This seems like an easy first bug.

The intention of this bug is to get informative messages into the tbpl logs and determine if on mozdevice we should changes some messages to the right level.

The steps to follow would be:
* change the default mozlog.ERROR to mozlog.INFO [1]
* review the logging messages and see if they need to be change between info/debug/error
** change directory to testing/mozbase/mozdevice/mozdevice
** run "grep -E "(info|debug|error)\(" devicemanager*py" to find all instances
* attach your patch and request me to have a look
** once we have a good patch we can test it on try
* we can push to try with try: -b o -p linux64,android,emulator -u xpcshell,mochitest-1,crashtest-1,reftest-1,marionette-webapi -t none
** that would generate a series of jobs that would put your changes to the test
** you would have to have a

This is not too difficult, but is probably a bit involved for a good first bug. Let's make it a good next bug.

Thanks abhi12ravi for the patch. Overall the patch is heading on the right direction, however, somethings have changed since the bug got filed. I need to figure those out.

Hi wlach,
Since I filed the bug it seems that few things have changed.
At this point, we don't have a default logLevel as we used to [1].
From looking at tbpl, I can't see any output of mozdevice anymore.
I know that jgraham was excited to be able to see so much more output of mozdevice since it allowed him to know what was going on.

I think we have to discuss what we did on bug 1041533 and see if we have to change anything.
Otherwise we would have to go around the tree and have to set a level for each call of DeviceManagerADB.

What do you think?

On the other hand, this is not blocking anything but rather trying to improve our logging status.

Hey Armen, sorry about not giving feedback on this earlier.

I don't want to revisit bug 1041533, as that approach caused some pretty weird behaviour that was hard to track down. Also, I think most of the existing logging in mozdevice.DeviceManagerADB is at about the right level, I don't think we should change debug->info in most of the cases of's patch, the only thing that stuck out as the right thing was maybe the reverse switch from info->debug in the chmod calls.

I think at this point it would be best to focus on making mozdevice work well with structured logging, it's not really clear to me that further adjustments on how we're doing old-style logging in tree would provide a good return on time invested at this point. I suspect James or Chris would be the best people to ask about that.

Hey Armen and William, 

Thanks for taking a look at my patch. Do I wait till you guys figure out what's supposed to be done? Learning about the log levels was interesting, thanks for that!
Hey Armen, I think I'd like to just apply the two changes I mentioned in comment 7 and then close out this bug. Is that ok with you?
