* 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

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.
Updated ifCondition test to deep test all fields.
Changed NewComplexRule to not return a pointer.
Corrected panic detection in formatting.
Fixed failing test cases.
Fixed review bug for test.
Fixes bug caused by Replacer running on the regular expressions in IfMatcher. We also now compile regular expressions up front to detect errors.
Fixes rewrite bugs that come from formatting a rule as a string and failing with nil dereference caused by embedding Regexp pointer in a Rule. Re: Issue #1794
0: normal or expected exit
1: error before server finished starting
2: double SIGINT (force quit)
3: error stopping with SIGQUIT
4: shutdown callback(s) returned error(s)
