* jobstop/process_stop: send SIGTERM directlyDaniel Hahler2017-07-07
| | | | | This reverts the revert of #6644 (7c1a5d1d4), and handles it properly now (with tests).
* socket: Silence V641: buf size is not multiple of what it is cast toZyX2017-07-04

* socket.c: Disable Nagle's algorithm on TCP sockets (#6915)David Galeano2017-06-27
| | | | Reducing latency is more interesting than optimizing bandwidth for Nvim's typical use-cases.
* loop_close: Avoid infinite loop, and log it.Justin M. Keyes2017-06-07
| | | | | | Avoids a hang, and also helps diagnose issues like: https://github.com/neovim/neovim/pull/6594#issuecomment-298321826

* socket_watcher_start: Silence conversion warning for sin(6)_portJames McCoy2017-05-28
| | | | | | | Although in_port_t is a typedef for uint16_t, GCC in Ubuntu 12.04 complains about potential loss of data due to converting int to uint16_t. Since we know this isn't possible, silence the warning to avoid breaking QB until it gets upgraded to a newer Ubuntu.
* Server: Call uv_getaddrinfo with NULL service when no portJames McCoy2017-05-27
| | | | | | | | | | When using serverstart("ip.ad.d.r:") to listen on a random port, we need to abide by getaddrinfo()'s API and pass in a NULL service, rather than an empty string. When given an empty string, getaddrinfo() is free to search for a service by the given name (since the string isn't a number) which will fail. At least FreeBSD does perform this lookup.

* Server: use uv_getaddrinfo() for $NVIM_LISTEN_ADDRESSMarco Hinz2017-05-22
| | | | | | | | | | | | | | | | | | | This change implicitly adds IPv6 support. If the address contains ":", we try to use a TCP socket instead of a Unix domain socket. Everything in front of the last occurrence of ":" is the hostname and everything after it the port. If the hostname lookup fails, we fall back to using a Unix domain socket. If the port is empty ("localhost:"), a random port will be assigned. Examples: NVIM_LISTEN_ADDRESS=localhost:12345 -> TCP (IPv4 or IPv6), port: 12345 NVIM_LISTEN_ADDRESS=localhost: -> TCP (IPv4 or IPv6), port: random (> 1024) NVIM_LISTEN_ADDRESS=localhost:0 -> TCP (IPv4 or IPv6), port: random (> 1024) NVIM_LISTEN_ADDRESS=localhost -> Unix domain socket "localhost" in current dir

* Revert "event/process.c: send SIGTERM directly (#6644)"Justin M. Keyes2017-05-08
| | | | This reverts commit 34c3f03013375817d3d089e685793290eded553a.
* event/process.c: send SIGTERM directly (#6644)Daniel Hahler2017-05-04
| | | | | | | Send SIGTERM to processes directly, instead of waiting for ~1s. - removes TERM_TIMEOUT - changes KILL_TIMEOUT to milliseconds - removes Process.term_sent
* event: Remove "priority" concept.Justin M. Keyes2017-04-28
| | | | It was replaced by the "child queue" concept (MultiQueue).
* api/nvim_get_mode: Use child-queue instead of "priority".Justin M. Keyes2017-04-28
|
* input.c: Process only safe events before blocking.Justin M. Keyes2017-04-28
| | | | | Introduce multiqueue_process_priority() to process only events at or above a certain priority.
* api: nvim_get_mode()Justin M. Keyes2017-04-28
| | | | | | | | | | | | | | | | | | | | | | | | | | Asynchronous API functions are served immediately, which means pending input could change the state of Nvim shortly after an async API function result is returned. nvim_get_mode() is different: - If RPCs are known to be blocked, it responds immediately (without flushing the input/event queue) - else it is handled just-in-time before waiting for input, after pending input was processed. This makes the result more reliable (but not perfect). Internally this is handled as a special case, but _semantically_ nothing has changed: API users never know when input flushes, so this internal special-case doesn't violate that. As far as API users are concerned, nvim_get_mode() is just another asynchronous API function. In all cases nvim_get_mode() never blocks for more than the time it takes to flush the input/event queue (~µs). Note: This doesn't address #6166; nvim_get_mode() will provoke #6166 if e.g. `d` is operator-pending. Closes #6159

* win: libuv_process_spawn(): special-case cmd.exeRui Abreu Ferreira2017-04-12
| | | | | | | | | | | | | | | | | | Disable CommandLineToArgvW-standard quoting for cmd.exe. libuv assumes spawned processes follow the convention expected by CommandLineToArgvW(). But cmd.exe is non-conformant, so for cmd.exe: - With system([]), the caller has full control (and responsibility) to quote arguments correctly. - With system(''), shell* options are used. libuv quoting is disabled if argv[0] is: - cmd.exe - cmd - $COMSPEC resolving to a path with filename cmd.exe Closes #6329 References #6387

* Windows: libuv_process_spawn(): Allow libuv argument quoting/escaping.Rui Abreu Ferreira2017-01-10
| | | | | | | | | | | Closes #5360 References #3305 Reverts commit dc9652e68de163290abee880a74bf1727c715a1e. Disabling the quoting was does not solve the problem in general, and we would end up having to handle the quoting ourselves. See: https://github.com/JuliaLang/julia/issues/13776

* tui: "backpressure": Drop messages to avoid flooding.Justin M. Keyes2016-12-09
| | | | | | | | | Closes #1234 multiqueue: - Implement multiqueue_size() - Rename MultiQueueItem.parent to MultiQueueItem.parent_item, to avoid confusion with MultiQueue.parent.
* 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).

* tui.c: Do not wait for tui loop on teardown. (#4789)Justin M. Keyes2016-09-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because terminfo_stop() already ran, there is not much reason to wait for the loop to teardown.

* 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.
