StGit: kha/safe and kha/experimental updated

[Karl Hasselström]

Both branches updated. I've promoted some experimental patches to
safe, and done some work on new and delete (will post the patches in
reply to this mail).

[StGit PATCH 1/5] Disable patchlog test for "stg new"

[Karl Hasselström]

This will be broken by the "stg new" rewrite, so stop testing it.

Signed-off-by: Karl Hasselström <kha@treskal.com>

I'm doing this rather than fixing the log since I hope to actually
create "stg undo" pretty soon, and that'll involve a new internal log
format. But I won't graduate this to kha/safe until it's resolved
either way.

[StGit PATCH 2/5] Convert "stg new" to the new infrastructure

[Karl Hasselström]

This results in considerable code expansion, which is a sure sign that
something needs to be abstracted away -- but to keep things simple,
those transformations come as separate patches.

[StGit PATCH 3/5] Refactor --author/--committer options

[Karl Hasselström]

This refactoring is specific to the new infrastructure, so only new
and edit use it currently, but other commands can start using it as
they are converted.

While testing my editor searching ordering patch i found that
this patch(Refactor --author/--committer options) seems to break
"stg edit" (without arguments) starting a interactive editor for me.
When i issue "stg edit" it silently does nothing.

It seems the following comparison does not return True

># Let user edit the patch manually.

I can work around this by adding a comparison function to Commitdata
but maybe __eq__ or __ne__ should be used instead(prevent similar bugs caused
by == comparison)?
I would guess the initial cause for this is that the following line which unconditionally replaces cd.

So another way to fix this might be, to not overwrite cd unconditionally.

Thanks for the report. And yes, as far as I can tell your analysis is
spot on. In the initial patch I remember being careful to not replace
cd unless it was actually changed, but obviously I got sloppy after
that. :-(

Yes, you'd definitely want the common operators to work. But I usually
implement __cmp__ instead of __eq__ and __ne__ -- that gives you all
of <, <=, =, !=, >=, and > for the price of a single method. And it's
usually possible to define it rather simply in terms of cmp() with
tuple arguments, like this:

    def __cmp__(self, other):
        return cmp((self.__tree, self.__parents, self.__author,
                    self.__committer, self.__message),
                   (other.__tree, other.__parents, other.__author,
                    other.__committer, other.__message))

This sidesteps the great problem of cmp -- having to remember when to
return 1 and when to return -1.

Yes, this is what we want -- if the user gives --author, we shouldn't
open the interactive editor even if the given author is the same as
the patch already had.

Updated patch on the way.

[StGit PATCH] Refactor --author/--committer options

[Karl Hasselström]

This refactoring is specific to the new infrastructure, so only new
and edit use it currently, but other commands can start using it as
they are converted.

And here it is. The relevant piece of code now reads

    a, c = options.author(cd.author), options.committer(cd.committer)
    if (a, c) != (cd.author, cd.committer):
        cd = cd.set_author(a).set_committer(c)

This works because the default value for options.author and
options.committer -- used when no commandline options are given -- is
the identity function.

[StGit PATCH 1/2] Convert "stg delete" to the new infrastructure

[Karl Hasselström]

In the process, it gains the ability to delete any applied patch (not
just the topmost one, like before), even when deleting patches from
another branch. (However, when deleting patches on another branch, we
obviously can't represent a conflict in the index and worktree, so any
conflicts will make the operation abort.)

One of the t1600 subtests made sure that we couldn't delete
non-topmost patches, and had to be corrected.

Signed-off-by: Karl Hasselström <kha@treskal.com>

Unlike the "stg new" conversion, this resulted in a sizeable reduction
of lines of code, and of code complexity.

David, could you have a look at this as well? In addition to me being
elisp challenged, there are the following issues:

  * Is "d" a reasonable binding? Any better suggestion?

  * Currently, this command requires you to mark one or more patches
    before deleting. This is convenient when deleting more than one
    patch, but one could argue that it should be possible to delete
    the patch at point without having to select it.

  * We should probably ask for confirmation before deleting.

We could reserve "d" for moving a patch "down", maybe.  The more
destructive commands could be on less accessible keys. Maybe "D" or

I'll take "D" then, since control bindings are more likely to collide
with existing bindings (as is already the case with C-r for stg
repair).

True, maybe we should move the repair binding as well.

Teach the emacs mode to delete patches. It will delete the selected
patches, or, if no patches are selected, the patch at point (and if
there is no patch at point, complain). Before deleting, it will ask
for confirmation.

Thanks, I merged them last night. I now have to spend some time to
understand StGIT as it's moving too fast :-). I'll try to put back
some of the things I use like the automatic invocation of the merge
tool during conflicts etc.

StGit: kha/safe and kha/experimental updated

[Karl Hasselström]

kha/safe contains two patches that were posted to the list quite some
time ago. Sorry for the delay! kha/experimental still has the
new/delete rewrites from way back when, plus a new and shiny "stg
reset" prototype!

It works like this:

  1. Every StGit command that modifies anything writes the new state
     to a log. The log is a git branch called <branchname>.stgit.

  2. When you've done something you regret, find the state in the log
     you want to return to and just say (for example)

       $ stg reset master.stgit~3

     Resetting is recorded in the log just like everything else, so to
     undo a reset you just did, simply say

       $ stg reset master.stgit^

There are lots of things that have to be ironed out before it's done,
especially the UI, but it's ready for folks to play with and comment
on.

That's cool :-), thanks. We can even add aliases for 'undo' and 'redo'.

It's not entirely clear (to me at least) exactly what undo and redo
should do. Something like this maybe:

  undo: If the log begins with k "undo" entries (k >= 0), reset to
        log~(2k+1).

  redo: Find the most recent "undo" entry that hasn't been cancelled
        out by a "redo". If this is the most recent log entry (except
        the cancelled-out ones), reset to it; otherwise, complain that
        the last command was not an undo or redo.

I _think_ this does what one naively expects undo and redo to do.

Yes, something like this. Anyway, this can be explained in the help
without adding separate commands (at least for now).
