Subject: [PATCH 0/1] pack-bitmap.c: avoid exposing absolute paths
Date: Fri, 26 Aug 2022 15:09:11 +0800	[thread overview]
Message-ID: <20220826070912.70274-1-dyroneteng@gmail.com> (raw)

This patch tries to avoid the problem of leaking sensitive information that
could output the absolute path of the repository when try to open multiple
bitmaps. For example, in "alternates" scenario, where the repository
"alternate_repo" serves as alternate object stores for repository
"want_to_borrow" , and each of both has it's own bitmap file, then we run
`git rev-list --use-bitmap-index HEAD`, the output might be:

  $ cd want_to_borrow.git
  $ git rev-list --test-bitmap HEAD
  warning: ignoring extra bitmap file: /Users/tenglong.tl/Downloads/alternate_repo.git/.git/objects/pack/pack-bff67e2a7a154e6933afe61b3681726cf9bd8e8b.pack
  Bitmap v1 test (1 entries loaded)
  Found bitmap for 30f146d41a7a86930fae3f4a5e1f1c1f2bfacbba. 64 bits / 11030517 checksum
  Verifying bitmap entries: 100% (3/3), done.
  OK!

After apply this patch:

  $ git rev-list --test-bitmap HEAD
  warning: ignoring extra bitmap files
  Bitmap v1 test (1 entries loaded)
  Found bitmap for 30f146d41a7a86930fae3f4a5e1f1c1f2bfacbba. 64 bits / 11030517 checksum
  Verifying bitmap entries: 100% (3/3), done.
  OK!

Thanks.
