We wouldn’t get good stack traces if a crash occurred in one of these packages instead of Firefox itself because we didn’t have symbols for them either. To make matters worse, Firefox depends on a number of third-party packages (such as GTK, Mesa, FFmpeg, SQLite, etc.). The Firefox builds that submitted the reports weren’t done by us. This posed a significant problem when dealing with stability issues on Linux: for the majority of our crash reports, we couldn’t produce high-quality stack traces because we didn’t have the required symbol information.

When it comes to Linux things work differently than on other platforms: most of our users do not install our builds, they install the Firefox version that comes packaged for their favourite distribution. If Socorro doesn’t have access to the appropriate symbol files for a crash the resulting trace contains only addresses and isn’t very helpful: Here’s an example of a proper stack trace: Equipped with this information Socorro can produce a human-readable stack trace. In regular Firefox releases, we extract this information from the build files and store it into symbol files in Breakpad standard format. Symbol information contains the names of the functions corresponding to a given range of addresses as well as the source files they come from and the line numbers a given instruction corresponds to.

The unwinding information is a set of instructions that describe how to find the various frames in the stack given an instruction pointer. To extract a meaningful stack trace from a minidump two more things are needed: unwinding information and symbols. See the picture below for an example of how crashes are grouped: When a new crash is spotted we assign it a bug and start working on it. The reports are then clustered based on the top method name of the stack trace of the crashing thread. Once the user submits a crash report, we have a server-side component – called Socorro – that processes it and extracts a stack trace from the minidump.

Breakpad originated at Google for their software (Picasa, Google Earth, etc…) but we have forked, heavily modified for our purposes and recently partly rewrote it in Rust. The minidump format was originally designed at Microsoft and Windows has a native way of writing out minidumps. If you’re familiar with core dumps, then minidumps are essentially a smaller version of them. This includes the contents of the processor’s registers as well as data from the stacks of every thread. This report contains, among other things, a minidump: a small snapshot of the process memory at the time it crashed.
This effort quickly became an example of good synergies between FOSS projects.Įvery time Firefox crashes, the user can send us a crash report which we use to analyze the problem and hopefully fix it:

NuGet package restoring ready, and no need to commit any WebDriver binary files into source code control repository. These NuGet packages will download Selenium WebDrivers (Chrome, Firefox, Internet Explorer, and PhantomJS) into your Unit Test Project.Įach WebDriver binary file does not appear in Solution Explorer, but it is copied to bin folder from package folder when the build process.
