fix#11753close#11781
The virtualenv troubleshooting in the Python provider health checks is
supposed to help the user determine whether running Python from Neovim
(as in `system('python')` or `system(exepath('python'))`) will use the
correct executable when a virtualenv is active. Currently however, it
issues spurious warnings in legitimate setups, and conversely, fails to
warn about potentially problematic ones.
See https://github.com/neovim/neovim/issues/11753#issuecomment-578715584
for a more detailed analysis, but at a high level, this is due to two
things:
- the virtualenv check is part of the Python provider check defined in
`s:check_python`, which uses a roundabout and sometimes erroneous way of
determining the Python executable
- more generally, it shouldn't be part of the provider check at all,
because it's not really related to the Python *provider*, i.e. the
Python executable which can communicate with Neovim via `pynvim`, but to
the Python the user is editing source files for, which typically
shouldn't even have `pynvim` installed
This patch reimplements the virtualenv check and factors it out into its
own separate function, which is however still kept in
`health/provider.vim` alongside the rest of the Python troubleshooting,
since troubleshooting all Python-related stuff in one place is probably
a good idea in order to alleviate any potential confusion (e.g. users
who run only provider checks might be left wondering whether their
virtualenv Python was properly detected if the report only shows their
global Python as the provider used by Neovim).
The old `:Man` implementation would take either the word under
the cursor, or the argument passed in, and load that as a man page.
Since we now use 'tagfunc' and look for all relevant man-pages, if
your system has several (i.e. same name, different sections), we return
several, giving the user an option.
This works for most tag commands except `:tjump`, which will
fail if there's multiple tags to choose from. This just happens to
be what the cscope code uses (it actually attempts to prompt the
user, but this fails).
test_registers.vim can fail even if a clipboard manager is running.
If a clipboard manager is not running, this test always fails with xclip.
Use xsel as a workaround.
https://github.com/astrand/xclip/issues/20 suggests closing stdout
when sending input via stdin.
Environment
- Ubuntu Xenial
- Vim 7.4 (any app with broken clipboard code will do)
- Neovim nightly
Steps to reproduce:
0. Start the clipboard manager.
1. Open a file in Vim on Linux.
Vim should have +clipboard enabled.
'set clipboard='
2. Yank some text to the clipboard register.
3. Quit Vim.
4. Run 'cd /path/to/neovim/repo/'
5. Run 'make oldtest'.
Do not run any individual tests.
They likely pass with or without this fix.
Before fix: test_registers.vim can fail.
After fix: test_registers.vim always passes.

This addresses a minor quality problem with the recent `'tagfunc'`
changes for `man.vim` (see [link]).
Currently, with the cursor on a parenthese, hitting `K` will jump us to
the man page of the next mentioned entry, instead of the one to which
the parenthese (or section number) belongs.
```
pcrepattern(3), terminfo(5), glob(7), regex(7).
e.g. ^ e.g. ^
```
Adding the parentheses to `'iskeyword'` means we correctly handle these cases too.

Mainly configuration and RPC infrastructure can be considered "done". Specific requests and their callbacks will be improved later (and also served by plugins). There are also some TODO:s for the client itself, like incremental updates.

Problem: If spellfile is missing, then "set spell" in modeline/sandbox
fails with a non-obvious error.
Solution: Check for sandbox early and give a meaningful error.
Fixes#11359
Test case:
# test.latex has `% vim: set spelllang=hu:`
# no spell file for `hu` yet!
nvim -u NORC --cmd 'autocmd FileType tex setlocal spell' --cmd 'set modeline' test.latex
Before:
No spell file for "hu" in utf-8

fixes#11293
In order to find if there was already an open man page, the :Man command
would cycle through each window to see if &ft=='man'. This triggers
autocmds, e.g. BufEnter, unnecessarily and can have unexpected
side-effects.
Change the logic to check each window's ft without switching to it
unless it is actually a man window.

The Python provider was special (via [1]), and would continue to do
checks with `0` being set explicitly even.
This was fixed in #11044 (45447e3b6), ref: #11040.
This extends it to use the same method with all providers.

This reverts part of ade88fe4c [1].
This is required for `let g:python3_host_prog = 'python'` etc, where it
should get picked up from PATH.
Without this it would show:
```
- INFO: pyenv: Path: /home/user/.pyenv/libexec/pyenv
- INFO: pyenv: Root: /home/user/.pyenv
- INFO: Using: g:python3_host_prog = "python"
- ERROR: "python" was not found.
- INFO: Executable: Not found
- ERROR: Detected pip upgrade failure: Python executable can import "pynvim" but not "neovim": python
- ADVICE:
- Use that Python version to reinstall "pynvim" and optionally "neovim".
pip3 uninstall pynvim neovim
pip3 install pynvim
pip3 install neovim # only if needed by third-party software
```
Note that it additionally causes a weird error
("Detected pip upgrade failure"), due to `s:check_bin` emptying
`python_exe` (because the non-absolute file not being readable), and
`provider#pythonx#DetectByModule('pynvim', a:version)` from 75593e6fce
then just getting the value from the host var again (without actual
checks).
This is implicitly fixed via this patch now (because it is skipped), but
could need some improvement in this regard probably.
With this patch it resolves it (for a virtualenv where pynvim is not
made available intentionally):
```

Note: this appears to display the error twice via "Output:" and
"Stderr:".

Instead of deciding provider status in eval_has_provider, move the
decision to the provider Vim scripts.
Previously, provider loading worked as follows:
1. eval_has_provider() verified provider availability by searching for
the provider#providername#Call function and cached this verificaion as a static
variable for some providers
2. providers short-circuited on loading to prevent the definition of the
Call function (with the exception of the node provider that did not)
This commit changes the expected interface between nvim and its
providers to facilitate provider reloading, by splitting the
verification of the provider from the availability of the Call function.
eval_has_provider() now checks for a provider#providername#enabled
variable. It is up to the provider script to set this to 0 or 1
accordingly. eval_call_provider() remains unchanged.
All providers hosting a Call function were updated to respect this.
The clipboard provider now has a Reload function to reload the
provider.
