Re: [libvirt] [PATCHv2] build: fix build on platforms without ptsname_r

MacOS lacks ptsname_r, and gnulib doesn't (yet) provide it. But we can avoid it altogether, by using gnulib openpty() instead. Note that we do _not_ want the pt_chown module; all systems that we currently port to can either properly do openpty() and/or grantpt(), or lack ptys altogether; we are not porting to any system that requires us to deal with the hassle of installing a setuid pt_chown helper just to satisfy gnulib's ability to provide openpty() on even more platforms. * .gnulib: Update to latest, for openpty fixes * bootstrap.conf (gnulib_modules): Add openpty, ttyname_r. (gnulib_tool_option_extras): Exclude pt_chown module. * src/util/util.c (virFileOpenTty): Rewrite in terms of openpty and ttyname_r. * src/util/util.h (virFileOpenTtyAt): Delete dead prototype. --- Alas, this is just complicated enough that I don't feel comfortable pushing it under the build-breaker rule, even though I have verified that it fixes builds on both FreeBSD and Cygwin, as well as still behaves correctly with LXC containers on Linux. Anyone willing to give this a review before 0.9.7 gets released? .gnulib | 2 +- bootstrap.conf | 3 ++ src/util/util.c | 73 ++++++++++++++++++++++++++++++++++++++++-------------- src/util/util.h | 5 ---- 4 files changed, 58 insertions(+), 25 deletions(-)
