Summary

0004314: glob() fails to reset errno for !UCLIBC_HAS_GNU_GLOB

Description

My setup is as follows:-

Atmel AVR32 NGW100 dev kit
buildroot (using uclibc 0.9.29)

The problem:-

The glob() function appears to get confused by any existing errno value, rather than resetting it back to 0 and generating its own error value.

The attached code demonstrates the problem.

If the line "errno = 0;" is removed, then glob() appears to fail.

In fact, if errno is set to anything other than 0, then glob() returns with error 2.

Notes
(0010344) mpfj 08-08-08 03:47	Any update on this ?

(0010354) mpfj 08-08-08 06:56	This is now fixed. It would appear that I had to enable an extra feature (UCLIBC_HAS_GNU_GLOB) to obtain the correct functionality.

(0012374) bernhardf 09-29-08 05:55	Unfortunately i cannot reproduce this on i386. Can you provide an "ls /etc/avahi/services/*.service" and the exact failure you get when you set errno=9 (instead of 0)? Don't forget to disable GNU_GLOB for these tests. TIA

(0012384) bernhardf 09-29-08 05:57	oh, and please try this with uClibc trunk, too. We believe this is fixed there.

(0012544) egtvedt 10-01-08 05:37	Tested with uClibc trunk (0.9.30-rc ish) and glob works. Both with and without UCLIBC_HAS_GNU_GLOB set in uClibc configuration.
