Re: [Firebird-devel] Firebird db integration big-endian LibreOffice unable to open little-endian embedded firebird db
Hi All, I've been doing some of the work on using the backup format for LO: Unfortunately we have no choice but to use the backup format as we have to have to be endian-agnostic. However speed shouldn't be too huge an issue as I suspect most users (when using a database embedded in a .odb) won't have huge databases -- for huge databases using an external database (either .fdb file or full server) would probably be reccomended in any case. For login details: we already use isc_dpb_trusted_auth, but only when connecting to a db: for the services manager we currently have notspecial parameters -- I've noticed there is also an isc_spb_trusted_auth, but the documentation suggests it shouldn't be used (I think using isc_spb_trusted_auth gave me some errors, but I might be remembering wrongly). However we've still not had any success in getting the backup service to work, the only error shown by isc_service_query is: gbak:Exiting before completion due to errors which doesn't really help figure out what is going wrong, I guess it might be needed to debug firebird itself to discover what we're missing?

It's possible to modify Firebird to be endian agnostic - I did it for a customer some years ago. Works fine for metadata and structured data, but there's no way to handle the contents of blobs. Firebird really doesn't know what's in a blob, so changing endianness would be a disaster. Historically, Firebird was created aware of endian issues because it ran on Vaxes and Intel machines. At the time, the performance impact of converting binary data on every reference was prohibitive. Then for a long time, different endian machines ran in different shops - not many mixed Mac, Vax, and Intel servers, so having databases of different natures was not a great problem. Then Apple switched endianness and the problem became slightly interesting again. Cheers, Ann -- CenturyLink Cloud: The Leader in Enterprise Cloud Services.

To be precise - please describe exactly what do you want from services, and I hope to be able to help you doing it. A. PS. Though Ann's suggestion seem to be much better, I'm afraid at least in nearest release you will have to use gbak. Is it possible to store both DB and gbak in order to avoid restore when endianess is the same? IMHO it's at least 99.99% of usage. PPS. For small databases gbak file is many times smaller than appropriate fdb (a lot of almost empty pages for system relations are not stored), therefore probably an option speed/size can be useful. -- CenturyLink Cloud: The Leader in Enterprise Cloud Services.
