An attempt to future-proof older Caddy instances so that they won't
keep trying to send telemetry to endpoints that just simply aren't
going to be available
* caddy: Purge event hooks after USR1 reload
* caddy: Remove event hook purge logging
* caddy: Remove deleteEventHook
* caddy: use old event hooks in case of an unsuccessful restart
* caddy: implement restoreEventHooks
Also add SSL_PROTOCOL and SSL_CIPHER env vars for fastcgi.
* Implement placeholders for ssl_protocol and ssl_cipher
* gofmt
* goimports
* Housekeeping and implement as {tls_protocol} and {tls_cipher}
* tls: Fall back to certificate keyed by empty name (fixes#2035)
This should only happen for sites defined with an empty hostname (like
":8080") and which are using self-signed certificates or some other
funky self-managed certificate. But that certificate should arguably
be used for all incoming SNI names.
* tls: Revert to serving any certificate if no match, regardless of SNI
Also fix self-signed certs to include IP addresses in their name
if they are configured to serve an IP address
* Remove tests which are now irrelevant (behavior reverted)
It would be good to revisit this in the future.
Caddy can now obtain certificates when behind load balancers and/or in
fleet/cluster configurations, without needing any extra configuration.
The only requirement is sharing the same $CADDYPATH/acme folder.
This works with the HTTP challenge, whereas before the DNS challenge
was required. This commit allows one Caddy instance to initiate the
HTTP challenge and another to complete it.
When sharing that folder, certificate management is synchronized and
coordinated, without the Caddy instances needing to know about each
other. No load balancer reconfiguration should be required, either.
Currently, this is only supported when using FileStorage for TLS
storage (which is ~99.999% of users).
- 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
* Allow Response Headers in logs
* Remove log line
* remove unneeded log import
* Check if rr is nil. Added test to check
* merge if statements
* remove temp file
* Trim path prefix using EscapedPath()
* clarify comments
* Added Tests for trimPathPrefix
* Ensure path with trailing slash is properly trimmed
* Updated tests to match prepatch behaviour
* Updated tests to match prepatch behaviour
* call parse on url rather than instance
* add additional tests
* return unmodified url if error. Additional tests
Only strip the port from the Location URL value if the port is NOT the
HTTPSPort (before, we compared against DefaultHTTPSPort instead of
HTTPSPort). The HTTPSPort can be changed, but is done so for port
forwarding, since in reality you can't 'change' the standard HTTPS port,
you can only forward it.
See discussion on #2015; the initial change had removed this check, and
I can't remember why I removed it or if it was accidental. Anyway, it's
back now.
See discussion on #2015 for how this situation was discovered. For a
Caddyfile like this:
localhost {
...
}
:2015 {
...
}
Running Caddy like this:
caddy -host localhost
Produces two sites both defined as `localhost:2015` because the flag
changes the default host value to be `localhost`. This should be an
error since the sites are not distinct and it is confusing. It can also
cause issues with TLS handshakes loading the wrong cert, as the linked
discussion shows.
Also introduce caddy.OnProcessExit which is a list of functions that
run before exiting the process cleanly; these do not count as shutdown
callbacks, so they do not return errors and must execute quickly.
Fixes#1961
According to RFC 7231 and RFC 7230, there's
no reason a GET-Request can't have a body
(other than it possibly not being supported
by existing software). It's use is simply not
defined, and is left to the application.
