CLion freeze dump parser

Automatically detects issue IDs related to a CLion freeze.

Usage

./cidr_freeze_parser.py dump.txt > result.txt
./cidr_freeze_parser.py freezeFolder > result.txt

Results are printed to stdout. If -o flag is passed, results are saved to the out directory as well.

If a folder name has a threadDumps-freeze-20 substring, all containing dumps are assumed to have a single cause (and only one is processed).

Prerequisites

Python 2 or 3

Output

• prints a summary of the possibly found issues
• prints a file:issue mapping
• prints the EDT stack trace for unrecognized traces

TODO

• more issue IDs (patches are welcome)
• better error handling
• extract wait duration from the folder name
• zip archives processing
• handle cases where EDT is waiting (e.g. on a read/write lock); report non-waiting traces with it
• have a persistent DB of processed traces
• Refactor the code to use a single generator that pipes straight to the analyzer (so if a file from a theadDump folder fail to parse), we can take a next one instead.
