bug#18426: 24.3; imenu-auto-rescan-maxout not mentioned in manual

[Ethan Glasser-Camp]

1. Turn on imenu-auto-rescan in some buffers.

2. Start using imenu which mostly seems to work fine on files ~60kb in size,
but occasionally gets stale and takes you to a line that doesn't
correspond to what you selected.

3. Read and reread
https://www.gnu.org/software/emacs/manual/html_node/emacs/Imenu.html
which explains that imenu-auto-rescan controls the automatic rescanning,
so everything should be fine. Why isn't this workinG?

4. Eventually discover that there's a variable called
imenu-auto-rescan-maxout, which is set to 60000. Sigh sadly and
customize it.


Relatedly, I'm not sure how old the imenu-auto-rescan-maxout variable
is, but it seems to me like 60000 is pretty small in 2014. I bumped it
up to 150000 and behavior is still essentially instantaneous. I see some
people online have bumped it up to ~10MB. In addition to documenting the
variable, would it maybe be a good idea to raise it a bit?

bug#18426: 24.3; imenu-auto-rescan-maxout not mentioned in manual

I guess we could multiply it by 10.

bug#18426: [PATCH] Increase default size of imenu-auto-rescan-maxout

[Alex Branham]

[-- Attachment #1: Type: text/plain, Size: 1388 bytes --]

I just ran into this issue that was originally reported 4 years ago.
Here's a patch that increases the default size of
imenu-auto-rescan-maxout by a factor of 10 like Stefan suggested, though
honestly we could probably increase it past this even.

I also removed the doc about it being a buffer-local variable because
it's not AFAICT.

This doesn't need a NEWS entry, right?

Thanks,
Alex

bug#18426: [PATCH] Increase default size of imenu-auto-rescan-maxout

[Alex Branham]

Here's a patch that includes some text for the manual. I'm not sure of
the right way to submit this since the patch I send would go into 27.1
(I assume?), but this is a manual update that could go into the emacs-26
branch:

Thanks again,
Alex

You could probably put both of them in emacs-26, although thatʼs up to
Eli. In any case, emacs-26 gets merged to master regularly, so the doc
change could definitely go there.

Both changes would need commit logs in the format described in
CONTRIBUTE, and the increase in imenu-auto-rescan-maxout needs a NEWS
entry since itʼs user-visible.

Thanks for your efforts

Robert

Great, I've attached a patch that bunches it all together for the emacs-26 branch.

Thanks,

If this is intended for emacs-26, then this needs to say :version "26.2"

bug#18426: [PATCH] Increase default size of imenu-auto-rescan-maxout

[Alex Branham]

Any chance of getting this patch applied soonish so I can scratch it off
my todo list? Or have I missed some feedback/objection somewhere?

Thanks,
Alex

Pushed on Alex's behalf as 1c22f037fd to emacs-26

Alex, I wasn't sure if you'd signed copyright papers or not, so I
marked this change as exempt, since itʼs small. If youʼre planning to
contribute bigger changes to emacs, it would be good to get the
copyright assignment paperwork in order (I say 'paperwork', but the
process is pretty much electronic these days).

Thanks

He did.  In the future, I'd prefer that people asked about that
instead of assuming that copyright was not assigned.
