[Koha-devel] Rewrite of URLs, flushing all empty arguments

[David Cook]

First things first, Philippe, you haven’t given enough information about the problem. 

 

For instance:

http://localhost:8081/cgi-bin/koha/tools/letter.pl?op=delete_confirm <http://localhost:8081/cgi-bin/koha/tools/letter.pl?op=delete_confirm&branchcode=&module=suggestions&code=ACCEPTED> &branchcode=&module=suggestions&code=ACCEPTED

http://localhost:8081/cgi-bin/koha/tools/letter.pl?op=delete_confirm <http://localhost:8081/cgi-bin/koha/tools/letter.pl?op=delete_confirm&module=suggestions&code=ACCEPTED> &module=suggestions&code=ACCEPTED

 

On koha-testing-docker, which admittedly is a later version, neither of these raise an error, although the second link won’t work as expected. So you should look at the actual error message in your log, and try to work it out from there. It might be that it’s a known issue that’s been fixed upstream already. 

 

Not sure what you mean by “the connection page”. Is that the login screen for letter.pl or something else? 

 

When you say “the branchcode= disappears on landing”, it’s not clear what you mean. Take a look at the Network tab on your browser and see if there are any redirects. You can also increase the logging on your Apache to see what exactly it’s doing: https://httpd.apache.org/docs/2.4/mod/core.html#loglevel. 

 

Maybe that problem instance has some Javascript running that is interfering with the location URL. You can add breakpoints in your browser so that it pauses at certain points in the process of loading. 

 

My suggestion would be doing some hands-on troubleshooting. Work the problem. The truth is out there.

There are many layers interacting here.  First is apache recieving the request, where it passes through any apache modules that are loaded, then it's passed to cgi or fcgi (you haven't mentioned whether you have plack enabled, but you probably do), then it's passed to Koha's codebase.  There could be version differences between Debian and Ubuntu in either Apache modules or Perl CGI/FCGI modules that would cause an empty get variable to be dropped.  The perl module versions would be the first thing I'd check.

Hello all!

New issue (in 22.05 here, but might be anywhere):

 <https://v22-test-intranet.hapax.inlibro.net/cgi-bin/koha/tools/letter.pl?op=delete_confirm> https://somedomain.net/cgi-bin/koha/tools/letter.pl?op=delete_confirm&branchcode=&module=suggestions&code=ACCEPTED

When somedomain is onto one of our debian box (bullseye, 11), the branchcode= disappears on landing.  Be it on the connection page or letter.pl <http://letter.pl> , we do not have the branchcode= anymore, and the code throws an error (branchcode being undefined)

When running onto our laptops (Ubuntu) that doesn't happen.

We have no custom RewriteRule, so I'm trying to figure out WHERE this rewrite comes from.  

All suggestions welcomed,

Best regards,
