Previously, running |mach doc <subtree>| would use whatever conf.py file
happened to live in the subtree. For example, running:
./mach doc tools/lint
Would build with tools/lint/docs/conf.py. This is bad because it means the
generated docs will look different from the docs that eventually will be

This patch makes sure we always use tools/docs/conf.py for building, even when
only generating a subtree.
Furthermore, this sets things up such that when you modify a file, only the
subtree containing the modified file will be re-generated. This cuts down
rebuild times from ~2 minutes to ~20 seconds.
There is one caveat. When rebuilding a subtree, the index of other trees will
be overwritten in that particular subtree. I couldn't figure out anyway around
this. This tradeoff for *much* faster rebuild times seems worth it.

LUL::mAdminThreadId is used only to assert that certain calls into the LUL
object are made on the correct thread. Because those assertions are done
using MOZ_ASSERT, some compilers spot that LUL::mAdminThreadId is unused in
non-debug builds, emit a warning to that effect, and then cause the build to
fail due to the presence of -Werror.
Given that (1) it's unlikely that people will use the profiler in debug
builds, (2) failure of these assertions is likely to lead to deadlocking or
crashing in the profiler, and (3) they don't occur on high-frequency paths,
a good solution seems to be to convert them to MOZ_RELEASE_ASSERTs, hence
causing LUL::mAdminThreadId to be used in even in non-debug builds.
In some cases, related MOZ_ASSERTs relating to LUL::mAdminMode have also
been upgraded to MOZ_RELEASE_ASSERTs, for consistency with the
LUL::mAdminThreadId changes.

This changes the default to opening a livereload webserver after doc generation
(as opposed to opening the index file). Any changes to the specified path will
result in a rebuild and refresh of the browser.
For example, if you run:
./mach doc tools/lint
The linting docs will be built, served and opened in a browser. Modifying any
file under 'tools/lint/docs' will refresh the browser with your changes.
To disable this behaviour and simply open the index file, you can pass in
'--no-serve'. The '--no-open' flag will continue to work (both with http and
the file system).
One caveat to this patch is that when generating the root docs (by running
|mach doc|), we don't watch all possible doc paths (just the root one under
'tools/docs/'). This will probably be fixed in the follow-up bug 1454640.

This removes the ability to specify multiple doc paths at the same time with
|mach doc|. We will be changing the default from opening index files to serving
the documentation with a webserver. Supporting multiple doc roots would mean
spinning up multiple servers in different threads.
This would add a lot of complexity for a feature which I don't think is very
useful. It's very rare that one would need to edit more than one doc location
at the same time. And if this is ever needed, the developer can just build the
entire doctree (by running |mach doc|) or run |mach doc <path>| in multiple
different terminals.

return quickly and gracefully. This way the hook process itself will not abort, just
the linting. After hitting Ctrl-C, the vcs operation should continue as if the lint

Enables |./mach try fuzzy --talos-profile|. This template only applies to talos
tasks. It also provides --geckoProfile for consistency with |mach try syntax|,
but I don't like this name so it's hidden from the help.
The 'talos-profile.yml' template is also very specific (only applies to Talos
tasks). Ideally I'd like a general 'command.yml' template that just appends
arguments to the command for any arbitrary tasks. But then we'd need to invent
an expression syntax in try_task_config.json so we could make sure it only
applies to Talos. Then I thought rather than implement it for a specific
template, we should have a general way of doing this which could apply to any
and all of the templates.
Needless to say, it's a rabbit hole and something that's best left to a
follow-up so we don't delay this bug.

There a few pieces needed here to properly handle KeyboardInterrupts.
1. All in-progress work needs to abort. Ideally the underlying linters will be
able to catch KeyboardInterrupt, and return partial results (like the flake8
linter does). Linters may alternatively allow the KeyboardInterrupt to
propagate up. Mozlint will catch and handle this appropriately, though any
results found will be lost. The only change to this behaviour was fixing a bug
in the flake8 linter.
2. Any unstarted jobs need to be canceled. In concurrent.futures, there are two
different queues. First, jobs are placed on the work queue, which is just a list
maintained by the parent process. As workers become available, jobs are moved
off the work queue, and onto the call queue (which is a multiprocessing.Queue).
Jobs that live on the work queue can be canceled with 'future.cancel()', whereas
jobs that live on the call queue cannot. The number of extra jobs that are stored
on the call queue is determined by this variable:
https://hg.mozilla.org/mozilla-central/file/deb7714a7bcd/third_party/python/futures/concurrent/futures/process.py#l86
In this patch, the parent process' sigint handler (which will be called on Ctrl-C)
is responsible for canceling all the jobs on the work queue. For the jobs on the
call queue, the best we can do is set a global variable that tells workers to
abort early.
3. Idle workers should exit gracefully. When there are no more jobs left, workers
will block on the call queue (either waiting for more jobs, or waiting for the
executor to send the shutdown signal). If a KeyboardInterrupt is received while a
worker is blocking, it isn't possible to intercept that anywhere (due to quirks
of how concurrent.futures is implemented). The InterruptableQueue class was
created to solve this problem. It will return None instead of propagating
KeyboardInterrupt. A None value will wake the worker up and tell it to gracefully
shutdown. This way, we avoid cryptic tracebacks in the output.
With all of these various pieces solved, pressing Ctrl-C appears to always exit
gracefully, sometimes even printing partial results.

This essentially tests tools/lint/python/flake8.py. Though it also adds
a basic framework for testing all the other linters as well. Getting this
added now will allow others to collaborate on adding more tests without
needing to get to 100% coverage for all linters right off the bat.
All python tests under tools/lint/test will run as part of the 'ml' task
on Linux, and the build task on Windows (OSX coverage is currently missing
for python tests).
The flake8 linter currently has a bug where the 'exclude' argument is

(generated by cd mingw-w64/mingw-w64-headers &&
find . -name "*.h" | xargs -I bob -- basename bob | sort | uniq)
and will alert if they are in an #include statement but not
all-lowercase.

console.assert keeps the same semantics as NS_ASSERT in that it doesn't throw an exception,
but a lot of the places code was using it in a way that would be better served by throwing
an exception when the condition is false.

This changeset changes behavior.
If the profile is streamed before any JSContext has gone away, we now iterate
over the entire buffer twice (per thread): First, to collect information about
JIT frames, and then again when we build the JSON for the samples. The first
traversal stores small pieces of JSON for JIT fromes in individual strings, and
the second iteration splices those strings into the thread JSON's frame table.
When the JSContext for a thread goes away, we no longer build JSON for samples,
and we don't reset the profiler buffer. We now only build the JSON for JIT
frames. Once the complete profile is requested and we build samples for it, we
iterate over the entire buffer, and look up the cached JIT frame information for
JitReturnAddr entries from the correct range. Different parts of the buffer may
correspond to the life time of different JSContexts: For each JSContext we will
have one range in the JITFrameInfo, and we can look up the correct range based
on the buffer position of the JitReturnAddr entry that we're processing.
This new way of doing things has multiple advantages:
- We no longer reset the buffer, so we no longer lose information about other
threads.
- All threads from a given process now always have sample data for the same
time range. Before this change, the "partial profile" from a thread that
lost its JSContext could extend further into the past than the other threads'
profiles.
- Requesting profiles multiple times now has more consistent results. Before
this change, the first requested profile would include the partial profile,
but then the partial profile was discarded. And the second requested profile
would not contain any data for the time before the JSContext went away.
- We now do less work when a thread's JSContext goes away. This should
decrease the interruption time.

In an upcoming patch we'll want to initialize mUniqueStrings by stealing
another object's UniqueJSONStrings, but UniqueJSONStrings itself is not
move-constructible. But UniquePtr is.
Making UniqueJSONStrings itself move-constructible would be a bit tricky
because it has a SpliceableChunkedJSONWriter which is not move-constructible;
and making SpliceableChunkedJSONWriter move-constructible is hard because
there's no obvious "empty but valid" state that we could leave a moved-out-of
SpliceableChunkedJSONWriter in; for example, it expects to have a non-null
WriteFunc at all times.

I think this file was picking up such a declaration from a different file
already, through unified builds.

nsCString is the idiomatic string class we want to use anyway. There's no need

The file copies and renames make this patch look a bit confusing. Here's what
happens:
ThreadInfo.h:
Most of the code gets moved into RegisteredThread.h and ProfiledThreadData.h,
but a small piece remains in ThreadInfo.h.
ThreadInfo.cpp:
Gets split into RegisteredThread.cpp and ProfiledThreadData.cpp.
ThreadInfo.cpp itself goes away.
In the mercurial changeset, I've marked ThreadInfo.h as being copied to both
RegisteredThread.h and to ProfiledThreadData.h, and ThreadInfo.cpp as being
copied to RegisteredThread.cpp and as being renamed to ProfiledThreadData.cpp.

The overlay elements with children of editMenuOverlay.xul are moved into
include files (editMenuCommands.inc.xul and editMenuKeys.inc.xul). For
the other single elements in the overlay, the attributes are inlined
wherever they are used.

As of Bug 1425463 it's available in all contexts (including JSM). The following
