From e871b649a3f4ede26eb98c7d46df7acdc7ecbe81 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Wed, 25 May 2005 18:25:08 -0700 Subject: [PATCH] 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. --- sha1_file.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/sha1_file.c b/sha1_file.c index e6fdaa217..ac7bf9fd2 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; } -- 2.26.2
