db: cache SCM instance short-term (tied to SQLAlchemy session lifetime)
Repeatedly checking whether SCM instances are invalidated is slow, and
we don't actually _want_ SCM instances to invalidate half-way through
a request either.
Therefore cache them in on the db.Repository object, the lifetime
of which is directly tied to the lifetime of the SQLAlchemy session,
the lifetime of which is tied directly to the individual HTTP request.
This way, we only check for invalidation the first time the SCM instance
is accessed in a request.
This will improve performance in cases where we have (by definition) badly
written code that retrieves repo objects several times.

.. _email: ============== Email settings ============== The Kallithea configuration file has several email related settings. When these contain correct values, Kallithea will send email in the situations described below. If the email configuration is not correct so that emails cannot be sent, all mails will show up in the log output. Before any email can be sent, an SMTP server has to be configured using the configuration file setting ``smtp_server``. If required for that server, specify a username (``smtp_username``) and password (``smtp_password``), a non-standard port (``smtp_port``), encryption settings (``smtp_use_tls`` or ``smtp_use_ssl``) and/or specific authentication parameters (``smtp_auth``). Application emails ------------------ Kallithea sends an email to `users` on several occasions: - when comments are given on one of their changesets - when comments are given on changesets they are reviewer on or on which they commented regardless - when they are invited as reviewer in pull requests - when they request a password reset Kallithea sends an email to all `administrators` upon new account registration. Administrators are users with the ``Admin`` flag set on the *Admin > Users* page. When Kallithea wants to send an email but due to an error cannot correctly determine the intended recipients, the administrators and the addresses specified in ``email_to`` in the configuration file are used as fallback. Recipients will see these emails originating from the sender specified in the ``app_email_from`` setting in the configuration file. This setting can either contain only an email address, like `kallithea-noreply@example.com`, or both a name and an address in the following format: `Kallithea <kallithea-noreply@example.com>`. However, if the email is sent due to an action of a particular user, for example when a comment is given or a pull request created, the name of that user will be combined with the email address specified in ``app_email_from`` to form the sender (and any name part in that configuration setting disregarded). The subject of these emails can optionally be prefixed with the value of ``email_prefix`` in the configuration file. Error emails ------------ When an exception occurs in Kallithea -- and unless interactive debugging is enabled using ``set debug = true`` in the ``[app:main]`` section of the configuration file -- an email with exception details is sent by WebError_'s ``ErrorMiddleware`` to the addresses specified in ``email_to`` in the configuration file. Recipients will see these emails originating from the sender specified in the ``error_email_from`` setting in the configuration file. This setting can either contain only an email address, like `kallithea-noreply@example.com`, or both a name and an address in the following format: `Kallithea Errors <kallithea-noreply@example.com>`. *Note:* The WebError_ package does not respect ``smtp_port`` and assumes the standard SMTP port (25). If you have a remote SMTP server with a different port, you could set up a local forwarding SMTP server on port 25.
