This change eliminates the `[ERROR] Could not write pidfile: open /var/run/caddy.pid: permission denied` from caddy.log.
The start-stop-daemon writes the file as root so the DAEMONUSER that caddy runs as cannot write to the .pid file.
* Proxy can now use QUIC for upstream connections
Add HandshakeTimeout, change h2quic syntax
* Add setup and upstream test
Test QUIC proxy with actual h2quic instance
Use different port fo QUIC test server
Add quic host to CI config
Added testdata to vendor
Revert "Added testdata to vendor"
This reverts commit 959512282deed8623168d090e5ca5e5a7933019c.
* Use local testdata
Renewed certificates would not be reloaded into the cache because their
names conflict with names of certificates already in the cache; this
was intentional when loading new certs to avoid confusion, but is
problematic when renewing, since the old certificate doesn't get
evicted from the cache. (Oops.)
Here, I remedy this situation by explicitly deleting the old cert from
the cache before adding the renewed one back in.
(See EULA.) Personally-licensed official Caddy builds cannot remove
this header by configuration. The commercially-licensed builds of Caddy
don't have this header.
* Allow pushing multiple resources via Link header
* Add nopush test case
* Extract Link header parsing to separate function
* Parser regexp-free
* Remove dead code, thx gometalinter
* Redundant condition - won't happen
* Reduce duplication
* browse: Attempt to fix tests on Windows
* browse: Make tests verbose for debugging
* Moar debugging
* Trying path.Join instead
* browse: Just skip the tests for now
* browse: Remove debug prints
build.go is (should be) cross-platform compatible.
Timestamps are now excluded from all builds on a clean commit,
in an effort to be byte-for-byte reproducible.
* templates: Execute template loaded by later middlewares
This is the beginning of an attempt to make the staticfiles file server
the only middleware that hits the disk and loads content. This may have
unknown implications. But the goal is to reduce duplication without
sacrificing performance. (We now call ServeContent here.)
This change loses about 15% of the req/sec of the old way of doing it,
but this way is arguably more correct since the file server is good at
serving static files; duplicating that logic in every middleware that
needs to hit the disk is not practical.
* httpserver: Introduce ResponseRecorder as per Tw's suggestions
It implements io.ReaderFrom and has some allocation-reducing
optimizations baked into it
* templates: Increase execution speed by ~10-15% after perf regression
By using httpserver.ResponseBuffer, we can reduce allocations and still
get what we want. It's a little tricky but it works so far.
The previous setting caused the service to hit a rate-limit when it was
restarted more than 5 times in 24h.
Editing the Caddyfile and restarting the service could also easily
trigger this rate limit.
One could argue that users could simply call `systemctl reset-failed
caddy` to reset the rate-limit counter, but this is counterintuitive
because most users won't know this command and are possibly unaware that
they had hit a rate-limit.
The service is now allowed to restart 10 times in 10 seconds before
hitting a rate limit.
This should be conservative enough to rate limit quickly failing
services and to allow users to edit and test their caddy configuration.
This closes#1718
Remove restart limit settings and use defaults
By default 5 restarts within 10 seconds are allowed without
encountering a restart limit hit, see `man systemd.unit` for details.
Set Restart to on-abnormal
The table in https://www.freedesktop.org/software/systemd/man/systemd.service.html#Restart=
shows the conditions for which on-abnormal would restart the service.
It will *not* restart the service in the following cases:
- a non-zero exit status, e.g. an invalid Caddyfile
- a zero exit code (or those specified in SuccessExitStatus=) and a clean signal
clean signals are SIGHUP, SIGINT, SIGTERM or SIGPIPE
3536f49e8f/src/basic/exit-status.c (L205)
The service *will be restarted* in the following cases:
- a unclean signal, e.g. SIGKILL
- on start and watchdog timeout (we don't use those systemd service
constructs explicitly)
* SIGUSR2 triggers graceful binary upgrades (spawns new process)
* Move some functions around, hopefully fixing Windows build
* Clean up a couple file closes and add links to useful debugging thread
* Use two underscores in upgrade env var
To help ensure uniqueness / avoid possible collisions

Certificates are keyed by name in the cache, optimized for fast lookups
during TLS handshakes using SNI. A more "correct" way that is truly a
1:1 would be to cache certificates by a hash of the leaf's DER bytes,
but this involves an extra index to maintain. So instead of that, we
simply choose to prevent overlap when keying certificates by server
name. This avoids the ambiguity when updating OCSP staples, for instance.
