Problem:
Piping NodeJS output into Neovim makes the editor unusable.
This happens because NodeJS changes the tty state on exit after
Nvim calls uv_tty_set_mode(). (May not always happen due to race
condition.)
This should have been fixed by 4ba5b4a864#13084. But some
commands and functions (:sleep, system(), …) call ui_flush()
internally, in particular the first tui_mode_change() is called before
the end of startup.
Steps to reproduce:
1. node -e "setTimeout(()=>{console.log('test')}, 1000)" | nvim -u NORC +"sleep 500m" -
2. The cursor key letters just overwrite the editor screen, and CTRL+C exits.
Solution:
Skip pending_mode_update during startup.
Note: Delaying ui_flush() entirely could be a more general solution
(emit a new UI event on VimEnter?). But "remote/coprocess TUI" #18375
could make all of this moot anyway.
Fixes#18470
Problem:
The release script bundles a system library (CoreServices) that was
added in #18294, which leads to errors on M1 since the architecture is
different from the Github runner.
Solution:
Skip CoreServices when bundling the libraries (as was done for the
CoreFoundation library that #18294 replaced with CoreServices).
Problem:
1. CI logs have too many (40+) logs mentioning SIGHUP:
```
WRN 2022-06-18T16:05:47.075 T3568.22499.0/c deadly_signal:177: got signal 1 (SIGHUP)
WRN 2022-06-18T16:05:47.273 T3569.91095.0/c deadly_signal:177: got signal 1 (SIGHUP)
WRN 2022-06-18T16:05:47.651 T3570.59545.0/c deadly_signal:177: got signal 1 (SIGHUP)
```
2. TS parser test still sometimes fails on BSD CI.
3. remote_spec test fails too often.
Solution:
1. Log deadly signals at INFO level. It hasn't been helpful in CI, and
for local troubleshooting it's reasonable to adjust the loglevel as
needed.
2. Adjust the TS parser test again. ref #18911
3. Skip the remote_spec test. The `--remote` feature was merged before
it was fully formed and needs to be revisited.
luacheck and clint are the most important, and they are bundled.
The others are nice-to-have, and not always available (and not bundled),
so make them optional. This allows the "lint" target to function as
a convenient and low-hassle handle for contributors.
We still get the full power of lint in CI.
TODO: bundle uncrustify (and then set it as required for "lint")?
Problem:
Coverity reports use after free:
*** CID 352784: Memory - illegal accesses (USE_AFTER_FREE)

1509 }
1510 }

1512 /// Enter a new current buffer.
1513 /// Old curbuf must have been abandoned already! This also means "curbuf" may
Solution:
Change terminal_destroy and terminal_close to set caller storage to NULL,
similar to XFREE_CLEAR. This aligns with the pattern found already in:
terminal_destroy e897ccad3e
term_delayed_free 3e59c1e20d
Problem:
If startup finishes (starting=false) before the logger ever happens to
see a v:servername, we're stuck with the "?.<PID>" fallback name
forever.
Solution:
Drop the `starting` condition. Discard the "?.<PID>" fallback after
using it for the current log message. So logging will always check
v:servername next time.
If `use_rgb` was false, we would attempt to set the `cterm_bg_color` to the
variable `bg`, which is only retrieved from `bg` and `background` keys, not
`ctermbg`. Same for `fg`. This means the values would be `-1` (the default,
un-got value) and we'd always set the returned values to `0`.
My understanding is `fg/bg` is always "gui" values, so instead we should be
using `ctermbg` when needed.
Nb: when looking around I think this function is currently *always* called with
`use_rgb = true`.
Fixes#18980
- 831fa45ad8 is related but this doesn't regress that
- The `cterm_normal_fg_color != ae.cterm_fg_color` comparison is originally
carried from patch to patch starting all the way back in 29bc6dfabd where it
was avoiding setting a HL attr. But `hlattrs2dict()` now is just
informational.
The current emulation script enters Insert mode much too frequently.
Using only BufWinEnter seems to be a closer simulation.
Also add a few more mappings.
Steps to reproduce:
1. setting `vim.highlight.on_yank`
```
vim.api.nvim_create_autocmd({ "TextYankPost" }, {
pattern = { "*" },
callback = function()
vim.highlight.on_yank({ timeout = 200 })
end,
})
```
2. repeat typing `yeye` ...
3. causes the following error.
```

Problem:
- Unix sockets are created in random /tmp dirs.
- /tmp is messy, unclear when OSes actually clear it.
- The generated paths are very ugly. This adds friction to reasoning
about which paths belong to which Nvim instances.
- No way to provide a human-friendly way to identify Nvim instances in
logs or server addresses.
Solution:
- Store unix sockets in stdpath('state')
- Allow --listen "name" and serverstart("name") to given a name (which
is appended to a generated path).
TODO:
- is stdpath(state) the right place?
Problem:
1. Log messages (especially in CI) are hard to correlate with tests.
2. Since b353a5c05f#11886, dumplog() prints the logs next to test
failures. This is noisy and gets in the way of the test results.
Solution:
1. Associate an incrementing id with each test and include it in log
messages.
- FUTURE: add v:name so Nvim instances can be formally "named"?
2. Mention "child" in log messages if the current Nvim is a child (based
on the presence of $NVIM).

drawback: tracing memory errors with ASAN is less accurate for arena
allocated memory.
Therefore, to start with it is being used for Object types around
serialization/deserialization exclusively. This is going to have
a large impact especially when TUI is refactored as a co-prosess
as all UI events will be serialized and deserialized by nvim itself.
Problem: Not all modifiers supported for :options.
Solution: Use all cmdmod.split flags. (closesvim/vim#4401)
