Hi,
I would like to set environment variable for try-comm-central job
submission to test C-C TB using MOZ_LOG as necessary.
The idea is to obtain log from MOZ_LOG for failing tests of
try-comm-central on architectures that I don't test locally (Windows
and MacOSX).
I test locally under linux.
HOWEVER, so far I have found there does not seem to be an easy method to
enable environment variable setting for C-C TB try-comm-central job
submission if I am not mistaken.
M-C FF submission has it easy, though.
Fact 1: For M-C Firefox build/test submission, it seems the following
method works.
./mach try fuzzy --env MOZ_LOG=cubeb:4 [1]
However, this has never worked for C-C TB build/test submission as far
as I could tell.
Fact 2-a: Thunderbird document states the following command should be
used for try-comm-central submission.
hg push-to-try -s ssh://hg.mozilla.org/try-comm-central -m "try: -b
o -p all -u mochitest --artifact"
Unfortunately, this does not seem to accept --env option.
I have been using the following simpler form of the above method to
submit try-comm-central job since the method available for M-C firefox
build/test did not seem to work
for C-C thunderbird try submission. I experimented this several years ago.
hg push -f ssh://hg.mozilla.org/try-comm-central
(I have forgotten why I did not use |push-to-try|. Possibly it was
because it may not work (?) with hg MQ extension nicely.)
Fact 2-b: I reconfirmed |mach try --env FOOBAR=1| does not work for C-C TB.
I just experimented the day before to see if the situation has improved
and the method for m-c firefox works for TB. It has not.
I tried to run the command, but it tries to submit M-C job submission
instead. Not quite what I intended. |mach try| seems to be intended only
for M-C firefox try submission.
So it does NOT work for C-C TB at all.
In "comm" subdirectory:
../do-make-tb.sh try --env FOOBAR=1
This submitted the m-c firefox submission. :-(
(do-make-tb.sh is a shell script wrapper that sets various environment
variables for my local compilation and then invokes
|mach| which is under "mozilla" directory, a parent directory of "comm".)
So it seems as if there is no easy way to set environment variable(s)
for C-C TB try build/job submission.
Fact 3: Then I found the following description in [3]
Re-running tasks with custom parameters from Treeherder
...
Some of the parameters that you can change are (see screenshot above):
---> Environment variables (e.g. MOZ_LOG) <---- !!!!
Modify Python's logging level
Path of the test to execute
Gecko preferences (think of about:config)
Run a test repeatedly
Run until the test fails
It sounds nice, but given that |./mach try fuzzy --env MOZ_LOG=cubeb:4|
won't work for C-C TB, I have grave doubt if this works for C-C
try-comm-central job.
Q1: Does this feature to set environment variable work from the
treeherder menu work for C-C TB try-comm-central submission?
Q2: If it works, does one need an additional credential to invoke this
feature? Say, I can submit a try job today, but would I need an
additional credential to invoke such actions? I think I need additional
credential.
Please note that many features available for m-c firefox job submission
are missing for TB and I am afraid this is one of such features.
Thank you in advance for any guidance on this matter.
