SID-01674: 5.1.3 - configure is breaking

Status:	Answered	TWiki version:	5.1.3	Perl version:	v5.10.1
Category:	CategoryInstallation	Server OS:	Ubuntu 2.6.32	Last update:	12 years ago

I managed to configure a fresh (ish) download once, but now when I try to again I receive the following message when clicking "Next" at the bottom of the configure screen.

Unmatched [ in regex; marked by <-- HERE in m/^[ <-- HERE ^\s\*?~^\$@%`/ at /var/www/twiki/lib/TWiki/Configure/Types/REGEX.pm line 55, <DATA> line 1.

Specifically the action I am trying to perform is to add a proxy. i.e. to set the values of {PROXY}{HOST} and {PROXY}{PORT}. But I tried a different kind of change to see if that was the problem and received the same message (setting {EnableEmail} to off).

Firstly, does anyone know what that error message is referring to please? Secondly, is it fixable? Or should I just download a fresher copy of TWiki and start again?

thanks in advance, Greg

Discussion and Answer

Possible issue: Maybe you run into TWikibug:Item7067. This has been fixed in your TWiki- 5.1.3 version, but can be an issue if your LocalSite.cfg is from an older version. Manually cleanup the file before running configure. See bug item for detail.

Thanks Peter. Where are the regex variables stored? I tried looking for recently-modified files and couldn't find an obvious candidate. Re' LocalSite.cfg I deleted it and started fresh, letting 'configure' itself create a new one and the problem still recurs.

I am going to try 5.1.4 anyway, but still this is bugging me. If I have the same issue with 5.1.4 I will create a new question.

cheers, Greg

Again, not sure if the known regex issue is your issue. Edit your Localsite.cfg file and search for (?^:. If you find (?^:(?^:SOMETHING)), fix it so that only the SOMETHING remains.

I looked again, TWikibug:Item7109 is most likely your issue. Patch lib/TWiki/Configure/Types/REGEX.pm or upgrade to TWiki-5.1.4.
