virNodeInfo nodeinfo;
Use gnulib, starting with its physmem and getaddrinfo modules. New files go into these directories: gnulib/lib gnulib/m4 gnulib/tests * bootstrap: A wrapper around gnulib-tool. * configure.in: Invoke gl_EARLY and gl_INIT, being careful to put gl_EARLY before any macro that uses AC_COMPILE_IFELSE. (AC_OUTPUT): Add lib/Makefile and gl-tests/Makefile. Remove m4/Makefile. * Makefile.am (SUBDIRS): Add gnulib/lib and remove m4. Add gnulib/tests early enough that those tests run before any libvirt unit tests. * m4/Makefile.am: Remove file. Not needed. * src/Makefile.am (INCLUDES): Add -I$(top_srcdir)/gnulib/lib -I../gnulib/lib. (LDADDS, libvirt_la_LIBADD): Add ../gnulib/lib/libgnu.la. * src/nodeinfo.c: Include "physmem.h". * qemud/qemud.c, src/remote_internal.c: Include "getaddrinfo.h". (MEMINFO_PATH, linuxNodeInfoMemPopulate): Remove definitions. (virNodeInfoPopulate): Use physmem_total, not linuxNodeInfoMemPopulate. * tests/Makefile.am (INCLUDES): Add -I$(top_srcdir)/gnulib/lib -I../gnulib/lib. (LDADDS): Add ../gnulib/lib/libgnu.la. * qemud/Makefile.am (libvirtd_LDADD): Add ../gnulib/lib/libgnu.la. * tests/nodeinfotest.c (linuxTestCompareFiles): No longer read total memory from a file. Update expected output not to include "Memory: NNNN" * tests/nodeinfodata/linux-nodeinfo-1.txt: * tests/nodeinfodata/linux-nodeinfo-2.txt: * tests/nodeinfodata/linux-nodeinfo-3.txt: * tests/nodeinfodata/linux-nodeinfo-4.txt: * tests/nodeinfodata/linux-nodeinfo-5.txt: * tests/nodeinfodata/linux-nodeinfo-6.txt: * src/test.c [WITH_TEST]: Remove definition of _GNU_SOURCE that would conflict with the one now in "config.h". * autogen.sh: Add -I gnulib/m4. * src/conf.c, src/sexpr.c: Don't define _GNU_SOURCE. Instead, include "config.h". * qemud/qemud.c: Remove definition of _GNU_SOURCE. * src/openvz_driver.c: Likewise. * src/qemu_driver.c: Likewise. * src/remote_internal.c: Likewise. * configure.in: Use AC_CONFIG_AUX_DIR(build-aux), so that a bunch of gettextize-generated files go into build-aux/, rather than in the top-level directory. * .cvsignore: Adjust. * build-aux/.cvsignore: New file.

tests: simplify common setup A few of the tests were missing basic sanity checks, while most of them were doing copy-and-paste initialization (in fact, some of them pasted the argc > 1 check more than once!). It's much nicer to do things in one common place, and minimizes the size of the next patch that fixes getcwd usage. * tests/testutils.h (EXIT_AM_HARDFAIL): New define. (progname, abs_srcdir): Define for all tests. (VIRT_TEST_MAIN): Change callback signature. * tests/testutils.c (virtTestMain): Do more common init. * tests/commandtest.c (mymain): Simplify. * tests/cputest.c (mymain): Likewise. * tests/esxutilstest.c (mymain): Likewise. * tests/eventtest.c (mymain): Likewise. * tests/hashtest.c (mymain): Likewise. * tests/networkxml2xmltest.c (mymain): Likewise. * tests/nodedevxml2xmltest.c (myname): Likewise. * tests/nodeinfotest.c (mymain): Likewise. * tests/nwfilterxml2xmltest.c (mymain): Likewise. * tests/qemuargv2xmltest.c (mymain): Likewise. * tests/qemuhelptest.c (mymain): Likewise. * tests/qemuxml2argvtest.c (mymain): Likewise. * tests/qemuxml2xmltest.c (mymain): Likewise. * tests/qparamtest.c (mymain): Likewise. * tests/sexpr2xmltest.c (mymain): Likewise. * tests/sockettest.c (mymain): Likewise. * tests/statstest.c (mymain): Likewise. * tests/storagepoolxml2xmltest.c (mymain): Likewise. * tests/storagevolxml2xmltest.c (mymain): Likewise. * tests/virbuftest.c (mymain): Likewise. * tests/virshtest.c (mymain): Likewise. * tests/vmx2xmltest.c (mymain): Likewise. * tests/xencapstest.c (mymain): Likewise. * tests/xmconfigtest.c (mymain): Likewise. * tests/xml2sexprtest.c (mymain): Likewise. * tests/xml2vmxtest.c (mymain): Likewise.
