...ollowing scenario: During program initialization, a global static object's constructor dereferences a ManagedStatic. During dereferencing of the ManagedStatic, it needs to know whether or not to acquire the global lock in order to allocate the ManagedStatic There are 3 possible types for the global_lock, and none of them solve the problem. 1) If global_lock is simply another global static, it may not have been constructed yet. 2) If global_lock is a raw pointer to a mutex, it would have to be explicitly allocated, and we can't guarantee this during static initialization. 3) If global_lock i...

I suspect this only allows one libguestfs handle per process into the critical section at once. I think the lock needs to be per-handle unless I'm misunderstanding what this is for.

Hi everyone, lately I've been getting familiar with library and working on slight re-layering of the library. It's about having locking layer in public API and tracing one layer below that (let's call it __t_ layer. I'm not very good at making up names, so this is temporary:) ). Then making sure that all generated public stuff call __t_ layer and all other internal stuff

Hello, I work at SmarctJog.com, we have here some patches on IceCast for performance and reliability, these are mostly client/connection/source cleanups (a slave merge is underway, and some more good stuff (c)), but we'd like this to be merged in before the list gets any longer. Please find attached a list of our patches with a short desc: This one is actually not from us/me, it was found
