2018-07-20commit-reach: move can_all_from_reach_with_flagsLibravatar Derrick Stolee1-0/+14
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 can_all_from_reach_with_flags method is used in a stateful way by upload-pack.c. The parameters are very flexible, so we will be able to use its commit walking logic for many other callers.

2018-07-20commit-reach: move commit_contains from ref-filterLibravatar Derrick Stolee1-1/+19
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. All methods are direct moves, except we also make the commit_contains() method public so its consumers in ref-filter.c can still call it. We can also test this method in a test-tool in a later commit. Signed-off-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-07-20commit-reach: move ref_newer from remote.cLibravatar Derrick Stolee1-0/+2
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.

2018-07-20commit-reach: move walk methods from commit.cLibravatar Derrick Stolee1-0/+42
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 method declarations in commit.h are not touched by this commit and will be moved in a following commit. Many consumers need to point to commit-reach.h and that would bloat this commit.
