Re: [Pharo-users] Glorp / SQLite3 issue

Meaning none of Glorp's ~900 tests sends #login to a session object directly...? Ok, GlorpDatabaseLoginResource>>setUp looks like it asks the accessor to login. Transcript show: self class name asString, ' setUp'; cr. super setUp. self login: self class defaultLogin. accessor := DatabaseAccessor forLogin: login. accessor login. Looking around using Finder, seems this is how Glorp's test suite does the login. Try the following. It works on my computer. :-) I don't have the example book descriptor, so I'm reusing the test suite's. | workingDir dbName login accessor session | workingDir := SmalltalkImage current imagePath asFileReference parent fullName, FileSystem disk delimiter asString. dbName := 'sodbxtestu.db'. login := Login new database: UDBCSQLite3Platform new; host: workingDir; port: ''; username: ''; password: ''; databaseName: dbName; yourself.

After running the above snippet: sqlite> select * from GR_ADDRESS; ID|STREET|HOUSE_NUM 1|Alpha|300 sqlite> (The snippet is still low level, because it creates the DatabaseRow object explicitly.) Just for kicks, I ran the snippet a second time and got this: GlorpDatabaseWriteError: UNIQUE constraint failed: GR_ADDRESS.ID > UDBCSQLite3BaseConnection>>queryEncoding > ^#'utf-8' If #queryEncoding is a Glorp-specific thing, then from an architectural purity perspective I prefer to not have this in UDBCSQLiteBaseConnection which is intended to be a thin layer over the SQLite C API. Can you try the above method see if it works for you. Pierce

Spec Drag n Drop

by Marion Noirbent

Hello I would try to integrate the exemple Drag n Drop from http://spec.st/docs/drag_n_drop/ at the tutorial Building UI with Spec, so I have create a class in Pharo to try them and modify the code. I have found some of problems, I'm not sure if it come from strange configuration (i think about dragTransformationBlock: ), but it appear on the both version (my class and the original code). Marion, 1) Reproduce: Deplace the 'c' in the list of int, try to replace the 'c' in the list of char Error "nil not found in Orderred Collection" - Proceed don't remove the c from the list and make arrives a nil, like in the result deplaceReplaceC.png - Abandon seems work well, but the next refreshing of the list (by another move) make the nil appear too 2) Reproduce: Deplace the 3 in the list of char, try to replace the 3 in the list of int (at its place) Error " '3' not found in Orderred Collection" - Proceed duplicate the 3 gives the result DuplicateNumber.png - Abandon affect all number after the place, they "become" the previous number (BadNumber.png). Try to move the 4 make an error because it don't found 3, try to move the 5 make move the 4. 3) Reproduce: Deplace all items the list of int in the other Try to move the 'a' in the empty list of int Error "SubscriptOutOfBounds: 0" - Proceed remove the a from the list, but don't make it appear - Abandon seems work well

Re: [Pharo-users] OSProcess command - non responding image when calling often

by Sabine Manaa

Hi @mariano: "Did you test if the one-liner (Delay delaySchedulerClass: DelayMillisecondScheduler.) fixes these lookups? " -> my config loads materialDesignLite (which loads seaside and magritte). after loading this and trying the one liner, my image does not respond anymore. you can reproduce it when taking a new image and loading material design lite (no catalog entry yet) Gofer new url: 'http://smalltalkhub.com/mc/KevinLanvin/MaterialDesignLite/main' ; package: 'ConfigurationOfMaterialDesignLite'; load. ((Smalltalk at: #ConfigurationOfMaterialDesignLite) project version: #development) load. (proceed at the deprecated warnings for subString:) then try the one liner. Image does not respond anymore. @Paul, I took a new image, I loaded OSProcess from catalog browser and did the change. | aio | (aio := Smalltalk at: #AioEventHandler) ifNotNil: [ aio startUp: resuming ]. OSProcessAccessor initialize. "resuming ifTrue: [" self initializeThisOSProcess "]" (problem persists with and without code in ") 20 timesRepeat: [OSProcess command: ('echo "Hi there"').] No - the problem persists. I will stay at pharo4 for several weeks and the try again. If I can help fixing the problem I will do - please tell me what to do. Regards Sabine

Re: [Pharo-users] How much abuse can Teapot take?

by S Krish

Looked robust enough in my internal experiments.. I tweaked the Teapot further for easy implementation too.. Used it in my prototype with Angular JS thin framework.. works good. the limits seemed to be more dependent on the Pharo image limits nothing to do with Teapot per se.

Re: [Pharo-users] VOMongoRepository

by frankl1_miky

Thanks! I think that my image was in an incorrect state because even Monticello and Catalog browser was doing the same thing. After resetting the image image the problem was fixed. What can be the reason that broke my image? -- View this message in context: http://forum.world.st/VOMongoRepository-tp4900003p4900082.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

yes, but is just the connection reset problem. refreshing browser should correct it. and the amber debugger is there âby designâ :P Esteban > On 08 Jun 2016, at 21:02, stepharo <stepharo(a)free.fr> wrote: > > please post to the mailing-list. > > We do not have all the time to get present still having the information is important. > > > Le 8/6/16 Ã 15:06, Pierce Ng a Ã©crit : >> On Tue, Jun 07, 2016 at 06:42:04PM +0200, Esteban Lorenzano wrote: >>> Me >>> What happens? >> See screenshot I pasted in the #random channel. >> >> Pierce >> >> > >
