Bug 1134: Add getentropy interface OPEN
http://austingroupbugs.net/view.php?id=1134
Action: Andrew to add boilerplate response regarding a proposal for
new interface, and also to ask The Open Group OR if they would
sponsor this addition.
Both Actions now Completed.

There has been no reaction from the Base Working Group and the period for
comments has ended now.
Bug 1138: Add strsignal(), sig2str() and str2sig() to the standard. OPEN
http://austingroupbugs.net/view.php?id=1138
Martin has completed his action. Andrew took an action to chase
the Base Working group members for sponsorship of the two interfaces.
Update: The action on Andrew is still open.
Bug 1141: Add WCOREDUMP(stat) to sys/wait.h Accepted as Marked
http://austingroupbugs.net/view.php?id=1141
A comment was received by email during the week.
The following change was made to the changes to be made in bugnote:4157.
On page 409 line 13896 section <sys/wait.h>, add before WEXITSTATUS:
<blockquote>WCOREDUMP True if WIFSIGNALED is true and creation of a core image
was attempted.
NOTE: The use of the word "attempted"
here means that the process terminated abnormally
with actions (see "SIG_DFL" in [xref to 2.4.3 Signal Actions]).
A core image might or might not have been
produced. Some implementations do not set this bit if
a core image was not produced, but this is not a requirement.
</blockquote>
The bug is still resolved with Accepted as Marked and Issue8 tag.
Bug 0001143: cancellation points: contradiction between base definition and
rationale Accepted as Marked
http://austingroupbugs.net/view.php?id=1143
An interpretation is required
The item is tagged for TC3-2008
Interpretation response:
The standard states the requirements for thread cancellation when
a timeout occurs, and conforming implementations must conform to
this. However, concerns have been raised about this which are being
referred to the sponsor.
Rationale:
The change made as a result of ERN 207 in
https://www.opengroup.org/austin/aardvark/latest/xshbug2.txt [^]
was intended simply as a clarification as to whether a timeout
counts as part of "the event for which it is waiting". However, the
change that was made was not quite right, as the "if the thread is
suspended at a cancellation point" condition should have applied
to the timeout case as well.
The point of this part of the standard is that once a function that
is a cancellation point has become suspended, then a cancellation
request interrupts the suspension and terminates the thread. The
function does not perform any further processing as it does not
return from suspension, and thus it can assume that once it suspends,
cancellation is taken care of and it doesn't need to do any further
checking for cancellation. If a cancellation request is made
simultaneously with another event that would end the suspension,
there is a race and it is unspecified who wins.
Notes to the Editor (not part of this interpretation):
Change:
It is unspecified whether the cancellation request is acted
upon or whether the cancellation request remains pending and
the thread resumes normal execution if:
* The thread is suspended at a cancellation point and the
event for which it is waiting occurs
* A specified timeout expired
before the cancellation request is acted upon.
to:
It is unspecified whether the cancellation request is acted
upon or whether the cancellation request remains pending and
the thread resumes normal execution if the thread is suspended
at a cancellation point and either:
* The event for which it is waiting occurs
* A specified timeout expires
before the cancellation request is acted upon.
Bug 1144: May fmemopen(buf, len, "r") modify the buffer OPEN
