I'm inquiring and it seems related to bad handling of author/timestamps.

Let's see the lowest: (CompiledMethod allInstances select: [:e | e fileIndex = 1]) detectMin: [:e | e filePosition] (AColorSelectorMorph>>#color: "a CompiledMethod(894697472)") filePosition 468 Now, let us see what is in the source file: (SourceFiles at: 1) position: 0; next: 468 '''From Pharo1.0beta of ''''18 October 2009'''' [Latest update: #10487] on 19 October 2009 at 6:18:53 pm''!

I have some idea who the squeaksource.com admins are, but not the source.squeak.org admins. Also don't know who else has their own squeaksource install -- Matthew Fulmer (a.k.a. Tapple)

Re: [Pharo-project] Getting a functionning unstable image

Hi nicolas this is strange because I always update all the updates from the latest unstable published by marcus (so yes it can be long) and I never get this error. May be you have a broken sources files or something like that. I update often multiple times especially when I integrate changes to make sure that I do not a strange changes around. and I never get such error. What is your OS?

What we should do, too is to invest into the regression tester to acutally test things like if the changes and sources are in a good shape, if we can condense, write new sources, all these things... -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe.

[Pharo-project] Getting a functionning unstable image

by Nicolas Cellier

Hi guys, Updating Pharo from the update stream failed many times and keep on failing for me... But maybe it's just me... So I picked the unstable link from the web site (http://www.pharo-project.org/pharo-download/unstable-core) This drives me to a 13091 image. The first thing I do is select the 'update system' menu... Err, it fails... It seems related to broken sources... Well the image points to which source file ? can't remember the incantation, let just browse it... Err, no source, I can't browse. No matter, I set the browser to decompile mode... Err, this does not work, I still can't browse code. Hmm very bad starting experience, I know what unstable means, but I was dreaming of other words like continuous development. So ket's open an older image (my own updated 1.2) to find the incantations. (Scanner>>#scanTokens:) fileIndex -> 1, so it seems that the source file is corrupted. (SourceFiles at: 1) -> MultiByteFileStream: '/Users/nicolas/Smalltalk/Squeak/pharo/PharoV10.sources' Well, for my previous Pharo images, this very file works ! How damned can be the file be changed and the version not incremented ? Is it me who did something wrong ? Or the update process somewhere did condense the sources ? Or did someone elese messed with the sources ? Is it a known problem ? Any help appreciated. Nicolas

[Pharo-project] String>>#base64Encoded

by Sven Van Caekenberghe

Hi, It took me quite some time today to figure this out and it might be relevant for others too: it turns out that String>>#base64Encoded introduces newlines which you definitively do not want when doing Basic HTTP Encoding for example. The tricky part is that it works when you stay below a certain length. This can easily be solved by invoking Base64MimeConvertor with the #mimeEncode: <string> multiLine: false Zinc HTTP Components now does this consistently through ZnUtils class>>#encodeBase64: Sven
