The "/sqlar" page:

Generate a ZIP or SQL archive for the check-in specified by the "r" query parameter. Return the archive as the HTTP reply content.

If the NAME contains one "/" then the part before the "/" is taken as the TAG and the part after the "/" becomes the true name. Hence, the following URLs are all equivalent:

/sqlar/508c42a6398f8/download.sqlar
/sqlar?r=508c42a6398f8&name=download.sqlar
/sqlar/download.sqlar?r=508c42a6398f8
/sqlar?name=508c42a6398f8/download.sqlar

Query parameters:

name=NAME
The base name of the output file. The default value is a configuration parameter in the project settings. A prefix of the name, omitting the extension, is used as the top-most directory name.

r=TAG
The check-in that is turned into a ZIP archive. Defaults to "trunk". This query parameter used to be called "uuid" and the older "uuid" name is still accepted for backwards compatibility. If this query parameter is omitted, the latest "trunk" check-in is used.

in=PATTERN
Only include files that match the comma-separate list of GLOB patterns in PATTERN, as with ex=

ex=PATTERN
Omit any file that match PATTERN. PATTERN is a comma-separated list of GLOB patterns, where each pattern can optionally be quoted using ".." or '..'. Any file matching both ex= and in= is excluded.
