A server can indicate a soft failure by returning 412 (Precondition
Failed). Only a warning (instead of error) message is logged and
download is retried with next server, without counting server error.
This http code can be used by servers that are not expected to be
complete, for example when serving a local cache.
I am open to changes, only important is that server error count does not
increase. So how about...
* http code: We need something >= 400 for the code to behave correctly.
Nothing fits perfectly... Do you think anything else matches better? Or
should we use a proprietary code 9xx?
* log message: Is wording and severity ok?
* Where to document the behavior?
I would say that 412 is not the right status code to use for this, since
it already has a very specific different purpose.
Another thing to consider is that normal server software won't know to
generate a different error code, so it will just return a 404 anyway. If
you need specific support from the server software, you are probably
better off with a custom header: X-Pacman-Expected-Failure or something
along those lines. Then you don't have to violate the HTTP standard to
get the desired behavior.
Although from a user perspective it would probably be simpler to put
this information in the pacman.conf than to configure their HTTP server.
Kind regards,
