|
26 | - aio_group could corrupt memory because it didn't restore |
|
|
27 | the stack after req_submit. |
|
|
28 | - work around changes in ExtUtils::MakeMaker. |
|
|
29 | - (libeio) implement aio_realpath for win32. |
|
|
30 | - (xthread) work around compile time bugs in ptw32. |

35 | - avoid endless loop in fiemap with some XFS files. |
|
|
36 | - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."] |
|

38 | |
|
|
39 | 4.18 Thu Oct 11 07:01:26 CEST 2012 |

|
|
45 | - work around a bug in btrfs' FIEMAP ioctl implementation. |
|
|

|
|
47 | as per unix spec. |
|
|
48 | |
|
|
49 | 4.16 Tue Aug 14 05:39:03 CEST 2012 |
|
|
50 | - aio_statvfs was wromgly marked for wd emulation, causing |
|
|
51 | it to malfunction for paths. |
|
|
52 | - fix a crash in aio_fiemap, when used on ranges without any |
|
|
53 | extents. |
|
|
54 | - work around linux kernel bug (at least in 3.2): kernel might |
|
|
55 | trash fiemap input arguments. |
|
|
56 | - work around linux kernel bug (at least in 3.2): kernel does not |
|
|
57 | set FIEMAP_EXTENT_LAST on last segment. |
|
|
58 | - work around linux kernel bug (at least in 3.2): kernel silently |
|
|
59 | truncates segment count if a file. |
|
|
60 | - make fh argument of IO::AIO::mmap optional, also add mmap/munmap |
|
|
61 | to quick overview. |
|
|
62 | - splice can corrupt data. |
|
|
63 | - (libeio) remove pread/pwrite emulation. |
|

64 | - do not grow mmaped scalars in aio_read. |
|
|
65 | - add FALLOC_FL_PUNCH_HOLE and document fallocate. |

|
|
67 | |
|
|
68 | 4.15 Tue Apr 10 06:59:00 CEST 2012 |
|
|
69 | - always include linux/types.h for fiemap, for compatibility to |
|
|
70 | ancient systems (Paul Howarth). |
|
|
71 | - experimental support for IO::AIO::splice and ::tee (no aio_...). |
|
|
72 | - provide SEEK_HOLE and SEEK_DATA, if available. |
|
|
73 | - work around (again!) an immensely stupid bug in RHEL, defining |
|
|
74 | autoconf macros in linux system headers (analysed by Paul Howarth). |
|
|
75 | |
|
|
76 | 4.14 Sat Apr 7 02:45:18 CEST 2012 |

|
83 | 4.12 Fri Dec 30 08:51:25 CET 2011 |
|
|
84 | - realpath would return a random value if the name was too long, |
|

87 | |
|
|
88 | 4.11 Mon Oct 10 00:24:11 CEST 2011 |

|
|
91 | 4.1 Sun Oct 9 10:24:11 CEST 2011 |
|
|
92 | - IO::AIO did access uninitialised memory on unsuccessful stats. |
|
|
93 | - (libeio) added syncfs syscall wrapper. |
|
|
94 | - (libeio) set thread name on linux (ps -L/Hcx, top, gdb). |

100 | - take advantage of working directoriy abstractions |
|
|
101 | in aio_scandir and treescan. |
|
|
102 | - reduce compiled size by ~10% by not inlining some key functionality. |

|
|
107 | see FORK BEHAVIOUR in manpage for details. |
|
|
108 | - passes testsuite on win32 now and may actually work |
|
|
109 | (activestate 5.10.1 / MSVC6, YMMV). |
|
|
110 | - (libeio) fix a deadlock where a wakeup signal could be missed when |
|
|
111 | a timeout occured at the same time. |
|
|
112 | - (libeio) added realpath. |
|
|
