in thread 5.10.0 regex slowdown

See those BRANCHJ EXACT LONGJMP tuples? They are confusing the optimiser so that it doesnt recognize this as a trie'able sequence. Ill have to think about what i can do about that.

I doubt ill have time soon tho.

Offline ysth mentioned a cool suggestion:

[2008-02-22 01:45] <ysth1> I ended up dividing my list into three diff
+erent regexes and used them like (?:(??{$rxa})|(??{$rxb})|(??{$rxc}))
[download]

Which isnt ideal but better than no trie at all. Sorry about this. :-(

Can I take it that you have the information you were seeking and I can ditch the nearly one GB of debug trace that took nearly 8 hours to produce? `2008-02-21 20:01 1,062,566,473 trie.log` [download] Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

Ah, yes. For sure. I didnt need that much anyway. :-) Im pretty sure youll find that most of that is going to be match debug output, which is not what i wanted, i just wanted a snippet of the compiled pattern dump. Sorry about that. --- $world=~s/war/peace/g	[reply]
