Bug ID: 435908
Summary: valgrind tries to fetch from deubginfod for files
which already have debug information
Product: valgrind
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: jsew...@acm.org
Reporter: t...@compton.nu
Target Milestone: ---
The new debuginfod support in valgrind is rather over eager and will try and
fetch a debug image for files which already have debug information.
Development builds of the code I work on have about 250 shared libraries which
are build with full debugging but are not stripped at all so the debug
information is in the main image.
Because valgrind has always tried to find a debug image before doing any debug
lookups, and because that code not includes trying to search debuginfod for an
image, programs now takes several minutes to start while valgrind runs 250
debuginfod-find's each of which makes an HTTP call which gets a negative
result.
There is currently no negative caching in libdebuginfo (though it is planned)
so this isn't even a one time thing.
