* Add support for USB bulk streams on Linux and Mac OS X (#11)
* Windows: Add AMD and Intel USB-3.0 root hub support
* Windows: Fix USB 3.0 speed detection on Windows 8 or later (#10)
* Added Russian translation for libusb_strerror strings
* All: Various small fixes and cleanups
The (#xx) numbers are libusb issue numbers, see ie:
https://github.com/libusb/libusb/issues/11
2014-01-25: v1.0.18
* Fix multiple memory leaks
* Fix a crash when HID transfers return no data on Windows
* Ensure all pending events are consumed
* Improve Android and ucLinux support
* Multiple Windows improvements (error logging, VS2013, VIA xHCI support)
* Multiple OS X improvements (broken compilation, SIGFPE, 64bit support)
2013-09-06: v1.0.17
* Hotplug callbacks now always get passed a libusb_context, even if it is
the default context. Previously NULL would be passed for the default context,
but since the first context created is the default context, and most apps
use only 1 context, this meant that apps explicitly creating a context would
still get passed NULL
* Android: Add .mk files to build with the Android NDK
* Darwin: Add Xcode project
* Darwin: Fix crash on unplug (#121)
* Linux: Fix hang (deadlock) on libusb_exit

* OpenBSD: Update OpenBSD backend with support for control transfers to
non-ugen(4) devices and make get_configuration() no longer generate I/O.
Note that using this libusb version on OpenBSD requires using
OpenBSD 5.3-current or later. Users of older OpenBSD versions are advised
to stay with the libusb shipped with OpenBSD (mpi)
* Windows: fix libusb_dll_2010.vcxproj link errors (#129)

2012-09-26: v1.0.14
* Reverts the previous API change with regards to bMaxPower.
If this doesn't matter to you, you are encouraged to keep using v1.0.13,
as it will use the same attribute as v2.0, to be released soon.
* Note that LIBUSB_API_VERSION is *decreased* to 0x010000FF and the previous
guidelines with regards to concurrent use of MaxPower/bMaxPower still apply.
2012-09-20: v1.0.13
* [MAJOR] Fix a typo in the API with struct libusb_config_descriptor where
MaxPower was used instead of bMaxPower, as defined in the specs. If your
application was accessing the MaxPower attribute, and you need to maintain
compatibility with libusb or older versions, see APPENDIX A below.

http://linux-hotplug.sourceforge.net
* Add libusb0 (libusb-win32) and libusbK driver support on Windows. Note that while
the drivers allow it, isochronous transfers are not supported yet in libusb. Also
not supported yet is the use of libusb-win32 filter drivers on composite interfaces

* Add toggleable debug, using libusb_set_debug() or the LIBUSB_DEBUG environment variable
* Define log levels in libusb.h and set timestamp origin to first libusb_init() call
* All logging is now sent to to stderr (info was sent to stdout previously)
* Update log messages severity and avoid polluting log output on OS-X

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
APPENDIX A - How to maintain code compatibility with versions of libusb and
libusb that use MaxPower:
If you must to maintain compatibility with versions of the library that aren't
using the bMaxPower attribute in struct libusb_config_descriptor, the
recommended way is to use the new LIBUSB_API_VERSION macro with an #ifdef.
For instance, if your code was written as follows:
if (dev->config[0].MaxPower < 250)
Then you should modify it to have:
#if defined(LIBUSB_API_VERSION) && (LIBUSB_API_VERSION >= 0x01000100)
if (dev->config[0].bMaxPower < 250)
#else
if (dev->config[0].MaxPower < 250)
#endif
The Documenter's Workbench (DWB) Release 3.3 is AT&T's original software
distribution of nroff and troff (ditroff), the preprocessors tbl, eqn, pic,
and grap, and the macro packages man, ms, and mm.

* innxmit: tidy up GetMessageID buffer handling In theory, if you
could get a message with an empty message-id header through
before anything else, it would call memcpy(NULL, p, 0) which
(surprisingly) has undefined behavior. This doesn't seem a very
likely contingency but I tidied up the code to avoid it and
(hopefully) be clearer anyway.
Thanks to Richard Kettlewell for the patch.
* storage/cnfs/cnfs.c: don't read uninitialised cycbuffname
Thanks to Richard Kettlewell for the patch.
2015-05-17 iulius
* Fixed alignment issues when storing values
2015-05-14 iulius
* Add Richard Kettlewell as a contributor
* Correct remap check in tradindexed lookup
The check was off by one; and when it happened, it invalidated
the 'parent' pointer, causing a use-after-munmap (or
use-after-free) condition.
Thanks to Richard Kettlewell for the bug report.
* Correctly flush CNFS buffers when nfswriter is true in inn.conf
* Correct remap check in tradindexed group lookup
Previously the remap check had an off-by-one bug and moreover
would never be done due to the loop condition (making the
off-by-one bug moot).
This one could be a problem in real life; if creating a group
causes innd to expand the index then an already-running nnrpd
will not automatically notice, and so won't be able to find the
group.
Thanks to Richard Kettlewell for the patch.
* nnrpd/commands.c: paranoid checking of AUTHINFO GENERIC reply
Check the number of arguments returned by AUTHINFO GENERIC.
Thanks to Richard Kettlewell for the patch.
* innfeed/connection.c: avoid violating C aliasing rules
The object was written as a 'struct sockaddr' but then read as a
'struct sockaddr_storage', which violates C99 s6.5#7. The fix is
to always access it as a 'struct sockaddr' and use a union to
ensure enough space for any possible address type.
Thanks to Richard Kettlewell for the patch.
* nnrpd/commands.c: correct sense of PERMgeneric reply
The comment has always been wrong, as well as the return value
for ~15 years...
Thanks to Richard Kettlewell for the patch.
* nnrpd/perm.c: don't dereference a null pointer if there are no
access groups
Thanks to Richard Kettlewell for the patch.
* nnrpd/article.c: A wrong variable was used for vhost feature.
Since these are created by the local innd, the error should not
normally occur.
Thanks to Richard Kettlewell for the patch.
* Verify that setuid() and setgid() actually succeed
See: https://lwn.net/Articles/451985/ for a discussion of the
issues in this area.
The checks in newuser.c are probably unnecessary due to the
subsequent tests. rnews.c is straight-up broken though.
Thanks to Richard Kettlewell for the patch.
2015-05-02 iulius
* expire/fastrm.c: Fix a dereferencing issue
* configure.ac: Build fix for current Mac OS X versions
The build was failing with recent versions of Mac OS X:
clang: error: no such file or directory:
'/usr/local/news/lib/libinn.3.dylib' make[1]: *** [libinn.la]
Error 1 make: *** [all-lib] Error 2
The reason is the '-multiply_defined'-part of the command line.
This switch is marked as obsolete in ld(1):
-multiply_defined treatment Previously provided a way to warn or
error if any of the sym- bols used from a dynamic library were
also available in another linked dynamic library. This option is
obsolete.
Thanks to Dennis Preiser for the report.
* innfeed/imap_connection.c: fix support of Cyrus SASL 2.1.25 and
later
Fix how sasl_callback_ft, added with Cyrus SASL 2.1.25, was
handled by innfeed. See revision [9381] for more information.
Thanks to Dennis Preiser for the report.
* innd/art.c: Fix a dereferencing issue when parsing
Injection-Info: header field
Thanks to David Binderman for the patch.
2015-05-01 iulius
* Bump version number in FAQ for new INN 2.5.5 release
Also remove link to Elena Samsonova's web site that appears to be
defunct.
2015-04-23 iulius
* mailpost: add new -t flag to specify the default temporary
directory
Check that the database directory and the temporary directory are
writable when mailpost is run, and otherwise die with an error.
Two paths are now tried by default for the temporary directory:
pathtmp, and then /var/tmp if pathtmp is not writable.
* Fix GCC 5.1.0 warning for incompatible pointer type
Rename the "U" macro used by two tests to "SUC" (casting to
String of Unsigned Chars) because it otherwise conflicts with how
Unicode strings are declared in ISO C11, the new default mode for
the GCC 5 series.
2015-04-20 iulius
* Update TODO with references to existing patches
2015-04-05 iulius
* Mention required TLS ciphers for interoperability
* Update TODO with current state of INN 2.6.0
2015-04-02 iulius
* Update changelog to mention other changes for INN 2.5.5
* Use Sys::Hostname Perl core module instead of calling
/bin/hostname
2015-03-24 iulius
* Add two missing contrib programs in the exceptions of mkmanifest
* Typo in POD formatting
* Update copyright years (add 2015)
* Update config.guess and config.sub to upstream versions from
2015-03-08
* Update control.ctl to upstream version from 2014-06-17
2015-03-21 iulius
* scanlogs: Limit the number of lines to show from error log files
When lots of lines are present in error log files, they appear in
the news.daily verbatim, and the resulting email is so large it
is bouncing.
Restrict the number of lines to 50 (the default value for unknown
lines from news.notice).
Thanks to Jeffrey M. Vinocur for the bug report.
* nnrpd: Count write time stats when using SASL
* Improve the count of sleeping channels
The highest file descriptor of sleeping channels was not always
properly updated. A new CHANresetlastsleeping() function now does
the job when called.
Also prevent innd from crashing if a channel is supposed to sleep
but does not have a Waker set.
Thanks to Petr Novopashenniy for the bug report.
* readers.conf: improve the first example to disambiguate its
effect against loca l connections
2015-03-18 iulius
* pullnews: when giving a port along with a server name, check
there is only one ":"
Otherwise, it is very likely that the given server name is an
IPv6 address, and therefore its end should not be interpreted as
a port.
2015-01-21 iulius
* Fix the unsignedness of TMRgettime when printed
2015-01-10 eagle
* http://www.imc.org/ietf-usefor/ appears to be gone
Replace this link in HACKING with a link to the usefor mailing
list archives and to my Usenet article format pages.
2015-01-10 iulius
* Do not mention that TLS compression will be disabled in the next
INN release
As the CRIME attack is not exploitable in NNTP, disabling TLS
compression by default is pointless. No vulnerability in TLS
compression is currently known as far as NNTP is concerned.
* Add a cast to fix a gcc warning
2015-01-07 iulius
* Regenerate Makefile dependencies with gcc 4.7.2
Also adapt support/makedepend to keep the two leading spaces, as
in previous versions of gcc.
Backport commit [9566].
* Cleanup in include stuff
- Add missing BEGIN_DECLS/END_DECLS, and also use them instead of
their expansion.
- Add missing inclusion of <inn/defines.h>.
2015-01-04 eagle
* Remove dead link to nnrpkrb5auth
2014-12-16 iulius
* nnrp.access2readers.conf: add default username when none is
specified
2014-12-14 iulius
* Add new contrib/nnrp.access2readers.conf.in script
This script converts old-style nnrp.access to readers.conf.
Thanks to Jeffrey M. Vinocur for his contribution.
2014-12-07 iulius
* Update Russ's mail address
* Fix typos
2014-12-01 iulius
* Add support for choosing the elliptic curve to use with TLS
support
The new tlseccurve parameter in inn.conf takes the name of a
curve OpenSSL knows about, to use for ephemeral key exchanges.
Thanks to Christian Mock for the patch.
2014-11-23 iulius
* m4/sendmail.m4: add missing brackets
The configure script was failing when running that part of code.
2014-11-12 iulius
* inn.conf: Improve documentation about tlsprotocols and
tlscompression
2014-11-11 iulius
* Improve tuning of the SSL/TLS configuration
nnrpd's TLS support is basically using OpenSSL's defaults WRT
issues such as protocol support and cipher suites. In these days
of POODLEs and other vulnerabilities, it should be useful to be
able to have better control over what's offered. So this patch
adds a few options to inn.conf:
- tlsprotocols: allows to select the SSL/TLS versions that are
supported
- tlsciphers: allows to give an OpenSSL cipher string to tailor
the cipher suites that are offered to clients
- tlspreferserverciphers: switches on the server-side selection
of the cipher suite (TLS default is "client chooses")
- tlscompression: allows to turn off TLS compression (because of
the CRIME attack) if the OpenSSL version supports this.
Many thanks to Christian Mock for his patch.
2014-11-09 iulius
* Mention PyClean as a Python-based variant of Cleanfeed.
2014-10-28 iulius
* Update default paths for Debian and Fedora
* Fix a dependency in a build rule
2014-10-03 iulius
* innwatch: report an error when the control file is missing
2014-09-24 iulius
* rc.news: no longer explicitly sleep before starting innwatch and
cnfsstat
Instead, make these two scripts sleep by themselves.
Also update documentation: improve the list of actions done by
rc.news, and no longer mentions that innd should be throttled
before being stopped (this is not true - the shutdown process
already does the actions throttling does).
* innwatch: add -i flag to specify how many seconds to sleep at
startup
- Also fix previous commit [9651] that did not totally fix the
issue it was supposed to fix.
- Fix the behaviour of the -f flag (it wasn't doing anything).
- Fix how the -l flag was parsed (a space was required between -l
and its argument, whils it should not have been required).
- Add new POD documentation for innwatch, and update it at the
same time: document new -i flag, and document already existing -f
flag.
* cnfsstat: add -i flag to specify how many seconds to sleep at
startup
Update documentation, and homogenize POD syntax at the same time.
2014-09-24 eagle
* Re-add second $(LIBSTORAGE) when linking backends
Backend commands (such as nntpget) linked with both history and
storage libraries list $(LIBSTORAGE) in the link line twice. This
isn't a mistake; there are some unfortunate circular dependencies
that require listing $(LIBSTORAGE) both before and after
$(LIBINNHIST) in the link line or static linking will fail.
2014-09-22 iulius
* Fix build issues on AIX 7.1
mmap is redefined to mmap64 when large file support is enabled.
2014-09-21 iulius
* Fixed a warning and an unnecessary sys/stropts.h header
* Typos
* Fix build of contrib/respool.c
Remove an unused variable.
Add a link to libhistory.
* Fix build of contrib/reset-cnfs.c
Add correct include header files.
Use the right DO_LARGEFILES variable instead of LARGE_FILES.
Reformat the code (remove tabulations).
Properly exit with the right status code.
* Fix a few warnings, and update svn:ignore for contrib
* Fix build of contrib/expirectl.c
Add correct include header files, and fix a few warnings in
printf() calls.
Add portability code for statfs/statvfs support.
* Add compilation rules for contrib/auth_pass.c and
contrib/expirectl.c
Use the right socklen_t type, and add crypt.h header if
available.
* FAQ: add how to feed articles arrived between two dates to
another server
2014-09-11 iulius
* innupgrade: fix its execution
On a few systems like AIX, innupgrade failed to run during an
upgrade because "perl -T" was not explicitly called. Failure was:
"-T" is on the #! line, it must also be used on the command line
Thanks to The Doctor for his bug report.
2014-09-07 iulius
* Add missing dependency for libtest.o during the build of
nnrpd/auth-ext.t
2014-09-05 iulius
* Fix typos in INN_HAVE_SYS_BITYPES_H and
INN_MACRO_IN6_ARE_ADDR_EQUAL names
2014-08-30 iulius
* libinn documentation: update the name of the fdflag functions
* pullnews: improve logging when an error occurs during GROUP
Also rewrite a ternary condition to improve readability.
Patch from Geraint A. Edwards.
* pullnews: new -a flag (hashfeed ability)
Add a new feature to pullnews: hashfeed to split feeds. It uses
MD5 and is Diablo-compatible.
Thanks to Geraint Edwards for the patch.
* pullnews: new -B flag (header-only feeding)
Add a new feature to pullnews: header-only feeding.
If the article does not already have a Bytes: header field, one
is added. Bodies are kept only for control articles.
Thanks to Geraint Edwards for the patch.
* pullnews: bug fix to rnews when -O; improved rnews reporting
Thanks to Geraint Edwards for the patch.
* pullnews: improve wording
* When pullnews runs for the first time against a newsgroup, say
"never" instead of January, 1st 1970 as the last run date. *
Improve spaces, uppercase characters and singular forms when 1
article is retrieved. * Update the config file even when the
group is empty.
* pullnews: remove headers matching (or not) a given regexp
Enable the -m flag to remove headers matching (or not) a given
regexp.
Thanks to Geraint Edwards for the patch.
2014-08-09 iulius
* innwatch: no longer creates a child process for sleeping
innwatch creates a child process only for sleeping and then waits
on that process. The forked-off process is not killed by 'rc.news
stop' (only its parent is), and will only die after it's done
sleeping. If running under SMF on illumos/Solaris, this causes
the service to likely drop into maintenance state (since not all
processes die within timeout).
Thanks to Lauri Tirkkonen for the patch.
2014-06-04 iulius
* Bump version number to 2.5.5 for STABLE.
Imported to pkgsrc-wip by myself(nros).
Memphis is a library for OpenStreetMap written in C using eXpat,
Cairo and GLib. It's licensed under the terms of the GNU Lesser
General Public License.
Main changes since 3.4.0:
--disable-non-free configure option
Changed default language dialect from --std-sdcc89 to --std-sdcc99
Reorganized and updated manual
Reduced memory consumption (most noticeable for high --max-allocs-per-node)
Faster compilation for stm8 (most noticeable for high --max-allocs-per-node)
atoll() function for conversion of strings to long long
__z88dk_fastcall and __z88dk_callee calling conventions for more
efficient function calls and better compability with z88dk
--lospre-unsafe-read renamed to --allow-unsafe-read
Add new microchip devices
Extended error and warning messages.
Enabled the CONFIG directive on the 12-bit and 14-bit devices.
Enabled the IDLOCS directive on the pic18fxxx devices.
The gpasm lists the properties of the processors.
New predefined constants in the gpasm: __EEPROM_START, etc.
The gpdasm shows the names of SFRs and bits, in addition shows the labels
in code.
The inc and lkr files are synced with MPLABX 2.20
sysutils/py-attic, which is no longer being developed upstream.
BorgBackup (short: Borg) is a deduplicating backup program. Optionally,
it supports compression and authenticated encryption.
The main goal of Borg is to provide an efficient and secure way to
backup data. The data deduplication technique used makes Borg suitable
for daily backups since only changes are stored. The authenticated
encryption technique makes it suitable for backups to not fully trusted
targets.
File::Find::Object is an object-oriented and iterative replacement for
File::Find. I.e: it is a module for traversing a directory tree, and finding
all the files contained within it programatically.

This release now needs the previous one (lang/go14) to build.
The biggest developments in the implementation are:
* The compiler and runtime are now written entirely in Go (with a little
assembler). C is no longer involved in the implementation, and so the
C compiler that was once necessary for building the distribution is
gone.
* The garbage collector is now concurrent and provides dramatically
lower pause times by running, when possible, in parallel with other
goroutines.
* By default, Go programs run with GOMAXPROCS set to the number of cores
available; in prior releases it defaulted to 1.
* Support for internal packages is now provided for all repositories,
not just the Go core.
* The go command now provides experimental support for "vendoring"
external dependencies.
* A new go tool trace command supports fine-grained tracing of program
execution.
* A new go doc command (distinct from godoc) is customized for
command-line use.
Full release notes are at https://golang.org/doc/go1.5.
