|
11 | - fix a deadlock where a wakeup signal could be missed when |
|
|
12 | a timeout occured at the same time. |
|
|
13 | - use nonstandard but maybe-working-on-bsd fork technique. |
|
|
14 | - use fewer time() syscalls when waiting for new requests. |
|
|
15 | - fix a path-memory-leak in readdir when using the wrappers |
|
|
16 | (reported by Thomas L. Shinnick). |
|
|
17 | - support a max_idle value of 0. |
|
|
18 | - support setting of idle timeout value (eio_set_idle_timeout). |
| 7 | - readdir: correctly handle malloc failures. |
19 | - readdir: correctly handle malloc failures. |
| 8 | - readdir: new flags argument, can return inode |
20 | - readdir: new flags argument, can return inode |
| 9 | and possibly filetype, can sort in various ways. |
21 | and possibly filetype, can sort in various ways. |
| 10 | - readdir: stop immediately when cancelled, do |
22 | - readdir: stop immediately when cancelled, do |
| 11 | not continue reading the directory. |
23 | not continue reading the directory. |

| 23 | - also use sendfile emulation for ENOTSUP and EOPNOTSUPP |
35 | - also use sendfile emulation for ENOTSUP and EOPNOTSUPP |
| 24 | error codes. |
36 | error codes. |
| 25 | - add OS-independent EIO_MT_* and EIO_MS_* flag enums. |
37 | - add OS-independent EIO_MT_* and EIO_MS_* flag enums. |
| 26 | - add eio_statvfs/eio_fstatvfs. |
38 | - add eio_statvfs/eio_fstatvfs. |
| 27 | - add eio_mlock/eio_mlockall and OS-independent MCL_* flag enums. |
39 | - add eio_mlock/eio_mlockall and OS-independent MCL_* flag enums. |
|
|
40 | - no longer set errno to 0 before making syscalls, this only lures |
|
|
41 | people into the trap of believing errno shows success or failure. |
|
|
42 | - "fix" demo.c so that it works as non-root. |
|
|
43 | - suppoert utimes seperately from futimes, as some systems have |
|
|
44 | utimes but not futimes. |
|
|
45 | - use _POSIX_MEMLOCK_RANGE for mlock. |
|
|
46 | - do not (errornously) overwrite CFLAGS in configure.ac. |
|
|
47 | - mknod used int3 for dev_t (ยง2 bit), not offs (64 bit). |
|
|
48 | - fix memory corruption in eio_readdirx for the flags |
|
|
49 | combination EIO_READDIR_STAT_ORDER | EIO_READDIR_DIRS_FIRST. |
|
|
50 | - port to openbsd (another blatantly broken non-UNIX/POSIX platform). |
|
|
51 | - fix eio_custom prototype. |
|
|
52 | - work around a Linux (and likely FreeBSD and other kernels) bug |
|
|
53 | where sendfile would not transfer all the requested bytes on |
|
|
54 | large transfers, using a heuristic. |
|
|
55 | - use libecb, and apply lots of minor space optimisations. |
|
|
56 | - disable sendfile on darwin, broken as everything else. |
|
|
57 | - add realpath request and implementation. |
|
|
58 | - cancelled requests will still invoke their request callbacks. |
|
|
59 | - add fallocate. |
|
|
60 | - do not acquire any locks when forking. |
|
|
61 | - incorporated some mingw32 changes by traviscline. |
|
|
62 | - added syncfs support, using direct syscall. |
|
|
63 | - set thread name on linux (ps -L/Hcx, top, gdb). |
|
|
64 | - remove useless use of volatile variables. |
|
|
65 | - fix memory leak when reaping threads. |
|
|
66 | - use utime now uses nanosecond resolution on posix 2008 systems. |
|
|
67 | - allow taking advantage of posix 2008 xxxat functions and fdopendir |
|
|
68 | by implementing a working directory abstraction. |
|
|
69 | - make readahead emulation behave more like actual readahead by never failing. |
|
|
70 | - added EIO_LSEEK (untested). |
|
|
71 | - added EIO_FALLOC_FL_PUNCH_HOLE. |
|
|
72 | - wtf. etp_proc returned 0, and no compiler ever complained. |
|
|
73 | - remove pread/pwrite emulation, as the only system that lacked them |
|
|
74 | (cygwin) provides them for a while now. |
