Subject: 25.0.92; Cannot input 'Y' with dired-do-query-replace-regexp
Date: Wed, 13 Apr 2016 22:49:42 +0200

I cannot get dired-do-query-replace-regexp to replace all remaining
matches in all remaining buffers. To reproduce:

    $ for f in bar baz; do echo foo > $f; done
    $ emacs -Q .                                # works with -nw as well

    m m                 (mark bar and baz)
    Q oo RET aa RET     (replace "foo" with "faa")
    Y

At this point, with Emacs 24-5, 'Y' would, as the help suggests,
"replace all remaining matches in all remaining buffers with no more
questions".

With Emacs 25, 'Y' replaces one match in file bar, then leaves point
after "faa". File baz is left untouched.

There is also an *xref* buffer that pops up, with which I cannot do
anything:

- inputting 'g' yields "revert-buffer--default: Buffer does not seem to
  be associated with any file";
- inputting 'r oo RET aa RET' yields "user-error: Search results out of
  date".

If there is anything I can add to help reproduce and/or debug, please
let me know.

Thank you for your time!

I wrote dired-do-query-replace-regexp in the title, where I obviously
meant dired-do-find-regexp-and-replace. The former was the name of the
Dired function bound to Q in Emacs 24-5 (which works fine); the latter
is the name of the same function in Emacs 25 (where I experience the
bug).

Sorry for the confusion.

This should be fixed now in emacs-25 with commit 
922c7a3e48e649ad67bd12b1f83343b730dd1bc4. Thanks again for the report.

I've changed this to simply use `message' for now. The query-replace 
will skip over outdated xrefs and offer to replace the up-to-date ones.

We've previously discussed visualizing and automatically skipping the 
ones you've already answered the question about, but I'm not 100% sure 
yet which approach to use, so it's probably out of scope for 25.1.

Eli, should we consider this complaint a 25.1 blocker as well? It should 
be reasonably easy to resolve/implement.

I'm not sure.  For starters, I don't think I understand how is this
related to the original problem, of getting the correct behavior after
typing "Y".

If it isn't related, then what exactly is the problem with 'g' in the
XREF buffer that would need to be solved for Emacs 25.1?

Thanks.

It's tangential.

That it doesn't do anything? :)

Which limits the usefulness of showing the xref buffer when doing 
dired-do-find-regexp-and-replace, somewhat.

So you want to bind 'g' to a command that recomputes the xref buffer
to show only the remaining matches?  If so, I don't think we must have
it on emacs-25, unless 'g' does already do similar things in other
commands that present an xref buffer.

No, to repeat the search, so that the results are up to date. If the 
user answered `y' to all replacement prompts, then yes, the new results 
will only include the remaining matches. Otherwise, they will also 
include the skipped ones.

I could be handy to refresh the search results buffer after finishing 
with replacements, just to get an overview of the ones the user skipped, 
to make sure they didn't miss anything important.

It will be a solution for all xref buffers, touching more or less all 
commands that show them.

All right, not in emacs-25, then.

Perhaps implemented with a local binding of revert-buffer-function ?
This would give a natural meaning to revert-buffer in xref buffers.

Thanks! I cloned the repository, checked emacs-25 out and compiled:
dired-do-find-regexp-and-replace now behaves just like
dired-do-query-replace-regexp, so the issue seems resolved!

To be very nitpicky, I still notice one difference (other than the xref
buffer popping up):

When dired-do-query-replace-regexp finishes, it prints "All files
processed" in the minibuffer. Looking at the *Messages* buffer, I see
that before that, it actually printed "Replaced n occurrence(s)" for
every file it visited.

dired-do-find-regexp-and-replace does not print "All files processed",
so all the user sees in the minibuffer is "Replaced n occurrence(s)",
where n is the number of matches in the last processed file.

It is pretty minor of course, although for a second it did make me doubt
whether all files had been processed.


My observations on the xref buffer were indeed unrelated to the problem.
I was just trying to showcase everything I could think of to work around
the bug, and hopefully, provide more symptoms to ease debugging.

Thanks for the feedback, I've added a similar message.
