A browser window running a Native Client application has at least two processes associated with it: From the Task Manager you can view the changing memory allocations of all the processes associated with a Native Client application.

Each process has its own memory footprint. You can also see the rendering rate displayed as frames per second FPS. Note that the computation of render frames can be performed in any process, but the rendering itself is always done in the top level application process, so look for the rendering rate there.

Native Client prints warning and error messages to stdout and stderr. When the JavaScript code receives a message, its message event handler can call console. See the next section. On Mac and Linux, launching Chrome from a terminal makes stderr and stdout appear in that terminal. This variable is set to stderr by default; you can redirect these messages to an output file by setting the variable as follows:.

You can log all Pepper calls your module makes by passing the following flags to Chrome on startup:. The enable-logging flag tells Chrome to log the calls to stderr. If you develop on a Windows platform you can use the Native Client Visual Studio add-in to write and debug your code. The add-in defines new project platforms that let you run your module in two different modes: As a Pepper plugin and as a Native Client module.

When running as a Pepper plugin you can use the built-in Visual Studio debugger. When running as a Native Client module Visual Studio will launch an instance of nacl-gdb for you and link it to the running code.

If you want to use GDB to debug a program that is compiled with the PNaCl toolchain, you must have a copy of the pexe from before running pnacl-finalize.

The pnacl-finalize tool converts LLVM bitcode to the stable PNaCl bitcode format, but it also strips out debug metadata, which we need for debugging. The actual extension should not matter, but it helps distinguish between the two types of files. Note unlike the finalized copy of the pexe, the non-finalized debug copy is not considered stable. If the version of the debug bitcode pexe does not match that of Chrome then the translation process may fail, and you will see an error message in the JavaScript console.

Also, make sure you are passing the -g compile option to pnacl-clang to enable generating debugging info. Once the debug version is loaded, you are ready to run nacl-gdb. One reason to avoid publishing the debug URL is that it is only guaranteed to work for the Chrome version that matches the SDK version. Developers who may have left the --enable-nacl-debug flag turned on may end up loading the debug copy of your application which may or may not work, depending on their version of Chrome.

If you want to use GDB to debug a program that is compiled with the PNaCl toolchain, you must convert the pexe file to a nexe. You can skip this step if you are using the GCC toolchain, or if you are using pepper 35 or later. Secondly, use pnacl-translate to convert your pexe to one or more.

For this, use the non-finalized pexe file produced by pnacl-clang , not the pexe file produced by pnacl-finalize. The latter pexe has debugging info stripped out.

The option --allow-llvm-bitcode-input tells pnacl-translate to accept a non-finalized pexe. Replace the nmf manifest file that points to your pexe file with one that points to the nexe files. For the example nexe filenames above, the new nmf file would contain:.

Before you start using nacl-gdb, make sure you can build your module and run your application normally. This will verify that you have created all the required application parts. The instructions below assume that you are using a local server to run your application; one benefit of doing it this way is that you can check the web server output to confirm that your application is loading the correct resources. However, some people prefer to run their application as an unpacked extension, as described in Running Native Client Applications.

Compile your module with the -g flag so that your. Launch a local web server e. Launch Chrome with these three required flags: You may also want to use some of the optional flags listed below. A typical command looks like this:. Enables Native Client for all applications, including those that are launched outside the Chrome Web Store. Turns off the Chrome sandbox not the Native Client sandbox. This enables the stdout and stderr streams, and lets the debugger connect.

Specifies the user data directory from which Chrome should load its state. You can specify a different user data directory so that changes you make to Chrome in your debugging session do not affect your personal Chrome data history, cookies, bookmarks, themes, and settings.

Specifies a set of debug mask patterns. This allows you to selectively choose to debug certain applications and not debug others. For example, if you only want to debug the NMF files for your applications at https: This helps prevent accidentally debugging other NaCl applications if you like to leave the --enable-nacl-debug flag turned on. The pattern language for the mask follows chrome extension match patterns. The pattern set can be inverted by prefixing the pattern set with the!

Specifies the URL Chrome should open when it launches. Chrome will start loading the application, then pause and wait until you start nacl-gdb and run the continue command. Go to the directory with your source code, and run nacl-gdb from there. Tells the debugger how to connect to the debug stub in the Native Client application loader. This connection occurs through TCP port note that this port is distinct from the port which the local web server uses to listen for incoming requests, typically port If you are debugging multiple applications at the same time, the loader may choose a port that is different from the default port.

See the Chrome task manager for the debug port. For PNaCl, this provides a convenient way to access the nexe that is a result of translating your pexe. Normally, the IRT is located in the same directory as the Chrome executable, or in a subdirectory named after the Chrome version. You can use a forward slash to separate directories on Linux, Mac, and Windows.

If any directories in the path have spaces in their name, you must put quotation marks around the path. To save yourself some typing, you can put put these nacl-gdb commands in a script file, and execute the file when you run nacl-gdb, like so:.

If nacl-gdb connects successfully to Chrome, it displays a message such as the one below, followed by a gdb prompt:. Once nacl-gdb connects to Chrome, you can run standard gdb commands to execute your module and inspect its state. Some commonly used commands are listed below. See the gdb documentation for a comprehensive list of gdb commands. Note that you can abbreviate most commands to just their first letter b for break, c for continue, and so on.

Native Client Modules

If you want to use GDB to debug a program that is compiled with the PNaCl toolchain, you must have a copy of the pexe from before running pnacl-finalize. Tells the debugger how to connect to the debug stub in the Native Client application loader. Native Client Modules This document describes the classes and functions that you need to implement in a Native Client module in order for Chrome to load, initialize, and run it. The instructions below assume that you are using a local server to run your application; one benefit of doing it this way is that you can check the web server output to confirm that your application is loading the correct resources.

You can specify a different user data directory so that changes you make to Chrome in your debugging session do not affect your personal Chrome data history, cookies, bookmarks, themes, and settings. Native Client is an open-source project, though, and other browsers like Firefox and Internet Explorer could implement NaCl if they wanted to — but the chances of that happening are very, very slim. The code excerpt also shows the initialization of three additional interfaces which are not required: Enables Native Client for all applications, including those that are launched outside the Chrome Web Store.
