Running old extensions with newer versions of Mercurial may crash `hg`
due to the old extension accessing something or doing something that has
been changed in the new release.
To minimize the risk of this happening, we disable common 3rd party
extensions when cloning or pulling as part of `mach mercurial-setup`. We
don't want to disable everything because some extensions (like
remotenames) provide features the user may want enabled as part of the
clone/update. This leaves the door open for more failures. Hopefully
this approach is sufficient. We can always revisit later.
This can speed up performance significantly.
Only support OS X for now because on Linux we have to adjust inode
limits to support mozilla-central and I don't feel like scope bloating.
bundleclone is the Mozilla-specific precursor to the "clonebundles"
feature in Mercurial 3.6. Change the wizard to recognize when
clonebundles is available and to favor it. Activating clonebundles will
also disable bundleclone, as bundleclone is redundant with clonebundles.
(If both are enabled, bundleclone detects this and gets out of the way.)
Main reason for recommending 3.5 is bundle2. The protocol is faster and
we can do things like put extra data in the server exchange. It also
enables generaldelta to be exchanged without pain.
And of course there are tons of performance improvements and bug fixes.
We need to let ContentParent and PluginModuleParent get a reference to the ProfileGatherer
during the window of time that we're profiling so that if they start to die (the actor is
starting to go away), they have a gatherer they can send their last profile data to.
This makes it clearer that really it's the same thing as FINAL_TARGET,
with preprocessing.
We still keep DIST_FILES in backend.mk because it's shorter and doesn't
really matter.
tools/power/rapl.cpp:844:5 [-Wunreachable-code] code will never be executed
clang reports a -Wunreachable-code warning for sigemptyset() because Darwin's sigemptyset() is a macro that always returns 0. Thus `if (sigemptyset(&sa.sa_mask) < 0)` is always false and `Abort("sigemptyset() failed")` is never called. Linux's sigemptyset() can return 0 or -1. The extra parens around (0) suppress the clang warning.
Now, running |mach doc <path/to/project>| will generate the sphinx based docs of the project and open them
in the default browser. Mulitple doc paths can be supplied at a time. E.g:
./mach doc testing/mozbase
The Read the Docs environment doesn't have SHELL defined. This causes
mach.mixin.process's import to fail, as it insists on finding an active
shell. While we could fix mach.mixin.process to not raise if the
variable is not set, this is a bit more work and has wider build system
and mach implications. So we employ a quick hack instead.
DONTBUILD (NPOTB)
The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.
