Document how to build the DLLs for the "modules" ping tests
In bug 1330833 some test DLLs were landed to allow testing for the following cases (see bug 1330833 comment 44 for more context): 1) PDB missing; 2) PDB containing unicode characters; 3) DLL name containing unicode characters. Instead of checking in the DLL binaries, along with the source code, we should generate them as part of the build process from the source. An example of this can be found at .  - https://dxr.mozilla.org/mozilla-central/source/build/win32/crashinjectdll/moz.build

I've generated one of them as part of the build process: https://hg.mozilla.org/integration/mozilla-inbound/diff/8fc28f2d52d9/toolkit/components/telemetry/tests/moz.build. Unfortunately it isn't possible for all of them, as the build system doesn't support Unicode well (and there are no plans to do it). It might be possible to generate the "PDB missing" one through the build system.
Ted, do you know if we are ok with (some) binaries in-tree in this case?
Note that we do already have other `.dll` and `.exe` files in-tree (more often `.exe` than `.dll`): https://dxr.mozilla.org/mozilla-central/search?q=file%3A.exe&redirect=false https://dxr.mozilla.org/mozilla-central/search?q=file%3A.dll&redirect=false
(In reply to Georg Fritzsche [:gfritzsche] from comment #2) > Ted, do you know if we are ok with (some) binaries in-tree in this case? I think as long as they're effectively just test data, and we have the source and a means to rebuild them if necessary checked-in alongside them it's fine.
Do we have documentation on how to rebuild the binaries for the dlls we can't generate through the build system? If not, would you kindly add it?
The source (if we can call it that :P) is the same as the libmodules-test lib (https://hg.mozilla.org/integration/mozilla-inbound/file/8fc28f2d52d9/toolkit/components/telemetry/tests/modules-test.cpp). Where should we add the documentation? In modules-test.cpp, in https://hg.mozilla.org/integration/mozilla-inbound/diff/8fc28f2d52d9/toolkit/components/telemetry/tests/moz.build, at https://hg.mozilla.org/integration/mozilla-inbound/file/8fc28f2d52d9/toolkit/components/telemetry/tests/unit/xpcshell.ini#l17, or in test_TelemetryModules.jsm? I propose in xpcshell.ini and in test_TelemetryModules.jsm.

Let's add a comment in test_TelemetryModules.jsm please!
For things like this, a comment in the test file pointing to the source file the library was built from, and then a comment (or comments) in the source file with the compiler commands to build the library should be fine. Rebuilding it ought to be an infrequent occurrence (possibly nobody will ever need to), but at least we'll know how to do so. :)
