* Add support for placeholders in Config
Fixes#2870
* Replace placeholders only in logging config.
Placeholders in log level and filename incase of file output are replaced.
* Add Provision to filewriter module for replacing placeholders
Errors in the 4xx range are client errors, and they don't need to be
entered into the server's error logs. 4xx errors are still recorded in
the access logs at the error level.
This makes it easier to make "standard" caddy builds, since you'll only
need to add a single import to get all of Caddy's standard modules.
There is a package for all of Caddy's standard modules (modules/standard)
and a package for the HTTP app's standard modules only
(modules/caddyhttp/standard).
We still need to decide which of these, if not all of them, should be
kept in the standard build. Those which aren't should be moved out of
this repo. See #2780.
First evidenced in #2658, listener deadlines would sometimes be set
after clearing them, resulting in endless i/o timeout errors, which
leave all requests hanging. This bug is fixed by synchronizing the
calls to SetDeadline: when Close() is called, the deadline is first
set to a time in the past, and the lock is released only after the
deadline is set, so when the other servers break out of their Accept()
calls, they will clear the deadline *after* it was set. Before, the
clearing could sometimes come before the set, which meant that it was
left in a timeout state indefinitely.
This may not yet be a perfect solution -- ideally, the setting and
clearing of the deadline would happen exactly once per underlying
listener, not once per fakeCloseListener, but in rigorous testing with
these changes (comprising tens of thousands of config reloads), I was
able to verify that no race condition is manifest.
Fixed several bugs and made other improvements. All config changes are
now mediated by the global config state manager. It used to be that
initial configs given at startup weren't tracked, so you could start
caddy with --config caddy.json and then do a GET /config/ and it would
return null. That is fixed, along with several other general flow/API
enhancements, with more to come.
* Always cleanup admin endpoint first
* Error out if no config has been set (#2833)
* Ignore explicitly missing admin config (#2833)
* Separate config loading from admin initialization (#2833)
* Add admin option to specify admin listener address (#2833)
* Use zap for reporting admin endpoint status
* fuzz: add missing fuzzer by fixing .gitignore adding a negation for caddyfile/ directory
* ci: print fuzzing type for debuggability and traceability
* README: update the Fuzzit badge to point to the correct Caddy server Github organization
Not really necessary; underlying work is done by json.Unmarshal which
is part of the Go standard lib. Also, it called Run, which potentially
tries to get certificates; we should not let that happen.
* logging: Initial implementation
* logging: More encoder formats, better defaults
* logging: Fix repetition bug with FilterEncoder; add more presets
* logging: DiscardWriter; delete or no-op logs that discard their output
* logging: Add http.handlers.log module; enhance Replacer methods
The Replacer interface has new methods to customize how to handle empty
or unrecognized placeholders. Closes#2815.
* logging: Overhaul HTTP logging, fix bugs, improve filtering, etc.
* logging: General cleanup, begin transitioning to using new loggers
* Fixes after merge conflict
* fuzz-ci: fix the authentication call for fuzzit by using the --api-key flag rather than the `auth` command
* Allow fuzzing on schedules as well as non-fork PRs
Closes#2710
* fuzz: lay down the foundation for continuous fuzzing
* improve the fuzzers and add some
* fuzz: add Fuzzit badge to README & enable fuzzers submission in CI
* v2-fuzz: do away with the submodule approach for fuzzers
* fuzz: enable fuzzit
* v2: speed up some of powershell's processes
* v2-ci: downloading latest Go on Windows isn't slow anymore, so update the log message accordingly
* v2: CI: use 7z on Windows instead of Expand-Archive
* file_server: Make tests work on Windows
* caddyfile: Fix escaping when character is not escapable
We only escape certain characters depending on inside or outside of
quotes (mainly newlines and quotes). We don't want everyone to have to
escape Windows file paths like C:\\Windows\\... but we can't drop the
\ either if it's just C:\Windows\...
* v2: split golangci-lint configuration into its own file to allow code editors to take advantage of it
* v2: simplify code
* v2: set the correct lint output formatting
* v2: invert the logic of linter's configuration of output formatting to allow the editor convenience over CI-specific customization. Customize the output format in CI by passing the flag.
* v2: remove irrelevant golangci-lint config
