[Pharo-project] VM - Internet Settings?
by Geert Claes June 17, 2010

June 17, 2010

I would like to gauge how many Pharo-ers think that it would be great to have the Network/Internet Settings as part of the VM rather than the Image. I reckon the network setting are (just like display, sound, mouse and printer settings) dependent on the computer and environment an image is running on and not necessarily the image itself. -- View this message in context: http://forum.world.st/VM-Internet-Settings-tp2257076p2257076.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] HTTPSocket ... 407 Error
by Geert Claes June 17, 2010

June 17, 2010

I would like some help on how to configure the network settings to connect to the Internet on a network that uses an automatic proxy configuration script, because I am not sure how HTTPSocket uses (or should use) a PAC file. I managed to set (what I assume is) the proxy auto-config (PAC) file, using "HTTPSocket proxySettingsFileName:" but I still get the - not very helpful - "Error: Could not access ... blah blah". When I tried to debug it (still finding my feet here), I have been stepping through MCHttpRepository and HTTPSocket methods and I could not find anywhere where the PAC file was used at all? On the "stack top" in the httpGet method of HTTPSocket I did notice the "407 Proxy Authentication Required" error (see screenshot), but rather than that it seems to simply display a hard-coded "Could not access" message. Is the proxySettingsFileName used at all? Has anyone managed to connect using a PAC file? http://forum.world.st/file/n2258351/407_Error_-_HTTPSocket.png -- View this message in context: http://forum.world.st/HTTPSocket-407-Error-tp2258351p2258351.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] Pushed Cocoa Macintosh VM Squeak 64-32 5.7b1
by John M McIntosh June 16, 2010

June 16, 2010

Squeak 64-32 5.7b1.app.zip Follow the macintosh link from http://www.squeakvm.org/index.html This VM is built using the current (June 15th, 2010 version of VMMaker. This VM is setup to run in 32bit mode with a 32bit image. This VM uses the same plugins (excluding the 32/64bit FT2Plugin) as the 4.2.5b1 VM. I would suggest people take it for a spin, observe menu handling, drawing, sockets, file i/o, drag and drop, cmd line interface & sound. I'd like to move away from the 4.x.x VM to 5.x.x as we move towards getting things running on the iPad. So your help is needed to shake out the bugs. I've set the get Info to say to launch in 32bit Mode. This lets us use the existing plugins. If you really want to flip to 64bit execution mode you can uncheck the box. You will get a dialog at startup, and only the FT2Plugin is certified to work in 64bit mode. Things will run slower but maybe you'll think it's faster... Features: On resize we mangle the window bits (oh well). No doubt some more reading is required. We don't support 8bit video mode, oh likely only 32bit works. -- =========================================================================== John M.

[Pharo-project] seaside.gemstone.com down - unable to build 1.1-dev
by Torsten Bergmann June 15, 2010

June 15, 2010

http://seaside.gemstone.com/ss/metacello/ is down, therefore ConfigurationOfPharo can not be used to build Pharo 1.1. from an updated core. See http://downforeveryoneorjustme.com/seaside.gemstone.com Maybe the machine is switched to vmware.com? However - we should again think about reliable infrastructure ...

[Pharo-project] [ANN] Metacello 1.0-beta.27
by Dale Henrichs June 15, 2010

June 15, 2010

With the recent rash of SqueakSource/GemSource server downtime, I've bitten the bullet and updated the bootstrap process for Metacello to automatically switch to a secondary repository if the primary repository is not available. I also recommend that if you are maintaining a Metacello configuration that you update the class-side #ensureMetacello method for your configuration to use the primary and secondary repositories for loading the ConfigurationOfMetacello. A new version of the #ensureMetacello method can be found here (I've also updated the config template): http://code.google.com/p/metacello/wiki/EnsureMetacello If you are interested in using redundant repositories in your own Metacello project then you should take a look at this post: http://gemstonesoup.wordpress.com/2010/06/15/metacello-1-0-beta-27-unfurled/ as it describes the steps that you should follow.

[Pharo-project] A couple of memory management related questions
by Eliot Miranda June 15, 2010

June 15, 2010

Hi All, I've started working on a new GC for Cog and have a few questions. 1. does anyone have a copy of Joel Bartlett's J. F. Bartlett. A generational, compacting collector for C++. In E. Jul and N.-C. Juul, editors, OOPSLA/ECOOP â90 Workshop on Garbage Collection in Object-Oriented Systems, Oct. 1990. ? 2. what's the largest number of classes you've got in your most complex image and/or what's the largest number of classes you're ever created in an image? a.k.a. is 64k classes enough (16 bits), or is 1m classes enough (24 bits)? 3. do you have any personal recommendations, or example code, of systems that combine generation scavenging and/or compaction with object pinning? TIA, Eliot

[Pharo-project] maintaining state during parsing
by Ross Boylan June 15, 2010

June 15, 2010

During my parsing (with PetitParser) I'd like to retain some context as I go. A simple example would be the current line number, which gets incremented at line ends. A more complex example would be a current list of variables. I can avoid the whole problem by only retaining state after the parse tree is constructed, i.e., when I walk the tree. Is it just a bad idea to do anything else? The methods I've thought of, and their drawbacks are * use a global variable (ugly and requires only one active parse at a time) * keep the state in the stream I'm parsing with a special stream class that holds a regular stream and the state (not sure all parsers would have access to the stream; requires more hacks for parse: to work, as opposed to parseOn:) * make special parser subclasses, each of which refers to the shared state (lots of work and lots of extra classes; possibly I'd have one special parser that held the state and an arbitrary real parser) * black magic walking up the call stack (I think Seaside uses this, but I'd rather avoid black magic). Many of these approaches might also slow things down, particularly if I did quick and dirty implementations that used doesNotUnderstand: to do the delegation for the 2nd and 3rd options. Ross Boylan

June 15, 2010

Reported by nils.winter, Today (2 hours ago) WideString asByteString does not return a ByteString. Pharo image: Pharo Pharo core version: Pharo-1.1-11367-Beta Virtual machine used: Squeak 4.2.4beta1U Class browser used (if applicable): OBSystemBrowserAdaptor Steps to reproduce: 1. 'Ï' asByteString isByteString "false, shouldn't that be true?" Shouldn't that at least fail? I would suspect, that String>>asByteString should be something like asByteString | string | "Convert the receiver into a ByteString" string := ByteString new: self byteSize. 1 to: self byteSize do: [: i | string byteAt: i put: (self byteAt: i)]. ^string (copied that from asOctedString and replaced #size, #at:put: and #at: with their byte-versions ) btw: The display of 'Ï' seems to be broken on 1.1 is displayed as '?? and has some strange cursor issued but functionality is there

[Pharo-project] AutoStart startUp:
by Pavel Krivanek June 15, 2010

June 15, 2010

Hi, I'm synchronizing changes of the PharoKernel with Pharo 1.2 and I see that in the method AutoStart class>>startUp: the temp variable startupParameters is not initialized. Lukas deleted the line startupParameters := AbstractLauncher extractParameters. it should placed back as: startupParameters := SmalltalkImage current extractParameters. Cheers, -- Pavel

[Pharo-project] Alien for 1.1
by Noury Bouraqadi June 15, 2010

June 15, 2010

Hi, I failed to load Alien on 1.1. Then, I went to the googleCode rep and found that the issue was already reported. But, it's tagged for 1.2. Does it mean that we'll have to live without Alien in 1.1? see issues: 1360 ---- Accepted Add Alien in 1.2 Milestone=1.2 difficulty=Important 2452 ---- Accepted recreate special object array Milestone=1.2 difficulty=Important Noury
