Analysis of CI issues and call to action

by Max Leske

Hi Iâve been poking at the issue validator to figure out why itâs behaving so funny. Iâve run these tests locally and either the first part of the validation runs fine and the validation proceeds to run the tests or it fails after about one minute due to a timeout (which isnât actually one, see below). I found two things which may or may not be related: 1. Many times (but not always) the forked images signal the scheduled delays upon startup. 2. Some of the forked images do not (always) get a new session (itâs like the startup code doesnât even runâ¦ so weird). AFAICT, both always occur together. The main effect of this is that timeout blocks get evaluated when thereâs really no timeout (the timeout is set to 100 minutes for rules and 20 minutes for forked images). A timeout is treated as a validation error which is reflected in the output: Validation Errors: a CISUnitTestsRule: Timeout (after 0:01:40:00) occured while loading "Can not create a subclass of TestCaseâ A different effect is that the image worker can not distinguish the forked image from the parent image since the session hasnât changed. This can (potentially) lead to the parent image waiting for the forked image which is waiting for itself (thinking it is the parent image) and the whole thing will be hung up. Note that âforkedâ in this context actually means an image that is a copy, saved with #backupAs: and run with OSProcess (see ImageWorker). I think both issues need to be investigated urgently. They are not only a problem for the CI but have implications for every user. I have opened two sub cases of https://pharo.fogbugz.com/f/cases/17778/Monkey-now-fails-all-the-time to track both these issues: https://pharo.fogbugz.com/f/cases/17814/Delays-in-forked-images-get-signale… https://pharo.fogbugz.com/f/cases/17815/Session-isn-t-always-updated-correc… Please, if you have a little spare time (and a lot of patience) help us to get rid of these issues. To run the code locally you can use the tracker image (with some extra logging and missing information filled in by me) found here: https://www.dropbox.com/s/7b6hbsb8gjxagxc/tracker_image.zip?dl=0 or get your own fresh copy from here: https://ci.inria.fr/pharo/view/5.0-Analysis/job/Pharo-5.0-Issue-Tracker-Ima…. Then run it from the console like so: ./pharo ~/Downloads/Pharo-5/Pharo-5.0-Issue-Tracker-Image.image ci slice --issue=17809 Iâve tested this with CoInterpreter VMMaker.oscog-eem.1722 uuid: e5c44d63-ba75-4cd1-bf4e-c92c4232bbfe Mar 11 2016 StackToRegisterMappingCogit VMMaker.oscog-eem.1722 uuid: e5c44d63-ba75-4cd1-bf4e-c92c4232bbfe Mar 11 2016 https://github.com/pharo-project/pharo-vm.git Commit: ded69213d3b73ffbda27417c19cb75fd6b325c82 Date: 2016-03-11 17:48:52 +0100 By: Esteban Lorenzano <estebanlm(a)gmail.com> Jenkins build #572 on OS X 10.11.3 (El Capitan).

Ah, I don't know but there are issues in the package in SS3 (e.g. Matrix extension not using the right instVar names). I am using a 4.0 here, 5.0 seems to have too many issues at this point. FWIW I'll be doing a new project using Pharo so, 4.x is the stable ground for me. I am also busy with TWM for 5.x but experiencing UI lockups due to some changes linked to how events are handled etc. Phil On Sun, Mar 13, 2016 at 4:11 PM, Sven Van Caekenberghe <sven(a)stfx.eu> wrote: > But at least the simple ones are already in the image, no ? > > #(1 2 3) * 2 => "#(2 4 6)" > #(1 2 3) * #(4 5 6) => "#(4 10 18)" > > > On 13 Mar 2016, at 16:06, phil(a)highoctane.be wrote: > > > > There are extensions to have e.g. #* or #+ ... applied to a collection > (or Matrix). > > > > Works for aCollection * aNumber or aCollection * aCollection > > > > (some of these are using quadratic time to do where there are algorithms > to do that with less time). > > > > Phil > > > > > > On Sun, Mar 13, 2016 at 1:50 PM, Werner Kassens <wkassens(a)libello.com> > wrote: > > look in squeaksource projects for 'Collections Arithmetic extensions' > > werner > > > > On 03/13/2016 01:36 PM, stepharo wrote: > > Collections extension to treat vectors of number > > But I cannot find it anymore :) > > > > > > Le 13/3/16 13:30, Sven Van Caekenberghe a Ã©crit : > > this link does not point to anything for me. > > what are we talking about ? > > > > On 13 Mar 2016, at 12:36, phil(a)highoctane.be wrote: > > > > I like to use these. > > > > http://www.squeaksource.com/@G_BxD77Hzwe-SmwI/hUjIUazY > > > > Now there aren't in PharoExtras. > > > > Shouldn't we have that there? > > > > Phil > > > > > > > > > > > > > > > > >

There are extensions to have e.g. #* or #+ ... applied to a collection (or Matrix). Works for aCollection * aNumber or aCollection * aCollection (some of these are using quadratic time to do where there are algorithms to do that with less time).

Probably a different one. In the mid time I got again the same freeze. So it is more frequent than I thought. stef Le 13/3/16 13:52, Thomas Heniart a Ã©crit : > I have a strange bug too with a fresh image just downloaded > > When I create a new method in a class, the shortcut to create a block > expression (alt + shift + 5) does not work
