1245008 - Something is wrong with hg on try on windows

Status: RESOLVED FIXED

Description

[Mike Hommey [:glandium]]

I have 3 builds on Windows on try that took close to an hour(!) to fail during configure (voluntary failure, at that). Turns out they spent an awful lot of time doing mercurial stuff:

First chunk of 20 minutes spent clobbering because mozilla-central != try:

16 minutes spent on try.hg unbundling:

Presumably, all of the above is linked to that mozilla-central != try thing.

This looks like to be the last build before mine on y-2008-spot-144:
http://archive.mozilla.org/pub/firefox/try-builds/[e-mail]-57d7278a3691efbc3eaf8c589628d28dba257d93/try-win32-debug/try-win32-debug-bm78-try1-build2437.txt.gz

and it says:

17:24:42     INFO -  command: START
17:24:42     INFO -  command: hg path default
17:24:42     INFO -  command: cwd: c:\builds\moz2_slave\try-w32-d-00000000000000000000\build\src
17:24:42     INFO -  command: env: {'HGPLAIN': '1'}
17:24:42     INFO -  command: END (0.25s elapsed)
17:24:42     INFO -  command: output:
17:24:42     INFO -  https://hg.mozilla.org/try
17:24:42     INFO -  command: START
17:24:42     INFO -  command: hg path default
17:24:42     INFO -  command: cwd: C:/builds/hg-shared\try
17:24:42     INFO -  command: env: {'HGPLAIN': '1'}
17:24:42     INFO -  command: END (0.25s elapsed)
17:24:42     INFO -  command: output:
17:24:42     INFO -  https://hg.mozilla.org/try

So presumably, at the end of that build, `hg path default` should still be https://hg.mozilla.org/try, but it's not when my build started:

21:42:33     INFO -  command: START
21:42:33     INFO -  command: hg path default
21:42:33     INFO -  command: cwd: C:/builds/hg-shared\try
21:42:33     INFO -  command: env: {'HGPLAIN': '1'}
21:42:34     INFO -  command: END (0.25s elapsed)
21:42:34     INFO -  command: output:
21:42:34     INFO -  https://hg.mozilla.org/mozilla-central

Created attachment 8715299 [details] [review]
https://github.com/mozilla/build-cloud-tools/pull/173

This PR to cloud tools updates the hg cache creation mechanism to correct the default path (in hgrc) for the try repository.

This is now patched in userdata (https://github.com/mozilla/build-cloud-tools/commit/e606df73088abcd7de3cd8b187fbdad08de5c8e9). Change should be quick to propagate as it's checked/applied on each reboot.
Please reopen, if issue persists.

Should it still be trying to unbundle try.hg? I have a couple win64 builds from 2 days ago that did that:

The log doesn't have the "path isn't correct" thing, so I guess that's a separate bug, actually related to bug 1247169.
