Currently we add a guess on top of the currently-allocated buffer size. When we re-use the buffer, it already has some memory allocated; adding to that means that we always grow the buffer regardless of how much we need to use. Instead, increase on top of the currently-used size. This still leaves us with the allocated size of the largest object we compress, but it's a minor pain compared to unbounded growth. This fixes #2285. --- src/zstream.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/zstream.c b/src/zstream.c index 85fa2e0e6..e75fb265e 100644 --- a/src/zstream.c +++ b/src/zstream.c @@ -134,7 +134,7 @@ int git_zstream_deflatebuf(git_buf *out, const void *in, size_t in_len) while (!git_zstream_done(&zs)) { size_t step = git_zstream_suggest_output_len(&zs), written; - if ((error = git_buf_grow(out, out->asize + step)) < 0) + if ((error = git_buf_grow(out, out->size + step)) < 0) goto done; written = out->asize - out->size;
