Add systemd service file for caddy
Add some README with basic setup instructions
Explain how to view the service configuration
Add a note about permissions
Add a comment about run user and group
service->service unit
A systemd service can consist of different units. A unit configuration
file has the `.service` file ending which is a bit confusing, so please
be considerate if I'm confusing `service` and `unit` in the README
Fix typos/reword
Add contact information
- The mime middleware used filepath where it should arguably use path.
- Changed the configuration to use a map instead of scanning an array
during every request. The map is static (after configuration), so
should be fine for concurrent access.
- Catch duplicate extensions within a configuration and error out.
- Add tests for new error case.
Minor change to server/server.go such that /.well-known/acme-challenge
can be passed through when TLS.Manual is true on the vhost the request
came in through.
fastcgi's ServeHTTP method originally returned the correct value (0) in
b51e8bc191. Later, I mistakenly suggested
we change that to return the status code because I forgot that status
codes aren't logged by the return value. So fastcgi broke due in
3966936bd6 due to my error.
We later had to try to make up for this with ugly Content-Length checks
like in c37ad7f677. Turns out that all we
had to do was fix the returned status here back to 0. The proxy
middleware behaves the same way, and returning 0 is correct. We should
only return a status code if the response has not been written, but with
upstream servers, we do write a response; they do not know about our
error handler.
Also clarifed this in the middleware.Handler documentation.
Without -ldflags, the verison information needs to be updated manually,
which is never done between releases, so development builds appear
indiscernable from stable builds using `caddy -version`.
This is part of a set of changes intended to relieve the burden of
always updating version information manually and distributing binaries
that look stable but actually may not be.
A stable build is defined as one which is produced at a git tag with
a clean working directory (no uncommitted changes). A dev build is
anything else. With this build script, `caddy -version` will now reveal
whether it is a development build and, if so, the base version, the
latest commit, the date and time of build, and the names of files with
changes as well as how many changes were made.
The output of `caddy -version` for stable builds remains the same.
