released dates

released dates

[Katsumi Yamaoka]

Hi,

I needed to download the Emacs 24.2 tarball after all to know
when it was released[1].  It has not been recorded even in the
24.3 tarball.  Is there a way by any chance to do it in a local
copy of the bzr repository?

Thanks.

I don't really know what you are asking; but the revision corresponding
to 24.2 is tagged "emacs-24.2".

You can use `-rtag:' in bzr:
  $ bzr log -rtag:emacs-24.2

Or see info-gnu-emacs[fn:1]

What I wanted to know then was whether a certain feature of Gnus
is in Emacs 24.x or not.  The date when the feature was added can
be found in the ChangeLog files, however it can't be known whether
it was done before or after the Emacs 24.x release; there is no
records in the normal files.  IIRC, there were all the ``released''
messages in the ChangeLog files.

Thanks.  It is helpful.

But, er, I realized what I really needs is not Emacs' release dates.
For example, the change made for `gnus-shr-put-image' is not in
Emacs 24.2 even if the ChangeLog in the trunk says as follows:

2012-02-01  Lars Ingebrigtsen  <larsi@gnus.org>
^^^^^^^^^^
 * gnus-art.el (gnus-shr-put-image): Take and pass on a `flags'

Thanks again.

What (I hope) you should do is use a graphical tool to visualize the
merge history.  (You can also use bzr log -n0.)  Find the branch where
this was added.

Of course if Gnus merges are done from a different VCS using patch
rather than a commit-syncing tool this won't work. :-(

You probably want to run "bzr annotate" on (in this case) gnus-art.el
in the Emacs repository, find the bzr revision where that change was
made, and then compare that revision with what "bzr log -rtag:" shows.

I tried "bzr annotate" for the first time.  I felt it will be more
useful than looking for a log message and a revno in the output of
"bzr log" (and then comparing revno-1..revno).  I have two local
copies of Emacs, emacs/trunk and emacs/emacs-24; I verified "bzr
annotate" done in emacs/emacs-24 shows helpful informations, too.

Thank you.

Or the vc-annotate command.  It creates an annotate buffer displaying
the file's text, with each line tagged with the revision number, which
has a `help-echo' property containing author and date information.  You
can browse the annotations of past revisions, view diffs or log entries.

See (info "(emacs) Old Revisions").
