Thumbnails are normally created on demand, e.g. when processing the format codes in a post's body text.
Normally, the temporary URL is only used once to generate thumbnails ad-hoc. However, when cache is
enabled, a reference to the asset may be used in a cached version of a formatted body text, skipping
the normal thumbnail generation routine.
When an asset is replaced, currently, all thumbnails are removed and references to them are removed
from the database. In case the asset is still referenced in a cached formatted body text, this could lead
to an error when requesting the thumbnail, as the thumbnail request is no longer present in the system.
As we do not know what posts use particular assets at this point in the code, it is best to work around this
issue by unsetting the thumbnail filenames rather than deleting the entries outright. This effectively
generates them again on the next request.
In the future, we should aim to keep track of what posts make use of assets, so cache may be invalidated
in a more targeted way.
Bug as reported by Yorick: When two Assets have the same capture
date, a bug occurs in the interface where the user gets stuck in
a loop when moving to the next image.
This patch uses the primary key as a fallback when ordering the
images by capture date. This way, the asset ordering is complete
and it should resolve the bug.
* Removed support for row classification. Use of CSS is preferred.
* Removed support for disabling/enabling columns via a property. Unset as needed.
* Removed support for passing and inheriting a cell width by column. Header width suffices.
This saves both disk space and bandwidth by compromising a little on quality.
Only thumbnails are affected; full-size images are still saved in full detail.
Previously, a NotAllowedException would be thrown if an invalid session
was encountered. However, these exceptions were not caught, and hence
would yield a fatal uncaught exception error.
At this point in Kabuki, the ErrorHandler class has not been registered yet
for error handling purposes. This error is therefore not visible if the PHP
ini directive 'display_errors' is set to 'Off'. As this is the default
production value, the script would fail with a blank page in such cases.
This code is used to efficiently determine the most saturated colour in an image,
Kabuki uses this as the highlight colour on a page, but this styling has always
been disabled in HashRU Pics. Hence, we can safely remove the code, freeing up
some CPU cycles in the process. ;-)
The ConfirmDelete page now uses parts of the photopage. The
Confirmation dialog is its own template which is based on Alert.
The database now updates the album thumb to the most recent
addition to the album, when the album thumb asset is being deleted.
When there are no pictures left in the album 0 will be set.
