Add multiprocessing= argument to attach() and enable_attach().
Refactor common code in attach() and enable_attach().
Remove broken legacy multiproc implementation.
Ensure that all captured output is reported to the IDE before reporting process exit.
Correctly report "process", "exited", and "terminated" events for "noDebug".
Don't treat partial message reads as fatal error.
Switch test_nodebug to "internalConsole", so that it can properly produce "output" events.
Expect failure response from "setBreakpoints" in test_nodebug.
Fix environment dict being shared between subsequent test runs, causing spurious enable_attach() in debuggee.
Fix ordering in debuggee and adapter cleanup in debug.Session.
Fix launcher.py on Python 2.7
Move docstrings to top-level package, and update them to reflect the current behavior.
Remove unused code in ptvsd.common.log.
Move sys.path/prefix/site_packages logging into ptvsd.common.log, and log it from adapter and server to the same level of detail as the tests.
Fix injected code snipped for attach-by-PID.
Fix some Unicode issues in adapter and tests.
Refactor Timeline, debug.Session, and start methods.
* noDebug mode support
* Ensure we get the debuggee pid on launch
* Fix state change bug
* Tweaking pid retreival
* Use makefile and simplify pid retreival
* Addressing comments
* Run formatter
* Change name common.socket to common.sockets
* Add some timeouts
* Fix linter
Encode environment variables on Python 2.
Fix#1659: Debuggee output breaks adapter with "internalConsole"
Use os.devnull for debuggee stdin, and redirect debuggee stdout to stderr.
Capture output for debuggee stdout and stderr, generate DAP "output" events from it, and suppress the same coming from the debug server.
* Initial fix for launch
* Minor fixes
* Succesful launch tests
* More launch test fixes
* Some bit of cleanup
* Fix linter
* More cleanup
* Attach using import
* Fix circular importing
* Support attach via command line
* Backchannel and Other test fixes
* Linter fix
* Python path fix in test
* Fix lint after rebase
* Support exitCode in tests
* More fixes after rebase
* Fix expected exit code
* Remove changes to MessageDict __call__
* Remove hold subprocess event
Separate message parsing and message handling into separate threads.
Remove nested message handling in request handlers via `yield`, since it is incompatible with the new split model, and replace it with NO_RESPONSE and Request.respond() to defer responses until later.
Change Message.cant_handle() and Message.isnt_valid() to respond to the request and return the exception, instead of raising it, to accommodate NO_RESPONSE scenarios where a failure needs to be reported later.
Fix#1678: Do not rely on "processId" being returned by "runInTerminal" request
Extract debuggee PID from the "process" event sent by the debug server.
Fix#1679: "exited" event sometimes reports "exitCode": null
Report it as -1 if it cannot be retrieved from the debuggee process.
Fix#1680: Fatal errors in message loop do not fail fast
os._exit() immediately if a fatal error occurs in message parsing or message handling background threads.
* Remove wrapper and in-proc support code
* Fixing up multiproc patching
* Address comments
* Import cleanup
* More cleanup
* Remove loopback fast path
* Disable IDE disconnect unpause-ing
* Add missing file to do not trace
Fix#1605: Debuggee process lifetime management
Mitigate #1637: log.exception() doesn't capture the full stack
Handle "launch" request, parse and validate the debug configuration, and spawn the debuggee process with debug server.
Track debuggee process and its subprocesses, and kill them as needed.
Refactor Singleton and ThreadSafeSingleton to allow for easier synchronization between IDE and server message handlers without excessive locking.
Fix various corner cases and race conditions in disconnect scenarios.
Make log.exception() log the calling stack, not just the exception stack.
Add JSON property validation to MessageDict.
Add --log-stderr switch to the server to enable full logging to stderr.
Add --cls switch to the adapter to reset terminal before logging anything (for convenience when debugging it).
Add some printf-debugging helpers.
Add ptvsd.adapter.contract module as a single access point for capabilities and other immutable IDE and server metadata.
Change the semantics of Channels.server() to enable checks for disconnected server.
Fix "disconnect" and "terminate" handling when not connected to debug server.
Do best-effort handling of "ptvsd_systemInfo" if not connected to debug server.
Add long_tmpdir fixture, that always supplies a long rather than short path name on Windows.
Use long_tmpdir in the implementation of @pyfile, and in all tests that use tmpdir to generate code.
