clang-cl's system header detection doesn't kick in if we're using full
paths to the STL headers we need to include. And if certain headers
aren't recognized as system headers, we get a pile of warnings from
said headers. Use #include_next to ensure that system headers are
recognized as such, and suppress the warnings.

Now that we compile with cargo, we don't have fine-grained control over
the build flags used via environment variables detected in configure or
set in config.mk. We should just remove that dead code so nobody trips
over it.
This patch is really two separate changes.
The first change is that rust crates are large, standalone entities that
may contain multitudes of source files. It therefore doesn't make sense
to keep them in SOURCES, as we have been doing. Moving to use cargo
will require a higher-level approach, which suggests that we need a
different, higher-level representation for Rust sources in the build
system.
The representation here is to have the build system refer to things
defined in Cargo.toml files as the entities dealt with in the build
system, and let Cargo deal with the details of actually building things.
This approach means that adding a new crate to an existing library just
requires editing Rust and Cargo.toml files, rather than dealing with
moz.build, which seems more natural to Rust programmers. By having the
source files for libraries (and binaries in subsequent iterations of
this support) checked in to the tree, we can also take advantage of
Cargo.lock files.
The second is that we switch the core build system over to building via
cargo, rather than invoking rustc directly.
We also clean up a number of leftover things from the Old Way of doing
things. A number of tests are added to confirm that we'll only permit
crates to be built that have dependencies in-tree.
Through an oversight, we listed librul.a twice when linking libxul: once
as part of the "objects" we were linking, and once as a static library.
This duplication is unnecessary and would cause problems later when we
try to generate librul.a via cargo, as cargo will put it someplace
different from where we expect and the two names will conflict. Let's
have rules.mk be the single source of truth for how librul.a is named,
and then the code to link libxul can simply refer to that name.
The only use of this variable is to override NSINSTALL, and its value is
the same as NSINSTALL_PY.

But its default value on Windows is "link", which can pick /usr/bin/link

use other names. The new implementation searches through the slots from the

Historically, a mozinfo for js standalone build has not been necessary,
but with the move towards a) having things work with mach and b)
buildconfig using the MozbuildObject.from_environment in next patch,
mozinfo becomes necessary (it's required for
MozbuildObject.from_environment to find the directory is an objdir).
Interestingly, hazard builds do both a js standalone build and a desktop
Firefox build at the same time, both of which are done with MOZCONFIG
set in the environment... with the Firefox mozconfig. The result of now
writing a mozinfo for js standalone builds is that in that case, they
end up with a reference to the mozconfig, which the build system then
reads, and finds a MOZ_OBJDIR, which then doesn't match the js
standalone build objdir. So for those builds, reset MOZCONFIG.
Until now, we had some STL headers listed in the system-headers list
such that they would get a system wrapper, but not all of them.
On the other hand, the STL wrappers do the same job as the system
wrappers (applying default visibility), on top of their own, so the
presence of the STL headers in system-headers wasn't making much of a
difference.
Except we have places in the tree where we can't build with STL wrappers
for a number of reasons. And in that case, we *do* need system wrappers
for the STL headers, but we didn't have system wrappers for all of them.
So instead of relying on the STL headers being listed both in
system-headers and stl-headers, concatenate both lists to create the
system wrappers.
Similarly to the considerations about glibc, the Linux compatibility matrix
(https://developer.mozilla.org/en-US/Firefox/Linux_compatibility_matrix)
tells us no distro with Gtk+3 3.4 has a version of libstdc++ older than
4.6.
The data in the matrix doesn't go to that level of detail, but Ubuntu
12.04 LTS, being the only one with version 4.6 (others have at least
4.7), it's worth noting it has version 4.6.3. Which means we can safely
require libstdc++ symbols version 3.4.16 (which were added in 4.6.1).
This will allow us to remove a lot of the stdc++ compatibility hacks.
The requirement for glibc has been set to version 2.7 for a long while.
Spidermonkey uses the pthread_setname_np symbol, which is only available
since glibc 2.12. So far, we've been fortunate that the symbol doesn't
end up in libxul, or tests that link to js directly, because the symbol
is eliminated as being called by effectively dead code.
There are multiple reasons why this is going to change, one of which
being changes to the way things are linked, that will make the linker
not eliminate that code in some cases. Another is that eventually, the
separation of build systems between js and top-level is going to fade,
and the glibc checks, which apply to all gecko binaries, will also apply
to js binaries. They currently are not happening, and would fail because
of pthread_setname_np if they were.
Taking a step back, as of version 46, the mozilla.org builds require at
least Gtk+3 3.4. Which means the requirements for the underlying system
have received a dramatic bump, and it's time to revisit the requirements
for binary compatibility.
I went through all my notes from all the recent times binary compatibility
has been considered, and put together a compatibility matrix on MDN from
that data as well as more recent data that I could find here and there,
about the major non-rolling-release distros (RHEL, Fedora, SuSE, Debian,
Ubuntu)
https://developer.mozilla.org/en-US/Firefox/Linux_compatibility_matrix
Considering the data there, none of the distros that have at least Gtk+3
3.4 have a glibc older than 2.13. The list of symbols that 2.13 provides
that 2.12 doesn't have is not large enough, though, to really care about
depending on 2.13.
This uses a rough form of prefix matching, considering anything that ends in a
path separator and appears as a prefix of a file to be a directory.

The intent in bug 1271829 was to make all the XCFLAGS set in
config/external/nss/Makefile.in accumulate instead of replacing each
other. Unfortunately, there is also an AC_SUBST variable named XCFLAGS,
use for other purposes, and we ended up adding on top of that variable.
Using a different local variable allows to still accumulate the values,
while keeping away from the XCFLAGS from autoconf.mk.
Since the introduction of the STL wrappers, they have included
mozalloc.h, and multiple times, we've hit header reentrancy problems,
and worked around them as best as we could.
Taking a step back, all mozalloc.h does is:
- declare moz_* allocator functions.
- define inline implementations of various operator new/delete variants.
The first only requires the functions to be declared before they are used,
so mozalloc.h only needs to be included before anything that would use
those functions.
The second doesn't actually require a specific order, as long as the
declaration for those functions comes before their use, and they are
either declared in <new> or implicitly by the C++ compiler.
So all in all, it doesn't matter that mozalloc.h is included before the
wrapped STL headers. What matters is that it's included when STL headers
are included. So arrange things such that mozalloc.h is included after
the first wrapped STL header is fully preprocessed (and all its includes
have been included).
It turns out that, since we're including <new> before setting
_GLIBCXX_DEBUG, the debug parts of c++config.h are not activated, and
that has an impact of how much of the debug features of the STL are
activated.
In contrast, the upcoming changes to the STL wrappers are avoiding the
include of <new> before _GLIBCXX_DEBUG is set, which in turn breaks the
build because, as we link things that use STL wrappers with things that
don't, they end up with a different state of STL debugging, and have
mismatching symbols.
This updates the nss build to require SSE2 instructions on win32.
By default nss builds with -arch:IA32 for maximum compatibility.
Firefox 49 dropped support for non-SSE2 platforms, so propagate
that to the nss external build. XCFLAGS come after the nss build's
default settings, and the last -arch switch will override the
previous ones.
Bump CLOBBER because we've had trouble with file removal permission
errors on integration builds.

Our current build system support for Rust compiles any Rust crate into a

libraries generated from C/C++ files), and generates a super-crate,

In contrast to the GNU AS manual, the syntax for the .section directive
uses '%progbits' instead of '@progbits'; at least on ARM. Looking at the
ICU tools and the generated files confirms this.
Multiple people have complained that the build output of printing the
source files being built adds little value. I agree. The extra output
doesn't give really helpful progress info because sources can be built
in non-deterministic order. Furthermore, the extra output hides useful
output like compiler warnings.
This patch makes the default build system output even less verbose. We
no longer print the individual source targets when they are built. We do
still print the targets for binaries, so some sense of progress can be
inferred.
If people like verbosity, they can export the undocumented
BUILD_VERBOSE_LOG environment variable can be set to restore the old

It's an opt-in flag that allows to display where the build is in
terminal window titles. The fact that it's opt-in and likely unknown

the platform has to essentially create a copy of it in the read/write

Before this patch, this would indeed happen for the duration of that run of the

appear to be from the read/write database, and thus was not considered a
built-in root. This patch changes the test of built-in-ness to explicitly
search the built-in certificate slot for the certificate in question. If found,

Our STL wrappers do various different things, one of which is including
mozalloc.h for infallible operator new. mozalloc.h includes stdlib.h,
which, in libstdc++ >= 6 is now itself a wrapper around cstdlib, which
circles back to our STL wrapper.
But of the things our STL wrappers do, including mozalloc.h is not one
that is necessary for cstdlib. So skip including mozalloc.h in our
cstdlib wrapper.
Additionally, some C++ sources (in media/mtransport) are including
headers in an extern "C" block, which end up including stdlib.h, which
ends up including cstdlib because really, this is all C++, and our
wrapper pre-includes <new> for mozalloc.h, which fails because templates
don't work inside extern "C". So, don't pre-include <new> when we're not
including mozalloc.h.

One can run individual tests with python testfile.py Class.method. But
the output for tests only shows the method so looking at a test output
is not enough to tell how to run one particular test. Moreover, there
are many cases where a test file contains multiple classes, and we fail
to identify the difference between those classes.
Python's unittest has decorators to mark tests as skipped or expecting
to fail. Mozunit runner fails to print anything for them.
While here, somehow unify the output for TEST-UNEXPECTED-FAIL.
This leaves known failures silent about the failure. It would be better
to only show them with a flag, like -v, and to leave it to a followup.
Python's unittest separates errors and failures, where the former is
uncaught exceptions and the latter uncaught assertions. We were only
printing the former, making the mozunit runner output useless to debug
failures due to assertions in the code being tested.
I would usually edit the test to temporarily switch to unittest.main().
Enough is enough, handle failures properly.
At the same time, instead of printing all the errors one after the other
at the end, print them right after the TEST-UNEXPECTED-FAIL message.

The flag is used to create .sbr files, which bscmake subsequently uses to
create .bsc files. These files and related tools are, aiui, the ancestors
of Intellisense.
The -FR C*FLAGS are added to the build if MOZ_BROWSE_INFO or MOZ_BSCFILE
are set in the recursive make backend. While the former has an AC_SUBST,
the latter does not, so in practice, only the former can be set by
supported methods, and would need to be set in a mozconfig. At that
rate, people who do want those flags can add them in the C*FLAGS on
their own.
Developers are probably better served by the VisualStudio backend
anyways.
We don't really care to set those in js/src/configure because the JS
engine doesn't use ObjC. We also don't care to preserve the += behavior
because there were no AC_SUBST in the first place, so it's unlikely
anyone has an override in their mozconfig and expects it to work.
FasterMake needs some RecursiveMake install manifests to have been
processed before doing its work, so we can actually end up processing
them twice because of the going back and forth from FasterMake in the
hybrid build system.
Set the dependency at the RecursiveMake level when doing an hybrid
build.

Recent changes in bug 1239217 added the faster backend to the default
build mechanism for artifact builds. This seems to have uncovered a
difference in behavior between GNU Make 3.81 and newer. Starting with
GNU Make 3.82, pattern rules are selected according to shortest stem.
Before, they are used in definition order.
So, we change the order of the pattern rules so the longest prefixes are
first. This should result in the same behavior on various GNU Make
implementations.

The current rule is only for "backend.RecursiveMakeBackend", but, with
the current default of generating both the RecursiveMake and FasterMake
backends, the command creates/refreshes both backends. This is, in fact,
how the FasterMake backend is refreshed in most cases.
Moreover, with an hybrid backends, the generated file is not
"backend.RecursiveMakeBackend" anymore, so we need a more generic way to
handle this.
Furthermore, it's not necessarily desirable for all backends to have a
dependency file to handle the dependencies to refresh the backend, so
generate a plain list instead. This has the side effect of making `mach
build-backend --diff` more readable for changes to that file.
Finally, make the backend.* files created like any other backend file,
such that its diff appears in the `mach build-backend --diff` output.
The FasterMake build system is meant to be invoked through `mach build
faster`, which does it already, or, in the near future, as part of an
hybrid build system, which will deal with it as well. People doing
`make -C objdir/faster` won't have the backend automatically refreshed,
but that's not a supported way to use it anyways.
While it would be possible to move those things in the export tier, it
is still interesting to have reporting for them separately, especially
considering I expect things to gradually move from the other tiers to
this new one.
While not entirely obvious, the recurse_pre-export target doesn't imply
actual recursion as long as the RecursiveMake backend doesn't emit
traversal information for it, so nothing will actually happen on this
target, but the interesting part is that it runs, per the generic
config/recurse.mk rules for tiers, between BUILDSTATUS TIER_START and
BUILDSTATUS TIER_FINISH, so that all its dependencies are accounted
as being part of the pre-export tier.
GENERATED_FILES impacts the export tier through the config/rules.mk
definitions, now moved to the backend itself, so that everything is
close to each other.
Turns out the claim in bug 1234439 that the FasterMake backend knows
about all the chrome manifest entries is wrong, and there's still one
that is added "manually" with buildlist.py, and during mach build
faster, that can happen before or after the corresponding chrome
manifests are written out by install manifest processing.
While the real fix here would be to make the build system totally
aware of those "manifest interfaces.manifest" entries, for now, it's
simpler to add dependencies to work around the race condition.
Collecting the list of object files compiled, while not ideal, will give us
some indication of how much work was involved in the build. This will help
with analyzing the data.

Limit ourselves to include paths for now, because there are tricky things
involved in making this globally.
While here, use shell_quote instead of manual quoting for those paths.
This might seem like going in the opposite direction of what we tend to do
to move to moz.build land, but those flags are irrelevant in many situations
and are better separated out.
MOZ_DEBUG_DEFINES are essentially defines used everywhere. So treat them as
feeding the initial value for DEFINES in each moz.build sandbox. This allows
the kind overrides that was done in the past by resetting MOZ_DEBUG_DEFINES
in Makefiles.
The only affected symbols are
_PR_<architecture>_Atomic{Decrement,Set,Add,Increment}, they are not exposed in
public headers, have a different name on each architecture, and have a public
API: PR_Atomic{Decrement,Set,Add,Increment}.
Currently, one needs to define DEFFILE or LD_VERSION_SCRIPT appropriately,
and somehow deal with the fact that their input format is different, which
currently relies on manual invocations of the convert_def_file script, with
awkward aggregations.
This simplifies the problem by using a simple list of symbols, with
preprocessing, allowing #includes.
Currently, only css files added through jar manifests are treated this way.
There is really no reason for the discrepancy, but there are actually no css
files added directly through moz.build, so this was never a problem.
On the other hand, it makes things simpler in a world where jar manifests are
treated as if they were entirely described in moz.build (which is where the
FasterMake backend is heading).
Using TEST_DIRS is nothing more than a shortcut for
if CONFIG['ENABLE_TESTS']:
DIRS += [...]
As such, we might as well remove it being a separate variable, and use some
Context magic to just fill DIRS when ENABLE_TESTS is set.
The security/manager/ssl/tests/unit/moz.build change ensures that the order
of DIRS before the change is kept, not because it matters, but because it
allows to confirm that nothing else is modified by this change.
Bug 1191230 added override lines with # characters to chrome manifests
for Windows.
So far, chrome manifests were handled with buildlist.py like in the
RecursiveMake backend, fed with Make variables. Without proper quoting,
those Make variables are just truncated by Make on the first # character,
and this results in mach build faster failing because of that.
However, the reason why chrome manifests were handled with buildlist.py
originally is that not all chrome manifest entries were known to the
FasterMake backend, but they now all are.
So instead of relying on Make variables and buildlist.py, we can now
rely on the newly added install manifests feature allowing to create files
with a given content.
We have many unit tests in the tree for some small parts of the build system
pipeline, but we don't have anything that resembles an end to end test, and we
kind of rely on the resulting Firefox not being broken by our changes.
With the Faster make backend growing, I want to ensure it produces the same
thing as the recursive make backend, at least for the parts it supports.
This adds some kind of test that allows to check that.
The test I'm about to add doesn't have XPIDL files, and that currently avoids
the FasterMake backend to run properly. Also, in the future, when the FasterMake
grows the ability to build C++ files, it should be possible to build Spidermonkey
with the FasterMake backend, but it doesn't have XPIDL files either.
This new ChromeManifestEntry object type is generic and can hold any kind of
chrome manifest entry, but we currently only emit them for binary components.
References to sub-directory manifests is left to the backend, for now, until
all manifest entries are emitted by the frontend.
This patch moves the logic for selecting MOZ_WINCONSOLE out of individual
Makefile.in files and into configure. It also changes config.mk to only
pass -SUBSYSTEM:CONSOLE if MOZ_WINCONSOLE=1. The MSDN docs state that
in the absence of -SUBSYSTEM, the linker will select the proper subsystem
based on whether the program contains [w]main or [w]WinMain, so let it
do that.
One program (windbgdlg) needed a tweak to add a wmain for when MOZ_WINCONSOLE
is defined.
This patch leaves one instance in security/sandbox/win/wow_helper/Makefile.in,
that Makefile has its own separate bug.

Dehydra/Treehydra is unmaintained, broken (iirc), and obsoleted by clang
static analysis. We've removed parts of the build system support for it, but
not all. This is meant to remove the remains.
