* Remove unnecessary config options from systemd service so it will work with earlier versions of systemd. Simplify the systemd service instructions and make them more complete.
* Minor systemd README improvements.
* Add back some of the optional systemd 229 stuff but commented out for compat.
* A bunch of updates to the README for linux systemd.
* Updated FreeBSD init script to allow the server to stop properly
* Fixed FreeBSD init script permissions
* Updated FreeBSD init script to allow the server to stop properly
`$(which setcap)` might evaluate to nothing,
and this way the error thrown will be more clear.
If setcap is not available on Debian/Ubuntu,
you can install the package `libcap2-bin`
* dist/init/linux-sysvinit: pass --oknodo for --start as well
* dist/init/linux-sysvinit: manually rm PIDFILE
Since start-stop-daemon --remove-pidfile is new and not present
everywhere.
These changes span work from the last ~4 months in an effort to make
Caddy more extensible, reduce the coupling between its components, and
lay a more robust foundation of code going forward into 1.0. A bunch of
new features have been added, too, with even higher future potential.
The most significant design change is an overall inversion of
dependencies. Instead of the caddy package knowing about the server
and the notion of middleware and config, the caddy package exposes an
interface that other components plug into. This does introduce more
indirection when reading the code, but every piece is very modular and
pluggable. Even the HTTP server is pluggable.
The caddy package has been moved to the top level, and main has been
pushed into a subfolder called caddy. The actual logic of the main
file has been pushed even further into caddy/caddymain/run.go so that
custom builds of Caddy can be 'go get'able.
The HTTPS logic was surgically separated into two parts to divide the
TLS-specific code and the HTTPS-specific code. The caddytls package can
now be used by any type of server that needs TLS, not just HTTP. I also
added the ability to customize nearly every aspect of TLS at the site
level rather than all sites sharing the same TLS configuration. Not all
of this flexibility is exposed in the Caddyfile yet, but it may be in
the future. Caddy can also generate self-signed certificates in memory
for the convenience of a developer working on localhost who wants HTTPS.
And Caddy now supports the DNS challenge, assuming at least one DNS
provider is plugged in.
Dozens, if not hundreds, of other minor changes swept through the code
base as I literally started from an empty main function, copying over
functions or files as needed, then adjusting them to fit in the new
design. Most tests have been restored and adapted to the new API,
but more work is needed there.
A lot of what was "impossible" before is now possible, or can be made
possible with minimal disruption of the code. For example, it's fairly
easy to make plugins hook into another part of the code via callbacks.
Plugins can do more than just be directives; we now have plugins that
customize how the Caddyfile is loaded (useful when you need to get your
configuration from a remote store).
Site addresses no longer need be just a host and port. They can have a
path, allowing you to scope a configuration to a specific path. There is
no inheretance, however; each site configuration is distinct.
Thanks to amazing work by Lucas Clemente, this commit adds experimental
QUIC support. Turn it on using the -quic flag; your browser may have
to be configured to enable it.
Almost everything is here, but you will notice that most of the middle-
ware are missing. After those are transferred over, we'll be ready for
beta tests.
I'm very excited to get this out. Thanks for everyone's help and
patience these last few months. I hope you like it!!
The exemplary unit file for systemd is intentionally redundant at times, for
example dropping privileges which an unprivileged user "www-data" did not have
in the first place: To aid as fallback in case the file gets copied and an
operator setting UID to 0 (which reportedly happened in the past).
Easier parallelism and more control over platforms we build for, but
more importantly, we can do parallel builds using the build script which
properly embeds version information into the binaries. We also produce
the archive files ourselves and in parallel rather than using external
tar and zip commands.
When thy variables henceforth accept blessed white-space,
guided will thy scripture be along righteous path(s).

Caddy's dist files sometimes ended up being owned by matt:staff or other
quite arcane and/or frightening names. If someone extracting didn't pay
attention a regular user who happened to have same uid by accident could
later tamper with the files' contents. It's 0:0 from now on.
Use all available threads when packaging distributables
Caddy binaries will be added to their archives in-place: This change
eliminates them being renamed within dist/builds one after another.
As does 'gox', dist/automate.sh will spare one available thread if possible.
Unlike network.target the network-online.target guarantees that the network
devices are online.
If you bind to 0.0.0.0, [::], [::1], and/or 127.0.0.1 only that is enough to
proceed. But in case a particular IP is needed, like ${COREOS_PUBLIC_IPV4},
we require any IP assignments to have completed before Caddy's start. That
is achieved by depending on systemd-networkd-wait-online.service (which is
scheduled before network-online.target, then, automatically).
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
