Instead of embedding the entire tag list in the search.html template
every single time, this script loads the tags from the new,
cache-enabled endpoint /all_tags.json. Then we can use html5
datalists to create autocomplete forms on the search and photo pages.
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.
It was getting difficult to remember which of the normalizers
use None and which don't. So let's try to be a little more consistent
and just use empty sets, etc, so the caller can rely on receiving a
set instead of having to check for None.
Also renamed search parameter authors->author to be more in line
with the singular form of extension.
In order to achieve tag_musts, we break each of the musts down
into separate EXISTS queries for each of the matchable children.
Then we INTERSECT those, and finally do other filtering and
ordering as usual.
Initially inspired by the nuisance of having multiple photos
with the same timestamp because the system is too fast, this
feature could also be used to lessen disk load for running in
the background.
By default, photos with searchhidden do not appear in the search
results. This allows a small number of representative images from
a large album to appear in the results, while the rest can be
found on the album's page.
The same effect could be achieved with a tag and forbid search,
but tag searching has much higher cost and it would be more difficult
to implement as a default behavior without requiring lots of special
checks whenever listing tags etc.
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.
I decided I want to have higher precision especially because
batch inserts were having several photos with the same
created timestamp making orderby >= dumb.
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.
Because the function does not do any resolving or converting
to an absolute path, I feel the name 'normalize' is inaccurate
and could be misleading when read. This is more clear.
Primarily necessitated by unit testing. Running through the DB_INIT
is quite slow on disk, so this argument causes the sql to be done
on an in-memory database and all the other files are put into a
TemporaryDirectory.
Eventually I would like to have the other files be in-memory too
but that may be overcomplicated and underuseful.
More careful uncaching of the summed bytes, to minimize
recalculation. Fewer cases where the album itself
is removed from the photodb's getter cache.
This also helps the download link on album pages disappear if
the child albums don't actually have any photos.
