Reworked HTTP/2 release after an exchange is terminated. Previously, the release was bound to 2 events: onStreamClosed(), introduced for #2796, and exchangeTerminated(). Unfortunately, if the former happens before the latter and closes the connection, the latter will see the exchange as aborted, while in fact it was successful, causing what reported in #5147, an AsynchronousCloseException. Now, the release is always performed by the exchangeTerminated() event. With respect to #2796, the stream is always already closed by the time the exchangeTerminated() event fires (it was not before). Reworked the implementation of RoundRobinConnectionPool using a lock and aggressively trying to open new connections. A second fix is related to HttpDestination.release(Connection). If the connection is closed for e.g. overuse, we need to trigger the processing of queued requests via send(create: true). Signed-off-by: Simone Bordet <simone.bordet@gmail.com>

Project description
Jetty is a lightweight highly scalable java based web server and servlet engine. Our goal is to support web protocols like HTTP, HTTP/2 and WebSocket in a high volume low latency way that provides maximum performance while retaining the ease of use and compatibility with years of servlet development. Jetty is a modern fully async web server that has a long history as a component oriented technology easily embedded into applications while still offering a solid traditional distribution for webapp deployment.
Documentation
Project documentation is available on the Jetty Eclipse website.
Building
To build, use:
mvn clean install
The Jetty distribution will be built in jetty-distribution/target/distribution
.
The first build may take a longer than expected as Maven downloads all the dependencies.
The build tests do a lot of stress testing, and on some machines it is necessary to set the file descriptor limit to greater than 2048 for the tests to all pass successfully.
It is possible to bypass tests by building with mvn clean install -DskipTests
.
