Re: [Pharo-project] Databases with full text search support

by Diogenes Moreira

In this case, the better solutions could be is a NoSql Database such as CouchDB.. or other document oriented DB.. if I remember well, exists a seaside couchDB integration.. Best.

Re: [Pharo-project] About FileSystem (probably not for 1.3)

by StÃ©phane Ducasse

Hi max I started to merge some of your changes to FS. Now I was wondering about this one: ***for my work on GitFS I needed a resumable exception (alternatively an ifPresent block would have done the trick but that would have ment more meddling with Filesystem) to delete existing files when copying. The following changes are a result of introducing this exception to the copy methods. *added class FSFileExistsResumbale and its superclass FSFilesystemException to support the changes to the copy methods *#copy:to: signals FSFileExistsResumbale instead of FSFileExists *FSCopyVisitor>>copyDirectory uses #ensureDirectory instead of #createDirectory *needed to change FSFilesystemTest>>testCopyDestExists to expect FSFileExistsResumable *FSReference>>basicCopyTo: signals FSFileExistsResumable instead of FSFileExists Could you explain us a bit more?

I'm interested in your findings. Did you also ask in squeak?

Re: [Pharo-project] Databases with full text search support

by Miguel CobÃ¡

There isn't a full solution that I know of, but maybe you can use lucene to store index info outside smalltalk and use the references to search for the real smalltal objects. There are also bindings for several nosql databases for lucene and solr like mongo db and cassandra and there are bindings in smalltalk for mondodb and cassandra.

[Pharo-project] Databases with full text search support

by laurent laffont

Hi, I need to have full text indexing and searching over a 3-5 million documents. Actually the products I work on are written in PHP - MySQL. What would you use (open source - mandatory - our products are open source) in Smalltalk world to do this ?

We could ignore the errors, but hiding bugs is a bad idea IMHO. We can add a check too, but what can you say about the following anomalies in the trait implementation? | justATrait | justATrait := TPureBehavior. justATrait isTrait. "true ok" justATrait isBehavior. "false strange" justATrait allSuperclasses. "an OrderedCollection() ok if there should be none" justATrait withAllSuperclasses. "an OrderedCollection(TPureBehavior) ok, but the comment says it should contain Object too" justATrait subclasses. " #() acceptable" justATrait superclass. "Error WTF?" Btw, what happened to the clipboard in Pharo 1.2 on windows? If I copy text, the line endings are CRs, not CRLFs, so the text is a single line. Levente >

Traits implement (via > TPureBehavior) #allSuperclasses, #withAllSuperclasses, etc., but lack > #superclass. So which implementation of #superclass would you recommend for Trait, which would keep O/ECompletion working without modification? I can't think of any which makes sense really. IMO, if code in the component eventually needs to be changed to not raise a debugger, it's related. Cheers, Henry

The bug is not related to OCompletion. Traits implement (via TPureBehavior) #allSuperclasses, #withAllSuperclasses, etc., but lack #superclass. Also note that these methods are not in sync with their comments. Btw it's a bit strange (but acceptable) that Traits are not Behaviors.
