Previously git-describe would output lines of the form
v1.1.1-gf509d56
The update hook found the dash and stripped it off using
sed 's/-g.*//'
The remainder was then used as the previous tag name.
However, git-describe has changed format. The output is now of the form
v1.1.1-23-gf509d56
The above sed fragment doesn't strip the middle "-23", and so the
previous tag name used would be "v1.1.1-23". This is incorrect.
Since the hook script was written, git-describe now gained support for
"--abbrev=0", which it uses as a special flag to tell it not to output
anything other than the nearest tag name. This patch fixes the problem,
and prevents any future recurrence by using this new flag rather than
sed to find the previous tag.

Instead of using antiquated "git-rev-parse | git-rev-list"
pipeline, it is easier to use "git-rev-list" or "git-log" these
days, as Linus points out.
While we are at it, fix the typo on variable name $newref that
should be $newrev.

44478d99ee introduced a filter using "git-rev-parse --not --all" to the
log display to prevent the display of revisions already in the
repository. However, the table of contents generation didn't get that
same update.
This patch fixes that. The table of contents before the log and the log
now both display the same list of revisions.

If you were issuing emails for two branches, and one merged the other,
you would get the same log messages appearing in two separate emails.
e.g. A working repository, where the last push to central was done at
the revision marked "B", after which two branches were developed
further.
* -- B -- 1 -- 1 -- M (branch1)
\ /
2 -- 2 -- 2 (branch2)
Now imagine that branch2 is pushed to the email-generating repository;
an email containing all the "2" revisions would be sent. Now, let's say
branch1 is pushed, the old update hook would run
git-rev-list $newrev ^$baserev
Where $newrev would be "M" and $baserev would be "B". This list
includes all the "2" revisions as well as all the "1" revisions.
This patch addresses this problem by using
git-rev-parse --not --all | git-rev-list --stdin $newrev ^$baserev
To inhibit the display of all revisions that are already in the
repository.

In a repository with a large number of refs, the following command line
could easily overflow the command line size limitations
git-rev-list $newref $(git-rev-parse --not --all)
Fortunately, git-rev-list already has the means to cope with this
situation with the --stdin switch
git-rev-parse --not --all | git-rev-list --stdin $newref
Which is exactly what this patch does.

I know it's only an example, but having this might save someone else the
trouble of writing an enhanced version for themselves.
It basically does the same job as the old update hook, but with these
differences:
* The recipients list is read from the repository config file from
hooks.mailinglist
* Updating unannotated tags can be allowed by setting
hooks.allowunannotated
* Announcement emails (via annotated tag creation) can be sent to a
different mailing list by setting hooks.announcelist
* Output email is more verbose and generates specific content depending
on whether the ref is a tag, an annotated tag, a branch, or a
tracking branch
* The email is easier to filter; the subject line is prefixed with
[SCM] and a project description pulled from the "description" file
* It catches (and displays differently) branch updates that are
performed with a --force
Obviously, it's nothing that clever - it's the update hook I use on my
repositories but I've tried to keep it general, and tried to make the
output always relevant to the type of update.

I got bitten because in the UK (where one would expect 1970-01-01 00:00
to be UTC 0) some politicians decided to mess around with daylight
savings time from 1968 to 1971; it was permanently BST (+0100). That
means that on my computer the following is true:
$ date --date="1970-01-01 00:00" +"%F %T %z (%Z)"
1970-01-01 00:00:00 +0100 (BST)
This of course means that the --date argument to date is specified in
local time, not UTC. So when the hooks--update script does this:
date=$(date --date="1970-01-01 00:00:00 $ts seconds")
It's actually saying (in my timezone) "1970-01-01 01:00:00 UTC" + $ts.
Clearly this is wrong. The UNIX epoch started at midnight UTC not 1am
UTC.
This leads to the tagged time in hooks--update being shown as one hour
earlier than the true tagged time (in my timezone). The problem would
be worse for other timezones. For a +1300 timezone on 1970-01-01, the
tagged time would be 13 hours earlier. Oops.
The solution is to force the reference time to UTC, which is what this
patch does. In my timezone:
$ date --date="1970-01-01 00:00 +0000" +"%F %T %z (%Z)"
1970-01-01 01:00:00 +0100 (BST)
Much better.

This is the update hook we use in all our git-repos.
It has some improvements over the original version, namely:
* Don't send every commit since dawn of time when adding a new tag.
* When updating an annotated tag, just send the diffs since the last tag.
* Add diffstat output for 'normal' commits (top) and annotated tags (bottom).
* Block un-annotated tags in shared repos.
I'm a bit uncertain about that last one, but it demonstrates how to
disallow updates of a ref which we use, so I kept it.
Note that git-describe is needed for the "changes since last annotated tag"
thing to work.
