Subject: [PATCH] git-local-fetch: Avoid calling close(-1)
X-Git-Tag: v0.99.7c~2^2~4
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=1a951815ddaa4e4b570cc67e204f45e9a12841e0;p=git.git

[PATCH] git-local-fetch: Avoid calling close(-1)

After open() failure, copy_file() called close(ifd) with ifd == -1
(harmless, but causes Valgrind noise).  The same thing was possible
for the destination file descriptor.
