Description

« Hide

I had to apply the following patches in order to make Firebird 2.5 RC1. Some are specific for the Debian/kFreeBSD architecture (that is GNU userland plus Debian package management over FreeBSD kernel), others are relevant for plain FreeBSD too.

freebsd-mutex-sysv.patch - makes mutex code use SYSV semaphores for mutexes on FreeBSD (same as DARWIN)

optional_posix_fadv.patch: use advisory posix features only when available. apparently the POSIX_FADV_* constants are not available on Debian/kFreeBSD

install_freebsd_as_linux.patch: use linux install makefile on k*BSD; the 'normal' freebsd install makefile misses the image/tar building targets

freebsd_targets.patch: fixes Makefile targets on FreeBSD. The current prefix file misses the fbsvcmgr and fbtracemgr targets

The FreeBSD kernel does not support process-shared mutexes. This match makes firebird use System V semaphores instead, similarly to Darwin (which is based on FreeBSD)

nbackup uses advisoru file fcntl in order to hint the OS in order to optimize the file access for sequential, one time reading. unfortunately the POSIX_FADV_* defines are not presend on Debian/kFreeBSD even of the function itself is present.

This patch makes advisory fcntl usage dependent on prresence of the respective POSIX_FADV_* defines.

FreeBSD's install makefile follows a different route than the Linux one and does not provide image/tar building targets.

This is a problem for the Debian/kFreeBSD package, because there is no way to create an isolated "install" .

Unfortunately I have no access to a "pure" FreeBSD so I can't say whether the patch is appropriate there.

add the missing fbsvcmgr and fbtracemgr targets to the freebsd prefix file.

The previous version of install_freebsd_as_linux.patch didn't work as expected on kfreebsd-amd64
