Well got a problem i gues... i got even more error's in my log files.. some about schannel processing error, or no route to host or get peer name... still everything looks to be working fine.. (got no complaints from the users) but these internal error's i get a fewtimes aday.. dunno, do i need to make a bugreport for it ? or do you need some extra debug info.. l8r Collen

...MBR logical partitions. Previously it only supported 4 MBR primary partitions and if you wanted more than that you had to use GPT. The ‘partition’ filter also supports MBR logical partitions. The ‘python’ plugin creates plugins which are compatible with Python >= 3.7. Tests are now run under MALLOC_CHECK_=1 and MALLOC_PERTURB_=<random>. This causes some tests to crash (silently) because of a shutdown race which needs to be fixed. Test shell scripts now have a generic ‘requires’ function to skip tests if features are not present. C99 type ‘bool’ is now used in most places where appropriate....

...2.6.9 on Fedora Core 6, 32-bit x86 architecture, I get frequent aborts due to a free() error detected by glibc. Error message is appended. The error is reproducible if I run with the exact same set of arguments, but if the file list to be transferred changes, it may work correctly. Running with $MALLOC_CHECK_=1 works around the problem. As far as I can tell, the errors come from the receiving rsync, not the sending one.

For these simple compile tests where we want to ensure that a basic external program could be compiled using libnbd, we shouldn't include <config.h>. This is because we want to test here that <libnbd.h> can stand alone, without needing anything defined by the GNU autotools infrastructure. Of course we can use <config.h> in other test programs where we aren't evaluating

These bindings get as far as running very simple connections. However there are many missing parts still: * No callbacks. * No functions which handle buffers (pread/pwrite!) This is posted just for general early interest, not even for review. Rich.

This feature is roughly finished now, although it needs a few more tests and some examples. It's pretty much up to par with all the other bindings, but it lacks a completely safe AIO buffer. It won't stop you from freeing the buffer too early) because golang's GC inexplicably lacks a way to declare a root from C. I can probably do it with a global variable and ref counting on the

Now runs a complete set of tests, notably including the AIO test. File descriptors are passed in and out as plain ints (instead of *os.File) for a couple of reasons: (1) We have to pass the plain int to syscall.Select. (2) Turning an fd into an os.File causes golang to set the blocking flag which is deeply unhelpful. Rich.
