GSoC: call for ideas
by Damien Cassou Feb. 19, 2014

Feb. 19, 2014

Hi fellow Pharo hackers, ESUG, the European Smalltalk User Group, is applying for this year's Google Summer of Code. As you probably know, the Summer of Code provides the opportunity to fund students to work during the summer on Pharo. Please reply to this email (be sure to use "Reply to all") if you have ideas you would like to propose. Please include a summary of the project and links to web pages that can help prospective students to write their application. Please also include the following information: - if applicable, other dialects that you would be willing to mentor this project for - the skill level - name of the mentor(s), email addresses, and possibly any IRC network/channel/nickname where they can be found. Thanks for contributing to ESUG's Summer of Code application! -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm."

Bug in DateAndTime class
by Diego Lont Feb. 19, 2014

Feb. 19, 2014

Hi all, I probably should make an issue out of this, and follow the workflow, but I found a bug in the DateAndTime class in the method readFrom: This method comes in an infinite loop, if there is only a date specified: it tried to do aStream next while aStream peek is not a digit. And since aStream peek returns nil when the stream is at the end, this will result in an infinite loop. Here is the fixed method. Cheers, Diego readFrom: aStream "Parse and return a new DateAndTime instance from stream, as a Date, a Time and a TimeZone offset." "self readFrom: ' 2013-03-04T23:47:52.876+01:00' readStream" | offset date time | date := Date readFrom: aStream. [ aStream peek isDigit or: [ aStream atEnd ] ] whileFalse: [ aStream next ]. aStream atEnd ifTrue: [ time := Time midnight ] ifFalse: [ time := Time readFrom: aStream ]. aStream skipSeparators. offset := self readTimezoneOffsetFrom: aStream. ^ self year: date year month: date monthIndex day: date dayOfMonth hour: time hour minute: time minute second: time second nanoSecond: time nanoSecond offset: offset " '-1199-01-05T20:33:14.321-05:00' asDateAndTime ' 2002-05-16T17:20:45.1+01:01' asDateAndTime ' 2002-05-16T17:20:45.02+01:01' asDateAndTime ' 2002-05-16T17:20:45.003+01:01' asDateAndTime ' 2002-05-16T17:20:45.0004+01:01' asDateAndTime ' 2002-05-16T17:20:45.00005' asDateAndTime ' 2002-05-16T17:20:45.000006+01:01' asDateAndTime ' 2002-05-16T17:20:45.0000007+01:01' asDateAndTime ' 2002-05-16T17:20:45.00000008-01:01' asDateAndTime ' 2002-05-16T17:20:45.000000009+01:01' asDateAndTime ' 2002-05-16T17:20:45.0000000001+01:01' asDateAndTime ' 2002-05-16T17:20' asDateAndTime ' 2002-05-16T17:20:45' asDateAndTime ' 2002-05-16T17:20:45+01:57' asDateAndTime ' 2002-05-16T17:20:45-02:34' asDateAndTime ' 2002-05-16T17:20:45+00:00' asDateAndTime ' 1997-04-26T01:02:03+01:02:3' asDateAndTime "

Spec and menu shortcuts
by Martin Dias Feb. 19, 2014

Feb. 19, 2014

Hi, I'm in latest Pharo 3 and I found that in this tree the cmd+h shortcut is displayed (in the menu) but it does not work when I press the keys: TreeModel new roots: (1 to: 5); menu: [ :aMenu | aMenu addGroup: [ :group | group addItem: [ :item | item name: 'Halt'; shortcut: $h command; action: [ self halt ] ]] ]; openWithSpec. Do you see something wrong in my code? Is this a known issue? Thanks in advance, MartÃn

Connection closed while waiting for data in bootstrapped image

Feb. 19, 2014

Hi Sven, we can successfully load network packages to the bootstrapped image but when we try to test it using: ZnClient new get: 'http://zn.stfx.eu/zn/numbers.txt'. we get "ConnectionClosed: Connection closed while waiting for data" error after few seconds. Do you have some idea, what may be wrong? Probably something is not initialized well but I have no clue what. Cheers, -- Pavel
