Subject: 23.0.91; vc-next-action in vc-dir acts strangely when only adds are necessary
Date: Sun, 15 Mar 2009 15:06:56 +0900

[Note: I have Dan's patch for fixing whole-directory vc-dir commit in
Git applied, though I don't think it should affect the following, as it
relates to final commit.]

If I have a vc-dir buffer showing a tree where the only entries are new
files (not yet registered with source-control):

   VC backend : Git
   Working dir: /tmp/zonk/
   Branch     : master

                            ./
        unregistered        llll
        unregistered        oiuoiu

Then hitting "v" on the first line of the buffer acts strangely -- I'd
expect it to simply register all these files with source control, but in
fact, it simply appears to do nothing.

There are actually several behaviors (though it always does nothing in
the end).  If this is the first time I've tried to do this, it just
displays a message like "Registering (/tmp/zonk/)... done" [where
"/tmp/zonk2" is the root of the working directory in question] but
doesn't seem to really do it.

If I then try the "v" command again, it will first show the message:

   Previous master file has vanished.  Make a new one? (y or n) 

If I enter "n" it just gives an error and aborts.

If I type "y", then it will either display a "Registering
(/tmp/zonk/)... done" message like the initial time (and again have no
real result), or show a *vc-log* buffer to prompt for an "initial
comment"; in the latter case, when I then hit C-c C-c to continue, the
*vc-log* buffer goes away -- but nothing further appears to happen.
[I'm not sure what causes it to open a *vc-log* buffer or not ... in my
initial tests it did, but when I tried again with emacs -Q, it didn't.]

Anyway, the end result is always the same, no registered files.


To reproduce:

  (1) Execute the following shell script to create a test repo in
      "/tmp/zonk2":

#!/bin/sh
cd /tmp
rm -rf zonk2
mkdir zonk2
cd zonk2
git init
echo plugh > ppling
git add .
git commit -m'Init' -a
echo Fnord >> newf1
echo Chnevy >> newf2

  (2) Start emacs:  HOME=/tmp emacs -Q -nw

  (3) Start vc-dir on the test repo:  C-x v d /tmp/zonk2 RET

  (4) Without moving the cursor, try to register the new files:  v
  
  (5) It will exhibit one of the faulty behaviors described above,
      resulting in no file registration being done.

Thanks,

-Miles

This is a vc-git.el problem, vc-git-register does not register the files.
Try the same thing with, say, mercurial and it work.

Given that you are familiar with git, the function to fix to get this
working is the one liner `vc-git-register':

(defun vc-git-register (files &optional rev comment)
  "Register FILE into the git version-control system."
  (vc-git-command nil 0 files "update-index" "--add" "--"))


just add the correct command(s) to run to vc-git-command, and it should
work.

In case above vc-git-register is called like this:

(vc-git-register "/tmp/zonk2/")

The obvious solution is to use "add" instead of "update-index --add".

[I tested it, it works.]

However, it'd be nice to ask whoever wrote this function originally
whether there was a reason for using "update-index" instead of "add",
given that vc.el apparently expects higher-level level functionality
(recursion) from the register hook.  I suppose update-index is the
more conservative choice, since it's officially "plumbing", but I'm
not aware of any problems with using the higher-level git-add in this
case.  [The git backend already uses "add" in other places too.]

Also, I wonder:

  (1) Given that vc-dir already has a list of files presented in the
directory listing, how come it doesn't give the backend that list,
instead of just the directory (having the backend do the recursion
seems more likely to yield unexpected results)?

   (2) Perhaps vc-dir it should do a "revert-buffer" (or something)
afterwards when it operations on a subdirectory or the whole
directory, as any operation with the backend doing the recursion may
change something other than what is displayed.  This is easy to see if
their were unregistered subdirectories with files -- doing "v" to
register a subdirectory adds all files in that directory, which vc-dir
hadn't displayed before, so currently "v" doesn't properly show them
afterwards (doing "g" shows them).

I'd assume it would be the vc-git.el author.

When the point is on the "./" entry (or before), and nothing is selected
it means that you are asking for an action to be performed on the
directory, that is gets sent to the VC command.
If you want a list of files to be sent, mark a list of files and that is
what will be sent.

It does, but there might be other things not working correctly with git,
try with hg and you will see it working correctly.

It does what?  A revert?  Or always updates the display correctly in
the subdir case without a revert?  If it's the latter, what mechanism
does the backend use to communicate to vc-dir that more stuff has
shown up?  [or does the backend just do a revert itself?]

Thanks,

vc-register creates a call to vc-start-logentry
vc-start-logentry calls vc-finish-logentry which calls vc-resynch-buffer
vc-resynch-buffer updates both the buffers that might have been
affected by the VC command and the vc-dir display (this one via the 
vc-dir-resynch-file call).

Oh, incidentally -- that's another problem with the vc register stuff,
it prompts for a log message, which is useless for git (is it useful
for any non-cvs system?).  Is there a way for the backend to suppress
that behavior?

Thanks,

Probably not...

I've never seen this happen, so I don't know of the top of my head how
to avoid it.  Can you describe what you do so that I can reproduce it?

Hmm, actually it seems to be my configuration -- I have
`vc-initial-comment' customized to `t'.

Perhaps it should be ignored for backends where it's pointless, but
for now I'll just change my configuration ... :-)

BTW, this trip via vc-start-logentry should be removed.  It's a remnant
from old times when vc-register had an opportunity to provide a message
linked to the file's addition, but nowadays it's just extra baggage that
makes the code less readable.
