Add enumeration logic for --drop-filtered. In --dry-run mode, print the OIDs of locally-held promisor blobs that exceed the filter threshold, as candidates for removal. Reading from write_filtered_pack() cannot work for partial clones. git repack routes promisor objects through a separate path: repack_promisor_objects() repacks them first, and the main pack-objects run uses --exclude-promisor-objects. By the time write_filtered_pack() runs, the promisor blobs are already consumed by the main pack. The filtered pack is always empty on a partial clone. Instead, walk promisor objects directly via odb_for_each_object() with ODB_FOR_EACH_OBJECT_PROMISOR_ONLY, collecting all promisor blobs into an oidset. The blobs exceeding the filter threshold are then selected using list_objects_filter__filter_oidset(). Every object enumerated this way is a promisor object, so it is recoverable from the promisor remote in the same sense as the rest of a partial clone, as long as the remote still has it. This holds without a separate is_promisor_object() check. A future implementation can verify availability against the remote directly once a client-side remote-object-info query exists. OBJECT_INFO_SKIP_FETCH_OBJECT is passed to every object info query so enumeration never triggers a lazy fetch. The enumeration collects candidates into a caller-provided oidset and --dry-run prints them. Actually removing the objects, together with the required promisor-remote verification, is written in a later commit.

Git - fast, scalable, distributed revision control system
Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.adoc to get started, then see
Documentation/giteveryday.adoc for a useful minimum set of commands, and
Documentation/git-<commandname>.adoc for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with man gittutorial or git help tutorial, and the
documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.adoc
(man gitcvs-migration or git help cvs-migration if git is
installed).
The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission and Documentation/CodingGuidelines).
Those wishing to help with error message, usage and informational message
string translations (localization l10) should see po/README.md
(a po file is a Portable Object file that holds the translations).
To subscribe to the list, send an email to git+subscribe@vger.kernel.org (see https://subspace.kernel.org/subscribing.html for details). The mailing list archives are available at https://lore.kernel.org/git/, https://marc.info/?l=git and other archival sites.
Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.
The maintainer frequently sends the "What's cooking" reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name "git" was given by Linus Torvalds when he wrote the very first version. He described the tool as "the stupid content tracker" and the name as (depending on your mood):
- random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant.
- stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang.
- "global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.
- "goddamn idiotic truckload of sh*t": when it breaks
