[pyup-bot]

This PR updates Lektor from 3.3.0 to 3.3.4.

Changelog

3.3.2

Features

Command Line

- Enabled the [Jinja debug extension][jinja-dbg-ext] when the
`LEKTOR_DEV` env var is set to 1 and `lektor server` is
used. ([984][])

License

- The wording in the LICENSE file was standardized to that of the
current [BSD 3-Clause License][bsd]. ([972][])

Bugs

Markdown Renderer

- Fix overzealous HTML-entity escaping of link and image attributes. ([989][])

Admin API

- Fix a bug in `make_editor_session` when editing non-existant pages
with a non-primary alt. ([964][])
- Fix the ability to add an initial flowblock to a page. (Broken in 3.3.1.)
- Refactor API views to move business logic back into the `Tree`
adapter ([967][]). This fixes [962][].

Admin UI

- Changed the structure of the URLs used by the GUI single-page app ([976][]).
This fixes problems with the "edit" pencil when using alternatives ([975][]),
and issues when page ids include colons ([610][]).
- Other React refactors and fixes ([988][]).

Database

- Fix `Attachment.url_path` when _alternatives_ are in use. There is only
one copy of each attachment emitted — the `url_path` should always be
that corresponding to the _primary alternative_. ([958][])
- `Pad.get`, if not passed an explicit value for the `alt` parameter,
now returns the record for the _primary alternative_ rather than the
fallback record. Similarly, `Pad.root` now returns the root record
for the _primary alternative_. ([958][], [965][])
- Fix for uncaught `OSError(error=EINVAL)` on Windows when `Pad.get`
was called with a path containing characters which are not allowed
in Windows filenames (e.g. `<>*?|\/":`).

Builder

- Pages now record a build dependency on their datamodel `.ini` file.
- Fix sqlite version detection so that we use "without rowid" optimization
with current versions of sqlite. ([1002][])

Command Line

- When running `lektor dev new-theme`: fix check for ability to create symlinks
under Windows. ([996][])
- Fix _rsync_ publisher when deletion enabled on macOS. ([946][], [954][])

Tests

- Fix for test failures when git is not installed. ([998][], [1000][])

Refactorings

- Cleaned up `EditorSession` to split mapping methods (for access to
record data) to a separate class, now available as
`EditorSession.data`. ([969][])

Testing

- Cleaned up and moved our `pylint` and `coverage` configuration to
`pyproject.toml`. ([990][], [991][])

Admin UI

- Move frontend source from `lektor/admin/static/` to `frontend/`.
Compiled frontend code moved from `lektor/admin/static/gen/` to
'lektor/admin/static/`. ([1003][])

Packaging

- Omit `example` subdirectory, frontend source code, developer-centric
config files, as well as other assorted cruft from sdist. ([986][])
