The week began in storm with the Jim Starkey (interbase father) letter in wich he express his opinions about current state of code we got from Borland (version 1.0.2) :"As most of you know, I've adopted an arm's length policy towards Firebird. It's not my product any more, it's yours. I've tried to keep my involvement to a relatively lofty architectural level, offering advice when solicited, and letting the chips fall where they may.

Stated policy notwithstanding, Ann asked my help finding an obscure event delivery problem for a customer on the verge of bleeding to death. Other than the odd peek to refresh my memory, this is my first involvement in the code base since I left Interbase in 1991.


interbase has two mechanisms to deliver event notification. On systems that supportthreads, the remote interface starts a thread that listens on an auxiliary port for an event notification message. On system that don't support threading (or don't use threading), the events first written to the auxiliary port, then a 1 byte out of band packet (MSG_OOB) packet is sent to deliver a SIGURG signal to client, and the signal handler reads the event packet and delivers the event notification at signal state.The first bug is that the Linux multi-threaded client was asking for and getting ptype_out_of _band. This caused the server to send a one byte out of band packet following each event notification message. In theory, while sloppy and inefficient, this should have been benign. An apparent Linux networking bug, however, occasionally interjected the out of band byte into the regular socket stream, effectively corrupting the stream. I haven't probed the boundaries"

Blas Somoza stoped the cleaning activity on cvs tree because we heading to the first Release Candidate for V1.5 ,this week he got parse.cpp build with bison :"After some work I get parse.cpp build with bison and maintaining yacc compatibility (with the MINGW port)."

FirebirdSQL In the News ==

Firebird is mentioned in an article on open source databases in InfoWorld http://www.infoworld.com/article/03/03/07/10osource_1.html : "Another open-source database that is beginning to turn heads is Firebird (firebird.sourceforge.net/). Born of the opening of Interbase's source code, Firebird seems to be gathering fans in the open-source world. Given Interbase's long history, Firebird is quite mature for a relatively new open-source entry."
