Commits ------- 56c1e31 performance improvement in PhpMatcherDumper Discussion ---------- performance improvement in PhpMatcherDumper Tests pass: yes The code generation uses a string internally instead of an array. The array wasn't used for random access anyway. I also removed 4 unneeded iterations this way (when imploding, when merging and twice when applying the extra indention). A `preg_replace` could also be saved under certain circumstances by moving it. And there was a small code errror in line 139.

Commits ------- 77185e0 [Routing] Allow spaces in the script name for the apache dumper 6465a69 [Routing] Fixes to handle spaces in route pattern Discussion ---------- [Routing] Handling of space characters in the dumpers The compiler was using the 'x' modifier in order to ignore extra spaces and line feeds but the code was flawed: - it was actually ignoring all the spaces, not only the extra ones added by the compiler, - all the spaces were stripped in the php and apache matchers. The proposed fix: - do not use the 'x' modifier any more (and then do no add extra spaces / line feeds), - do not strip the spaces in the matchers, - escapes the spaces (both in regexs and script name) for the apache matcher. It also include [a small optimization](https://github.com/vicb/symfony/pull/new#L9L89) when the only token of a route is an optional variable token - the idea is to make the regex easier to read. --------------------------------------------------------------------------- by vicb at 2012-04-10T13:59:45Z @Baachi fixed now. Thanks. --------------------------------------------------------------------------- by Tobion at 2012-04-10T16:01:31Z +1, I saw no reason for pretty printing the regex in the first place (just for debugging I guess). @vicb since you want to make the regex easier to read, I propose the remove the `P` from the variable regex `?P<bar>`, which is not needed anymore in PHP 5.3 (and we only support PHP 5.3+ anyway). --------------------------------------------------------------------------- by vicb at 2012-04-10T16:08:36Z @Tobion could you make a PR to this branch for the named parameters ? --------------------------------------------------------------------------- by Tobion at 2012-04-10T16:12:34Z I can include it in #3754 because I'm about the add 2 more fixes to it anyway. But when I proposed to apply these fixes to 2.0 Fabien rejected it. So not sure what branch you want me to apply this. --------------------------------------------------------------------------- by vicb at 2012-04-10T16:25:38Z May be the best is to put it on hold while I am reviewing your PRs. There are already enough changes, we'll make an other PR after all have been sorted out. What's the difference between 3754 and 3810 ? (3810 + 3763 = 3754 ?) --------------------------------------------------------------------------- by Tobion at 2012-04-10T16:39:32Z Lol you forget to link the PR numbers. At first sight I thought it's some sort of mathematical riddle. Haha #3810 is for 2.0 = #3763 (already merged) + #3754 for master --------------------------------------------------------------------------- by vicb at 2012-04-10T16:52:18Z I didn't link on purpose... the question is if '=' means strictly or loosely equal (any diffs - beside master vs 2.0) ? --------------------------------------------------------------------------- by Tobion at 2012-04-10T17:06:04Z It just applies my changes to 2.0. Nothing more. So master still differs from 2.0 by the addional features that were already implemented (e.g. `RouteCollection->addCollection` with optional requirements and options). But since my changes are bug fixes (except the performance improvement in #3763 but that doesn't break anything and makes 2.0 easier to maintain) I thought they should go into 2.0 as well. --------------------------------------------------------------------------- by vicb at 2012-04-10T17:14:27Z @Tobion only bug fixes mean "only bug fixes". You should re-open a PR for 2.0 with "only bug fixes", you might want to wait for me to review 3754. --------------------------------------------------------------------------- by Tobion at 2012-04-10T17:21:00Z Without #3763 it's much harder to apply the bug fixes. And now that I found 2 more bugs which requiresome rewriting of the PhpMatcherDumper, I don't want to apply all the commits by hand again for 2.0...
