------- Comment #2 from dmueller@novell.com 2006-09-14 08:19 MST ------- actual output:
r = 34, buf = getgrgid_r: Numerical result out of range
expected output: r = 0, buf = suse

------- Comment #3 from pbaudis@novell.com 2006-09-14 08:48 MST ------- getgrgid_r does not return nonsense, it returns the error code for ERANGE, which is in sync with the documentation.
Of course, the error still shouldn't happen. Do you have any system/chroot at hand I could use to test it?

------- Comment #5 from pbaudis@novell.com 2006-09-22 08:15 MST ------- There is new glibc in BETA, could you please check with it? (Because I can't reproduce it with latest BETA glibc in chroot on another machine.) I'm reluctant to upgrade glibc on other people's machines. ;-)

------- Comment #8 from pbaudis@novell.com 2006-10-04 16:09 MST ------- The issue here is that the suse group has way too many members already and the resulting string is longer than _SC_GETGR_R_SIZE_MAX (1024), so getgrgid_r() asks for longer buffer by -ERANGE. This is obviously non-standard behaviour but the standard here makes no sense I believe and the only conforming implementation would have insanely high _SC_GETGR_R_SIZE_MAX. I have filed an Aardvark issue with OpenGroup and waiting for their feedback on the issue now. A possible workaround would be to raise _SC_GETGR_R_SIZE_MAX to say 16384 but I would prefer to avoid doing that unilaterally without some coordination with upstream.

------- Comment #9 from pbaudis@novell.com 2006-10-15 20:32 MST ------- BTW, is it just a generic problem or does it break some particular application? Given the situation I'd recommend patching the application so that it supports growing getgrgid_r() buffer at any rate.

------- Comment #10 from dmueller@novell.com 2006-10-16 03:55 MST ------- it breaks some unit tests in KDE 4.x I guess I'll have to patch it to retry with a bigger buffer.

--- Comment #12 from Petr Baudis pbaudis@novell.com 2008-12-04 16:47:00 MST --- Now, getgrgid_r() opengroup specification finally documents the ERANGE error and the behavior can be considered standard.
