Autoscrolling (in FastTable)
by Stephan Eggermont Nov. 29, 2015

Nov. 29, 2015

Today we've had a design discussion on slack on autoscrolling with Morphic. The idea is to start scrolling up or down when drag-holding over a table. A similar approach should hold for scrolling panes. It started with me describing a working but not so nice approach starting stepping on #mouseEnterDragging:, checking the global hand position and button state in each #step:, stopping the stepping on #mouseLeaveDragging: or #mouseUp:. Thierry noticed the #newMouseFocus: taking of FastTable on #mouseEnterDragging: causes problems when dragging from one table to itself without leaving the table bounds. Henrik then wrote the code for FastTable, removing the mouse focus taking by adapting #handleMouseMove: The first results are in the latest version of FastTable on estebanlm/FastTable. The top and bottom parts of the table will now start scrolling the table rows when drag-holding over them. Further possible improvements: - expand/contract tree triangles when holding over them, taking priority over the start of autoscrolling; - adapt scrolling speed depending on distance from border - check starting delay, repeat rate and smoothness of the scrolling Stephan

[Pharo5] Semantic Warnings as icons in the editor
by Marcus Denker Nov. 29, 2015

Nov. 29, 2015

Hi, One result of Fridayâs Pharo Sprint in Chile: Use the nice icons of the new text editor to display some of the semantic errors nicely (instead of breaking flow with a intrusive dialog): This was done by Johan based on the prototype Miguel did in September: 1) unused temps: (the âdrag the crosshairâr is an artefact of the snapshot tool) 2) temps used that are not initialised: In a next step, we need to integrate that with the QA toolâ¦ no need to have this reported twice. What is nice is that this simplified the Compiler: instead of having an Exception and raising it, we now just annotate the AST: unusedVariable: variableNode variableNode propertyAt: #semanticWarning put: 'unused variableâ (this is very simple for now, with a node just being able to have one kind of semanticWarning). SemanticWarningIconStyler is what adds the icon. It has 4 methods with one line each. Marcus

Delay>>waitOtherwise:
by Ben Coman Nov. 28, 2015

Nov. 28, 2015

I think I made a mistake introducing Delay>>waitOtherwise: to be used by World>>interCyclePause: . Its requirement that #schedule: return a boolean complicates all those methods. In review now, I was being too conservative while letting the refactored delay scheduler code settle in. Would anyone mind if I revert that? cheers -ben

Occasional random validation failures
by Ben Coman Nov. 28, 2015

Nov. 28, 2015

In case 16962 [1] the question was raised why after a successful CI validation you later get a failed validation. I experience this sometimes and guess others might interested in this too. If multi-threads are involved, sometimes the failure indicates a real problem due to a race condition that only occurs sometimes. Here you will see lots of tests passing and then a problem on a particular one. In this case I find running the suspect test or class from playground wrapped in a 1000 loop can expose the problem for debugging. In the case of 16962 [1], looking at a report for success [2] you can see "CIChangeCaseValidationRule" is followed by "Loading CASE 16962" and then a long listing of tests run, and only at the end the validation report. However the report for failure [3] shows CIChangeCaseValidationRule immediately followed by the validation report. So I wonder if that means the slice did not load - maybe due to some network error or smalltalkhub error. Now thats idle speculation, but maybe useful to consider if you encounter such a scenario. cheers -ben 2015-11-28 3:56 AM SUCCESS [2] [...] Starting validation of CASE 16962 http://smalltalkhub.com/mc/Pharo/Pharo50Inbox/main/SLICE-Issue-16962-Code-p… Notice: Running a CIAndRule Notice: Running a CIChangeCaseValidationRule Notice: Loading CASE 16962 http://smalltalkhub.com/mc/Pharo/Pharo50Inbox/main/SLICE-Issue-16962-Code-p… [...cut many,many lines of test cases...] ========================================================== Validation Report: CASE 16962 http://smalltalkhub.com/mc/Pharo/Pharo50Inbox/main/SLICE-Issue-16962-Code-p… ========================================================== Validation Success: CASE 16962 http://smalltalkhub.com/mc/Pharo/Pharo50Inbox/main/SLICE-Issue-16962-Code-p… [...] 2015-11-26 10:29 PM FAILURE [3] [...] Starting validation of CASE 16962 http://smalltalkhub.com/mc/Pharo/Pharo50Inbox/main/SLICE-Issue-16962-Code-p… Notice: Running a CIAndRule Notice: Running a CIChangeCaseValidationRule ========================================================== Validation Report: CASE 16962 http://smalltalkhub.com/mc/Pharo/Pharo50Inbox/main/SLICE-Issue-16962-Code-p… ========================================================== Validation Errors: a CIChangeCaseValidationRule: Timeout (after 0:01:40:00) [...] [1] https://pharo.fogbugz.com/default.asp?16962 [2] https://ci.inria.fr/pharo/job/Pharo-5.0-Issue-Validator/20704//artifact/val… [3] https://ci.inria.fr/pharo/job/Pharo-5.0-Issue-Validator/20587//artifact/val…

Improving API of Date, Month....
by stepharo Nov. 28, 2015

Nov. 28, 2015

Hi I was reading the code of Date and I was expecting to get some methods such as monthNames dayNames daysInMonths Ok they are stored in ChronologyConstants but they are not accessible. There is no monthNames nor Do I imply something strange or silly? I think that it would make sense to add them. Stef

Bug with latest image of Pharo 5
by Dimitris Chloupis Nov. 27, 2015

Nov. 27, 2015

Using latest VM on macos Yosemite Are you guys aware of this bug ? [image: Screen Shot 2015-11-27 at 12.19.22.png] This bug strangely happens only for classes with very large amount of methods like the morph class when viewing all protocol and it does not happen immediately, it takes some time to happen and several clicks and navigations through methods. For small classes it does not happen. I am having this bug for several weeks now with several latest images of Pharo 5. Is anyone else experiencing this ?

Debugging a failing test doesn't include the full stack
by Esteban A. Maringolo Nov. 27, 2015

Nov. 27, 2015

I'm trying to debug a failing test case in Pharo 5, but for some reason in certain tests I can't see the full stack, so basically I can't fix nor diagnose the failing test within the debugger because I only get the assert notification. This doesn't happen in Pharo 4, there seems to be a refactoring of the TestCase hierarchy, but I don't know how it affects the exception handling, which in the case of Glorp seems to not be very orthodox. Regards! â Esteban A. Maringolo
