POSIX message queues allow local processes to exchange data in the form
of messages. This API is distinct from that provided by System V
message queues, but provides similar functionality.
* Homepage: http://bogomips.org/ruby_posix_mq/
* public-inbox: ruby-posix-mq@bogomips.org
* git clone git://bogomips.org/ruby_posix_mq.git
* Atom feed: http://bogomips.org/ruby_posix_mq/NEWS.atom.xml
* Mailing list archives: http://bogomips.org/ruby-posix-mq/
Changes:
The major feature of this release is the POSIX_MQ.for_fd class
method thanks to Christopher Lord. The addition of the
POSIX_MQ#autoclose? and POSIX_MQ#autoclose= round out the new
feature set. All of the new methods are analogous to their
counterparts in the core IO class.
The mailing list is also moved to ruby-posix-mq@bogomips.org
and no longer requires subscription. Existing librelist
subscribers will need to resubscribe manually (as I have no
way of doing so automatically):
ruby-posix-mq+subscribe@bogomips.org
HTTP archives and instructions for extracting the mail archives
via git are available at:
http://bogomips.org/ruby-posix-mq/
Christopher Lord (1):
Ability to adopt file descriptors
Eric Wong (16):
for_fd: delay assigning to mq->des until after mq_getattr
test_posix_mq: rewrite test to not depend on DL or alarm
support autoclose= and autoclose?
pack rw_args struct
change mailing list to ruby-posix-mq@bogomips.org
doc: remove --sanitize-html option for pandoc
switch documentation to olddoc
LICENSE: allow all future versions of LGPLv3+
favor comparisons against zero instead of -1
pkg.mk: misc tweaks and updates
gemspec: remove rdoc_options setting
.gitignore: add placeholder
gemspec: use SPDX license abbreviation
misc doc updates
POSIX_MQ#autoclose= propagates to IO
GNUmakefile: ordering fix for building gem

This should allow faster instructions to be used in some cases.
Technically this may be less pedantically correct, but there is
enough existing code out there which does the same thing to
discourage kernel/libc developers from overloading negative
return values.
...And glibc even favors comparison against zero, too.
