# The database URL for the database 0x0 should use
#
# See https://docs.sqlalchemy.org/en/20/core/engines.html#backend-specific-urls
# for help configuring these for your database.
#
# For small and medium servers, it's plenty sufficient to just use an sqlite
# database.  In this case, the database URI you want to use is just
#
# sqlite:/// + /path/to/your/database.db
#
# Until https://git.0x0.st/mia/0x0/issues/70 is resolved, it's recommended that
# any sqlite databases use an absolute path, as relative paths aren't consistently
# resolved.

# The maximum allowable upload size, in bytes
#
# Keep in mind that this affects the expiration of files as well!  The closer a
# file is to the max content length, the less time it will last before being
# deleted.

# with a 414 REQUEST URI TOO LONG.

# The minimum and maximum amount of time we'll retain a file for
#
# Small files (nearing zero bytes) are stored for the longest possible expiration date,
# while larger files (nearing MAX_CONTENT_LENGTH bytes) are stored for the shortest amount
# of time.  Values between these two extremes are interpolated with an exponential curve,
# like the one shown on the index page.
#
# All times are in milliseconds.  If you want all files to be stored for the same amount
# of time, set these to the same value.

USE_X_SENDFILE = False


# Use X-Accel-Redirect to speed up serving files w/ compatible webservers
#
# Other webservers, like nginx and Caddy, use the X-Accel-Redirect header to
# accomplish a very similar thing to X-Sendfile (above).  If your webserver is
# configured to do this, set this variable to True
#
# Note:  It's recommended that you use either X-Sendfile or X-Accel-Redirect
# when you deploy in production.

# The maximum acceptable user-specified file extension
#
# When a user uploads a file, in most cases, we keep the file extension they
# provide.  But!  If the specified file extension is longer than
# FHOST_MAX_EXT_LENGTH, we truncate it.  So if a user tries to upload the file
# "myfile.withareallongext", but FHOST_MAX_EXT_LENGTH is set to 9, then the
# extension that we keep is ".withareal"
FHOST_MAX_EXT_LENGTH = 9


# A list of filetypes to use when the uploader doesn't specify one
#
# When a user uploads a file with no file extension, we try to find an extension that
# works for that file.  This configuration option is the first thing that we check.  If
# the type of a file without an extension is in this dict, then it'll be used as the file
# extension for that file. Otherwise, we try to pick something sensible from libmagic's
# database.
#
# For example, if the user uploads "myfile" with no extension, and the file is a jpeg
# image, the file will get a URL like "eAa.jpg"
#
