When I originally implemented bug 1458161, this is how it was done, but
it was suggested to use a configure-time check. This turned out to not
be great, because the rust compiler changes regularly, and we don't run
the configure tests when the version changes. When people upgraded their
rust compiler to 1.27, the code subsequently failed to build because the
features were still set for the previous version they had installed.

We're well overdue for an upgrade of the rust compiler requirements.
Now that we're building with 1.28 (albeit a beta, due to be bumped when
it's released), we can bump the requirement away from 1.24 which is now
old. 1.27 is too new, though, so settle for the older 1.26.

When we're running using pipenv, we have more than one virtual environment. This means the current check to see if python matches the initial virtual environment gives a false positive when we're in a secondary virtual environment. This patch changes the condition to check if the current python path exists within the virtual environments root directory.

- allow to specify a linker to use explicitly
- check that using the corresponding linker flags makes us use that
linker
- if no linker is specified, and developer options are enabled, we want
to try to use gold if it's available, otherwise, we want to detect

--enable-release not being passed means developer options are enabled,
which is generally speaking not desirable for builds meant to be
shipped. This is somewhat alleviated for Firefox by MOZILLA_OFFICIAL
implying --enable-release (as well as MOZ_AUTOMATION), but that doesn't
apply to e.g. standalone js builds (even some of the standalone js jobs
on our automation don't set MOZ_AUTOMATION for some reason).
A reasonable thing to do is just to default builds for release/beta
milestones to --enable-release, but still allow --disable-release
to enable the developer options.

This option does nothing if it's provided, and things will probably
break in some most peculiar manner if somebody uses --without-pthreads.
Given that neither outcome is useful, we should remove the option.
OOM rust crashes are currently not identified as such in crash reports
because rust libstd handles the OOMs and panics itself.
There are unstable ways to hook into this, which unfortunately are under
active changes in rust 1.27, but we're currently on 1.24 and 1.27 is not
released yet. The APIs didn't change between 1.24 and 1.26, so it's
fine-ish to use them as long as we limit their use to those versions.
As long as the Firefox versions we ship (as opposed to downstream) use
the "right" version of rust, we're good to go.
The APIs are in their phase of stabilization, so there shouldn't be too
many variants of the code to support.

We previously did not require Python 3.5+ everywhere because we failed
to detect Python 3.5 on Windows in CI. That's because CI isn't using
start-shell.bat and it hasn't yet updated PATH to include
%MOZILLABUILD%\python3.
We shouldn't need to teach CI to have PATH contain everything in
MozillaBuild. This commit teaches moz.configure to automatically use
MozillaBuild's Python 3 if we're running in MozillaBuild.
Since we can now detect Python 3 everywhere in CI, we make Python 3.5+
required on all build configurations.

We want this on for "normal" developer builds, but we want to leave it
off when the build is for some kind of profiling, i.e. when the
optimization level is higher than "normal" builds.
This will tell us which functions PGO is spending its time in,
which functions are being optimized, and other interesting

This is a new issue that gets linted with flake8 3.5.0. Basically you should
never use a blank except: statement.
This will catch all exceptions, including KeyboardInterrupt and SystemExit
(which is likely not intended). If a catch all is needed, use
`except: Exception`. If you *really* mean to also catch KeyboardInterrupt et
al, use `except: BaseException`.
Of course, being specific is often better than a catch all.

We currently turn off the C++14 sized-deallocation facility on MSVC, and
we'd like to ensure we do the same thing for clang and gcc. To do so,
we add new functionality to moz.configure for checking and adding
compilation flags, similar to the facility for checking and adding
warning flags. The newly added facility is then used to add
-fno-sized-deallocation to the compilation flags, when the option is
supported.
Once we do this, we can't define the sized deallocation functions in
mozalloc.h; the compiler will complain that we are using
-fno-sized-deallocation, yet defining these special functions that we'll
never use. These functions were added for MinGW, where we needed to
compile with C++14 ahead of other platforms to be compatible with MSVC
headers. But they're no longer necessary, though they would be if we
removed -fno-sized-deallocation; the compiler will complain if we do
that and we'll add them back at that point.
We have code to test whether particular flags are supported for the
compiler we're using. Unfortunately, that code is tied up with checking
for warning flags. We're about to add a separate facility for generic
compilation flags, and we'd like to avoid cutting and pasting code if
possible. Let's split the core code out into a separate, reusable function.
Our toolchain detection logic checks whether we can reuse the target
C (resp. C++) compiler for the host compiler. This is generally only
applicable in the not-cross-compiling case, but we had special logic to
check for clang in the cross-compiling case and accept it, as clang is
able to generate code for multiple architectures from a single compiler
binary.
Our recent switch to clang on Android has exposed a problem in this
logic: we would never check whether the target clang, compiling for the
host, could actually find the host's headers. This was especially
problematic on OS X hosts, where the host clang contains special logic
to grovel inside the XCode installation to find C++ headers. The clang
from the NDK, however, was ignorant of the XCode installation.
Therefore, the NDK clang would happily compile code for the host, even
including C headers for the host, but would be hopelessly lost when it
came to compiling C++ headers during the actual build.
In hopes of mitigating this, we now include a check for a representative
header for C and C++ when checking compilers for each of those
languages. This check will detect such problems as the above, and will
also alert people to potentially misconfigured compilers in other
situations.
We need to modify our test framework to cope with headers being
included, since our mock environment isn't actually equipped with a full
set of compilers and headers.
Now that extra_toolchain_flags includes stlport_cppflags, there's no
reason bindgen_cflags_defaults should depend on them both. So remove
the stlport_cppflags dependency. (There's no harm to multiply-including
stlport_cppflags, but not repeating -I options is good practice.)
extra_toolchain_flags is used for compiling target-specific bits of code
elsewhere in configure. Very shortly, we'll need to compile bits of
code that depend on the C++ standard library, so we'll want to point the
compiler at the C++ standard library. Making extra_toolchain_flags
include stlport_cppflags is the best way to do that.
extra_toolchain_flags is going to depend on stlport_cppflags
momentarily, so this commit is just for moving code around. Note that
the diff shows other things moving *after* stlport_cppflags.
We compute the same set of data in extra_toolchain_flags as we were
computing in bindgen_cflags_defaults. We might as well reuse the former
to compute the latter.
The current code will fail if "RUSTC_OPT_LEVEL=" is passed. This can happen
if the value isn't present and that fact is injected into js' configure. We
only want to respect RUSTC_OPT_LEVEL if a value is passed, so we simply check
for the presence of a value rather than its origin.

The changesets in bug 1412932 changed the semantics for MOZ_PGO.
Before, it was effectively being set as an environment variable
by client.mk all the time. Afterwards - specifically after
2013c8dd1824 - the variable is set in mozconfigs via ac_add_options,
which means it is only exposed to configure, not the environment.
Investigation by dmajor revealed that -WX (warnings as errors) was
added to a js/src file's compiler invocation after the PGO code
refactor. (PGO and warnings as errors have a strange interaction
- bug 437002 - and should be disabled there.) Strangely, addition
of -WX was only present on Dev Edition PGO builds.
The reason for this is likely mozharness. Mozharness will export
the MOZ_PGO=1 environment variable for build configurations that
it knows are PGO. It appears to do this for all PGO build
configurations except Dev Edition. Since make and moz.configure
inherit environment variables, mozharness was basically papering
over the intended behavior change in 2013c8dd1824.
This commit fixes the problem by marking MOZ_PGO as a JS option
in moz.configure. This means `ac_add_options MOZ_PGO=1` (the new
convention for enabling PGO) will set MOZ_PGO for SpiderMonkey's
moz.configure.
Of course, MOZ_PGO=1 in an environment variable still works. And
mozharness's setting of this variable has the intended effect.
Eventually, I'd like to clean up the mozharness code so it is less
PGO aware and enables PGO via ac_add_options. But that's for another
day.

This was mainly used to support Universal MacOS builds, which were
removed several months ago.
In theory, someone could be using this feature to build multiple
applications with one build system invocation. But given that client.mk
is no longer the preferred interface to the build system and multiple
applications can be built by running `mach build` with different
mozconfigs, I don't think support for this feature is worth keeping.
This commit removes support for MOZ_BUILD_PROJECTS and related

MOZ_CURRENT_PROJECT in configure and mozconfig evaluation has also

LineIO currently attempts to convert bytes to unicode using the
system preferred encoding. This can obviously fail for some byte
sequences.
In many cases, the conversion is happening for purposes of logging.
In these cases, Unicode validation shouldn't be that important to
us.
So, this commit teaches LineIO to accept an argument defining its
Unicode error mode. We also teach relevant users of LineIO doing
logging to switch the default mode from "strict" to "replace" so
invalid Unicode byte sequences can be logged with the Unicode
replacement character.
During review, glandium pointed out that it may make better sense
to defer Unicode decoding to the logging layer instead of in LineIO.
I agree with this idea. But it can be implemented in another bug:
for now we should unbust the build system.

The NDK clang needs to be informed about the existence of a GCC
toolchain, so important programs like the linker can be located. With
this change, we're starting to use command-line options that are
incompatible with GCC, so we also add a check to inform the user about
the non-support for this configuration.
Our normal method of locating the compilers in the NDK is to set
--with-toolchain-prefix when compiling for Android. However, the clang
binaries are in a different location than would otherwise be implied by
--with-toolchain-prefix. Additionally, we still need to know about
--with-toolchain-prefix because the NDK clang needs to be pointed there
so clang can find important binaries like the linker and because various
other bits of the build system depend on the --with-toolchain-prefix
value as well.
So we need a separate mechanism for communicating the whereabouts of the
NDK clang. We can't set CC and CXX because doing so would conflict with
the CC and CXX values exported to the js/src/ subconfigure. But Android
already has an extra_toolchain_flags function that we use for informing
moz.configure about additional flags needed solely for Android, and we
can use a similar trick to communicate the existence of the NDK's clang
to the main C/C++ compiler selection process.
We subtly changed from "-C opt=value" to "-Copt=value" in 472232499478
(bug 1411081). This change appears to confuse sccache (which has its
own option parser).
This commit restores the old behavior of using separate arguments
for -C and its value.

While we're here, provide a reference to unique_list as defined in

As the data in the bug shows, the current default of opt-level=2 is
several minutes slower at compiling than opt-level=1. This slows down
builds significantly and the added benefits of running opt-level=2
for local development can't be justified for the common/default case.
This commit changes the default for local builds from opt-level=2 to
opt-level=1.
--enable-release (what we use for builds shipped to users) will imply
opt-level=2. --enable-optimize (the default) will use opt-level=1,
and --disable-optimize will use opt-level=0.
The RUSTC_OPT_LEVEL environment variable in mozconfigs can be used
to set an explicit opt-level level, regardless of what other
configure options are set. This includes the other potential values,
"s" and "z."
A side-effect of this change is that -Copt-level is now *always*
specified by the build system. Before, it was only specified if
the value was adjusted to 0 for --disable-optimize builds.

Before this commit, RUSTFLAGS was derived in rules.mk by consulting
various variables set by configure. It isn't clear to me why things
are implemented this way. We don't appear to have moz.build level
overrides for Rust compiler flags. So there doesn't appear to be a
compelling reason why we can't derive these values in configure.
So, this commit ports the code for deriving default RUSTFLAGS from
rules.mk to toolchain.configure.
The port is pretty straightforward as far as the logic goes.

The Rust optimization logic is tied to --enable-optimize/MOZ_OPTIMIZE
and --enable-debug/MOZ_DEBUG. In order to more easily implement more
customization, let's move --enable-optimize/MOZ_OPTIMIZE to
moz.configure so its value can be consulted there.
The logic here is a bit wonky. The option behaves like a boolean
or a string. If a string, MOZ_OPTIMIZE is set to 2. Otherwise it
is 1 or unset depending on the boolean value.
The custom compiler flags string is passed to old-configure, where it
overwrites whatever old-configure derived as the default value.
We stop short of moving all references to MOZ_OPTIMIZE_FLAGS to
moz.configure because there are a handful of them and I don't want
to scope bloat.

Per schedule, bump the minimum-supported rust version to 1.21.0
two weeks after its stable release so we can use new code which
depends on it.

By the schedule we would have bumped the minimum-supported rust
version to 1.20.0 some weeks ago, just before Firefox 57 went to
beta. However, that was blocked on a couple of compatibility
issues with sccache and dsymutil. See bug 1396884.
Now that 1.20.0 is working in our automation builds, require
it for all builds to unblock servo and webrender upgrades.
Also update our integration test to verify building with
the new minimum.

Building Fennec/Android uses cross compiler toolchain. So we have to generate
clang options (include path for c++ headers and gcc headers, gcc-toolchain path and etc) from NDK path for bindgen.
The following options are required for android build.

Because Rust tests require panic=unwind crates and therefore recompiling
all crates we normally use (since most of our crates use panic=abort),
we've elected to enable Rust tests only if the user asks for it. Hence,
this configure option.
The configure option also enables build-time execution of the crates,
since it's not straightforward to determine at configure time the name
of the test binary Cargo will produce (Cargo produces test binaries of
the form ${NAME}-${HEX_FINGERPRINT}, but there's no way to determine
what ${HEX_FINGERPRINT} is without actually compiling the test binary).
There is a known compilation bug that is fixed in Visual Studio 2017
15.3.
This commit establishes minimum version requirements for Visual
Studio 2017 to ensure modern and more supported toolchains are used.
We previously only had a minimum version requirement for Visual
Studio 2015.

Technically this turns on gnu++14. I encountered a few errors when using c++14:
1) _USE_MATH_DEFINES needed to be defined for MinGW
2) MinGW did not define _finite under c++14
3) MinGW's float.h did not define Microsoft specific float functions under c++14
All of these were because c++14 defines _STRICT_ANSI_ which MinGW obeys and
avoids defining certain functions. The first two could be patched around, but
the third was a blocker, so we switched to gnu++14

toolchain.configure checks for information about the compilers we're
using and accumulates additional flags that we might need to
pass (e.g. switches for C/C++ versions, proper compiler targets, etc.),
and then rechecks the compilers with those additional flags to verify
that those flags are sufficient to configure the compiler properly.
Only after we've checked for the proper flags do we move on to verifying
the compiler versions are sufficient.
It's possible, however, that the flags we try to add might not be
supported by the compiler being tested, in which case we'd get an
unfriendly error about an "unknown compiler", rather than something like
"version X of Y not supported". In this case, we'd rather use the
information we gathered from the first run to provide information
messages. So we modify the second check to ignore any thrown exceptions
during the check itself.
This change results in another problem: the check for whether we had any
extraneous flags is done prior to version checks for the compilers we
support, which is also unhelpful. We choose to move this check after
the version checks themselves.
gcc 4.9 is the last version in Android NDK and our minimum requirement of gcc is 4.9+. --with-android-gnu-compiler-version is unnecessary option because gcc version of Android is always 4.9.

The linker detection essentitally invokes `$CC -Wl,--version` to
determine which linker will be used. This invocation works OK for GCC
from the Android NDK, which can find the linker in the same directory;
it doesn't work so well for clang from the NDK, which needs additional
command-line options to point at the directory containing the linker.
We already have extra_toolchain_flags for communicating such options to
other compiler invocations for the target; we should be using
extra_toolchain_flags here as well.
In some cases, they are false positives. In other cases, the callsite is #ifdef-ed
out, so it's a true positive, but not one we would correct.

The Repository interface gains a new method to determine if a sparse
checkout is present. Mercurial's implementation is somewhat crude,
but it should work (Mercurial's sparse support is still experimental
and I only intend to support sparse checkout in Firefox CI until it
is less experimental). Git's always returns False (for now).
To prove it works and to expose the information more widely, we hook
it up to moz.configure. We do this by first implementing a function
that returns a Repository instance. Then we simply call a function on
it to resolve the sparse checkout flag.

We define extra_toolchain_flags for passing extra flags to the target
compiler during configure. But the way things are currently set up, we
pass those flags to the host compiler during configure as well. This
behavior is incorrect, and we should only be passing the flags from
extra_toolchain_flags if we're compiling for the target.

Various people want to start experimenting with Python 3 in the build
system and in related tools (like mach).
We want to make it easy to find and use an appropriate Python 3
binary.
This commit introduces a generic function for finding a Python 3
binary and resolving its version.
We use the new code in configure to set PYTHON3 and PYTHON3_VERSION
subst entries for later consultation.
We also expose a cached attribute on the base class used by many
mach and build system types to return a Python 3 executable's info.
By default, we only find Python 3.5+. From my experience, Python 3.5
was the first Python 3 where it was reasonable to write code that
supports both Python 2 and 3 (mainly due to the restoration of the
% operator on bytes types). We could probably support Python 3.4
in the build system. But for now I'd like to see if we can get
away with 3.5+.

Bump the minimum required version of the Rust toolchain to
the current stable release so we can take advantage of new
features.
Highlights of the 1.19.0 release:
* C-compatible `union` (untagged enums).
* Support for Visual Studio 2017.
* Non-capturing closures can be coerced to `fn` bindings.
* Numeric field names in tuple struct initializers.
* Higher macro recursion limit.
* `break` can return a value from `loop` expressions.
* Better error handling with mis-configured Visual Studio environments.
This change also enables 1.18.0 features. Some highlights:
* `pub(mod)` &c. for better control of symbol visibility.
* struct packing for better memory footprint in generated code.
* Faster build times.
