[Pharo-project] Speeding up Finder string search
by Stefan Marr Jan. 17, 2012

Jan. 17, 2012

Hi: The finder is annoyingly slow when doing string searches. Compared to a 'grep' its multiple magnitudes slower, at least from my perception :( Profiling pointed my at RemoteString>>string and its use of readOnlyCopy on the SourceFiles. I put a cache of these read only files into ExpandedSourceFileArray and get a nice speedup. { [ Finder new constructSourceDictionary ] timeToRun. [ Finder new constructSourceDictionary ] timeToRun. [ Finder new constructSourceDictionary ] timeToRun . } Without Cache: #(32079 29034 32274) With Cache: #(10757 10718 11050) While that works for the searching, it does fall apart for other uses of RemoteString>>string. (For instance, filing out the changes...) If anyone has an idea how to avoid the overhead of copying, I would be all ears.

[Pharo-project] Exception logging
by StÃ©phane Ducasse Jan. 17, 2012

Jan. 17, 2012

Hi guys when I do the following |file| [ file := StandardFileStream fileNamed: 'loglog.txt'. file nextPutAll: 'Start'. [ file nextPutAll: (Compiler evaluate: '55 + 88 poipuiu') asString] on: Error do: [:ex | ex outer errorReportOn: file]. ] ensure: [file close]. I get a pop up DNU poipuiu while I would like to get the stack on the stream. May be my mistake is obvious but I do not see it. Stef

[Pharo-project] Design change possible with fast SSD's possible?
by Guido Stepken Jan. 17, 2012

Jan. 17, 2012

Hi! I am just reviewing some timing adjustments in Linux, which came neccessary due to the tremendous speed improvements of SSD Raid, > 1 mio IOPS, compared to fastest Barracudas disks with > 200 IOPS max. IS there still a "Image" neccessary in Smalltalk then? Or has this former "design approach" nowerdays rather significant disadvantages? (32 Bit, hanging IO during sync, GC....)

Jan. 17, 2012

Hi, does anybody have experience with CogVM on 64bit Fedora? I'm currently using Fedora 16 and prebuild vm doesn't work (says that there is some problem with x11 plugin). Is there any simple method how to run it? Or any simple method how to build it from sourcecode? Jan

[Pharo-project] Scat - Public Release and announcement
by Bernat Romagosa Jan. 17, 2012

Jan. 17, 2012

Hi list, Joan GÃ¼ell and I have been working on Scat -the Scratch port to Pharo- quite a lot recently. We wanted to push it to a point where we could release the first reasonably working version, which we've just managed today. Please take a look at the release announcement<http://code.google.com/p/scat/wiki/PublicRelease> (which should be read in a bit of a humorous tone), in which we explain what's up with the project and what future is left for it. For the tl;dr version, please read: - Many things are working, many aren't, but the state of the project allows us to move into more interesting stuff based on the graphic programming metaphor. - Scat is a time-consuming, brain-smashing, life sucking-project. - We no longer will be maintaining this massive unmaintainable code. - Suddenly: free time for other projects! Cheers everyone! -- Bernat Romagosa.

[Pharo-project] Styling in Inspector
by Guillermo Polito Jan. 17, 2012

Jan. 17, 2012

I added the following method to inspector and styling turned on: shoutAboutToStyle: aPluggableShoutMorphOrView ^ true Should we add it? Also, I've tryed to remove the styling from the PreDebugger window on warning messages by setting it a NullTextStyler and it doesn't work :). I'll continue hacking.

[Pharo-project] loading subclasses of non existing superclasses with Monticello
by Mariano Martinez Peck Jan. 17, 2012

Jan. 17, 2012

Hi guys. I noticed that when loading a package with classes whose superclasses are not present in the image, and the Monticello popup appears, then those subclasses are not loaded at all. I think I remember they were loaded anyway as a subclass from an obsolete class. But I have just checked in pharo 1.2, 1.3 and 1.4 and the subclasses are not loaded at all :( So...I am just crazy or it used to be that way and then it changed? thanks -- Mariano http://marianopeck.wordpress.com

[Pharo-project] reading *exactly* n bytes from socket
by Max Leske Jan. 16, 2012

Jan. 16, 2012

Hey guys I'm having a problem with Socket / SocketStream. When I know that the next packet of data from the server is going to be 10'000 bytes I want to ask the socket for exactly 10'000 bytes of data (I don't care how long it takes). However, the comments in the Socket class suggest that the buffer might not be filled entirely when the message answers. As a consequence, my code fails because the ByteArray sometimes has a number of zero bytes at the end which obviously wasn't expected. I also tried to use SocketStream to get around this problem but wasn't successful. Am I supposed to handle this case myself or did I overlook something? Cheers, Max
