Creating Custom Events That Can Pass Data
if you peruse nsdomclassinfoclasses.h you'll see of list of macros of the form domci_class(foo).
...mozilla/dom/src/base/nsdomclassinfo.cpp mozilla contains many convenience macros to make changes like the one you're making easier.
... your modification of this file is basically just two macro calls.
...use nsdomevent.h's ns_forward_to_nsdomevent macro so that you don't have to forward manually (unless you plan on overriding one of nsdomevent's original functions).

Gecko Logging
lazyloglodule provides a conversion operator to logmodule* and is suitable for passing into the logging macros detailed below.
... #include "mozilla/logging.h" static mozilla::lazylogmodule sfoolog("foo"); logging interface a basic interface is provided in the form of 2 macros and an enum class.
... mozilla logging macros moz_log(module, level, message) outputs the given message if the module has the given log level enabled.
... you can set an overall logging level, though it could be quite verbose: set rust_log="debug" you can also target individual modules by path: set rust_log="style::style_resolver=debug" for linux/macos users, you need to use export rather than set.

Localizing with Mercurial
mercurial allows localizers to work locally (on their machines) and then push (an hg term) changes to a remote repository, which usually is hosted on the mozilla servers (hg.mozilla.org).
... mercurial on mac osx installing hg on mac osx is super easy.
... you can install mercurial via macports through the terminal, like so: $ sudo port install mercurial you can also install it by downloading the dmg package from the hg download page.
... more details for more details on installing hg on mac osx, refer to the instructions on mercurial's download page.

Localization prerequisites
on mac and linux, you should be just fine, and on windows, mozillabuild should get you everything you need.
...you can try one of these: notepad++ or notepad2 on windows, vim, gedit or kate on gnu/linux, bbedit on mac os x.
...linux users should know, on the mac, you find terminal in applications/utilities.
...let’s try our entry points: $ hg --version mercurial distributed scm (version 1.3.1) copyright (c) 2005-2009 matt mackall <mpm@selenic.com> and others this is free software; see the source for copying conditions.

dtrace
dtrace is a powerful mac os x kernel instrumentation system that can be used to profile wakeups.
... sudo dtrace -n 'mach_kernel::wakeup { @[ustack()] = count(); }' -p $firefox_pid > $output_file let's break that down further.
... the -n option combined with the mach_kernel::wakeup selects a probe point.
... mach_kernel is the module name and wakeup is the probe name.

tools/power/rapl
these are machine-wide estimates, so if you want to estimate the power consumption of a single program you should minimize other activity on the machine while measuring.
... mac on mac, rapl can be run as follows.
...note that if you do change this file, its contents may reset when the machine is next rebooted.
... combining with powermetrics on mac, you can use the mach power command to run rapl in combination with powermetrics in a way that gives the most useful summary measurements for each of firefox, chrome and safari.

Linked Lists

NSPR Types
for information on naming conventions for nspr types, functions, and macros, see nspr naming conventions.
...since the types (long long versus struct longlong) are not type compatible, nspr defines macros to manipulate 64-bit numeric fields.
... these macros are defined in prlong.h.
... conscientious use of these macros ensures portability of code to all the platforms supported by nspr and still provides optimal behavior on those systems that treat long long values directly.

PR_ASSERT
syntax #include <prlog.h> void pr_assert ( expression ); parameters the macro has this parameter: expression any valid c language expression that evaluates to true or false.
... returns nothing description this macro evaluates the specified expression.
...the macro converts the expression to a string and passes it to pr_assert, using file and line parameters from the compile-time environment.
... this macro compiles to nothing if compile-time options are not specified to enable logging.

Troubleshooting XPCOM components registration
note that even your version of msvc may matter; your test machine may not have the c runtime libraries (msvcr70.dll / msvcp70.dll for msvc 7.0, and similarly named files for 7.1 and 8.0) available.
... this even means that if you are using a component stub, the stub needs to be compiled using a version which the machine does support; most likely this means msvc 6.0.
... if you compiled the component with msvc 8.0 (2005) and are attempting to use it on a windows xp machine or later, it will need a manifest embedded to find the runtime.
... mac-specific hints use ktrace to see if firefox is trying to load your components.

such a cast can easily by-pass nscomptrs machinery, causing leaks, type mismatches, and other calamities.
... // old-style c/c++ casts by-pass |nscomptr|s machinery and cause leaks...
...implementation details and debugging machinery although it is a class, nscomptr has no virtual methods, and therefore, no vtable or vptr.
...in fact, if you used the ns_release macro, p would be null by the time you got to the getnext call.

The Valgrind Test Job
it also works on mac, though sometimes not as well.
... mach valgrind-test see also the general instructions for using valgrind with mozilla code.
... when running locally, you may see errors that do not occur on the test machines.
... errors in system libraries can generally be ignored, because they are out of our control and the kind of thing we suppress on the test machines.

Using the Mozilla symbol server
replace c:\users\bsmedberg\symbols with an appropriate cache directory on your machine.
... symchk: failed files = 4 symchk: passed + ignored files = 179 downloading symbols on linux / mac os x if you are on linux and running gdb 7.9 or newer, you can use this gdb python script to automatically fetch symbols.
...if you want to reload symbols, you can try: nosharedlibrary sharedlibrary lib on older gdb and mac os x there is a python script to download symbols from the mozilla symbol server for gdb, shark and other software that uses symbols.
...the platform is either 'darwin' (for mac) or 'linux'.

Using js-ctypes
on windows, for example, you might load the system user32 library like this: var lib = ctypes.open("user32.dll"); on mac os x, you can load the core foundation library from the core foundation framework like this: var corefoundation = ctypes.open("/system/library/frameworks/corefoundation.framework/corefoundation"); the returned object is a library object that you use to declare functions and data types for use with the loaded library.

<input type="button"> - HTML: Hypertext Markup Language
a simple button we'll begin by creating a simple button with a click event handler that starts our machine (well, it toggles the value of the button and the text content of the following paragraph): <form> <input type="button" value="start machine"> </form> <p>the machine is stopped.</p> const button = document.queryselector('input'); const paragraph = document.queryselector('p'); button.addeventlistener('click', updatebutton); function updatebutton() { if (button.value === 'start machine'...
...) { button.value = 'stop machine'; paragraph.textcontent = 'the machine has started!'; } else { button.value = 'start machine'; paragraph.textcontent = 'the machine is stopped.'; } } the script gets a reference to the htmlinputelement object representing the <input> in the dom, saving this refence in the variable button.

eval() - JavaScript
if you run eval() with a string that could be affected by a malicious party, you may end up running malicious code on the user's machine with the permissions of your webpage / extension.
... additionally, modern javascript interpreters convert javascript to machine code.
...thus, any use of eval() will force the browser to do long expensive variable name lookups to figure out where the variable exists in the machine code and set its value.
... additonally, new things can be introduced to that variable through eval() such as changing the type of that variable, forcing the browser to re-evaluate all of the generated machine code to compensate.

Getting started with Svelte - Learn web development
if you're using windows, you will need to install some software to give you parity with unix/macos terminal in order to use the terminal commands mentioned in this tutorial.
... svelte also provides an online repl, which is a playground for live-coding svelte apps on the web without having to install anything on your machine.
... it's the easiest way to start playing with svelte from any machine, without having to install anything.

Package management basics - Learn web development
for example, if your project relied on webpack with a certain configuration, you'd want to ensure that if you installed that project on another machine or returned to it much later on, the configuration would still work.
...you'll see that npm has added a new field, dependencies: "dependencies": { "parcel-bundler": "^1.12.4" } this is part of the npm magic — if in future you move your codebase to another location, on another machine, you can recreate the same set up by running the command npm install, and npm will look at the dependencies and install them for you.
...whilst the tooling is on our machine, we can ask the software to inspect our use of the code and only include the functions that we're actually using in production — a process known as "tree shaking".

Accessible Toolkit Checklist
on mac os x, ctrl+space is used to bring up the context menu.
...on mac os x, ctrl+space is used to bring up the context menu.
... mac os x difference: option+left and option+right should do deep expand/collapse mac os x difference: user should be able to select multiple rows and expand them with one keystroke.

Adding a new event
all messages are defined by macro in "messages" section of basicevents.h.
... use ns_event_class macro for adding it.
... the macro takes two arguments, aprefix and aname.

Chrome registration
for example, a theme may wish to adopt a different look on mac os x 10.5 than 10.4: osversion>=10.5 abi if a component is only compatible with a particular abi, it can specify which abi/os by using this directive.
...these packages contain three different sets of files, for windows and os/2, macintosh, and unix-like platforms.
... to indicate that a package is platform-specific, add the "platform" modifier to the "content" line after the path, for example: content global-platform jar:toolkit.jar!/toolkit/content/global-platform/ platform once that is specified in your manifest you then ensure that under the directory global-platform are subdirectories win (windows/os2), mac (os9/osx), or unix (everything else).

Command line options
enter the following command: firefox -profilemanager mac os x go to applications > utilities.
... open terminal and enter the following command: cd /applications/firefox.app/contents/macos ./firefox -profilemanager if you use firefox nightly, you can enter: cd /applications/firefoxnightly.app/contents/macos ./firefox -profilemanager linux open terminal and enter the following command: cd thunderbird installation directory ./thunderbird -profilemanager the example above invokes the "-profilemanager" command line option with mozilla's thunderbird mail client.
... note: on mac os x specifying a relative path is not supported anymore from firefox 4.0 and up due to a regression, see bug 673955.

Debugging
debugging mozilla with gdb gdb is our primary debugger on mac and linux.
... debugging mozilla with lldb lldb is the new debugger on mac.
... debugging mozilla with valgrind valgrind is a memory debugger for mac and linux.

How Mozilla's build system works
for many developers, typing mach build to build the tree is sufficient to work with the source tree.
... phases when you type mach build to build the tree, three high-level phases occur within the build system: system detection and validation preparation of the build backend invocation of the build backend phase 1: configure phase 1 centers around the configure script.
...to view the variables and functions available in your checkout of the tree, run the following: mach mozbuild-reference or, you can view the raw file at /python/mozbuild/mozbuild/frontend/context.py.

ESLint
setting up eslint ./mach eslint --setup running eslint eslint can be run via: ./mach lint -l eslint you can limit running it to a specific directory with: ./mach lint -l eslint browser/components or work directory changes: ./mach lint -l eslint -w or outgoing commits only: ./mach lint -l eslint -o see ./mach eslint --help for more options when running eslint.
... more information: outline details of the rules rule source code common issues and how to solve them my editor says that "mozilla/whatever" is unknown run ./mach eslint --setup restart your editor if that doesn't work, check that you have your editor pointing to the correct node_modules folder.
... for example: in windows 10, if you have installed node.js on "c:\nodejs", then the command should look like: export path=$path:/c/nodejs enabling eslint for a new directory remove the directory from .eslintignore (in the base directory of the repository) fix errors that occur when running ./mach eslint path/to/dir, see also the no-undef rules below.

JavaScript OS.Constants
macuserlibdir the path to the user's library directory.
... maclocalapplicationsdir the path to the local applications directory.
...useful mostly for using js-ctypes to interact with the following platforms: macos x; android; linux; other variants of unix.

Bootstrapping a new locale
hg allows localizers to work locally on their machines and then "push" changes to their official mozilla repository.
... installing mercurial depending on your operating system, you will need to install the correct version of hg on your machine.
...you can choose to use: notepad++ or notepad2 on windows, vim, gedit or kate on gnu/linux, textwrangler on mac os x.

Localizing with Mozilla Translator
a bit of history on mt mt has been evolving from long ago, when l10n were done always on shipped en-us jars and when mozilla suite had five l10n jars: ab-cd.jar, ab-win.jar, ab-mac.jar, ab-unix.jar, and cd.jar.
... mt thus referred to ab-cd.jar contents as ''platform neutral'' platform, cd.jar as '''region''' platform (or regional files), and the other three as ''windows platform'', ''mac platform'' and ''unix platform''.
... if you are using a filesystem with symbolic links support (i.e., linux or mac), you can create symbolic links in a separate directory so it contains just the locale part.

Localizing with Pontoon
translation helpers as you can see, suggestions from history, translation memory, machine translation and other locales are also available in the out-of-context translation panel.
... machinery displays matches from various services: internal translation memory, mozilla transvision, open source translation memory, microsoft terminology and machine translation.
... search almost like machinery, but takes provided keyword as input parameter instead of the original string.

Intel Power Gadget
on mac and linux, tools/power/rapl is probably a better tool to use.
... understanding the power gadget output the following screenshot (from the mac version) demonstrates the available measurements.
... (an energia dashboard can be seen here; please note that the data has not been updated since early 2014.) version 3.0 (available on mac and windows, but not on linux) also exposes an api from which the same measurements can be extracted programmatically.

Leak-hunting strategies and tips
(or allocations?) all tier 1 platforms build with --enable-trace-malloc leak tools for simple objects and summary statistics tracemalloc all allocations all tier 1 platforms build with --enable-trace-malloc valgrind all allocations mac, linux build with --enable-valgrind and some other options lsan all allocations mac, linux any build apple tools ?
... mac any build leak tools for debugging memory growth that is cleaned up on shutdown diffbloatdump (part of tracemalloc) all allocations linux only?
...it may just involve setting the xpc_shutdown_heap_dump environment variable to a file name, but i haven't tested that.) post-processing of stack traces on mac and linux, the stack traces generated by our internal debugging tools don't have very good symbol information (since they just show the results of dladdr).

Profiling with the Firefox Profiler
there are os-specific waiting functions like ntwaitformultipleobjects seen in the example above taken on windows or mach_msg_trap on macos.
... install the latest pre-release build in your host machine's firefox browser that has your phone reachable via adb.
... tagging is done by adding macros of the form auto_profiler_label("namespace", "name").

Profiling with the Gecko Profiler and Local Symbols on Windows
in the past you had to need to run mach buildsymbols manually, but this is no longer needed.
...using ./mach build.
... generate the breakpad symbol files by running ./mach buildsymbols: https://developer.mozilla.org/en/building_firefox_with_debug_symbols#breakpad_symbol_files this will have created symbols under $objdir/dist/ , named after the binary name, architecture and version, so something like "firefox-40.0a1.en-us-win32.crashreporter-symbols.zip" point talos to this zipfile by passing its path to the --symbolspath flag.

Refcount tracing and balancing
xpcom_mem_alloc_log for platforms that don't have stack-crawl support, xpcom supports logging at the call site to addref/release using the usual cpp __file__ and __line__ number macro expansion hackery.
...for example: env xpcom_mem_log_classes=nsdocshell xpcom_mem_refcnt_log=./refcounts.log ./mach run this will log the addref and release calls only for instances of nsdocshell while running the browser using mach, to a file refcounts.log.
...for example, env xpcom_mem_log_classes=nsdocshell xpcom_mem_log_objects=2 xpcom_mem_refcnt_log=./refcounts.log ./mach run will log stack traces to refcounts.log for the 2nd nsdocshell object that gets allocated, and nothing else.

TraceMalloc
this example is for macos; small modifications are needed for other platforms.
...build/dist/minefield.app/contents/macos/firefox --trace-malloc /dev/null --shutdown-leaks=sdleak.log # convert raw log to text representation of call trees perl source/tools/trace-malloc/diffbloatdump.pl --depth=15 --use-address /dev/null sdleak.log > sdleak.tree.raw # frobulate trees to remove extraneous junk perl source/tools/rb/fix-macosx-stack.pl sdleak.tree.raw > sdleak.tree you can also use the leakstats program to analyze a log for shutdown leaks.
...(this can be done by examining the unprocessed output of an xpcom_mem_refcnt_log, one of the nstracerefcnt logs.) you should use the --use-address argument to diffbloatdump.pl, and then the diff tree can be run through fix_linux_stack.py or fix_macosx_stack.py as needed.

Profile Manager
system requirements: mac: an intel processor, i386 or x86_64 linux: any version capable of running firefox 4.0 windows: xp or later source code you can download the source as well: hg clone http://hg.mozilla.org/automation/profilemanager/ instructions for building can be found in build.txt.
... starting profile manager to start profile manager, just launch profilemanager.exe (on windows) or profilemanager-bin (on linux and mac).
... profile manager does not track these backups in the ui, but using profile archives is an easy way to move profiles between machines.

McCoy
mccoy-0.5.en-us.win32.zip (windows) mccoy-0.5.en-us.linux-i686.tar.bz2 (linux) mccoy-0.5.en-us.mac.dmg (mac os x universal) there are some known issues with running mccoy on linux.
... backing up data if you need to backup your data or move it from one machine to another you need to take a copy of the profile folder.
... this is located in: %appdata%\mozilla\mccoy (windows) ~/.mozilla/mccoy (linux) ~/library/application support/mccoy (mac os x) it is highly recommended that you back up your profile folder and store it in a safe location whenever you create a new key; without a backup, there is no way to recover your private keys if they are lost!

Creating a Cookie Log
run firefox by typing "./firefox" and pressing enter mac os x open terminal.app, which is located in the /applications/utilities folder (these instructions are for bash, the default shell in mac os x 10.3 and higher; if you use something else, you probably know how to modify these instructions already).
...type "cd /applications/firefox.app/contents/macos" and press return.
...it should be in c:\temp on windows, your home directory on linux, or the desktop on mac os x.

Introduction to NSPR
the current implementation of nspr allows developers to compile a single source code base on macintosh (ppc), win32 (nt 3.51, nt 4.0, win'95), and over twenty versions of unix.
... nspr naming conventions naming of nspr types, functions, and macros follows the following conventions: types exported by nspr begin with pr and are followed by intercap-style declarations, like this: print, prfiledesc function definitions begin with pr_ and are followed by intercap-style declarations, like this: pr_read, pr_jointhread preprocessor macros begin with the letters pr and are followed by all uppercase characters separated with the underscore character (_), like this: pr_bytes_per_short, pr_extern nspr threads nspr provides an execution environment that promotes the use of lightweight threads.
... some operating systems cannot be made preemptable (for example, mac os and win 16).

Logging
nspr also provides "assert"-style macros and functions to aid in application debugging.
... conditional compilation and execution log types and variables logging functions and macros use example conditional compilation and execution nspr's logging facility is conditionally compiled in and enabled for applications using it.
... log types and variables two types supporting nspr logging are exposed in the api: prlogmoduleinfo prlogmodulelevel two environment variables control the behavior of logging at execution time: nspr_log_modules nspr_log_file logging functions and macros the functions and macros for logging are: pr_newlogmodule pr_setlogfile pr_setlogbuffering pr_logprint pr_logflush pr_log_test pr_log pr_assert pr_assert pr_static_assert (new in nspr 4.6.6xxx this hasn't been released yet; the number is a logical guess) pr_not_reached use example the following sample code fragment demonstrates use of the logging and debugging aids.

Memory Management Operations
this chapter describes the global functions and macros you use to perform memory management.
... memory allocation functions memory allocation macros memory allocation functions nspr has its own heap, and these functions act on that heap.
... memory allocation macros macro versions of the memory allocation functions are available, as well as additional macros that provide programming convenience: pr_malloc pr_new pr_realloc pr_calloc pr_newzap pr_delete pr_freeif ...

NSPR Error Handling
error type error functions error codes for information on naming conventions for nspr types, functions, and macros, see nspr naming conventions.
... pr_end_of_file_error unexpectedly encountered end of file (mac os only).
... pr_file_seek_error an unexpected seek error (mac os only).

PR_LOG
_args); parameters the macro has these parameters: _module a pointer to a log module structure.
... returns nothing description this macro formats the specified arguments and writes the output to the log file, if logging is enabled for the specified module and level.
... this macro compiles to nothing if compile-time options are not specified to enable logging.

PR_NOT_REACHED
syntax #include <prlog.h> void pr_not_reached(const char *_reasonstr); parameters the macro has this parameter: reasonstr a string that describes why you should not have reached this statement.
... returns nothing description this macro writes the specified reason string to the log and terminates the application.
... this macro compiles to nothing if compile-time options are not specified to enable logging.

PR_STATIC_ASSERT
syntax #include <prlog.h> pr_static_assert ( expression ); parameters the macro has this parameter: expression any valid expression which evaluates at compile-time to true or false.
... returns nothing description this macro evaluates the specified expression.
... this macro may only be used in locations where an extern function declaration may be used.

... when gdb comes up, enter set annot 1 to get it to emit file location information so that emacs will pop up the corresponding source.

64-bit Compatibility
the best way to fix this is to make types explicit, such as: const uintptr_t pointer_tagbits = 3 or by using a cast inside the macro.
...for example, this code will not load a native integer correctly on a 64-bit machine: struct object { void *data; }; lir->insload(lir_ld, objins, ins->insimm(offsetof(object, data))); lir_ld is 32-bit.
... on 64-bit machines you must use lir_ldq.

JSFastNative

... examples of xul applications: firefox - web-browser thunderbird - email client seamonkey - web-browser, advanced e-mail and newsgroup client, irc chat client, and html editing made simple sunbird - cross-platform calendar application kompozer - a complete web authoring system for linux desktop, microsoft windows and macintosh users to rival programs like frontpage and dreamweaver.
... mac platform we currently support only a subset of universal access.

Finishing the Component
at the same time, you can add the macro ns_decl_nsicontentpolicy to the class declaration that provides all of the methods defined in the interface nsicontentpolicy.
... the updated weblock class looks as follows: class weblock: public nsiobserver, public iweblock, public nsicontentpolicy { public: weblock(); virtual ~weblock(); ns_decl_isupports ns_decl_nsiobserver ns_decl_iweblock ns_decl_nsicontentpolicy private: urlnode* mrooturlnode; prbool mlocked; }; remember to change the nsisupports implementation macro to include nsicontentpolicy so that other parts of gecko will know weblock supports the nsicontentpolicy interface without modifying this macro.
... the name of the machine hosting the resource.

NS_ADDREF
summary macro addrefs the argument.
...ns_addref(foo) is equivalent to foo->addref(); this macro exists mainly for historical reasons, but for consistency and for symmetry with ns_release it should still be used.

NS_ERROR
summary macro throws a assertion (ns_assertion) with the text "error: (error text)", so writes this text to console (stderr) and to debug logs (nspr logging).
... this macro is meant for critical errors; like assertions, ns_errors should not be reachable.

NS_IF_ADDREF
summary macro addrefs the argument, if it is non-null.
...only use this macro if the pointer might be null; use ns_addref otherwise.

NS_RELEASE
summary macro decrements the reference count of a pointer by one.

WebGLRenderingContext - Web APIs
the webgl rendering context is an interface, through which you can set and query the state of the graphics machine, send data to the webgl, and execute draw commands.
... saving the state of the graphics machine within a single context interface is not unique to webgl.

Clearing with colors - Web APIs
this is why webgl/opengl is often called a state machine.
... by tweaking those "dials" and "switches" you can modify the internal state of the webgl machine, which in turn changes how input (in this case, a clear command) translates into output (in this case, all pixels are set to green).

Color masking - Web APIs
this is an important aspect of the webgl state machine.
... finally, color masking teaches us that webgl is not only a state machine, it is also a graphics pipeline.
