|
|
21 | - mark event pipe fd as cloexec after a fork (analyzed by Sami Farin). |
|
|
22 | - (ecb) support m68k, m88k and sh (patch by Miod Vallat). |
|
|
23 | - use a reasonable fallback for EV_NSIG instead of erroring out |
|
|
24 | when we can't detect the signal set size. |
|
|
25 | - in the absence of autoconf, do not use the clock syscall |
|
|
26 | on glibc >= 2.17 (avoids the syscall AND -lrt on systems |
|
|
27 | doing clock_gettime in userspace). |
|
|
28 | - ensure extern "C" function pointers are used for externally-visible |
|
|
29 | loop callbacks (not watcher callbacks yet). |
|
|
30 | - (ecb) work around memory barriers and volatile apparently both being |
|
|
31 | broken in visual studio 2008 and later (analysed and patch by Nicolas Noble). |

|
|
34 | - destroying a non-default loop would stop the global waitpid |
|
|
35 | watcher (Denis Bilenko). |
|
|
36 | - queueing pending watchers of higher priority from a watcher now invokes |
|
|
37 | them in a timely fashion (reported by Denis Bilenko). |
|
|
38 | - add throw() to all libev functions that cannot throw exceptions, for |
|
|
39 | further code size decrease when compiling for C++. |
|
|
40 | - add throw () to callbacks that must not throw exceptions (allocator, |
|
|
41 | syserr, loop acquire/release, periodic reschedule cbs). |
|
|
42 | - fix event_base_loop return code, add event_get_callback, event_base_new, |
|
|
43 | event_base_get_method calls to improve libevent 1.x emulation and add |
|
|
44 | some libevent 2.x functionality (based on a patch by Jeff Davey). |
|
|
45 | - add more memory fences to fix a bug reported by Jeff Davey. Better |
|
|
46 | be overfenced than underprotected. |
|
|
47 | - ev_run now returns a boolean status (true meaning watchers are |
|
|
48 | still active). |
| 11 | - ev_once: undef EV_ERROR in ev_kqueue.c, to avoid clashing with |

| 12 | libev's EV_ERROR (reported by 191919). |

54 | - work around some kernels losing file descriptors by leaking |

55 | the kqueue descriptor in the child. |
|
|
56 | - work around linux inotify not reporting IN_ATTRIB changes for directories |
|
|
57 | in many cases. |
|
|
58 | - include sys/syscall.h instead of plain syscall.h. |
|
|
59 | - check for io watcher loops in ev_verify, check for the most |
|
|
60 | common reported usage bug in ev_io_start. |
|
|
61 | - choose socket vs. WSASocket at compiletime using EV_USE_WSASOCKET. |
|
|
62 | - always use WSASend/WSARecv directly on windows, hoping that this |
|
|
63 | works in all cases (unlike read/write/send/recv...). |
|
|
64 | - try to detect signals around a fork faster (test program by |
|
|
65 | Denis Bilenko). |
|
|
66 | - work around recent glibc versions that leak memory in realloc. |
|
|
67 | - rename ev::embed::set to ev::embed::set_embed to avoid clashing |
|
|
68 | the watcher base set (loop) method. |
|
|
69 | - rewrite the async/signal pipe logic to always keep a valid fd, which |
|
|
70 | simplifies (and hopefully correctifies :) the race checking |
|
|
71 | on fork, at the cost of one extra fd. |
|
|
72 | - add fat, msdos, jffs2, ramfs, ntfs and btrfs to the list of |
|
|
73 | inotify-supporting filesystems. |
|
|
74 | - move orig_CFLAGS assignment to after AC_INIT, as newer autoconf |
|
|
75 | versions ignore it before |
|
|
76 | (https://bugzilla.redhat.com/show_bug.cgi?id=908096). |
|
|
77 | - add some untested android support. |
|
|
78 | - enum expressions must be of type int (reported by Juan Pablo L). |
