Testing was conducted only using explicit parameters, and using
testsuite. However, when the parameters are not explicitly set in JSON
config, it seems that `c.MaxUploadSize` will contain `RandRangeConfig {
From: 0, To: 0 }` instead of `nil`, which breaks upload entirely.
* maxUploadSize and maxConcurrentUploads can now be ranges on the client
* maxUploadSize is now enforced on the server
* the default of maxUploadSize is 2MB on the server, and 1MB on the client
* the default of maxConcurrentUploads is 200 on the server, and 100 on the client
* ranges on the server are treated as a single number. if server is configured as `"1-2"`, server will enforce `2`
* querystrings in `path` are now handled correctly
When Close and Push are called concurrently, it may happen that Push attempts to write to an already-closed channel, and trigger a panic.
From a user perspective, it results in logs like this:
http: panic serving 172.19.0.6:50476: send on closed channel
It's probably triggered when download is closed at the same time an upload packet is submitted.
These panics don't crash the server and the inbound is still usable.
Fix#3566
Also update testsuite so that all tests read and write some data. Opening a connection is not enough to trigger connection errors, because the connection is so lazy.
* Refactor log
* Add new log methods
* Fix logger test
* Change all logging code
* Clean up pathObj
* Rebase to latest main
* Remove invoking method name after the dot
* Add H2C support to server
* update comment
* Make http1.1 ALPN work on SplitHTTP client
Users that encounter protocol version issues will likely try to set the
ALPN explicitly. In that case we should simply grant their wish, because
the intent is obvious.
