"Pointer to local array 'sourcing_name_buf' is stored outside the scope
of this array. Such a pointer will become invalid."
False positive: `sourcing_name = save_sourcing_name` before returning
from this scope.

Solution:
This is a follow-up to the work done in
6c03601e3a.
There are valid situations where a `textDocument/codeAction` is returned
without a command, since a command in optional. For example from Metals,
the Scala language server when you get a code action to add a missing
import, it looks like this:
```json
Result: [
{
"title": "Import \u0027Instant\u0027 from package \u0027java.time\u0027",
"kind": "quickfix",
"diagnostics": [
{
"range": {
"start": {
"line": 6,
"character": 10
},
"end": {
"line": 6,
"character": 17
}
},
"severity": 1,
"source": "bloop",
"message": "not found: value Instant"
}
],
"edit": {
"changes": {
"file:///Users/ckipp/Documents/scala-workspace/sanity/src/main/scala/Thing.scala": [
{
"range": {
"start": {
"line": 6,
"character": 10
},
"end": {
"line": 6,
"character": 17
}
},
"newText": "Instant"
},
{
"range": {
"start": {
"line": 1,
"character": 0
},
"end": {
"line": 1,
"character": 0
}
},
"newText": "\nimport java.time.Instant\n"
}
]
}
}
}
]
```
This change just wraps the logic that grabs the command in a conditional
to skip it if there is no command.
diagnostic_lines() returns a table, so make the early exit condition an
empty table rather than 'nil'. This way, functions that use the input
from diagnostic_lines don't have to do a bunch of defensive nil checking
and can always assume they're operating on a table.
This function isn't compatible with including diagnostic sources when
"source" is "if_many" since it only has access to diagnostics for a
single line. Rather than having an inconsistent or incomplete interface,
make this function private. It is still exported as part of the module
for backward compatibility with vim.lsp.diagnostics, but it can
eventually be made into a local function.
* preserve fields from LSP diagnostics via adding a user_data table to the diagnostic, which can hold arbitrary data in addition to the lsp diagnostic information.
This fixes the handler signature and also prevents n+1 requests firing
if there are multiple clients.
(The first `prepareCallHierarchy` handler is called once per client,
each invocation used `buf_request` to make more requests using *all*
clients)
This is mostly motivated by https://github.com/neovim/neovim/issues/12326
Client side commands might need to access the original request
parameters.
Currently this is already possible by using closures with
`vim.lsp.buf_request`, but the global handlers so far couldn't access
the request parameters.
Some parts of LSP need to use cached diagnostics as sent from the LSP
server unmodified. Rather than fixing invalid line numbers when
diagnostics are first set, fix them when they are displayed to the user
(e.g. in show() or one of the get_next/get_prev family of functions).
Since the `State` is global, other scripts are unexpectedly affected during the
'inccommand' preview. This commit introduces a new flag for `do_cmdline`, in
order to ignore trailing '|'-separated commands only for the command invoking
the preview.
fix#8796, update #7494
Changes to the main Makefile:
- add `MAKEFILE_PATH` and `MAKEFILE_DIR` that are set with native commands
- add `NVIM_PRG`
- rename `BUILD_TYPE` to `CMAKE_GENERATOR` to align with CMake naming
- remove the misleading `BUILD_CMD` and use `BUILD_TOOL` instead
Add the following phony target to quickly test the changes
```make
debug-print:
@echo makefile path: $(MAKEFILE_PATH)
@echo makefile dir: $(MAKEFILE_DIR)
@echo build dir: $(BUILD_DIR)
@echo cmake generator tool: $(CMAKE_GENERATOR)
@echo build-tool: $(BUILD_TOOL)
@echo nvim-prg: $(NVIM_PRG)
```
* feat(diagnostic): add vim.diagnostic.match()
Provide vim.diagnostic.match() to generate a diagnostic from a string and
a Lua pattern.
* feat(diagnostic): add tolist() and fromlist()
Problem
- `redir_exec` is obsolete, but it keeps getting used in new tests
because people copy existing tests.
- Disadvantages of `redir_exec`:
- Captures extra junk before the actual error/message that we _want_ to test.
- Does not fail on error, unlike e.g. `command()`.
Solution
- Use new functions like `nvim_exec` and `pcall_err`.
