How to delete caches

How to delete caches

[Johannes Altmanninger]

I've been using lei from the 1.7.0 release, which works great.

I had some unrelated problems with one of the created maildirs so I deleted
said maildir.  Now I can't recreate the maildir. I tried deleting all
persistent data but got an error:

	$ rm -rf the-maildir ~/.local/share/lei ~/.cache/{public-inbox,lei}
	$ lei q -I https://lore.kernel.org/git/ -o the-maildir rt:1.week.ago..
	failed to open /home/johannes/.cache/lei/all_locals_ever.git/lei_ale.state: No such file or directory
	 at /usr/share/perl5/vendor_perl/PublicInbox/LeiQuery.pm line 117.

A quick look at strace doesn't show access to any other files in $HOME

lei q error after deleting cache (can't find mail_sync.sqlite3)

This is pretty weird: it works in a temporary home, but only for the first time.

	rm -rf the-maildir someuniquename; HOME=$PWD/someuniquename lei q -I https://public-inbox.org/meta/ -o the-maildir rt:1.day.ago..

When I re-run this command, I get the same error
There seems to be no mention of someuniquename anywhere on my disk (except
in my shell history).

Have you tried killing the daemon (`lei daemon-kill')?

Thanks, that fixed it. I wasn't aware that there is a daemon

Yeah, these are holes in our inotify coverage.  We use inotify
(and kevent) to monitor some things (Maildirs, sockets, ...),
but there are some missing pieces, as you've noticed :<

Will try to get around to fixing these at some point...
