* vim-patch:8.1.1413: error when the drive of the swap file was disconnected ↵zeertzjq2024-08-08
| | | | | | | | | | (#30009) Problem: Error when the drive of the swap file was disconnected. Solution: Try closing and re-opening the swap file. (closes vim/vim#4378) https://github.com/vim/vim/commit/b58a4b938c4bc7e0499700859bd7abba9acc5b11 Co-authored-by: Bram Moolenaar <Bram@vim.org>

* perf(extmarks): better track whether namespace has extmarks (#28615)zeertzjq2024-05-03
| | | | | | This avoids redraw when adding/removing an empty namespace for a window. This also avoids marktree traversal when clearing a namespace that has already been cleared, which is added as a benchmark.
* 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: 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: the long goodbyedundargoc2023-11-05
| | | | | | long is 32 bits on windows, while it is 64 bits on other architectures. This makes the type suboptimal for a codebase meant to be cross-platform. Replace it with more appropriate integer types.

| | | | Also remove some stray comments.
* refactor(memfile): change mf_trans and mf_hash from ad-hoc hashtable to Mapbfredl2023-09-10
| | | | | | | | | | Memfile used a private implementation of an open hash table with intrusive collision chains, but there is no reason to assume the standard khash_t based Map won't work just fine. Yes, we are taking full ownership and maintenance over memline and memfile. No one is going to maintain it for us. Trust the plan.
* refactor(memline): distinguish mutating uses of ml_get_buf()bfredl2023-08-24
| | | | | | | | | | | | | | ml_get_buf() takes a third parameters to indicate whether the caller wants to mutate the memline data in place. However the vast majority of the call sites is using this function just to specify a buffer but without any mutation. This makes it harder to grep for the places which actually perform mutation. Solution: Remove the bool param from ml_get_buf(). it now works like ml_get() except for a non-current buffer. Add a new ml_get_buf_mut() function for the mutating use-case, which can be grepped along with the other ml_replace() etc functions which can modify the memline.
* vim-patch:9.0.1583: get E304 when using 'cryptmethod' "xchacha20v2" (#23790)zeertzjq2023-05-28
| | | | | | | | | Problem: Get E304 when using 'cryptmethod' "xchacha20v2". (Steve Mynott) Solution: Add 4th crypt method to block zero ID check. Avoid syncing a swap file before reading the file.

| | | | | | | | | | | | Problem: Code is indented more than necessary. Solution: Use an early return where it makes sense. (Yegappan Lakshmanan, closes vim/vim#11813) https://github.com/vim/vim/commit/e8575988969579f9e1439181ae338b2ff74054a8 Partial port as this depends on some previous eval and 'smoothscroll' patches.

| | | | | | | | | | 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.

* vim-patch:8.1.0743: giving error messages is not flexibleJames McCoy2021-11-01

(Ozaki Kiichi, closes vim/vim#3302) Also make emsg() accept a "char *" argument.

* Merge #4486 'refactor: Remove maxmem, maxmemtot options'Justin M. Keyes2018-05-02
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After this change we never release blocks from memory (in practice it never happened because the memory limits are never reached). Let the OS take care of that. --- On today's systems the 'maxmem' and 'maxmemtot' values are huge (4+ GB) so the limits are never reached in practice, but Vim wastes a lot of time checking if the limit was reached. If the limit is reached Vim starts saving pieces of the swap file that were in memory to the disk. Said in a different way: Vim implements its own memory-paging mechanism. This is unnecessary and inefficient since the operating system already has virtual memory and will swap to the disk if programs start using too much memory. This change does... 1. Reduce the number of config options and need for documentation. 2. Make the code more efficient as we don't have to keep track of memory usage nor check if the memory limits were reached to start swapping to disk every time we need memory for buffers. 3. Simplify the code. Once memfile.c is simple enough it could be replaced by actual operating system memory mapping (mmap, MemoryViewOfFile...). This change does not prevent Vim to recover changes from swap files since the swapping code is never triggered with the huge limits set by default.

| | | | | | | | | | | | | | | | | | | | | | Problem: On MS-Windows large files (> 2Gbyte) cause problems. Solution: Use "off_T" instead of "off_t". Use "stat_T" instead of "struct stat".

(Ken Takata) https://github.com/vim/vim/commit/8767f52fbfd4f053ce00a978227c95f1d7d323fe Only the off_T changes are relevant, since all the "struct stat" usage is abstracted by libuv.
