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.

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?

IDNA / punycode for Zinc?
by Max Leske Dec. 28, 2016

Dec. 28, 2016

Hi (Sven), Zinc canât currently handle unicode domain names (e.g. http://Ã¼ni.ch <http://xn--ni-wka.ch/>). Are there any plans to implement punycode / IDNA conversion for Zinc? Or is there an explicit reason not to support it? I see that #parseHostPort: expects the host portion to be percent escaped, what is the use case for this? I have never seen a percent escaped host portion. Usually the host portion is either pure ASCII, unicode or punycode (in my experience at least). Just curious, as I just added IDNA conversion to one of our applications (I just let python perform the conversion: https://docs.python.org/2/library/codecs.html#module-encodings.idna <https://docs.python.org/2/library/codecs.html#module-encodings.idna>). Cheers, Max

How to report website text bugs?
by Tim Mackinnon Dec. 7, 2016

Dec. 7, 2016

Hi Guys - how is the best way to report website and text bugs? As I know the English is not always a first language (and you guys are busy writing code anyway) - its up to us native English speakers to chip in where we can. I was pleased to get the notice that on OSX Sierra I need to do something extra to get Pharo to work, however the text could be slightly corrected eg. (Bolded words changed) Are you using macOS Sierra? Due to changes in security policies of macOS, you will need to put the VM in the /Applications folder. We are working to fix this temporary inconvenience. Also - the Hello world command line example on the front page doesnât work on a standard Terminal on a Mac (you get an error: $ ./pharo Pharo.image eval "Stdio stdout << 'Hello,World!'" -bash: !'": event not found The culprit is of course the â!â Character so a better example might be: $ ./pharo Pharo.image eval "Stdio stdout << 'Hello World'" Hello WorldStdioStream: 'stdout' Although, in this case, is it expected that the return string is merged with some other output text (e.g. the StdioStream:â¦.?). I think its an impressive example, but it just doesnât quite look right? Tim

Seaside / Getting Started
by Nicolai Hess Dec. 4, 2016

Dec. 4, 2016

Hi, I am currently reviewing the Seaside chapter of "Pharo By Example 5". The chapter is about Seaside 3.1 ( http://files.pharo.org/seaside/Seaside-3.1-portable.zip) But some parts the book refers to has changed, and I am asking here to see whether my changes/updates will be correct, and for some changes I don't know what to change. 1. configure seaside: open http://localhost:8080/seaside/config *I* think the following description expects this (old 2.8?) version output: (seaside_284_config.PNG) but instead, we get: (seaside_31_config.PNG) 2. And in the current (3.1) version, there is now login/password request. I will remove this from the description, but does anyone know how we would enable a login/password request for the config page? 3. Now, there is a step-by-step description how to add a copy of the example "counter" as "counter2", but the config page doesn't look like the description in any way. I guess the right description would be: change to the "examples folder" on the right, add push the "Add" buttton on the top pane (seaside_31_examples.PNG) instead of "Add entry point" (can not find this in any config page), we need to push the Add button and choose the dispatcher type: (seaside_31_examples_add.PNG) finally we need to set the root class ... Is this correct ? Is there already a updated documentation that describes this (adding a counter-example) with the newer interface? Thanks in advance nicolai (more questions will follow)
