* refactor: iwyu #31637Justin M. Keyes2024-12-23
| | | Result of `make iwyu` (after some "fixups").
* 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: Windows tilde expansion followup (#29380)Rafael Kitover2024-06-18
| | | | | | | | | | | | | | | | | | | | | | | Followup to #28515: Rename the static os_homedir() to os_uv_homedir() to emphasize that it is a wrapper around a libuv function. Add the function os_get_homedir() to os/env.c to return the cached homedir value as a const. Must be called after homedir is initialized or it fails. The difference between this function and the static os_uv_homedir() is that the latter gets the homedir from libuv and is used to initialize homedir in init_homedir(), while os_get_homedir() just returns homedir as a const if it's initialized and is public. Use the os_get_homedir() accessor for ~/ expansion on Windows to make the code more concise. Add a Windows section to main_spec.lua with tests for expanding ~/ and ~\ prefixes for files passed in on the command-line. Signed-off-by: Rafael Kitover <rkitover@gmail.com>

* fix(path): avoid chdir() when resolving path (#28799)zeertzjq2024-05-17
| | | | | | | | | | | | | | | | | | | | | | Use uv_fs_realpath() instead. It seems that uv_fs_realpath() has some problems on non-Linux platforms: - macOS and other BSDs: this function will fail with UV_ELOOP if more than 32 symlinks are found while resolving the given path. This limit is hardcoded and cannot be sidestepped. - Windows: while this function works in the common case, there are a number of corner cases where it doesn't: - Paths in ramdisk volumes created by tools which sidestep the Volume Manager (such as ImDisk) cannot be resolved. - Inconsistent casing when using drive letters. - Resolved path bypasses subst'd drives. Ref: https://docs.libuv.org/en/v1.x/fs.html#c.uv_fs_realpath I don't know if the old implementation that uses uv_chdir() and uv_cwd() also suffers from the same problems. - For the ELOOP case, chdir() seems to have the same limitations. - On Windows, Vim doesn't use anything like chdir() either. It uses _wfullpath(), while libuv uses GetFinalPathNameByHandleW().
* refactor(build): make all generated c files headersbfredl2024-04-27
| | | | | | | | | | | | | | | There's no "rule" or bad practice or whatever that says we cannot generate c files. it is is just that we have ~20 generated headers and ~2 generated sources and there is nothing in these two generated source files which sets them aparts. Lua bindings are not different from rpc bindings, and pathdef is not different from versiondef. So to simplify build logic and ease the future port to build.zig, streamline the build to only have generated headers, no direct generated .c files. Also "nlua_add_api_functions" had its prototype duplicated twice which defeated the point of having mandatory prototypes (one source of truth).
* refactor: add xmemcpyz() and use it in place of some xstrlcpy() (#28422)zeertzjq2024-04-20
| | | | | | Problem: Using xstrlcpy() when the exact length of the string to be copied is known is not ideal because it requires adding 1 to the length and an unnecessary strlen(). Solution: Add xmemcpyz() and use it in place of such xstrlcpy() calls.
* vim-patch:9.1.0161: expand() removes slash after env variable that ends with ↵zeertzjq2024-03-10

| | | | | | | | Problem: Various warnings from clang on MS-Windows. Solution: Avoid the warnings. (Yegappan Lakshmanan, closes vim/vim#10553) https://github.com/vim/vim/commit/a34b4460c2843c67a35a2d236b01e6cb9bc38734 Co-authored-by: Yegappan Lakshmanan <yegappan@yahoo.com>
* perf(os/env): os_getenv() allocation when there is no env var setbfredl2024-02-24
| | | | | | | | | | os_getenv("FOO") caches the result when $FOO is set to something non-empty. However, when $FOO was not set, every new call to os_getenv("FOO") would allocate a temporary scratch buffer to immediately throw away. This has an huge impact e.g. on logging which depends on potentially non-set env vars.
* 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.

* 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: 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.
* refactor: change some xstrndup() and xstrnsave() to xmemdupz() (#25959)zeertzjq2023-11-10
| | | | When the given length is exactly the number of bytes to copy, xmemdupz() makes the intention clearer.

* refactor: reorganize option header files (#25437)zeertzjq2023-09-30
| | | | | | - Move vimoption_T to option.h - option_defs.h is for option-related types - option_vars.h corresponds to Vim's option.h - option_defs.h and option_vars.h don't include each other
* refactor(map): enhanced implementation, Clean Code™, 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.

| | | | | | | | | | | | Problem: Vim9: no line break allowed inside a lambda. Solution: Handle line break inside a lambda in Vim9 script. https://github.com/vim/vim/commit/e40fbc2ca9fda07332a4da5af1fcaba91bed865b Omit skip_expr_concatenate(). Apply the change to skip_expr() instead. Omit eval_ga: Vim9 script only. Co-authored-by: Bram Moolenaar <Bram@vim.org>

| | | | | | MSVC has 4 different warning levels: 1 (severe), 2 (significant), 3 (production quality) and 4 (informational). Enabling level 3 warnings mostly revealed conversion problems, similar to GCC/clang -Wconversion flag.

* 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.
