; A log of what was happening around the time the problem happened: This can take the form of the GeckoDump logcat category or a log generated by the secret debug mechanism.
* logcat log of what the e-mail app was doing:
** First, you need to make Make sure that your build e-mail logging is running with the "browserenabled.dom.window.dump.enabled" preference It probably is set to true for your build. You will know this is the case if your If you are running logcat output shows "LOG: got localized!" and see "LOG: Mail universe/bridge created, notifying" when you start the e-mail app. It appears that nightly builds do have this setting on by default, but then it's very confusing.working! Congrats! Otherwise, to turn it on:
*** You can enable the preference in your own gaia builds by creating a file GAIA/build/custom-prefs.js (note: this used to be GAIA/custom-prefs.js, but it changed) and making sure it includes the line: pref("browser.dom.window.dump.enabled", true);
*** I hope there's a better way, but if not, if you just want to change the setting on the device, you will need to modify /data/b2g/mozilla/PROFILEDIR/prefs.js to include the line. See below for one way to do this.
** Second: make sure the logcat stays connected even when the screen locks / the display turns off. You have to have both "remote debugging" enabled (which is what makes logcat work at all), and you need to disable the lock screen in order for logcat to remain connected. There are other ways to make this happen, but they are technical and I don't know them. Feel free to include instructions here.** Please provide the logcat by running '''adb logcat -v time -s GeckoDump:V Gecko:V | tee FILENAME-TO-LOG-TO'''. Please start running this command BEFORE you attempt to reproduce the problem. logcat uses a circular buffer that discards older entries when the buffer fills up, so if you run logcat only after the problem happens, you may not have all of the logic. Once you are done, hit control-C and send us the file.
**** The logcat arguments filter out a lot of the noise that we don't care about and gives us timestamps.
**** The "tee" command lets you see the output while also logging the output directly to a file. This way you don't have to copy and paste the log.
