- Just a single huge commit. This has been developed over too long a
time, required many tiny changes across too many files and has seen too
many iterations to be separated into separate commits.
The original branch with all the messy commits will be kept around for
posterity
bb220ad0f2...adomasven:feature/react-item-tree
- Replaces XUL <tree> element across the whole zotero client codebase
with a custom supermegafast virtualized-table inspired by
react-virtualized yet mimicking old XUL treeview API. The
virtualized-table sits on top on a raw-to-the-metal,
interpreted-at-runtime JS based windowing solution inspired by
react-window. React-based solutions could not be used because they were
slow and Zotero UI needs to be responsive and be able to
display thousands of rows in a treeview without any slowdowns.
- Attempts were made at making this screen-reader friendly, but yet to
be tested with something like JAWS
- RTL-friendly
- Styling and behaviour across all platforms was copied as closely as
possible to the original XUL tree
- Instead of row-based scroll snapping this has smooth-scrolling. If
you're using arrow keys to browse through the tree then it effectively
snap-scrolls. Current CSS snap scroll attributes do not seem to work in
the way we would require even on up-to-date browsers, yet alone the ESR
version of FX that Zotero is on. JS solutions are either terrible for
performance or produce inexcusable jitter.
- When dragging-and-dropping items the initial drag freezes the UI for
a fairly jarring amount of time. Does not seem to be fixable due to
the synchronous code that needs to be run in the dragstart handler.
Used to be possible to run that code async with the XUL tree.
- Item tree column picker no longer has a dedicated button. Just
right-click the columns. The column preferences (width, order, etc) are
no longer handled by XUL, which required a custom serialization and
storage solution that throws warnings in the developer console due to
the amount of data being stored. Might cause temporary freezing on HDDs
upon column resize/reorder/visibility toggling.
- Context menu handling code basically unchanged, but any UI changes
that plugins may have wanted to do (including adding new columns) will
have to be redone by them. No serious thought has gone into how plugin
developers would achieve that yet.
- Opens up the possibility for awesome alternative ways to render the
tree items, including things like multiple-row view for the item tree,
which has been requested for a long while especially by users switching
from other referencing software
- We were updating global schema before migrating userdata, but a 4 → 5
upgrade involved a system.sql version bump, which wiped out itemTypes,
causing 'annotation' to not exist after the upgrade. This moves global
schema updates after userdata migration and bumps the global schema
version to repair DBs that were already upgraded and broken.
- A system.sql bump without a global schema update would result in empty
tables. This moves the global-schema-related tables to userdata.sql.
- The DB integrity check before userdata updates added in 5b9e6497a
could fail when coming from an older DB, because the checks assume
current schema. An integrity check is now done after a userdata update.
(We were already skipping the new table/index reconciliation stuff. If
old DBs are discovered to have problems that would cause a migration
step to fail, we'll fix those explicitly in the steps.)
Also:
- Make sure `version` is `versionNumber` in the `fields` table. It was
changed with a system.sql bump in 5.0, but hard-coded fields were later
removed from system.sql in favor of schema.json, meaning that anyone who
upgraded from 4.0 after that would never have `version` removed and so
would have both fields (one from before and one from schema.json).
This removes the feed processor's feature of converting enclosure MIME types to
a textual type description. This is not used by Zotero and removes an XPCOM
dependency.
This imports Mozilla's feed processor which has been removed upstream as part of
Firefox 66. Some changes are likely needed before this will actually run in
Zotero.
The page index needs to be per-person in group libraries, and it should
still work in read-only libraries, so it doesn't make sense to store it
on the item. This uses a synced setting in the user's library instead.
```
var noteContents = item.note; // was item.getNote()
var schemaVersion = item.noteSchemaVersion;
item.setNote(contents) // default to Zotero.Notes.schemaVersion
item.setNote(contents, schemaVersion) - explicit version
```
This lays the groundwork for moving collections and searches to the
trash instead of deleting them outright. We're not doing that yet, so
the `deleted` property will never be set (except for items), but this
will allow clients from this point forward to sync collections and
searches with that property for when it's used in the future. For now,
such objects will just be hidden from the collections pane as if they
had been deleted.
ConcurrentCaller wasn't waiting properly if start() was called again
while it was pausing, so 429 caused an immediate retry, which is pretty
much exactly what you don't want a 429 to do.
