Status updates for the week of 2018/10/15

• I triaged October 6th's nightlies and filed bug 1497143 - Crash in java.lang.IllegalStateException: at android.support.v4.app.FragmentManagerImpl.saveAllState(FragmentManager.java), bug 1497145 - Crash in java.lang.OutOfMemoryError: at android.database.CursorWindow.nativeGetString(Native Method), bug 1497148 - Crash in java.lang.IllegalArgumentException: at org.mozilla.gecko.GeckoProfile.<init>(GeckoProfile.java), bug 1497149 with two distinct signatures - Crash in OOM | large | NS_ABORT_OOM | nsTArray_base<T>::EnsureCapacity<T> | mozilla::dom::HTMLMediaElement::DispatchAsyncEvent
• I updated and landed the fix for bug 1390547, now multi-line MozCrashReason annotations are properly handled both in Rust and C++
• I wrote a fix for bug 1497692 which lowers the priority of the minidump-analyzer tool after a crash. The goal is to let the user go back to what it was doing ASAP
• I prepared a patch for bug 1498609 which will tell us which of our users are using ECC memory and which are not. I also prepared a data review request since this is new data we didn't collect before
• I've spent some time gathering information on how to implement crash pings for GeckoView in bug 1483331. I've got a plan almost ready for that
• I've further worked on bug 1435683, integrating the new prototype service with the XPCOM machinery and finishing the script that generates the list of topics
