Length restriction of substitution string is too short

[gskinner]

Can you please provide a use case for a long substitution string? What would be a more appropriate max length for you? 200 chars? 1000 chars?

[sparkyfen]

1000 please.
Here is one that I am messing with:

(^access-list\s(.*)\sextended\s(permit|deny)\s(ah|eigrp|esp|gre|icmp|icmp6|igmp|igrp|ip|ipinip|ipsec|nos|ospf|pcp|pim|pptp|snp|tcp|udp|\d)\s(\d*[.]\d*[.]\d*[.]\d*|any)\s(\d*[.]\d*[.]\d*[.]\d*|host)\s(\d*[.]\d*[.]\d*[.]\d*|host|object-group)\s(.*)\s(\d*[.]\d*[.]\d*[.]\d*|object-group|(eq|lt|gt|neq))\s(.*))|(^access-list\s(.*)\sextended\s(permit|deny)\s(ah|eigrp|esp|gre|icmp|icmp6|igmp|igrp|ip|ipinip|ipsec|nos|ospf|pcp|pim|pptp|snp|tcp|udp|\d)\s(\d*[.]\d*[.]\d*[.]\d*|any|host)\s(\d*[.]\d*[.]\d*[.]\d*|host)\s(\d*[.]\d*[.]\d*[.]\d*|host|object-group|any)\s(\d*[.]\d*[.]\d*[.]\d*|))|(^access-list\s(.*)\sextended\s(permit|deny)\s(ah|eigrp|esp|gre|icmp|icmp6|igmp|igrp|ip|ipinip|ipsec|nos|ospf|pcp|pim|pptp|snp|tcp|udp|\d)\s(\d*[.]\d*[.]\d*[.]\d*|any|host)\s(\d*[.]\d*[.]\d*[.]\d*|any)\s(\d*[.]\d*[.]\d*[.]\d*|any))|(^access-list\s(.*)\sextended\s(permit|deny)\s(ah|eigrp|esp|gre|icmp|icmp6|igmp|igrp|ip|ipinip|ipsec|nos|ospf|pcp|pim|pptp|snp|tcp|udp|\d)\s(\d*[.]\d*[.]\d*[.]\d*|any|host)\s(\d*[.]\d*[.]\d*[.]\d*|any))

It allows for Cisco ASA configuration parsing for lines that match crazy things like:

access-list <acl name> extended permit|deny <protocol> <ip|'any'> <subnet|'host'> <ip|'host'|'object-group'> <subnet|ip|group name> <subnet|'object-group'|('eq'|'lt'|'gt'|'neq')> <ip>

Though I'm sure I could write one a bit better <_<

@brutalhonesty Thanks, but that's an expression string. Expressions are currently limited to 1000 characters. Substitutions are currently limited to 100 chars.

[sparkyfen]

@gskinner Whoops, sorry, thanks. I did noticed though that some of the content got cut off when I paste the whole string into the site. Don't know why this is the case.

[gskinner]

@brutalhonesty hmm... ya, looks like your pattern is 1020 characters long. Maybe we should bump the max pattern length up to 1024. :)

[sparkyfen]

@gskinner That would be great! 😄

[deltamaster]

@gskinner @brutalhonesty Yes... It is just too easy to exceed the limit. My last case had around 200 characters. It would be great if the limit can be changed.

[gskinner]

I don't want to go too overboard with this, but maybe we will bump up to 2500 chars for patterns + 500 chars for substitution, and see if this comes up again. We will have to make sure to update the server at the same time (it also enforces these limits).

[gskinner]

We have bumped this up to 2500 characters for the Expression, and 500 characters for Substitution.

Feel free to reopen with use cases if this still isn't enough.

[sparkyfen]

Thanks!
