negative-refspec: improve comment on query_matches_negative_refspec

2020-12-22T06:49:36Z

Comment did not adequately explain how the two loops work together to achieve the goal of querying for matching of any negative refspec. Signed-off-by: Nipunn Koorapati Signed-off-by: Junio C Hamano

negative-refspec: fix segfault on : refspec

2020-12-22T06:49:36Z

The logic added to check for negative pathspec match by c0192df630 (refspec: add support for negative refspecs, 2020-09-30) looks at refspec->src assuming it is never NULL, however when remote.origin.push is set to ":", then refspec->src is NULL, causing a segfault within strcmp. Tell git to handle matching refspec by adding the needle to the set of positively matched refspecs, since matching ":" refspecs match anything as src. Add test for matching refspec pushes fetch-negative-refspec both individually and in combination with a negative refspec. Signed-off-by: Nipunn Koorapati Signed-off-by: Junio C Hamano

get_default_branch_name(): prepare for showing some advice

2020-12-13T23:53:50Z

We are about to introduce a message giving users running `git init` some advice about `init.defaultBranch`. This will necessarily be done in `repo_default_branch_name()`. Not all code paths want to show that advice, though. In particular, the `git clone` codepath _specifically_ asks for `init_db()` to be quiet, via the `INIT_DB_QUIET` flag. In preparation for showing users above-mentioned advice, let's change the function signature of `get_default_branch_name()` to accept the parameter `quiet`.

Commit 6dc905d974 (config: split repo scope to local and worktree, 2020-02-10) made some "if" statements multiline, but didn't indent the second lines in our usual way. Signed-off-by: Jeff King Signed-off-by: Junio C Hamano

Merge branch 'sk/force-if-includes'

2020-10-27T22:09:49Z

"git push --force-with-lease[=]" can easily be misused to lose commits unless the user takes good care of their own "git fetch". A new option "--force-if-includes" attempts to ensure that what is being force-pushed was created after examining the commit at the tip of the remote ref that is about to be force-replaced. * sk/force-if-includes: t, doc: update tests, reference for "--force-if-includes" push: parse and set flag for "--force-if-includes" push: add reflog check for "--force-if-includes"

push: add reflog check for "--force-if-includes"

2020-10-03T16:59:18Z

Add a check to verify if the remote-tracking ref of the local branch is reachable from one of its "reflog" entries. The check iterates through the local ref's reflog to see if there is an entry for the remote-tracking ref and collecting any commits that are seen, into a list; the iteration stops if an entry in the reflog matches the remote ref or if the entry timestamp is older the latest entry of the remote ref's "reflog". If there wasn't an entry found for the remote ref, "in_merge_bases_many()" is called to check if it is reachable from the list of collected commits. When a local branch that is based on a remote ref, has been rewound and is to be force pushed on the remote, "--force-if-includes" runs a check that ensures any updates to the remote-tracking ref that may have happened (by push from another repository) in-between the time of the last update to the local branch (via "git-pull", for instance) and right before the time of push, have been integrated locally before allowing a forced update. If the new option is passed without specifying "--force-with-lease", or specified along with "--force-with-lease=:" it is a "no-op". Signed-off-by: Srinidhi Kaushik Signed-off-by: Junio C Hamano
