I'm working on tightening up some of the transaction code. In the
past it was default commit=True because I would launch the repl, do
something, and quit, so it was nice to have auto commit. But really
it makes more sense to have it default False and be explicit when
to commit.
In sqlite3, rollback without a savepoint undoes the entire pending
transaction stack, whereas I was just popping the last save.
This change makes it match real sqlite. Also the only current call
for rollback is in the @transaction decorator which is already
explicit.
At the moment, all of these functions are safe because they're
called with hardcoded tables determined by other code, not user input.
But while I was working in this area I felt it would be good to add
a safety check just in case.
This hook had a bug where you couldn't select text because every
time you push a button, including ctrl+a or shift+left/right, the
cursor position gets reset and then deselects immediately.
So let's only reset the content and cursor only when text changes,
so arrow keys and ctrl don't have any negative effects.
This was a dumb bug. Because the version was included in the pragmas
that get set on every load, the database was receiving the new
user_version simply by setting skip_version_check=False and letting
the regular pragmas load, so all future checks passed without
having to run the db upgrader.
Unfortunately, when adjusting the box's value, it causes the datalist
to disappear, and it only comes back after you press another key.
I can't figure out how to make the datalist reappear automatically
with js.
Now that all <a> tags are pointy, there is no need for this fake link.
Its only purpose was to make <a>s that had an onclick but no
url get the ol' pointy.
I'm not entirely happy with the way that native drag-and-drop looks,
the transparent bit that you hold while dragging looks dumb.
Will have to look into control / shift clicking to multiselect.
Also just using browser confirm() for now since I haven't made my
own dialog for that kind of thing yet.
