Port VimL's Blob type - vim-patch:8.1.{0735,0736,0738,0741,0742,0755,0756,0757,0765,0793,0797,0798,0802,1022,1023,1671},8.2.{0121,0184,0404,0521,0829,1473,1866,2712}
Problem:
13748512f6#15610 The no-colors codepath of the nvim.lua test output
handler does not handle nil, leading to weird symptoms if e.g. a test
has a syntax error:
test/busted/outputHandlers/nvim.lua:105: attempt to concatenate a nil value
Solution:
Coerce to string in no-colors handler.
Problem:
`buftype=help` occasionally propagates from help to man buffer. As a result the
next time you open help it opens in the man window, replacing the manpage.
Test case:
nvim -u NORC
:Man man
:set bt? " should print `buftype=nofile`
:help
<C-W><C-W><C-W>c " go back to :Man window and close it
:help " focus help window
:Man man " open window with manpage again
:set bt? " prints `buftype=help`
Solution:
- call s:set_options()
- man#read_page() (called by autocmd BufReadCmd man://*) should already do
this. But BufReadCmd doesn't fire for already-existing man:// buffers.
Fix#15650
Also includes some small relevant nearby non-Blob changes and typo
fixes.
Changes are included from:
- v8.1.0815
- v8.1.0846
- v8.1.1084
- v8.1.2326
- v8.2.1969
- d89682477c
- d09091d495
- 53f7fccc94
Note that it is not possible for msgpack_unpack_next() and
msgpack_unpacker_next() to return MSGPACK_UNPACK_EXTRA_BYTES, so it
should be fine to abort() on that.
Lua 5.1 doesn't support string hex escapes (\xXX) like VimL does (though
LuaJIT does), so convert them to decimal escapes (\DDD) in tests.
For example, implicitly converting a table to a string works in LuaJIT,
but needs to be done explicitly with tostring() in Lua 5.1.
This can cause issues when testing a non-JIT build if eq(), for example,
fails with a table argument. E.g: eq({}, {1}) will not print the details
of the assertion failure, but will instead print a less helpful "string
expected, got table" error.
These were issues that I found while porting that I fixed upstream. :^)
Very little of the patch can be exactly ported as we're a bit behind on
dependant patches (we also can't use the exact :for emsg, as we don't
support iterating over Strings yet), so just translate the fixes as best
as we can for now.
Include latest relevant doc changes from:
- v8.1.0815
- v8.2.2658
Fixes remove() copying one extra byte after the end of a Blob's buffer.
Can't be fully ported as the change is from blob_remove(), which hasn't
been ported yet.
Problem: Items in a list given to :const can still be modified.
Solution: Work like ":lockvar! name" but don't lock referenced items.
Make locking a blob work.

Problem: filter() may give misleading error message.
Solution: Also mention Blob as an allowed argument.
fcb0b61d15
Rename Test_map_fails() to Test_map_filter_fails() from v8.2.0610 and
include the modeline.
Problem: Crash when reading a blob fails.
Solution: Avoid keeping a pointer to a freed blob object. (Dominique Pelle,
closesvim/vim#5890) Adjust error messages.
15352dc6ec
Problem: Blob test fails.
Solution: Check for different error when float feature is missing.
92be6e3f46
Nvim always has the float feature, but include the changes to the test
anyway.
Problem: Negative index doesn't work for Blob.
Solution: Make it work, add a test. (closesvim/vim#3856)
a5be9b6248
Leave tv_blob_get()'s return type untouched.
Problem: Incorrect error messages for functions that now take a Blob
argument.
Solution: Adjust the error messages. (Dominique Pelle, closesvim/vim#3846)
0d17f0d1c0
Problem: Not enough documentation for Blobs.
Solution: Add a section about Blobs.
d89682477c
Include doc changes for empty() from v7.4.1274.
Include some minor typo fixes.
Problem: Using freed memory, for loop over blob leaks memory.
Solution: Clear pointer after freeing memory. Decrement reference count
after for loop over blob.

Strings that previously decoded into a msgpack special for representing
BINs with NULs now convert to Blobs. It shouldn't be possible to decode
into this special anymore after this change?
Notably, Lua strings with NULs now convert to Blobs when passed to VimL.
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.
Problem: Code for Blob not sufficiently tested.
Solution: Add more tests. Fix uncovered crash. Add test_null_blob().
c0f5a78c15
eval0 and ex_echo's emsg-specific changes have already been ported.
These tests uncover another crash that was fixed in v8.1.0738.
Problem: Cannot handle binary data.
Solution: Add the Blob type. (Yasuhiro Matsumoto, closesvim/vim#3638)
6e5ea8d2a9
Nvim-specific Blob conversions are implemented in future commits.
Refactor write_blob() to use a FileDescriptor, as f_writefile() was
refactored to use one (does not apply to read_blob()).
Use var_check_lock() in f_add() for Blobs from v8.1.0897.
Add a modeline to test_blob.vim and fix some doc typos.
Include if_perl.txt's VIM::Blob() documentation. Interestingly, this
function already worked before this port, as it just returns a Blob
string literal, not an actual Blob object.
N/A patches for version.c:
vim-patch:8.1.0741: viminfo with Blob is not tested
Problem: Viminfo with Blob is not tested.
Solution: Extend the viminfo test. Fix reading a blob. Fixed storing a
special variable value.
8c8b8bb56c
vim-patch:8.1.1022: may use NULL pointer when out of memory
Problem: May use NULL pointer when out of memory. (Coverity)
Solution: Check for blob_alloc() returning NULL.

This generalizes diagnostic handling outside of just the scope of LSP.
LSP clients are now a specific case of a diagnostic producer, but the
diagnostic subsystem is decoupled from the LSP subsystem (or will be,
eventually).
