[OpenSmalltalk/opensmalltalk-vm] callout from interp.c code to objc/swift code need autorelease pool (#374)
by johnmci 13 Mar '19

13 Mar '19

original issue exposed in pumpRunLoopEventSendAndSignal but perhaps the autoreleasepool wrapper should be higher up in say ioProcessEvents() what is happening is the call out is creating autorelease objects, but when do they get released. Other call out should be audited for the same issue. Some routines might not need a wrapper? -- You are receiving this because you are subscribed to this thread.

[OpenSmalltalk/opensmalltalk-vm] Bug in primitive 551 (SmallFloat64>> truncated) (#376)
by Juan Vuletich 13 Mar '19

13 Mar '19

There is a bug in an edge case in #truncated primitive in 64 bits Cog Spur (tested on Linux, both in Cuis and Squeak). It is when #truncated a Float that is slightly larger than SmallInteger maxVal. SmallInteger maxVal --> 1152921504606846975 If we take (1152921504606846975.0 predecessor), to ensure a Float that still fits in a SmallInteger, everything works fine: 1152921504606846975.0 predecessor asTrueFraction --> 1152921504606846848 1152921504606846975.0 predecessor asTrueFraction --> class SmallInteger 1152921504606846975.0 predecessor truncated --> 1152921504606846848 But taking 1152921504606846976.0: 1152921504606846976.0 asTrueFraction --> 1152921504606846976 (correct result) 1152921504606846976.0 asTrueFraction class --> LargePositiveInteger (ok. Doesn't fit in SmallInteger) 1152921504606846976.0 truncated --> -1152921504606846976 The primitive is answering SmallInteger minVal, (a negative number!) but it should fail, as the correct result doesn't fit in a SmallInteger. -- You are receiving this because you are subscribed to this thread.

Hi Folks, I just found a bug in an edge case in #truncated primitive in 64 bits Cog Spur (tested on Linux, both in Cuis and Squeak).

[CfP] DLS 2019 - 15th Dynamic Languages Symposium, co-located with SPLASH 2019
by Stefan Marr 08 Mar '19

08 Mar '19

======================================================================== Call for Papers DLS 2019 - 15th Dynamic Languages Symposium Co-located with SPLASH 2019, October 22, Athens, Greece https://conf.researchr.org/home/dls-2019 Follow us @dynlangsym ======================================================================== Dynamic Languages play a fundamental role in today’s world of software, from the perspective of research and practice. Languages such as JavaScript, R, and Python are vehicles for cutting edge research as well as building widely used products and computational tools. The 15th Dynamic Languages Symposium (DLS) at SPLASH 2019 is the premier forum for researchers and practitioners to share research and experience on all aspects on dynamic languages. DLS 2019 invites high quality papers reporting original research and experience related to the design, implementation, and applications of dynamic languages. Areas of interest are generally empirical studies, language design, implementation, and runtimes, which includes but is not limited to: - innovative language features - innovative implementation techniques - innovative applications - development environments and tools - experience reports and case studies - domain-oriented programming - late binding, dynamic composition, and run-time adaptation - reflection and meta-programming - software evolution - language symbiosis and multi-paradigm languages - dynamic optimization - interpretation, just-in-time and ahead-of-time compilation - soft/optional/gradual typing - hardware support - educational approaches and perspectives - semantics of dynamic languages - frameworks and languages for the Cloud and the IoT Submission Details ------------------ Submissions must neither be previously published nor under review at other events. DLS 2019 uses a single-blind, two-phase reviewing process. Papers are assumed to be in one of the following categories: Research Papers: describe work that advances the current state of the art Experience Papers: describe insights gained from substantive practical applications that should be of a broad interest Dynamic Pearls: describe a known idea in an appealing way to remind the community and capture a reader’s interest The program committee will evaluate each paper based on its relevance, significance, clarity, and originality. The paper category needs to be indicated during submission, and papers are judged accordingly. Papers are to be submitted electronically at https://dls19.hotcrp.com/ in PDF format. Submissions must be in the ACM SIGPLAN conference acmart format, 10 point font, and should not exceed 12 pages. Please see full details in the instructions for authors available at: https://conf.researchr.org/home/dls-2019#Instructions-for-Authors DLS 2019 will run a two-phase reviewing process to help authors make their final papers the best that they can be. Accepted papers will be published in the ACM Digital Library and will be freely available for one month, starting two weeks before the event. Important Deadlines ------------------- Abstract Submission: May 29, 2019 Paper Submission: June 5, 2019 First Phase Notification: July 3, 2019 Final Notifications: August 14, 2019 Camera Ready: August 28, 2019 All deadlines are 23:59 AoE (UTC-12h). AUTHORS TAKE NOTE: The official publication date is the date the proceedings are made available in the ACM Digital Library. This date may be up to two weeks prior to the first day of your conference. The official publication date affects the deadline for any patent filings related to published work.
