ZBX-5127 there is one problem.
For example I wrote incorrect regexp "^(?\/proc)"
When I'm trying to save it in 2.0 branch - I'm getting an error:
"preg_match(): Compilation failed: unrecognized character after (? or (?- at offset 3 [include/forms.inc.php:1766]"
Note - unfortunately it's even possible to save it (I mean 2.0.* here), which also not very good, I'd prefer it should NOT be possible.
But in trunk branch there NO any warnings/errors, and when I open "Test" tab I see only a "progress bar" which newer ends.
So, sort of regression
