using glorp and active record

by Sean Glazier

Hi, I have been trying to get glorp using active record working in pharo 5. I have a descriptor class for it and the classes inherit from active Record. I describe the table as: tableForAnswer: aTable | vistorId questionId | (aTable createFieldNamed: 'id' type: platform serial) bePrimaryKey. questionId := aTable createFieldNamed: 'questionId' type: platform integer. vistorId := aTable createFieldNamed: 'vistorId' type: platform integer. aTable createFieldNamed: 'answer' type: platform text. aTable addForeignKeyFrom: vistorId to: ((self tableNamed: 'VISITORS') fieldNamed: 'ID') suffixExpression: 'MATCH SIMPLE ON UPDATE NO ACTION ON DELETE CASCADE'. aTable addForeignKeyFrom: questionId to: ((self tableNamed: 'QUESTIONS') fieldNamed: 'ID') suffixExpression: 'MATCH SIMPLE ON UPDATE NO ACTION ON DELETE CASCADE' the table in the DB was preexisting. when I do Answer findAll I get and error that it is expecting a number for the id field. in the PostgresSQLPlaform serial is defined thusly. serial "For postgresql, we use sequences, and explicitly get the values ourselves, so just tell the database that they're integers." ^self typeNamed: #serial ifAbsentPut: [GlorpSerialType new typeString: 'integer']. What the DB hands back is 'nextval('answers_id_seq'::regclass)' which seems correct if it is telling me that there exists a sequence for this field and that is the correct command to issue for the field. am I defining this table incorrectly? or should I bag using active Record. I kind of liked it when working in Visualworks because there were also tools that would read in and describe the tables and then tools to assit when you needed to migrate to another version and do the changes etc. FYI this is the query that is being run that fails. SELECT t1.table_name, t1.table_schema, t1.column_name, t1.is_nullable, t1.data_type, t1.column_default, t1.character_maximum_length, EXISTS (SELECT DISTINCT 'x' FROM ((INFORMATION_SCHEMA.table_constraints s1t1 INNER JOIN INFORMATION_SCHEMA.key_column_usage s1t3 ON ((s1t1.table_name = s1t3.table_name) AND ((s1t1.table_schema = s1t3.table_schema) AND (s1t1.constraint_name = s1t3.constraint_name)))) INNER JOIN INFORMATION_SCHEMA.columns s1t2 ON (((s1t3.column_name = s1t2.column_name) AND (s1t3.table_schema = s1t2.table_schema)) AND (s1t3.table_name = s1t2.table_name))) WHERE ((s1t1.constraint_type = 'PRIMARY KEY') AND ((s1t2.column_name = t1.column_name) AND (((s1t2.table_schema = t1.table_schema) AND (s1t2.table_name = t1.table_name)) AND ((s1t2.table_schema = t1.table_schema) AND (s1t2.table_name = t1.table_name)))))) FROM INFORMATION_SCHEMA.columns t1 WHERE ((t1.table_name = 'answers') AND (t1.table_schema = 'public')) it looks as though it is reading in the schema and is expecting and integer because we told it to in the serial method on the PostgesSQLPlatform. As much as I love diving into these frameworks to figure out the deep inner workings, I really need to be getting data in and out without a fuss. Should I follow the DBX example where the descriptor is orthogonal to the model and one does not subclass from active record? I also note that not all the glorp tests pass. I think the were rather minor fails like timezone issues or something. It took a while but the test created a number of tables in the DB. So again Have I done something Obtuse that I qught to be slapped for here? thanks

Re: [Pharo-dev] ensure blocks in TestCase>>tearDown are not run if an error occurs inside ensured block when test itself was halted ...

by Dale Henrichs

Max, Thanks for looking into this. Do you think that this bug will be fixed in Pharo5.0? When I'm debugging the tests with this fatal pattern, my only recourse is to start and stop images between test runs ... The side effect of not running ensure blocks in tests is that a SharedQueue gets stuck waiting on an empty queue and when I interrupt that process (and get another debugger that is closed) I end up with the Empty Debugger problem where the debuggers have decide to stop working ... I saw that there was logic in Process>>terminate involved in dealing with processes running in critical blocks and that logic might be faulty as well ...

Re: [Pharo-dev] another segfault from Pharo5.0 vm (freshly downloaded today) Ubuntu 14.04

by Esteban Lorenzano

damn :( FreeType bug strikes againâ¦ :(( to be honest, Iâm playing with the idea to completely replace it with a UFFI version. I cannot find why/how this happensâ¦ in some conditions handle become invalid and pharo has no idea pointer is not valid any moreâ¦ then crash. Double free was what I guess but I do not find where that happens (the double free). And Iâm also open to believe in some memory handling problem in VM, now :(( Esteban > On 05 Aug 2016, at 22:55, Dale Henrichs <dale.henrichs(a)gemtalksystems.com> wrote: > > Attached crash dump file ... > > This one occurred after I'd had an image open for several hours interesting that similar to the other crashes I've seen recently FreeTypeFace seems to be implicated: > > Smalltalk stack dump: > 0xff7bc02c I [] in FreeTypeFace(FT2Handle)>pvtDestroyHandle 0xcdeae10: a(n) FreeTypeFace > 0xff7bc04c M BlockClosure>ensure: 0x9edc9b0: a(n) BlockClosure > 0xff7bc078 I [] in Mutex>critical: 0xadc7960: a(n) Mutex > 0xff7bc098 M [] in Semaphore>critical: 0xba42d50: a(n) Semaphore > 0xff7bc0b8 M BlockClosure>ensure: 0x9edcab8: a(n) BlockClosure > 0xff7bc0d8 M Semaphore>critical: 0xba42d50: a(n) Semaphore > 0xff7bc100 I Mutex>critical: 0xadc7960: a(n) Mutex > 0xff7bc124 I FreeTypeFace(FT2Handle)>pvtDestroyHandle 0xcdeae10: a(n) FreeTypeFace > 0xff7bc13c M FreeTypeFace(FT2Handle)>finalize 0xcdeae10: a(n) FreeTypeFace > 0xff7bc154 M ByteSymbol(Symbol)>value: 0xa3ab850: a(n) ByteSymbol > 0xff7bc178 M ObjectFinalizerCollection(OrderedCollection)>do: 0xaa62580: a(n) ObjectFinalizerCollection > 0xff7bc19c I ObjectFinalizerCollection>finalize 0xaa62580: a(n) ObjectFinalizerCollection > 0xff7bc1c0 I WeakFinalizerItem>finalizeValues 0xb8cae80: a(n) WeakFinalizerItem > 0xff7bc1dc M [] in WeakRegistry>finalizeValues 0xa6dd690: a(n) WeakRegistry > 0xff7bc1f4 M BlockClosure>on:do: 0x9edc8a8: a(n) BlockClosure > 0xff7bc214 M BlockClosure>on:fork: 0x9edc8a8: a(n) BlockClosure > 0xff7bc234 M [] in WeakRegistry>finalizeValues 0xa6dd690: a(n) WeakRegistry > 0xff7bc258 M OrderedCollection>do: 0x9edc450: a(n) OrderedCollection > 0xff7bc280 M WeakRegistry>finalizeValues 0xa6dd690: a(n) WeakRegistry > 0xff7bc29c M [] in WeakArray class>finalizationProcess 0xa5cefc0: a(n) WeakArray class > 0xff7bc2b4 M BlockClosure>on:do: 0x9edc398: a(n) BlockClosure > 0xff7bc2d4 M BlockClosure>on:fork: 0x9edc398: a(n) BlockClosure > 0xff7bc2f4 M [] in WeakArray class>finalizationProcess 0xa5cefc0: a(n) WeakArray class > 0xff7bc318 M WeakArray(SequenceableCollection)>do: 0xa381328: a(n) WeakArray > 0xff7bc33c I [] in WeakArray class>finalizationProcess 0xa5cefc0: a(n) WeakArray class > 0xff7bc35c M [] in Semaphore>critical: 0xcc147b0: a(n) Semaphore > 0xff7bc37c M BlockClosure>ensure: 0x9edb760: a(n) BlockClosure > 0xff7bc39c M Semaphore>critical: 0xcc147b0: a(n) Semaphore > 0xff7bc3c0 I WeakArray class>finalizationProcess 0xa5cefc0: a(n) WeakArray class > 0xbd19fe8 s [] in WeakArray class>restartFinalizationProcess > 0xce10050 s [] in BlockClosure>newProcess > > Looks like pvtDestroyHandle went a little overboard:) > > Dale > <crash.dmp>

Re: [Pharo-dev] when Cmd-P can just display a string in the debugger

by Nicolas Passerini

Hi, I think that whatever default behavior and shortcuts you decide, it would be nice to be able to configure it. So, if someone does not feel comfortable with the default, he has a simple way to change it and configure in a way that gets better along with his way of using Pharo. Don't you think?
