- Add a job control module for spawning and controlling co-processes
- Add three vimscript functions for interfacing with the module
- Use dedicated header files for typedefs/structs in event/job modules
- Add a new macro to klist.h: kl_empty()
The whole point of abstract data structures is to avoid reimplementing
common actions. The emptiness test seems to be such an action.
- Add a new function attribute to func_attr.h: FUNC_ATTR_UNUSED
Some of the many functions created by the macros in klist.h may end up not
being used. Unused functions cause compilation errors as we compile with
-Werror. To mark those functions as possibly unused we can use the
FUNC_ATTR_UNUSED now.
- Pass `Event` by value
`Event` is such a small struct that I don't think we should allocate heap space
and pass it by reference. Let's use the stack and memory cache in our favor
passing it by value.
By simpler cases I mean cases where the OOM error is not expected to be handled
by the caller of the function that calls `alloc`, `lalloc`, `xrealloc`,
`xmalloc`, `alloc_clear`, and `lalloc_clear`.
These are the functions that:
- Do not return an allocated buffer
- Have OOM as the only error condition
I took note of the functions that expect the caller to handle the OOM error and
will go through them to check all the callers that may be handling OOM error in
future commits.
I'm ignoring eval.c and ex_.c in this series of commits. eval.c will soon be
obsolete and I will deal with ex_.c in later PRs.
The last occurrence of `RealWaitForChar` was replaced by the `os_microdelay`
function. `mch_new_shellsize` had an empty body, so there seems to be no reason
for keeping it around
The environment variable USE_VALGRIND can be set to run tests with valgrind. If
VALGRIND_GDB is set, valgrind will start it's own gdbserver for remote
debugging with `target remote | vgdb`. USE_GDB can still be used, but it will
be ignored if USE_VALGRIND is set.
