I'm not convinced it's the length of the filename. :)

Are there other pages with a colon (:) in the title that have the same problem? If you can try, does the problem still happen after replacing the colon by a dash or such?


Confirming the problem, though the backtrace that I get is slightly different:

I had disabled all Extensions, to check if the Problem is really a Mediawiki bug. That only changes the Stacktrace, but not the error, as you can see.

Normally we dont have problems with pagenames containing :"'! or any other symbols.

No idea yet what exactly is going wrong here, sorry. 
I recommend to also post to https://www.mediawiki.org/wiki/Project:Support_desk to get more input by people with potential ideas.

We have some more Pages that dont work, but we dont know why:

Is there an example of a page with a colon that works?

This one works:
http://sofis.gesis.org/sofiswiki/Test!test

Sorry sometimes i dont read well :-)

so this one here works http://sofis.gesis.org/sofiswiki/Test!,.;:%27%60%C2%B4%5E%22test

I think it has something to do with the length of the string before the colon.

Have a look, this one makes an Error:

http://sofis.gesis.org/sofiswiki/Auswirkungen_existenzieller_angste_von_Soldaten_und_Familienangehorigen_im_Kontext_von_Auslandseinsatzena_der_Bundeswehr_auf_die_Beziehungsqualitat_und_ihre_Bedeutung_f%C3%BCr_die_gealingende_Partanearschaft_sowie_die_Ehe-_und_Familien:pastoral_Resilienzf

And this is the same string, just the colon moved one to the left and it works:

http://sofis.gesis.org/sofiswiki/Auswirkungen_existenzieller_angste_von_Soldaten_und_Familienangehorigen_im_Kontext_von_Auslandseinsatzena_der_Bundeswehr_auf_die_Beziehungsqualitat_und_ihre_Bedeutung_f%C3%BCr_die_gealingende_Partanearschaft_sowie_die_Ehe-_und_Familie:npastoral_Resilienzf

I think you're looking at a title length problem.  For example, installation works fine with http://winkyfrown.com/wiki/index.php/Auswirkungen_existenzieller_angste_von_Soldaten_und_Familienangehorigen_im_Kontext_von_Auslandseinsatzena_der_Bundeswehr_auf_die_Beziehungsqualitat_und_ihre_Bedeutung_f%C3%BCr_die_gealingende_Partanearschaft_sowie_die_Ehe-_und_Familien:abcdefpastoral_Resilien

but fails on

http://winkyfrown.com/wiki/index.php/Auswirkungen_existenzieller_angste_von_Soldaten_und_Familienangehorigen_im_Kontext_von_Auslandseinsatzena_der_Bundeswehr_auf_die_Beziehungsqualitat_und_ihre_Bedeutung_f%C3%BCr_die_gealingende_Partanearschaft_sowie_die_Ehe-_und_Familien:abcdefgpastoral_Resilien but fails on http://winkyfrown.com/wiki/index.php/Auswirkungen_existenzieller_angste_von_Soldaten_und_Familienangehorigen_im_Kontext_von_Auslandseinsatzena_der_Bundeswehr_auf_die_Beziehungsqualitat_und_ihre_Bedeutung_f%C3%BCr_die_gealingende_Partanearschaft_sowie_die_Ehe-_und_Familien:abcdefgpastoral_Resilien

(note the added "g" after the ":")

The one that works is 256 chars long, the one that doesn't is 257.

Note that the URL length is the URI-decoded portion.  Replacing ü with u still shows the problem.

I cannot believe this, because:

This one works:
http://sofis.gesis.org/sofiswiki/Der_U:mgang_des_Staates_in_Nordafrika/_Nahost_mit_militanter_Opposition_im_Zeitalter_euromediterraner_Kooperation_%28TP_1_im_Rahmen_des_Gesamtprojekts_%22Strategien_zur_langfristigen_Stabilisierung_der_euromediterranen_Partnerstaaten_in_Nordafrika/_Nahost:_in

This one not:
http://sofis.gesis.org/sofiswiki/Der_Umgang_des_Staates_in_Nordafrika/_Nahost_mit_militanter_Opposition_im_Zeitalter_euromediterraner_Kooperation_%28TP_1_im_Rahmen_des_Gesamtprojekts_%22Strategien_zur_langfristigen_Stabilisierung_der_euromediterranen_Partnerstaaten_in_Nordafrika/_Nahost:_in

The first string is longer and throws no error. The only different is that the first string has the colon at the sixth position of the page name and another at the end.

Hi,
i found a workaround for this problem. If I disable the memcache everything works fine. The Error Occurs if the memcache is too slow. The real Error occurs in MessageCache.php line 339:

$success = $this->mMemc->add( $statusKey, 'loading', MSG_LOAD_TIMEOUT );
