"git update-ref -d" and other operations to delete references did not leave any entry in HEAD's reflog when the reference being deleted was the current branch. This is not a problem in practice because you do not want to delete the branch you are currently on, but caused renaming of the current branch to something else not to be logged in a useful way. * km/delete-ref-reflog-message: branch: record creation of renamed branch in HEAD's log rename_ref: replace empty message in HEAD's log update-ref: pass reflog message to delete_ref() delete_ref: accept a reflog message argument

2017-02-20branch: record creation of renamed branch in HEAD's logLibravatar Kyle Meyer1-2/+2
Renaming the current branch adds an event to the current branch's log and to HEAD's log. However, the logged entries differ. The entry in the branch's log represents the entire renaming operation (the old and new hash are identical), whereas the entry in HEAD's log represents the deletion only (the new sha1 is null). Extend replace_each_worktree_head_symref(), whose only caller is branch_rename(), to take a reflog message argument. This allows the creation of the new ref to be recorded in HEAD's log. As a result, the renaming event is represented by two entries (a deletion and a creation entry) in HEAD's log. It's a bit unfortunate that the branch's log and HEAD's log now represent the renaming event in different ways. Given that the renaming operation is not atomic, the two-entry form is a more accurate representation of the operation and is more useful for debugging purposes if a failure occurs between the deletion and creation events. It would make sense to move the branch's log to the two-entry form, but this would involve changes to how the rename is carried out and to how the update flags and reflogs are processed for deletions, so it may not be worth the effort.

2017-02-20rename_ref: replace empty message in HEAD's logLibravatar Kyle Meyer1-1/+1
When the current branch is renamed, the deletion of the old ref is recorded in HEAD's log with an empty message. Now that delete_ref() accepts a reflog message, provide a more descriptive message by passing along the log message that is given to rename_ref(). The next step will be to extend HEAD's log to also include the second part of the rename, the creation of the new branch.

2017-02-20delete_ref: accept a reflog message argumentLibravatar Kyle Meyer1-3/+3
When the current branch is renamed with 'git branch -m/-M' or deleted with 'git update-ref -m<msg> -d', the event is recorded in HEAD's log with an empty message. In preparation for adding a more meaningful message to HEAD's log in these cases, update delete_ref() to take a message argument and pass it along to ref_transaction_delete(). Modify all callers to pass NULL for the new message argument; no change in behavior is intended. Note that this is relevant for HEAD's log but not for the deleted ref's log, which is currently deleted along with the ref. Even if it were not, an entry for the deletion wouldn't be present in the deleted ref's log. files_transaction_commit() writes to the log if REF_NEEDS_COMMIT or REF_LOG_ONLY are set, but lock_ref_for_update() doesn't set REF_NEEDS_COMMIT for the deleted ref because REF_DELETING is set. In contrast, the update for HEAD has REF_LOG_ONLY set by split_head_update(), resulting in the deletion being logged.

2017-02-13read_loose_refs(): read refs using resolve_ref_recursively()Libravatar Michael Haggerty2-14/+9
There is no need to call read_ref_full() or resolve_gitlink_ref() from read_loose_refs(), because we already have a ref_store object in hand. So we can call resolve_ref_recursively() ourselves. Happily, this unifies the code for the submodule vs. non-submodule cases. This requires resolve_ref_recursively() to be exposed to the refs subsystem, though not to non-refs code.

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 Weig2-5/+3
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).

2017-01-07files_transaction_commit(): clean up empty directoriesLibravatar Michael Haggerty2-8/+37
When deleting/pruning references, remove any directories that are made empty by the deletion of loose references or of reflogs. Otherwise such empty directories can survive forever and accumulate over time. (Even 'pack-refs', which is smart enough to remove the parent directories of loose references that it prunes, leaves directories that were already empty.) And now that files_transaction_commit() takes care of deleting the parent directories of loose references that it prunes, we don't have to do that in prune_ref() anymore. This change would be unwise if the *creation* of these directories could race with our deletion of them. But the earlier changes in this patch series made the creation paths robust against races, so now it is safe to tidy them up more aggressively.

Change log_ref_setup() to use raceproof_create_file() to create the new logfile. This makes it more robust against a race against another process that might be trying to clean up empty directories while we are trying to create a new logfile. This also means that it will only call create_leading_directories() if open() fails, which should be a net win. Even in the cases where we are willing to create a new logfile, it will usually be the case that the logfile already exists, or if not then that the directory containing the logfile already exists.

2016-10-10files_read_raw_ref: avoid infinite loop on broken symlinksLibravatar Jeff King1-1/+6
Our ref resolution first runs lstat() on any path we try to look up, because we want to treat symlinks specially (by resolving them manually and considering them symrefs). But if the results of `readlink` do _not_ look like a ref, we fall through to treating it like a normal file, and just read the contents of the linked path. Since fcb7c76 (resolve_ref_unsafe(): close race condition reading loose refs, 2013-06-19), that "normal file" code path will stat() the file and if we see ENOENT, will jump back to the lstat(), thinking we've seen inconsistent results between the two calls. But for a symbolic ref, this isn't a race: the lstat() found the symlink, and the stat() is looking at the path it points to. We end up in an infinite loop calling lstat() and stat(). We can fix this by avoiding the retry-on-inconsistent jump when we know that we found a symlink. While we're at it, let's add a comment explaining why the symlink case gets to this code in the first place; without that, it is not obvious that the correct solution isn't to avoid the stat() code path entirely.
