48 | |
|
|
49 | - another workaround for the low-quality musl libc. |
|
|
50 | - test for umount seperately, as it is more portable. |
|
|
51 | - some low-quality posix attempts (openbsd, osx) declare the availability |
|
|
52 | of fexecve but then don't even bother to implemnent a stub. |
|
|
53 | |
|
|
54 | 4.79 Sun 25 Sep 2022 18:25:53 CEST |
|
|
55 | - the autoconf result of the mount check was not used, so it failed to |
|
|
56 | compile on most systems (reported by crackoff@tutanota.com). |
|
|
57 | - work around fedora not having a working C compiler setup by design |
|
|
58 | (reported by Paul Howarth). |
|
|
59 | |
|
|
60 | 4.78 Tue 06 Sep 2022 12:54:43 CEST |
|
|
61 | - add IO::AIO::mount and IO::AIO::umount. |
|
|
62 | - add a bunch of symbols from sys/mount.h. |
|
|
63 | |
|
|
64 | 4.77 Mon 05 Sep 2022 02:03:38 CEST |
|
|
65 | - add MFD_HUGETLB_2MB and MFD_HUGETLB_1GB constants. |
|
|
66 | - add fexecve. |
|
|
67 | - add lots of missing functions to @EXPORT_OK. |
|
|
68 | |
|
|
69 | 4.76 Tue Jul 27 20:45:01 CEST 2021 |
|
|
70 | - add autoconf test for siginfo_t, which is, of course, not |
|
|
71 | available on windows (reported by Peter Petky). |
|
|
72 | - disable syscalls on solaris, as perl seems to provide an |
|
|
73 | incompatible syscall prototype that clashes with sys/syscall.h. |
|
|
74 | - add MAP_FIXED_NOREPLACE, MAP_SHARED_VALIDATE, MAP_SYNC and |
|
|
75 | MAP_UNINITIALIZED. |
|
|
76 | |
|
|
77 | 4.75 Wed Dec 30 08:44:55 CET 2020 |
|
|
78 | - removed leftover debug output from treescan. |
|
|
79 | - added (but not documented) waitid-P_*, FSPICK_*, FSOPEN_*, |
|
|
80 | FSCONFIG_*, MOUNT_ATTR_* constants. |
|
|
81 | |
|
|
82 | 4.74 Tue Dec 29 16:19:28 CET 2020 |
|
|
83 | - added pidfd_open, pidfd_getfd and pidfd_send_signal functions. |
|
|
84 | - rework bin/treescan to avoid recursion. This fixes two bugs |
|
|
85 | where a deep directory traversal or a lot of command line |
|
|
86 | arguments could cause it to crash. |
|
|
87 | - added (but not documented) open_tree, AT_* and move_mount flags. |
|
|
88 | - support defining syscall numbers in gendef0. |
|
|
89 | |
|
|
90 | 4.73 Fri Dec 4 02:08:37 CET 2020 |
|
|
91 | - def0.h was not uptodate, running into musl problems |
|
|
92 | (reported by B Fraser). |
|
|
93 | - IO::AIO::splice and IO::AIO::tee didn't properly return |
|
|
94 | 64 bit values. |
|
|
95 | - added IO::AIO::accept4. |
|
|
96 | - add various F_SEAL related fcntl constants. |
|
|
97 | - removed experimental marker for fdlimit functions. |
|
|
98 | - fiemap now includes the last segment even if it overflows |
|
|
99 | the end offset, which is arguably the correct behaviour. |
|
|
100 | |
|
|
101 | 4.72 Wed Apr 3 04:56:03 CEST 2019 |
|
|
102 | - (libeio) if fd 0 is available do not use it for aio_wd, as it |
|
|
103 | collides with IO::AIO::CWD. |
|
|
104 | - added IO::AIO::memfd_create. |
|
|
105 | - correctly include <sys/uio.h> in the vmsplice test. |
|
|
106 | - reduce codesize by ~7% on amd64 by declaring more functions |
|
|
107 | as noinline. |
|
|
108 | - documentation fixes and updates. |
|
|
109 | - experimental and undocumented preliminary support for synchronous statx. |
|
|
110 | |
|
|
111 | 4.71 Sun Mar 10 13:09:26 CET 2019 |
|
|
112 | - due to an error in the linux manpages, the configure tests |
|
|
113 | for readahead, sync_file_range, splice etc. failed. This has been fixed. |
|
|
114 | |
|
|
115 | 4.7 Mon Mar 4 11:28:13 CET 2019 |
|
|
116 | - majorly speed up scandir for the very special case of a non-POSIX |
|
|
117 | filesystem that nevertheless reports valid dt_type information. |
|
|
118 | The only known filesystem of this type is currently btrfs, which |
|
|
119 | didn't get it's act together to implement POSIX semantics in all |
|
|
120 | these years, and I am tired of waiting. |
|
|
121 | - add IO::AIO::MCL_ONFAULT for mlockall, add IO::AIO::mlockall. |
|
|
122 | - neither sys/mkdev.h nor sys/sysmacros.h were included, even when they |
|
|
123 | were detected by autoconf. |
|
|
124 | |
|
|
125 | 4.6 Sat Aug 25 21:58:36 CEST 2018 |
|
|
126 | - add st_btime, st_btimesec, st_btimensec and st_gen accessors, |
|
|
127 | mostly for bsds which expose birthtime and st_gen members (netbsd, freebsd |
|
|
128 | but only st_gen on openbsd because they compiled their perl without support |
|
|
129 | for birthtimes). |
|
|
130 | - fix madvise and munlock to properly support negative offsets. |
|
|
131 | - allocate fd for the aio_close at boot time, to guarantee it working |
|
|
132 | later, rather than calling abort when it fails. also avoids |
|
|
133 | close-on-exec race issues after module load. |
|
|
134 | - #undef utime on win32, maybe this helps some reports of utime hangs. |
|
|
135 | - minor doc improvements. |
|
|
136 | - minor configure cleanups. |
|
|
137 | - use $Config{perllibs} instead of libs for configure. might help people |
|
|
138 | who didn't install all perl dependencies (might break things as well). |
|
|
139 | |
|
|
140 | 4.54 Tue Aug 14 13:54:48 CEST 2018 |
|
|
141 | - include sys/mkdev.h or sys/sysmacros.h if available. |
|
|
142 | - further tweaks to configure invocation for systems requiring --rpath. |
|
|
143 | - no longer rely on custom paths on win32 platforms. |
|
|
144 | - try to work around buggy PAGESIZE macro on solaris. |
|
|
145 | |
|
|
146 | 4.53 Tue Aug 14 11:27:50 CEST 2018 |
|
|
147 | - add $Config{libs} to LIBS for configure, to work around systems |
|
|
148 | with broken library dependencies (... openbsd). |
|
|
149 | |
|
|
150 | 4.52 Sun Aug 12 08:09:45 CEST 2018 |
|
|
151 | - config.h.in was missing in distribution. |
|
|
152 | |
|
|
153 | 4.51 Sun Aug 12 07:24:14 CEST 2018 |
|
|
154 | - complete rework of the autoconf framework: IO::AIO now uses its own |
|
|
155 | config.h, separate from libeio, and tries to test the actual perl |
|
|
156 | environment, not the standard system environment. |
|
|
157 | - provide nanosecond-accracy stat time accessors for both perl and IO::AIO |
|
|
158 | stat functions. |
|
|
159 | - removed non-portable C++ syntax from eio.c. |
|
|
160 | - try to fix readdir tests on cygwin spuriously failing. |
|
|
161 | |
|
|
162 | 4.5 Wed Aug 1 00:23:55 CEST 2018 |
|
|
163 | - aio_mtouch touch all pages as requested, not just the first page in most cases. |
|
|
164 | - new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE |
|
|
165 | and MREMAP_FIXED. |
|
|
166 | - add O_ACCMODE. |
|
|
167 | - add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants. |
|
|
168 | |
|
|
169 | 4.4 Tue Feb 20 07:54:12 CET 2018 |
|
|
170 | - new aio_slurp request. |
|
|
171 | - add (experimental) IO::AIO::eventfd and timerfd* function. |
|
|
172 | - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit. |
|
|
173 | - point out that aio_copy overwrites existing files. |
|
|
174 | - removed filesystem magic number table from aio_statvfs docs as |
|
|
175 | statvfs doesn't actually return this info at all (statfs does). |
|
|
176 | - add a bunch of (mostly linux-specific) constants for use in ioctls |
|
|
177 | (see aio_ioctl docs). |
|
|
178 | - treescan now has a proper manpage and useful --help output. |
|
|
179 | - new option --sync in treescan, to sync everything in a subtree. |
|
|
180 | - changed default for aio_msync flags to MSYNC_SYNC. |
|
|
181 | - document offset/length behaviour of mprotect/madvise. |
|
|
182 | - support linux's renameat2 (via aio_rename2). |
|
|
183 | - add aio_rename2, an aio_rename with flags. |
|
|
184 | - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants. |
|
|
185 | - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE. |
|
|
186 | - (libeio) use posix_close if available. |
|
|
187 | - (libeio) internal close() calls no longer disturb errno. |
|
|
188 | - add IO:AIO::FALLOC_FL_UNSHARE. |
|
|
189 | - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES |
|
|
190 | and better eventfd detection. |
|
|
191 | |
|
|
192 | 4.34 Sun May 1 19:18:24 CEST 2016 |
|
|
193 | - def0.h was not properly generated during previous release, causing |
|
|
194 | compile errors on various platforms. |
|
|
195 | - major/minor were accidentally switched (reported by Alexander Lishenyuk). |
|
|
196 | - removed duplicate definition of MAP_HUGETLB, that was found due to |
|
|
197 | a bug in Perl::Tidy (testcase by alaska332@gmail.com). |
|
|
198 | - added (untested!) aio_fcntl, aio_ioctl requests. |
|
|
199 | - (libeio) names set via prctl are truncated to 15 chars + nul, not 16, |
|
|
200 | as manpages-dev originally claimed. |
|
|
201 | |
|
|
202 | 4.33 Mon Jan 18 12:50:10 CET 2016 |
|
|
203 | - add IO::AIO::pipe2 function. |
|
|
204 | - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE |
|
|
205 | constants. |
|
|
206 | - added support for O_TMPFILE and O_PATH constants. |
|
|
207 | - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK |
|
|
208 | consdtants, whether they can be sensibly used or not. |
|
|
209 | - use NO_INIT where applicable. |
|
|
210 | - update libecb. |
|
|
211 | - added stability canary support. |
|
|
212 | - updated linux super magic table to 4.3.3. |
|
|
213 | |
|
|
214 | 4.32 Wed Feb 11 20:32:11 CET 2015 |
|

|
|
216 | user-visible changes. |

|
218 | |

219 | 4.31 Tue Jun 3 03:29:27 CEST 2014 |
|
|
220 | - work around more 5.20 bugs. backwards compatibility my ass. |
|
|
221 | |
|
|
222 | 4.3 Fri Apr 11 06:22:38 CEST 2014 |
|
|
223 | - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL |
|
|
224 | without warning by switching the meaning of USE_SOCKETS_AS_HANDLES |
|
|
225 | in 5.18. What's so attractive about giving a shit about backwards |
|
|
226 | compatibility - I will never understand. |
|
|
227 | |
|
|
228 | 4.2 Sat Jan 25 01:13:14 CET 2014 |
|
|
229 | - aio_group could corrupt memory because it didn't restore |
|
|
230 | the stack after req_submit. |

|
|
237 | |
|
|
238 | 4.19 Sun Jan 6 12:47:26 CET 2013 |
|
|
239 | - avoid endless loop in fiemap with some XFS files. |
|
|
240 | - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."] |
|
|
241 | and call rename/rmdir instead of renameat/unlinkat. |
|
|
242 | |
|
|
243 | 4.18 Thu Oct 11 07:01:26 CEST 2012 |
|
|
244 | - fix unintended xthread_create by intentionalising it :) |

|
245 | |
|
|
246 | 4.17 Thu Oct 11 05:19:47 CEST 2012 |

|
|
251 | as per unix spec. |
|
|
252 | |
|
|
253 | 4.16 Tue Aug 14 05:39:03 CEST 2012 |
|
|
254 | - aio_statvfs was wromgly marked for wd emulation, causing |
