[ANN] SqueakSSL - a platform interface for SSL/TLS
by Andreas Raab 05 Oct '10

05 Oct '10

Folks - Since the weekend is over I've decided to release what I got so far and consequently I'm happy to announce the availability of a new interface to the platform SSL/TLS facilities for Squeak. SqueakSSL is a plugin-based approach which utilizes the platform implementation; currently the SCHANNEL SSPI on Windows and OpenSSL on Unix. To use SqueakSSL you need the following pieces: 1) The plugin for your platform. For Windows, you can download the plugin from http://squeakvm.org/win32/release/SqueakSSL.zip For Unix you'll have to compile your own; I'm attaching the relevant part of the platforms tree. Mac support is currently not provided but the OpenSSL based version can probably be adapted for Macs. 2) The SqueakSSL source code and tests. All of this can be found at http://www.squeaksource.com/SqueakSSL.html You need SqueakSSL-Core for the code and SqueakSSL-Tests for the unit tests (SqueakSSL-Plugin is the plugin source which you don't need and which we'll probably push into VMMaker). Once you've downloaded and installed everything correctly, you should be able to try SqueakSSL via the google example, which makes a query to encrypted.google.com: SqueakSSL google: 'Squeak'. If the query fails your plugin is probably not installed correctly (it seems unlikely that Google's cert has an issue :-) 3) For further tests (incl. the unit tests) you will need to provide a server certificate that can be used by SqueakSSL. On Unix you can do that using the openssl command line tools and once you've generated your cert, you can tell SqueakSSLTest to use the cert. On Windows the process is a bit more involved - you need to have a valid cert AND have it installed in the local certificate store (a description can be found at http://support.microsoft.com/kb/816794 but make sure you install it in your *user* account not the computer account). Once you have the cert installed, you can run the unit tests which should now succeed. Obviously, this is an early release and there's plenty of work that remains to be done, so help is welcome. However, it is starting to become useful and consequently I'm intending to update WebServer and WebClient soon for HTTPS support. Cheers, - Andreas

how to write to stdOut and stdErr under Cog
by Chris Muller 05 Oct '10

05 Oct '10

I am developing a simple "CommandLineProcessor" facade for easily transferring command-line arguments simply as block-arguments, so you can write smalltalk scripts in vi: CommandLineProcessor do: [ : arg1 : arg2 : arg3 | "args come in as Strings" ... ] and also for directing Notifications and Warnings messages to stdOut, and Errors to stdErr. It relies on OSProcess to write to stdOut and stdErr for this. However, ever since switching to Cog, writing to these streams does not seem to redirect out to Linux.. I don't know whether writing to these streams makes me Linux-dependent, but it really is nice to be able to write Linux scripts that employ Squeak in the back-end, but operate normally like other shell programs in the terminal window and with redirecting output, etc. - Chris

Anyone get the SqueakSSL plugin to work under Mac OS X Snow Leopard? Was Re: [ANN] SqueakSSL - a platform interface for SSL/TLS
by Chris Cunnington 05 Oct '10

05 Oct '10

The plugin doesn't work. It never has. This was acknowledged when it was released and I've seen no new announcements on a Mac plugin. Until John M MacIntosh as an objective third party says he has seen it work, I suggest you stop slapping your head against the wall. Chris

Multilingual input
by K. K. Subramaniam 04 Oct '10

04 Oct '10

Hi, I am trying to build a multilingual input decoder for Indic languages. The host locale is 'en' but keystrokes may contain Indic language codes in UTF-8 encoding. However, 'en' language is under Latin1Environment right now and assumes MacRoman for codes > 127. I suppose I could inject a global preference to resolve the conflict but only if it is absolutely necessary. Instead, I wanted to modify the Latin1 inputInterpreter to use UTF-8 decoder from UnixUTF8JPInputInterpreter on Unix when code > 127. Are there Unix VMs that feed MacRoman encodings into Smalltalk in evt third but keep 0 in evt sixth for Latin1 locales? Thanks .. Subbu
