* Initial concept for pluggable storage (sans tests and docs)
* Add TLS storage docs, test harness, and minor clean up from code review
* Fix issue with caddymain's temporary moveStorage
* Formatting improvement on struct array literal by removing struct name
* Pluggable storage changes:
* Change storage interface to persist all site or user data in one call
* Add lock/unlock calls for renewal and cert obtaining
* Key fields on composite literals
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!!
Fixes a surplus — next to "go up".
Identifies the preamble as the table's summary.
Emits filesizes in bytes, which can be consumed by any browser-side scripts
or utilized in sorting when the table is copy-and-pasted into a spreadsheet
software.
Uses <time> along with proper datetime representation, which a browser could
utilize to display the datetime rendered according to the requestor's locale.
Caddyfile parameter "clients" of "tls" henceforth accepts a special
first modifier. It is one of, and effects:
* request = tls.RequestClientCert
* require = tls.RequireAnyClientCert
* verify_if_given = tls.VerifyClientCertIfGiven
* (none) = tls.RequireAndVerifyClientCert
The use-case for this is as follows: A middleware would serve items to the
public, but if a certificate were given the middleware would permit file
manipulation.
And, in a different plugin such as a forum or blog, not verifying a client
cert would be nice for registration: said blog would subsequently only
compare the SPKI of a client certificate.
As discussed with @mholt I have dropped the old LinkedPath function and
replaced it within the browse template with the new BreadcrumbMap
function. Visually it looks exactly the same as before, now the template
functionality is just more powerful.

In order to have directly a link within the browse listing I have added
a link to the top of the table to get one level up in the tree. Added
that after a chat with @mholt.

Nuke pre-generation. This may come back in the form of a more general
caching layer at some later stage.
Nuke index generation. This should likely be rethought and re-implemented.
Right now it has a very simple configuration:
expvar /debug/vars
It will return a JSON object with memory statistics and the command line
used to start caddy, which are the two expvars that expvar registers by
default.
