* libX: add new release / version info tagsAaron Conole2017-01-181-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit uses the $PACKAGE_VERSION automake variable to construct a release and version info combination which sets the library name to be: libfoo-$(OVS_MAJOR_VERSION).so.$(OVS_MINOR_VERSION).0.$(OVS_MICRO_VERSION) where formerly, it was always: libfoo.so.1.0.0 This allows releases of Open vSwitch libraries to reflect which specific versions they came with, and sets up a psuedo ABI-versioning scheme. In this fashion, future releases of Open vSwitch could be installed alongside older releases, allowing 3rd party utilities linked against previous versions to continue to function. ex: $ ldd /path/to/utility linux-vdso.so.1 (0x00007ffe92cf6000) libopenvswitch-2.so.6 => /lib64/libopenvswitch-2.so.6 (0x00007f733b7a3000) libssl.so.10 => /lib64/libssl.so.10 (0x00007f733b530000) ...

* python: Fix xmlrpclib imports.Russell Bryant2016-01-201-0/+6
| | | | | | | | | | | | | | Fix imports of xmlrpclib to be compatible with Python 3. Python 2 had xmlrpclib (client) and SimpleXMLRPCServer (server). In Python 3, these have been renamed to xmlrpc.client and xmlrpc.server. The solution implemented here is to use the six library. It may seem excessive for this particular issue, but the six library provides helpers for Python 2 and 3 compatibility for many different issues. This is just the first of many uses of the six library. Signed-off-by: Russell Bryant <russell@ovn.org> Acked-by: Ben Pfaff <blp@ovn.org>

| | | | | | | | | | | | | | | | | | | Add configuration option for enabling or disabling linking with libcap-ng. Since capabilities are a security feature, the libcapng option is handled as follows: - no option: use libcapng if it's present --disable-libcapng: do not use libcapng --enable-libcapng: do use libcapng and fail configuration if it's missing On Linux, not linking with libcapng makes all OVS daemons fail when --user option is specified.

* configure: Omit -O2 from CFLAGS when configuring with --enable-coverage.Ben Pfaff2015-01-121-2/+14
| | | | | | | | | | | | | | CFLAGS follows OVS_CFLAGS in the compiler command line, and should, so that the user can override any automatically determined compiler options. That means that the -O0 that the code here added to OVS_CFLAGS didn't really have any effect since CFLAGS by default includes "-O2". However, we do really want to disable optimizations (because the coverage reports are hard to interpret with optimizations), so this commit changes the configure script to edit out -O2 from CFLAGS, leaving any other default or user-specified options.

* cccl: Ability to enable compiler optimization.Gurucharan Shetty2014-09-041-0/+11
| | | | | | | | | | | | | | | | | | | | MSVC has a '-O2' compiler optimization flag which makes code run fast and is the recommended option for released code. For e.g., running "./tests/ovstest.exe test-cmap benchmark 1000000 3 1" shows a 3x improvement for some cmap micro-benchmarks. In the Visual Studio world, there is a concept of "release" build (fast code, harder to debug) and a "debug" build (easier to debug). The IDE provides this option and the IDE users expect something similar for command line build. So this commit, introduces a "--with-debug" configure option for Windows and does not use '-O2' as a compiler option when specified. This can be extended further if there are more compiler options that distinguish a "release" build vs "debug" build.

* build: Allow building with autoconf 2.63Thomas Graf2014-06-272-0/+34
| | | | | | | | | | | | | | | | | | | | Reduces the dependency on autoconf from 2.64 to 2.63 to ease building on older platforms. There is only a few macros missing and they can be provided easily. A handful of tests needed modification. The difference in quoting behaviour between 2.63 and later require the m4_define() to be manually unfolded. The Debian control file is left untouched on purpose. The decision whether to adjust the dependency is left to the respective maintainers. Tested with autoconf 2.63 and 2.69.

* openvswitch: Use libtool and allow building shared libsHelmut Schaa2013-12-171-0/+5
| | | | | | | | | | | | | | | | | | | | | | Currently openvswitch builds all libraries static only. However, libopenvswitch is linked into nearly all openvswitch executables making it hardly possible to run openvswitch on embedded devices (for example running OpenWrt). Convert openvswitch to use libtool for building its internal libs. This allows "--enable-shared" and "--enable-static" as configure arguments. Default is "--disable-shared" thus keeping the current behavior with the only change that static libs are installed by "make install". Since the openvswitch library interfaces are internal and thus not stable (yet) encode the openvswitch version into the library name: libopenvswitch-2.0.90.so Binary size is reduced to around 1/3 when using shared libs.

GCC and C11 have two different forms of per-thread data that are generally faster than the POSIX API, where they are available.
