[solved] Zeos 7.0.3-stable and Zeos 7.1-testing

[miab3]

EgonHugeist, mdaems,

Why ZDbcCache.pas from version 7.0.3-stable and 7.1-testing are so different at the moment?

michal,
because we did not want the new buffer management in version 7.0 that late. Normally this version has less size limits for number or size of columns. But I don't know the impact on other details like performance, memory usage,... in real life applications.
What I can say is that the test suite doesn't show any difference between the two versions. No extra failures, no memory leaks. But that's not real life.
Probably this will be the most important change for the 7.1 version, which is scheduled for the third quarter of this year. (That's when nothing happens to the current team) So don't hesitate to test this thoroughly.

miab3,

Michal, i broke with the old RowAccessor-behavior. Like you know did we've allways some Row-Size limitations. In my current stage i wasn't able to change the fixed size of the Buffer-Array but with some code-lines i only address all Strings/TBytes outside the RowBuffer. Now we've unlimmited Field-Sizes and can pick up 4096-Colums. IMHO that's enough since the most DBRMs can't handle more columns.

Like Mark wrote, we had a feature-freeze for the 7.0 series. All spezific changes features where made on Zeos7.1

Hello, i was trying to compile Zeos package under Lazarus 1.0.4 but get these errors:

C:\lazarus\packager\Zeoslib\ZEOSDBO-7.0.2-rc\src\compnent\ZAbstractConnection.pas(106,42) Error: Indentifier not found "TZControlsCodePage"

And in 7.0.3-stable:

C:\lazarus\packager\Zeoslib\ZEOSDBO-7.0.3-stable\src\compnent\ZDbcDbLibUtils.pas(113,1) Fatal: There were 4 errors compiling module, stopping.

¿Need any aditional unit where TZControlsCodePage is defined?

7.0.1 compile and install without errors (OK).

My interest is use Zeos to connect postgres 9.2 with Lazarus 1.0.4.

Sorry for me bad english.

Thanks and happy new year.

@jma_sp:
Probably you have mixed versions - make sure that all Zeos packages are installed from the same version - open and compile all five packages one by one from the same folder (from the folder where your Zeos 7.0.3 is) in this order:
1. zcore
2. zparsesql
3. zplain
4. zdbc
5. zcomponent

Now try to install zcomponent package.
Does it help?

[jma_sp]

Great, now is running:

1. zcore ------------> Compilation OK
2. zparsesql --------> Compilation OK
3. zplain ------------> Compilation OK
4. zdbc -------------> Compilation OK
5. zcomponent ----> Compilation OK / Installation OK

255 files generated in C:\lazarus\packager\ZeosLib\ZEOSDBO-7.0.3-stable\packages\lazarus\lib\i386-win32

Thanks

P.D:

So i write the result in this site in Spanish:
