This also makes shada reading slightly faster due to avoiding
some copying and allocation.
Use keysets to drive decoding of msgpack maps for shada entries.
`FileDescriptor` is already a wrapper around an fd and a buffer.
By allowing to just use the buffer without an fd, it can
already handle in-memory reads.
Specifically, functions that are run in the context of the test runner
are put in module `test/testutil.lua` while the functions that are run
in the context of the test session are put in
`test/functional/testnvim.lua`.
Closes https://github.com/neovim/neovim/issues/27004.
`nvim_(get|set)_option_value` pick the current buffer / window by default for buffer-local/window-local (but not global-local) options. So specifying `buf = 0` or `win = 0` in opts is unnecessary for those options. This PR removes those to reduce code clutter.
Extend the capabilities of is_os to detect more platforms such as
freebsd and openbsd. Also remove `iswin()` helper function as it can be
replaced by `is_os("win")`.
This is essentially a convenience wrapper around the `pending()`
function, similar to `skip_fragile()` but more general-purpose.
Also remove `pending_win32` function as it can be replaced by
`skip(iswin())`.
Problem: The do_set() function is much too long.
Solution: Move setting of a string option to a separate function.

Cherry-pick some tests from Vim patch 8.2.0540.
Problem:
Dirs "config", "packaging", and "third-party" are all closely related
but this is not obvious from the layout. This adds friction for new
contributors.
Solution:
- rename config/ to cmake.config/
- rename test/config/ to test/cmakeconfig/ because it is used in Lua
tests: require('test.cmakeconfig.paths').
- rename packaging/ to cmake.packaging/
- rename third-party/ to cmake.deps/ (parallel with .deps/)
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- `redir_exec` is obsolete, but it keeps getting used in new tests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`.
As Strings and Blobs are encoded as msgpack BINs, the current ShaDa
implementation will restore global Blob variables as Strings (or msgpack
special dicts if they contain NULs).
Encode an additional element with Blob globals to differentiate them
from Strings so that we can restore them with the correct type.
Adjust variables_spec.lua's autotest() to also check for proper type.
If set the number of history saves is 0, assertions fail when inserting an entry on exit.
Dont insert an entry when the number of saves is 0 fixes the issue.
fixes#11497
Since 8b8ecf4, the shada module loads files in the jumplist to properly
clear duplicates. This can trigger some autocommands, which in turn
saves and restores search and substitute patterns, freeing the previous
strings in "spats" which are held in "wms" as well (heap-use-after-free).
To avoid this, initialize the jumplist in "wms" before search patterns.
Problems:
- In two places in shada_read_when_writing() memory just was not freed. Both
places were verified to cause test failures.
- Numbered marks got assigned incorrect (off-by-one compared to position in the
array) numbers in replace_numbered_mark.
- It was possible to have non-continuously populated array of numbered marks
which messed up code for merging them.
(Note about tests: marks with additional data are always compared different when
merging, that caused some confusion regarding why test did not work the way
I expected.)
