NBSQLite on Moose 5.1 connection problems

I tested on Windows, the sqlite3.dll is placed in the VM executable directory (folder of Pharo.exe). Unfortunately you just posted the stack trace - but not the error message that was displayed in the debugger. But as it failed already in the first API call (opening sqlite) I can only guess it is again the issue that the module was not found on your local machine. But you also said sometimes it workes and sometimes not. Mmmmhh. In case you have Sqlite cipher support already loaded you might have an issue after running the tests. I found the reason: The NBSQLCipher3ConnectionTest switches to sqlcipher support in #setUp but does not reset the class variable #Library in NBSQLite3FFI which is holding the module name back to 'sqlite' module in #tearDown). This was experimental stuff from Pierce anyway but it might have been in the config loaded already. I fixed this now in general by providing a #tearDown and updated the config with a new version 1.3 having also all latest packages. Fix is not optimal as when one is using sqlciper module the NBSQLCipher3ConnectionTest test switches back to sqlite then. But should be OK as most people use sqlite instead of sqlcipher and we discontinue NBQLite3 package starting with Pharo 5 anyway. (NBSqlite is not working with Pharo 5 because NB was dropped in favour of UFFI). So anything green here in the tests with latest config when I try in fresh images (Pharo 4/Moose 5.1). Also your example script works and outputs to the Transcript in both images. So please: ========== 1. load updated NBSqlite3 from config browser again in a fresh Mosse 5.1 image and try to provoke the error again 2. In case you still have trouble check what the expression: NBSQLite3FFI classVarNamed: 'Library' returns. It should give #sqlite3 on Mac and 'sqlite3' on Linux/Windows 3. If broken or the system still laments about the module you can even try to give the module with an absolute path: NBSQLite3FFI classVarNamed: 'Library' put: '/mypath/sqlite3.so' HTH Bye T.

NBSQLite on Moose 5.1 connection problems

by Offray Vladimir Luna CÃ¡rdenas

Hi, We have been dealing with a pretty strange and awkward problem in our workshops regarding the NBSQlite package and Moose 5.1 interaction. Some times it works, most times it doesn't, specially when I'm in the workshop. My solution was to unzip the sqlite package for the platform, copy sqlite3 as libsqlite3.so in the "bin/" directory of the platform and it worked (last week). Yesterday I tried the same in our workshop and if failed again even in my local installation. I tried copying and renaming (as "sqlite3.so", "libsqlite3.so") and put it where the moose image lives ("shared/") without any success. Is the biggest frustration in our workshops and we need to export as csv and read manually each useful query result in SQLite... and I can made sense of the error trace or why this error is happening. Monticello reports NBSQLite3-TorstenBergmann.26. Any pointer on how to solve it in a reliable way is welcomed. Here is the error log, while executing http://ws.stfx.eu/POQCW0NVKZJN: NBFFICallout(Object)>>error: NBFFICallout>>generateCall:module: [ :gen | gen callType: conv; sender: context; parseOptions: options; generateCall: functionSignature module: moduleNameOrHandle ] in NBFFICalloutAPI>>function:module: in Block: [ :gen | ...

Re: [Pharo-users] [Pharo-dev] Spotter Survey

by Offray Vladimir Luna CÃ¡rdenas

Hi some constructive comments on the survey: - I agreed with Nicolai: "before what?" I have chosen "Yes" supposing that is before filling out the survey. - I also think that the scale for evaluating relevancy on Spotter features is not the adequate, because some features are not shades of irrelevant or useful, but used accordingly to necessity and discoverability. In my case I don't use them because my use case don't let me discover that uses (which is kind of an irony: improving the own discoverability of a tool used for "external" discoverability). I have chosen "I don't know this feature" but sometimes I refer to I know them sometimes but is not clear how to pass from my use case to them.
