nnfolder and large-file-warning-threshold

nnfolder and large-file-warning-threshold

[Reiner Steib]

Hi,

when using Gnus with the nnfolder[1] back end which is used by default
for sent messages, people get...

| File sent-mail is large (11MB), really open? (y or n) 

... when sending a mail.

This is caused by the variable `large-file-warning-threshold' that has
been introduced in Emacs 21.3.50.

Should we bind `large-file-warning-threshold' to a larger value (or
nil) in the relevant Gnus functions[2] or would it be better to
increase the default value of `large-file-warning-threshold'?

Bye, Reiner.

[1] The nnfolder back end is a "one file per group" back end.
    I.e. the file may grow quite fast when a user stores sent
    attachments there.

[2] `nnheader-find-file-noselect' (used in `nnfolder-read-folder',
    `nnmbox-read-mbox', `nnbabyl-read-mbox', ...)

No opinions on that?  Could someone explain the reason for
`large-file-warning-threshold'?

Emacs doesn't handle large files very well in my experience (particularly if
they're not read in as binary in fundamental mode), so I've added this
warning in case you open a very large file without intending to.

I guess the warning should not happen for files opened with
find-file-literally (presumably nnfolder doesn't just use
`find-file-noselect').

Do you mean that you find a bug on decoding a very large
file, or that the decoding is just very slow?

It's just very slow.

Just to make things clear: I do not know whether it's due to decoding.

I see.

I believe it's due to decoding (especially when decoding a
large utf-8 file).

I've committed the following change (to Gnus' CVS; trunk and v5-10):

	* nnfolder.el (nnfolder-read-folder): Use RAWFILE for
	`nnheader-find-file-noselect' to avoid
	`large-file-warning-threshold'.

Bye, Reiner.

This won't be a remedy for people using large nnfolder
archives/groups.  But I certainly would object to such a change.  I
don't know if it can be done in a backward compatible way.

Bye, Reiner.
