sits at the center of a growing ecosystem of open source tools aimed at making it as easy as possible to gather, analyze and publish interesting data. + +These tools are divided into two main groups: tools for building SQLite databases (for use with Datasette) and plugins that extend Datasette's functionality. + +Tools for creating SQLite databases +=================================== + +csvs-to-sqlite +-------------- + +`csvs-to-sqlite `__ lets you take one or more CSV files and load them into a SQLite database. It can also extract repeated columns out into a separate table and configure SQLite full-text search against the contents of specific columns. + +sqlite-utils +------------ + +`sqlite-utils `__ is a Python library and CLI tool that provides shortcuts for loading data into SQLite. It can be used programmatically (e.g. in a `Jupyter notebook `__) to load data, and will automatically create SQLite tables with the necessary schema. + +The CLI tool can consume JSON streams directly and use them to create tables. It can also be used to query SQLite databases and output the results as CSV or JSON. + +db-to-sqlite +------------ + +`db-to-sqlite `__ is a CLI tool that builds on top of `SQLAlchemy `__ and allows you to connect to any database supported by that library (including MySQL, oracle and PostgreSQL), run a SQL query and save the results to a new table in a SQLite database. + +dbf-to-sqlite +------------- + +`dbf-to-sqlite `__ works with `dBase files `__ such as those produced by Visual FoxPro. It is a command-line tool that can convert one or more ``.dbf`` file to tables in a SQLite database. + +markdown-to-sqlite +------------------ + +`markdown-to-sqlite `__ reads Markdown files with embedded YAML metadata (e.g. for `Jekyll Front Matter `__) and creates a SQLite table with a schema matching the metadata. This is useful if you want to keep structured data in text form in a GitHub repository and use that to build a SQLite database. + +Datasette Plugins +================= + +Datasette's :ref:`plugin system ` makes it easy to enhance Datasette with additional functionality. + +datasette-cluster-map +--------------------- + +`datasette-cluster-map `__ is the original Datasette plugin, described in `Datasette plugins, and building a clustered map visualization `__. + +The plugin works against any table with latitude and longitude columns. It can load over 100,000 points onto a map to visualize the geographical distribution of the underlying data. + +datasette-vega +-------------- + +`datasette-vega `__ exposes the powerful `Vega `__ charting library, allowing you to construct line, bar and scatter charts against your data and share links to your visualizations. + +datasette-json-html +------------------- + +`datasette-json-html `__ renders HTML in Datasette's table view driven by JSON returned from your SQL queries. This provides a way to embed images, links and lists of links directly in Datasette's main interface, defined using custom SQL statements. + +datasette-render-images +----------------------- + +`datasette-render-images `__ works with SQLite tables that contain binary image data in BLOB columns.

+.. code-block:: python
+
+    from datasette import hookimpl
+    import random
+
+    @hookimpl
+    def permission_allowed(action):
+        if action != "view-instance":
+            # Return True or False at random
+            return random.random() > 0.5
+        # Returning None falls back to default permissions
+
+This function can alternatively return an awaitable function which itself returns ``True``, ``False`` or ``None``. You can use this option if you need to execute additional database queries using ``await datasette.execute(...)``.
+
+Here's an example that allows users to view the ``admin_log`` table only if their actor ``id`` is present in the ``admin_users`` table. It aso disallows arbitrary SQL queries for the ``staff.db`` database for all users.
+
+.. code-block:: python
+
+    @hookimpl
+    def permission_allowed(datasette, actor, action, resource):
+        async def inner():
+            if action == "execute-sql" and resource == "staff":
+                return False
+            if action == "view-table" and resource == ("staff", "admin_log"):
+                if not actor:
+                    return False
+                user_id = actor["id"]
+                return await datasette.get_database("staff").execute(
+                    "select count(*) from admin_users where user_id = :user_id",
+                    {"user_id": user_id},
+                )
+
+        return inner
+
+See :ref:`permissions` for a full list of permissions that are included in Datasette core.

+The view functions can take a number of different optional arguments. The corresponding argument will be passed to your function depending on its named parameters - a form of dependency injection.
+
+The optional view function arguments are as follows:
+
+``datasette`` - :ref:`internals_datasette`
+    You can use this to access plugin configuration options via ``datasette.plugin_config(your_plugin_name)``, or to execute SQL queries.
+

+
+``scope`` - dictionary
+    The incoming ASGI scope dictionary.
+
+``send`` - function
+    The ASGI send function.
+
+``receive`` - function
+    The ASGI receive function.
+
+The function can either return a ``Response`` or it can return nothing and instead respond directly to the request using the ASGI ``receive`` function (for advanced uses only).

+.. _internals_response:
+
+Response class
+~~~~~~~~~~~~~~
+
+The ``Response`` class can be returned from view functions that have been registered using the :ref:`plugin_register_routes` hook.
+
+The ``Response()`` constructor takes the following arguments:
+
+``body`` - string
+    The body of the response.
+
+``status`` - integer (optional)
+    The HTTP status - defaults to 200.
+
+``headers`` - dictionary (optional)
+    A dictionary of extra HTTP headers, e.g. ``{"x-hello": "world"}``.
+
+``content_type`` - string (optional)
+    The content-type for the response. Defaults to ``text/plain``.
+
+For example:
+
+.. code-block:: python
+
+    from datasette.utils.asgi import Response
+
+    response = Response(
+        "This is XML",
+        content_type="application/xml; charset=utf-8"
+    )
+
+The easiest way to create responses is using the ``Response.text(...)``, ``Response.html(...)``, ``Response.json(...)`` or ``Response.redirect(...)`` helper methods:
+
+.. code-block:: python
+
+    from datasette.utils.asgi import Response
+
+    html_response = Response.html("This is HTML")
+    json_response = Response.json({"this_is": "json"})
+    text_response = Response.text("This will become utf-8 encoded text")
+    # Redirects are served as 302, unless you pass status=301:
+    redirect_response = Response.redirect("https://latest.datasette.io/")
+
+Each of these responses will use the correct corresponding content-type - ``text/html; charset=utf-8``, ``application/json; charset=utf-8`` or ``text/plain; charset=utf-8`` respectively.
+
+Each of the helper methods take optional ``status=`` and ``headers=`` arguments, documented above.

 A **resource** is the item the actor wishes to interact with - for example a specific database or table. Some actions, such as ``permissions-debug``, are not associated with a particular resource.
 
+Datasette's built-in view permissions (``view-database``, ``view-table`` etc) default to *allow* - unless you :ref:`configure additional permission rules ` unauthenticated users will be allowed to access content.
+
+Permissions with potentially harmful effects should default to *deny*. Plugin authors should account for this when designing new plugins - for example, the `datasette-upload-csvs `__ plugin defaults to deny so that installations don't accidentally allow unauthenticated users to create new tables by uploading a CSV file.
+
+.. _authentication_permissions_allow:
+
+Defining permissions with "allow" blocks
+----------------------------------------
+
+The standard way to define permissions in Datasette is to use an ``"allow"`` block. This is a JSON document describing which actors are allowed to perfom a permission.
+
+The most basic form of allow block is this:
+
+.. code-block:: json
+
+    {
+        "allow": {
+            "id": "root"
+        }
+    }
+
+This will match any actors with an ``"id"`` property of ``"root"`` - for example, an actor that looks like this:
+
+.. code-block:: json
+
+    {
+        "id": "root",
+        "name": "Root User"
+    }
+
+Allow keys can provide a list of values. These will match any actor that has any of those values.
+
+.. code-block:: json
+
+    {
+        "allow": {
+            "id": ["simon", "cleopaws"]
+        }
+    }
+
+This will match any actor with an ``"id"`` of either ``"simon"`` or ``"cleopaws"``.
+
+Actors can have properties that feature a list of values. These will be matched against the list of values in an allow block. Consider the following actor:
+
+.. code-block:: json
+
+    {
+        "id": "simon",
+        "roles": ["staff", "developer"]
+    }
+
+This allow block will provide access to any actor that has ``"developer"`` as one of their roles:
+
+.. code-block:: json
+
+    {
+        "allow": {
+            "roles": ["developer"]
+        }
+    }
+
+Note that "roles" is not a concept that is baked into Datasette - it's a convention that plugins can choose to implement and act on.
+
+If you want to provide access to any actor with a value for a specific key, use ``"*"``. For example, to match any logged-in user specify the following:
+
+.. code-block:: json
+
+    {
+        "allow": {
+            "id": "*"
+        }
+    }
+
+You can specify that unauthenticated actors (from anynomous HTTP requests) should be allowed access using the special ``"unauthenticated": true`` key in an allow block:
+
+.. code-block:: json
+
+    {
+        "allow": {
+            "unauthenticated": true
+        }
+    }
+
+Allow keys act as an "or" mechanism. An actor will be able to execute the query if any of their JSON properties match any of the values in the corresponding lists in the ``allow`` block.

+Some permission checks are carried out against :ref:`rules defined in metadata.json `, while other custom permissions may be decided by plugins that implement the :ref:`plugin_permission_allowed` plugin hook.
+
+If neither ``metadata.json`` nor any of the plugins provide an answer to the permission query the ``default`` argument will be returned.

 Changelog
 =========
 
+.. _v0_44:
+
+0.44 (2020-06-??)
+-----------------
+
+Authentication and permissions, writable canned queries, flash messages, new plugin hooks and more.
+
+Authentication
+~~~~~~~~~~~~~~
+
+Prior to this release the Datasette ecosystem has treated authentication as exclusively the realm of plugins, most notably through `datasette-auth-github `__.
+
+0.44 introduces :ref:`authentication` as core Datasette concepts (`#699 `__). This makes it easier for different plugins can share responsibility for authenticating requests - you might have one plugin that handles user accounts and another one that allows automated access via API keys, for example.
+
+You'll need to install plugins if you want full user accounts, but default Datasette can now authenticate a single root user with the new ``--root`` command-line option, which outputs a one-time use URL to :ref:`authenticate as a root actor ` (`#784 `__)::
+
+    $ datasette fixtures.db --root
+    http://127.0.0.1:8001/-/auth-token?token=5b632f8cd44b868df625f5a6e2185d88eea5b22237fd3cc8773f107cc4fd6477
+    INFO:     Started server process [14973]
+    INFO:     Waiting for application startup.
+    INFO:     Application startup complete.
+    INFO:     Uvicorn running on http://127.0.0.1:8001 (Press CTRL+C to quit)
+
+Plugins can implement new ways of authenticating users using the new :ref:`plugin_actor_from_request` hook.
+
+Permissions
+~~~~~~~~~~~
+
+Datasette also now has a built-in concept of :ref:`authentication_permissions`. The permissions system answers the following question:
+
+    Is this **actor** allowed to perform this **action**, optionally against this particular **resource**?
+
+You can use the new ``"allow"`` block syntax in ``metadata.json`` (or ``metadata.yaml``) to set required permissions at the instance, database, table or canned query level. For example, to restrict access to the ``fixtures.db`` database to the ``"root"`` user:
+
+.. code-block:: json
+
+    {
+        "databases": {
+            "fixtures": {
+                "allow": {
+                    "id" "root"
+                }
+            }
+        }
+    }
+
+See :ref:`authentication_permissions_allow` for more details.
+
+Plugins can implement their own custom permission checks using the new :ref:`plugin_permission_allowed` hook.
+
+A new debug page at ``/-/permissions`` shows recent permission checks, to help administrators and plugin authors understand exactly what checks are being performed. This tool defaults to only being available to the root user, but can be exposed to other users by plugins that respond to the ``permissions-debug`` permission. (`#788 `__)
+
+Writable canned queries
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Datasette's :ref:`canned_queries` feature lets you define SQL queries in ``metadata.json`` which can then be executed by users visiting a specific URL. https://latest.datasette.io/fixtures/neighborhood_search for example.
+
+Canned queries were previously restricted to ``SELECT``, but Datasette 0.44 introduces the ability for canned queries to execute ``INSERT`` or ``UPDATE`` queries as well, using the new ``"write": true`` property (`#800 `__):
+
+.. code-block:: json
+
+    {
+        "databases": {
+            "dogs": {
+                "queries": {
+                    "add_name": {
+                        "sql": "INSERT INTO names (name) VALUES (:name)",
+                        "write": true
+                    }
+                }
+            }
+        }
+    }
+
+See :ref:`canned_queries_writable` for more details.
+
+Flash messages
+~~~~~~~~~~~~~~
+
+Writable canned queries needed a mechanism to let the user know that the query has been successfully executed. The new flash messaging system (`#790 `__) allows messages to persist in signed cookies which are then displayed to the user on the next page that they visit. Plugins can use this mechanism to display their own messages, see :ref:`datasette_add_message` for details.
+
+You can try out the new messages using the ``/-/messages`` debug tool, for example at https://latest.datasette.io/-/messages
+
+Signed values and secrets
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Both flash messages and user authentication needed a way to sign values and set signed cookies. Two new methods are now available for plugins to take advantage of this mechanism: :ref:`datasette_sign` and :ref:`datasette_unsign`.
+
+Datasette will generate a secret automatically when it starts up, but to avoid resetting the secret (and hence invalidating any cookies) every time the server restarts you should set your own secret. You can pass a secret to Datasette using the new ``--secret`` option or with a ``DATASETTE_SECRET`` environment variable. See :ref:`config_secret` for more details.
+
+Plugins can now sign value and verify their signatures using the :ref:`datasette.sign() ` and :ref:`datasette.unsign() ` methods.
+
+CSRF protection
+~~~~~~~~~~~~~~~
+
+Since writable canned queries are built using POST forms, Datasette now ships with :ref:`internals_csrf` (`#798 `__). This applies automatically to any POST request, which means plugins need to include a ``csrftoken`` in any POST forms that they render. They can do that like so:
+
+.. code-block:: html
+
+    
+
+register_routes() plugin hooks
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Plugins can now register new views and routes via the :ref:`plugin_register_routes` plugin hook (`#819 `__). View functions can be defined that accept any of the current ``datasette`` object, the current ``request``, or the ASGI ``scope``, ``send`` and ``receive`` objects.
+
+Smaller changes
+~~~~~~~~~~~~~~~
+
+- New internals documentation for :ref:`internals_request` and :ref:`internals_response`. (`#706 `__)
+- ``request.url`` now respects the ``force_https_urls`` config setting. closes (`#781 `__)
+- ``request.args.getlist()`` returns ``[]`` if missing. Removed ``request.raw_args`` entirely. (`#774 `__)
+- New :ref:`datasette.get_database() ` method.
+- Added ``_`` prefix to many private, undocumented methods of the Datasette class. (`#576 `__)
+- Removed the ``db.get_outbound_foreign_keys()`` method which duplicated the behaviour of ``db.foreign_keys_for_table()``.
+- New :ref:`await datasette.permission_allowed() ` method.
+- ``/-/actor`` debugging endpoint for viewing the currently authenticated actor.
+- New ``request.cookies`` property.
+- ``/-/plugins`` endpoint now shows a list of hooks implemented by each plugin, e.g. https://latest.datasette.io/-/plugins?all=1
+- ``request.post_vars()`` method no longer discards empty values.
+- New "params" canned query key for explicitly setting named parameters, see :ref:`canned_queries_named_parameters`. (`#797 `__)
+- ``request.args`` is now a :ref:`MultiParams ` object.
+- Fixed a bug with the ``datasette plugins`` command. (`#802 `__)
+- Nicer pattern for using ``make_app_client()`` in tests. (`#395 `__)
+- New ``request.actor`` property.
+- Fixed broken CSS on nested 404 pages. (`#777 `__)
+- New ``request.url_vars`` property. (`#822 `__)
+- Fixed a bug with the ``python tests/fixtures.py`` command for outputting Datasette's testing fixtures database and plugins. (`#804 `__)
+
+The road to Datasette 1.0
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+I've assembled a `milestone for Datasette 1.0 `__. The focus of the 1.0 release will be the following:
+
+- Signify confidence in the quality/stability of Datasette
+- Give plugin authors confidence that their plugins will work for the whole 1.x release cycle
+- Provide the same confidence to developers building against Datasette JSON APIs
+
+If you have thoughts about what you would like to see for Datasette 1.0 you can join `the conversation on issue #519 `__.

+------------------------
+
+``ds_actor`` cookies can optionally include a signed expiry timestamp, after which the cookies will no longer be valid. Authentication plugins may chose to use this mechanism to limit the lifetime of the cookie. For example, if a plugin implements single-sign-on against another source it may decide to set short-lived cookies so that if the user is removed from the SSO system their existing Datasette cookies will stop working shortly afterwards.
+
+To include an expiry, add a ``"e"`` key to the cookie value containing a `base62-encoded integer `__ representing the timestamp when the cookie should expire. For example, here's how to set a cookie that expires after 24 hours:
+
+.. code-block:: python
+
+    import time
+    import baseconv
+
+    expires_at = int(time.time()) + (24 * 60 * 60)
+
+    response = Response.redirect("/")
+    response.set_cookie("ds_actor", datasette.sign({
+        "a": {
+            "id": "cleopaws"
+        },
+        "e": baseconv.base62.encode(expires_at),
+    }, "actor"))
+
+The resulting cookie will encode data that looks something like this:
+
+.. code-block:: json
+
+    {
+        "a": {
+            "id": "cleopaws"
+        },
+        "e": "1jjSji"
+    }

+------------------------------------
+
+The :ref:`cli_publish` and :ref:`cli_package` commands both generate a secret for you automatically when Datasette is deployed.
+
+This means that every time you deploy a new version of a Datasette project, a new secret will be generated. This will cause signed cookies to become inalid on every fresh deploy.
+
+You can fix this by creating a secret that will be used for multiple deploys and passing it using the ``--secret`` option::

 Datasette will generate a secret automatically when it starts up, but to avoid resetting the secret (and hence invalidating any cookies) every time the server restarts you should set your own secret. You can pass a secret to Datasette using the new ``--secret`` option or with a ``DATASETTE_SECRET`` environment variable. See :ref:`config_secret` for more details.
 
+You can also set a secret when you deploy Datasette using ``datasette publish`` or ``datasette package`` - see :ref:`config_publish_secrets`.

+This hook fires when the Datasette application server first starts up. You can implement a regular function, for example to validate required plugin configuration:
+
+.. code-block:: python
+
+    @hookimpl
+    def startup(datasette):
+        config = datasette.plugin_config("my-plugin") or {}

+
+Or you can return an async function which will be awaited on startup. Use this option if you need to make any database queries:
+
+    @hookimpl
+    def startup(datasette):
+        async def inner():
+            db = datasette.get_database()

+                """, block=True)
+        return inner

+.. _plugin_hooks:
+
+Plugin hooks
+============
+
+When you implement a plugin hook you can accept any or all of the parameters that are documented as being passed to that hook. For example, you can implement a ``render_cell`` plugin hook like this even though the hook definition defines more parameters than just ``value`` and ``column``:
+
+.. code-block:: python
+
+    @hookimpl
+    def render_cell(value, column):
+        if column == "stars":
+            return "*" * int(value)
+
+The full list of available plugin hooks is as follows.
+
+.. _plugin_hook_prepare_connection:
+
+prepare_connection(conn, database, datasette)
+---------------------------------------------
+
+``conn`` - sqlite3 connection object
+    The connection that is being opened
+
+``database`` - string
+    The name of the database
+
+``datasette`` - :ref:`internals_datasette`
+    You can use this to access plugin configuration options via ``datasette.plugin_config(your_plugin_name)``
+
+This hook is called when a new SQLite database connection is created. You can
+use it to `register custom SQL functions `_,
+aggregates and collations. For example:
+
+.. code-block:: python
+
+    from datasette import hookimpl
+    import random
+
+    @hookimpl
+    def prepare_connection(conn):
+        conn.create_function('random_integer', 2, random.randint)
+
+This registers a SQL function called ``random_integer`` which takes two
+arguments and can be called like this::
+
+    select random_integer(1, 10);
+
+Examples: `datasette-jellyfish `_, `datasette-jq `_, `datasette-haversine `__, `datasette-rure `__
+
+.. _plugin_hook_prepare_jinja2_environment:
+
+prepare_jinja2_environment(env)
+-------------------------------
+
+``env`` - jinja2 Environment
+    The template environment that is being prepared
+
+This hook is called with the Jinja2 environment that is used to evaluate
+Datasette HTML templates. You can use it to do things like `register custom
+template filters `_, for
+example:
+
+.. code-block:: python
+
+    from datasette import hookimpl
+
+    @hookimpl
+    def prepare_jinja2_environment(env):
+        env.filters['uppercase'] = lambda u: u.upper()
+
+You can now use this filter in your custom templates like so::
+
+    Table name: {{ table|uppercase }}
+
+.. _plugin_hook_extra_css_urls:
+
+extra_css_urls(template, database, table, datasette)
+----------------------------------------------------
+
+``template`` - string
+    The template that is being rendered, e.g. ``database.html``
+
+``database`` - string or None
+    The name of the database
+
+``table`` - string or None
+    The name of the table
+
+``datasette`` - :ref:`internals_datasette`
+    You can use this to access plugin configuration options via ``datasette.plugin_config(your_plugin_name)``
+
+Return a list of extra CSS URLs that should be included on the page. These can
+take advantage of the CSS class hooks described in :ref:`customization`.
+
+This can be a list of URLs:
+
+.. code-block:: python
+
+    from datasette import hookimpl
+
+    @hookimpl
+    def extra_css_urls():
+        return [
+            'https://stackpath.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css'
+        ]
+
+Or a list of dictionaries defining both a URL and an
+`SRI hash `_:
+
+.. code-block:: python
+
+    from datasette import hookimpl
+
+    @hookimpl
+    def extra_css_urls():
+        return [{
+            'url': 'https://stackpath.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css',
+            'sri': 'sha384-9gVQ4dYFwwWSjIDZnLEWnxCjeSWFphJiwGPXr1jddIhOegiu1FwO5qRGvFXOdJZ4',
+        }]
+
+Examples: `datasette-cluster-map `_, `datasette-vega `_
+
+.. _plugin_hook_extra_js_urls:
+
+extra_js_urls(template, database, table, datasette)
+---------------------------------------------------
+
+Same arguments as ``extra_css_urls``.
+
+This works in the same way as ``extra_css_urls()`` but for JavaScript. You can
+return either a list of URLs or a list of dictionaries:
+
+.. code-block:: python
+
+    from datasette import hookimpl
+
+    @hookimpl
+    def extra_js_urls():
+        return [{
+            'url': 'https://code.jquery.com/jquery-3.3.1.slim.min.js',
+            'sri': 'sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo',
+        }]
+
+You can also return URLs to files from your plugin's ``static/`` directory, if
+you have one:
+
+.. code-block:: python
+
+    from datasette import hookimpl
+
+    @hookimpl
+    def extra_js_urls():
+        return [
+            '/-/static-plugins/your-plugin/app.js'
+        ]
+
+Examples: `datasette-cluster-map `_, `datasette-vega `_
+
+.. _plugin_hook_publish_subcommand:
+
+publish_subcommand(publish)
+---------------------------
+
+``publish`` - Click publish command group
+    The Click command group for the ``datasette publish`` subcommand
+
+This hook allows you to create new providers for the ``datasette publish``
+command. Datasette uses this hook internally to implement the default ``now``
+and ``heroku`` subcommands, so you can read
+`their source `_
+to see examples of this hook in action.
+
+Let's say you want to build a plugin that adds a ``datasette publish my_hosting_provider --api_key=xxx mydatabase.db`` publish command. Your implementation would start like this:
+
+.. code-block:: python
+
+    from datasette import hookimpl
+    from datasette.publish.common import add_common_publish_arguments_and_options
+    import click
+
+
+    @hookimpl
+    def publish_subcommand(publish):
+        @publish.command()
+        @add_common_publish_arguments_and_options
+        @click.option(
+            "-k",
+            "--api_key",
+            help="API key for talking to my hosting provider",
+        )
+        def my_hosting_provider(
+            files,
+            metadata,
+            extra_options,
+            branch,
+            template_dir,
+            plugins_dir,
+            static,
+            install,
+            plugin_secret,
+            version_note,
+            secret,
+            title,
+            license,
+            license_url,
+            source,
+            source_url,
+            about,
+            about_url,
+            api_key,
+        ):
+            # Your implementation goes here
+
+Examples: `datasette-publish-fly `_, `datasette-publish-now `_
+
+.. _plugin_hook_render_cell:
+
+render_cell(value, column, table, database, datasette)
+------------------------------------------------------
+
+Lets you customize the display of values within table cells in the HTML table view.
+
+``value`` - string, integer or None
+    The value that was loaded from the database
+
+``column`` - string
+    The name of the column being rendered
+
+``table`` - string or None
+    The name of the table - or ``None`` if this is a custom SQL query
+
+``database`` - string
+    The name of the database
+
+``datasette`` - :ref:`internals_datasette`
+    You can use this to access plugin configuration options via ``datasette.plugin_config(your_plugin_name)``
+
+If your hook returns ``None``, it will be ignored. Use this to indicate that your hook is not able to custom render this particular value.
+
+If the hook returns a string, that string will be rendered in the table cell.
+
+If you want to return HTML markup you can do so by returning a ``jinja2.Markup`` object.
+
+Datasette will loop through all available ``render_cell`` hooks and display the value returned by the first one that does not return ``None``.
+
+Here is an example of a custom ``render_cell()`` plugin which looks for values that are a JSON string matching the following format::
+
+    {"href": "https://www.example.com/", "label": "Name"}
+
+If the value matches that pattern, the plugin returns an HTML link element:
+
+.. code-block:: python
+
+    from datasette import hookimpl
+    import jinja2
+    import json
+
+
+    @hookimpl
+    def render_cell(value):
+        # Render {"href": "...", "label": "..."} as link
+        if not isinstance(value, str):
+            return None
+        stripped = value.strip()
+        if not stripped.startswith("{") and stripped.endswith("}"):
+            return None
+        try:
+            data = json.loads(value)
+        except ValueError:
+            return None
+        if not isinstance(data, dict):
+            return None
+        if set(data.keys()) != {"href", "label"}:
+            return None
+        href = data["href"]
+        if not (
+            href.startswith("/") or href.startswith("http://")
+            or href.startswith("https://")
+        ):
+            return None
+        return jinja2.Markup('{label}'.format(
+            href=jinja2.escape(data["href"]),
+            label=jinja2.escape(data["label"] or "") or " "
+        ))
+
+Examples: `datasette-render-binary `_, `datasette-render-markdown `_
+
+.. _plugin_hook_extra_body_script:
+
+extra_body_script(template, database, table, view_name, datasette)
+------------------------------------------------------------------
+
+Extra JavaScript to be added to a ``")
     json_data = r.search(app_client.get(path).text).group(1)
     actual_data = json.loads(json_data)

+0.48 (2020-08-16)
+-----------------
+
+- Datasette documentation now lives at `docs.datasette.io `__.
+- ``db.is_mutable`` property is now documented and tested, see :ref:`internals_database_introspection`.
+- The ``extra_template_vars``, ``extra_css_urls``, ``extra_js_urls`` and ``extra_body_script`` plugin hooks now all accept the same arguments. See :ref:`plugin_hook_extra_template_vars` for details. (`#939 `__)
+- Those hooks now accept a new ``columns`` argument detailing the table columns that will be rendered on that page. (`#938 `__)
+- Fixed bug where plugins calling ``db.execute_write_fn()`` could hang Datasette if the connection failed. (`#935 `__)
+- Fixed bug with the ``?_nl=on`` output option and binary data. (`#914 `__)

+----------------------
+
+``cli`` - the root Datasette `Click command group `__
+    Use this to register additional CLI commands
+
+Register additional CLI commands that can be run using ``datsette yourcommand ...``. This provides a mechanism by which plugins can add new CLI commands to Datasette.
+
+This example registers a new ``datasette verify file1.db file2.db`` command that checks if the provided file paths are valid SQLite databases:
+
+.. code-block:: python
+
+    from datasette import hookimpl
+    import click
+    import sqlite3
+
+    @hookimpl
+    def register_commands(cli):
+        @cli.command()
+        @click.argument("files", type=click.Path(exists=True), nargs=-1)
+        def verify(files):
+            "Verify that files can be opened by Datasette"
+            for file in files:
+                conn = sqlite3.connect(str(file))
+                try:
+                    conn.execute("select * from sqlite_master")
+                except sqlite3.DatabaseError:
+                    raise click.ClickException("Invalid database: {}".format(file))
+
+The new command can then be executed like so::
+
+    datasette verify fixtures.db
+
+Help text (from the docstring for the function plus any defined Click arguments or options) will become available using::
+
+    datasette verify --help
+
+Plugins can register multiple commands by making multiple calls to the ``@cli.command()`` decorator.Consult the `Click documentation `__ for full details on how to build a CLI command, including how to define arguments and options.
+
+Note that ``register_commands()`` plugins cannot used with the :ref:`--plugins-dir mechanism ` - they need to be installed into the same virtual environment as Datasette using ``pip install``. Provided it has a ``setup.py`` file (see :ref:`writing_plugins_packaging`) you can run ``pip install`` directly against the directory in which you are developing your plugin like so::
+
+    pip install -e path/to/my/datasette-plugin

+- Columns can now have associated metadata descriptions in ``metadata.json``, see :ref:`metadata_column_descriptions`. (:issue:`942`)
+- New :ref:`register_commands() ` plugin hook allows plugins to register additional Datasette CLI commands, e.g. ``datasette mycommand file.db``. (:issue:`1449`)
+- Adding ``?_facet_size=max`` to a table page now shows the number of unique values in each facet. (:issue:`1423`)
+- Code that figures out which named parameters a SQL query takes in order to display form fields for them is no longer confused by strings that contain colon characters. (:issue:`1421`)
+- Renamed ``--help-config`` option to ``--help-settings``. (:issue:`1431`)
+- ``datasette.databases`` property is now a documented API. (:issue:`1443`)
+- Datasette base template now wraps everything other than the ``
    `` in a ``
    `` element, to help with advanced CSS customization. (:issue:`1446`)

-If a table has a corresponding FTS table set up using the ``content=`` argument to ``CREATE VIRTUAL TABLE`` shown above, Datasette will detect it automatically and add a search interface to the table page for that table.
+If a table has a corresponding FTS table set up using the ``content=`` argument to ``CREATE VIRTUAL TABLE`` shown below, Datasette will detect it automatically and add a search interface to the table page for that table.
 
 You can also manually configure which table should be used for full-text search using query string parameters or :ref:`metadata`. You can set the associated FTS table for a specific table and you can also set one for a view - if you do that, the page for that SQL view will offer a search option.

+-----------------
 
 - Columns can now have associated metadata descriptions in ``metadata.json``, see :ref:`metadata_column_descriptions`. (:issue:`942`)
 - New :ref:`register_commands() ` plugin hook allows plugins to register additional Datasette CLI commands, e.g. ``datasette mycommand file.db``. (:issue:`1449`)
 - Adding ``?_facet_size=max`` to a table page now shows the number of unique values in each facet. (:issue:`1423`)
+- Upgraded dependency `httpx 0.20 `__ - the undocumented ``allow_redirects=`` parameter to :ref:`internals_datasette_client` is now ``follow_redirects=``, and defalts to ``False`` where it previously defaulted to ``True``. (:issue:`1488`)
+- The ``--cors`` option now causes Datasette to return the ``Access-Control-Allow-Headers: Authorization`` header, in addition to ``Access-Control-Allow-Origin: *``. (`#1467 `__)
 - Code that figures out which named parameters a SQL query takes in order to display form fields for them is no longer confused by strings that contain colon characters. (:issue:`1421`)
 - Renamed ``--help-config`` option to ``--help-settings``. (:issue:`1431`)
 - ``datasette.databases`` property is now a documented API. (:issue:`1443`)

 - New ``--cpu`` option for :ref:`datasette publish cloudrun `. (:issue:`1420`)
 - If `Rich `__ is installed in the same virtual environment as Datasette, it will be used to provide enhanced display of error tracebacks on the console. (:issue:`1416`)
 - ``datasette.utils`` :ref:`internals_utils_parse_metadata` function, used by the new `datasette-remote-metadata plugin `__, is now a documented API. (:issue:`1405`)

 SQLite string escaping rules will be applied to values passed using named parameters - they will be wrapped in quotes and their content will be correctly escaped.
 
+Values from named parameters are treated as SQLite strings. If you need to perform numeric comparisons on them you should cast them to an integer or float first using ``cast(:name as integer)`` or ``cast(:name as real)``, for example:
+
+.. code-block:: sql
+
+    select * from Street_Tree_List
+    where latitude > cast(:min_latitude as real)
+    and latitude < cast(:max_latitude as real)
+
 Datasette disallows custom SQL queries containing the string PRAGMA (with a small number `of exceptions `__) as SQLite pragma statements can be used to change database settings at runtime. If you need to include the string "pragma" in a query you can do so safely using a named parameter.

 Changelog
 =========
 
+.. _v0_59_2:
+
+0.59.2 (2021-11-13)
+-------------------
+
+- Column names with a leading underscore now work correctly when used as a facet. (:issue:`1506`)
+- Applying ``?_nocol=`` to a column no longer removes that column from the filtering interface. (:issue:`1503`)
+- Official Datasette Docker container now uses Debian Bullseye as the base image. (:issue:`1497`)
+- Datasette is four years old today! Here's the `original release announcement `__ from 2017.
+
 .. _v0_59_1:
 
 0.59.1 (2021-10-24)

+
+To deploy to [Fly](https://fly.io/) first create an application there by running:
+
+    flyctl apps create --name datasette-apache-proxy-demo
+
+You will need a different name, since I have already taken that one.

+This uses `fly.toml` in this directory, which hard-codes the `datasette-apache-proxy-demo` name - so you would need to edit that file to match your application name before running this.

 Changelog
 =========
 
+.. _v0_59_3:
+
+0.59.3 (2021-11-20)
+-------------------
+
+- Fixed numerous bugs when running Datasette :ref:`behind a proxy ` with a prefix URL path using the :ref:`setting_base_url` setting. A live demo of this mode is now available at `datasette-apache-proxy-demo.datasette.io/prefix/ `__. (:issue:`1519`, :issue:`838`)
+- ``?column__arraycontains=`` and ``?column__arraynotcontains=`` table parameters now also work against SQL views. (:issue:`448`)
+- ``?_facet_array=column`` no longer returns incorrect counts if columns contain the same value more than once.
+
 .. _v0_59_2:
 
 0.59.2 (2021-11-13)

Subject: [PATCH 1274/2321] filters_from_request plugin hook, now used in
 TableView

- New `filters_from_request` plugin hook, closes #473
- Used it to extract the logic from TableView that handles `_search` and
`_through` and `_where` - refs #1518

Also needed for this plugin work: https://github.com/simonw/datasette-leaflet-freedraw/issues/7

+
+filters_from_request(request, database, table, datasette)
+---------------------------------------------------------
+
+``request`` - object
+    The current HTTP :ref:`internals_request`.
+
+``database`` - string
+    The name of the database.
+
+``table`` - string
+    The name of the table.
+
+``datasette`` - :ref:`internals_datasette`
+    You can use this to access plugin configuration options via ``datasette.plugin_config(your_plugin_name)``, or to execute SQL queries.
+
+This hook runs on the :ref:`table ` page, and can influence the ``where`` clause of the SQL query used to populate that page, based on query string arguments on the incoming request.
+
+The hook should return an instance of ``datasette.filters.FilterArguments`` which has one required and three optional arguments:
+
+.. code-block:: python
+
+    return FilterArguments(
+        where_clauses=["id > :max_id"],
+        params={"max_id": 5},
+        human_descriptions=["max_id is greater than 5"],
+        extra_context={}
+    )
+
+The arguments to the ``FilterArguments`` class constructor are as follows:
+
+``where_clauses`` - list of strings, required
+    A list of SQL fragments that will be inserted into the SQL query, joined by the ``and`` operator. These can include ``:named`` parameters which will be populated using data in ``params``.
+``params`` - dictionary, optional
+    Additional keyword arguments to be used when the query is executed. These should match any ``:arguments`` in the where clauses.
+``human_descriptions`` - list of strings, optional
+    These strings will be included in the human-readable description at the top of the page and the page ````.
+``extra_context`` - dictionary, optional
+    Additional context variables that should be made available to the ``table.html`` template when it is rendered.
+
+This example plugin causes 0 results to be returned if ``?_nothing=1`` is added to the URL:
+
+.. code-block:: python
+
+    from datasette import hookimpl
+    from datasette.filters import FilterArguments
+
+    @hookimpl
+    def filters_from_request(self, request):

 Changelog
 =========
 
+.. _v0_60a0:
+
+0.60a0 (2021-12-17)
+-------------------
+
+- New plugin hook: :ref:`plugin_hook_filters_from_request`, which runs on the table page and can be used to support new custom query string parameters that modify the SQL query. (:issue:`473`)
+- The number of unique values in a facet is now always displayed. Previously it was only displayed if the user specified ``?_facet_size=max``. (:issue:`1556`)
+- Fixed bug where ``?_facet_array=tags&_facet=tags`` would only display one of the two selected facets. (:issue:`625`)
+- Facets of type ``date`` or ``array`` can now be configured in ``metadata.json``, see :ref:`facets_metadata`. Thanks, David Larlet. (:issue:`1552`)
+- New ``?_nosuggest=1`` parameter for table views, which disables facet suggestion. (:issue:`1557`)
+- Label columns detected for foreign keys are now case-insensitive, so ``Name`` or ``TITLE`` will be detected in the same way as ``name`` or ``title``. (:issue:`1544`)
+- The query string variables exposed by ``request.args`` will now include blank strings for arguments such as ``foo`` in ``?foo=&bar=1`` rather than ignoring those parameters entirely. (:issue:`1551`)

 If you pass ``block=True`` this behaviour changes: the method will block until the write operation has completed, and the return value will be the return from calling ``conn.execute(...)`` using the underlying ``sqlite3`` Python library.

 Changelog
 =========
 
+.. _v0_60a1:
+
+0.60a1 (2021-12-19)
+-------------------
+
+- Database write connections now execute the :ref:`plugin_hook_prepare_connection` plugin hook. (:issue:`1564`)
+- The ``Datasette()`` constructor no longer requires the ``files=`` argument, and is now documented at :ref:`internals_datasette`. (:issue:`1563`)
+- The tracing feature now traces write queries, not just read queries. (:issue:`1568`)
+- Added two methods for writing to the database: :ref:`database_execute_write_script` and :ref:`database_execute_write_many`. (:issue:`1570`)
+- Made several performance improvements to the database schema introspection code that runs when Datasette first starts up. (:issue:`1555`)
+- Fixed bug where writable canned queries could not be used with custom templates.  (:issue:`1547`)

+- New plugin hook: :ref:`plugin_hook_filters_from_request`, which runs on the table page and can be used to support new custom query string parameters that modify the SQL query. (:issue:`473`)
+- Added two additional methods for writing to the database: :ref:`database_execute_write_script` and :ref:`database_execute_write_many`. (:issue:`1570`)
+- The :ref:`db.execute_write() <database_execute_write>` internal method now defaults to blocking until the write operation has completed. Previously it defaulted to queuing the write and then continuing to run code while the write was in the queue. (:issue:`1579`)
 - Database write connections now execute the :ref:`plugin_hook_prepare_connection` plugin hook. (:issue:`1564`)
 - The ``Datasette()`` constructor no longer requires the ``files=`` argument, and is now documented at :ref:`internals_datasette`. (:issue:`1563`)
 - The tracing feature now traces write queries, not just read queries. (:issue:`1568`)
-- Added two methods for writing to the database: :ref:`database_execute_write_script` and :ref:`database_execute_write_many`. (:issue:`1570`)
-- Made several performance improvements to the database schema introspection code that runs when Datasette first starts up. (:issue:`1555`)
-- Fixed bug where writable canned queries could not be used with custom templates.  (:issue:`1547`)
+- The query string variables exposed by ``request.args`` will now include blank strings for arguments such as ``foo`` in ``?foo=&bar=1`` rather than ignoring those parameters entirely. (:issue:`1551`)

-0.60a0 (2021-12-17)
--------------------
-
-- New plugin hook: :ref:`plugin_hook_filters_from_request`, which runs on the table page and can be used to support new custom query string parameters that modify the SQL query. (:issue:`473`)
 - The number of unique values in a facet is now always displayed. Previously it was only displayed if the user specified ``?_facet_size=max``. (:issue:`1556`)
-- Fixed bug where ``?_facet_array=tags&_facet=tags`` would only display one of the two selected facets. (:issue:`625`)
 - Facets of type ``date`` or ``array`` can now be configured in ``metadata.json``, see :ref:`facets_metadata`. Thanks, David Larlet. (:issue:`1552`)
 - New ``?_nosuggest=1`` parameter for table views, which disables facet suggestion. (:issue:`1557`)
+- Fixed bug where ``?_facet_array=tags&_facet=tags`` would only display one of the two selected facets. (:issue:`625`)
+
+Other small fixes
+~~~~~~~~~~~~~~~~~
+
+- Made several performance improvements to the database schema introspection code that runs when Datasette first starts up. (:issue:`1555`)
 - Label columns detected for foreign keys are now case-insensitive, so ``Name`` or ``TITLE`` will be detected in the same way as ``name`` or ``title``. (:issue:`1544`)
-- The query string variables exposed by ``request.args`` will now include blank strings for arguments such as ``foo`` in ``?foo=&bar=1`` rather than ignoring those parameters entirely. (:issue:`1551`)
+- Upgraded Pluggy dependency to 1.0. (:issue:`1575`)
+- Now using `Plausible analytics <https://plausible.io/>`__ for the Datasette documentation.
+- ``explain query plan`` is now allowed with varying amounts of whitespace in the query. (:issue:`1588`)
+- New :ref:`cli_reference` page showing the output of ``--help`` for each of the ``datasette`` sub-commands. This lead to several small improvements to the help copy. (:issue:`1594`)
+- Fixed bug where writable canned queries could not be used with custom templates.  (:issue:`1547`)
+- Improved fix for a bug where columns with a underscore prefix could result in unnecessary hidden form fields. (:issue:`1527`)

 Named parameters that start with an underscore are special: they can be used to automatically add values created by Datasette that are not contained in the incoming form fields or query string.
 
+These magic parameters are only supported for canned queries: to avoid security issues (such as queries that extract the user's private cookies) they are not available to SQL that is executed by the user as a custom SQL query.
+
 Available magic parameters are:
 
 ``_actor_*`` - e.g. ``_actor_id``, ``_actor_name``

 This function accepts a string containing either JSON or YAML, expected to be of the format described in :ref:`metadata`. It returns a nested Python dictionary representing the parsed data from that string.
 
 If the metadata cannot be parsed as either JSON or YAML the function will raise a ``utils.BadMetadataError`` exception.

+
+datasette.tracer
+================
+
+Running Datasette with ``--setting trace_debug 1`` enables trace debug output, which can then be viewed by adding ``?_trace=1`` to the query string for any page.
+
+You can see an example of this at the bottom of `latest.datasette.io/fixtures/facetable?_trace=1 <https://latest.datasette.io/fixtures/facetable?_trace=1>`__. The JSON output shows full details of every SQL query that was executed to generate the page.
+
+The `datasette-pretty-traces <https://datasette.io/plugins/datasette-pretty-traces>`__ plugin can be installed to provide a more readable display of this information. You can see `a demo of that here <https://latest-with-plugins.datasette.io/github/commits?_trace=1>`__.
+
+You can add your own custom traces to the JSON output using the ``trace()`` context manager. This takes a string that identifies the type of trace being recorded, and records any keyword arguments as additional JSON keys on the resulting trace object.
+
+The start and end time, duration and a traceback of where the trace was executed will be automatically attached to the JSON object.
+
+This example uses trace to record the start, end and duration of any HTTP GET requests made using the function:
+
+.. code-block:: python
+
+    from datasette.tracer import trace
+    import httpx
+
+    async def fetch_url(url):
+        with trace("fetch-url", url=url):
+            async with httpx.AsyncClient() as client:
+                return await client.get(url)
+
+.. _internals_tracer_trace_child_tasks
+
+Tracing child tasks
+-------------------
+
+If your code uses a mechanism such as ``asyncio.gather()`` to execute code in additional tasks you may find that some of the traces are missing from the display.
+
+You can use the ``trace_child_tasks()`` context manager to ensure these child tasks are correctly handled.
+
+.. code-block:: python
+
+    from datasette import tracer
+
+    with tracer.trace_child_tasks():
+        results = await asyncio.gather(
+            # ... async tasks here
+        )
+
+This example uses the :ref:`register_routes() <plugin_register_routes>` plugin hook to add a page at ``/parallel-queries`` which executes two SQL queries in parallel using ``asyncio.gather()`` and returns their results.
+
+.. code-block:: python
+
+    from datasette import hookimpl
+    from datasette import tracer
+
+    @hookimpl
+    def register_routes():
+
+        async def parallel_queries(datasette):
+            db = datasette.get_database()
+            with tracer.trace_child_tasks():
+                one, two = await asyncio.gather(
+                    db.execute("select 1"),
+                    db.execute("select 2"),
+                )
+            return Response.json({"one": one.single_value(), "two": two.single_value()})
+
+        return [
+            (r"/parallel-queries$", parallel_queries),
+        ]
+
+
+Adding ``?_trace=1`` will show that the trace covers both of those child tasks.

Read more about this function in `The “await me maybe” pattern for Python asyncio <https://simonwillison.net/2020/Sep/2/await-me-maybe/>`__.

 Changelog
 =========
 
+.. _v0_60.2:
+
+0.60.2 (2022-02-07)
+-------------------
+
+- Fixed a bug where Datasette would open the same file twice with two different database names if you ran ``datasette file.db file.db``. (:issue:`1632`)
+
+.. _v0_60.1:
+
+0.60.1 (2022-01-20)
+-------------------
+
+- Fixed a bug where installation on Python 3.6 stopped working due to a change to an underlying dependency. This release can now be installed on Python 3.6, but is the last release of Datasette that will support anything less than Python 3.7. (:issue:`1609`)

This reverts commit 5bfd001b55357106dba090c83a1c88912a004665.

No need for this on the main branch because it doesn't support Python 3.6 any more.

+Dash encoding
+-------------
+
+Datasette uses a custom encoding scheme in some places, called **dash encoding**. This is primarily used for table names and row primary keys, to avoid any confusion between ``/`` characters in those values and the Datasette URLs that reference them.
+
+Dash encoding uses the same algorithm as `URL percent-encoding <https://developer.mozilla.org/en-US/docs/Glossary/percent-encoding>`__, but with the ``-`` hyphen character used in place of ``%``.
+
+Any character other than ``ABCDEFGHIJKLMNOPQRSTUVWXYZ abcdefghijklmnopqrstuvwxyz 0123456789_`` will be replaced by the numeric equivalent preceded by a hyphen. For example:
+
+- ``/`` becomes ``-2F``
+- ``.`` becomes ``-2E``
+- ``%`` becomes ``-25``
+- ``-`` becomes ``-2D``
+- Space character becomes ``-20``
+- ``polls/2022.primary`` becomes ``polls-2F2022-2Eprimary``

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+`swillison+datasette-code-of-conduct@gmail.com`.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.

 You can also change the cache timeout on a per-request basis using the ``?_ttl=10`` query string parameter. This can be useful when you are working with the Datasette JSON API - you may decide that a specific query can be cached for a longer time, or maybe you need to set ``?_ttl=0`` for some requests for example if you are running a SQL ``order by random()`` query.
 
-Hashed URL mode
----------------
+datasette-hashed-urls
+---------------------
 
-When you open a database file in immutable mode using the ``-i`` option, Datasette calculates a SHA-256 hash of the contents of that file on startup. This content hash can then optionally be used to create URLs that are guaranteed to change if the contents of the file changes in the future. This results in URLs that can then be cached indefinitely by both browsers and caching proxies - an enormous potential performance optimization.
+If you open a database file in immutable mode using the ``-i`` option, you can be assured that the content of that database will not change for the lifetime of the Datasette server.
 
-You can enable these hashed URLs in two ways: using the :ref:`setting_hash_urls` configuration setting (which affects all requests to Datasette) or via the ``?_hash=1`` query string parameter (which only applies to the current request).
+The `datasette-hashed-urls plugin <https://datasette.io/plugins/datasette-hashed-urls>`__ implements an optimization where your database is served with part of the SHA-256 hash of the database contents baked into the URL.
 
-With hashed URLs enabled, any request to e.g. ``/mydatabase/mytable`` will 302 redirect to ``mydatabase-455fe3a/mytable``. The URL containing the hash will be served with a very long cache expire header - configured using :ref:`setting_default_cache_ttl_hashed` which defaults to 365 days.
+A database at ``/fixtures`` will instead be served at ``/fixtures-aa7318b``, and a year-long cache expiry header will be returned with those pages.
 
-Since these responses are cached for a long time, you may wish to build API clients against the non-hashed version of these URLs. These 302 redirects are served extremely quickly, so this should still be a performant way to work against the Datasette API.
+This will then be cached by both browsers and caching proxies such as Cloudflare or Fastly, providing a potentially significant performance boost.
 
-If you run Datasette behind an `HTTP/2 server push <https://en.wikipedia.org/wiki/HTTP/2_Server_Push>`__ aware proxy such as Cloudflare Datasette will serve the 302 redirects in such a way that the redirected page will be efficiently "pushed" to the browser as part of the response, without the browser needing to make a second HTTP request to fetch the redirected resource.
+To install the plugin, run the following::
+
+    datasette install datasette-hashed-urls
 
 .. note::
+    Prior to Datasette 0.61 hashed URL mode was a core Datasette feature, enabled using the ``hash_urls`` setting. This implementation has now been removed in favor of the ``datasette-hashed-urls`` plugin.
+
     Prior to Datasette 0.28 hashed URL mode was the default behaviour for Datasette, since all database files were assumed to be immutable and unchanging. From 0.28 onwards the default has been to treat database files as mutable unless explicitly configured otherwise.

+- Removed hashed URL mode from Datasette. The new ``datasette-hashed-urls`` plugin can be used to achieve the same result, see :ref:`performance_hashed_urls` for details. (:issue:`1661`)
+- Databases can now have a custom path within the Datasette instance that is indpendent of the database name, using the ``db.route`` property. (:issue:`1668`)
+- URLs within Datasette now use a different encoding scheme for tables or databases that include "special" characters outside of the range of ``a-zA-Z0-9_-``. This scheme is explained here: :ref:`internals_tilde_encoding`. (:issue:`1657`)
+- Table and row HTML pages now include a ``<link rel="alternate" type="application/json+datasette" href="...">`` element and return a ``Link: URL; rel="alternate"; type="application/json+datasette"`` HTTP header pointing to the JSON version of those pages. (:issue:`1533`)
+- ``Access-Control-Expose-Headers: Link`` is now added to the CORS headers, allowing remote JavaScript to access that header.
+- Canned queries are now shown at the top of the database page, directly below the SQL editor. Previously they were shown at the bottom, below the list of tables. (:issue:`1612`)
+- Datasette now has a default favicon. (:issue:`1603`)
+- ``sqlite_stat`` tables are now hidden by default. (:issue:`1587`)
+- SpatiaLite tables ``data_licenses``, ``KNN`` and ``KNN2`` are now hidden by default. (:issue:`1601`)
+- Python 3.6 is no longer supported. (:issue:`1577`)
+- Tests now run against Python 3.11-dev. (:issue:`1621`)
+- Fixed bug where :ref:`custom pages <custom_pages>` did not work on Windows. Thanks, Robert Christie. (:issue:`1545`)
+- SQL query tracing mechanism now works for queries executed in ``asyncio`` sub-tasks, such as those created by ``asyncio.gather()``. (:issue:`1576`)
+- :ref:`internals_tracer` mechanism is now documented.
+- Common Datasette symbols can now be imported directly from the top-level ``datasette`` package, see :ref:`internals_shortcuts`. Those symbols are ``Response``, ``Forbidden``, ``NotFound``, ``hookimpl``, ``actor_matches_allow``. (:issue:`957`)
+- ``/-/versions`` page now returns additional details for libraries used by SpatiaLite. (:issue:`1607`)
+- Documentation now links to the `Datasette Tutorials <https://datasette.io/tutorials>`__.
+- Datasette will now also look for SpatiaLite in ``/opt/homebrew`` - thanks, Dan Peterson. (`#1649 <https://github.com/simonw/datasette/pull/1649>`__)
+- Datasette is now covered by a `Code of Conduct <https://github.com/simonw/datasette/blob/main/CODE_OF_CONDUCT.md>`__. (:issue:`1654`)

 0.60.2 (2022-02-07)

 You can also change the cache timeout on a per-request basis using the ``?_ttl=10`` query string parameter. This can be useful when you are working with the Datasette JSON API - you may decide that a specific query can be cached for a longer time, or maybe you need to set ``?_ttl=0`` for some requests for example if you are running a SQL ``order by random()`` query.

+This method allows multiple permissions to be checked at onced. It raises a ``datasette.Forbidden`` exception if any of the checks are denied before one of them is explicitly granted.
+
+This is useful when you need to check multiple permissions at once. For example, an actor should be able to view a table if either one of the following checks returns ``True`` or not a single one of them returns ``False``:
+
+.. code-block:: python
+
+    await self.ds.ensure_permissions(
+        request.actor,
+        [
+            ("view-table", (database, table)),
+            ("view-database", database),
+            "view-instance",
+        ]
+    )
+
 .. _datasette_get_database:
 
 .get_database(name)

-0.61a0 (2022-03-19)
--------------------
+0.61 (2022-03-23)
+-----------------
 
+In preparation for Datasette 1.0, this release includes two potentially backwards-incompatible changes. Hashed URL mode has been moved to a separate plugin, and the way Datasette generates URLs to databases and tables with special characters in their name such as ``/`` and ``.`` has changed.
+
+Datasette also now requires Python 3.7 or higher.
+
+- URLs within Datasette now use a different encoding scheme for tables or databases that include "special" characters outside of the range of ``a-zA-Z0-9_-``. This scheme is explained here: :ref:`internals_tilde_encoding`. (:issue:`1657`)
 - Removed hashed URL mode from Datasette. The new ``datasette-hashed-urls`` plugin can be used to achieve the same result, see :ref:`performance_hashed_urls` for details. (:issue:`1661`)
 - Databases can now have a custom path within the Datasette instance that is independent of the database name, using the ``db.route`` property. (:issue:`1668`)
-- URLs within Datasette now use a different encoding scheme for tables or databases that include "special" characters outside of the range of ``a-zA-Z0-9_-``. This scheme is explained here: :ref:`internals_tilde_encoding`. (:issue:`1657`)
+- Datasette is now covered by a `Code of Conduct <https://github.com/simonw/datasette/blob/main/CODE_OF_CONDUCT.md>`__. (:issue:`1654`)
+- Python 3.6 is no longer supported. (:issue:`1577`)
+- Tests now run against Python 3.11-dev. (:issue:`1621`)
+- New :ref:`datasette.ensure_permissions(actor, permissions) <datasette_ensure_permissions>` internal method for checking multiple permissions at once. (:issue:`1675`)
+- New :ref:`datasette.check_visibility(actor, action, resource=None) <datasette_check_visibilty>` internal method for checking if a user can see a resource that would otherwise be invisible to unauthenticated users. (:issue:`1678`)
 - Table and row HTML pages now include a ``<link rel="alternate" type="application/json+datasette" href="...">`` element and return a ``Link: URL; rel="alternate"; type="application/json+datasette"`` HTTP header pointing to the JSON version of those pages. (:issue:`1533`)
 - ``Access-Control-Expose-Headers: Link`` is now added to the CORS headers, allowing remote JavaScript to access that header.
 - Canned queries are now shown at the top of the database page, directly below the SQL editor. Previously they were shown at the bottom, below the list of tables. (:issue:`1612`)
 - Datasette now has a default favicon. (:issue:`1603`)
 - ``sqlite_stat`` tables are now hidden by default. (:issue:`1587`)
 - SpatiaLite tables ``data_licenses``, ``KNN`` and ``KNN2`` are now hidden by default. (:issue:`1601`)
-- Python 3.6 is no longer supported. (:issue:`1577`)
-- Tests now run against Python 3.11-dev. (:issue:`1621`)
-- Fixed bug where :ref:`custom pages <custom_pages>` did not work on Windows. Thanks, Robert Christie. (:issue:`1545`)
 - SQL query tracing mechanism now works for queries executed in ``asyncio`` sub-tasks, such as those created by ``asyncio.gather()``. (:issue:`1576`)
 - :ref:`internals_tracer` mechanism is now documented.
 - Common Datasette symbols can now be imported directly from the top-level ``datasette`` package, see :ref:`internals_shortcuts`. Those symbols are ``Response``, ``Forbidden``, ``NotFound``, ``hookimpl``, ``actor_matches_allow``. (:issue:`957`)
 - ``/-/versions`` page now returns additional details for libraries used by SpatiaLite. (:issue:`1607`)
 - Documentation now links to the `Datasette Tutorials <https://datasette.io/tutorials>`__.
 - Datasette will now also look for SpatiaLite in ``/opt/homebrew`` - thanks, Dan Peterson. (`#1649 <https://github.com/simonw/datasette/pull/1649>`__)
-- Datasette is now covered by a `Code of Conduct <https://github.com/simonw/datasette/blob/main/CODE_OF_CONDUCT.md>`__. (:issue:`1654`)
+- Fixed bug where :ref:`custom pages <custom_pages>` did not work on Windows. Thanks, Robert Christie. (:issue:`1545`)
 - Fixed error caused when a table had a column named ``n``. (:issue:`1228`)

 ``ds_actor`` cookies can optionally include a signed expiry timestamp, after which the cookies will no longer be valid. Authentication plugins may chose to use this mechanism to limit the lifetime of the cookie. For example, if a plugin implements single-sign-on against another source it may decide to set short-lived cookies so that if the user is removed from the SSO system their existing Datasette cookies will stop working shortly afterwards.
 
-To include an expiry, add a ``"e"`` key to the cookie value containing a `base62-encoded integer <https://pypi.org/project/python-baseconv/>`__ representing the timestamp when the cookie should expire. For example, here's how to set a cookie that expires after 24 hours:

 Changelog
 =========
 
+.. _v0_62a0:
+
+0.62a0 (2022-05-02)
+-------------------
+
+- Datasette now runs some SQL queries in parallel. This has limited impact on performance, see `this research issue <https://github.com/simonw/datasette/issues/1727>`__ for details.
+- Datasette should now be compatible with Pyodide. (:issue:`1733`)
+- ``datasette publish cloudrun`` has a new ``--timeout`` option which can be used to increase the time limit applied by the Google Cloud build environment. Thanks, Tim Sherratt. (`#1717 <https://github.com/simonw/datasette/pull/1717>`__)
+- Spaces in database names are now encoded as ``+`` rather than ``~20``. (:issue:`1701`)
+- ``<Binary: 2427344 bytes>`` is now displayed as ``<Binary: 2,427,344 bytes>`` and is accompanied by tooltip showing "2.3MB". (:issue:`1712`)
+- Don't show the facet option in the cog menu if faceting is not allowed. (:issue:`1683`)
+- Code examples in the documentation are now all formatted using Black. (:issue:`1718`)
+- ``Request.fake()`` method is now documented, see :ref:`internals_request`.

Subject: [PATCH 1456/2321] Trying out one-sentence-per-line

As suggested here: https://sive.rs/1s

Markdown and reStructuredText will display this as if it is a single paragraph, even though the sentences themselves are separated by newlines.

This could result in more useful diffs. Trying it out on this page first.

+- The :ref:`render_cell() <plugin_hook_render_cell>` plugin hook is now also passed a ``row`` argument, representing the ``sqlite3.Row`` object that is being rendered. (:issue:`1300`)
+- New ``--nolock`` option for ignoring file locks when opening read-only databases. (:issue:`1744`)
+- Documentation now uses the `Furo <https://github.com/pradyunsg/furo>`__ Sphinx theme. (:issue:`1746`)
+- Datasette now has a `Discord community <https://discord.gg/ktd74dm5mw>`__.
+- Database file downloads now implement conditional GET using ETags. (:issue:`1739`)
+- Examples in the documentation now include a copy-to-clipboard button. (:issue:`1748`)
+- HTML for facet results and suggested results has been extracted out into new templates ``_facet_results.html`` and ``_suggested_facets.html``. Thanks, M. Nasimul Haque. (`#1759 <https://github.com/simonw/datasette/pull/1759>`__)

+Registering a plugin for the duration of a test
+-----------------------------------------------

+    from datasette.plugins import pm

+
+            # Use hookimpl and method names to register hooks

+        try:
+            # The test implementation goes here
+            datasette = Datasette()
+            response = await datasette.client.get("/error")
+            assert response.status_code == 500

-0.62a1 (2022-07-17)
+0.62 (2022-08-14)
 -------------------
 
+Datasette can now run entirely in your browser using WebAssembly. Try out `Datasette Lite <https://lite.datasette.io/>`__, take a look `at the code <https://github.com/simonw/datasette-lite>`__ or read more about it in `Datasette Lite: a server-side Python web application running in a browser <https://simonwillison.net/2022/May/4/datasette-lite/>`__.
+
+Datasette now has a `Discord community <https://discord.gg/ktd74dm5mw>`__ for questions and discussions about Datasette and its ecosystem of projects.
+
+Features
+~~~~~~~~
+
+- Datasette is now compatible with `Pyodide <https://pyodide.org/>`__.  This is the enabling technology behind `Datasette Lite <https://lite.datasette.io/>`__. (:issue:`1733`)
+- Database file downloads now implement conditional GET using ETags. (:issue:`1739`)
+- HTML for facet results and suggested results has been extracted out into new templates ``_facet_results.html`` and ``_suggested_facets.html``. Thanks, M. Nasimul Haque. (`#1759 <https://github.com/simonw/datasette/pull/1759>`__)
+- Datasette now runs some SQL queries in parallel. This has limited impact on performance, see `this research issue <https://github.com/simonw/datasette/issues/1727>`__ for details.
+- New ``--nolock`` option for ignoring file locks when opening read-only databases. (:issue:`1744`)
+- Spaces in the database names in URLs are now encoded as ``+`` rather than ``~20``. (:issue:`1701`)
+- ``<Binary: 2427344 bytes>`` is now displayed as ``<Binary: 2,427,344 bytes>`` and is accompanied by tooltip showing "2.3MB". (:issue:`1712`)
+- The base Docker image used by ``datasette publish cloudrun``, ``datasette package`` and the `official Datasette image <https://hub.docker.com/datasetteproject/datasette>`__ has been upgraded to ``3.10.6-slim-bullseye``.  (:issue:`1768`)
+- Canned writable queries against immutable databases now show a warning message. (:issue:`1728`)
+- ``datasette publish cloudrun`` has a new ``--timeout`` option which can be used to increase the time limit applied by the Google Cloud build environment. Thanks, Tim Sherratt. (`#1717 <https://github.com/simonw/datasette/pull/1717>`__)
+- ``datasette publish cloudrun`` has new ``--min-instances`` and ``--max-instances`` options. (:issue:`1779`)
+
+Plugin hooks
+~~~~~~~~~~~~
+
 - New plugin hook: :ref:`handle_exception() <plugin_hook_handle_exception>`, for custom handling of exceptions caught by Datasette. (:issue:`1770`)
 - The :ref:`render_cell() <plugin_hook_render_cell>` plugin hook is now also passed a ``row`` argument, representing the ``sqlite3.Row`` object that is being rendered. (:issue:`1300`)
-- New ``--nolock`` option for ignoring file locks when opening read-only databases. (:issue:`1744`)
-- Documentation now uses the `Furo <https://github.com/pradyunsg/furo>`__ Sphinx theme. (:issue:`1746`)
-- Datasette now has a `Discord community <https://discord.gg/ktd74dm5mw>`__.
-- Database file downloads now implement conditional GET using ETags. (:issue:`1739`)
-- Examples in the documentation now include a copy-to-clipboard button. (:issue:`1748`)
-- HTML for facet results and suggested results has been extracted out into new templates ``_facet_results.html`` and ``_suggested_facets.html``. Thanks, M. Nasimul Haque. (`#1759 <https://github.com/simonw/datasette/pull/1759>`__)
+- The :ref:`configuration directory <config_dir>` is now stored in ``datasette.config_dir``, making it available to plugins. Thanks, Chris Amico. (`#1766 <https://github.com/simonw/datasette/pull/1766>`__)

+Bug fixes
+~~~~~~~~~
 
-0.62a0 (2022-05-02)

+Setting up a Datasette test instance
+------------------------------------
+
+The above example shows the easiest way to start writing tests against a Datasette instance:
+
+.. code-block:: python
+
+    from datasette.app import Datasette
+    import pytest
+
+
+    @pytest.mark.asyncio
+    async def test_plugin_is_installed():
+        datasette = Datasette(memory=True)
+        response = await datasette.client.get("/-/plugins.json")
+        assert response.status_code == 200
+
+Creating a ``Datasette()`` instance like this as useful shortcut in tests, but there is one detail you need to be aware of. It's important to ensure that the async method ``.invoke_startup()`` is called on that instance. You can do that like this:
+
+.. code-block:: python
+
+    datasette = Datasette(memory=True)
+    await datasette.invoke_startup()
+
+This method registers any :ref:`plugin_hook_startup` or :ref:`plugin_hook_prepare_jinja2_environment` plugins that might themselves need to make async calls.
+
+If you are using ``await datasette.client.get()`` and similar methods then you don't need to worry about this - those method calls ensure that ``.invoke_startup()`` has been called for you.

+0.63a0 (2022-09-26)
+-------------------

+- The :ref:`plugin_hook_prepare_jinja2_environment` plugin hook now accepts an optional ``datasette`` argument. Hook implementations can also now return an ``async`` function which will be awaited automatically. (:issue:`1809`)
+- ``--load-extension`` option now supports entrypoints. Thanks, Alex Garcia. (`#1789 <https://github.com/simonw/datasette/pull/1789>`__)
+- New tutorial: `Cleaning data with sqlite-utils and Datasette <https://datasette.io/tutorials/clean-data>`__.
+- Facet size can now be set per-table with the new ``facet_size`` table metadata option. (:issue:`1804`)
+- ``truncate_cells_html`` setting now also affects long URLs in columns. (:issue:`1805`)
+- ``Database(is_mutable=)`` now defaults to ``True``. (:issue:`1808`)
+- Non-JavaScript textarea now increases height to fit the SQL query. (:issue:`1786`)
+- More detailed command descriptions on the :ref:`CLI reference <cli_reference>` page. (:issue:`1787`)
+- Datasette no longer enforces upper bounds on its depenedencies. (:issue:`1800`)
+- Facets are now displayed with better line-breaks in long values. Thanks, Daniel Rech. (`#1794 <https://github.com/simonw/datasette/pull/1794>`__)
+- The ``settings.json`` file used in :ref:`config_dir` is now validated on startup. (:issue:`1816`)

Plugins can store configuration, settings, and other data inside this database. By default, Datasette will use a temporary in-memory SQLite database as the internal database, which is created at startup and destroyed at shutdown. Users of Datasette can optionally pass in a `--internal` flag to specify the path to a SQLite database to use as the internal database, which will persist internal data across Datasette instances. +Datasette maintains tables called ``catalog_databases``, ``catalog_tables``, ``catalog_columns``, ``catalog_indexes``, ``catalog_foreign_keys`` with details of the attached databases and their schemas.

Previously you needed to create a token with restrictions that explicitly listed ``view-instance`` and ``view-database`` and ``view-table`` in order to view a table without getting a permission denied error. (:issue:`2102`) +- New ``datasette.yaml`` (or ``.json``) configuration file, which can be specified using ``datasette -c path-to-file``. The goal here to consolidate settings, plugin configuration, permissions, canned queries, and other Datasette configuration into a single single file, separate from ``metadata.yaml``. The legacy ``settings.json`` config file used for :ref:`config_dir` has been removed, and ``datasette.yaml`` has a ``"settings"`` section where the same settings key/value pairs can be included. In the next future alpha release, more configuration such as plugins/permissions/canned queries will be moved to the ``datasette.yaml`` file. See :issue:`2093` for more details. Thanks, Alex Garcia. +- The ``-s/--setting`` option can now take dotted paths to nested settings. These will then be used to set or over-ride the same options as are present in the new configuration file. (:issue:`2156`) +- New ``--actor '{"id": "json-goes-here"}'`` option for use with ``datasette --get`` to treat the simulated request as being made by a specific actor, see :ref:`cli_datasette_get`. (:issue:`2153`) +- The Datasette ``_internal`` database has had some changes. It no longer shows up in the ``datasette.databases`` list by default, and is now instead available to plugins using the ``datasette.get_internal_database()``. Plugins are invited to use this as a private database to store configuration and settings and secrets that should not be made visible through the default Datasette interface. Users can pass the new ``--internal internal.db`` option to persist that internal database to disk. Thanks, Alex Garcia.

(:issue:`2101`) + +The only alter operation supported so far is adding new columns to an existing table. + +* The :ref:`/db/-/create ` API now adds new columns during large operations to create a table based on incoming example ``"rows"``, in the case where one of the later rows includes columns that were not present in the earlier batches. This requires the ``create-table`` but not the ``alter-table`` permission. +* When ``/db/-/create`` is called with rows in a situation where the table may have been already created, an ``"alter": true`` key can be included to indicate that any missing columns from the new rows should be added to the table. This requires the ``alter-table`` permission. +* :ref:`/db/table/-/insert ` and :ref:`/db/table/-/upsert ` and :ref:`/db/table/row-pks/-/update ` all now also accept ``"alter": true``, depending on the ``alter-table`` permission. + +Operations that alter a table now fire the new :ref:`alter-table event `. + +Permissions fix for the upsert API +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The :ref:`/database/table/-/upsert API ` had a minor permissions bug, only affecting Datasette instances that had configured the ``insert-row`` and ``update-row`` permissions to apply to a specific table rather than the database or instance as a whole.
