Rsconnect-python

Added

- Added validation for required flags for the `rsconnect system caches delete` command.
- Added `--force` flag to `rsconnect content build run` command. This allows users
to force builds when a build is already marked as running. (630)

Added

- You can now deploy Gradio applications. This requires Posit Connect release 2024.12.0
or later. Use `rsconnect deploy gradio` to deploy, or `rsconnect write-manifest gradio`
to create a manifest file.

Changed

- The `rsconnect content build run --poll-wait` argument specifies an integral
number of seconds. It previously allowed fractional seconds. (608)

- Uses the public Connect server API endpoint `/v1/tasks/{id}` to poll task
progress. (608)

Removed

- Uncalled `RSConnectClient.app_publish()` function, which referenced an
obsolete workflow.

Added
- Added support for creating manifests for TensorFlow models.
- Added support for deploying TensorFlow models.

Added
- Added support for creating manifests for Shiny Express apps.
- Added support for deploying interactive Quarto dashboards that use Shiny Express syntax.

Changed

- When deploying Shiny for Python applications on servers using a version of
Connect prior to 2024.01.0, there is an incompatibility with
`starlette>=0.35.0`. When deploying to these servers, the starlette version
is now automatically set to `starlette<0.35.0`.

Fixed

- Quarto content is marked as a "site" only when there are multiple input
files. (552)

- Quarto content automatically ignores `name.html` and `name_files` when
`name.md`, `name.ipynb`, `name.Rmd`, or `name.qmd` is an input. (553)

- Patterns provided to `--exclude` allow NT-style paths on Windows. (320)

Removed

- Python 3.7 support.

Added
- Added support for deploying Shiny express apps.
- Added support for deploying Shiny Express applications.
- Added a `--retry` flag to the `rsconnect content build run` command to re-run
builds for all content in the NEEDS_BUILD, ABORTED, ERROR, or RUNNING state.

Changed
- Improved the error and warning outputs when options conflict by providing the source
from which the values have been determined. This allows for faster resolution of issues
when combinations of stored credentials, environment variables and command line options
are used.
- Updated verbose mode to output the source of all options being used when processing the
CLI command.

Fixed
- Interrupting a long-running `rsconnect content build run` command with `^C`
will now update the local state file before attempting graceful cleanup. This
should help prevent users from getting stuck a "build already running" state.
See [467](https://github.com/posit-dev/rsconnect-python/issues/467) for details.

- Addressed an error which occurred when attempting to create manifests for
Quarto documents. (534)

Fixed
- The `https_proxy` environment variable is recognized as a synonym for
`HTTPS_PROXY`.
- When adding a new server, the initial request now includes an
authorization header containing the API key. This is needed
for Connect installations behind a proxy that only passes
authenticated requests.
- Common environment directories (`env, venv, .env, .venv`) are no longer
excluded by name. Environments are detected by the presence of a python
executable in `bin` or `Scripts` and excluded.
- Lines output from `pip freeze` which start with [notice] are filtered out from the generated `requirements.txt`.

Added
- Added support for the `no_proxy` or `NO_PROXY` environment variables to specify
hosts that should not be accessed via proxy server. It's a comma-separated list
of host or domain suffixes. For example, specifying `example.com` will
bypass the proxy for example.com, host.example.com, etc.
- If an entrypoint is not specified with `--entrypoint`, rsconnect-python will try
harder than before to choose an entrypoint file. In addition to the previously
recognized filename patterns, the file patterns `app-*.py`, `app_*.py`, `*-app.py`,
and `*_app.py` are now considered. However, if the directory contains more than
one file matching these new patterns, you must provide rsconnect-python with an
explicit `--entrypoint` argument.
- Added a new verbose logging level. Specifying `-v` on the command line uses this
new level. Currently this will cause filenames to be logged as they are added to
a bundle. To enable maximum verbosity (debug level), use `-vv`.
- Added a verification step to the deployment process that accesses the deployed content.
This is a `GET` request to the content without parameters. The request is
considered successful if there isn't a 5xx code returned (errors like
400 Bad Request or 405 Method Not Allowed because not all apps support `GET /`).
For cases where this is not desired, use the `--no-verify` flag on the command line.
- Added the `deploy flask` command.
- Added the `write-manifest flask` command.

Changed
- Removing experimental support for Conda. Connect does not support restoring Conda environments.
