Viewer Crash Reporting
This article is obsolete, but kept as a historical record. Do not rely on this information in any way. However, it may be used in the future, so please do not delete or modify.
- Report all crashes properly (opt-out available)
- Make crash report processing automatic and immediate
- Make crash report data useful
Studio Shiny has committed to making the Second Life viewer more stable. This involves finding and fixing viewer crashes. We have found that the existing crash reporter doesn't help us as much as it should. It doesn't always give us the data we need to investigate crash patterns, doesn't scale to SL's current size, doesn't always report a crash, in fact, sometimes the crash reporter itself crashes.
- Create central library of crash reporter functionality
- Get near 100% of all crashes reported with the call stack included, which pinpoints the function or method in which the crash occurred.
- Refinements to the crash reporter functionality
- properly capture crashes before login or viewer initialization
Viewer Crash Hunters
- Our team of engineers will utilize the new Viewer Crash Reporter to identify the highest reported crashes and investigate the call stacks to pinpoint bugs.
- The project is gated on the adoption of
- the 220.127.116.11 viewer - which utilizes the new crash reporter.
- the 1.19.1 viewer - which also provides stack info on "deadlocks" (in which a crash occurs, but in a different thread.)
- implementation of a thread watchdog process (in 1.20 RC7 viewer) to detect deadlock situation and force a "normal" crash that reports the crashing thread
- the 1.21 RC viewer - which provides even more detailed call stacks
- Crash Hunters will analyze crashes and make fixes directly into the Release Candidate (RC) branch
- NOTE: This is a more aggressive introduction of code into the RC branch cycle, which may in the short term increase the "beta nature" of the Release Candidate during its early iterations (RC1, RC2, RC3)
- the benefit will be a longer-term effect of reducing the crash rate dramatically for all Residents by the time that a Release Candidate becomes the final candidate (RC4, RC5).
- Most crashes currently manifest in problems of the rendering code, so many fixes (and then, possible new bugs!) will appear in rendering options.
