refs: add option core.logAllRefUpdates = always

2017-01-31T18:01:24Z

When core.logallrefupdates is true, we only create a new reflog for refs that are under certain well-known hierarchies. The reason is that we know that some hierarchies (like refs/tags) are not meant to change, and that unknown hierarchies might not want reflogs at all (e.g., a hypothetical refs/foo might be meant to change often and drop old history immediately). However, sometimes it is useful to override this decision and simply log for all refs, because the safety and audit trail is more important than the performance implications of keeping the log around. This patch introduces a new "always" mode for the core.logallrefupdates option which will log updates to everything under refs/, regardless where in the hierarchy it is (we still will not log things like ORIG_HEAD and FETCH_HEAD, which are known to be transient).

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

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.
