I found that the strict heirarchy was not satisfying the situation
where one tag is the intersection of two others, but we can only
pick one as the parent
For example, does red_jacket belong under clothes.red_clothes or
clothes.jackets? A search for "red_clothes AND jackets" might
give us someone wearing red pants and a black jacket, so this
definitely needs to be a separate tag, but picking only one
parent for it is not sufficient. Now, a search for red_clothes
and a search for jackets will both find our red_jacket photo.
The change also applies to Albums because why not, and I'm sure
a similar case can be made.
Unfortunately this means tags no longer have one true qualname.
The concept of qualnames has not been completely phased out but
it's in progress.
This commit is very big because I was not sure for a long time
whether to go through with it, and so much stuff had to change
that I don't want to go back and figure out what could be grouped
together.
Previously they were relative to the directory from which the client
was launched, meaning it usually started with ./_etiquette.
Now it should be more portable and less tight.
If a @transaction method makes calls to other @transaction
methods, and one of those nested calls makes a commit, and then
the outer call raises an exception, then the outer call will
not rollback properly because its savepoint is no longer in
the savepoint stack. So let's warn the user if that happens.
Should this raise an exception instead of just warn? Not sure,
I mean the data is already committed.
I didn't know about these! Now we don't have to roll all the way
back in case of problems. This allows for raising exceptions as
control flow since they won't undo unrelated stuff.
Any element with class clipboard_size will have its text updated;
Removed the call to on_pageload from save_ because it redundantly
causes a load. Separate those update hooks.
There was a bug where moving an album out of its determined parent
caused future digests to fail because I wanted to use the GroupExists
for control flow, but due to the @transaction decorator it was rolling
back the changes.
Moved some of the logical pieces of the function into subfunctions
as a visual and readability aid.
Appearing on search and album pages, the tray is where you can
remove items from your clipboard without having to click on its
checkbox -- that photo card may not even be on the current page.
add photo and search css for narrow screens; incorporate new expressionmatch kit; entry_with_history cursor moves to end; albums indicate total filesize; etc
