Re: [Firebird-devel] Semantics of release

 We can introduce some special mode to report such errors using exceptions,
 or write message into log, or even provide callback for debugging purposes.

 But Adriano's question was about *semantics*. So, do you agree with me 
 that
 explicit detach() must be called by good code and not just release() ? And 
 that
 call of release() when refCount == 1 is a bug in caller's code ?

 Hi, Marius!
 We need a new define for hurd

Do you need help in creating prefix.hurd_i386 file?

 afther we undefine LINUX that part compiles but i hit another issues
 that i found it to be in haikuos too

 g++ -I../src/include/gen -I../src/include -I../src/vulcan -DNAMESPACE=Vulcan 
 -gg
db -p -Wall
 -Wno-switch -DLINUX -pipe -MMD -fPIC -DFB_SEND_FLAGS=MSG_NOSIGNAL -D

A bit strange that I once again see -DLINUX here.

DEV_BUILD
 -pthread -DBOOT_BUILD -pthread -fno-rtti -c ../src/jrd/os/posix/isc_ip
c.cpp -o
 ../temp/boot/jrd/isc_ipc.o

 ../src/jrd/os/posix/isc_ipc.cpp: In function 'bool isc_signal2(int,

 ps here is one kvm-linux, qemu image that can be used

Sorry, now I do not have enough free time to experiment with hurd myself.
But will always be glad to help with advice.

 Initially I've planned to keep same approach for FB3. But I did not
 review latest Adriano's changes from this POV.

 I already show you that 2.5 yvalve is not thread safe. Once more.

 How do you expect this code to work concurrently?

 Accessing same memory, extending internal buffers, etc.

Good point, but I did not mean abuse of API. I only wanted to say that
under normal circumstances there are no race conditions that may cause
server to segfault/hang.

 I recently installed Firebird 2.5 on a FreeBSD, it was running ok
 until this moring when suddendly it stopped accepting connections.

 The server runs via inetd.

 Here is a copy of the last lines of firebird.log:

Should rebuild kernel with more SysV semaphores.

Thanks, I have to add that I'm using inetd instead of running the process on 
boot. Do you think the situation will improve if I run the server as a service 
instead of inetd?
