|
|
12 | - for simple request api, initialise result/errorno to -1/ECANCELED. |
|
|
13 | - fix a deadlock where a wakeup signal could be missed when |
|
|
14 | a timeout occured at the same time. |
|
|
15 | - use nonstandard but maybe-working-on-bsd fork technique. |
|
|
16 | - use fewer time() syscalls when waiting for new requests. |
|
|
17 | - fix a path-memory-leak in readdir when using the wrappers |
|
|
18 | (reported by Thomas L. Shinnick). |
|
|
19 | - support a max_idle value of 0. |
|
|
20 | - support setting of idle timeout value (eio_set_idle_timeout). |
| 7 | - readdir: correctly handle malloc failures. |

44 | - "fix" demo.c so that it works as non-root. |
|
|
45 | - suppoert utimes seperately from futimes, as some systems have |
|
|
46 | utimes but not futimes. |
|
|
47 | - use _POSIX_MEMLOCK_RANGE for mlock. |
|
|
48 | - do not (errornously) overwrite CFLAGS in configure.ac. |
|
|
49 | - mknod used int3 for dev_t (ยง2 bit), not offs (64 bit). |
|
|
50 | - fix memory corruption in eio_readdirx for the flags |
|
|
51 | combination EIO_READDIR_STAT_ORDER | EIO_READDIR_DIRS_FIRST. |
|
|
52 | - port to openbsd (another blatantly broken non-UNIX/POSIX platform). |
|
|
53 | - fix eio_custom prototype. |
|
|
54 | - work around a Linux (and likely FreeBSD and other kernels) bug |
|
|
55 | where sendfile would not transfer all the requested bytes on |
|
|
56 | large transfers, using a heuristic. |
|
|
57 | - use libecb, and apply lots of minor space optimisations. |
|
|
58 | - disable sendfile on darwin, broken as everything else. |
|
|
59 | - add realpath request and implementation. |
|
|
60 | - cancelled requests will still invoke their request callbacks. |
|
|
61 | - add fallocate. |
|
|
62 | - do not acquire any locks when forking. |
|
|
63 | - incorporated some mingw32 changes by traviscline. |
|

66 | - remove useless use of volatile variables. |
|
|
67 | - fix memory leak when reaping threads. |
|
|
68 | - use utime now uses nanosecond resolution on posix 2008 systems. |
|
|
69 | - allow taking advantage of posix 2008 xxxat functions and fdopendir |
|
|
70 | by implementing a working directory abstraction. |
|

|
|
74 | - wtf. etp_proc returned 0, and no compiler ever complained. |

|
|
76 | (cygwin) provides them for a while now. |
|
|
77 | - provide pread/pwrite implementations for win32. |
|
|
78 | - implement aio_realpath for windows. |
