search for: pthread_attr_destroy

A pair of patches to the xenstore library that: 1) blocks signal delivery before creating the watch wakeup thread 2) reduces the stack size of the watch wakeup thread.

These patches should be ready to go in now; I will also post my work-in-progress for enabling full parallel handling that depends on these, but with that series, I was still getting crashes or hangs with test-socket-activation (I think I've nailed all the crashes I've seen, but the hang is rather insidious; see my other email

Hello, I update my building scripts to build LLVM 4.0 RC1 (with clang, lldb, libc++, libc++abi, lld) on CentOS 6 and I got a lot of undefined symbols during linking LLDB.

Wherever we had code which did: if (something_bad) { perror (...); exit (EXIT_FAILURE); } replace this with use of the error(3) function: if (something_bad) error (EXIT_FAILURE, errno, ...); The error(3) function is supplied by glibc, or by gnulib on platforms which don't have it, and is much more flexible than perror(3). Since we already use error(3), there seems to be

This patch series is at the point where it basically now works. I can run the server with the memory plugin, and access it remotely using guestfish, creating filesystems and so on without any apparent problems. Nevertheless there are many

Also available here: https://github.com/rwmjones/nbdkit/tree/2020-windows-mingw-nolib After a lot of work I have made the port to Windows work without using a separate library. Instead, on Windows only, we build an "import library" (library of stubs) which resolves references to nbdkit_* functions in the main program and fixes up the plugin, basically the first technique outlined in
