This is right only for those who set up READ COMMITTED transaction isolation

And it isn't default now. You have to explicitly set different TIL to get
such
behavior. Default TIL (concurrency) works correctly.

If plugin can get its configured (not given by developer) name, then I would
suggest
following syntax for databases.conf:
MyDB = MyDB
{
SomePlugins = aaa,bbb,ccc
aaa = {
Foo=Bar
}
bbb = {
Foo=Rab
}
}
Plugin can get its parameters by using
IConfig->find(MyName)->getSubConfig()->find("Foo")->getValue().
If parameters are not configured on database level, it should get global
ones from
plugins.conf.
BTW, I don't like so long call chain. I would prefer simpler
IConfig->asSubConfig(MyName)->asString("Foo","My default")

AFAIU, if I want to return from my plugin, for example, error "Configuration error, output directory is not set for database XXX", the only way to do so is to form complete text and then push isc_random into status array.

"The trap with the XSQLDA solution is that it encapsulates both the location of the data and their format, making it possible to change location or format (or both) between fetch calls. Hence, the need for the BLR wrapping in every fetch call". Cheap trick. The first part is true, but it does not make true the rest. There is no need to send BLR on server on every fetch. Actually, there is no need to send BLR at all. Client library is clever enough to do data coercion (or throw an error).

The first thing that every method of every interface have to do is to check versions of every interface it got as parameters and upgrade them if necessary. Otherwise new plugins will crash with old engines/applications when use new methods. Upgrading causes allocation of new VMT which (AFAICS) is never released. Upgrading doesn't replace getVersion() address in new VMT which means that even upgraded interface will return old version and will be upgraded again and again on the next call. -- WBR, SD. -- Infragistics Professional Build stunning WinForms apps today!

I always thought that get() is a stub for backward compatibility made because of lack of time for thinking. Actually, I still think so. Ask yourself: what status is used for by app developers? As a one of them, I know only two purposes: 1) Get error text to show to user or write to log (may be via throwing an exception) 2) Check that a definite error code is inside and get its parameter(s) None of these tasks are solved neither by get(), nor by getErrors(). I would suggest for IStatus following methods: int check() - returns 0 if status is empty, 1 if has warnings and 2 if has errors char* getText() - return fully interpreted text ICode* getCode(ISC_STATUS code) - return object encapsulating a definite gdscode block or NULL if such code isn't inside -- WBR, SD. -- Infragistics Professional Build stunning WinForms apps today!
