Bug ID: 418219
Summary: Parsing entire project eats tons of memory
Product: kdevelop
Version: git master
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Language Support: CPP (Clang-based)
Assignee: kdevelop-bugs-n...@kde.org
Reporter: m.cenc...@gmail.com
Target Milestone: ---
SUMMARY
During parsing of entire medium-sized projects (~8K source and header files)
KDevelop process increases its RSS memory usage from ~300MBs to ~10GBs.
STEPS TO REPRODUCE
1. Open not yet parsed project
3. Watch memory usage in "System Monitor"
OBSERVED RESULT
Memory usage constantly increases during background parsing of every TU. Memory
is freed only after ~1 minute after the background parsing of whole project is
finished.
EXPECTED RESULT
Memory used during background parsing of given TU should be released almost
immediately after parsing of given TU is done, not after parsing of whole
project is finished.
