git/remote.h, branch v2.20.2

Merge branch 'ds/reachable'

2018-09-17T20:53:52Z

The code for computing history reachability has been shuffled, obtained a bunch of new tests to cover them, and then being improved. * ds/reachable: commit-reach: correct accidental #include of C file commit-reach: use can_all_from_reach commit-reach: make can_all_from_reach... linear commit-reach: replace ref_newer logic test-reach: test commit_contains test-reach: test can_all_from_reach_with_flags test-reach: test reduce_heads test-reach: test get_merge_bases_many test-reach: test is_descendant_of test-reach: test in_merge_bases test-reach: create new test tool for ref_newer commit-reach: move can_all_from_reach_with_flags upload-pack: generalize commit date cutoff upload-pack: refactor ok_to_give_up() upload-pack: make reachable() more generic commit-reach: move commit_contains from ref-filter commit-reach: move ref_newer from remote.c commit.h: remove method declarations commit-reach: move walk methods from commit.c

Add missing includes and forward declarations

2018-08-15T18:52:09Z

I looped over the toplevel header files, creating a temporary two-line C program for each consisting of #include "git-compat-util.h" #include $HEADER This patch is the result of manually fixing errors in compiling those tiny programs. Signed-off-by: Elijah Newren Signed-off-by: Junio C Hamano

commit-reach: move ref_newer from remote.c

2018-07-20T22:38:54Z

There are several commit walks in the codebase. Group them together into a new commit-reach.c file and corresponding header. After we group these walks into one place, we can reduce duplicate logic by calling equivalent methods. The ref_newer() method is used by 'git push -f' to check if a force-push is necessary. By making the method public, we make it possible to test the method directly without setting up an envieronment where a 'git push' call makes sense.

fetch-pack: implement ref-in-want

2018-06-28T16:33:30Z

Implement ref-in-want on the client side so that when a server supports the "ref-in-want" feature, a client will send "want-ref" lines for each reference the client wants to fetch. This feature allows clients to tolerate inconsistencies that exist when a remote repository's refs change during the course of negotiation. This allows a client to request to request a particular ref without specifying the OID of the ref. This means that instead of hitting an error when a ref no longer points at the OID it did at the beginning of negotiation, negotiation can continue and the value of that ref will be sent at the termination of negotiation, just before a packfile is sent. More information on the ref-in-want feature can be found in Documentation/technical/protocol-v2.txt. Signed-off-by: Brandon Williams Signed-off-by: Junio C Hamano

Merge branch 'bw/ref-prefix-for-configured-refspec'

2018-05-30T12:51:26Z

"git fetch $there $refspec" that talks over protocol v2 can take advantage of server-side ref filtering; the code has been extended so that this mechanism triggers also when fetching with configured refspec. * bw/ref-prefix-for-configured-refspec: (38 commits) fetch: generate ref-prefixes when using a configured refspec refspec: consolidate ref-prefix generation logic submodule: convert push_unpushed_submodules to take a struct refspec remote: convert check_push_refs to take a struct refspec remote: convert match_push_refs to take a struct refspec http-push: store refspecs in a struct refspec transport: remove transport_verify_remote_names send-pack: store refspecs in a struct refspec transport: convert transport_push to take a struct refspec push: convert to use struct refspec push: check for errors earlier remote: convert match_explicit_refs to take a struct refspec remote: convert get_ref_match to take a struct refspec remote: convert query_refspecs to take a struct refspec remote: convert apply_refspecs to take a struct refspec remote: convert get_stale_heads to take a struct refspec fetch: convert prune_refs to take a struct refspec fetch: convert get_ref_map to take a struct refspec fetch: convert do_fetch to take a struct refspec refspec: remove the deprecated functions ...
