by Marcus Denker May 27, 2014

May 27, 2014

Slowly starting with Pharo4â¦ first goal is to get the same setup as Pharo3, after we can improve the infrastructureâ¦ while setting everything up we do some integrations. (40000 was the start image, 40001 a first empty cs update, 40002 a first update with the complete process. Missing: Monkey, Git commitâ¦) 40002 ----- 13258 indexOf: can be much faster... https://pharo.fogbugz.com/f/cases/13258

[bug?] SUnit shows wrong test result when Warning subclass signals on a test case method
by Masashi UMEZAWA May 27, 2014

May 27, 2014

Hi all, I wrote this simple test case, but the result is always 'yellow' even if assertions are right (.st code attached). MyHtmlParserWarningTestCase>>testParserWarning1 | warning | warning := MyHtmlParserWarning new. self assert: (warning category isNil). self assert: (warning reason isEmpty). warning signal: #malformed reason: 'no close tag'. self assert: (warning category = #malformed). self assert: (warning reason = 'no close tag'). I think it is a bug on SUnit, so I put the issue 13242 on fogbugz. https://pharo.fogbugz.com/f/cases/13242/ I confirmed it is reproduced in Pharo 3.0.image and the latest image (Pharo-40000.image). Best regards, -- [:masashi | ^umezawa]

Immutable collections and encapsulation
by Yuriy Tymchuk May 26, 2014

May 26, 2014

Hi, sorry if there was already this question, but I couldnât find it anywhere. Iâm looking in the OO-design concerns and it seams that Java guys are crazy about returning the collection that is used for state of an objects. The only acceptable option is returning it in the immutable wrapper. As far as I know, pharo does not have immutable collections (except from intervals and symbols). Are we missing something important, or there is a philosophy behind the building blocks we have now, and the design we come up while using them. Cheers. Uko

Clarifications with small lint rules
by Yuriy Tymchuk May 26, 2014

May 26, 2014

Hi guys, so Iâm experimenting with rules, and I have one simple question: how do I get a collection of items from some environment which violate some rule? i know that I can send #runOnEnvironment: to the rule itself and then it will use a checker to run the rule on the environment. But later I end up with the rule itself. I know that I can get all atomic rules from composite rule by sending #leaves, and there is #result method that returns environment. But there is no single way to get items from environment, and all accessors are environment-specific. Am I doing something wrong? Because Iâve spent half of a day to find out how to run a rule and get violations :). Cheers. Uko

[website] small changes
by Marcus Denker May 26, 2014

May 26, 2014

Hi, -> pharo-project.org now forwards to pharo.org (there is still old.pharo-project.org to access the old website) -> all subdomains (ci, bugsâ¦.) are now defined for pharo.org, too. (DNS propagation might take a while) -> added links to twitter https://twitter.com/pharoproject http://pharo.org/about http://pharo.org/news Marcus

NativeBoost and WKHTML
by Torsten Bergmann May 26, 2014

May 26, 2014

Hi, as there was no responded so far I tried to track the problem deeper and did a short test client in C/C++ to verify if I can call WKHTMLTOPDF there and generate a PDF and to compare to the Pharo/NativeBoost client. Attached is the according CPP file which works and results in a PDF with the google homepage. I also additionally implemented the callback functions in the Pharo wrapper and using the error handling I noticed that the component returns "Failed loading page http:// ..." With that info I compared the C/C++ calls to the Pharo/NativeBoost calls more deeply and found out that in C/C++ the following call for an object setting works (by returning 1): // this returns 1 in C/C++ which is OK int a = wkhtmltopdf_set_object_setting(os, "page", "http://www.google.de"); printf("object set %i",a); while in Pharo the same call fails (by returning 0): "The following call failed and returns 0 instead of 1" self setObjectSetting: 'page' to: 'http://www.google.de' in: os. I checked how I wrapped this API call again and again - it is fine from my side: setObjectSetting: aName to: value in: settings <primitive: #primitiveNativeCall module: #NativeBoostPlugin> ^NBFFICallout stdcall: #(int wkhtmltopdf_set_object_setting(wkhtmltopdf_object_settings* settings, char* aName, char* value)) module: 'wkhtmltox.dll' and I still have no idea why it fails. Especially because "wkhtmltopdf_set_object_setting" function is not different from "wkhtmltopdf_set_global_setting" which is exactly the same way wrapped, works and returns 1 in exactly the same example. I would really appreciate if someone could have a second look... To reproduce on Windows: 1. Download the 32 bit version of WKHTML from http://wkhtmltopdf.org and install it 2. Copy the "wkhtmltox.dll" to either the folder of the VM executable or the Windows directory so it can be found 3. Load the package WKHTML2PDF-Core-TorstenBergmann.7 from http://smalltalkhub.com/#!/~TorstenBergmann/WKHTML2PDF into Pharo 3.0#30848 4. Check the Transcript while evaluating: WKPDFLibrary example One can see that within this code #setObjectSetting:to:in: fails while #setGlobalSetting:to:in: works. Maybe I just do not see the obvious. Help is appreciated. Thanks in advance! bye T.

That is an interesting validation error. I don't have enough context to understand what exactly goes wrong here. It is of course a correct observation, as TraitBehavior>>users doesn't exist anymore.
