1372993 - Assertion failure: chunkCheck == chunk, at …/netwerk/cache2/CacheFile.cpp:1736

Status: RESOLVED FIXED

(Core :: Networking: Cache, defect)

Description

[Nicolas B. Pierron [:nbp]]

STR:
 - about:config:
   * dom.script_loader.bytecode_cache.enabled = true
   * dom.script_loader.bytecode_cache.strategy = -1
 - visit: https://fossbytes.com/linux-open-source-weekly-news-roundup-fossbytes-8-october/
 - Crash with one of the following assertions:
   - Assertion failure: chunkCheck == chunk, at …/netwerk/cache2/CacheFile.cpp:1736
   - Assertion failure: !mListener, at …/netwerk/cache2/CacheFileChunk.cpp:568

These assertions happen after closing all alternate output stream.

Unfortunately, I was not able to reproduce it a fourth time for recording the log, and rr has a divergent execution.

Correction, I found the log file for the !mListener assertion:
https://drive.google.com/file/d/0B0XdfV25b2n5SHVqWTE2SXJMVTA/view?usp=sharing

Which is ending as follow:

[Main Thread]: D/cache2 CacheEntry::OpenAlternativeOutputStream [this=0x45a17c0, type=javascript/moz-bytecode-20170614155852]
[Main Thread]: D/cache2 CacheFile::Truncate() [this=0x532a960, offset=4853]
[Main Thread]: D/cache2 CacheFile::Truncate() - New last chunk 0x42b9180 got from mChunks.

I reproduce the first assertion by clearing the cache, and reloading quickly ~10 tabs including mastodon / twitter / github websites quickly, and crashed in less than 1 minute.

This one was fixed in bug 1378083.
