Regex error in most recent update

Hi everyone,

I just noticed we had two email servers complain last night after
running sa-update about a regex problem:
/etc/cron.daily/spamassassin:
config: invalid regexp for __URI_TRY_3LD
'm,^https?://(?:try(?!r\.codeschool)|start|get(?!\.adobe)|save|check(?!out)|act|compare|join|learn(?!ing)|request|visit(?!or|\.vermont)|my(?!sub|turbotax|news\.apple|a\.godaddy|account|support|build|blob)\w)[^.]*\.[^/]+\.(?<!list-manage\.)(?:com|net)\b,i':
Variable length lookbehind is experimental in regex; marked by <-- HERE
in
m/(?i)^https?://(?:try(?!r\.codeschool)|start|get(?!\.adobe)|save|check(?!out)|act|compare|join|learn(?!ing)|request|visit(?!or|\.vermont)|my(?!sub|turbotax|news\.apple|a\.godaddy|account|support|build|blob)\w)[^.]*\.[^/]+\.(?<!list-manage\.)(?:com|net)\b
<-- HERE /

channel 'updates.spamassassin.org': lint check of update failed, channel
failed
sa-update failed for unknown reasons


Did anyone else notice the same thing or is it just on our end?

Kind regards,
Bert

same issue here with Spamassassin from Debian Buster and Bullseye.

Wow, this one is pretty subtle. It is due to:

Or vice-versa - in this case "ss"/"st" collapses to "ß"...

...and it's not universal, either. It passed lint here or I wouldn't have
checked it in. It passed the masscheck lint or it wouldn't have been
published.

I've checked in a fix, there may be one more bad update tonight before it
goes out.

Can confirm, too. Just saw this from yesterday's daily cron output:

/etc/cron.daily/spamassassin:
config: invalid regexp for __URI_TRY_3LD
'm,^https?://(?:try(?!r\.codeschool)|start|get(?!\.adobe)|save|check(?!out)|act|compare|join|learn(?!ing)|request|visit(?!or|\.vermont)|my(?!sub|turbotax|news\.apple|a\.godaddy|account|support|build|blob)\w)[^.]*\.[^/]+\.(?<!list-manage\.)(?:com|net)\b,i':
Variable length lookbehind not implemented in regex
m/(?i)^https?://(?:try(?!r\.codeschool)|start|get(?!\.adobe)|save|check(?!out)|act|compare|join|learn(?!ing)|request|vi.../
channel: lint check of update failed, channel failed
sa-update failed for unknown reasons

https://bz.apache.org/SpamAssassin/show_bug.cgi?id=7956 was meanwhile
fixed.
Today's cron output didn't show the error anymore.
Thanks to all involved for reporting and fixing!
