Change implementation to compare sequences of bytes instead of C
strings.
The former implementation would return "false positives" in these cases:
"\0a" and "\0b": C strings are NUL-terminated, so it would compare two
empty strings.
"a" and "ab": If both strings aren't the same length, it would
compare only up to the length of the shorter one.
Fixes#5046.
API functions exposed via msgpack-rpc now fall into two categories:
- async functions, which are executed as soon as the request is parsed
- sync functions, which are invoked in nvim main loop when processing the
`K_EVENT special key
Only a few functions which can be safely executed in any context are marked as
async.
We already use wrappers for allocation, the new `xfree` function is the
equivalent for deallocation and provides a way to fully replace the malloc
implementation used by Neovim.
Since all API functions now run immediately after a msgpack-rpc request is
parsed by libuv callbacks, a mechanism was added to override this behavior and
allow certain functions to run in Nvim main loop.
The mechanism is simple: Any API function tagged with the FUNC_ATTR_DEFERRED (a
"dummy" attribute only used by msgpack-gen.lua) will be called when Nvim main
loop receives a K_EVENT key.
To implement this mechanism it was necessary some restructuration on the
msgpack-rpc modules, especially in the msgpack-gen.lua script.
Introducing the concept of providers: co-processes that talk with the editor
through the remote API and provide implementation for one or more core
services.
The `provider_register` function and it's API wrapper can be used by channels
that want to self-register as a service provider.
Some old builtin vim features will be re-implemented as providers. The
`provider_has_feature` function is used to check if a provider
implementing a certain feature is available(It will be called by the `has`
vimscript function to check for features in a vim-compatible way)
This implements the provider module without exposing any extension points, which
will be done in future commits.
This module will be used to implement remote management of objects through the
API. Object types to be registered must have a `uint64_t` field named 'handle'.
The map_* declarations and definitions are now created by a macro invocation
with a key type parameter. Also refactored server module to use the updated
version.
- Move `Map` structure definition to `map_defs.h`
- Use `KHASH_DECLARE` on map_defs.h to declare khash function prototypes.
- Redefine `map_foreach` into a macro
- Refactor server.c module to use the new `map_foreach` macro.
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.
