About This Patch:
-----------------
This patch has almost no reuse of previous patch's commits, because this
one redesigned the exclusion for various object types and reoganized the
commits.
Commit (1): objects.c: introduce `exclude_level` enum
This commit introduce a new enum named `exclude_level` in object.c, it
contains three enumerated values: "ET_SELF", "ET_INCLUDE" and
"ET_REACHABLE". The commit only makes the definitions, without any
implementations.
Commit (2): Introduce function `match_packfile_uri_exclusions`
This one move the codes used for matching the URI protocols from
`want_found_object` to new function `match_packfile_uri_exclusions`. The
purpose is to improve code readability related to the feature and make
preparation for further extension about the matching and exclusion for
multiple object types.
Commit (3): Replace `show_data` with structure `show_info`
There is no feature related codes in this commit. This commit modified
the parameters in function `show_object` by replacing `show_data` with a
new structure `show_info`, this is another way of implementation about
the previous commit[1] in patch v5.
Commit (4): Introduce `uploadpack.excludeobject` configuration
This commit introduce a new and backward-compatible configuration named
`uploadpack.excludeobject`, the diff between old and new:
uploadpack.blobPackfileUri=<object-hash> <pack-hash> <uri>
uploadpack.excludeobject=<object-hash> <level> <pack-hash> <uri>
The <level> is correspond to the exclusion scope of the given object,
and it's mentioned as `exclude_value` in object.c by "Commit (1)".
Commit (6,8,10): Implementations for excluding commits, trees and tags
Commit (7,9,11): Tests for excluding excluding commits, trees and tags
Commit (12): Corresponding documentation modifications
bundle-uri And packfile-uri
----------------------------
Ævar Arnfjörð Bjarmason post a new feature patchset[2] named "bundle-uri",
it supports to let client download the full or incremental bundles
directly without any negotiations with the server (full clone first and
in a MVP progress now). I'm sorry if I misleading the meanings and
please point it out.
In "packfile-uri", different with "bundle-uri", happens in the span of
packing objects during git-upload-pack on the server. This is an
experimental feature, originally designed as a CDN for large BLOB
objects, but it's not yet fully functional. I'm currently working on it
for making it support other types of objects.
I also noticed that some opinions about the two features are mentioned
in the patch[2], so I cc to Stolee in this patch, I hope I did not
disturb you.
