When editing files on slow network filesystems, nedit ofen pauses (due to stat() calls) - how to disable?

[h***@public.gmane.org]

Hi,

I understand it is a feature of nedit that it looks for changes in the
edited file every other second (by calling stat() on the file).

However, this causes annoying pauses when editing a file on a slow
network filesystem.

I've tried to disable the check un-selecting the
preferences->DefaultSettings->Warnings options, but that does not help.

Using "strace nedit somefile.txt" I can see the stat() calls are still done.

Is there a way to disable that behaviour (short of changing the source
code)?

Thanks in advance,

Lutz

I'm afraid the only option is to modify the source code.
[CheckForChangesToFile() - source/file.c]
Even if you disable the warnings, NEdit still uses stat() to monitor the
file attributes (e.g. to update the title when the file is made
read-only externally).

I have not looked into the code, but can't the checking be done in a
way that it doesn't 'tie up' nedit.

Ok, thanks for pointing me to the function I'll have to change :-)

Maybe the frequency of doing so could be made configurable in some
future release (if there is a future release ;-) - such a check
certainly wouldn't hurt even on a slow network file system when done
only every 5 minutes or alike.

I'm afraid that would require at least a separate process/thread and
non-blocking IPC, as there is no non-blocking alternative to the
stat-syscalls. Quite an effort in comparison to just allowing to
configure the interval.
