2017-02-03Merge branch 'cw/log-updates-for-all-refs-really'Libravatar Junio C Hamano1-4/+7
The "core.logAllRefUpdates" that used to be boolean has been enhanced to take 'always' as well, to record ref updates to refs other than the ones that are expected to be updated (i.e. branches, remote-tracking branches and notes). * cw/log-updates-for-all-refs-really: doc: add note about ignoring '--no-create-reflog' update-ref: add test cases for bare repository refs: add option core.logAllRefUpdates = always config: add markup to core.logAllRefUpdates doc
2017-01-31refs: add option core.logAllRefUpdates = alwaysLibravatar Cornelius Weig1-4/+7
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).

2016-12-07hold_locked_index(): align error handling with hold_lockfile_for_update()Libravatar Junio C Hamano1-2/+2
Callers of the hold_locked_index() function pass 0 when they want to prepare to write a new version of the index file without wishing to die or emit an error message when the request fails (e.g. somebody else already held the lock), and pass 1 when they want the call to die upon failure. This option is called LOCK_DIE_ON_ERROR by the underlying lockfile API, and the hold_locked_index() function translates the paramter to LOCK_DIE_ON_ERROR when calling the hold_lock_file_for_update(). Replace these hardcoded '1' with LOCK_DIE_ON_ERROR and stop translating. Callers other than the ones that are replaced with this change pass '0' to the function; no behaviour change is intended with this patch. Signed-off-by: Junio C Hamano <gitster@pobox.com> --- Among the callers of hold_locked_index() that passes 0: - diff.c::refresh_index_quietly() at the end of "git diff" is an opportunistic update; it leaks the lockfile structure but it is just before the program exits and nobody should care. - builtin/describe.c::cmd_describe(), builtin/commit.c::cmd_status(), sequencer.c::read_and_refresh_cache() are all opportunistic updates and they are OK. - builtin/update-index.c::cmd_update_index() takes a lock upfront but we may end up not needing to update the index (i.e. the entries may be fully up-to-date), in which case we do not need to issue an error upon failure to acquire the lock. We do diagnose and die if we indeed need to update, so it is OK. - wt-status.c::require_clean_work_tree() IS BUGGY. It asks silence, does not check the returned value. Compare with callsites like cmd_describe() and cmd_status() to notice that it is wrong to call update_index_if_able() unconditionally.

2016-11-09create_branch: drop unused "head" parameterLibravatar Jeff King1-1/+1
This function used to have the caller pass in the current value of HEAD, in order to make sure we didn't clobber HEAD. In 55c4a6730, that logic moved to validate_new_branchname(), which just resolves HEAD itself. The parameter to create_branch is now unused. Since we have to update and re-wrap the docstring describing the parameters anyway, let's take this opportunity to break it out into a list, which makes it easier to find the parameters.

2016-08-01merge_trees(): ensure that the callers release output bufferLibravatar Johannes Schindelin1-0/+1
The recursive merge machinery accumulates its output in an output buffer, to be flushed at the end of merge_recursive(). At this point, we forgot to release the output buffer. When calling merge_trees() (i.e. the non-recursive part of the recursive merge) directly, the output buffer is never flushed because the caller may be merge_recursive() which wants to flush the output itself. For the same reason, merge_trees() cannot release the output buffer: it may still be needed. Forgetting to release the output buffer did not matter much when running git-checkout, or git-merge-recursive, because we exited after the operation anyway. Ever since cherry-pick learned to pick a commit range, however, this memory leak had the potential of becoming a problem.

2016-07-26prepare the builtins for a libified merge_recursive()Libravatar Johannes Schindelin1-1/+3
Previously, callers of merge_trees() or merge_recursive() expected that code to die() with an error message. This used to be okay because we called those commands from scripts, and had a chance to print out a message in case the command failed fatally (read: with exit code 128). As scripting incurs its own set of problems (portability, speed, idiosyncrasies of different shells, limited data structures leading to inefficient code), we are converting more and more of these scripts into builtins, using library functions directly. We already tried to use merge_recursive() directly in the builtin git-am, for example. Unfortunately, we had to roll it back temporarily because some of the code in merge-recursive.c still deemed it okay to call die(), when the builtin am code really wanted to print out a useful advice after the merge failed fatally. In the next commits, we want to fix that. The code touched by this commit expected merge_trees() to die() with some useful message when there is an error condition, but merge_trees() is going to be improved by converting all die() calls to return error() instead (i.e. return value -1 after printing out the message as before), so that the caller can react more flexibly. This is a step to prepare for the version of merge_trees() that no longer dies, even if we just imitate the previous behavior by calling exit(128): this is what callers of e.g. `git merge` have come to expect. Note that the callers of the sequencer (revert and cherry-pick) already fail fast even for the return value -1; The only difference is that they now get a chance to say "<command> failed". A caller of merge_trees() might want handle error messages themselves (or even suppress them). As this patch is already complex enough, we leave that change for a later patch.

2016-04-22worktree.c: check whether branch is rebased in another worktreeLibravatar Nguyễn Thái Ngọc Duy1-1/+1
This function find_shared_symref() is used in a couple places: 1) in builtin/branch.c: it's used to detect if a branch is checked out elsewhere and refuse to delete the branch. 2) in builtin/notes.c: it's used to detect if a note is being merged in another worktree 3) in branch.c, the function die_if_checked_out() is actually used by "git checkout" and "git worktree add" to see if a branch is already checked out elsewhere and refuse the operation. In cases 1 and 3, if a rebase is ongoing, "HEAD" will be in detached mode, find_shared_symref() fails to detect it and declares "no branch is checked out here", which is not really what we want. This patch tightens the test. If the given symref is "HEAD", we try to detect if rebase is ongoing. If so return the branch being rebased. This makes checkout and branch delete operations safer because you can't checkout a branch being rebased in another place, or delete it. Special case for checkout. If the current branch is being rebased, git-rebase.sh may use "git checkout" to abort and return back to the original branch. The updated test in find_shared_symref() will prevent that and "git rebase --abort" will fail as a result. find_shared_symref() and die_if_checked_out() have to learn a new option ignore_current_worktree to loosen the test a bit.

2016-02-10check_filename: tighten dwim-wildcard ambiguityLibravatar Jeff King1-1/+2
When specifying both revisions and pathnames, we allow "<rev> -- <pathspec>" to be spelled without the "--" as long as it is not ambiguous. The original logic was something like: 1. Resolve each item with get_sha1(). If successful, we know it can be a <rev>. Verify that it _isn't_ a filename, using verify_non_filename(), and complain of ambiguity otherwise. 2. If get_sha1() didn't succeed, make sure that it _is_ a file, using verify_filename(). If not, complain that it is neither a <rev> nor a <pathspec>. Both verify_filename() and verify_non_filename() rely on check_filename(), which definitely said "yes, this is a file" or "no, it is not" using lstat(). Commit 28fcc0b (pathspec: avoid the need of "--" when wildcard is used, 2015-05-02) introduced a convenience feature: check_filename() will consider anything with wildcard meta-characters as a possible filename, without even checking the filesystem. This works well for case 2. For such a wildcard, we would previously have died and said "it is neither". Post-28fcc0b, we assume it's a pathspec and proceed. But it makes some instances of case 1 worse. We may have an extended sha1 expression that contains meta-characters (e.g., "HEAD^{/foo.*bar}"), and we now complain that it's also a filename, due to the wildcard characters (even though that wildcard would not match anything in the filesystem). One solution would be to actually expand the pathname and see if it matches anything on the filesystem. But that's potentially expensive, and we do not have to be so rigorous for this DWIM magic (if you want rigor, use "--"). Instead, we can just use different rules for cases 1 and 2. When we know something is a rev, we will complain only if it meets a much higher standard for "this is also a file"; namely that it actually exists in the filesystem. Case 2 remains the same: we use the looser "it could be a filename" standard introduced by 28fcc0b. We can accomplish this by pulling the wildcard logic out of check_filename() and putting it into verify_filename(). Its partner verify_non_filename() does not need a change, since check_filename() goes back to implementing the "higher standard". Besides these two callers of check_filename(), there is one other: git-checkout does a similar DWIM itself. It hits this code path only after get_sha1() has returned failure, making it case 2, which gets the special wildcard treatment. Note that we drop the tests in t2019 in favor of a more complete set in t6133. t2019 was not the right place for them (it's about refname ambiguity, not dwim parsing ambiguity), and the second test explicitly checked for the opposite result of the case we are fixing here (which didn't really make any sense; as shown by the test_must_fail in the test, it would only serve to annoy people).

The "new-worktree-mode" hack in "checkout" that was added in nd/multiple-work-trees topic has been removed by updating the implementation of new "worktree add". * es/worktree-add-cleanup: (25 commits) Documentation/git-worktree: fix duplicated 'from' Documentation/config: mention "now" and "never" for 'expire' settings Documentation/git-worktree: fix broken 'linkgit' invocation checkout: drop intimate knowledge of newly created worktree worktree: populate via "git reset --hard" rather than "git checkout" worktree: avoid resolving HEAD unnecessarily worktree: make setup of new HEAD distinct from worktree population worktree: detect branch-name/detached and error conditions locally worktree: add_worktree: construct worktree-population command locally worktree: elucidate environment variables intended for child processes worktree: make branch creation distinct from worktree population worktree: add: suppress auto-vivication with --detach and no <branch> worktree: make --detach mutually exclusive with -b/-B worktree: introduce options container worktree: simplify new branch (-b/-B) option checking worktree: improve worktree setup message branch: publish die_if_checked_out() checkout: teach check_linked_checkout() about symbolic link HEAD checkout: check_linked_checkout: simplify symref parsing checkout: check_linked_checkout: improve "already checked out" aesthetic ...
2015-08-03Merge branch 'dt/refs-backend-preamble'Libravatar Junio C Hamano1-12/+10
In preparation for allowing different "backends" to store the refs in a way different from the traditional "one ref per file in $GIT_DIR or in a $GIT_DIR/packed-refs file" filesystem storage, reduce direct filesystem access to ref-like things like CHERRY_PICK_HEAD from scripts and programs. * dt/refs-backend-preamble: git-stash: use update-ref --create-reflog instead of creating files update-ref and tag: add --create-reflog arg refs: add REF_FORCE_CREATE_REFLOG flag git-reflog: add exists command refs: new public ref function: safe_create_reflog refs: break out check for reflog autocreation refs.c: add err arguments to reflog functions
2015-07-21refs: new public ref function: safe_create_reflogLibravatar David Turner1-9/+5
The safe_create_reflog function creates a reflog, if it does not already exist. The log_ref_setup function becomes private and gains a force_create parameter to force the creation of a reflog even if log_all_ref_updates is false or the refname is not one of the special refnames. The new parameter also reduces the need to store, modify, and restore the log_all_ref_updates global before reflog creation. In a moment, we will use this to add reflog creation commands to git-reflog. Signed-off-by: David Turner <dturner@twopensource.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-07-21refs.c: add err arguments to reflog functionsLibravatar David Turner1-3/+5
Add an err argument to log_ref_setup that can explain the reason for a failure. This then eliminates the need to manage errno through this function since we can just add strerror(errno) to the err string when meaningful. No callers relied on errno from this function for anything else than the error message. Also add err arguments to private functions write_ref_to_lockfile, log_ref_write_1, commit_ref_update. This again eliminates the need to manage errno in these functions. Some error messages are slightly reordered. Update of a patch by Ronnie Sahlberg.

2015-07-20checkout: drop intimate knowledge of newly created worktreeLibravatar Eric Sunshine1-7/+2
Now that git-worktree no longer relies upon git-checkout for new branch creation, new worktree HEAD set up, or initial worktree population, git-checkout no longer needs intimate knowledge that it may be operating in a newly created worktree. Therefore, drop 'new_worktree_mode' and the private GIT_CHECKOUT_NEW_WORKTREE environment variable by which git-worktree communicated to git-checkout that it was being invoked to manipulate a new worktree. This reverts the remaining changes to checkout.c by 529fef2 (checkout: support checking out into a new working directory, 2014-11-30).
