While we're at it, I wish 'git stash clear' would take an optional
argument that says which stash(es) to clear, rather than blindly clearing
the entire stash.

Short of that, there's always manually editing .git/logs/refs/stash, to
delete the lines to the stashes you no longer need, without killing the
ones you want kept.

making "git stash" safer to use

[Bruno Haible]

Hi,

Through a simple typo I lost modifications to 20 files:

> >>>     $ git stash
> >>>     $ git pull
> >>>     $ git stash apply
> >>>     $ git stash clean              # typo!
> >>>     $ git stash clear              # fatal correction to typo!

It is just too easy to lose your modifications by using "git stash".

Eric Blake further says:

It would help if git would store which of the stashes were applied since
they were created and which were not. A stash that was not yet applied must
be considered "precious", whereas a stash that was applied is redundant,
right?

According these lines, how about
  1) changing "git stash clear" to remove only the redundant stashes,
     (or alternatively: let it fail if there is at least one precious stash),
  2) adding an option -f, so that "git stash -f clear" clears all stashes,
     including the precious ones.

The rationale is that humans are bad at remembering the state of something.
Therefore instead of having a command that is commonly used in one state
and dangerous in the other state, better have two different commands - one
for the common case, and one for the dangerous one. Like "rm" and "rm -f".

Wrong.  I would say all stash entries are precious unless you
explicitly say "I'm done with it".  The problem is that we do
not have a way to say it explicitly.

What makes it most dangerous is that there is no differentiation
between a name and a command in the same position. I'd argue that 
either the command should be mandatory:

git stash save mywork
git stash apply mywork
git stash clear mywork
git stash mywork       # error

(we can still keep today's shortcuts "git stash" and "git stash apply", 
but only for the un-named case),

or that the command should be of the option type:

git stash mywork
git stash --apply mywork
git stash --clear mywork


-j.

Hear, hear!  I vote for the latter.  The former is still better than
the current state, though.

I finally found some time to hack something and here is my git-merge- 
changelog Perl script.  I tested it quickly and it seems to work  
fine.  It will mess up the ChangeLog entries when a commit actually  
modifies an existing ChangeLog entry.  It needs more testing but I'm  
just throwing this out in the wild for people that have interest in  
this to review.  I will eventually come up with a solution for the  
commits modifying existing entries and a testsuite.

I'm CC-ing the Git ML just in case it interests some more people over  
there.

In order to use it, add the following to your ~/.gitconfig:
[merge "cl-merge"]
         name = GNU-style ChangeLog merge driver
         driver = /path/to/git-merge-changelog %O %A %B
(you can also add it to a specific working copy by adding it in .git/ 
config instead)

Then, in the directory where the ChangeLog is, add a .gitattributes  
file with the following content:
ChangeLog       merge=cl-merge

For more information, see man gitattributes.

Let me know if something goes wrong.

Two comments:

  will not do it.

- Try to avoid naming the script git-merge-*; these scripts/programs are 
  merge _strategies_, not merge _drivers_ (and yes, we already have two

Re: git: avoiding merges, rebasing

[Bruno Haible]

[-- Attachment #1: Type: text/plain, Size: 2146 bytes --]

Hello Benoit,

Thanks for working on this. But this merge driver has a few major nits.


1) While my ChangeLog file was locally unmodified but some pulled in commits
   should modify it, "git pull" stopped and said:

ChangeLog: needs update
fatal: Entry 'ChangeLog' not uptodate. Cannot merge.

[I cannot swear on this, because I did not do a "git status" before the
"git pull", but this is in a directory where I usually have no pending diffs.]

The ChangeLog in question is the one from gnulib
(git clone git://git.sv.gnu.org/gnulib).


2) This "merge driver" did much more than sorting in a merge: it sorted the
entire file! In doing so,
  - It changed the order of ChangeLog entries in a way that does not represent
    the historical commit order.
  - For ChangeLog entries with multiple contributors, it shuffled around these
    extra contributors to other ChangeLog entries.
  - Near the end of the file, it made a change that I cannot explain.

Find attached a context diff of all the bad changes that it did.


In my opinion, a merge driver should not do changes to the file except
in the range of lines where the conflict occurred. For a ChangeLog driver,
all uncommitted entries should be collected at the top of the file, because
1. ChangeLogs are kept in the order of historical commit in the central
   repository,
2. other developers always look at the top of the ChangeLog; if a ChangeLog
   entries is inserted second or third after some already present entries,
   the danger is too high that the change gets unnoticed.

So "git-merge-changelog OLD CURRENT OTHERS" should IMO do the following:
1) Collect the changes between OLD and HEAD (I don't know if that is CURRENT
   or OTHERS?), in two categories:
     - added entries,
     - changed and removed entries.
2) Back out the added entries, keeping only the changed and removed entries
   as modifications.
3) Do a normal merge between this and the pulled in remote branch (I don't
   know if that is OTHERS or CURRENT?). If that merge gives a conflict,
   bail out.
4) Insert the added entries at the top, in the same order as they were
   originally (no sorting).

Bruno

I'll check but I'm afraid that Git bails out before actually trying  
the merge driver.

Yes, it's pretty stupid, I hacked this in a hurry.  I'll try to  
improve it so that it doesn't have these undesired side-effects.

OK I'll try to rework the driver so that it implements this.  It will  
take some time though, I'm quite busy these days.
Akim Demaille would also like it to squash the commits added by the  
merge (the new commits in OTHERS):

YYYY-MM-DD  Author  <who@where.com>

	Merge whatever:

	YYYY-MM-DD  Someone Else  <foo@bar.com>
	Some change.
	* FileChanged.c: Whatever.

	YYYY-MM-DD  Who Cares  <who@cares.com>
	Some other change.
	* OtherFile.c: Do it.

I thought this was mandated by the GNU Coding Standards but I  
checked, it doesn't say anything about merges.  Would this sort of  
strategy be useful to you?  Should it be default (or enabled by some  
--squash option)?

This merge is occurring in a different situation:

The situation where we need ChangeLog merging most often is when a developer
has made changes on his own and pulls in the changes from the remote repository
(via "git stash; git pull; git stash apply").

The situation that Akim is describing is that he pulls changes from the
repository of Someone Else and Who Cares, and then pushes them into the
central repository, under his responsibility.

For the first situation, the non-remote ChangeLog entries should be moved
to the top, without modification or indentation.

For the second situation, three different styles are in use at GNU
(because they don't use "Signed-off" lines):

1) unmodified copying of the ChangeLog entries:

YYYY-MM-DD  Someone Else  <foo@bar.com>
	Some change.
	* FileChanged.c: Whatever.

YYYY-MM-DD  Who Cares  <who@cares.com>
	Some other change.
	* OtherFile.c: Do it.

2) copying with lieutenant's email address, like Akim described it:

YYYY-MM-DD  Lieu Tenant  <who@where.com>

	YYYY-MM-DD  Someone Else  <foo@bar.com>
	Some change.
	* FileChanged.c: Whatever.

	YYYY-MM-DD  Who Cares  <who@cares.com>
	Some other change.
	* OtherFile.c: Do it.

3) similar, but with indentation of the entire copied-in ChangeLog entries:

YYYY-MM-DD  Lieu Tenant  <who@where.com>

	YYYY-MM-DD  Someone Else  <foo@bar.com>
		Some change.
		* FileChanged.c: Whatever.

	YYYY-MM-DD  Who Cares  <who@cares.com>
		Some other change.
		* OtherFile.c: Do it.

First of all, your merge driver could try to guess whether we're in the
first or second situation (maybe by testing whether the names in the
ChangeLog entry match the [user]name from the git config).

Then, for the second situation, there can be some flag in the driver or in
the git config that describes which of the 3 styles to apply.

I'd rather avoid "enhancing" stash clear.  IMHO it is a little 
misdesigned, making it way too easy to hang yourself.

Instead, how about writing a stash pop?  "git stash pop [<stash>]".  It 
would literally just call git stash apply && git reflog delete.  Should 
not be too difficult, now that I provided "git reflog delete" ;-)

Maybe even deprecating "git stash clear", or doing away with it 
altogether.

That would match my usual usage well.

Actually, I really like the way the tla (arch) "undo" and "redo"
commands work:  "tla undo" is roughly equivalent to "git stash", but by
default chooses a name with an appended integer which is one greater
than the greatest existing "stash" (to use git terminology).  "tla redo"
by default applies the last saved value and deletes it.  So basically
push and pop.  Usually, of course, you only use one level, but on the
occasions when you want more, it feels very natural.

I dunno how this would work with stash, but push/pop functionality would
be good...
