[Pharo-project] [Ann] Ephemerons for Cog

Well I'm hardly presuming to know, but if you have one dictionary acting as a global namespace. As far as I understood ephemerons, the problem is you have a single dictionary/namespace. Both the model and the view connect to an object. The model lets it go. The view doesn't. So this is an object you want to collect, because the model has let it go. This means you have a phantom reference that tricks the GC. That seems to me to be what ephemerons solve. I'm looking solely at the MVC Eliot mentioned, because shorn of context the description didn't mean anything to me. You have ephemerons to reveal the phantom reference. Bam - then the object gets collected. As this seemed to be all about dictionaries, which I take as being synonymous with namespaces if the model and the view were in separate dictionaries, then you couldn't have the problem that ephemerons solve. I wouldn't take me all that seriously here. I'm just trying to play around after reading Eliot's post three times. Smalltalk being folklore, I'm endeavoring to get you to talk about this just a little bit more. Chris

[Pharo-project] [Ann] Ephemerons for Cog
by Igor Stasenko May 24, 2011

May 24, 2011

I felt a bit hacky today and decided to implement Ephemerons. I tried to run it on both StackVM and Cog VMs, it seems to work fine (at least all 4 tests, which my brain were capable to produce, are green. ;) You can find the VM code on SqS/VMMaker in package: VMMaker-oscog-IgorStasenko.67 Also, i created a separate issue on Cog issue tracker to track it. http://code.google.com/p/cog/issues/detail?id=44 The implementation may contain a bugs. So, it needs review and testing. Now i would like all interested parties to give a feedback and help integrating it into our production images. -- Best regards, Igor Stasenko AKA sig.

[Pharo-project] SqueakDBX and MacOS X

Hi, I try to use SqueakDBX on Mac OS X 10.6. I have downloaded and compiled the libraries for PostgreSQL, MySQL and finaly compiled and installed openDBX. CPPFLAGS="-I/opendbx/PostgreSQL/9.0/include -I/opendbx/mysql/5.0/include" LDFLAGS="-L/opendbx/PostgreSQL/9.0/lib -L/opendbx/mysql/5.0/lib" ./configure --disable-utils --with-backends="pgsql mysql sqlite3" Now, I have in /usr/local/lib: -rwxr-xr-x 1 root wheel 17040 17 mai 09:10 libopendbx.1.dylib -rw-r--r-- 1 root wheel 32584 17 mai 09:10 libopendbx.a lrwxr-xr-x 1 root wheel 18 17 mai 09:10 libopendbx.dylib -> libopendbx.1.dylib -rwxr-xr-x 1 root wheel 1001 17 mai 09:10 libopendbx.la -rwxr-xr-x 1 root wheel 74624 17 mai 09:10 libopendbxplus.1.dylib -rw-r--r-- 1 root wheel 385056 17 mai 09:10 libopendbxplus.a lrwxr-xr-x 1 root wheel 22 17 mai 09:10 libopendbxplus.dylib -> libopendbxplus.1.dylib -rwxr-xr-x 1 root wheel 1054 17 mai 09:10 libopendbxplus.la and in /usr/local/opendbx : -rwxr-xr-x 1 root wheel 17232 17 mai 09:10 libmysqlbackend.1.so -rw-r--r-- 1 root wheel 38960 17 mai 09:10 libmysqlbackend.a -rwxr-xr-x 1 root wheel 1051 17 mai 09:10 libmysqlbackend.la lrwxr-xr-x 1 root wheel 20 17 mai 09:10 libmysqlbackend.so -> libmysqlbackend.1.so -rwxr-xr-x 1 root wheel 16904 17 mai 09:10 libpgsqlbackend.1.so -rw-r--r-- 1 root wheel 28624 17 mai 09:10 libpgsqlbackend.a -rwxr-xr-x 1 root wheel 1036 17 mai 09:10 libpgsqlbackend.la lrwxr-xr-x 1 root wheel 20 17 mai 09:10 libpgsqlbackend.so -> libpgsqlbackend.1.so -rwxr-xr-x 1 root wheel 16856 17 mai 09:10 libsqlite3backend.1.so -rw-r--r-- 1 root wheel 25936 17 mai 09:10 libsqlite3backend.a -rwxr-xr-x 1 root wheel 1053 17 mai 09:10 libsqlite3backend.la lrwxr-xr-x 1 root wheel 22 17 mai 09:10 libsqlite3backend.so -> libsqlite3backend.1.so ok... I have downloaded the OneClick distribution of Pharo 1.2.1 and installed SqueakDBX and GlorpDBX. Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfSqueakDBX'; load. ConfigurationOfSqueakDBX project latestVersion load. Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfGlorpDBX'; load. ConfigurationOfGlorpDBX project latestVersion load. Now, I try to do a SQL request to MySQL: connect | conn connectionSettings result | connectionSettings := DBXConnectionSettings host: 'mysql.domaine.fr' port: '3306' database: 'test' userName: 'username' userPassword: 'hello'. conn := DBXConnection platform: DBXMySQLPlatform new settings: connectionSettings. conn connect. conn open. result := conn execute: 'SELECT * from data'. DBXTranscript show: result. conn close. But I get an error : 'Unable to find function address' SqueakDBX didn't found the libraries ? I have try to copy the librairies in /usr/lib and /usr/lib/opendbx but with no results. In the Resources subdirectory, I have created a symbolic link to /usr/local/lib/libopendbx.dylib but without progress. ln -s /usr/local/lib/libopendbx.dylib opendbx I get the same error :-( If i modify the info.plist file to set the SqueakDebug key at 1 and the SqueakPluginsBuiltInOrLocalOnly key at false, I can see the search of librairies by the SqueakVM. The SqueakVM doesn't seem to try to load the openddbx libraries. You can download the log file at http://www.auverlot.fr/squeakdbx/squeakdbx.txt My previous tests under Linux have worked fine but i didn't find a solution with Mac OS X. Someone has an idea for help me ??? Thanks for your help. Best regards Olivier www.auverlot.fr

Re: [Pharo-project] paragraph replacement?

That is why I asked if someone knows how should the method behave. In older images (1.2), there is an #actOnClickFor: on the TextAction Hierarchy. TextDoit does for example: actOnClickFor: anObject "Note: evalString gets evaluated IN THE CONTEXT OF anObject -- meaning that self and all instVars are accessible" Compiler evaluate: evalString for: anObject logged: false. ^ true It seems the interface was extended to send the editor instance and the paragraph to the Link, so that a link could e.g. change what is displayed. What kind of TextAction do you have? You could just implement there whatever action makes sense (ignoring the editor and paragraph parameter and do exactly what #actOnClickFor: did in the old ST80 Paragraph). The whole TextAction stuff needs a pass... maybe with Moose as a Client, we can do that pass... Marcus -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe. Team RMoD.
