Per discussions on Linux ,our Linux compatibility promise is "back to CentOS 6", and the best way to guarantee that is to build on that platform.

This will track the "latest" 6.x repos upstream, eventually with some kind of automatic bumping. RHEL's support timeline is https://access.redhat.com/support/policy/updates/errata#Life_Cycle_Dates which lists RHEL6 support extending through November 30, 2020 (although just for critical patches). Likely after that time, public mirrors of CentOS 6 will start to be taken down, and we'll be unable to generate updated docker images. But that's five years off! Ideally we can avoid referring to "custom" repositories (mockbuild-repos) at all and just use upstream packages, with anything else we require brought in from tooltool.
For my reference, https://reviewboard.mozilla.org/r/7805/diff/1#6 was my last attempt at setting up a centos6 docker image. We want to use mozbootstrap, though!
:glandium has just indicated that mozbootstrap for CentOS 6 is broken, and anyway tries to install a bunch of packages that should be installed from tooltool in automation, and fails to install other release requirements. But, I had gotten quite a way toward running mozbootstrap, including some docker backflips to solve bug 1188851. Here it is for my reference, in patch form. I'm going to start over, building a simple shell script to install a list of packages gleaned from the mock configurations in puppet and mozharness, but trimmed of the obvious cruft, such as a slew of extra copies of gcc.
Notes to self on progress - need to figure out how best to install a newer hg (emailed gps) - need to install python2.7 I'd like to avoid building a custom RPM repository, since then getting things uploaded to that repo is a hurdle to updating versions. I will try scripting out builds from source for these two items as part of the `docker build` process.
That worked; now 17:06:41 INFO - checking for gtk+-3.0 >= 3.4.0 gtk+-unix-print-3.0 glib-2.0 gobject-2.0 ... Package freetype2 was not found in the pkg-config search path.

Probably missing freetype-devel.

xrender.. I wonder if I have an old copy of the mock configs?

Attachment #8651160 - Flags: review?(mh+mozilla)
Thanks for the updates on what is and is not required - I'll update accordingly. If at all possible, I'd like to avoid hosting any custom yum repositories. Including a repository in the image-building process means that we have binary blobs of usually-unknown provenance involved, in an un-version-controlled environment (no history), with the risk that just adding a new package can cause existing processes to break. Such a repo also makes it difficult to self-serve updates to the docker images, as the updates require write access to the yum repo (with attendant risks). It's been kind of a nightmare so far! As for rebuilding the docker image to upgrade anything -- yes, I expect docker images to be rebuilt roughly weekly, and more frequently when needed. That achieves the goal of keeping images up-to-date with upstream updates, while allowing older jobs to be re-run in correspondingly old images. We will eventually have automation in place so that a change to testing/docker/<imgname>/VERSION triggers a build of the new version of <imgname> before executing tasks that will depend on that new image, so common tasks like upgrading mercurial will be a one-liner. As for downloading tarballs hosted outside Mozilla, there are three reasons not to do it, and one reason to do it: 1. Possibility that the remote tarball is corrupted, trojaning our image 2. Possibility that the remote tarball is unavailable, preventing building new images 3. Possibility that the file disappears forever, rendering us unable to rebuild the image vs. A. Allows self-serve changes to the docker image specification without access to some protected file storage (similar to the reasoning about yum repositories above) I'll also note that the docker images themselves are not hosted at Mozilla, so requiring that the sources for those images be hosted at Mozilla seems to be asking a lot. And finally, the upstream yum repositories we're using are not hosted locally (and for many of the reasons above, plus the nuisance of constantly re-mirroring, we don't want to mirror those locally). We can fix #1 easily enough by verifying a hash embedded in the source file. #2 isn't particularly problematic, as we can continue to build with the existing image. #3 may be an issue, although it's unlikely for the tarballs used so far. Probably the best fix is just to use tooltool to store and download these tarballs -- it satisfies 1, 2, 3, and A. So I'll take that approach. I can remove the packages required for the Python, git, etc. builds after those builds take place. I believe that the build process *does* perform git commits, although I don't know for sure. Defaults don't hurt.
A few other things to add: * Xvfb and xvinfo to support make test and PGO builds * a bit more cleanup -- `yum clean all` saves 240MB * installing Python stuff using peep, which gets the download verification we want
Hm, with Xvfb and xvinfo, I get a different 'make check' failure: https://tools.taskcluster.net/task-inspector/#bpAoT6V9QFS1vpKa9BXgEg/0 22:33:43 INFO - TEST-START | GeckoMediaPlugins.GMPTestCodec 22:33:43 INFO - [28858] WARNING: pipe error (31): Connection reset by peer: file /home/worker/workspace/build/src/ipc/chromium/src/chrome/common/ipc_channel_posix.cc, line 459 22:38:43 WARNING - gtest TEST-UNEXPECTED-FAIL | gtest | timed out after 1200 seconds This rings a bell -- I remember chasing down failures in GMP before.. ah, right, bug 1162965.
Sadly, peep is currently broken: https://github.com/erikrose/peep/pull/94 what a mess :(
Peep is working now. And the GMP tests pass on my system, which makes reproduction pretty difficult :( Also: 17:30:36 INFO - File "/home/worker/workspace/build/src/build/mach_bootstrap.py", line 356, in __call__ 17:30:36 INFO - module = self._original_import(name, globals, locals, fromlist, level) 17:30:36 INFO - ImportError: No module named _sqlite3 so the Python build needs some work.
FWIW, I don't think updated docker images every week is a practical approach from the perspective of making those images usable by local developers, especially for bisections that will spread across multiple weeks.
It's also probably not really nice for try, where people will usually push trees with various freshness, making build slaves need to clone various different images.
The docker images used are tied to the tree (they're named and specified in-tree) so bisection should be straightforward, and may determine that the image regeneration was at fault just as it might determine that a particular cset was at fault. Cloning different images is unfortunate, but ultimately not that problematic (the images are cached). So basically, I don't see an issue here, and the alternative (never updating build images) is not a mistake I am interested in repeating. I'm still working on chasing down the GeckoMediaPlugins error. So far, we have realpath(3) failing with EACCES on a fully qualified path to plugin-container within the objdir.

So far, we > have realpath(3) failing with EACCES on a fully qualified path to > plugin-container within the objdir. …because, ironically, it was running as root instead of the "worker" user. The plugin-container unshares the user namespace early in startup (see the call to SandboxEarlyInit in plugin-container.cpp), which implicitly drops all capabilities it may have had in the outer namespace. In this case, that means that when the process tries to realpath() itself, it accesses the filesystem as uid 0 without any of the usual "superuser" overrides. /home/worker is owned by "worker" and mode 0700; root is not the owner, so it has no permission to access anything inside there. It turns out that MOZ_DISABLE_GMP_SANDBOX doesn't disable that part of sandboxing, which made debugging unnecessarily confusing (and is not the intended behavior!); I've filed bug 1199413. And this doesn't happen if the kernel doesn't support user namespaces, which is why Dustin couldn't reproduce this locally (and why it *does* happen in a CentOS 6 container hosted on Ubuntu 14.04, even though actual CentOS 6 doesn't support any of our sandboxing).
Depends on: 1199379

Cloning different images is unfortunate, but ultimately > not that problematic (the images are cached). That's exactly the problem. Images are big. People will have to download dozens of gigabytes just to a bisect over a few weeks. And will have to download a new image every week, regardless of bisection. Well, that won't /have to/, they thankfully will still be able to build without the images, but docker images being advertised as something that's supposed to make their lives easier... > So basically, I don't see an issue here, and the alternative (never updating > build images) is not a mistake I am interested in repeating. Surely, there has to be a sweet spot between never updating and updating every day. Every week doesn't seem to be that.
This bug probably isn't the right place for this particular conversation.
It's not the right place for this discussion, but this discussion has an impact on this bug.
OK! A successful build with a CentOS 6 image https://tools.taskcluster.net/task-inspector/#QDmERbcFS52R67_6YmNgxA/0 The job didn't handle artifacts correctly, but that's another bug. I may hack around that temporarily in try just so I can get a working binary out to smoke-test on my laptop. Remaining clean-up: install yasm # probably need a newer/pinned version install valgrind # probably need a newer/pinned version install freetype-devel # probably need an older/pinned version for all three, I will put the relevant RPMs (from the repos used for mock) into tooltool and install them directly, avoiding all of the horrors of yum repositories.

There's bug 1198179 on part of that being broken, but I don't know what's up with the x-test stuff.
No longer depends on: 1199379
Great success with the RPMs in tooltool. I'll squash everything down and put it up for review again.

I dropped the ball on the image updates, sorry -- I'd like to get you and other build-team members more involved in the wider discussion, rather than just you and me. That decision is orthogonal to this patch, anyway. The single quotes avoid variable substitution in the heredoc body. Not necessary here, but good practice in general. I used the RPMs from tooltool, rather than a from-source build, because that's what was available. The build instructions for all of those aren't in the tree, so it's not clear how they were built. We have SRPMs for valgrind and freetype, so those are probably reproducible but to figure out how they were built requires some extra work And there's no SRPM for yasm, so I really have *no* idea how that was built. In general, I'd prefer an in-tree build script because it means that changes can be easily tested out in try and the provenance of the binary is clear. The separate tooltool invocations don't really make a difference -- tooltool downloads sequentially, anyway -- but it might read better with those rearranged (and with consistent JSON indentation!) I didn't do anything to *enable* ccache, so without digging I don't know how to disable it -- got a quick hint?
OK, that wasn't much digging: export CCACHE_DISABLE=1
It remains to fix up linux32 and asan builds here, but I'm going to put that on hold until we can get linux64 to tier 2.
As I was embarking on the construction of a 32-bit centos 6 image, catlee pointed out that we no longer use the mock-mozilla-i386 mock environment, preferring to build in the 64-bit environment with multilib packages installed.
I rebuilt the centos6-build image to include those multilib packages, per https://dxr.mozilla.org/mozilla-central/source/testing/mozharness/configs/builds/releng_base_linux_32_builds.py#37 The good news is, the Linux64 builds continue to work, so using a single image is still a possibility. The bad news is, the Linux32 builds failed: 22:01:07 INFO - Calling ['python2.7', 'mach', '--log-no-times', 'build', '-v'] with output_timeout 2400 22:01:07 INFO - Error loading mozconfig: /home/worker/workspace/build/src/.mozconfig 22:01:07 INFO - Evaluation of your mozconfig exited with an error.

Is that build using the same gtk3 package as the 64-bit build?
It shouldn't be -- it's using the 32-bit mozharness script, which points to /home/worker/workspace/build/src/browser/config/tooltool-manifests/linux32/releng.manifest
You're likely missing a few 32-bits libraries, specifically, from the log, at least libXtf, libpng and libfontconfig.

This often means that the root cause is something else and multilib version checking is just pointing out that there is a problem. Eg.: 1. You have an upgrade for freetype which is missing some dependency that another package requires. Yum is trying to solve this by installing an older version of freetype of the different architecture. If you exclude the bad architecture yum will tell you what the root cause is (which package requires what). You can try redoing the upgrade with --exclude freetype.otherarch ... this should give you an error message showing the root cause of the problem. 2. You have multiple architectures of freetype installed, but yum can only see an upgrade for one of those arcitectures. If you don't want/need both architectures anymore then you can remove the one with the missing update and everything will work. 3. You have duplicate versions of freetype installed already. You can use "yum check" to get yum show these errors. ...you can also use --setopt=protected_multilib=false to remove this checking, however this is almost never the correct thing to do as something else is very likely to go wrong (often causing much more problems). Protected multilib versions: freetype-2.4.12-6.el6.1.x86_64 != freetype-2.3.11-15.el6_6.1.i686
So we need to be using 2.3.11 on both architectures, not 2.4.12. Oops!
And CentOS 6.7 ships with 2.3.11-15, which is probably close enough to 2.3.11-6 for our purposes. Mike, can you confirm?

Putting that many multilib packages on the system seems to make "normal" compliation a lot harder. I managed to make Git and Python build by installing glibc-devel.x86_64. NPM builds were failing due to the lack of libstdc++-devel.x86_64. With that in place, I pushed to try: https://treeherder.mozilla.org/#/jobs?repo=try&revision=de0aa47e9fcd&exclusion_profile=false
Any version of 2.3 should work.

That failed with a missing Xrender on the Linux64 build, but success for Linux32. [root@taskcluster-worker ~]# rpm -qa | grep Xrender libXrender-devel-0.9.8-2.1.el6.i686 libXrender-0.9.8-2.1.el6.x86_64 libXrender-0.9.8-2.1.el6.i686 so we need to install that explicitly.

Looks like mozreview didn't recognize this as a distinct patch, and didn't give any in-bug indication that it required further review :( This is leaving a tier-2 job (android) orange, and blocking ehsan's work on bug 1208029, so I'm redirecting r? to ted in hopes we can land this before the weekend.

Sadly, no: No package zlib.{i686,x86_64} available. The gcc bit was a merge error of some sort -- thanks for spotting that! And no, the use of quay.io was only for testing.
I made some errors in the last push, around task configuration. My bad, but this stuff is rather non-obvious! This: - adds the 'linux' platform to `testing/taskcluster/tasks/branches/base_jobs.yml` so that it exists for all branches - removes the redundant `linux64` and `macosx64` entries in `testing/taskcluster/tasks/branches/try/job_flags.yml` (these might have been a merge error??) - refers to `linux` rather than `linux32` in `testing/taskcluster/tasks/branches/base_job_flags.yml`, causing it to run for all branches. Sorry for the extra review. On the plus side, green builds from the new image!
