When refreshing, if fewer than 100 tags to show, just create them from
scratch instead of updating the full set. Otherwise, remove the full set
from DOM and add it back in after updates to avoid reflows (from #1204).
There are various things that could be done to optimize this further
(avoiding unnecessary sorting during full refreshes, calculating a hash
of the full set and not updating it every time), but we should probably
just replace it with @tnajdek's React version first.
Closes#1204
Changes `libraryTreeView::addEventListener('load')` and similar to
`libraryTreeView::onLoad.addListener(listener, once)`, etc. `once` is an
optional boolean that, when true, causes the listener to fire once and
then be removed. This is implicit for 'load'.
'load' maintains its special behavior of running immediately if the
treeview has already been loaded.
Also adds `waitForLoad()` and `waitForSelect()` functions that return
promises on event completion, since most uses of those events were just
resolving deferreds.
TODO: Add text fields for controlling number of items and chunk size
(Chunk size should be small for testing UI interactions and performance
but large for generating lots of data.)
For building up a big library and testing UI interaction during writes
To use, load chrome://zotero/content/tools/data_generator.html in
Firefox (for now).
Could be improved a bit to add other kinds of data (collections,
child items, relations)
The items list is generated from the database (via search), but new
items may have been added to the database but not yet been registered,
causing unloaded-data errors during sorting. Avoid that by not showing
unregistered items when generating the items list.
Additional protections are necessary -- it's still possible to get
errors, and maybe a crash, if an item has been registered but not yet
fully loaded -- but this addresses the most common one.
We could monkey-patch a finally function in connectors as described in
this gist https://gist.github.com/jish/e9bcd75e391a2b21206b , but it
appears to silence propogation of unhandled rejections
and it could later come back to bite us in the butt.
Native and proper support for finally is, however, planned in ES7.
When dragging an item to another library, we have to check if there's a
linked item in the target library, but items might not yet be laoded in
the other library, so item.getLinkedItem() can fail with "Item [n] not
yet loaded].
Fixing required asyncifying the follow functions:
- Zotero.Item::getLinkedItem()
- Zotero.Collection::getLinkedCollection()
- Zotero.URI.getURIItem()
- Zotero.URI.getURICollection()
- Various integration functions
As noted in 27cb099c82, import translators should be rewritten to return
a promise from doImport() and wait for promises from successive
item.complete() calls. They should then be marked as minVersion: "5.0"
to be handled properly by this new code.
(But this tries to account, albeit with somewhat worse behavior, for
translators that haven't been rewritten and sandboxes without Promise
(which is currently the case with child sandboxes in the client).)
(Oh, and I haven't tested this at all in the connectors.)
Function that automatically follows Link headers and makes additional
requests as necessary, feeding the XMLHTTPRequest object from each
request to a reducer function.
- Archive remotely missing that user chooses to keep
- Ignore archived groups that don't existing remotely
- Unarchive groups that become available again
This can happen because objects are uploaded in batches, but the version
number from the last batch is used for all objects (since
APIClient.uploadObjects() handles batching internally).
Previously on Windows, where we don't have /bin/mv, we were recursing
into the data directory and copying files individually, which is very
slow, so automatic migration was disabled. Instead, try moving
directories with OS.File.move() with the `noCopy` flag. Moving
directories is technically unsupported by OS.File, but probably only
because of the possibility of a cross-volume copy (which is only
implemented for some platforms), and using `noCopy` hopefully prevents
that. If someone does have their data directory or storage directory on
a different volume, the migration might be quite slow, but leaving a
data directory behind in the Firefox profile directory (where it can be
easily misplaced with a seemingly unrelated Firefox reset) is worse.
E.g., moving 3,600 items to the trash now takes 4 seconds instead of 62
Instead of saving each item, update internal state and database directly
(which is more brittle but worth it). Also avoid unnecessary sorting
after removing an item from the items tree.
This allows for imported items to be saved individually instead of being
saved in a batch after processing the entire imported file (which for
large imports would hang the UI, even if the actual saving was
asynchronous). This also fixes the progress meter during asynchronous
saves.
To take advantage of this, import translators will need to return a
promise when available (using the native Promise object) from doImport()
and wait for optional promises from item.complete().
The logic here can probably be streamlined further. (E.g., we might be
able to say that item.complete() always returns a promise.) It's
complicated by the fact that, at the moment, Promise isn't available in
child sandboxes, though this can probably be fixed.
Tests forthcoming, but they require a translator that supports this,
which needs to be committed separately.
