44 | - IO::AIO::splice and IO::AIO::tee didn't properly return |
|
|
45 | 64 bit values. |
|
|
46 | - added IO::AIO::accept4. |
|
|
47 | - add various F_SEAL related fcntl constants. |
|
|
48 | |
|
|
49 | 4.72 Wed Apr 3 04:56:03 CEST 2019 |
|
|
50 | - (libeio) if fd 0 is available do not use it for aio_wd, as it |
|
|
51 | collides with IO::AIO::CWD. |
|
|
52 | - added IO::AIO::memfd_create. |
|
|
53 | - correctly include <sys/uio.h> in the vmsplice test. |
|
|
54 | - reduce codesize by ~7% on amd64 by declaring more functions |
|
|
55 | as noinline. |
|
|
56 | - documentation fixes and updates. |
|
|
57 | - experimental and undocumented preliminary support for synchronous statx. |
|
|
58 | |
|
|
59 | 4.71 Sun Mar 10 13:09:26 CET 2019 |
|
|
60 | - due to an error in the linux manpages, the configure tests |
|
|
61 | for readahead, sync_file_range, splice etc. failed. This has been fixed. |
|
|
62 | |
|
|
63 | 4.7 Mon Mar 4 11:28:13 CET 2019 |
|
|
64 | - majorly speed up scandir for the very special case of a non-POSIX |
|
|
65 | filesystem that nevertheless reports valid dt_type information. |
|
|
66 | The only known filesystem of this type is currently btrfs, which |
|
|
67 | didn't get it's act together to implement POSIX semantics in all |
|
|
68 | these years, and I am tired of waiting. |
|
|
69 | - add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall. |
|
|
70 | - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they |
|
|
71 | were detected by autoconf. |
|
|
72 | |
|
|
73 | 4.6 Sat Aug 25 21:58:36 CEST 2018 |
|
|
74 | - add st_btime, st_btimesec, st_btimensec and st_gen accessors, |
|
|
75 | mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd |
|
|
76 | but only st_gen on openbsd because they compiled their perl without support |
|
|
77 | for birthtimes). |
|
|
78 | - fix madvise and munlock to properly support negative offsets. |
|
|
79 | - allocate fd for the aio_close at boot time, to guarantee it working |
|
|
80 | later, rather than calling abort when it fails. also avoids |
|
|
81 | close-on-exec race issues after module load. |
|
|
82 | - #undef utime on win32, maybe this helps some reports of utime hangs. |
|
|
83 | - minor doc improvements. |
|
|
84 | - minor configure cleanups. |
|
|
85 | - use $Config{perllibs} instead of libs for configure. might help people |
|
|
86 | who didn't install all perl dependencies (might break things as well). |
|
|
87 | |
|
|
88 | 4.54 Tue Aug 14 13:54:48 CEST 2018 |
|
|
89 | - include sys/mkdev.h or sys/sysmacros.h if available. |
|
|
90 | - further tweaks to configure invocation for systems requiring --rpath. |
|
|
91 | - no longer rely on custom paths on win32 platforms. |
|
|
92 | - try to work around buggy PAGESIZE macro on solaris. |
|
|
93 | |
|
|
94 | 4.53 Tue Aug 14 11:27:50 CEST 2018 |
|
|
95 | - add $Config{libs} to LIBS for configure, to work around systems |
|
|
96 | with broken library dependencies (... openbsd). |
|
|
97 | |
|
|
98 | 4.52 Sun Aug 12 08:09:45 CEST 2018 |
|
|
99 | - config.h.in was missing in distribution. |
|
|
100 | |
|
|
101 | 4.51 Sun Aug 12 07:24:14 CEST 2018 |
|
|
102 | - complete rework of the autoconf framework: IO::AIO now uses its own |
|
|
103 | config.h, separate from libeio, and tries to test the actual perl |
|
|
104 | environment, not the standard system environment. |
|
|
105 | - provide nanosecond-accracy stat time accessors for both perl and IO::AIO |
|
|
106 | stat functions. |
|
|
107 | - removed non-portable C++ syntax from eio.c. |
|
|
108 | - try to fix readdir tests on cygwin spuriously failing. |
|
|
109 | |
|
|
110 | 4.5 Wed Aug 1 00:23:55 CEST 2018 |
|
|
111 | - aio_mtouch touch all pages as requested, not just the first page in most cases. |
|
|
112 | - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE |
|
|
113 | and MREMAP_FIXED. |
|
|
114 | - add O_ACCMODE. |
|
|
115 | - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants. |
|
|
116 | |
|
|
117 | 4.4 Tue Feb 20 07:54:12 CET 2018 |
|
|
118 | - new aio_slurp request. |
|
|
119 | - add (experimental) IO::AIO::eventfd and timerfd* function. |
|
|
120 | - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit. |
|
|
121 | - point out that aio_copy overwrites existing files. |
|
|
122 | - removed filesystem magic number table from aio_statvfs docs as |
|
|
123 | statvfs doesn't actually return this info at all (statfs does). |
|
|
124 | - add a bunch of (mostly linux-specific) constants for use in ioctls |
|
|
125 | (see aio_ioctl docs). |
|
|
126 | - treescan now has a proper manpage and useful --help output. |
|
|
127 | - new option --sync in treescan, to sync everything in a subtree. |
|
|
128 | - changed default for aio_msync flags to MSYNC_SYNC. |
|
|
129 | - document offset/length behaviour of mprotect/madvise. |
|
|
130 | - support linux's renameat2 (via aio_rename2). |
|
|
131 | - add aio_rename2, an aio_rename with flags. |
|
|
132 | - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants. |
|
|
133 | - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE. |
|
|
134 | - (libeio) use posix_close if available. |
|
|
135 | - (libeio) internal close() calls no longer disturb errno. |
|
|
136 | - add IO:AIO::FALLOC_FL_UNSHARE. |
|
|
137 | - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES |
|
|
138 | and better eventfd detection. |
|
|
139 | |
|
|
140 | 4.34 Sun May 1 19:18:24 CEST 2016 |
|
|
141 | - def0.h was not properly generated during previous release, causing |
|
|
142 | compile errors on various platforms. |
|
|
143 | - major/minor were accidentally switched (reported by Alexander Lishenyuk). |
|
|
144 | - removed duplicate definition of MAP_HUGETLB, that was found due to |
|
|
145 | a bug in Perl::Tidy (testcase by alaska332@gmail.com). |
|
|
146 | - added (untested!) aio_fcntl, aio_ioctl requests. |
|
|
147 | - (libeio) names set via prctl are truncated to 15 chars + nul, not 16, |
|
|
148 | as manpages-dev originally claimed. |
|
|
149 | |
|
|
150 | 4.33 Mon Jan 18 12:50:10 CET 2016 |
|
|
151 | - add IO::AIO::pipe2 function. |
|
|
152 | - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE |
|
|
153 | constants. |
|
|
154 | - added support for O_TMPFILE and O_PATH constants. |
|
|
155 | - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK |
|
|
156 | consdtants, whether they can be sensibly used or not. |
|
|
157 | - use NO_INIT where applicable. |
|
|
158 | - update libecb. |
|
|
159 | - added stability canary support. |

163 | - replace off_t by STRLEN where appropriate, should not result in |
|
|
164 | user-visible changes. |

|
|
168 | - work around more 5.20 bugs. backwards compatibility my ass. |
|
|
169 | |
|
|
170 | 4.3 Fri Apr 11 06:22:38 CEST 2014 |
|
|
171 | - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL |
|
|
172 | without warning by switching the meaning of USE_SOCKETS_AS_HANDLES |
|
|
173 | in 5.18. What's so attractive about giving a shit about backwards |
|
|
174 | compatibility - I will never understand. |
|
|
175 | |
|
|
176 | 4.2 Sat Jan 25 01:13:14 CET 2014 |
|
|
177 | - aio_group could corrupt memory because it didn't restore |
|

|
185 | |
|
|
186 | 4.19 Sun Jan 6 12:47:26 CET 2013 |
|
|
187 | - avoid endless loop in fiemap with some XFS files. |
|
|
188 | - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."] |
|
|
189 | and call rename/rmdir instead of renameat/unlinkat. |
|

201 | 4.16 Tue Aug 14 05:39:03 CEST 2012 |
|
|
202 | - aio_statvfs was wromgly marked for wd emulation, causing |
|
|
203 | it to malfunction for paths. |
|
|
204 | - fix a crash in aio_fiemap, when used on ranges without any |
|
|
205 | extents. |
|
|
206 | - work around linux kernel bug (at least in 3.2): kernel might |
|
|
207 | trash fiemap input arguments. |
|
|
208 | - work around linux kernel bug (at least in 3.2): kernel does not |
|
|
209 | set FIEMAP_EXTENT_LAST on last segment. |
|

|
|
211 | truncates segment count if a file. |

212 | - make fh argument of IO::AIO::mmap optional, also add mmap/munmap |
|
|

|
|
221 | - always include linux/types.h for fiemap, for compatibility to |
|
|
222 | ancient systems (Paul Howarth). |
|

|
|
224 | - provide SEEK_HOLE and SEEK_DATA, if available. |
|
|
225 | - work around (again!) an immensely stupid bug in RHEL, defining |
|
|
226 | autoconf macros in linux system headers (analysed by Paul Howarth). |
|
|
227 | |
|
|
228 | 4.14 Sat Apr 7 02:45:18 CEST 2012 |
|
|
229 | - fix stat structure usage on windows, which caused bogus stat results. |
