[libvirt] Minor compile failure on OSX for libvirt 2.0.0
by Justin Clift 20 Jul '16

20 Jul '16

Hi all, There's a minor compile failure on OSX with libvirt 2.0.0: CC util/libvirt_util_la-virtime.lo CC util/libvirt_util_la-virtpm.lo util/virsystemd.c:524:26: error: use of undeclared identifier 'MSG_NOSIGNAL' if (sendmsg(fd, &mh, MSG_NOSIGNAL) < 0) ^ 1 error generated. make[3]: *** [util/libvirt_util_la-virsystemd.lo] Error 1 make[3]: *** Waiting for unfinished jobs.... Seems solvable by adding a stub declaration for MSG_NOSIGNAL on systems that don't implement it. An initial patch with the declaration, developed by Tomasz Pajor (CC'd), is below: --- src/util/virsystemd.h.orig 2016-07-03 21:40:12.000000000 +0200 +++ src/util/virsystemd.h 2016-07-03 21:37:53.000000000 +0200 @@ -57,3 +57,7 @@ char *virSystemdGetMachineNameByPID(pid_t pid); #endif /* __VIR_SYSTEMD_H__ */ + +#ifndef MSG_NOSIGNAL +#define MSG_NOSIGNAL 0x0 //Don't request NOSIGNAL on systems where this is not implemented. +#endif It's outside the #endif for __VIR_SYSTEMD_H___ though, so I'm kind of thinking it would need to be move inside the guard (which also compiles ok), or is there a better place/file for it instead? :) Regards and best wishes, Justin Clift -- "My grandfather once told me that there are two kinds of people: those who work and those who take the credit.

[libvirt] [PATCH 0/2] Need to set booleans in right place for hotplug cleanup

After pushing and working on the next set of changes, I realized that the setting of some booleans needed to be inside an if condition <sigh>.

[libvirt] [PATCHv2 0/3] Speed up hvsupport.pl
by Ján Tomko 20 Jul '16

20 Jul '16

This reduces the script execution time from 14.7s to 60 ms. Since this was by far the longest taking target from the docs/ directory and make does not parallelize across Makefiles, the savings are similar for a complete build from a fresh git checkout. The second patch shaves off 8.2s, the third 6.4s and the last one shaves off half of the remaining time. v2: * renamed parseAPIXML to getAPIFilenames * documented getAPIFilenames * comment in apibuild.py above the line that generates the data consumed by hvsupport.pl * more verbose commit messages Ján Tomko (3): hvsupport: use a regex instead of XML::XPath hvsupport: construct the group regex upfront hvsupport: skip non-matching lines early bootstrap.conf | 1 - docs/apibuild.py | 1 + docs/hvsupport.pl | 69 +++++++++++++++++++++++++++++++++++++------------------ 3 files changed, 48 insertions(+), 23 deletions(-) -- 2.7.3
