Hi,
Support for ZEROSPACE in WorkSpaceList() is trivial but can be implemented
only in C. I can add it in necessary. BTW please check above two example
with xbase++.
Would you please implement the WorkSpaceList() with ZEROSPACE ...
I need to obtain all alias within ZEROSPACE ....
Or any way to get a list of all alias within the ZeroSpace ???
I have a related question/problem. Let's say I want to transfer areas
among threads (that's the purpose of alias detaching). I'm missing two
functions:
1) to attach alias within another thread using a different alias name;
2) to search a "zerospace" for a specific area having some dbf file,
some open mode, index, etc.
These missing functionality could be reached by function which renames
current alias. F.e.:
USE items NEW ORDER number READONLY ALIAS items1
....
HB_DBSETALIAS("items_number_RO")
HB_DBDETACH()
Another thread:
HB_DBREQUEST("items_number_RO",,, .T.)
HB_DBSETALIAS("items_ro")
...
This could be a waste dynsym table if I want add a random HTTP session
number to a database name before detaching it (let's say I want to cache
opened tables for HTTP session). It this case I find a useful solution
to store a required (for reattaching) data in cargo field. F.e.:
USE items NEW ORDER number READONLY ALIAS items1
....
HB_DBDETACH(, "items_" + cSession)
Another thread:
HB_DBREQUEST({|alias,cargo| IIF(cargo == "items_" + cSession, (alias
:= "items_ro", .T.), .F.)},,, .T.)
...
/* Here block is a kind of search block. It also assigns a new alias
name */
The second proposed solution is more flexible, but is not optimal
because it keeps a long mutex lock on "zerospace" internals.
Regards,
Mindaugas
