[Pharo-users] OmniBase for Pharo 6

Thanks. I have made this change, but it does not affect the tests I have
run.

 

I have focused on getting the test suite in OmniBaseTests to run. So far I
still have 5 greens, 7 reds and one orange. The greens are all the first
five test methods in the browser list; it seems it half fails on the sixth
one (TestEquality), hence the orange, and then red for all the rest.

 

One problem is that the test database is created at the start of the test
suite, and then not removed at the end. This seems to mess up the next
attempt to run the tests. I tried to run the OmniBaseTests>>#tearDown
manually, but it fails, so I have to exit Pharo and delete the test database
in Windows.

 

I intend to continue running the test suite, but I shall run the tests
individually, and put breakpoints in those that fail. I shall report here if
I make any progress.

 

Best wishes

 

Peter Kenny

Peter: I think I found the problem. On ODBFileStream class >>
accessModeReadOnly the "o" on "only" is not capital. It is
^#accessModeReadonly  when should be ^#accessModeReadOnly ; so on the
ODBWin32FileStream >> createOn:  createMode:  accessMode:  shareMode:
cacheMode:  this part fails:

accessMode = #accessModeReadOnly ifTrue: [acMode := 2147483648
"GENERIC_READ"].

So it cant open the users file for read.  I have fix it and at least for now
I didn't get any "block" error.

Thanks for the hints. I now have 5 greens, but all the rest are red. I am
still getting the 'File cannot be locked' message. Are you doing better than
that? I may try a few trials using it for real, rather than the test suite.

 

Thanks again

Hi Peter, yes I had the same error at the beginning. I have done 2 minor
changes. Now it seems to be working fine (Although I am still running more
tests). Here: 

 

ODBWin32FileStream >> 

closeHandle: aHandle

"Close an open Win32 object handle, freeing any resources held by it.

Once closed a handle is no longer valid. Answer whether the function

succeeds.

See Win32 SDK help for more information.

 

BOOL CloseHandle(

HANDLE  hObject 

// handle of object to close  

);"

 

"<apicall: ulong 'CloseHandle' (long) module:'kernel32.dll'>"

^ self ffiCall: #(ulong CloseHandle(long aHandle))

 

 

 

ODBWin32FileStream >> 

lockFile: aHandle offsetLow: loPos offsetHigh: hiPos lengthLow: loLength
lengthHigh: hiLength

"<apicall: long 'LockFile' (long ulong ulong ulong ulong) module:
'kernel32.dll'>"

 

^ self

ffiCall: #(long LockFile #(long aHandle , ulong loPos , ulong hiPos , ulong
loLength , ulong hiLength))

I have just loaded Esteban's package in a new Pharo 6.1 under Windows 10. I
get an error message saying 'File cannot be locked. Try again?'. When I
select 'no', all tests are run and give red. Are you still running on win 7?
If so, I must be doing something wrong. Can you give more details of the FFI
corrections you made, please?

 

Many thanks

 

Peter Kenny

Esteban: it's working fine, I had to made a minor corrections on 2 FFI calls
and now everithing seems to be working fine.

For What I saw with Voyage-UnqLite only String Objects can be used to
searilize; Omnibase allow to persist almost any kind of objects, thats the
part I like about it.

I did it manually and I took like 5 min :P
but this was really easy, just a bunch of FFI calls.
