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.
* 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
Modules that return an error during provisioning should still be cleaned
up so that they don't leak any resources they may have allocated before
the error occurred. Cleanup should be able to run even if Provision does
not complete fully.
./caddy.go:230:12: cannot use *dep (type debug.Module) as type *debug.Module in return argument
./caddy.go:233:12: cannot use bi.Main (type debug.Module) as type *debug.Module in return argument
* optimized functions for inlining
* added note regarding ResponseWriterWrapper
* optimzed browseWrite* methods for FileServer
* created benchmarks for comparison
* creating browseListing instance in each function
* created benchmarks for openResponseWriter
* removed benchmarks of old implementations
* implemented sync.Pool for byte buffers
* using global sync.Pool for writing JSON/HTML
Tested for memory leaks and performance. Obviously the added locking and
global state is not awesome, but the alternative is a little uglier IMO:
we'd have to make some sort of "liaison" value which stores the state,
then pass it around to every module, and so LoadModule becomes a lot
less accessible, and each module would need to maintain a reference to
it... nope, just ugly. I think this is the cleaner solution: just make
sure only one Start() happens at a time, and keep global things global.
Very simple log middleware is an example.
Might need to reorder the operations in Start() and handle errors
differently, etc. Otherwise, I'm mostly happy with this solution...
