Re: [libvirt] [PATCH 5/8] save: let iohelper handle inherited fd

Rather than making the iohelper subject to a race in reopening the file, it is nicer to pass an already-open fd by inheritance. The old synopsis form must continue to work - if someone updates their libvirt package and installs a new libvirt_iohelper but without restarting the old libvirtd daemon, then the daemon can still make calls using the old syntax but the new iohelper. * src/util/iohelper.c (runIO): Split code for open... (prepare): ...to new function. (usage): Update synopsis. (main): Allow alternate calling form. * src/fdstream.c (virFDStreamOpenFileInternal): Use alternate form. --- src/fdstream.c | 32 ++++-------- src/util/iohelper.c | 142 +++++++++++++++++++++++++++++++++++--------------- 2 files changed, 110 insertions(+), 64 deletions(-)
