* refactor: Remove strncpy/STRNCPY. (#6008)Justin M. Keyes2017-01-26
| | | | | | | | | | | | | | | Closes #731 References #851 Note: This does not remove some intentional legacy usages of strncpy. - memcpy isn't equivalent because it doesn't check the string length of `src`, and doesn't zero-out the remainder of `dst`. - xstrlcpy isn't equivalent because it doesn't zero-out the remainder of `dst`. Some Vim logic depends on that (e.g. ex_append which calls vim_strnsave).

* Windows: vim_getenv(): Find runtime relative to nvim. #3303 (#5929)Justin M. Keyes2017-01-11
| | | | | | | | | | | | In Windows we cannot rely on absolute install paths to point to the location of the runtime. Vim uses the path of the current binary as a possible location for the runtime folder. In Neovim the install location places the runtime folder in ../share/nvim/runtime. In Vim this logic is guarded by USE_EXE_NAME, which is defined for win32 and macOS. TODO: We may need to incorporate similar logic for macOS: https://github.com/vim/vim/blob/0cdb72aa38c4a0140c94d56bf8bc17cb30260ebf/src/misc1.c#L4287-L4308
* XDG: Windows: resolve $LOCALAPPDATA, $TEMP (#5278)Rui Abreu Ferreira2017-01-08
| | | | | | | | | | After #4964 environment variables in the XDG "fallback" table are no longer expanded. Fallback to correctly expanded $LOCALAPPDATA, $TEMP. If that fails (unlikely), fallback to hard-coded paths (e.g. ~/AppData/Local). Closes #5255

* out_data_decide_throttle(): timeout instead of hard limit.Justin M. Keyes2016-12-10
| | | | | | | Instead of managing max_visits, check the time every N visits. This avoids edge cases where max_visits is large but the chunk frequency slowed down, which would causing the "..." pulse to show for a very long time. It's more important to show output at reasonable intervals than to avoid calling os_hrtime().
* out_data_decide_throttle(): Avoid too-small final chunk.Justin M. Keyes2016-12-10
|
* os/shell: do_os_system(): Always show last chunk.Justin M. Keyes2016-12-10
| | | | | | | | | | | | | | | | | | | | | This ameliorates use-cases like: :!cat foo.txt :make where the user is interested in the last few lines of output. Try these shell-based ex-commands before/after this commit: :grep -r '' * :make :!yes :!grep -r '' * :!git grep '' :!cat foo :!echo foo :!while true; do date; done :!for i in `seq 1 20000`; do echo XXXXXXXXXX $i; done In all cases the last few lines of the command should always be shown, regardless of where throttling was triggered.
* os/shell: Throttle :! output, pulse "..." message.Justin M. Keyes2016-12-09
| | | | | | | | | | | | | | | | | | | | | | | | | | Periodically skip :! spam. This is a "cheat" that works for all UIs and greatly improves responsiveness when :! spams MB or GB of output: :!yes :!while true; do date; done :!git grep '' :grep -r '' * After ~10KB of data is seen from a single :! invocation, output will be skipped for ~1s and three dots "..." will pulse in the bottom-left. Thereafter the behavior alternates at every: * 10KB received * ~1s throttled This also avoids out-of-memory which could happen with large :! outputs. Note: This commit does not change the behavior of execute(':!foo'). execute(':!foo') returns the string ':!foo^M', it captures *only* Vim messages, *not* shell command output. Vim behaves the same way. Use system('foo') for capturing shell command output. Closes #1234 Helped-by: oni-link <knil.ino@gmail.com>

* system('foo &', 'bar'): Show error, don't crash.Justin M. Keyes2016-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Closes #3529 Closes #5241 In Vim, :echo system('cat - &', 'foo') works because for both system() and :! Vim writes input to a temp file and uses shell syntax to redirect the file to the backgrounded `cat` (get_cmd_output() .. make_filter_cmd()). In Nvim, :echo system('cat - &', 'foo') fails because we write the input directly via pipes (shell.c:do_os_system()), but (per POSIX[1]) backgrounded process input stream is redirected from /dev/null (unless overridden by shell redirection; supported only by some shells [2]), so our writes are ignored, the process exits quickly, and if we are writing data larger than the buffer size we'll see EPIPE. This still works: :%w !tee > foo1358.txt & but this does not: :%w !tee foo1358.txt & though it *should* (why doesn't it?) because we still do the temp file dance in do_bang() .. do_filter().

* event/multiqueue.c: Rename "queue" to "multiqueue".Justin M. Keyes2016-10-02
| | | | | | | | | | | | | | `lib/queue.h` implements a basic queue. `event/queue.c` implements a specialized data structure on top of lib/queue.h; it is not a "normal" queue. Rename the specialized multi-level queue implemented in event/queue.c to "multiqueue", to avoid confusion when reading the code. Before this change one can eventually notice that "macros (uppercase symbols) are for the normal queue, lowercase operations are for the multi-level queue", but that is unnecessary friction for new developers (or existing developers just visiting this part of the codebase).

* signal_init: Always unblock SIGCHLD. (#5243)Justin M. Keyes2016-08-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Inherited signal mask may block SIGCHLD, which causes libuv to hang at epoll_wait. Closes #5230 Helped-by: Nicolas Hillegeer <nicolas@hillegeer.com> Helped-by: John Szakmeister <john@szakmeister.net> Note: the #pragma gymnastics are a workaround for broken system headers on macOS. signal.h: int sigaddset(sigset_t *, int); #define sigaddset(set, signo) (*(set) |= __sigbits(signo), 0) sys/_types/_sigset.h: typedef __darwin_sigset_t sigset_t; sys/_types.h: typedef __uint32_t __darwin_sigset_t; /* [???] signal set */ sigset_t is defined as unsigned int, but the sigaddset() ORs it with an int, mixing the types. So GCC generates a sign-conversion warning: sig.c:9:13: warning: implicit conversion changes signedness: 'int' to 'unsigned int' [-Wsign-conversion] (*(&s) |= __sigbits((sigset_t) 20), 0); ~~ ^~~~~~~~~~~~~~~~~~~~~~~~ 1 warning generated. System headers are normally ignored when the compiler generates warnings: https://gcc.gnu.org/onlinedocs/cpp/System-Headers.html > GCC gives code found in system headers special treatment. All warnings, > other than those generated by ‘#warning’ (see Diagnostics), are suppressed > while GCC is processing a system header. Macros defined in a system header > are immune to a few warnings wherever they are expanded. This immunity is > granted on an ad-hoc basis, when we find that a warning generates lots of > false positives because of code in macros defined in system headers. Instead of the #pragma workaround, we could cast the sigset_t pointer: # if defined(__APPLE__) sigaddset((int *)&mask, SIGCHLD); # else sigaddset(&mask, SIGCHLD); # endif but that could break if the headers are later fixed.

| | | | | | | | | | | | | | | | | | | | | | | | The whole stream buffer is now put on screen at once instead of only data up to the last newline. This has some advantages: * RBuffer cannot wrap around, so we never forget to output second half of the buffer. * Stream data is not delayed anymore, because we don't have to wait for a newline. This works by remembering the last used screen column.
