Most notably there's a new RB_GC_GUARD to fix an occasional segfault at
load time for Ruby 1.8 users thanks to Petr Novodvorskiy for reporting
the issue.
There's been a new mailing list for a few months now at:
kgio-public@bogomips.org
No subscription is required, but if you wish to subscribe
(existing librelist subscribers must resubscribe)

There's also a bunch of code cleanups and packaging
cleanups. Our website is faster now thanks to olddoc:

No longer needed for olddoc

We'll get EXTCONF_ARGS support as well as a muscle-memory-friendly
"make check" alias.

Define a MY_ARY_SUBSEQ macro which checks arg counts correctly and
avoids throwing off people who may potentially want to debug this
code.

Define a MY_STR_SUBSEQ macro which checks arg counts correctly and

These are emitted by clang on a Ubuntu Trusty amd64 system.

We don't need references to RubyForge or old images crap.

The FSF has and may move again physically, so the URL should be
more future-proof.

Calling rb_intern(RSTRING_PTR(err)) was unsafe as the `err'
value could be GC-ed inside rb_intern.
This only affected Ruby 1.8 as Errno.constants returns an
array of Symbols under 1.9+
Thanks to Petr Novodvorskiy for reporting the issue.

The future of this project is to have no future.

wrongdoc was difficult to maintain because of the tidy-ffi
dependency and the HTML5 changes in Darkfish could not be
handled well by Tidy.
olddoc is superior as it generates leaner HTML which loads faster,
requires less scrolling and less processing power to render.
Aesthetic comparisons are subjective of course but completely
unimportant compared to speed and accessibility.
|
|
License field is commonly supported nowadays, and Rubyforge is dead.
Note: wrongdoc will be replaced with something more old-fashioned :)
|
|
In case I'm hit by a bus, the lesser evil is to allow the FSF
to update our license than to be stuck as LGPLv3-only in the
future.

You may (optionally) subscribe to the new mailing list at:
kgio-public+subscribe@bogomips.org
If your ISP prevents you from using port 25, port 587 (submission) is
open on bogomips.org. You may use Tor if you do not wish to expose your
IP when using port 587.
Any HTML mail will be flagged as spam, so please do not send it and
waste storage and bandwidth on it. Basic, old-fashioned mailing list
conventions apply: no top-posting, trim replies, attribute your quotes,
short signatures, etc.
This existing list will operate in public-inbox "hijack mode":
the new address is subscribed to the old librelist, so any messages
sent to the librelist are automatically archived to the new
public-inbox. Of course, not much happens here, anyways, so
nobody notices :)
Background:
Over the years, I've come to disagree with the subscription-required
posting policy of librelist. Combined with disabling of rsync archives,
one of my main reasons for choosing librelist back in the day are gone.
Lately, I've also been working on public-inbox, http://public-inbox.org/
an "archives-first" approach to mailing lists using git.
ssoma (git) archives are available at: git://bogomips.org/kgio-public/
The ssoma format is described at http://ssoma.public-inbox.org/
HTML archives are going to http://bogomips.org/kgio-public/
All archives imported from gmane, and posts to this librelist
also go there.

penultimate return value may be a subarray for writev-related

This release is for compatibility with future releases of mainline ruby,
as rb_thread_blocking_region is removed in r44955 of ruby trunk
This also avoids deprecation warnings fo rb_thread_blocking_region
2.0 and 2.1.
|
|
We've finally figured out how to avoid warnings when building on
C Ruby 2.x
|
|
It'll be OK to use rb_thread_call_without_gvl when
rb_thread_blocking_region is not detectable at all.
We still use rb_thread_blocking_region for Ruby 2.0-2.1 because
rb_thread_call_without_gvl was detectable in 1.9.3, but not
usable as an internal symbol.

Thanks to Christopher Rigor for this release.
Eric Wong (2):
only define and test kgio_syssend on 1.9+
various 1.8.7 fixes

Some errors in the code reorganization caused some compatibility
code to be dropped :x

This adds a new kgio_syssend method for Ruby 1.9+ which behaves
like BasicSocket#send, but will not raise exceptions on EAGAIN.
Eric Wong (12):
test_poll: remove race prone test_poll_EINTR_changed test
tryopen: remove RARRAY_PTR usage in init
read_write: remove the rest of RARRAY_PTR usage
my_writev: stylistic fixes
Rakefile: kill raa_update task
avoid downsizing casts
connect: constify RSTRING-related things
set RSTRING_MODIFIED where appropriate for Rubinius
split read_write.c into {read,write,writev}.c
add kgio_syssend method to wrap send(2)
write: correct check for various blocking regions
tryopen: additional debug information for bad Errno values
Hleb Valoshka (1):
Don't use deprecated api

In case users run into the same problem in the future.

This will allow us to support past/future Rubies without
rb_thread_io_blocking_region but still have other ways
of releasing GVL.
|
|
This behaves like kgio_trywrite on GNU/Linux, but allows extra flags
to be specified. The main purpose of this is to support use of the
MSG_MORE flag on GNU/Linux.
|
|
This helps make our code more manageable, as well as isolating
RSTRING_MODIFIED usage to files which actually need it.
writev.c can eventually be fixed to avoid modifying RSTRING
pointers, but write.c can already benefit from const RSTRING_PTR
values right away.
|
|
Not yet tested, but it makes sense to do this.
|
|
This should enforce correctness with our non-use of RSTRING_MODIFIED
in this file, hopefully allowing Rubinius to optimize better.
|
|
It's always safe to cast a 32-bit value to a 64-bit value, but
compilers can warn going the other way (because VALUE is a pointer).
Tested with `ruby -v`
ruby 2.2.0dev (2014-01-19 trunk 44646) [x86_64-linux]
which enables -Wpointer-to-int-cast

RAA is dead
|
|
Rename 'str' to 'ary', as that's the whole point of supporting
writev... Also, long lines need to be wrapped at 80 columns
|
|
I have not benchmarked this, but this should not make a difference
as far as performance goes. This should also allow better
performance of better GCs in Ruby 2.1.0 and Rubinius.
|
|
This is trivially non-performance-critical, and can only
help with advanced GCs in Ruby 2.1.0 and Rubinius
|
|
We haven't figured out a way to reliably test this w/o races, so lets
just remove it for now and trust it works by reading the C code.

Improved error reporting for kgio_accept/kgio_tryaccept.
Minor size reduction throughout. There are also several
test case fixes for race conditions.
Thanks to Hleb Valoshka and the Debian project for all the
help with this release!
Eric Wong (7):
check syscall returns against < 0 instead of == -1
accept: more informative exception on unknown family
test_tryopen: skip EACCES test when euid == 0
test/lib_read_write: account for larger-than-normal pipes
test_poll: avoid potentially thread-unsafe test
test_poll: preserve original trap(:USR1) handler
test_poll: be less dependent on signal handler ordering
Hleb Valoshka (4):
Change prefix of temporary sockets to prevent races
Don't dump 20M in case of failure
Create own directory for every unix socket in unit tests
Close tempfile and unlink it immediately.
|
|
When a Tempfile object is garbage collected, or when the Ruby interpreter
exits, its associated temporary file is automatically deleted. This may
lead to race condition when Tempfile is used like in these tests.

Just spam the thread several times to force the wakeup to happen
and not be as dependent on signal handler execution ordering of
different Ruby VMs.

[ew: this avoids a TOCTOU issue for multiple test invocations]
Signed-off-by: Eric Wong <normalperson@yhbt.net>
|
|
The existing SIGUSR1 handler may not always be "DEFAULT",
so restore the original one.
|
|
Modifying pollset in a different pollset is thread-unsafe,
so just do that inside the signal handler as that should
fire before restarting poll().
|
|
Linux pipe buffers may use larger pages and increase the
capacity of pipes. Thus the 10000 write attempt is not
sufficient; just infinite loop until we hit :wait_writable.
|
|
This fails when the test is run as root (which may be the case
of some Ruby installations) or fakeroot (which is the case of
Debian build systems).

Note: this is an incomplete fix and the race can still happen.
A proper fix would involve using a temporary directory for each
test and placing the Unix socket in there.

This may help us diagnose issues on strange OSes.

This may help us avoid errors in case of C library bugs,
and also results in smaller code:

TCP Fast Open in Linux 3.7 and later is now supported
in the client via Kgio::Socket#kgio_fastopen.
This release also adds the kgio_writev and
kgio_trywritev methods, thanks to funny-falcon
