* os_getenv, os_setenv: revert "widechar" implJustin M. Keyes2019-02-26
| | | | | | | | | | It's reported that the Windows widechar variants do automatically convert from the current codepage to UTF16, which is very helpful. So the "widechar" impls are a good direction. But libuv v1.12 does that for us, so the next commit will use that instead. ref #8398 ref #9267

* os_setenv: use _wputenv_s; remove vestigial code #7920Justin M. Keyes2019-02-25
| | | | | _putenv_s variant was left over from 810d31a43001, should have been removed in cd5b1315757e.
* I/O: ignore ENOTSUP for failed fsync()Justin M. Keyes2019-02-21
| | | | | | | | | Suggested by ZyX in https://github.com/neovim/neovim/issues/6725#issuecomment-312197691 : > There already is an exception if writing to a “device” (e.g. FIFO). > It makes sense to ignore certain errors like ENOTSUP or EOPNOTSUPP > since it is not something we or user can do anything about. ref #6725

* TUI: detect BSD vt consoleJustin M. Keyes2018-12-16
| | | | | | | | | | | | | | FreeBSD console sets TERM=xterm, but it does not support xterm features like cursor-shaping. GUI terminals typically set TERM=xterm-256color, so on FreeBSD we can guess that TERM=xterm is the degraded vt. OpenBSD console sets TERM=vt220 https://github.com/openbsd/src/blob/master/etc/etc.amd64/ttys NetBSD console sets TERM=vt100 https://github.com/NetBSD/src/blob/trunk/etc/etc.amd64/ttys closes #8644
* os/lang: use the correct LC_NUMERIC also for OS XBjörn Linse2018-12-13
|
* macOS: infer primary language if $LANG is empty #9345Marco Hinz2018-12-11
| | | | | | | | | | | | | | The macOS preferences have a section called `Language & Region`. There is always at least one language defined, the primary language. CFLocaleCopyPreferredLanguages() returns the languages defined in that section, the first element being the primary language. Use the primary language in case CFLocaleCopyCurrent() returns NULL. In the case that the above fallback does not work either, which is very unlikely, log the error and continue with an empty $LANG. References #9134

| | | | | | | | | | This is a regression after PR #7704: mac: Set $LANG based on the system locale CFStringGetCStringPtr sometimes returns "lang_region" = NULL, in this case CFStringGetCString is used instead, which places output to "buf", but "buf" was not used by the code.

* Check all child processes for exit in SIGCHLD handlerDavid Hotham2018-07-14
| | | | | | | | If a second and third child exit while we are already in the handler, we will only see a single additional SIGCHLD. Therefore the handler must not stop after processing a single child but should check all children. Fixes #8740
* Only waitpid() for processes that we care aboutDavid Hotham2018-07-13
| | | | | | | | | | | | | | | | | | | | | | It seems as though in an AppImage there's an extra child process that dies at some early point, before we have set up a SIGCHLD handler. So when we later get a SIGCHLD from a child that we do care about, waitpid(-1, ...) tells us about the extra child - and we don't notice that the interesting child has exited. Or something like that! See also: * https://patchwork.kernel.org/patch/9949491/ in which perf hit something similar * discussion at the AppImage repository: https://github.com/AppImage/AppImageKit/issues/812#issuecomment-404662110. Fix is to be explicit about which process we are waitpid()'ing for, so we never need be distracted by children that we don't know about. Fixes #8104

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes 2 failing tests in startup_spec.lua. The Windows-only `--literal` option complicates support of "stdin-as-text + file-args" (#7679). Could work around it, but it's not worth the trouble: - users have a reasonable (and englightening) alternative: nvim +"n *" - "always literal" is more consistent/predictable - avoids platform-specific special-case Unrelated changes: - Replace fileno(stdxx) with STDXX_FILENO for consistency (not motivated by any observed technical reason).

* | vim-patch:8.0.0355: using uninitialized memory when 'isfname' is empty (#8493)Jan Edmund Lazo2018-06-08

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

On today's systems these values are huge (4GB in my machine with 8GB of RAM since it's set as half the available memory by default) 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 swapping mechanism.
