Foolproof file redirection
This solves an issue when our internal /attachment/{file_id} links are shortened with an remote shorteners (which caused the /attachment/{file_id} links to be saved to the File table and a thumbnail of a thumbnail being generated)
See merge request !98
The code was so involved there was even a comment asking for a refactor.
Now, File_redirection::where always returns a nice File_redirection
object instead of an array or string or nothing. The object is
either one which already existed or else a new, unsaved object.
Instead of duplicating "does it exist" checks everywhere, do it in
File_redirection::where. You either get what exists or something to save.
An unsaved File_redirection may be paired with an unsaved File.
You will want to save the File first (using ->saveFile()) and put the
id in File_redirection#file_id before saving.
If this merge throws exception on scripts/upgrade.php and you recently
tried a nightly (i.e. during 2015-02-19) then just go back a commit or two
and try again.
Or delete the duplicate entries. Find the entries like this:
SELECT COUNT(*), urlhash FROM file_redirection
GROUP BY urlhash
HAVING COUNT(*) > 1;
then for each urlhash (or come up with a smart SQL query) do:
DELETE FROM file_redirection WHERE urlhash='hashfrompreviousquery' LIMIT 1;
You'll have to remove duplicates more than once if you have >2 identical
urlhash entries. LIMIT -1 might do that for you. I'm not sure.
I used this hacky sed-command (run it from your GNU Social root, or change the first grep's path to where it actually lies) to do a rough fix on all ::staticGet calls and rename them to ::getKV
sed -i -s -e '/DataObject::staticGet/I!s/::staticGet/::getKV/Ig' $(grep -R ::staticGet `pwd`/* | grep -v -e '^extlib' | grep -v DataObject:: |grep -v "function staticGet"|cut -d: -f1 |sort |uniq)
If you're applying this, remember to change the Managed_DataObject and Memcached_DataObject function definitions of staticGet to getKV!
This might of course take some getting used to, or modification fo StatusNet plugins, but the result is that all the static calls (to staticGet) are now properly made without breaking PHP Strict Standards. Standards are there to be followed (and they caused some very bad confusion when used with get_called_class)
Reasonably any plugin or code that tests for the definition of 'GNUSOCIAL' or similar will take this change into consideration.
The parent class for our database objects, Managed_DataObject, has a
dynamically assigned class in staticGet which objects get put into,
leaving us with less code to do the same thing.
We will probably have to move away from the DB_DataObject 'staticGet'
call as it is nowadays deprecated.
common_shorten_links() can only access the web session's logged-in user, so never properly took user options into effect for posting via XMPP, API, mail, etc.
Adds an optional $user parameter on common_shorten_links(), and a $user->shortenLinks() as a clearer interface for that.
Tweaked some lower-level functions so $user gets passed down -- making the $notice_id param previously there for saving URLs at notice save time generalized a little.
Note also ticket #2919: there's a lot of duplicate code calling the shortening, checking the length, and reporting near-identical error messages. These should be consolidated to aid in code and translation maintenance.
This option may be useful for intranet sites that don't have direct access to the internet, as they may be unable to successfully fetch those resources.
When bogus SSL sites etc were hit through a shortening redirect, sometimes link resolution kinda blew up and the user would get a "Can't linkify" error, aborting their post.
Now catching this case and just passing through the URL without attempting to resolve it. Could benefit from an overall scrubbing of the freaky link/attachment code though...! :)

Users and administrators can set how long an URL can be before it's
shortened, and how long a notice can be before all its URLs are
shortened. They can also turn off shortening altogether.

Add User_urlshortener_prefs
Add a table for URL shortener prefs, a corresponding class, and the
correct mumbo-jumbo in statusnet.ini to make everything work.
Caching support will be added in future work after unit tests have been added.
* extlib: add PEAR HTTP_Request2 0.4.1 alpha
* extlib: update PEAR Net_URL2 to 0.3.0 beta for HTTP_Request2 compatibility
* moved direct usage of CURL and file_get_contents to HTTPClient class, excluding external-sourced libraries
* adapted GeonamesPlugin for new HTTPResponse interface
Note some plugins haven't been fully tested yet.
