[PATCH 0/6] detect dumb HTTP pack file corruption

This series tries to better detect and avoid corrupted pack and idx files downloaded over the dumb HTTP transport. It addresses the GitHub repository maintainence causing corruption issue reported today by Christian Halstrick.

Shawn O. Pearce (6):
  http.c: Remove bad free of static block
  t5550-http-fetch: Use subshell for repository operations
  http.c: Tiny refactoring of finish_http_pack_request
  http.c: Drop useless != NULL test in finish_http_pack_request
  http-fetch: Use index-pack rather than verify-pack to check packs
  http-fetch: Use temporary files for pack-*.idx until verified
