Invalid routing pattern: GET / about selfoss

[SSilence]

Hm, a strange behaviour.

Have you set the base url in config.ini?
Have you set the RewriteBase in the .htaccess?

Best regards
Tobi

[Creat1veM1nd]

Yes, I set both and also tried different vways.

The URL to my selfoss installation is:

http:///misc/selfoss

So I tried /misc/selfoss and misc/selfoss
I also tried both variations with an / at the end.

No luck. Still the same message.

[SSilence]

Which webserver do you use? The three /// seems to be wrong.

[Creat1veM1nd]

Seems my post was formatted wrong. It should have been

http://myserver.tld/misc/selfoss

[SSilence]

Which webserver environment do you use?

[Creat1veM1nd]

PHP 5.3.13 (CGI / FastCGI)
Apache

[SSilence]

Are you using VirtualHost config? I have no idea what the reason could be. What does the apache access/error log say?

[cgutteridge]

It may be the PCRE version. https://groups.google.com/forum/?fromgroups=#!topic/f3-framework/7tfAuEPh_wY

[SSilence]

Hm, that could be the reason. WHich PCRE version do you use? Its listed in the phpinfo output.

I use the 8.12. Regarding the thread cgutteridge have posted you need at least version 8.

[cgutteridge]

My version is 6.6 and doesn't work with the latest version of F3 which is vexing because up until now it was a pretty low stress tool. This additional requirement is not achievable as we've 100+ sites on that server so shifting versions on a library isn't a minor risk.

[Creat1veM1nd]

My pcre is 6.6. Since it is a managed server, I am not able to update it by myself.

error.log says the same as I posted in my first post. sadly no further info.

[SSilence]

In this case selfoss depends on the fat free php framework and how they use the php libraries. I can understand the update problem.

I have updated the fat free php framework to the newest Version 3.0.5. Please check whether the newest version solves the problem. Just upload the files from selfoss/libs/f3.

[Creat1veM1nd]

I uploaded the framework. Sadly the error is still there:

Internal Server Error

Invalid routing pattern: GET /

I would make sure that your redirection is working correctly.

Make a small test with a simple .htaccess:

RewriteEngine On
RewriteBase /misc/selfoss

RewriteRule (.*)in(.*) welcome.html

create a welcome.html and add a string, e.g.

test

If you open http://myserver.tld/misc/selfoss/index.html you should see the text of welcome.html.
If not, probably one option in the apache config is wrong. Could be AllowOverride None which should be AllowOverride All.

[Creat1veM1nd]

I did as you suggested. All worked. I opened index.html and got the "test" of welcome.html.

Seems as if redirection is working correctly.

[jwbargsten]

Hmm, it was worth a try.

[SSilence]

Sadly I can not change this behavior. Hope fatfree will update their lib and support this pcre version in the future.

[cyberscribe]

I had this identical problem, and was able to get f3 to work just fine with PCRE 6.x by making a simple change to the codebase. In lib/base.php, for every instance of preg_match, [preg_replace, and preg_split] I simply replaced the pattern for a horizontal space ( \h ) with the pattern for a general space ( \s ). So far, everything works great, and all my routes are routing once again.

EDIT: also need to address preg_replace and preg_split--bascially all instances of \h to become \s

@cyberscribe It would be very nice, if you colud attach a pull request or let us otherwise know, which changes you made to the code.
I tried to replace \h by \s but that didnt work, as expected. At first, everything seems to work, but as soon, as I added the first rss feed, I got the following errror:

internal Server Error

preg_match_all() [function.preg-match-all]: Compilation failed: unrecognized character after (?< at offset 3

[cyberscribe]

Hi,

Attached is a patch. Hope it helps. Worked for me.

Best,
Robert

Thank you @cyberscribe , I wasted all morning trying to get PCRE updated, and this fixed it no problem.

[cyberscribe]

Glad it helped @mrfrasier !

[jtojnar]

The issue re-appeared for me after upgrade to PHP 7.1.11, opened an issue upstream f3-factory/fatfree-core#231

[jtojnar]

Apparently it is caused by cross-contamination by PCRE symbols from Apache.
