This is necessary to keep events in the same order received from the OS.

Since pty events are queued, it is possible that the reads will be reordered.
Example scenario:
In the terminal you have output combined from stdout and stderr. A program
generates output, first you have some output on stdout, then output on stderr,
output on stdout, output on stderr,... The whole output should be interleaved
from both streams.
Each output generates a read_event and they are placed in the same queue. If the
queue is processed, the first read_event will send the whole stdout output to
the terminal (on_job_output() consumes the whole buffer). The next read_event is
similar for stderr. The remaining read events do nothing because now both
RBuffer are already empty. So the terminal would show first the stdout output
and after that the stderr output.
This commit fixes the problem by disabling stderr stream in pty processes.
That's ok because they all represent the same stream(duplicate file
descriptors), plus one stream is simpler to deal with.

- Improve the implementation of deferred/immediate events.
- Use the new queue module to change how/when events are queued/processed by
giving a private queue to each emitter.
- Immediate events(which only exist to break uv_run recursion) are now
represented in the `loop->fast_events` queue.
- Events pushed to child queues are propagated to the event loop main queue and
processed as K_EVENT keys.

Change the API so that it is passed to {uv,pty}_process_init instead of
`process_spawn`.

- Declare poll timer in Loop structure instead of a loop_poll_events local
variable.
- Move deferred event management to input.c

- Add missing call when the stream is a file
- NULL check because it is possible to call rstream_start with the callback set
to NULL.

- New libuv/pty process abstraction with simplified API and no globals.
- Remove nvim/os/job*. Jobs are now a concept that apply only to programs
spawned by vimscript job* functions.
- Refactor shell.c/channel.c to use the new module, which brings a number of
advantages:
- Simplified API, less code
- No slots in the user job table are used
- Not possible to acidentally receive data from vimscript
- Implement job table in eval.c, which is now a hash table with unilimited job
slots and unique job ids.

- Move event loop code into event/socket
- Reimplement server.c on top of the new SocketWatcher class
- Adapt msgpack_rpc/channel.c

- Simplify RStream/WStream API and make it more consistent with libuv.
- Move into the event loop layer(event subdirectory)
- Remove uv_helpers module.
- Simplify job/process internal modules/API.
- Unify RStream and WStream into a single structure. This is necessary because
libuv streams can be readable and writable at the same time(and because the
uv_helpers.c hack to associate multiple streams with libuv handle was removed)
- Make struct definition public, allowing more flexible/simple memory
management by users of the module.
- Adapt channel/job modules to cope with the changes.
|
|

- Add event loop abstraction module under src/nvim/event. The
src/nvim/event/loop module replaces src/nvim/os/event
- Remove direct dependency on libuv signal/timer API and use the new abstraction
instead.
- Replace all references to uv_default_loop() by &loop.uv, a new global variable
that wraps libuv main event loop but allows the event loop functions to be
reused in other contexts.
