<youpi> neal: bad news: you remember the PTHREAD_RECURSIVE_MUTEX_INITIALIZER that points to a global __pthread_recursive_mutexattr? <youpi> that doesn't work <youpi> because some libraries like libstdc++ do not link against libpthread, while still using pthread_mutex_lock/unlock (counting on them being provided by either libc or libpthread-stubs) <CIA-1> sthibaul-guest * r626 pkg-hurd/hurd/trunk/debian/ (changelog patches/series): <CIA-1> * debian/patches/libpthread_rwlock_initializer.patch: Disable patch for now: <CIA-1> our initializer does not work when the application does not link against <CIA-1> libpthread. <CIA-1> sthibaul-guest * r629 pkg-hurd/hurd/trunk/debian/ (changelog patches/series): do not disable adding PTHREAD_RWLOCK_INITIALIZER, that's not the one that poses problems <CIA-1> sthibaul-guest * r630 pkg-hurd/hurd/trunk/debian/ (3 files in 2 dirs): <CIA-1> * debian/patches/libpthread_no_recursive_mutex_initializer.patch: New patch <CIA-1> to drop undefined references to __pthread_recursive_mutexattr. <youpi> I'm thinking about how to fix the PTHREAD_RECURSIVE_MUTEX_INITIALIZER <youpi> instead of a pointer to a static attribute variable, which posed problem <youpi> could we perhaps consider that page 0 is never mapped <youpi> and thus not only pointer 0 but also 1 2, etc. are invalid <neal> I think that is a good solution <youpi> and use them as special values <neal> alternatively, we could assume that -PAGESIZE is never valid <youpi> that makes us test it in all pthread_mutex_* functions, but it's not so bad <neal> I'm not sure which is better <youpi> why isn't it? <neal> because the kernel is mapped there normally <youpi> the kernel could be elsewhere <neal> true <youpi> in a 64bit adressing space for instance <neal> I think your solution is a good one <youpi> ok <CIA-1> sthibault * r633 pkg-hurd/hurd/trunk/debian/ (3 files in 2 dirs): <CIA-1> * debian/patches/libpthread_recursive_mutex_initializer.patch: New patch <CIA-1> to fix the recursive mutex initializers usage in libraries not linking <CIA-1> against libpthread.
