Bug ID: 488379
Summary: --track-fds=yes generates errors that cannot be
suppressed
Classification: Developer tools
Product: valgrind
Version: 3.23.0
Platform: Other
OS: Other
Status: REPORTED
Severity: normal
Priority: NOR
Component: memcheck
Assignee: jsew...@acm.org
Reporter: arnaud.desit...@gmail.com
Target Milestone: ---
Using valgrind 3.23 built from source on Linux:
$ /usr/local/bin/valgrind --version
valgrind-3.23.0
# testing /usr/bin/true without --track-fds=yes
$ /usr/local/bin/valgrind --xml=yes --xml-file=xxx --gen-suppressions=all
--error-exitcode=111 /usr/bin/true && echo ok || echo fail
ok
# testing /usr/bin/true with --track-fds=yes
$ /usr/local/bin/valgrind --track-fds=yes --xml=yes --xml-file=xxx
--gen-suppressions=all --error-exitcode=111 /usr/bin/true && echo ok || echo
fail
==21042== (No origin, error cannot be suppressed)
==21042== (No origin, error cannot be suppressed)
==21042== (No origin, error cannot be suppressed)
==21042== (No origin, error cannot be suppressed)
==21042== (No origin, error cannot be suppressed)
==21042== (No origin, error cannot be suppressed)
==21042== (No origin, error cannot be suppressed)
==21042== (No origin, error cannot be suppressed)
==21042== (No origin, error cannot be suppressed)
==21042== (No origin, error cannot be suppressed)
fail
xxx contains most notably:
<error>
<unique>0x4</unique>
<tid>1</tid>
<threadname>true</threadname>
<kind>FdNotClosed</kind>
<fd>3</fd>
<path>.../xxx</path>
<what>Open file descriptor 3: ../xxx</what>
</error>
This relates to the file opened by valgrind itself.
So using "--track-fds=yes --xml=yes --xml-file=xxx --error-exitcode=111"
results in a non zero error code returned.
There is no way I can see to suppress the error using a suppression file.
"--gen-suppressions=all" results in "==xxxx== (No origin, error cannot be
suppressed)"
The new feature added in valgrind 3.23 by
https://bugs.kde.org/show_bug.cgi?id=328563 does not work properly when using
"--xml=yes --xml-file=filename" and "--error-exitcode=non-zero-error-code".
