Revisions for ansel/rss.php

Get rid of all this 'requestedView' nonsense now that it's fixed the right
way :)

consistent comment style, minor cs/style tweaks

Remove references to deprecated list.php.

Well, here goes. Another sweeping change to the data storage in Ansel.
This commit has Ansel using the new Horde_Share hierarchical sql driver,
and thus requires Horde_Share_sql_hierarchical.php which is now in FW_3.

To upgrade an existing installation, you need to first run the
2008-04-28_add_sql_share_tables.sql script on your database, and then run
then *_sql_share_migration.php script which will move all the gallery data
completely out of the datatree for good!  This script will not delete any
data unless you tell it to.  Also be aware that if you have hacked ansel's
config to use seperate datatree tables for ansel then you will need to edit
the script with the correct table names.

Make sure to pass the requestedView parameter whenever we are requesting
a gallery view url

Remove hasChildren and replace with the newer hasSubgalleries()
along with some other code optimizations.

Some more rewrite rules, add lots more Ansel::getUrlFor() calls in place
of Horde::applicationUrl(). Some of these I missed the first time, some
I didn't have the getUrlFor controller ready...

Remove Horde_Template usage

- A whole bunch of pretty url generation
- Activate the new Ansel_View_List in place of list.php (list.php will remain
for now until further testing, but it will be removed shortly)
- Added additional rewrite rules so we have pretty urls for the general
groupings as well

Fixes for pretty urls in rss feeds

No need for a function call to get the gallery id now that galleries are
seperate from their share object. Remove Ansel_Gallery::getId() and replace
with id instance variable. Saves a bunch of function calls, and is now another
similarity between Ansel_Image and Ansel_Gallery objects.

Allow rss.php to take a gallery slug, add rewrite rules for generating rss
feeds from pretty urls such as:
ansel/user/mike/rss
ansel/gallery/galleryslug/rss
ansel/gallery/gallery_id/rss

Don't need gallery style for rss feeds, we always use 'ansel_default'.
And a few more  places here to pass the 'ansel_default' style

Be more diligent about passing the available style information around
so we can check the existence of a particular view without having to
read image data from the database and instantiate an Ansel_Image object
each time

Bug: 6222
Submitted by: Duck

Statically cache Ansel_Storage::getImage() calls since they can often
be called multiple times per page load and from different scopes. Also
have to add reference operators now to be sure that only a single copy of
the image object is ever operated on per page load in PHP4.

Bug: 6219
Submitted by: Duck

The mother of all Ansel commits.  This removes all the gallery attributes
from the datatree, leaving only permissions and hierarchical information in
datatree.

To upgrade, first run the 2008_01_07_add_galleries.sql script to create
the gallery table and then run the sql_galleries.php script.  The script
does *NOT* delete any data from the datatree - it only creates the new
structure. Another (upcoming) upgrade script will remove the data from
the datatree once this is more thoroughly tested.

Bug: 6101

Happy New Year

Ensure we use the correct mime type. Ansel_Image::type is only valid for the
original, 'full' view...otherwise, we assume the image is in the format of
$conf['image']['type']

Standardize on using 'photos' instead of 'images'.

Use $conf['server']['name'], and refer to images "on" a server
Bug: 5915

One more time...fix logic here to allow for the fact that there might not
be a cache object.

$cache is not set unless we turn it on in ansel's config.

If we are requesting a gallery feed, make sure the id is at least numberic
before attempting to retrieve it.

Look for images in any subgalleries when creating a rss feed for an empty gallery.

Start slowly moving towards allowing galleries to specify named styles.
This commit doesn't add much functionality...just renaming some variables and methods to better reflect where we are going.

- Don't assume we always want a prettythumb just because we're capable of them. (In particular for rss feeds we always return a 'normal' thumb).

- Use a Polaroid stack effect for default gallery images if we are capable of using prettythumbs...provide ability for user to regenerate the gallery default image from the gallery property page.

Probably still some tweaking to do to image sizes and things, plus I want to add per-gallery settings for prettythumb vs thumb but I wanted to get this into CVS before I went too much further :)

cache the rendered rss templates

typo

Add media:thumbnail node

Need to encode this since it may contain a query string

Add tag-based rss stream
Tweak some title text

More descriptive gallery feed title

Add rss2 specific tag for atom element

Add rss version 2.0 template (with support for media namespace extensions).

Don't restrict to top level galleries

fix stream_rss template tag by removing values I had in there for testing

use fullname from identity if we can get it.

use most recent Ansel_Image::uploaded time as the last_modified time for feed

Add channel images to rss feed, and some code cleanup, catch errors, ws, wrap etc...

Add a user filter to rss feed

Use Ansel_Image::uploaded property of the most recent image as the modified time
for the feed....and update some comments.

More descriptive feed title

Support for (default) 'all' filter for rss feed.
Still kinda rough.  Eventually, what I'd like is for the link to bring you to a search results page containing only the items in any of the feeds (similar to the tag results page) but that will wait until I can look at refactoring some of the search results code to be more flexible.

Check permissions / catch error

First stab at rss feed for Ansel. Currently, only works for requesting feed for particular gallery - still todo by user, tag, category, and all plus rss2 template etc...
