This evades the tempfile problem (unless of course one manually adds
redirects to the shell commandline, which some plugins seem to do, e.g.:
vim-easytags).
This uses the provider/scripting infrastructure to reintroduce python support
through the msgpack-rpc API.
A new 'initpython' option was added, and it must be set to a command that will
bootstrap the python provider the first time it's needed.
This uses the provider module infrastructure to implement common code for
vimscript commands/functions that need to communicate with external
interpreters, eg: pydo, rubydo, pyfile, rubyfile, etc.
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.
Should be better than gettimeofday() since libuv uses higher resolution
clocks on most UNIX platforms. Libuv also tries to use monotonic clocks,
kernel bugs notwithstanding, which is another win over gettimeofday().
Necessary for Windows, which doesn't have gettimeofday(). In vanilla vim,
Windows uses QueryPerformanceCounter, which is the correct primitive for
this sort of things, but that was removed when slimming up the codebase.
Libuv uses QueryPerformanceCounter to implement uv_hrtime() on Windows so
the behaviour of vim profiling on Windows should now be the same.
The behaviour on Linux should be different (better) though, libuv uses more
accurate primitives than gettimeofday().
Other misc. changes:
- Added function attributes where relevant (const, pure, ...)
- Convert functions to receive scalars: Now that proftime_T is always a
(uint64_t) scalar (and not a struct), it's clearer to convert the
functions to receive it as such instead of a pointer to a scalar.
- Extract profiling funcs to profile.c: make everything clearer and reduces
the size of the "catch-all" ex_cmds2.c
- Add profile.{c,h} to clint and -Wconv:
- Don't use sprintf, use snprintf
- Don't use long, use int16_t/int32_t/...
Though this module is relatively small it has very clear boundaries.
The last argument for extracting `tempfile` was the errors which I got
when I was writing unittests for it: `cimport './src/nvim/fileio.h'`
does not work for some reason.
- temp_count is uint32_t now instead of long because it supposed to be
at most 999999999 (comment on line 5227) temporary files. The most
probably it was a long for compatibility with systems where int is
16-bit.
- Use "nvim" as prefix for temp folder name instead of "v"
- Remove unused parameter from vim_tempname
`-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.
- use return value instead of open_req.result
- libuv uv_fs_open() returns `-errno` instead of always -1
- libuv always sets open_req.result to the return value, _except_ for OOM
where it only sets the return value. So always use the return value.
- replace calls to mch_open macro.
- update call sites expecting -1 error
This macro is used to append an element to a growable array. It replaces this
common idiom:
ga_grow(&ga, 1);
((item_type *)ga.ga_data)[ga.ga_len] = item;
++ga.ga_len;
The old mch_libcall was removed from neovim. This is a partial
reimplementation on top of libuv. It doesn't catch exceptions (windows) nor
signals (unix) though, so it's quite a bit more prone to crashing if the
loadable library throws an exception or crashes. Still, it should be fine
for well-behaved libraries. Requested by @Shougo.
This function is used to send RPC calls to clients. In contrast to
`channel_send_event`, this function will block until the client sends a
response(But it will continue processing requests from that client).
The RPC call stack has a maximum depth of 20.
