[libvirt] [PATCHv2 0/5] build: update gnulib
This replaces the first cut at this series: https://www.redhat.com/archives/libvir-list/2010-April/msg01341.html Changes since v1: squash the original 1/5 and 2/5 into one patch test every stage of the series on a cross-compile to mingw add new 5/5, and adjust to recent syntax checks available in today's gnulib [PATCHv2 1/5] build: rely on gnulib's pthread module [PATCHv2 2/5] build: use gnulib's uname [PATCHv2 3/5] build: use gnulib's sys/wait.h [PATCHv2 4/5] build: drop more redundant configure checks [PATCHv2 5/5] build: update gnulib Because of the new patch, I'll wait for a re-ACK before pushing; but 1 through 4 are pretty much unchanged from their original ACK. .gnulib | 2 +- .x-sc_prohibit_always_true_header_tests | 4 ++++ bootstrap.conf | 3 +++ configure.ac | 22 ++++------------------ src/libvirt.c | 4 +--- src/network/bridge_driver.c | 1 - src/nodeinfo.c | 12 ++---------- src/openvz/openvz_conf.c | 2 +- src/openvz/openvz_driver.c | 2 +- src/phyp/phyp_driver.c | 1 - src/qemu/qemu_driver.c | 1 - src/remote/remote_driver.c | 5 +---- src/storage/storage_backend.c | 4 +--- src/uml/uml_driver.c | 1 - src/util/ebtables.c | 7 ++----- src/util/hooks.c | 4 +--- src/util/iptables.c | 7 ++----- src/util/processinfo.c | 6 ++---- src/util/util.c | 4 +--- 19 files changed, 27 insertions(+), 65 deletions(-)
Gnulib can guarantee that pthread.h exists, but for now, it is a dummy header with no support for most pthread_* functions. Modify our use of pthread to use function checks, rather than header checks, to determine how much pthread support is present. * bootstrap.conf (gnulib_modules): Add pthread. * configure.ac: Drop all pthread.h checks. Optimize function checks. Add check for pthread functions. * src/Makefile.am (libvirt_lxc_LDADD): Ensure proper link. * src/remote/remote_driver.c (remoteIOEventLoop): Depend on pthread_sigmask, now that gnulib guarantees pthread.h. * src/util/util.c (virFork): Likewise. * src/util/threads.c (threads-pthread.c): Depend on pthread_mutexattr_init, as a witness of full pthread support. * src/util/threads.h (threads-pthread.h): Likewise. --- bootstrap.conf | 1 + configure.ac | 21 +++++++++++---------- src/Makefile.am | 3 ++- src/remote/remote_driver.c | 6 +++--- src/util/threads.c | 4 ++-- src/util/threads.h | 4 ++-- src/util/util.c | 10 +++++----- 7 files changed, 26 insertions(+), 23 deletions(-) diff --git a/bootstrap.conf b/bootstrap.conf index 785489b..da7cc9c 100644 --- a/bootstrap.conf +++ b/bootstrap.conf @@ -43,6 +43,7 @@ perror physmem poll posix-shell +pthread recv random_r send diff --git a/configure.ac b/configure.ac index 5d68dcc..93eb654 100644 --- a/configure.ac +++ b/configure.ac @@ -106,10 +106,19 @@ dnl Use --disable-largefile if you don't want this.

Changes since v1: squash the original 1/5 and 2/5 into one patch test every stage of the series on a cross-compile to mingw add new 5/5, and adjust to recent syntax checks available in today's gnulib
[PATCHv2 1/5] build: rely on gnulib's pthread module [PATCHv2 2/5] build: use gnulib's uname [PATCHv2 3/5] build: use gnulib's sys/wait.h [PATCHv2 4/5] build: drop more redundant configure checks [PATCHv2 5/5] build: update gnulib
Because of the new patch, I'll wait for a re-ACK before pushing; but 1 through 4 are pretty much unchanged from their original ACK.

Thanks for the review, and for teaching me some patience while waiting for it :) Now pushed. -- Eric Blake eblake@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
