17 | - mark event pipe fd as cloexec after a fork (analyzed by Sami Farin). |
|
|
18 | - (ecb) support m68k, m88k and sh (patch by Miod Vallat). |
|
|
19 | - use a reasonable fallback for EV_NSIG instead of erroring out |
|
|
20 | when we can't detect the signal set size. |
|
|
21 | - in the absence of autoconf, do not use the clock syscall |
|
|
22 | on glibc >= 2.17 (avoids the syscall AND -lrt on systems |
|
|
23 | doing clock_gettime in userspace). |
|
|
24 | - ensure extern "C" function pointers are used for externally-visible |
|
|
25 | loop callbacks (not watcher callbacks yet). |

28 | - destroying a non-default loop would stop the global waitpid |
|

|
|
30 | - queueing pending watchers of higher priority from a watcher now invokes |

|
|
50 | - work around linux inotify not reporting IN_ATTRIB changes for directories |
|
|
51 | in many cases. |
| 30 | - include sys/syscall.h instead of plain syscall.h. |
52 | - include sys/syscall.h instead of plain syscall.h. |
|
|
53 | - check for io watcher loops in ev_verify, check for the most |
|
|
54 | common reported usage bug in ev_io_start. |
|
|
55 | - choose socket vs. WSASocket at compiletime using EV_USE_WSASOCKET. |
|
|
56 | - always use WSASend/WSARecv directly on windows, hoping that this |
|
|
57 | works in all cases (unlike read/write/send/recv...). |
|
|
58 | - try to detect signals around a fork faster (test program by |
|
|
59 | Denis Bilenko). |
|
|
60 | - work around recent glibc versions that leak memory in realloc. |
|
|
61 | - rename ev::embed::set to ev::embed::set_embed to avoid clashing |
|
|
62 | the watcher base set (loop) method. |
|
|
63 | - rewrite the async/signal pipe logic to always keep a valid fd, which |
|
|
64 | simplifies (and hopefully correctifies :) the race checking |
|
|
65 | on fork, at the cost of one extra fd. |
|
|
66 | - add fat, msdos, jffs2, ramfs, ntfs and btrfs to the list of |
|
|
67 | inotify-supporting filesystems. |
|
|
68 | - move orig_CFLAGS assignment to after AC_INIT, as newer autoconf |
|
|
69 | versions ignore it before |
|
|
70 | (https://bugzilla.redhat.com/show_bug.cgi?id=908096). |
|
|
71 | - add some untested android support. |
|
|
72 | - enum expressions must be of type int (reported by Juan Pablo L). |
