* tls: Add support for the tls-alpn-01 challenge
Also updates lego/acme to latest on master.
TODO: This implementation of the tls-alpn challenge is not yet solvable
in a distributed Caddy cluster like the http challenge is.
* build: Allow building with the race detector
* tls: Support distributed solving of the TLS-ALPN-01 challenge
* Update vendor and add a todo in MITM checker
- Using xenolf/lego's likely-temporary acmev2 branch
- Cleaned up vendor folder a little bit (probably more to do)
- Temporarily set default CA URL to v2 staging endpoint
- Refactored user management a bit; updated tests (biggest change is
how we get the email address, which now requires being able to make
an ACME client with a User with a private key so that we can get the
current ToS URL)
- Automatic HTTPS now allows specific wildcard pattern hostnames
- Commented out (but kept) the TLS-SNI code, as the challenge type
may return in the future in a similar form
The vendor/ folder was created with the help of @FiloSottile's gvt and
vendorcheck.
Any dependencies of Caddy plugins outside this repo are not vendored.
We do not remove any unused, vendored packages because vendorcheck -u
only checks using the current build configuration; i.e. packages that
may be imported by files toggled by build tags of other systems.
CI tests have been updated to ignore the vendor/ folder. When Go 1.9 is
released, a few of the go commands should be revised to again use ./...
as it will ignore the vendor folder by default.
