TIMEOUTFACTOR on glibc test suite

[Gilles Espinasse]

I find in fedora TIMEOUTFACTOR=16 to eliminate the possible timout errors. Seen same variable in debian build. With that, I am able to build glibc without any error on amd-xp 3000+ or amd xp2800+ Without TIMEOUTFACTOR, I had Timed out: killed the child process make[3]: * usr/src/glibc-build/stdio-common/bug22.out Error 1

For the TIMEOUTFACTOR value, I am stupid and blindy use the value like in Fedora. I am using -march=i486 -mtune=native -O3 -pipe -mno-tls-direct-seg-refs to be virtualisation friendly.

May I suggest to parse glibc error log in a way that skip (ignored) error with grep ' Error [0-9]\+$' glibc-check-log

[Julio Meca Hansen]

Nice finding, I never thought on that way to supress the timeout errors :)

But how do you specify the variable? Something like...

TIMEOUTFACTOR=16 make -k check 2>&1 | tee glibc-check-log

... ? Or how?

[Gilles Espinasse]

Sorry I forgot to write how to use it. Yes basically define TINEMOUTFACTOR in the test environment. I use

TIMEOUTFACTOR=16 make -k check

On a x86_64 system and glibc-2.11.2 I get:

grep Error glibc-check-log
make[2]: [/sources/glibc-build/posix/annexc.out] Error 1 (ignored)
make[2]: *** [/sources/glibc-build/nptl/tst-attr3.out] Error 1

make[1]: *** [debug/tests] Error 2
make[1]: *** [/sources/glibc-build/c++-types-check.out] Error 1
make: *** [check] Error 2

Without the TIMEOUTFACTOR, I get one less error: tst-cpuclock2.out does not fail.

Updated explanation of glibc timeout errors and added TIMEOUTFACTOR as a possible solution.

Fixed at revision 9314.

Also note that I did not change the grep for errors in the log because we want the user to see the errors even if ignored.
