* Issue #3806 async sendError
Avoid using isHandled as a test withing sendError as this can be
called asynchronously and is in a race with the normal dispatch of the
request, which could also be setting handled status.
The ErrorHandler was dispatching directly to a context from within
sendError. This meant that an async thread can call sendError and be
dispatched to within the servlet container at the same time that the
original thread was still dispatched to the container.
This commit fixes that problem by using an async dispatch for error
pages within the ErrorHandler. However, this introduces a new problem
that a well behaved async app will call complete after calling
sendError. Thus we have ignore complete ISEs for the remainder of
the current async cycle.
Fixed the closing of the output after calling sendError. Do not
close if the request was async (and thus might be dispatched to an
async error) or if it is now async because the error page itself is
async.
* updates from review
* better tests
* revert ignore complete
* added some TODOs
* more TODOs
* fixed rename
* cleanup ISE and more TODOs
* refactored to call sendError for uncaught exceptions rather than onError
* more of the refactor
* extra tests for sendError from completing state
Reworked HttpChannelState and sendError so that sendError is now
just a change of state. All the work is done in the ErrorDispatch
action, including calling the ErrorHandler. Async not yet working.
Additional tests
Converted ERRORED state to a separate boolean so it can be used for
both Sync and Async dispatches.
Removed ASYNC_IO state as it was just the same as DISPATCHED
The async onError listener handling is now most likely broken.
WIP making sendError simpler and more tests pass
WIP handling async and thrown exceptions
WIP passing tests
Improved thread handling
removed bad test
Implemented error dispatch on complete properly
more fixed tests
sendError state looks committed
- Added resetContent method to leave more non-content headers during sendError
- Fixed security tests
- simplified the non dispatch error page writing. Moved towards being able to write async
* fixed gzipHandlerTest
* Updated handling of timeout errors. According to servlet spec,
exceptions thrown from onTimeout should not be passed to onError, but
just logged and ignored:
If an exception is thrown while invoking methods in an AsyncListener,
it is logged and will not affect the invocation of any other AsyncListeners.
* This changes several tests.
* Dispatcher/ContextHandler changes for new ERROR dispatch handling. Feels a bit fragile!
* Fixed tests in jetty-servlets
* Fixed tests in jetty-proxy
* more test fixes
* Fixed head handling
reverted unnecessary changes
Improved reason handling
WIP on fully async error handling.
Simplified HttpChannelState state machines to allow for async actions
during completing
more WIP on fully async error handling.
sendError and completion are not both non-blocking, without using
a startAsync operation. However we are lacking unit tests that actually
exercise those code paths.
* Simplified name of states
Added test for async completion
* Cleanups and javadoc
* Cleanups and javadoc
* remove snake case
* feedback from review
* Write error page into fixed pooled buffer
Use the response to get/release a pooled buffer into which the error
page can be written. Make it a fixed sized buffer and if it overflows
then no error page is generated (first overflow turns off showstacks
to save space).
The ErrorHandler badly needs to be refactored, but we cannot change
API in jetty-9
