modify file_scan_directory to include a regex for the nomask.

like the idea, but it's do for a re-roll

Rerolled patch for 7.x which I tested by installing drupal7 with this patch applied.
Installation was successfull.

I cannot seem to be able to upload a patch file. I browser my file (called something.patch) and click on "Attach" button, wait that the file is uploaded. I leave the mark in the "List" checkbox and then click on "Post Comment" button but still nothing!

Here is the patch (I'll try again to upload)

Patch still applies with some offset (the patch below is identical to #5, except with the offset fixed), tested and work. RTBC.

We should probably be using preg_match: #64967: Replace ereg with preg

#64967: Replace ereg with preg got committed. so this should definitely use preg_match.

using a preg_match() style regular expression. added a test.

re-rolled.

I fixed one typo and committed it to CVS HEAD. I'm marking this 'code needs work' until the module upgrade instructions have been updated. Thanks!

I had to rollback this patch because it breaks the installer. It didn't break any of the simpletests though. More proof that we should have a simpletest for the installer. Make this patch could be a driver for that.

Big +1, yes. This wouldn't have slipped through with an installation test.

Problem appears to be that the installer still tries to pass an array to the function, which treats it as an expression.

Question would be: Do we use is_array() to allow both regular expressions and arrays, or switch to regular expressions entirely in the calling functions?

boombatower is working on abstracting the testing.drupal.org install script into a core patch - it's hard to test the installer at the moment, because we don't let simpletest run it for security reasons.

However, the patch broke testing.drupal.org - and boombatower had to switch off the first test of reporting back as CNW due to it. So when that's actually switched on, it'd catch issues like this for now.

Arancaytar, i'm generally opposed to overloaded parameters. and having one parameter be only regular expressions and the other array or regular expression seems really annoying.

looks like the tests didn't get rolled back so here's a re-roll that fixes the install.php file.

I just backed out the tests since they were breaking SimpleTest. So this one needs to be re-rolled with the tests again.

okay, here's a re-roll that adds the tests back in and the fix for the install.php file.

re-rolling.

I think you might have been mixing patches here.

// changelog
+    * Drupal core no longer requires CREATE TEMPORARY TABLES or LOCK TABLES
+      database rights.

Shouldn't belong in the file.inc patch, unless they are related in a way I don't understand. ;)

not sure how that got in there. re-rolled without it.

Committed to CVS HEAD along with a code clean-up. Thanks!

The patch that went in missed an instance of file_scan_directory() in install.inc, which still contains an array instead of an regexp.

It breaks installation entirely. Attached patch to fix this.

warnings on install read "preg_match() expects parameter 1 to be string, array given"

This patch brings me through installation.

Thanks, committed. We'll need to re-submit a bunch of other patches for re-testing.

Oh, also, docs please! :D

Isn't it hilarious that after all the work that went into automated unit tests, it only means that if we do break HEAD, we get to spend hours submitting re-tests for hundreds of patches?

Okay, I suppose it's not that hilarious when you're the one who has to do that.

For documentation purposes:

This bug in HEAD has caused the testing bot to report a large number of failed to install HEAD.

http://drupal.org/node/224333#file_scan_directory_nomatch

sorry for all the fun with the test bot... seems like it might be a good thing to have it watch for commits and run the tests against a clean copy of the code before testing patches.

Yep. See #335122: Test clean HEAD after every commit. Jimmy tells me he has some code written for this, ready to go as early as tomorrow, which is great. :)
