserve not just the data structures and the block structure of a source program, but also its control structure. We thus identify a new class of use cases for control structures in JavaScript, namely the idiomatic translation of control structures from DSLs. ©2009 Microsoft Corporation. All rights reserved.

44Enhancing Data Retrieval Efficiency In Large-scale Javascript Object Notation Datasets By Using Indexing Techniques
By Bowonsak Srisungsittisunti, Jirawat Duangkaew, Sakorn Mekruksavanich, Nakarin Chaikaew, Pornthep Rojanavasu
The use of Javascript object notation (JSON) format as a not only structured query language (NoSQL) storage solution has grown in popularity, but has presented technical challenges, particularly in indexing large-scale JSON files. This has resulted in slow data retrieval, especially for larger datasets. In this study, we propose the use of JSON datasets to preserve data in resource survey processes. We conducted experiments on a 32-gigabyte dataset containing 1,000,000 transactions in JSON format and implemented two indexing methods, dense and sparse, to improve retrieval efficiency. Additionally, we determined the optimal range of segment sizes for the indexing methods. Our findings revealed that adopting dense indexing reduced data retrieval time from 15,635 milliseconds to 55 milliseconds in one-to-one data retrieval, and from 38,300 milliseconds to 1 millisecond in the absence of keywords. In contrast, using sparse indexing reduced data retrieval time from 33,726 milliseconds to 36 milliseconds in one-to-many data retrieval and from 47,203 milliseconds to 0.17 milliseconds when keywords were not found. Furthermore, we discovered that the optimal segment size range was between 20,000 and 200,000 transactions for both dense and sparse indexing.

50ERIC ED425731: Using Frames And JavaScript To Automate Teacher-Side Web Page Navigation For Classroom Presentations.
By ERIC
HTML provides a platform-independent way of creating and making multimedia presentations for classroom instruction and making that content available on the Internet. However, time in class is very valuable, so that any way to automate or otherwise assist the presenter in Web page navigation during class can save valuable seconds. This paper describes the use of frames and JavaScript in conjunction with VGA/TV project systems to automate teacher-side Web page navigation for classroom presentations. The methods used are not visually distracting to the students during class, do not require Web server support or an Internet connection (i.e., they can be used with only local hard drive access), and can be used independently of the student-side Web page access so that students who may or may not have browsers that support the features used on the teacher side can still access the content of those pages.

4Mysteries of London Vol. I part 2

The Mysteries of London was a best-selling novel in mid-Victorian England. The first series was published in weekly instalments from 1844-46, priced at a penny each. Serialised novels sold in this way were known as Penny Dreadfuls … without any claim to literary greatness, they sought to provide ongoing entertainment for the popular audience.<br /><br /> When first published, this book was intended for an adult audience. The crime and vice involved would have had a terrible effect on the Young Mind of the Victorian Era. However, it’s less likely to cause offence or concern now, though I don’t recommend it for younger children. - Summary by Cori

65 Science Fiction Stories by Mack Reynolds
By Mack Reynolds
Five early stories by one of my favorite SF writers, Mack Reynolds. Medal of Honor is an intriguing look into the mind of someone who is above the law; who cannot commit a crime. How will he act? especially if he is a self centered drunk? Potential Enemy is story about the sad state of human minds that are ruled by fear and paranoia. Happy Ending is an SF story about the far future when the last solar system wide dictator has been finally defeated and what will he do? What will he do? This is also an exploration of mental megalomania and it's effects. His happy ending is perhaps suitable, but probably not so happy. A Gun For Hire explores in a light-hearted but painful way, the fact that hired guns are just that: hired. The final story is the funniest of the lot the and is set in Tangiers in the present or very near future. UFO's are a crackpot idea, right? Well, perhaps not. - Summary by Phil Chenevert

9Wagner, the Wehr-Wolf
By George W. M. Reynolds

Wagner is a poor, lonely old shepherd living on the edge of the Black Forest. In a devil's pact he gains youth and wealth for the price of transforming into a ravenous wolf once a month. This book contains everything from murder, kidnap, robbery, sadistic nuns and lust to war in sixteenth century Italy. Originally published in a serialised form, this penny dreadful is definitely not a piece of fine literature, but is hopefully entertaining. <br> </br> This book contains racial and other prejudices that were once commonplace. They are retained, as originally written in this recording, because to do otherwise would be to deny they existed. - Summary by clarinetcarrot

14Green Valley
By Katharine Yirsa Reynolds

"Traveling men have a poor opinion of it. Ministers of the gospel have been known to despair of it. Socially ambitious matrons move out of it, or, if that is not possible, despise it. Real estate men can not get rich in it. And humorless folk sometimes have a hard, sad time of it in Green Valley". This is an authentic novel about a small town in the USA. A book about what people tell and don't tell, loves and losses, and the importance of community. Community life which did not go away. - Summary by Stav Nisser

15Adaptation
By Mack Reynolds

In 1960 when this was published, the Cold War was at its height. Communism and Free Enterprise (Democracy) were locked in a ferocious struggle to prove that their political ideology was the best form of government for human kind. No holds were barred in this fight; propaganda was poured forth by both sides in a constant push to be seen as better, more progressive, more productive. Nuclear war was a constant threat. I know, I lived through that time. Thankfully the world came through that stressful time without a hot war but the question was not really settled: which is the better system? This story explores that question. "Hardly had man solved his basic problems on the planet of his origin than he began to fumble into space. Barely a century had elapsed in the exploration of the Solar System than he began to grope for the stars. And suddenly, with an all but religious zeal, mankind conceived its fantasy dream of populating the galaxy." summary by Phil chenevert and the author
