[PATCH v5 0/4] pack-bitmap.c: avoid exposing absolute paths

From: Teng Long <dyroneteng@gmail.com>

Changes since v4:

* [3/4] Reroll the commit message.
* [4/4] Reroll the commit message and remove the initialization of 'found'.

Besides of 3/4 and 4/4, the 1/4 and 2/4 seem already in 'next' as 8ddc06631b184e6f43051f7ea8ac9bbc86817127 and 2aa84d5f3ea1966a81477ad31bee0136e39d3917 , but I send again here just for the completeness of the patchset, I think it will be nice to merge Peff's commits of there are no new suggestions.

Thanks.

         pack-bitmap.c: break out of the bitmap loop early if not tracing
     
    -    When we successfully open a bitmap, we will continue to try to open
    -    other packs, and when trace2 is enabled, we will report any subsequent
    -    bitmap ignored information in the log. So when we find that trace2 is
    -    not enabled, we can actually terminate the loop early.
    +    After opening a bitmap successfully, we try opening others only
    +    because we want to report that other bitmap files are ignored in
    +    the trace2 log.  When trace2 is not enabled, we do not have to
    +    do any of that.

    -    We retained pack bitmaps as a quick recovery mechanism while
    -    test-deploying midx bitmaps. This is an internal mechanism, and we
    -    want to expose this rule externally through trace2 so that end users,
    -    repo-maintainers, and debuggers know what is happening in the process.
    +    When we find a midx bitmap, we do not bother checking for pack
    +    bitmaps, since we can use only one. But since we will warn of unused
    +    bitmaps via trace2, let's continue looking for pack bitmaps when
    +    tracing is enabled.
