- Remove all *_set_defer methods and the 'defer' flag from rstream/jobs
- Added {signal,rstream,job}_event_source functions. Each return a pointer that
represent the event source for the object in question(For signals, a static
pointer is returned)
- Added a 'source' field to the Event struct, which is set to the appropriate
value by the code that created the event.
- Added a 'sources' parameter to `event_poll`. It should point to a
NULL-terminated array of event sources that will be used to decide which
events should be processed immediately
- Added a 'source_override' parameter to `rstream_new`. This was required to use
jobs as event sources of RStream instances(When "focusing" on a job, for
example).
- Extracted `process_from` static function from `event_process`.
- Remove 'defer' parameter from `event_process`, which now operates only on
deferred events.
- Refactor `channel_send_call` to use the new lock mechanism
What changed in a single sentence: Code that calls `event_poll` have to specify
which event sources should NOT be deferred. This change was necessary for a
number of reasons:
- To fix a bug where due to race conditions, a client request
could end in the deferred queue in the middle of a `channel_send_call`
invocation, resulting in a deadlock since the client process would never
receive a response, and channel_send_call would never return because
the client would still be waiting for the response.
- To handle "event locking" correctly in recursive `channel_send_call`
invocations when the frames are waiting for responses from different
clients. Not much of an issue now since there's only a python client, but
could break things later.
- To simplify the process of implementing synchronous functions that depend on
asynchronous events.

`-Wstrict-prototypes` warn if a function is declared or defined without
specifying the argument types.
This warning disallow function prototypes with empty parameter list.
In C, a function declared with an empty parameter list accepts an
arbitrary number of arguments when being called. This is for historic
reasons; originally, C functions didn't have prototypes, as C evolved
from B, a typeless language. When prototypes were added, the original
typeless declarations were left in the language for backwards
compatibility.
Instead we should provide `void` in argument list to state
that function doesn't have arguments.
Also this warning disallow declaring type of the parameters after the
parentheses because Neovim header generator produce no declarations for
old-stlyle prototypes: it expects to find `{` after prototype.

This was done to generalize the usage of `event_poll`, which will now return
`true` only if a event has been processed/deferred before the timeout(if not
-1).
To do that, the `input_ready` calls have been extracted to the input.c
module(the `event_poll` call has been surrounded by `input_ready` calls,
resulting in the same behavior).
The `input_start`/`input_stop` calls still present in `event_poll` are
temporary: When the API becomes the only way to read user input, it will no
longer be necessary to start/stop the input stream.

To make it possible reuse `event_poll` recursively and in other blocking
function calls, this changes how deferred/immediate events are processed:
- There are two queues in event.c, one for immediate events and another for
deferred events. The queue used when pushing/processing events is determined
with boolean arguments passed to `event_push`/`event_process` respectively.
- Events pushed to the immediate queue are processed inside `event_poll` but
after the `uv_run` call. This is required because libuv event loop does not
support recursion, and processing events may result in other `event_poll`
calls.
- Events pushed to the deferred queue are processed later by calling
`event_process(true)`. This is required to "trick" vim into treating all
asynchronous events as special keypresses, which is the least obtrusive
way of introducing asynchronicity into the editor.
- RStream instances will now forward the `defer` flag to the `event_push` call.

- The 'stripdecls.py' script replaces declarations in all headers by includes to
generated headers.
`ag '#\s*if(?!ndef NEOVIM_).*((?!#\s*endif).*\n)*#ifdef INCLUDE_GENERATED'`
was used for this.
- Add and integrate gendeclarations.lua into the build system to generate the
required includes.
- Add -Wno-unused-function
- Made a bunch of old-style definitions ANSI
This adds a requirement: all type and structure definitions must be present
before INCLUDE_GENERATED_DECLARATIONS-protected include.
Warning: mch_expandpath (path.h.generated.h) was moved manually. So far it is
the only exception.

Uses a perl script to move it (scripts/movedocs.pl)
|
| |
|
|
| |
Prepend 'nvim/' in all project-local (non-system) includes.
|
|
|
Move files from src/ to src/nvim/.
- src/nvim/ becomes the new root dir for nvim executable sources.
- src/libnvim/ is planned to become root dir of the neovim library.
