[Pharo-project] Pharo 1.3 vs 1.2.1 some results for ConfigurationOfODBC
by Ben Coman Dec. 11, 2011

Dec. 11, 2011

I have a Microsoft Access database on Microsoft Windows that I want to process using Pharo. ConfigurationOfODBC looked promising so followed instructions at http://www.pharocasts.com/2010/12/access-database-through-odbc.html, though using a blank MDB file rather than SQLLite, and 'TestMDB' as the ODBC DSN, I executed... --8<--- Gofer new squeaksource: 'ODBC'; package: 'ConfigurationOfODBC'; load. (Smalltalk at: #ConfigurationOfODBC) load. connection := ODBCConnection dsn: 'TestMDB' user: '' password: ''. connection execute: 'CREATE TABLE user(name varchar(10), age smallint)'. connection execute: 'INSERT INTO user VALUES(''Old Bob'', 100)'. contents := (connection query: 'select * from user;') execute: ''. contents asTable inspect. connection close. --8<--- which failed on Pharo 1.3 but worked on Pharo 1.2.1. To debug this I compared each by single stepping 1.3 & 1.2.1 side-by-side. I executed... connection := ODBCConnection dsn: 'TestMDB' user: '' password: ''. which seemed to worked the same on both platforms up to the inserted 'self halt' shown here... --8<--- ODBCConnection>>connect "Connect to the database" self registerForFinalization. hEnv := self sqlAllocEnv. false ifTrue: [ self sqlSetEnvAttr: 200 value: 2 "SQL_ATTR_ODBC_VERSION" ]. self halt. hdbc := self sqlAllocConnect: hEnv. --8<--- ODBCConnection>>sqlAllocConnect: envHandle | h | h := SQLHDBC new. self checkSQLReturn: (ODBCLibrary default sqlAllocConnectEnvironment: hEnv connection: h ). ^h --8<--- ODBCLibrary(Object)>>sqlAllocConnectEnvironment: environmentHandle connection: connectionHandle "SQLRETURN SQLAllocConnect( SQLHENV EnvironmentHandle, SQLHDBC *ConnectionHandle);" <cdecl: short 'SQLAllocConnect' (SQLHENV SQLHDBC*)> ^ self externalCallFailed --8<--- ODBCConnection>>checkSQLReturn: sqlReturn "private - check the sqlReturn and generates an exception if corresponds" self checkSQLReturn: sqlReturn environment: hEnv connection: hdbc statement: nil --8<--- If you've followed the call chain down to here, then the result is... In Pharo 1.2.1 (WinXP & Win7) primitive SQLAllocConnect primitive succeeds, with sqlReturn=0 In Pharo 1.3 (WinXP & Win7) primitive SQLAllocConnect primitive succeeds, with sqlReturn=-2 I cannot find what -2 may mean on any of the Microsoft ODBC API pages, nor a few header files I checked (though I may have missed some header file) ================= To investigate further, I thought to try running the bypassed code... --8<--- ODBCConnection>>connect "Connect to the database" self registerForFinalization. hEnv := self sqlAllocEnv. self halt. true ifTrue: [ self sqlSetEnvAttr: 200 value: 2 "SQL_ATTR_ODBC_VERSION" ]. --8<--- sqlSetEnvAttr: attr value: value self checkSQLReturn: (ODBCLibrary default sqlSetEnvAttr: hEnv attr: attr value: value length: 0 ) --8<--- sqlSetEnvAttrPtr: hEnv attr: attr value: value length: length "SQLRETURN SQLSetEnvAttr( SQLHENV EnvironmentHandle, SQLINTEGER Attribute, SQLPOINTER ValuePtr, SQLINTEGER StringLength);" <cdecl: short 'SQLSetEnvAttr' (SQLHENV long void* long)> ^ self externalCallFailed --8<--- For both 1.2.1 and 1.3 'self externalCallFailed' is executed for 1.2.1 errCode=12 'No module to load address from' for 1.3 errCode=13 'Unable to find function address' --8<--- Pointers anyone? btw, In parallel I am also trying out DBXTalk.

[Pharo-project] [TODO 1.4] Issues tagged 1.4
by Marcus Denker Dec. 11, 2011

Dec. 11, 2011

http://code.google.com/p/pharo/issues/list?can=2&q=milestone=1.4 - All issues "FixReviewNeeded" needs to be looked at and reviewed. Does it fix the bug (or for an improvement: is this good? Do you want it in the release? - All issues "NoSourcesAvailable" do have fixes, but described in wonderful prose. ("change the third character of the second line.." (nearly...). The idea here is that it's far far far far easier to look at things that one can just load in the system as opposed to solve a textual riddle first. yes, it's trivial... but it's amazing how the triviality between "machine readable code" and "textual description for a human to parse" changes how long an issue is not looked at.

[Pharo-project] keymapping problem: pasting in a pluggable text morph
by Tudor Girba Dec. 11, 2011

Dec. 11, 2011

Hi, I am trying to handle pasting in a PluggableTextMorph, but there seems to be a problem induced by Keymapping. Consider the following simple case: morph := (PluggableTextMorph on: StringHolder new text: #contents accept: #acceptContents:) autoAccept: true; color: Color white; yourself. morph openInWindow In the regular Pharo image it behaves as expected: - If you type some text, it gets auto accepted (there is no orange triangle on the top right) - If you use Ctrl+v, it auto accepts - If you use Cmd+v (on Mac) or Alt+v (on Windows), it also auto accepts. When Keymapping is loaded we have a problem: - If you type some text, it gets auto accepted (there is no orange triangle on the top right) - If you use Ctrl+v, it auto accepts ===> But if you use Cmd+v (on Mac) or Alt+v (on Windows), the orange triangle appears. If you inspect the contents, indeed they are not updated. I tried to look into this, but I did not manage to get to the bottom of this. Can anyone help?
