1164636 - Make android GDB setup work with emulator builds

Status: RESOLVED DUPLICATE of bug 1219807

(Testing :: General, defect)

Description

[Bobby Holley (:bholley)]

Brad says that he will resource this once we get emulator mochitests hooked up to mach, which is bug 1164596.

I recently verified that gdb (JimDB) works fine with the Android emulator, and the coming-soon "mach emulator" command. https://wiki.mozilla.org/Mobile/Fennec/Android/GDB is helpful.

JimDB has support for running mochitests, and that too works fine with the emulator: work through the JimDB prompts and mochitests are launched on the emulator, with the debugger running.

I would like to see mach support for downloading and installing JimDB, similar to "mach emulator" - I can do that.

To make things even more simple and discoverable, it would be great if we could integrate JimDB with "mach mochitest", but I can't quite visualize that, yet.

Last I checked this wasn't the case, and I had to modify a bunch of the python scripts to get it to partially work. I guess that's been fixed?

Those both sound great. Also, when things are a mach command, the developer _knows_ it's supposed to a supported use-case, and is more confident filing bugs when it doesn't work.

:snorp has patches that let us run jimdb python scripts inside the gdb that's included in the NDK. That would make it a lot easier to run jimdb since the user should already have a copy of the NDK installed.

Let's see these patches.

Sounds interesting, but I'm not going to get into that. In bug 1219807, I deployed jimdb binaries to tooltool, for use from mach -- good enough for me.

This ended up being implemented in bug 1219807. mach can download, configure and run jimdb and jimdb can debug Firefox on a phone, tablet, or emulator.
