Re: [Pharo-users] Memory Leak with Zodiac?

Even when not taking care of resource cleanup, for casual use #close to the socket will eventually be sent where necessary due to finalization. Helping a bit makes for better performance. Either one of the following would be better: 100 timesRepeat: [ ZnClient new beOneShot; get: 'https://www.google.com' ]. 100 timesRepeat: [ ZnClient new get: 'https://www.google.com'; close ]. | client | client := ZnClient new. 100 timesRepeat: [ client get: 'https://www.google.com' ]. client close. Now, Zodiac TLS/SSL Streams are more resource intensive: they create ZdcPluginSSLSession instances which represent native native data structures from the OS's SSL libraries. These are only cleaned up when #destroy is sent, which is one by ZdcSecureSocketStream>>#close. I didn't write any explicit code to do this by finalization, so that probably does not happen. Maybe we should experiment with adding a #finalize to ZdcPluginSSLSession as an equivalent to #destroy. It would be cool if you could test again. Hopefully memory consumption improves.

Memory Leak with Zodiac?

by CHRIS BAILEY

I'm having a little trouble with a possible memory leak with Zodiac. I'm running Pharo 1.4 Summer on Centos 6.3/Fedora 18 for deploy/dev. The plugin is using libssl.so.0.9.8, and I also seem to have another version kicking about which uses libssl.so.6 and am not really sure where I got that from. It may be an older one from the http://code.google.com/p/squeakssl/ site. Both have the same effect, i.e. when running 100 timesRepeat: [ ZnClient new url: 'https://www.google.com'; get ] VIRT and RES memory both go up about 70mb, but just using http doesn't accumulate any. I tried it in Pharo 2.0 which was the same, but the new NBCog doesn't include the libSqueaKSSL.so so I was only copying it over. Has anyone used it successfully in the same environment? I'll try it on Ubuntu when I get a chance. Thanks Chris

This is special stuff related to SSO: the other end, Google, Facebook, Twitter, etc, runs the authentication/authorization using their web apps, this is very hard, probably impossible to do with a programmatic HTTP client. >> Cheers >> Andy > > -- > Best regards, > Igor Stasenko.

Is there a platform independent way to launch a web browser from Pharo?

by Andy Burnett

I want to use Pharo's new OAuth capabilities to access google's spreadsheets. However, I don't want to build a webapp, I just want to authenticate, and then pull the data down into Pharo. In order to do this, I need to initiate a session, with a web browser. Do I have to use OSProcess for this, or is there a mechanism already built in? Cheers Andy
