[PATCH v4 0/4] pack-bitmap.c: avoid exposing absolute paths

From: Teng Long <dyroneteng@gmail.com>

Sorry for relying late, Taylor..

Diff since v3:

I picked Peff's two new constructive patches[1] which I think are meaningful. Peff also mentioned whether to design a "GIT_TRACE2_BITMAP" ENV to help debugging bitmap, and I think it's very interesting but maybe it's a bigger scale on current patchset, so I prefer to do it in another series.

Thanks.

Jeff King (2):
  pack-bitmap.c: break out of the bitmap loop early if not tracing
  pack-bitmap.c: trace bitmap ignore logs when midx-bitmap is found

Teng Long (2):
  pack-bitmap.c: remove unnecessary "open_pack_index()" calls
  pack-bitmap.c: avoid exposing absolute paths
