    unix: handle POLLERR and POLLHUP in uv__stream_io

    bnoordhuis authored
    Fixes a busy loop when the file descriptor emits POLLHUP but not POLLIN
    or POLLOUT, e.g. when polling the read end of a pipe and the write end
    is closed.
    
    Fixes joyent/node#4923.

    windows: link with advapi32 and shell32 libraries

    piscisaureus authored
    Older versions of GYP would set up the Visual Studio project to link
    with these libraries by default, but this was changed in r1584 (see
    https://codereview.chromium.org/12256017).
    
    Closes #728

    linux: make uv_cpu_info() handle absent procfs

    bnoordhuis authored
    Return an error when reading from /proc files fails because the procfs
    isn't mounted.

    darwin: fix spurious uv_write2() segfault

    bnoordhuis authored
    We abuse uv_write2() to send over UDP handles to child processes.
    Don't call uv__stream_fd() on those handles, it's a macro that on OS X
    evaluates to a function that operates on a uv_stream_t with a couple of
    OS X specific fields. On other Unices it does (handle)->io_watcher.fd,
    which works but only by accident.
    
    Fixes joyent/node#4870.

    darwin: fix read from uninitialized struct kevent

    In the OS X fallback code, don't read from the struct when the kevent()
    syscall times out.

    test: remove 'is root?' check

    bnoordhuis authored
    I debug tests regularly as root (because dtrace and dtruss require the
    additional privileges). The 'is root?' check gets in the way more often
    than it prevents me from doing something silly. Remove it.

    linux, darwin: don't touch environ in uv_setup_args

    bnoordhuis authored
    Don't overwrite the environment. On OS X, the entries in the environ
    table are not necessarily adjacent. It's arguably also safer for setuid
    binaries.

    windows: initialize stop_flag explicitly

    saghul authored bnoordhuis committed
    The default loop lives in the bss section so it's zeroed on startup
    but loops created with uv_loop_new() live on the heap and contain
    random garbage. Initialize the stop_flag explicitly to avoid spurious
    bugs.

    unix: make uv_stop work when embedded

    bnoordhuis authored
    * Make uv_stop() work when libuv is embedded in another event loop.
    
    * Fix a small bug where loop->stop_flag was not reset when mode ==
      UV_RUN_ONCE or UV_RUN_NOWAIT. The next call to uv_run() would return
      immediately without doing any work.

    unix: set errno in sendfile emulation

    bnoordhuis authored
    The sendfile emulation in src/unix/fs.c polls the file descriptor for
    write readiness. If POLLERR or POLLHUP is set, it bails out but doesn't
    set errno (hence it doesn't report a useful error code). Rectify that.
    
    Fixes #620.

    linux: use eventfds for async handles

    bnoordhuis authored
    Use eventfds to drive async handles, fall back to regular pipes on older
    kernels (pre-2.6.22).
    
    Gives a nice boost on the async handle benchmarks. Before:
    
      12,516,113 async events in 5.0 seconds (2,503,222/s, 1,048,576 unique
      async1: 11.95 sec (83,701/sec)
      async2: 11.65 sec (85,862/sec)
      async4: 5.20 sec (192,154/sec)
      async8: 9.97 sec (100,315/sec)
      async_pummel_1: 1,000,000 callbacks in 2.56 seconds (389,919/sec)
      async_pummel_2: 1,000,000 callbacks in 2.65 seconds (377,205/sec)
      async_pummel_4: 1,000,000 callbacks in 2.18 seconds (457,704/sec)
      async_pummel_8: 1,000,000 callbacks in 4.19 seconds (238,632/sec)
    
    After:
    
      16,168,081 async events in 5.0 seconds (3,233,616/s, 1,048,576 unique
      async1: 11.08 sec (90,213/sec)
      async2: 10.17 sec (98,297/sec)
      async4: 4.81 sec (207,789/sec)
      async8: 8.98 sec (111,419/sec)
      async_pummel_1: 1,000,000 callbacks in 1.16 seconds (863,296/sec)
      async_pummel_2: 1,000,000 callbacks in 1.45 seconds (691,459/sec)
      async_pummel_4: 1,000,000 callbacks in 0.66 seconds (1,514,770/sec)
      async_pummel_8: 1,000,000 callbacks in 1.42 seconds (704,549/sec)
    
    That's a speedup from anywhere between 10% to 330%.

    darwin: implement uv_set_process_title, part 2

    bnoordhuis authored
    Make changes to the process title visible to tools like `ps`.
    
    The argv clobber technique is reasonably portable across Unices;
    the common code has been moved into src/unix/proctitle.c and is used
    on Linux and OS X. Other platforms will probably follow in the future.

    unix: short-circuit on no-op io watcher changes

    bnoordhuis authored
    Don't add the io watcher to the watcher queue if the requested change
    is effectively a no-op, that is, when the event mask doesn't change.
    
    The exception here is sunos because the event ports backend requires
    that watched file descriptors are re-added on every turn of the event
    loop.
    
    This commit is a micro-optimization, it does not change the event
    loop's observable behavior in any way.

    unix: handle EINPROGRESS for unix sockets

    bnoordhuis authored
    Before this commit, it was assumed that connect() on UNIX sockets never
    returns EINPROGRESS. It turned out to be a bad assumption: Dave Pacheco
    reports sporadic hangups on SmartOS because of that.
    
    It's not clear to me _why_ the Illumos kernel returns that error but
    that's inconsequential: whatever the cause, libuv needs to handle it
    and now it does.
    
    Fixes joyent/node#4785.
