675036 - xpcshell unit_ipc tests hang on Android

Status: RESOLVED INVALID

(Core :: Networking, defect)

Description

[Geoff Brown [:gbrown]]

With patches for bug 668349 and 668351, the network xpcshell tests can be run on an Android device. Most of the /unit tests pass, but all of the /unit_ipc tests hang and must be skipped with "skip-if" entries in xpcshell.ini.

Breaking out of a /unit_ipc test provides log info such as:

That would be the problem.

Thanks so much Josh - I cannot believe I missed that! Unfortunately, after copying plugin-container to the device, these tests still crash, now complaining about libraries. These libraries are in the same location as xpcshell and plugin-container, and that directory is in LD_LIBRARY_PATH, so I'm not sure what the problem is.

[Geoff Brown [:gbrown]]

Found it! I needed to set the CACHE_PATH environment variable.

Comment 4

[Geoff Brown [:gbrown]]

After setting CACHE_PATH, all the unit_ipc tests pass. I have updated the patch on bug 668349 accordingly.
