Epicea user experience report
by Ben Coman Feb. 27, 2017

Feb. 27, 2017

1. Created fresh Pharo image (build 60269) 2. Opened World > Tools > Epicea > All changes Points for discussion... a. How many submenu items are expected for Epicea? Can we push the current ones up so the Tools menu remains a flat menu. b. Do we need the two current menu items? "Current session" is encompassed by "All changes"? What expectations do people have of how often they'll use the former rather than the latter? c. When people move from Pharo 5 to Pharo 6 and in a panic want to "recover changes" for a crashed image, they'll be looking for that familiar feature name, not a new app name. Could the app name be left out or placed in brackets "Changes (Epicea)". btw, the interface looks really slick! nice work. 3. Opened World > System Browser. 4. Added package AAA All Changes window - no dynamic change. On <refresh>, still no change, i.e. no sessions #New All Changes window - not visible, no sessions. 5. Added class AA. All Changes window - no dynamic change. On <refresh>, shows new session with AAA & AA. 5. Added method... AA>a ^'something' Prompted for author, entered 'BenComan' All Changes window with session selected - dynamic update showing AA>>a. 6. Added package BBB. All Changes window - no dynamic update. On <refresh>, BBB still not visible in session. 7. Added class A to package AAA. All Changes window - dynamic update showing A. On <refresh>, BBB still not visible in session. 8. Added class BB to package BBB. All Changes window - dynamic update showing BBB & BB. a. Package creation event seems not handled properly, being only pushed through when a class is created in it. b. Since there is a dynamic update for class and method modifications, could the session creation also dynamically update it UI. ----------- 9. Killed the vm from command line $ ps -ef | grep pharo $ kill 29349 Restarted Pharo image 10. World > Tools > Epica > All changes. Authorship is inconsistent: * AAA and AA have blank author * AA>>a, A, BBB, B have author 'BenComan'. a. I understand this follows on from Author not being requested until the first method was defined. Did the old changes track the author of packages and classes at all? b. Since Epicea can track package and class authors, can we trigger the author prompt earlier for them? 11. Selected all previous changes AAA, AA, AA>>a, A, BBB, BB and did <Apply Changes>. Prompted for author. Entered 'DrWho' Existing All Changes window - no change New All Changes window - shows new session with all six changes. Authorship is a little inconsistent: * AAA and AA have author 'Unknown'. * AA>>a, A, BBB, B have blank author. 12. Killed the vm from command line $ ps -ef | grep pharo $ kill 30696 Restarted Pharo image 13. World > Tools > Epica > All changes. Authorship is a little inconsistent: First session * AAA and AA have blank author * AA>>a, A, BBB, B have author 'BenComan'. Second session * AAA and AA have blank author * AA>>a, A, BBB, B have author 'DrWho'. a. Epicea changes are reapplied as the current author. This seems a semantic change from Pharo 5 where changes were reapplied as their original author. Is this accidental or by design? Can we have some community discussion on this point (I don't remember seeing any)? cheers -ben P.S. I'll wait to see what arises out of discussion before creating any issues.

PharoLauncher Hanging

error "please insert disk" (windows vm)
by Nicolai Hess Jan. 15, 2017

Jan. 15, 2017

we have the following bug report 16928 <https://pharo.fogbugz.com/f/cases/16928/no-disk-in-the-drive-reply-to-World…> "no disk in the drive" reply to World | Save As (and other places) "On a clean Pharo4.0 #40618 image, on Windows 7 World Menu | Save As brings up a modal alert window, "There is no disk in the drive. Please insert a disk into drive <etc>" On my system, it does this 4 times. I'm assuming that each instance refers to one of the card-reader drives which are attached, but without a card inserted. This is a pain to deal with every single time a File Browser or World | Save As dialog is opened. Could the alerts either be - only raised when that specific drive is requested by a user action or, less preferably - given by a non-modal window, and fading away after a period" I was able to reproduce this error on squeaks and pharos window vm. (insert a usb card reader, with card, wait some time , remove only the card, every access on this drive, for example open a FileList and scroll to the drive letter). The solution I found is to call SetErrorMode( *SEM_FAILCRITICALERRORS)* I would like to propose the following change to sqwin32directory.c wrap the call to FindFirstFileW/FindNextFileW with UINT prevMode = SetErrorMode(SEM_FAILCRITICALERRORS); call FindFirstFileW/FindNextFileW SetErrorMode(prevMode); ... and call this functions in at least dir_lookup() (the other file/directory methods are save). Alternative solution, we could call the SetErrorMode function once at program start but I don't know if there are other "useful" errors message that we don't want to disable. I tested both solution, both seems to work fine. What do you think?

[Pharo-project] About ~= and ~~
by Clara Allende Nov. 26, 2016

Nov. 26, 2016

Hi guys, I'm wondering, why? ProtoObject>> ~~ anObject "Answer whether the receiver and the argument are not the same object (do not have the same object pointer)." self == anObject ifTrue: [^ false] ifFalse: [^ true] Instead of: ProtoObject>> ~~ anObject "Answer whether the receiver and the argument are not the same object (do not have the same object pointer)." ^(self == anObject) not And why? Object >> ~= anObject "Answer whether the receiver and the argument do not represent the same object." ^self = anObject == false Instead of Object>> ~= anObject "Answer whether the receiver and the argument do not represent the same object." ^(self = anObject) not. Is there any particular reason for this that I'm missing? Thanks in advance! -- "*Most good programmers do programming not because they expect to get paid or get adulation by the public, but because it is fun to program.*" Linus Torvalds

Nov. 16, 2016

Hi, maybe someone can help me out with this. Iâm working with ListModel that supports multiple selection and has autoDeselect turned off. Now Iâve tried to use #whenSelectionChanged: but it doesnât give any data, #whenMultiSelectionChanged: is not triggered at all, #whenSelectedItemChanged: works as for single selection list. Iâd be very thankful for any help. Uko

[Bloc] Hierarchy of BiEvent
by Denis Kudriashov Nov. 6, 2016

Nov. 6, 2016

Hi. I look at dev version of Bloc and have questions about events. There is duplicated hierarchy of OSEvent and BlEvent. For example for OSKeyDownEvent and OSMouseButtonPressEvent there are same events from Block: BlKeyDownEvent and BlMouseDownEvent. Bloc of course add many new events like BlDragEvent and BlDblClickEvent. But why we not manage all events equally? why we need this distinction? Also I was so much surprized about keyboard modifiers. In OS there is OSStateModifiers with smart boolean states like leftShiftPressed, leftAltPressed which are decoded from integer bits of raw SDL event. And in Bloc it is BlKeyModifiers which are created from OSStateModifier. And here is most amazing thing: BlKeyModifiers encode smart boolean flags about keys back into integer bits. So we have: SDL event int => OSStateModifiers booleans => BlKeyModifiers int Why it is done like this? And currently BlKeyModifiers lost many states from OSStateModifiers.

Re: [Pharo-dev] [Seaside-dev] Build failures
by Sven Van Caekenberghe Nov. 3, 2016

Nov. 3, 2016

It already got reported twice, there are issues for it, but so far no luck (i.e. no actual resolution). I would guess that before the linux os of the CI slaves ran in 32-bit, while now it got upgraded to 64-bit.

Mocks are missing in Pharo (from thread OSProcess is missing)
by Denis Kudriashov Nov. 2, 2016

Nov. 2, 2016

We always said that smalltalk is the best for TDD. But we not have mocks by default in Pharo while mocks is fundamental part of TDD. So no kernel tests could benefit from them. And more important TDD is design process and without mocks we can't apply it to kernel with full power. What you think to integrate Mocketry in Pharo 6? It has comments and documentation (PharoInProgress, Help), advanced features and it is very competitive to any modern mock libraries. Best regards, Denis
