Recently, I heard of two tricky portability problems in libvirt that are easy to solve with gnulib. Of course, gnulib provides a lot more, and is not exactly lightweight if you count "lines of code imported", but once the framework (this patch) is installed, adding an additional module is as easy as adding the module name to a list. Keep in mind that what matters with a portability library is that it stay out of your way -- and of course do its job well. To that end, gnulib has many per-module unit tests. Since a large part of its job is portability, and insulating your code from bugs (be they bugs in the very latest glibc printf functions, or in the regexp library, or just protection against that crufty old SunOS4 free function that can't deal with NULL), it provides a mechanism to let you conveniently include its self tests in your own package and run them when users run "make check" for your project. This is pretty important, so that if someone builds your package on an unusual or poorly-configured system, often the gnulib tests will fail right away, and that will save you the trouble of digging through your own package's code. For those of you who don't know, gnulib is the GNU Portability Library. http://www.gnu.org/software/gnulib/ and it is used in many widely-used packages: http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob;f=users.txt;hb=HEAD Of course, there's no guarantee that the code is bug-free, but in practice, the few bugs being fixed these days involve portability to relatively unusual systems. With so many widely-used packages using gnulib, you can imagine that if there are bugs, they will be encountered, reported, and fixed pretty quickly. One of the biggest advantages of using gnulib is that you can add new modules and get all the benefits with *no* additional tweaking. I.e., you don't have to write .m4 macros, modify configure.ac or any Makefile.am. It just works. If something doesn't, or if the documentation is unclear, you can report it to bug-gnulib(a)gnu.org and usually get a fix or an explanation pretty quickly. ---------- Enough of the hype. The first portability problem was to determine the total physical memory available on the current system. Currently the code works only on Linux-like systems that have /proc/meminfo of an expected form. However, the gnulib physmem module handles 13 distinct types of systems and is well tested: http://www.gnu.org/software/gnulib/MODULES.html#module=physmem The second portability problem was to find a robust and LGPL-compatible getaddrinfo function to be used on systems lacking it. Here's the gnulib module: http://www.gnu.org/software/gnulib/MODULES.html#module=getaddrinfo Once the few gnulib hooks are in your configure.ac and Makefile.am files, there is very little extra work required to use the new functions. In the case of physmem, just use the function and include "physmem.h". For getaddrinfo, merely include "getaddrinfo.h" from the two files that use the function. This change brings in a lot of code, but many of the lib/.[ch] files are used only on systems that lack some required functionality. For example, the getaddrinfo.c file isn't even compiled when it's not needed. In the patch below, I've included a new script called bootstrap. It is a wrapper around gnulib-tool that pulls into libvirt the files selected by the (currently two) modules in use. Those new files go in three places: m4/*.m4 lib/*.[ch] and a few template .h.in files gl-tests/ for unit test C programs and Bourne shell scripts However, note that gettextize and libtoolize (run by autogen.sh) also deposit many *.m4 files in m4. I compared and found that 8 of the files that are already pulled in by the *ize programs are also pulled in (potentially newer versions) from gnulib. But currently, using gettext-0.16.1 or gettext-0.17, there is no difference in any of the overlapping files. Re Licenses: the two modules (and all of their dependent modules) are LGPL-compatible. This is enforced by running gnulib-tool with the --lgpl option. If you were to request a module with an incompatible license (say GPL or LGPLv3), it would fail. ---------------------- Here's the patch that shows what existing parts of libvirt have to be modified to use these two new modules. To try it out, just apply the patch and then run this: ./autogen.sh && ./bootstrap && make && make check Running bootstrap creates the new lib/ and gl-tests/ directories. Personally, I prefer not to add generated files to version control systems, because it can lead to problems with version skew if all developers don't use the same releases of the tools that do the generating. Perhaps more importantly, when there are massive diffs in the generated files, that can obscure real changes in non-generated parts of the code. That already happens to me whenever the .po files change. But if people prefer to add all of these imported files to CVS, just say the word and I'll prepare the patch. If so, do you guys want the gettextize- and libtoolize-added files to be version-controlled, now, too? Use gnulib, starting with physmem and getaddrinfo modules. * 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.
