Subject: [PATCH v2] http*: cleanup slot->local after fclose
Date: Sun, 31 May 2009 17:54:13 +0800	[thread overview]
Message-ID: <20090531175413.962a55c3.rctay89@gmail.com> (raw)
In-Reply-To: <7vy6sdssnk.fsf@alter.siamese.dyndns.org>

Set slot->local to NULL after doing a fclose on the FILE* pointer it
points to.

This fixes the issue raised by Clemens Buchacher on 30th May:

I tested this on top of the first 4 patches in 'rc/http-push' in 'pu',
applied on 'maint'. [1] I wonder if this should instead be queued for
'pu' [2], since the issue only occurs there, although, conceivably, it
*could* happen without those patches in 'pu'.

Footnotes:
[1] You can find this in the 'http-cleanup-slot-local_maint branch' at
    git://github.com/rctay/git.git. It's quite a minimal testcase, if
    you're looking for one.

[2] Found in 'http-cleanup-slot-local_pu'.
