The point of these sections is generally to:
1. Give credit where it is due.
2. Give the reader an idea of where to ask questions or
file bug reports.
But they don't do a good job of either case. For (1), they
are out of date and incomplete. A much more accurate answer
can be gotten through shortlog or blame. For (2), the
correct contact point is generally git@vger, and even if you
wanted to cc the contact point, the out-of-date and
incomplete fields mean you're likely sending to somebody
useless.
So let's drop the fields entirely from all manpages except
git(1) itself. We already point people to the mailing list
for bug reports there, and we can update the Authors section
to give credit to the major contributors and point to
shortlog and blame for more information.
Each page has a "This is part of git" footer, so people can
follow that to the main git manpage.

NAME

|
git-reflog - Manage reflog information
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
'git reflog' <subcommand> <options>
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
The command takes various subcommands, and different options
|
|
depending on the subcommand:
|
|
|
|
[verse]
|
|
'git reflog expire' [--dry-run] [--stale-fix] [--verbose]
|
|
[--expire=<time>] [--expire-unreachable=<time>] [--all] <refs>...
|
|
'git reflog delete' ref@\{specifier\}...
|
|
'git reflog' ['show'] [log-options] [<ref>]
|
|
|
|
Reflog is a mechanism to record when the tip of branches are
|
|
updated. This command is to manage the information recorded in it.
|
|
|
|
The subcommand "expire" is used to prune older reflog entries.
|
|
Entries older than `expire` time, or entries older than
|
|
`expire-unreachable` time and not reachable from the current
|
|
tip, are removed from the reflog. This is typically not used
|
|
directly by the end users -- instead, see linkgit:git-gc[1].
|
|
|
|
The subcommand "show" (which is also the default, in the absence of any
|
|
subcommands) will take all the normal log options, and show the log of
|
|
the reference provided in the command-line (or `HEAD`, by default).
|
|
The reflog will cover all recent actions (HEAD reflog records branch switching
|
|
as well). It is an alias for `git log -g --abbrev-commit --pretty=oneline`;
|
|
see linkgit:git-log[1].
|
|
|
|
The reflog is useful in various git commands, to specify the old value
|
|
of a reference. For example, `HEAD@\{2\}` means "where HEAD used to be
|
|
two moves ago", `master@\{one.week.ago\}` means "where master used to
|
|
point to one week ago", and so on. See linkgit:gitrevisions[7] for
|
|
more details.
|
|
|
|
To delete single entries from the reflog, use the subcommand "delete"
|
|
and specify the _exact_ entry (e.g. "`git reflog delete master@\{2\}`").
|
|
|
|
|
|
OPTIONS
|
|
-------
|
|
|
|
--stale-fix::
|
|
This revamps the logic -- the definition of "broken commit"
|
|
becomes: a commit that is not reachable from any of the refs and
|
|
there is a missing object among the commit, tree, or blob
|
|
objects reachable from it that is not reachable from any of the
|
|
refs.
|
|
+
|
|
This computation involves traversing all the reachable objects, i.e. it
|
|
has the same cost as 'git prune'. Fortunately, once this is run, we
|
|
should not have to ever worry about missing objects, because the current
|
|
prune and pack-objects know about reflogs and protect objects referred by
|
|
them.
|
|
|
|
--expire=<time>::
|
|
Entries older than this time are pruned. Without the
|
|
option it is taken from configuration `gc.reflogExpire`,
|
|
which in turn defaults to 90 days.
|
|
|
|
--expire-unreachable=<time>::
|
|
Entries older than this time and not reachable from
|
|
the current tip of the branch are pruned. Without the
|
|
option it is taken from configuration
|
|
`gc.reflogExpireUnreachable`, which in turn defaults to
|
|
30 days.
|
|
|
|
--all::
|
|
Instead of listing <refs> explicitly, prune all refs.
|
|
|
|
--updateref::
|
|
Update the ref with the sha1 of the top reflog entry (i.e.
|
|
<ref>@\{0\}) after expiring or deleting.
|
|
|
|
--rewrite::
|
|
While expiring or deleting, adjust each reflog entry to ensure
|
|
that the `old` sha1 field points to the `new` sha1 field of the
|
|
previous entry.
|
|
|
|
--verbose::
|
|
Print extra information on screen.
