Description

« Hide

To fix ~~MDL-13792~~, the function get_file_url was added. This bug aims to make use of it in every possible place. I will send in a big patch later (starting with 1.8) for review.

There is a problem with links to rss files, as most of them are to /rss/file.php, not /file.php. See /blog/rsslib.php, line 41, for one case of this. Possibilities :
1) don't do anything, xml files shouldn't have non-ascii file names anyway
2) modify get_file_url to make a link to /rss/file.php in these cases
3) make a different function for rss links

I vote for #2. Petr? Eloy? What do you think?

About rss stuff, I answered my own question. I'll modify the function as it should, it's actually kinda obvious.. (sorry about the noise)

stuff like this should not go into 1.8 imo

That's where the original bug was reported and that's what I was trying to fix (~~MDL-13792~~). Why shouldn't that go into 1.8?

utf-8 is not officially supported in file names and will not be until 2.0 (or later)
we did not backport many more serious bugs into 1.8.x

To be 100% correct we should also bump up the requires version in modules.
Could you please make a patch against 19?

I like the idea of those all $CFG->slahsarguments conditions centralised in the new function. And 100% agree wit Petr about 1.9 being the proper target. Not sure if we need requires bumps (AFAIK we bumped before release, isn't it?). Easy to check, anyway.

Ciao

Here's a version of the patch against MOODLE_19_STABLE. I did this carefully, but I can't possibly test all cases, so .. this needs some more eyes.

Mat,

We are still having problems with Link to File Resource. Log snippet below:

Here's a new version of the patch, for 1.9. This one corrects (afaics) all calls using $CFG->slasharguments, adding new "types" to get_file_url where necessary.

I did go over it a few times, but it needs more reviews. Petr, Eloy?

I had a read through the patch without spotting anything out of place ... it looks OK to me. I think we should put it in and test it wider today before the release tomorrow.

Reminder: update $versions in modules where necessary

I'm not sure if this bug caused this, but I updated this morning and got the new htmlarea.php and coursefiles.php and I now see no directory structure in the insert image section of the editor.

I apologize if this isn't the correct bug to report this. Thanks.

Something is wrong in moodle/files/index.php now as well, when I try to download a file from the course files area I now get:

You don't have permission to access /moodlehttp://moodle/file.php/286/backupdata/backup-ejhs-cb1-20080519-2322.zip on this server.

Mathieu,

I just tested the updated files and they seem to work perfectly. Thanks for fixing it!
