Re: [Vm-dev] OSProcess fork issue with Debian built VM
by Max Leske 03 Aug '17

03 Aug '17

We managed to figure out that OSProcess works when we use gcc <= 4.8 on Debian. We are happy to use 4.8 for now, so we're good. It would of course be super cool if we could use the series 6 gcc as that will soon ship with Debian 9 (stretch) but it's probably not trivial to just move to a new compiler version (as seems evident from the fact that a minor version change can mess up compilation). Thanks for your help Alistair and Eliot.

the purpose of CI
by Ben Coman 08 Jun '17

08 Jun '17

Maybe I'm speaking out of turn from the sidelines, but just curious to ask a leading question... What is the purpose of the Continuous Integration system? I notice Travis has not had a green build for nearly 120 days https://travis-ci.org/OpenSmalltalk/opensmalltalk-vm/builds since Build #603... https://travis-ci.org/OpenSmalltalk/opensmalltalk-vm/builds/200671152 I'd guess that makes it harder to identify which "new" commits introduce "new" defects. It was tough for me trying to categorise the historical failures to understand what might be required to make them green. For example, lately the usual failure has been just a single job... macos32x64 squeak.sista.spur. which last worked 22 days ago in Build #713 https://travis-ci.org/OpenSmalltalk/opensmalltalk-vm/builds/228902233 but there are other failures in builds that obscure that fact, way back to #603. Only an exhaustive search through all builds reveals this. For example, recent Build #748 has macos32x64 squeak.sista.spur as its only failure https://travis-ci.org/OpenSmalltalk/opensmalltalk-vm/builds/236010112 but then #750,#751, #752, #753 introduce other failures. Perhaps a contributing factor is commits being pushed directly to the server Cog branch, with CI tests only running after they are integrated. I guess that was done to keep the workflow similar for those moving from subversion to git. However it seems to lose some value of CI in "preventing" build failures from entering the repository. After a year of using git maybe this workflow could be reconsidered? Perhaps turn turn on branch protection for administrators and "force" all commits to the server Cog branch to first pass CI testing? Of course needing to submit everything via PRs adds workflow overhead, but some workflows might minimise the impact. So I can't argue whether the benefit is worth it, since I'm not working in the VM every day. I'm just bumping the status quo to table the question for discussion. cheers -ben P.S. Should macos32x64 squeak.sista.spur be fixed, or temporarily removed from the build matrix? A continually failing build seems to serve no purpose, whereas green builds should be a great help to noticing new failures.

VM Maker: VMMaker.oscog-eem.2222.mcz
by commits＠source.squeak.org 05 Jun '17

05 Jun '17

Eliot Miranda uploaded a new version of VMMaker to project VM Maker: http://source.squeak.org/VMMaker/VMMaker.oscog-eem.2222.mcz ==================== Summary ==================== Name: VMMaker.oscog-eem.2222 Author: eem Time: 26 May 2017, 3:24:23.911304 pm UUID: 72a78cd4-0916-4b02-afea-75e4ee736bac Ancestors: VMMaker.oscog-nice.2221 StackInterpreter: Add time primitives to answer the UTC and local microsecond clocks as updated by the heartbeat (as the Cog VM was originally before David changed the primtiives to access the time now). This access is much faster (of the order of 20 nsecs per invocartion vs 450 nsecs per invocatuon on a 2.3 GHz Mac Mini). Terf demands very fast clock times but is not concerned with fine granularity. The primitive numbers are 245 for UTC and 246 for local. primitiveMakePoint should fail if its /argument/ is not a SmallInteger or Float. Since the primitive is on Number we know the receiver is valid, and there is no point chekcing it. Checking the argument allows us to e.g. make 3D point using a cascade of @'s. Fix warnings for addIdleUsecs: on WIN32/64 (must not be marked exporrt to avoid declspec being added). reverseDisplayFrom:to: slightly improved if it does the addition at start of loop, not on every iteration. Cogit: primitiveCollectCogCodeConstituents should verify its argument (if it has one) and fail if not given a boolean. If it is given an argument it must remove it from the stack.

OSProcess fork issue with Debian built VM
by Max Leske 04 Jun '17

04 Jun '17

Hi, We're building the pharo.cog.spur VM on Debian (32 bits, itimer, on 64 with compat libs). Unfortunately, we're running into one particular problem with OSProcess. Some primitives like primitiveFileStat work but forking a child process (e.g. with #waitForCommand) produces a segfault. We've tried to find a difference between our build and the VM downloaded from bintray but we weren't very successful. One difference we do see is that our libc6 version is 2.19, while the one used in the travis build is 2.15 (although both binaries use the 2.19 version at runtime). I'm aware that OSProcess hasn't been tagged as officially ready for Pharo 6 (which is where I'm using it). However, all of my tests with the prebuilt VM's have been successful. Do any of you have an idea as to what the problem could be? I've attached the stack trace below. One possibly interesting thing is that the stack trace is being printed in an infinite loop, i.e. the process isn't killed but the VM just keeps printing out the same trace. Cheers, Max could not open "[redacted]/crash.dmp" for writing.
