42 | - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they |
|
|
43 | were detected by autoconf. |
|
|
44 | |
|
|
45 | 4.6 Sat Aug 25 21:58:36 CEST 2018 |
|
|
46 | - add st_btime, st_btimesec, st_btimensec and st_gen accessors, |
|
|
47 | mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd |
|
|
48 | but only st_gen on openbsd because they compiled their perl without support |
|
|
49 | for birthtimes). |
|
|
50 | - fix madvise and munlock to properly support negative offsets. |
|
|
51 | - allocate fd for the aio_close at boot time, to guarantee it working |
|
|
52 | later, rather than calling abort when it fails. also avoids |
|
|
53 | close-on-exec race issues after module load. |
|
|
54 | - #undef utime on win32, maybe this helps some reports of utime hangs. |
|
|
55 | - minor doc improvements. |
|
|
56 | - minor configure cleanups. |
|
|
57 | - use $Config{perllibs} instead of libs for configure. might help people |
|
|
58 | who didn'T install all perl dependencies (might break things as well). |
|
|
59 | |
|
|
60 | 4.54 Tue Aug 14 13:54:48 CEST 2018 |
|
|
61 | - include sys/mkdev.h or sys/sysmacros.h if available. |
|
|
62 | - further tweaks to configure invocation for systems requiring --rpath. |
|
|
63 | - no longer rely on custom paths on win32 platforms. |
|
|
64 | - try to work around buggy PAGESIZE macro on solaris. |
|
|
65 | |
|
|
66 | 4.53 Tue Aug 14 11:27:50 CEST 2018 |
|
|
67 | - add $Config{libs} to LIBS for configure, to work around systems |
|
|
68 | with broken library dependencies (... openbsd). |
|
|
69 | |
|
|
70 | 4.52 Sun Aug 12 08:09:45 CEST 2018 |
|
|
71 | - config.h.in was missing in distribution. |
|
|
72 | |
|
|
73 | 4.51 Sun Aug 12 07:24:14 CEST 2018 |
|
|
74 | - complete rework of the autoconf framework: IO::AIO now uses its own |
|
|
75 | config.h, separate from libeio, and tries to test the actual perl |
|
|
76 | environment, not the standard system environment. |
|
|
77 | - provide nanosecond-accracy stat time accessors for both perl and IO::AIO |
|
|
78 | stat functions. |
|
|
79 | - removed non-portable C++ syntax from eio.c. |
|
|
80 | - try to fix readdir tests on cygwin spuriously failing. |
|
|
81 | |
|
|
82 | 4.5 Wed Aug 1 00:23:55 CEST 2018 |
|
|
83 | - aio_mtouch touch all pages as requested, not just the first page in most cases. |
|
|
84 | - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE |
|
|
85 | and MREMAP_FIXED. |
|
|
86 | - add O_ACCMODE. |
|
|
87 | - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants. |
|
|
88 | |
|
|
89 | 4.4 Tue Feb 20 07:54:12 CET 2018 |
|
|
90 | - new aio_slurp request. |
|
|
91 | - add (experimental) IO::AIO::eventfd and timerfd* function. |
|
|
92 | - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit. |
|
|
93 | - point out that aio_copy overwrites existing files. |
|
|
94 | - removed filesystem magic number table from aio_statvfs docs as |
|
|
95 | statvfs doesn't actually return this info at all (statfs does). |
|
|
96 | - add a bunch of (mostly linux-specific) constants for use in ioctls |
|
|
97 | (see aio_ioctl docs). |
|
|
98 | - treescan now has a proper manpage and useful --help output. |
|
|
99 | - new option --sync in treescan, to sync everything in a subtree. |
|
|
100 | - changed default for aio_msync flags to MSYNC_SYNC. |
|
|
101 | - document offset/length behaviour of mprotect/madvise. |
|
|
102 | - support linux's renameat2 (via aio_rename2). |
|
|
103 | - add aio_rename2, an aio_rename with flags. |
|
|
104 | - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants. |
|
|
105 | - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE. |
|
|
106 | - (libeio) use posix_close if available. |
|
|
107 | - (libeio) internal close() calls no longer disturb errno. |
|
|
108 | - add IO:AIO::FALLOC_FL_UNSHARE. |
|
|
109 | - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES |
|
|
110 | and better eventfd detection. |
|
|
111 | |
|
|
112 | 4.34 Sun May 1 19:18:24 CEST 2016 |
|
|
113 | - def0.h was not properly generated during previous release, causing |
|
|
114 | compile errors on various platforms. |
|
|
115 | - major/minor were accidentally switched (reported by Alexander Lishenyuk). |
|
|
116 | - removed duplicate definition of MAP_HUGETLB, that was found due to |
|
|
117 | a bug in Perl::Tidy (testcase by alaska332@gmail.com). |
|
|
118 | - added (untested!) aio_fcntl, aio_ioctl requests. |
|
|
119 | - (libeio) names set via prctl are truncated to 15 chars + nul, not 16, |
|
|
120 | as manpages-dev originally claimed. |
|
|
121 | |
|
|
122 | 4.33 Mon Jan 18 12:50:10 CET 2016 |
|
|
123 | - add IO::AIO::pipe2 function. |
|
|
124 | - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE |
|
|
125 | constants. |
|
|
126 | - added support for O_TMPFILE and O_PATH constants. |
|
|
127 | - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK |
|
|
128 | consdtants, whether they can be sensibly used or not. |
|
|
129 | - use NO_INIT where applicable. |
|
|
130 | - update libecb. |

|
|
141 | |
|
|
142 | 4.3 Fri Apr 11 06:22:38 CEST 2014 |
|
|
143 | - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL |
|
|
144 | without warning by switching the meaning of USE_SOCKETS_AS_HANDLES |
|
|
145 | in 5.18. What's so attractive about giving a shit about backwards |
|
|
146 | compatibility - I will never understand. |
|
|
147 | |
|
|
148 | 4.2 Sat Jan 25 01:13:14 CET 2014 |
|
|
149 | - aio_group could corrupt memory because it didn't restore |
|

|
158 | 4.19 Sun Jan 6 12:47:26 CET 2013 |
|
|
159 | - avoid endless loop in fiemap with some XFS files. |
|
|
160 | - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."] |
|
|
161 | and call rename/rmdir instead of renameat/unlinkat. |
|
|
162 | |
|
|
163 | 4.18 Thu Oct 11 07:01:26 CEST 2012 |

|

|
|
177 | extents. |

|
|
179 | trash fiemap input arguments. |

|
|
181 | set FIEMAP_EXTENT_LAST on last segment. |
|
