[Firebird-devel] Test bugs.core_3554 randomly fails
Hello, all. As most of you know, when routine protocol.cpp:alloc_cstring() receives zero length, it behaves differently, depending on previous allocations. In some cases it returns pointer to zero-length string, in some - NULL pointer. Because of this, used in subj test query "EXECUTE STATEMENT ''" can throw different errors. If the routine has returned NULL, user will get code 335544608 from Y-valve, otherwise it will be set of 335544569, 335544436, 335544851 from DSQL. In first case the test will fail, as it always expects the second case. Is it a problem in the test or in the server? -- WBR, SD. -- What NetFlow Analyzer can do for you?

[Firebird-devel] Problem with Firebird 2.1 embedded and libncurses 6 (Linux)
I have developed a couple of open source programs that use Firebird as an embedded database. The programs are some years old so they use version 2.1. I am using an embedded setup under Linux with a copy of Firebird that I compiled at the time and everything worked fine until now. I compiled in an old distribution and I created an archive file that contained everything is needed to run the programs: in this way I have been able to have a single file that worked on every distribution. I do not have the resources to build custom versions for different distributions. Now some users are reporting that the program does not run under newer distributions because those distros ship with libncurses 6 and firebird has been built against version 5. The problem can be solved by installing the libncurses 5 package but it looks like this package is not available under Arch, for example. Moreover not all users are experienced enough to install that package. Of course I might build Firebird in a distribution using libncurses 6 but this would require doubling the effort and users ought to know which version to download. I think that a solution might be to statically link libncurses with Firebird but I don't know if it would work. I checked and the following files link to libncurses: libfbembed.so intl/fbintl bin/fb_lock_mgr do you know if it is safe to statically link libncurses? My Linux knowledge is rather limited: if statically linking is safe do you have suggestions on how to do it? Should I change something in the makefiles or should I use some ambient variable or should I do something else? Thanks in advance Fulvio Senore -- What NetFlow Analyzer can do for you?
