1635563 - Support kaios in 'mach xpcshell-test'

Status: RESOLVED FIXED

(Testing :: XPCShell Harness, enhancement, P2)

Description

[Geoff Brown [:gbrown]]

I have a proof of concept in progress, for running xpcshell tests from mach, against the kaios emulator.

Comment 1

[Geoff Brown [:gbrown]]

To run mach from <b2g>/gecko, I find I need something like:

export MOZCONFIG=<b2g>/gecko/mozconfig-b2g
export MOZ_OBJDIR=<b2g>/objdir-gecko
export GECKO_OBJDIR=<b2g>/objdir-gecko
export PLATFORM_VERSION=29

When 'mach xpcshell-test' sets up the test files, it seems to parse all known test manifests, including mochitest manifests. A couple of the test manifests in <b2g>/gecko/b2g have support file references to non-existent files. I found I had to remove those bad references.

It seems to take about 20 seconds to initialize mozdevice and another 7 minutes to push all the xpcshell files to the arm emulator: We really need to switch to a faster emulator as soon as possible.

A very preliminary proof-of-concept demonstrating how we may be able to run
xpcshell tests on KaiOS.
Most code is copied from remotexpcshelltests.py; we may want to consolidate in future.
Currently this executes xpcshell on the KaiOS emulator, but xpcshell crashes,
possibly while reading the main head.js.

Once mach has setup the device, you can 'adb shell' and try to run things manually in the emulator. I find:

cd /data/local/xpcb
export LD_LIBRARY_PATH=/data/local/xpcb
./xpcshell -g /data/local/xpcb -a /data/local/xpcb -r /data/local/xpc/c/httpd.manifest -m # works - gives working js> prompt
./xpcshell -g /data/local/xpcb -a /data/local/xpcb -r /data/local/xpc/c/httpd.manifest -m -f /data/local/xpc/head.js # crashes

I don't see any minidumps created. Logcat shows the crash, but there are no libxul symbols and no obvious error messages prior to the crash.

Support 'mach xpcshell-test' in a KaiOS environment. This is very much like running
xpcshell in an android/geckoview environment except:

• instead of using an APK for the gre, use the omnijar
