When `vim.diagnostic.set()` is called, the diagnostics passed to it are
added to the diagnostic cache. `set()` then calls `show()` and passes
those diagnostics along exactly as they were given to `set()`. However,
we sometimes want to do some kind of post-processing on diagnostics when
they come out of the cache, e.g. clamping line numbers. By forwarding
the diagnostics to `show()` verbatim, `set()` skips this post-processing
which can cause other bugs downstream.
Instead of passing the diagnostics directly, make the `show()` call from
within `set()` retrieve diagnostics from the cache. In general, all
diagnostics operations should follow the pattern of "producers put
things in the cache" and "consumers get things out of the cache" and
this change better adheres to that pattern.
This allows users to hook into diagnostic events with finer granularity
(e.g. per-buffer or file).
BREAKING CHANGE: DiagnosticsChanged and LspDiagnosticsChanged user
autocommands are removed.
Previously, the built-in language server client checked if the first
argument of cmd was executable via vim.fn.executable. This ignores PATH
injected via cmd_env. Instead, we now start the client via uv.spawn, and
handle the failure mode, reporting the error back to the user.

Floating windows opened by `goto_next` and `goto_prev` should not be
focused when repeating the `goto_` function. The float can still be
focused by calling `open_float` with `scope = "cursor"`.

Diagnostic producers can send diagnostics for buffers that are not
loaded, for which we cannot retrieve the line count to clamp line
numbers. This means that some diagnostics in the quickfix list could be
line-clamped and others not. The quickfix list can already handle line
numbers past the end of the buffer (i.e. it *already* clamps line
numbers) so just use the "raw" diagnostic positions sent from the
producer.
04bfd20bb introduced a subtle bug where using 0 as the buffer number in
the diagnostic cache resets the cache for the current buffer. This
happens because we were not checking to see if the _resolved_ buffer
number already existed in the cache; rather, when the __index metamethod
was called we assumed the index did not exist so we set its value to an
empty table. The fix for this is to check `rawget()` for the resolved
buffer number to see if the index already exists.
However, the reason this bug was introduced in the first place was
because we are simply being too clever by allowing a 0 buffer number as
the index which is automatically resolved to a real buffer number.
In the interest of minimizing metatable magic, remove this "feature" by
requiring the buffer number index to always be a valid buffer. This
ensures that the __index metamethod is only ever called for non-existing
buffers (which is what we wanted originally) as well as reduces some of
the cognitive overhead for understanding how the diagnostic cache works.
The tradeoff is that all public API functions must now resolve 0 buffer
numbers to the current buffer number.
vim-patch:8.2.3627: difficult to know where the text starts in a window
Problem: difficult to know where the text starts in a window. (Sergey
Vlasov)
Solution: Add the "textoff" entry in the result of getwininfo().
(closesvim/vim#9163)
cdf5fdb294
Fix indent in Test_getbufwintabinfo().
Errors were being caused by invalid buffers being kept around in
diagnostic_cache, so add a metatable to diagnostic_cache which attaches
to new buffers in the cache, removing them after they are invalidated.
Closes#16391.

The current 'clamp_line_numbers' implementation modifies diagnostics in
place, which can have adverse downstream side effects. Before clamping
line numbers, make a copy of the diagnostic. This commit also merges the
'clamp_line_numbers' method into a new 'get_diagnostics' local function
which also implements the more general "get" method. The public
'vim.diagnostic.get()' API now just uses this function (without
clamping). This has the added benefit that other internal API functions
that need to use get() no longer have to go through vim.validate.
Finally, reorganize the source code a bit by grouping all of the data
structures together near the top of the file.
Problem: getcwd() is unclear about how 'autochdir' is used.
Solution: Update the help for getcwd(). Without any arguments always return
the actual current directory. (closesvim/vim#9142)

If the quickfixlist item doesn't contain a column it is reported as 0.
Rather than using a nil value in such a case (which breaks diagnostics
elsewhere), just keep the 0 value.
Problem: No event is triggered when closing a window.
Solution: Add the WinClosed event. (Naohiro Ono, closesvim/vim#9110)

Nvim has already implemented this feature, so this only changes tests
and docs.
the prior signature did not assume an active language client
this function can now be used directly by passing an offset encoding
defaults to utf-16 (standard for LSP)
