Problem: Dead assignment @ 7711.
http://neovim.org/doc/reports/clang/report-835eb6.html#EndPath
Diagnostic: Harmless issue.
Rationale : `scol` is only used within `FOR_ALL_TABS` body, which
assigns another value to `scol` at the beginning of each
iteration. If `FOR_ALL_TABS` body would not execute (no
tabs) nothing harmful would happen, as code following
`FOR_ALL_TABS` doesn't use `scol`.
Resolution: Remove.
Problem: Dead assigment.
http://neovim.org/doc/reports/clang/report-7362ba.html#EndPath
Diagnostic: Harmless issue.
Rationale : `boguscols` is in fact unread by downstream code.
Resolution: Comment out. This is preferred here over just removing the
line because involved logic is complex, and future readers
of this code could find this extra knowledge useful to
understand what the code is doing.
Problem: Dead initialization @ 3477.
http://neovim.org/doc/reports/clang/report-94b736.html#EndPath
Diagnostic: Harmless issue.
Rationale : `len` is assigned a new value just some lines below. So,
this just seems something due to old-style variable
declarations.
Resolution: We could just remove initialization, but prefer moving
declaration down to point of initialization.
Problem: Assigned value is garbage or undefined @ 187.
http://neovim.org/doc/reports/clang/report-7b7d61.html#EndPath.
Diagnostic: False positive.
Rationale : `colonp`, must be `>= modep, or null` by `vim_strchr`
postcondition. At this point we also it's not null and it's
not equal to `modep`, by previous code. So, it must be
`> modep`.
Resolution: Assert `colonp > modep`.
It is currently possible for a client to send a response that doesn't match the
current server->client request(at the top of the stack). This commit fixes that
by delaying notifications to until the first `channel_send_call` invocation
returns.
Also remove the "call stack" size check, vim will already break if the call
stack goes too deep.
The options_spec.lua suite has one purpose: Check if the :options commands will
throw any exception(:options is implemented by $VIMRUNTIME/optwin.vim). For this
it is best to use the `vim_command` API function since it will automatically
catch exceptions and forward them via msgpack-rpc.
Also, the option window seems to affect other tests, so call `restart` in the
teardown hook.
If you aren't just building everything into build/, then the functional
tests fail because they can't find the nvim executable. Let's pass in
the location of the nvim executable, and set NVIM_PRG environment
variable accordingly.
Remove build warning:
The target name "test" is reserved or not valid for certain CMake
features, such as generator expressions, and may result in undefined
behavior.
