What does your mozconfig look like?

Probably like the one when you search for "cat .mozconfig" in https://tbpl.mozilla.org/php/getParsedLog.php?id=31983334&full=1&branch=mozilla-central since automation's broken too.

This looks similar to my issue in bug 950410 I am attaching my .mozconfig

Here is my .mozconfig . $topsrcdir/browser/config/mozconfig BUILD_OFFICIAL=1 export BUILD_OFFICIAL WIN32_REDIST_DIR=~/mozilla/redist/x86 export WIN32_REDIST_DIR #WIN32_CRT_SRC_DIR=~/mozilla/crtsrc mk_add_options BUILD_OFFICIAL=1 mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/fx-obj mk_add_options RUN_AUTOCONF_LOCALLY=1 mk_add_options AUTOCONF=/usr/local/bin/autoconf-2.13 ac_add_options --enable-optimize=-O2 ac_add_options --disable-debug ac_add_options --disable-tests ac_add_options --disable-crashreporter ac_add_options --enable-metro ac_add_options --enable-jemalloc ac_add_options --without-x mk_add_options MOZ_MAKE_FLAGS="-j3"

Changing Importance to blocker since my blocker bug was duped here.

I am also removing xulrunner form the summary since Firefox builds fail as well.

Also, as I mentioned in bug 950410, not only does the build fail, but the build system seems to fail in an odd manner that it does not fail and exit, but continually loops on the error.

Also, as mentioned in bug 950410, this is building using MSVC 2010 express.

This is also likely not to be Windows specific.

This appears to be Windows only disable-tests only. At least my Android and Linux builds do NOT have this issue. Since I have verified that enabling tests results in successful builds, I am reverting my importance upgrade.

Not only on windows. I do not get a crash, but I got an error log on my archlinux too : 44:06.67 xpcshell 44:06.67 plugin-container 44:22.29 Traceback (most recent call last): 44:22.29 File "/usr/lib64/python2.7/runpy.py", line 162, in _run_module_as_main 44:22.30 "__main__", fname, loader, pkg_name) 44:22.30 File "/usr/lib64/python2.7/runpy.py", line 72, in _run_code 44:22.30 exec code in run_globals 44:22.30 File "/home/fred/logs/fox/src/python/mozbuild/mozbuild/action/webidl.py", line 17, in <module> 44:22.30 sys.exit(main(sys.argv[1:])) 44:22.30 File "/home/fred/logs/fox/src/python/mozbuild/mozbuild/action/webidl.py", line 13, in main 44:22.30 manager.generate_build_files() 44:22.30 File "/home/fred/logs/fox/src/dom/bindings/mozwebidlcodegen/__init__.py", line 287, in generate_build_files 44:22.30 written = self.generate_example_files(interface) 44:22.30 File "/home/fred/logs/fox/src/dom/bindings/mozwebidlcodegen/__init__.py", line 308, in generate_example_files 44:22.30 root = CGExampleRoot(self.config, interface) 44:22.30 File "/home/fred/logs/fox/src/dom/bindings/Codegen.py", line 10314, in __init__ 44:22.30 descriptor = config.getDescriptor(interfaceName, False) 44:22.30 File "/home/fred/logs/fox/src/dom/bindings/Configuration.py", line 176, in getDescriptor 44:22.30 for d in self.descriptorsByName[interfaceName]: 44:22.30 KeyError: u'TestExampleProxyInterface' Anyway I get a working Mozilla Firefox after this.

And I wonder if bug 950332 is more or less like this one.

OK you are correct. It seems the bug exists in all architectures, just under Windows the build loops on the error and never completes.

I'm able to reproduce on Linux. Interestingly, make also reported the build as successful - eventually. For whatever reason, I don't think the uncaught exception is being turned into a non-0 exit code. The plot thickens.

Previously, the set of WebIDL example interfaces to build was hardcoded in the mozwebidlcodegen Python package. Unfortunately, the example interfaces in that set were dependent on test-only bindings files, resulting in build failures when tests were disabled (because those test-only bindings were defined in a test directory). In this patch, we now declare example interfaces in moz.build files so the set of example interfaces lives next to the set of defined bindings files. The example interfaces are defined in a test moz.build file - in the same file declaring the bindings files that contain the interfaces - so the example interfaces only get picked up if the corresponding bindings are defined. We could probably switch WebIDL moz.build variables to use lists with flags. That would be good followup fodder. For now, let's fix the build. https://tbpl.mozilla.org/?tree=Try&rev=840f122d1286

Comment on attachment 8347769 [details] [diff] [review] webidl.patch Patch is busted. I thought it worked locally...

Fixed a typo in emitter.py. https://tbpl.mozilla.org/?tree=Try&rev=a3bd2f3eaa15
