[PATCH 0/6] cli: support regex in new.ignore

[PATCH 0/6] cli: support regex in new.ignore

[Jani Nikula]

I dusted off some of my old patches to add support for /regex/ in
new.ignore. Regex instead of globbing because we now have prefix
searches with regex, so this is perhaps more in line. Some cleanups for
starters.

BR,
Jani.

[PATCH 5/6] cli/new: support /<regex>/ in new.ignore

[Jani Nikula]

Add support for using /<regex>/ style regular expressions in
new.ignore, mixed with the old style verbatim file and directory
basenames. The regex is matched against the relative path from the
database path.

Is it worth remarking that '/' does not need to be escaped? or more
interestingly, what happens if it is escaped, do things break?

One thing we eventually settled on in the query parser is that an
opening '/' without a trailing '/' is an errror. But perhaps it's fine
to take a more permissive approach here.

It's a nitpick, even by the standards of this review, but I'd prefer an
explicit '> 0' check.

It just gets passed down to regcomp() with the escape and all. I'm not
sure it's worth trying to exhaustively explain everything.

Something like:

/* Jani forgot to do anything useful with the return value */

I think it was originally meant to return false on illegal input
(e.g. opening '/' without closing '/') or regcomp() failing, but then I
opted for the more lax approach. xregcomp() warns about failures though.

I'm fine either way, I just chose to be permissive.

So do I make the function void and drop the return values, or make it
check and return errors?

ITYM (state->ignore_regex_length == 0) but ack.

I think I'd prefer to start strict, it's easier to become permissive later.
