cocci: refactor common patterns to use xstrdup_or_null()

2016-10-12T18:22:10Z

d64ea0f83b ("git-compat-util: add xstrdup_or_null helper", 2015-01-12) added a handy wrapper that allows us to get a duplicate of a string or NULL if the original is NULL, but a handful of codepath predate its introduction or just weren't aware of it. Signed-off-by: Junio C Hamano

Merge branch 'nd/shallow-deepen'

2016-10-10T21:03:50Z

The existing "git fetch --depth=" option was hard to use correctly when making the history of an existing shallow clone deeper. A new option, "--deepen=", has been added to make this easier to use. "git clone" also learned "--shallow-since=" and "--shallow-exclude=" options to make it easier to specify "I am interested only in the recent N months worth of history" and "Give me only the history since that version". * nd/shallow-deepen: (27 commits) fetch, upload-pack: --deepen=N extends shallow boundary by N commits upload-pack: add get_reachable_list() upload-pack: split check_unreachable() in two, prep for get_reachable_list() t5500, t5539: tests for shallow depth excluding a ref clone: define shallow clone boundary with --shallow-exclude fetch: define shallow boundary with --shallow-exclude upload-pack: support define shallow boundary by excluding revisions refs: add expand_ref() t5500, t5539: tests for shallow depth since a specific date clone: define shallow clone boundary based on time with --shallow-since fetch: define shallow boundary with --shallow-since upload-pack: add deepen-since to cut shallow repos based on time shallow.c: implement a generic shallow boundary finder based on rev-list fetch-pack: use a separate flag for fetch in deepening mode fetch-pack.c: mark strings for translating fetch-pack: use a common function for verbose printing fetch-pack: use skip_prefix() instead of starts_with() upload-pack: move rev-list code out of check_non_tip() upload-pack: make check_non_tip() clean things up on error upload-pack: tighten number parsing at "deepen" lines ...

Merge branch 'bc/object-id'

2016-09-19T20:47:19Z

The "unsigned char sha1[20]" to "struct object_id" conversion continues. Notable changes in this round includes that ce->sha1, i.e. the object name recorded in the cache_entry, turns into an object_id. It had merge conflicts with a few topics in flight (Christian's "apply.c split", Dscho's "cat-file --filters" and Jeff Hostetler's "status --porcelain-v2"). Extra sets of eyes double-checking for mismerges are highly appreciated. * bc/object-id: builtin/reset: convert to use struct object_id builtin/commit-tree: convert to struct object_id builtin/am: convert to struct object_id refs: add an update_ref_oid function. sha1_name: convert get_sha1_mb to struct object_id builtin/update-index: convert file to struct object_id notes: convert init_notes to use struct object_id builtin/rm: convert to use struct object_id builtin/blame: convert file to use struct object_id Convert read_mmblob to take struct object_id. notes-merge: convert struct notes_merge_pair to struct object_id builtin/checkout: convert some static functions to struct object_id streaming: make stream_blob_to_fd take struct object_id builtin: convert textconv_object to use struct object_id builtin/cat-file: convert some static functions to struct object_id builtin/cat-file: convert struct expand_data to use struct object_id builtin/log: convert some static functions to use struct object_id builtin/blame: convert struct origin to use struct object_id builtin/apply: convert static functions to struct object_id cache: convert struct cache_entry to use struct object_id

Merge branch 'mh/ref-store'

2016-09-19T20:47:19Z

The ref-store abstraction was introduced to the refs API so that we can plug in different backends to store references. * mh/ref-store: (38 commits) refs: implement iteration over only per-worktree refs refs: make lock generic refs: add method to rename refs refs: add methods to init refs db refs: make delete_refs() virtual refs: add method for initial ref transaction commit refs: add methods for reflog refs: add method iterator_begin files_ref_iterator_begin(): take a ref_store argument split_symref_update(): add a files_ref_store argument lock_ref_sha1_basic(): add a files_ref_store argument lock_ref_for_update(): add a files_ref_store argument commit_ref_update(): add a files_ref_store argument lock_raw_ref(): add a files_ref_store argument repack_without_refs(): add a files_ref_store argument refs: make peel_ref() virtual refs: make create_symref() virtual refs: make pack_refs() virtual refs: make verify_refname_available() virtual refs: make read_raw_ref() virtual ...

refs: add method to rename refs

2016-09-09T22:28:14Z

This removes the last caller of function get_files_ref_store(), so remove it. Signed-off-by: David Turner Signed-off-by: Junio C Hamano Signed-off-by: Michael Haggerty Signed-off-by: Junio C Hamano

refs: add methods to init refs db

2016-09-09T22:28:14Z

Alternate refs backends might not need the refs/heads directory and so on, so we make ref db initialization part of the backend. Signed-off-by: David Turner Signed-off-by: Junio C Hamano Signed-off-by: Michael Haggerty Signed-off-by: Junio C Hamano

refs: make delete_refs() virtual

2016-09-09T22:28:14Z

In the file-based backend, delete_refs has some special optimization to deal with packed refs. In other backends, we might be able to make ref deletion faster by putting all deletions into a single transaction. So we need a special backend function for this.

refs: add methods for reflog

2016-09-09T22:28:13Z

In the file-based backend, the reflog piggybacks on the ref lock. Since other backends won't have the same sort of ref lock, ref backends must also handle reflogs.
