* fix(log): RPC log format #32337Justin M. Keyes2025-02-05
| | | | | | | | | | | | | Problem: RPC log messages show `log_notify` function name, which is not useful: DBG 2025-02-04T22:28:02.419 ui.37862 log_notify:57: RPC -> 3: [notify] nvim_ui_set_focus DBG 2025-02-04T22:28:02.419 nvim.37863.0 log_notify:57: RPC <- 1: [notify] nvim_ui_set_focus Solution: Call logmsg() directly. DBG 2025-02-04T22:42:00.104 ui.40680 RPC: -> 3: [notify] nvim_ui_attach DBG 2025-02-04T22:42:00.104 ui.40680 RPC: -> 3: [notify] nvim_set_client_info
* refactor: iwyu #31637Justin M. Keyes2024-12-23
| | | Result of `make iwyu` (after some "fixups").
* 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: rename "process" => "proc" #30387Justin M. Keyes2024-09-15
| | | | | | | | | | | | Problem: - "process" is often used as a verb (`multiqueue_process_events`), which is ambiguous for cases where it's used as a topic. - The documented naming convention for processes is "proc". - `:help dev-name-common` - Shorter is better, when it doesn't harm readability or discoverability. Solution: Rename "process" => "proc" in all C symbols and module names.
* refactor(shada): rework msgpack decoding without msgpack-cbfredl2024-08-05
| | | | | | | 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.
* refactor(shada): use msgpack_sbuffer lessbfredl2024-06-11
| | | | | | | Work towards getting rid of libmsgpack depedency eventually. msgpack_sbuffer is just a string buffer, we can use our own String type.
* refactor(io): make rstream use a linear bufferbfredl2024-06-08
| | | | | | | | | If you like it you shouldn't put a ring on it. This is what _every_ consumer of RStream used anyway, either by calling rbuffer_reset, or rbuffer_consumed_compact (same as rbuffer_reset without needing a scratch buffer), or by consuming everything in each stream_read_cb call directly.
* refactor(io): separate types for read and write streamsbfredl2024-05-31
| | | | | | | | | | | | This is a structural refactor with no logical changes, yet. Done in preparation for simplifying rstream/rbuffer which will require more state inline in RStream. The initial idea was to have RStream and WStream as sub-types symetrically but that doesn't work, as sockets are both reading and writing. Also there is very little write-specific state to start with, so the benefit of a separate WStream struct is a lot smaller. Just document what fields in `Stream` are write specific.
* feat(api): broadcast events to ALL channels #28487Justin M. Keyes2024-05-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: `vim.rpcnotify(0)` and `rpcnotify(0)` are documented as follows: If {channel} is 0, the event is broadcast to all channels. But that's not actually true. Channels must call `nvim_subscribe` to receive "broadcast" events, so it's actually "multicast". - Assuming there is a use-case for "broadcast", the current model adds an extra step for broadcasting: all channels need to "subscribe". - The presence of `nvim_subscribe` is a source of confusion for users, because its name implies something more generally useful than what it does. Presumably the use-case of `nvim_subscribe` is to avoid "noise" on RPC channels not expected a broadcast notification, and potentially an error if the channel client reports an unknown event. Solution: - Deprecate `nvim_subscribe`/`nvim_unsubscribe`. - If applications want to multicast, they can keep their own multicast list. Or they can use `nvim_list_chans()` and `nvim_get_chan_info()` to enumerate and filter the clients they want to target. - Always send "broadcast" events to ALL channels. Don't require channels to "subscribe" to receive broadcasts. This matches the documented behavior of `rpcnotify()`.

* test: silence expected errorsdundargoc2024-04-02
| | | | This will remove unrelated errors in .nvimlog at the end of test output.
* refactor(msgpack): allow flushing buffer while packing msgpackbfredl2024-03-07
| | | | | | | | | | | | | | Before, we needed to always pack an entire msgpack_rpc Object to a continous memory buffer before sending it out to a channel. But this is generally wasteful. it is better to just flush whatever is in the buffer and then continue packing to a new buffer. This is also done for the UI event packer where there are some extra logic to "finish" of an existing batch of nevents/ncalls. This doesn't really stop us from flushing the buffer, just that we need to update the state machine accordingly so the next call to prepare_call() always will start with a new event (even though the buffer might contain overflow data from a large event).
* refactor(api): make freeing of return-value opt-in instead of opt outbfredl2024-02-21
| | | | | | | | | As only a few API functions make use of explicit freeing of the return value, make it opt-in instead. The arena is always present under the hood, so `Arena *arena` arg now doesn't mean anything other than getting access to this arena. Also it is in principle possible to return an allocated value while still using the arena as scratch space for other stuff (unlikely, but there no reason to not allow it).
* refactor(api): use arena for channel info and terminal infobfredl2024-02-18

* refactor(eval): use arena when converting typvals to Objectbfredl2024-02-15
| | | | | | | | | | | | Note: this contains two _temporary_ changes which can be reverted once the Arena vs no-Arena distinction in API wrappers has been removed. Both nlua_push_Object and object_to_vim_take_luaref() has been changed to take the object argument as a pointer. This is not going to be necessary once these are only used with arena (or not at all) allocated Objects. The object_to_vim() variant which leaves luaref untouched might need to stay for a little longer.
* refactor(lua): use Arena when converting from lua stack to API argsbfredl2024-02-13
| | | | | | | | | | | | and for return value of nlua_exec/nlua_call_ref, as this uses the same family of functions. NB: the handling of luaref:s is a bit of a mess. add api_luarefs_free_XX functions as a stop-gap as refactoring luarefs is a can of worms for another PR:s. as a minor feature/bug-fix, nvim_buf_call and nvim_win_call now preserves arbitrary return values.
* refactor(api): make cstr_as_string accept "const char*"bfredl2024-02-09
| | | | | In the context a String inside an Object/Dictionary etc is consumed, it is considered to be read-only.
* fix(rpc): assertion failure due to invalid msgpack inputnwounkn2024-01-21
| | | | | | | | | Problem: rbuffer_consumed assertion fails if Unpacker fails to parse msgpack, because it doesn't consume bytes on errors Solution: Call rbuffer_consumed_compact only if Unpacker isn't closed
* refactor(IWYU): fix headersdundargoc2024-01-11
| | | | | | Remove `export` pramgas from defs headers as it causes IWYU to believe that the definitions from the defs headers comes from main header, which is not what we really want.

* refactor: change event_create() to a macro (#26343)zeertzjq2023-12-01
| | | A varargs functions can never be inlined, so a macro is faster.
* build: don't define FUNC_ATTR_* as empty in headers (#26317)zeertzjq2023-11-30
| | | | | | FUNC_ATTR_* should only be used in .c files with generated headers. Defining FUNC_ATTR_* as empty in headers causes misuses of them to be silently ignored. Instead don't define them by default, and only define them as empty after a .c file has included its generated header.

* build: rework IWYU mapping filesdundargoc2023-11-25
| | | | | Create mapping to most of the C spec and some POSIX specific functions. This is more robust than relying files shipped with IWYU.
* refactor: enable formatting for ternariesdundargoc2023-11-20
| | | | | | This requires removing the "Inner expression should be aligned" rule from clint as it prevents essentially any formatting regarding ternary operators.
* 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.

* refactor(map): enhanced implementation, Clean Codeā„¢, etc etcbfredl2023-09-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This involves two redesigns of the map.c implementations: 1. Change of macro style and code organization The old khash.h and map.c implementation used huge #define blocks with a lot of backslash line continuations. This instead uses the "implementation file" .c.h pattern. Such a file is meant to be included multiple times, with different macros set prior to inclusion as parameters. we already use this pattern e.g. for eval/typval_encode.c.h to implement different typval encoders reusing a similar structure. We can structure this code into two parts. one that only depends on key type and is enough to implement sets, and one which depends on both key and value to implement maps (as a wrapper around sets, with an added value[] array) 2. Separate the main hash buckets from the key / value arrays Change the hack buckets to only contain an index into separate key / value arrays This is a common pattern in modern, state of the art hashmap implementations. Even though this leads to one more allocated array, it is this often is a net reduction of memory consumption. Consider key+value consuming at least 12 bytes per pair. On average, we will have twice as many buckets per item. Thus old implementation: 2*12 = 24 bytes per item New implementation 1*12 + 2*4 = 20 bytes per item And the difference gets bigger with larger items. One might think we have pulled a fast one here, as wouldn't the average size of the new key/value arrays be 1.5 slots per items due to amortized grows? But remember, these arrays are fully dense, and thus the accessed memory, measured in _cache lines_, the unit which actually matters, will be the fully used memory but just rounded up to the nearest cache line boundary. This has some other interesting properties, such as an insert-only set/map will be fully ordered by insert only. Preserving this ordering in face of deletions is more tricky tho. As we currently don't use ordered maps, the "delete" operation maintains compactness of the item arrays in the simplest way by breaking the ordering. It would be possible to implement an order-preserving delete although at some cost, like allowing the items array to become non-dense until the next rehash. Finally, in face of these two major changes, all code used in khash.h has been integrated into map.c and friends. Given the heavy edits it makes no sense to "layer" the code into a vendored and a wrapper part. Rather, the layered cake follows the specialization depth: code shared for all maps, code specialized to a key type (and its equivalence relation), and finally code specialized to value+key type.
* feat(msgpack_rpc): support out-of-order responses on `msgpack-rpc`Alisue2023-08-26
| | | | | | | | | | | | | Added to support MessagePack-RPC fully compliant clients that do not return responses in request order. Although it is currently not an efficient implementation for full compliance and full compliance cannot be guaranteed, the addition of the new client type `msgpack-rpc` creates a situation where "if the client type is `msgpack-rpc`, then backward compatibility is ignored and full compliance with MessagePack- RPC compliance is justified even if backward compatibility is ignored if the client type is `msgpack-rpc`.

* refactor(api): new helper macrosFamiu Haque2023-05-23
| | | | Adds new API helper macros `CSTR_AS_OBJ()`, `STATIC_CSTR_AS_OBJ()`, and `STATIC_CSTR_TO_OBJ()`, which cleans up a lot of the current code. These macros will also be used extensively in the upcoming option refactor PRs because then API Objects will be used to get/set options. This PR also modifies pre-existing code to use old API helper macros like `CSTR_TO_OBJ()` to make them cleaner.
* refactor(map): avoid duplicated khash_t types for valuesbfredl2023-05-17
| | | | | | | | | | | | | | | | | | | | | This reduces the total number of khash_t instantiations from 22 to 8. Make the khash internal functions take the size of values as a runtime parameter. This is abstracted with typesafe Map containers which are still specialized for both key, value type. Introduce `Set(key)` type for when there is no value. Refactor shada.c to use Map/Set instead of khash directly. This requires `map_ref` operation to be more flexible. Return pointers to both key and value, plus an indicator for new_item. As a bonus, `map_key` is now redundant. Instead of Map(cstr_t, FileMarks), use a pointer map as the FileMarks struct is humongous. Make `event_strings` actually work like an intern pool instead of wtf it was doing before.

* build: allow IWYU to fix includes for all .c filesdundargoc2022-11-15
| | | | | | | | | | Allow Include What You Use to remove unnecessary includes and only include what is necessary. This helps with reducing compilation times and makes it easier to visualise which dependencies are actually required. Work on https://github.com/neovim/neovim/issues/549, but doesn't close it since this only works fully for .c files and not headers.
* 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.
* refactor(api): provide a temporary copy solution for nvim_call_atomicbfredl2022-08-24
