From 162eb5f838630f75f78f26d28b46b02781724b7d Mon Sep 17 00:00:00 2001 From: "Shawn O. Pearce" Date: Mon, 19 Apr 2010 07:23:05 -0700 Subject: [PATCH] http.c: Remove unnecessary strdup of sha1_to_hex result Most of the time the dumb HTTP transport is run without the verbose flag set, so we only need the result of sha1_to_hex(sha1) once, to construct the pack URL. Don't bother with an unnecessary malloc, copy, free chain of this buffer. If verbose is set, we'll format the SHA-1 twice now. But this tiny extra CPU time spent is nothing compared to the slowdown that is usually imposed by the verbose messages being sent to the tty, and is entirely trivial compared to the latency involved with the remote HTTP server sending something as big as a pack file.
