Open Croquet will ahve issues in next version of Mac OS X

by LawsonEnglish

https://blog.krestianstvo.org/en/open-croquet-for-squeak-6/ <https://blog.krestianstvo.org/en/open-croquet-for-squeak-6/> This sounds really cool, but thereâs an issue coming up: Apple is doing away with ANY support for 32-bit apps and plugins and of course, Croquet is built for 32-bits and uses 32-bit plugins all over the place. Croquet could STILL be the killer-app for Smalltalk even though it never realized its potential in the past, and it wonât be able to if something isnât done about the looming 32-bit vs 64-bit issue. Need I point out that it should work on Pharo just the same way it does on Squeak? L

About #zipped / #unzipped

by Sven Van Caekenberghe

Hi, Given https://pharo.fogbugz.com/f/cases/21858/Cleanup-remaining-DeprecatedFileSys… [where we need more help !!] I found String>>#zipped to be one of the users of the deprecated RWBinaryOrTextStream. Although this usage is easy enough to fix, I think the current #zipped / #unzipped on String is broken. (note also that there are no real users of these methods) Right now it seems cool that the following is an identity. 'foobar' zipped unzipped. However, the result of zipping something is actual something binary (a collection of opaque bytes). Thinking of it, the input is actually also bytes, not unencoded characters. Of course, the current methods are broken, as can be seen from a more complex (wide) string. 'Ã©lÃ¨ves FranÃ§aises @ 10 â¬' zipped unzipped. >>> <something very weird> The error results from some implicit/wrong character encoding being used. The right way to do this is to explicitly encode/decode the string. (GZipReadStream on: (ByteArray streamContents: [ :out | (GZipWriteStream on: out) nextPutAll: 'Ã©lÃ¨ves FranÃ§aises Ã 10 â¬' utf8Encoded; close ])) upToEnd utf8Decoded. >From this it would follow that #zipped / #unzipped would make more sense on ByteArray. So that the above identity would become. 'Ã©lÃ¨ves FranÃ§aises Ã 10 â¬' utf8Encoded zipped unzipped utf8Decoded. This change of signature would be comparable to what we recently did with #base64Encoded / #base64Decoded What do you think ? Sven

Pharo Memcached client

by Sven Van Caekenberghe

Hi, I copied the (Pharo) Memcached client to https://github.com/svenvc/memcached where is lives in Tonel format with a Baseline and a working Travis CI build against an actual memcached server in the worker. More about memcached - https://en.wikipedia.org/wiki/Memcached - http://memcached.org Acknowledgements The original project can be found at http://www.squeaksource.com/memcached.html As far as I can see it was written by Philippe Marschall and Ramon Leon. I ported the codebase to Pharo. This repository is a recent copy with some cleanups. I intend to maintain this as I need it myself. The codebase should still maintain its original portability (minus the meta info, possibly). Sven
