[Pharo-project] Gettext in Pharo2.0
by Johan Brichau April 3, 2013

April 3, 2013

Hi, Loading Gettext into Pharo2.0 crashes badly (system locks up, eventually an emergency debugger appears). The reason is the class initialization of NaturalLanguageTranslator: Smalltalk addToStartUpList: NaturalLanguageTranslator after: FileDirectory. Because the class FileDirectory is no longer in that list, it crashes. So, my questions: - should it not produce a nicer debugger window? - I can fix the load problem itself and also take a look to port this package to Pharo2.0 if it requires more than adapting the above. But I have no write access to the PharoNonCorePackages repository. Is there a new location? Or is there already a version for Pharo2.0 somewhere? Or should we move it out of that repository and give it it's own special place? cheers Johan

[Pharo-project] NativeBoost problems on Linux
by Jimmie Houchin April 3, 2013

April 3, 2013

Hello, I am having problems with code interfacing a C library on Ubuntu 12.10 32bit. I loaded my code into a clean Pharo 2.0 install. My code works perfectly when run on Windows 7. The Linux libraries work perfectly when running the demo C apps which come with the library. "I create the object." s := FXSession new. "I attempt to login" s login: ( FXSession demoArgs ). "If login is successful, I test with getServerTime." s getServerTime. Creating the object is successful. The login seems to freeze the UI. Then after a number of minutes. I don't know how many. I didn't watch. I then get the below output in the terminal. jimmie@squirrel:~/Dev/Pharo/pharo2.0$ ./pharo shared/Pharo2.0.image ALL=0;ERR=0;LAST=0;ARML=0ALL=0;ERR=0;LAST=0;ARML=0ALL=1;ERR=1;LAST=0;ARML=0ALL=1;ERR=1;LAST=0;ARML=0^C jimmie@squirrel:~/Dev/Pharo/pharo2.0$ ./pharo shared/Pharo2.0.image ALL=0;ERR=0;LAST=0;ARML=0ALL=0;ERR=0;LAST=0;ARML=0ALL=1;ERR=1;LAST=0;ARML=0ALL=1;ERR=1;LAST=0;ARML=0ALL=2;ERR=2;LAST=0;ARML=0ALL=2;ERR=2;LAST=0;ARML=0ALL=3;ERR=3;LAST=0;ARML=0ALL=3;ERR=3;LAST=0;ARML=0ALL=4;ERR=4;LAST=0;ARML=0ALL=4;ERR=4;LAST=0;ARML=0ALL=5;ERR=5;LAST=0;ARML=0ALL=5;ERR=5;LAST=0;ARML=0ALL=6;ERR=6;LAST=0;ARML=0ALL=6;ERR=6;LAST=0;ARML=0ALL=7;ERR=7;LAST=0;ARML=0ALL=7;ERR=7;LAST=0;ARML=0ALL=8;ERR=8;LAST=0;ARML=0ALL=0;ERR=0;LAST=0;ARML=0ALL=1;ERR=1;LAST=0;ARML=0ALL=2;ERR=2;LAST=0;ARML=0ALL=3;ERR=3;LAST=0;ARML=0ALL=4;ERR=4;LAST=0;ARML=0ALL=5;ERR=5;LAST=0;ARML=0ALL=6;ERR=6;LAST=0;ARML=0ALL=7;ERR=7;LAST=0;ARML=0ALL=8;ERR=8;LAST=0;ARML=0ALL=9;ERR=9;LAST=0;ARML=0ALL=10;ERR=10;LAST=0;ARML=0ALL=11;ERR=11;LAST=0;ARML=0ALL=12;ERR=12;LAST=0;ARML=0ALL=13;ERR=13;LAST=0;ARML=0ALL=14;ERR=14;LAST=0;ARML=0ALL=15;ERR=15;LAST=0;ARML=0ALL=16;ERR=16;LAST=0;ARML=0ALL=17;ERR=17;LAST=0;ARML=0ALL=18;ERR=18;LAST=0;ARML=0ALL=19;ERR=19;LAST=0;ARML=0ALL=20;ERR=20;LAST=0;ARML=0ALL=21;ERR=21;LAST=0;ARML=0ALL=22;ERR=22;LAST=0;ARML=0ALL=23;ERR=23;LAST=0;ARML=0ALL=24;ERR=24;LAST=0;ARML=0ALL=25;ERR=25;LAST=0;ARML=0ALL=26;ERR=26;LAST=0;ARML=0ALL=27;ERR=27;LAST=0;ARML=0ALL=28;ERR=28;LAST=0;ARML=0ALL=29;ERR=29;LAST=0;ARML=0ALL=30;ERR=30;LAST=0;ARML=0 Segmentation fault Tue Apr 2 21:10:46 2013 pharo VM version: 3.9-7 #1 Wed Mar 13 18:22:44 CET 2013 gcc 4.4.3 Built from: NBCoInterpreter NativeBoost-CogPlugin-EstebanLorenzano.18 uuid: a53445f9-c0c0-4015-97a3-be7db8d9ed6b Mar 13 2013 With: NBCogit NativeBoost-CogPlugin-EstebanLorenzano.18 uuid: a53445f9-c0c0-4015-97a3-be7db8d9ed6b Mar 13 2013 Revision: git://gitorious.org/cogvm/blessed.git Commit: 412abef33cbed05cf1d75329e451d71c0c6aa5a7 Date: 2013-03-13 17:48:50 +0100 By: Esteban Lorenzano <estebanlm(a)gmail.com> Jenkins build #14535 Build host: Linux linux-ubuntu-10 2.6.32-38-server #83-Ubuntu SMP Wed Jan 4 11:26:59 UTC 2012 x86_64 GNU/Linux plugin path: /home/jimmie/Dev/Pharo/pharo2.0/bin [default: /home/jimmie/Dev/Pharo/pharo2.0/bin/] C stack backtrace: /home/jimmie/Dev/Pharo/pharo2.0/bin/pharo[0x80a0c0c] /home/jimmie/Dev/Pharo/pharo2.0/bin/pharo[0x80a0f28] [0xb76f240c] /home/jimmie/Dev/ForexConnectAPI-1.2.2-Linux-i686/lib/libForexConnect.so(_ZN18ServerCommunicator24connectToPriceFeedServerEPKc+0x62)[0x76f16632] /home/jimmie/Dev/ForexConnectAPI-1.2.2-Linux-i686/lib/libForexConnect.so(_ZN18ServerCommunicator13onReconnectedEv+0x3e)[0x76f175ee] /home/jimmie/Dev/ForexConnectAPI-1.2.2-Linux-i686/lib/libForexConnect.so(_ZN15CStatusListener27onTradeSessionStatusChangedEii+0xec)[0x76f153dc] /home/jimmie/Dev/ForexConnectAPI-1.2.2-Linux-i686/lib/libForexConnect.so(_ZN15CStatusListener6updateEPK12IUserSessionPK14ISessionStatus+0x89)[0x76f15479] /home/jimmie/Dev/ForexConnectAPI-1.2.2-Linux-i686/lib/libfxmsg.so(_ZN20UniversalUserSession16sendStatusUpdateEv+0x159)[0x76b94b89] /home/jimmie/Dev/ForexConnectAPI-1.2.2-Linux-i686/lib/libfxmsg.so(_ZN17UniversalRelogger21onReloginSuccessfullyEP17ITransportSession+0xf0)[0x76b90860] /home/jimmie/Dev/ForexConnectAPI-1.2.2-Linux-i686/lib/libfxmsg.so(_ZN17UniversalRelogger7reloginEP17ITransportSession+0xaf)[0x76b9098f] /home/jimmie/Dev/ForexConnectAPI-1.2.2-Linux-i686/lib/libfxmsg.so(_ZN17UniversalRelogger3runEPv+0x2f9)[0x76b90cc9] /home/jimmie/Dev/ForexConnectAPI-1.2.2-Linux-i686/lib/libfxmsg.so(_ZN9threading7AThread12threadRunnerEPv+0x1f)[0x76b9901f] /lib/i386-linux-gnu/libpthread.so.0(+0x6d4c)[0xb7693d4c] /lib/i386-linux-gnu/libc.so.6(clone+0x5e)[0xb75d1d3e] Can't dump Smalltalk stack(s).

[Pharo-project] I stumbled upon
by Friedrich Dominicus April 3, 2013

April 3, 2013

The following two functions: capitalized "Return a copy with the first letter capitalized" | cap | self isEmpty ifTrue: [ ^self copy ]. cap := self copy. cap at: 1 put: (cap at: 1) asUppercase. ^ cap and withFirstCharacterDownshifted "Return a copy with the first letter downShifted (in lower case)" | answer | self ifEmpty: [ ^ self copy ]. answer := self copy. answer at: 1 put: answer first asLowercase. ^ answer Well AFAIKT it should be first in the function (according to SLIME) But as one can easily see it's redundant code. How about a replacement like: withFirstLetterTransformed: aTransformBlock | result | self isEmpty ifTrue: [^ self copy ]. result := self copy. result at: 1 put: (aTransformBlock value: result first ). ^ result the above fucntions would get: capitalized "Return a copy with the first letter capitalized" ^ self withFirstLetterTransformed: [:value | value asUppercase ]. and withFirstCharacterDownshifted "Return a copy with the first letter downShifted (in lower case)" ^ self withFirstLetterTransformed: [:value | value asLowercase ]. Well I also know that capitalized is a very "old" thing but the second name is more specific. So what about: withFistCharacterUpshifted .... as counterpart? There's another thing which probably is incongruent: we have first for accessing the first element of any collection but first: is not for setting the first element. first:n yields the first n Elements of a collection. That's not a good name then. firstElements:n would be a better name IMHO. And then we could have first: someValue and so we would have in the end: result first: (aTranformBlock value: result first). would change the first Element of "any" collection. AFAIKT Lisp has such a convention... my first changes to not to any harm to existing Code, but of course changing the meaning of first: would.... Regards Friedrich

by Esteban Lorenzano April 2, 2013

Hi, I made some changes in the Pharo 2.0 release (can be called 2.0.1, but well... it is 2.0.596. in fact :) 1) Nautilus keybindings settings are now the old ones by default (asked by Stef) 2) Backported the fix that prevents that load FFI crashes image (thanks to Guille) 3) Backported the platform versions (thanks to... well, myself :) Now, there is a problem with the page because the big "Download" button still points to the portable version, but well... nothing is perfect in life :) enjoy, Esteban
