From: Linus Torvalds Date: Thu, 26 May 2005 01:25:08 +0000 (-0700) Subject: unpack_sha1_file: zero-pad the unpacked object. X-Git-Tag: v0.99~457 X-Git-Url: https://git.octo.it/?a=commitdiff_plain;h=e871b649a3f4ede26eb98c7d46df7acdc7ecbe81;p=git.git unpack_sha1_file: zero-pad the unpacked object. This makes them easier to parse without having to worry about running off the end, and allows us to treat commits as normal strings. --- diff --git a/sha1_file.c b/sha1_file.c index e6fdaa21..ac7bf9fd 100644 --- a/sha1_file.c +++ b/sha1_file.c @@ -329,7 +329,7 @@ void * unpack_sha1_file(void *map, unsigned long mapsize, char *type, unsigned l return NULL; bytes = strlen(buffer) + 1; - buf = xmalloc(*size); + buf = xmalloc(1+*size); memcpy(buf, buffer + bytes, stream.total_out - bytes); bytes = stream.total_out - bytes; @@ -339,6 +339,7 @@ void * unpack_sha1_file(void *map, unsigned long mapsize, char *type, unsigned l while (inflate(&stream, Z_FINISH) == Z_OK) /* nothing */; } + buf[*size] = 0; inflateEnd(&stream); return buf; }
