Re: [libvirt] [PATCH] Add parameter to wait for lock in file locking APIs

Our current pidfile acquire APis (virPidFileAcquire) simply return -1 upon failure to acquire a lock. This patch adds a parameter 'bool waitForLock' which instructs the APIs if we want to make it block and wait for the lock or not. --- Based on Daniel's comments on: https://www.redhat.com/archives/libvir-list/2014-March/msg00841.html daemon/libvirtd.c | 2 +- src/locking/lock_daemon.c | 4 ++-- src/util/virfile.c | 14 +++++++++----- src/util/virfile.h | 2 +- src/util/virlockspace.c | 6 +++--- src/util/virpidfile.c | 6 ++++-- src/util/virpidfile.h | 2 ++ 7 files changed, 22 insertions(+), 14 deletions(-)
