Hi,
I've noticed that sometimes project-kill-buffers is noticeably slow, and
it seems like it's has to do with project--buffer-list working on remote
files. The function goes through every buffer and calls
(project-current), even if the buffer is related to a remote file that
cannot be part of the current project.
The patch I attach below is a simple fix to avoid checking files that
cannot be part of the current project. Or are there any edge-cases that
this code approach breaks?

How 'bout using `file-in-directory-p`?

I didn't know about that function! Just tried it out and it seems that
the patch below is even faster, as project-current does not have to be
invoked for every buffer, remote or not.

I think it might misbehave if you have projects nested in the directory
of other projects, tho.

That is true, but this leads to the more general question of whether a
sub-project is part of the super-project or not? Is there any reason to
intrinsically prefer one over the other?

If sub-project is part of the super-project, what makes it a separate
project, then? If we do consider it separate, I think it makes sense to
only kill buffers belonging to it, but not the parent. And vice versa.
Ultimately, it's a non-trivial question, and we'll probably delegate it
to project backends as well. That will still require getting the current
project.
We also want to support arbitrary project-finding strategies which
dosn't depend on the parent directory (see commit 4ca13d98c9eb and the
referenced discussion).

In theory, files on different hosts could be part of the same "project"
(in Eli's sense, see
https://lists.gnu.org/archive/html/emacs-devel/2020-07/msg00051.html and
the other messages in that thread), but we'll get there when we get
there. Probably by adding a method like project-contains-file-p.
In the meantime (until somebody complains), the patch like this should
be fine. I haven't found any significant difference in performance, but
I don't have Tramp buffers in the current session.
Pushed to master, thanks.
If we do believe that a project can only span one host, we could also
change the check like this:

Of course, we could also make the check super fast by keeping the
"current project" in a buffer-local var, and then just look for buffers
which have an `eq` value in that var. That would be both faster than
`file-in-directory-p` and more arguably more correct.

Until the user changes some project setting and the "current project"
becomes not current anymore.

All that looks to me like a classical caching problem, with cache
invalidation protocols and things.
(Don't take me too seriously, though. I've no skin in this game).

Sure. I'm just not in a hurry to add the cache if it limits possible
applications, since the current performance seems adequate most of the time.
Better explore the applications first.

There are also projects that do not have a single root; an Emacs elisp
project (which has load-path as roots), any project with dependent
external libraries.
You can check (member file (project-files prj)), but that's about the
same as your first patch.

So maybe something like
(let ((root (project-root proj))
(extr (project-external-roots proj)))
(member file (project-files proj (cons root extr))))
?

I realize that one issue here is that external roots could be shared by
multiple projects, so you wouldn't want to kill them when cleaning up
after a project even if you would want to have them listed.

I don't think you'll like the performance characteristics of this
approach. ;-)

This is not really than different.
The VC backend has load-path in external roots (which can have
counterparts in "dependency libraries" in other languages).
When we close such project, though, we usually don't want to kill any of
the buffers belonging to external libraries (they might as well be part
of some other project, e.g. one that the current depends on).
To support arbitrarily-shaped projects, though, we can introduce a
method like 'project-contains-buffer?'. Which you would implement with
'member'. The performance could be okay if your projects are small
enough. It doesn't handle non-file-visiting buffers, though.

Which means you need to provide an option for the times when we want the
other behavior: C-u kills root and external-roots, plain kills root only.

I wouldn't mind adding an option, but that presents a difficulty.
At the moment, we call `project-current` in each buffer and compare the
returned value to the "current" project instance. That wouldn't work for
external roots no matter what option we add because a given file inside
"external root" can belong (in an "extended" sense) to several projects
at once, so there's no logical way to obtain the project instance we're
looking for based on such external file. Right?
A generic like project-contains? I previously mentioned would have a
problem that every project backend's implementation would have to obey
such an option, which creates new possibility for bugs and diverging
behaviors.
If the current project-kill-buffers doesn't work for you (please check;
IIRC your backend's peculiar behavior might have an upside in this
case), what we could more easily do is create an option like
'project-list-buffers-function'. The default would delegate to
project-current. The alternative could indeed use file-in-directory-p
(or a string comparison to similar effect) as discussed in this thread,
providing a different inclusion semantics and improved performance, and
the third alternative value could enable looking in external roots as well.

There is in my projects; the currently active global project. Which
means that any buffer will appear to "belong" to that project, unless
project-find-functions is buffer-local, as it is in my elisp buffers.
I view project-current as returning an object useful for project-related
commands. So in a "notes" text file, where I keep track of things to do
for a project, I want project-find-file to use that project (which is
the current globally selected project). project-delete-buffers should
delete that notes file. But in a higher level notes file, opened on
Emacs start, that lists all the projects I'm currently working on,
project-find-file should also use the current global project, but that
buffer should not be deleted with the project.
> A generic like project-contains?
That's one option, with the current predicate in project--buffer-list as
the default implementation; then I could override that to check
project-files, or all roots, or something. As long as it passes C-u to
the backend, my function could also use that to decide about dependent
libraries.
It might be better to make the predicate more specific;
project-delete-this-buffer-p. That way eglot won't try to abuse
project-contains to pick a server :). Or maybe my delete buffer case
and eglot's "choose the right server" case really are the same?

Yes. Things should be as simple as possible, but no simpler.
A default that is useful in many simple projects helps a lot.

First, M-x project-kill-buffers dies because my definition of
project-root returns nil. I suppose you'd call that a bug in my project
backend, so I'll pick some arbitrary directory (essentially (car
compilation-search-path)) and call it the "primary root".
Then the prompt is:
Kill 17 buffers in d:/apps/gnat-gpl_2020/lib/gnat? (yes or no)
That directory is something you would call an external root, I guess, so
you would argue I should pick a different one. But I have lived with
project-root returning nil for several years now, so I don't see why I
should be forced to put effort into choosing some "better" root, just so
project-kill-buffers can detect a remote project. I'd be happy if that
remote project predicate treated nil as "not remote".
In any case, 17 buffers is far too many; there are only three buffers
open related to the current project. (length (buffer-list)) is 24, so at
least it's not deleting everything.
Hmm. I just found project-kill-buffer-conditions; maybe I could
customize that; it allows arbitrary predicate functions. It would be
more efficient if the predicate function were also passed the project
object, so it doesn't have to call project-current again (hmm - shades
of project-delete-this-buffer-p :).
A better prompt would be the name of the project; the ELPA package wisi
defines a name for each project, specified by the user as part of the
project definition. In this case, it is "ada_mode_wisi_parse stephe_6",
which is much more meaningfull to me, and more meaningfull than some
"better" "primary root" directory. In fact, I have two different
projects that share the directory of test files (one for compiling the
parser, one for running the parser tests), so a directory name does not
uniquely identify a project. Similarly, there are elisp and Ada files in
the ada-mode source directory; the elisp files use the elisp project
(named "elisp"), the Ada (and all other) files use the
"ada_mode_wisi_parse stephe_6" project.
I think another generic project-name, or possbly project-prompt, would
be good here. The default could be project-root.
There should also be a custom boolean to turn off the prompt; it's
helpful the first few times, then it's just annoying. Currently C-u is
'no-confirm'; I hope that will change to 'no-dependencies'. Normal Emacs
style uses a custom variable for suppressing prompts.
Even better would to define the key ? at that prompt to put up a list of
the buffer names; that way the user could learn to trust the command (I
certainly don't trust it now :). I suspect that would be very hard to do
(certainly yes-or-no-p can't do that now). Instead, the custom variable
that turns off the prompt could be tri-valued; nil (no prompt), t (short
prompt), 'verbose (list all buffers, with a hint on how to change the
prompt behavior). Then 'verbose should be the default. dired has similar
behavior when deleting one vs several files.
> what we could more easily do is create an option like

I don't see how that is better/easier than a cl-defgeneric; either way
the project has to specify the correct function, possibly on a
per-project basis. Either way you have to provide a useful default
implementation. And they provide the same power to encounter/create
bugs; they are both dispatching methods. I think it's better to stick to
one method of dispatching. In my case, the wisi package will provide the
function.
On the other hand, it appears we already have dispatching via
project-kill-buffer-conditions; I'll see if I can make that work. I'm
not sure I can reliably detect C-u from there for dependent libraries.
I already have a function similar to 'project-kill-buffers', defined in
my vc package; it kills buffers whose files are under a root directory.
That solves the question of whether to delete buffers in dependent
libraries, at the expense of requiring the user to invoke it several
times in order to fully clean up. So a correct solution for
project-kill-buffers, with a simple invocation-time option for dependent
libraries, would be nice.

This works for wisi projects, but not for the elisp project (it signals
an error):
(defun wisi-prj-kill-buffer-condition (buffer)
"Return non-nil if BUFFER should be killed.
For `project-kill-buffer-conditions'."
(let* ((source-path (wisi-prj-source-path (project-current)))
(buf-file-name (buffer-file-name buffer))
(done (not (buffer-file-name buffer)))
(result nil)
dir)
(while (and source-path
(not done))
(setq dir (pop source-path))
(when (and dir
(file-in-directory-p buf-file-name dir))
(setq done t)
(setq result t)))
result))
(setq project-kill-buffer-conditions
(list #'wisi-prj-kill-buffer-condition))
I'm not clear how to set project-kill-buffer-conditions on a
per-project basis; it would be simple if this was a cl-defgeneric
dispatching on the project.

Oh. Right. So simply comparing project-current won't work for "global"
projects like in your setup.

I'm fairly sure you don't want to close the buffers visiting the
dependencies. Or if we do, that would be a globally acting modifier, and
that piece of logic which we would add to project-kill-buffers would
just see whether the buffer's default-directory is inside any of the
"external roots", as defined by the backend. Would that work for you?

I'd rather we try to be more strict with semantics, if possible, and
'project-contains?' would only return t for buffers "inside" the
project, not stuff that's outside but related to it (like external
libraries, system includes, etc, which is what I'd like "external roots"
to be targeted at).

It also helps when we can encourage projects not to forget to obey the
option, some way or other.

Even if your project is "amorphous" in shape, I wouldn't necessarily
want to call its directories "external roots".
For project-root, though, you might pick something like the directory
that hosts the main configuration/build file.
That wouldn't help with the project-list-buffers-function approach, but
I suppose that just wasn't a great idea.

Yes, it's an interesting idea: if all buffers point to the current
project, you could do post-filtering in this var.

We can add that, but please file that as a separate bug report.

It *might* change to "include dependencies", since currently it's not
supposed to include them.
If you want this change to happen, could you outline the cases when you
would and would not use this capability? Personally, I'd probably never
kill those buffers.

I'd be happy to review a patch. If there are many such buffers, some
smart formatting of the list would need to be used, though.

Consider also this: you suggested a generic like
project-delete-this-buffer-p.
If in the end the set of buffers that project-switch-to-buffer uses, and
the one that project-kill-buffer uses, are very different, perhaps there
is not much benefit in having both of them do this through the project
API. Because the point of doing that is to be able to reuse the same
information in different contexts.
Like, if your backend would have to implement a method that's 5x as long
as the current project-kill-buffers definition, you might as well
provide an ada-project-kill-buffers command, right?
Just thinking aloud here.

I suppose if you set project-find-functions to a local value in

On the face of it, project-kill-buffer-conditions could use a PROJECT
argument to improve efficiency, but if you have a var which points to
the global project, your 'project-current' probably works very quickly.
So there wouldn't be much actual speedup in your case.
You can prove me wrong with (benchmark 1 '...) or (benchmark-progn ...).

Sometimes I do; I'm done working on ada-mode, and I transition to
working on my music database, closing all ada-mode related files. Other
times I don't; I found a bug in ada-mode, so I move to the wisitoken
library to run tests there, closing only the higher-level ada-mode
files.
The point is that it is up to the user, to decide on a case by case
basis.

I don't follow. What is the UI? How does the information given by the
user get passed to the backend? Only the backend can interpret
"dependencies".
And no, not all project files can be distinguished by directory; I have
files in the same directory that are managed by different projects (Ada
and elisp).

Then you need an "include-external-roots" arg to project-contains, since
sometimes that's what the user wants.

I gave examples above. In general, if I'm switching to a project that
shares some files with the current one, I don't want to delete those
buffers. So the correct semantics would be "switching from project A to
project B; close all non-shared buffers".

Hi Stephen,
I've posted a patch to
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=49264#38 which should add
the necessary flexibility, for your project backend to be able to list
its buffers without being tied to the root dir.
So far it just adds a generic called 'project-buffers'.

If the distinction is indeed useful, maybe the change mentioned above
can be followed with generic 'project-externals-buffers'.
Either way, it seems you might prefer a new command like
'project-kill-other-buffers' (as opposed to 'project-kill-buffers'),
which would kill all buffers (which satisfy
project-kill-buffer-conditions, of course) that don't belong to the
current project.

Yeah, scratch that.

For now it's project-buffers and (potentially)
project-externals-buffers, for nicer naming and being able to implement
in the vc backend in a performant fashion more easily (having predicate
methods would require caching some information in the project instance
between the calls).
But project-contains-buffer-p and project-externals-contain-buffer-p are
still on the table, if anybody feels strongly about that choice.

Sounds like 'project-kill-other-buffers' I described above. You might
not even need to make a distinction between project contents and
"externals" for this scenario (having 'project-buffers' return all
pertinent buffers).
But there can be other scenarios, I guess.
