It creates an internal message and an error of the form

Quantifier follows nothing in regex; marked by <-- HERE in m/* <-- HERE TopicName

I haven't tested it in 4.0 yet.

-- ML

I cannot reproduce this in twiki4

does not create any errors on my twiki4

-- KJL

Try TopicSearchText1

It breaks with both ~twiki4 and ~develop

---

TopicSearchText1 has this:

%SEARCH{"*Test*" regex="on" scope="topic" format="   * $topic"}%

(Cairo does the same for bad regexs, see TWiki:Sandbox.TestBadRegex).

%SEARCH{".*Test.*" type="regex" scope="topic" format="   * $topic"}%

Works ok.

Um, just because Cairo breaks it's OK that Dakar breaks too? And, oddly enough, it doesn't break as long as you don't say scope="topic". One way or the other, breaking is bad, especially since regexes are often quite difficult to get right.

-- ML

Reprioritized to normal as discussed in edin* meeting.

-- PTh

Setting this to enchancement. New wanted behaviour on bad regexps should be discussed in Codev.

-- SP

Setting to No Action. If user is using regular expressions, then the returned error is valid. No error is recorded to the logs.
