Re: [Pharo-users] Recommended logging API?

by StÃ©phane Ducasse

Hi sebastien it depends which level of logging you want to do. For simple internal logs use Object log else I would use toothpick Stef On Aug 12, 2011, at 12:42 PM, SÃ©bastien Bigaret wrote: > > Hi all, > > Is there a recommended package to use for logging? > I've found out that Object>>log exists and shoult be used instead of > Transcript>>show, and > http://www.mail-archive.com/setools@lists.squeakfoundation.org/msg00108.html > speaks about different packages or "adapters". > Is there a recommended one or a recommended way of doing it in Pharo? > (and/or a document I should read) > Thanks for any advice. > > __ SÃ©bastien.

Oops, sorry, I had missed the dedicated page in the collaborActiv book: http://book.pharo-project.org/book/LanguageAndLibraries/LoggingTools/?_s=DP… I guess it gathers the recommended approaches I was searching for. __ SÃ©bastien.

Recommended logging API?

by SÃ©bastien Bigaret

Hi all, Is there a recommended package to use for logging? I've found out that Object>>log exists and shoult be used instead of Transcript>>show, and http://www.mail-archive.com/setools@lists.squeakfoundation.org/msg00108.html speaks about different packages or "adapters". Is there a recommended one or a recommended way of doing it in Pharo? (and/or a document I should read) Thanks for any advice. __ SÃ©bastien.

MAConditionError opens a debugger

by Romain Verduci

Hi, I have a problem with my seaside application using MAConditionError. It's suppose to display a message error and in my case it opens a debugger. Code with MAConditionError : MAConditionError description: self description signal: 'Invalid name or password.'. I don't understand why it does this. To simplify the explanations and reproduce the bug, you can: - download my image on: http://demo.ovh.com/fr/466c8bec0e28467ab3d473647833e0e8/ - copy the service/ dir on your root dir (/) - run the image - go to localhost:8080/sh - try to login with a fake name And then the MAConditionError opens a debugger when there is an error in login. Thanks Romain

Re: [Pharo-users] DBXTypeNotSupoorted with Glorp

by Alain Rastoul

Hi Mariano I may be wrong, but I don't think that this issue is not related, I have first checked that reading my data with squeakdbx is ok. After searching a bit I think that the problem is in Glorp in DBXPlatform>>createDataTypesMap "Creates and returns a map that maps Smalltalk classes to SQL datatypes. The 16r means it is hexadecimal." ^Dictionary new ... at: 16rFF put: (DBXTypeNotSupported type: #UNKNOWN); Perhaps a solution would be I think it should be something like at: 16rFF put: (DBXTypeNotSupported type: UndefinedObject); with a fromDbxString method defined in UndefinedObject. fromDbxString: aString ^ convert the string to the true column datatype The problem here is that there should be a conversion from the string to the column datatype and the column datatype is unknown here... I don't know either if it is possible to get it from squeakdbx at this point (while fetching data) ?

Hi Alain. Do you know exactly which query is being sent? Do you think it can be related to this: http://code.google.com/p/dbxtalk/issues/detail?id=10 ? It seems that glorp stores a DbxTypeNotSupported in the column description for null values when the first row has a null value (the column datatype is varchar). Any workaround or advice is welcome before I dig into Glorp code TIA Alain -- Mariano http://marianopeck.wordpress.com

DBXTypeNotSupoorted with Glorp

by Alain Rastoul

Hi I 'm writing a small app with pharo +seaside + glorp + squeakdbx + sqlite and I have a problem reading null values from my database. It seems that glorp stores a DbxTypeNotSupported in the column description for null values when the first row has a null value (the column datatype is varchar). Any workaround or advice is welcome before I dig into Glorp code TIA Alain
