* refactor(api)!: rename Dictionary => DictJustin M. Keyes2024-09-23
| | | | | | | | | | | | | | In the api_info() output: :new|put =map(filter(api_info().functions, '!has_key(v:val,''deprecated_since'')'), 'v:val') ... {'return_type': 'ArrayOf(Integer, 2)', 'name': 'nvim_win_get_position', 'method': v:true, 'parameters': [['Window', 'window']], 'since': 1} The `ArrayOf(Integer, 2)` return type didn't break clients when we added it, which is evidence that clients don't use the `return_type` field, thus renaming Dictionary => Dict in api_info() is not (in practice) a breaking change.
* refactor(typval)!: remove distinction of binary and nonbinary stringsbfredl2024-06-27
| | | | | | | | | | | | | | | | | | | | | This is a breaking change which will make refactor of typval and shada code a lot easier. In particular, code that would use or check for v:msgpack_types.binary in the wild would be broken. This appears to be rarely used in existing plugins. Also some cases where v:msgpack_type.string would be used to represent a binary string of "string" type, we use a BLOB instead, which is vimscripts native type for binary blobs, and already was used for BIN formats when necessary. msgpackdump(msgpackparse(data)) no longer preserves the distinction of BIN and STR strings. This is very common behavior for language-specific msgpack bindings. Nvim uses msgpack as a tool to serialize its data. Nvim is not a tool to bit-perfectly manipulate arbitrary msgpack data out in the wild. The changed tests should indicate how behavior changes in various edge cases.
* refactor(typval): don't use msgpack_packer for msgpackdump()bfredl2024-06-24

* build: adjust clang-tidy warning exclusion logicdundargoc2023-11-20
| | | | | | | Enable all clang-tidy warnings by default instead of disabling them. This ensures that we don't miss useful warnings on each clang-tidy version upgrade. A drawback of this is that it will force us to either fix or adjust the warnings as soon as possible.
* build: remove PVSdundargoc2023-11-12
| | | | | | | We already have an extensive suite of static analysis tools we use, which causes a fair bit of redundancy as we get duplicate warnings. PVS is also prone to give false warnings which creates a lot of work to identify and disable.

* build: remove clint error suppression #21782dundargoc2023-01-13
| | | | | | | | | | | | | | | Fix remaining clint errors and remove error suppression completely. Rename the lint targets to align with the established naming convention: - lintc-clint lints with clint.py. - lintc-uncrustify lints with uncrustify. - lintc runs both targets. lintc is also provided as a make target for convenience. After this change we can remove these files: https://github.com/neovim/doc/tree/gh-pages/reports/clint https://github.com/neovim/doc/blob/main/ci/clint-errors.sh
* refactor: move klib out of src/nvim/ #20341dundargoc2022-09-25
| | | | It's confusing to mix vendored dependencies with neovim source code. A clean separation is simpler to keep track of and simpler to document.

* vim-patch:8.1.0735: cannot handle binary dataSean Dewar2021-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Cannot handle binary data. Solution: Add the Blob type. (Yasuhiro Matsumoto, closes vim/vim#3638) https://github.com/vim/vim/commit/6e5ea8d2a995b32bbc5972edc4f827b959f2702f 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. https://github.com/vim/vim/commit/8c8b8bb56c724cc1bfc3d8520eec33f2d399697c vim-patch:8.1.1022: may use NULL pointer when out of memory Problem: May use NULL pointer when out of memory.

* vim-patch:8.2.0111: VAR_SPECIAL is also used for booleansBilly Su2020-06-06
| | | | | | Problem: VAR_SPECIAL is also used for booleans. Solution: Add VAR_BOOL for better type checking. https://github.com/vim/vim/commit/9b4a15d5dba354d2e1e02871470bad103f34769a
* vim-patch:8.1.1007: using closure may consume a lot of memoryerw72020-05-07

* eval: Fix failing testZyX2017-01-07
|
* eval: Make sure that copyID is reset when neededZyX2017-01-07
| | | | | Works by making value pushed on stack represent the exhausted list. Fixes #5901, except for dictionaries which need similar adjustment.
* eval/typval_encode: Dump empty dictionary before checking for refcycleZyX2017-01-06
| | | Otherwise copyID will stay forever on empty dictionaries.
* eval/typval_encode: Use TYPVAL_ENCODE_CONV_EMPTY_DICT for partialsZyX2017-01-06
|
* eval: Fix errorneous early exit when converting lists and dictionariesZyX2017-01-03
|
* eval/typval_encode: Handle NULL partials properlyZyX2017-01-03
|
* eval/typval_encode: Provide proper values as dict argumentZyX2017-01-03
|
* eval/typval_encode: Refactor arguments to argument macrosesZyX2017-01-03
| | | Fixed local test failures somewhere in process.
* eval/typval_encode: Rename some \*tv variablesZyX2017-01-03
| | | | | Renames `tv` function argument to `top_tv` and `cur_tv` variable to `tv`, so `tv` will mean something more or less the same in both _TYPVAL_ENCODE_CONVERT_ONE_VALUE and _TYPVAL_ENCODE_ENCODE functions.
* eval/typval_encode: Fix infinite loopZyX2017-01-03
| | | | | | | | | Occurs when trying to dump a partial with attached self dictionary which references that partial. “Infinite” loop should normally result in Neovim killed by OOM killer. Also moved the place when partials are unreferenced by clear_tv: from …FUNC_START to …FUNC_END.
* eval/typval_encode: Fix linter errorsZyX2017-01-03
|
* eval/typval_encode: Fix crashesZyX2017-01-03
|
* eval/typval_encode: Refactor big-big macros into .c.h fileZyX2017-01-03
This makes gdb backtraces much more meaningful: specifically I now know at which line it crashes in place of seeing that it crashes at TYPVAL_ENCODE_DEFINE_CONV_FUNCTIONS macros invocation.
