1301645 - Intermittent-infra Bad CRC-32 for file 'reftest/tests/layout/reftests/fonts/MiaoUnicode-Regular.ttf'

Status: RESOLVED FIXED

(Release Engineering :: Applications: MozharnessCore, defect)

Description

[Carsten Book [:Tomcat]]

in https://treeherder.mozilla.org/#/jobs?repo=autoland&revision=fd597b8d1dd62e173a89ba7e85b0a78805fa8add several tests failed with Bad CRC-32 for file 'reftest/tests/layout/reftests/fonts/MiaoUnicode-Regular.ttf'

like https://treeherder.mozilla.org/logviewer.html#?job_id=3325155&repo=autoland

seems this is not related to that changes in the patch because went green on the next run, but also its too frequent so that might be worth to check

The issue seems very isolate,I did not found any similar failed jobs lately.The problem is caused by the zip file 'reftest/tests/layout/reftests/fonts/MiaoUnicode-Regular.ttf'.
Error appear in_update_crc when checking the CRC to see if we're at the end of the file and get this condition:
 if eof and self._running_crc != self._expected_crc:
            raise BadZipFile("Bad CRC-32 for file %r" % self.name)
the script can be found bellow:
https://svn.python.org/projects/python/tags/r32/Lib/zipfile.py

Maybe Ed Morely can give us some advices as he encountered similar BadZipFile exceptions on Bug 894365 and Bug 1016473?

Bug 1300812 should have fixed this.
