[Pharo-project] Problem downloading packages with Monticello from Smalltalkhub because of setAcceptEncodingGzip

by Andrei Vasile Chis

Hi, Lately I started to get ConnectionClosed errors when loading packages from Smalltalkhub by using Monticello. It's very likely to just be a problem with my environment, as I'm connecting through a university server, but I got stuck debugging it. Just to see if I can download packages normally I tried two things: ZnClient new systemPolicy; url: ' http://www.smalltalkhub.com/mc/AndreiChis/AnnouncerCentricDebugger/main/ACD… '; beOneShot; get. ZnClient new systemPolicy; url: ' http://www.smalltalkhub.com/mc/AndreiChis/AnnouncerCentricDebugger/main/ACD… '; setAcceptEncodingGzip; beOneShot; get. In the first case it works perfectly. However when I add 'setAcceptEncodingGzip' every time I get: [ConnectionClosed signal: 'Connection closed while waiting for data.'] in Socket>>waitForDataFor: but if I proceed from this error I get the right content. Monticello uses "setAcceptEncodingGzip" so I get the above error. If I remove it, it works ok. I've tried this with the Pharo2.0-one-click image on Mac OS (all the compression tests pass). Doing a request using curl with "Accept-Encoding: gzip,deflate" to the same url works ok. Am I missing something obvious? Cheers, Andrei

I couldn't find any accessors in the image, but I think there's new UTC clock primitives available? - todayAtMilliSeconds: / todayAtNanoSeconds: use this cached value without doing any checks, so unless someone calls milliSecondsSinceMidnight (which does the correct checking), they will return false results regardless when clock passes over. Incorrect direct uses of julianDayNumber instvar: - #hasEqualTicks: compares julianDayNumber directly vs other instances julianDayNumber, rather than julianDayNumberUTC. - same for #< Cheers, Henry

[Pharo-project] plugins with pharo

by jannik laval

I am trying to use the CameraPlugin (coming from Scratch project). It works fine but I have some understanding problems: - when I put the plugin in the plugins directory near the VM (on a Mac OS application), my source code works. - when I put the plugin near the image it does not work. > I tried to load module, using "Smalltalk loadModule: fullNameOfMyModule". This method returns 0, but my source code does not work. With a one click image: - when I put the plugin in the plugins directory near the VM (on a Mac OS application), my source code works. - when I put the plugin near the image it works. Something is strange because the behavior is not the same between one-click and separated image. Another question is how to load external module/plugins in Pharo ?

For those involved on a daily basis, yes. Feedback from others after a major release shouldn't be seen as a source of disappointment. ;) Cheers, Henry

You're lucky, because in my own machine running GNU/Linux Ubuntu 12.04 the tests running in Pharo 2.0 either kills the VM or most of the time freezes the environment, depending on the weather...
