Re: [Pharo-users] Best/simplest way to read and write to a MySQL database

by Andy Burnett

á§ Thanks everyone, I shall try the DBXTalk approach. It seems as though it is being actively developed. As a side note, I think it would be great if Pharo could identify a 'main stream' route for dealing with RDBMS. It would be similar to the way in which Zinc is the main way to do http etc. I wouldn't want to discourage anyone from doing interestng experiments, it's just that a main stream route would help people to get going. Cheers Andy

Changed semantics for mongo ObjectID

by Norbert Hartl

I needed to change the way ObjectIds are read from and written to BSON. BSON is a format that encodes its byte contents little endian. In mongo database the format of ObjectIds is different. The way an ObjectId is encoded is big endian. You can see this if you compare the outputs for an object when read from mongo shell and from pharo. The ids wonât match. If you do ânormalâ stuff with mongo it is unlikely you have noticed the effect. An OID is read the wrong way but also written the wrong way which makes it right again from the mongo database perspective. But it wonât work if you use a mixed query setting. Meaning reading an OID and requesting the database using javascript expression. This will fail. Iâm writing this because Iâm not sure the change can break existing software. The change is not included in the stable version, yet. If you want to test then load #bleedingEdge and report any problem that might occur. I will use the new behaviour and will take the freedom to make it stable if it works for some time. FYI, Norbert

Thanks for your reply Stef, I know that to work around Morphic like Spec does is a hard task. I doubt that my skill in Spec are high enough to provide great solutions but if reporting problems i encountered may already help, i do ;).

Do we migrate the code to SmalltalkHub and add some configuration? I know that Olivier told me that he uses a direct mysql driver (or I confused it with another one).
