IRC, freenode, #hurd, 2011-04-02 <youpi> the sudo bug is select() not being able to get interrupted by signals # IRC, freenode, #hurd, 2013-01-05 In context of [[alarm_setitimer]]. <youpi> it's a know issue in select <youpi> it's not interruptible by a SIGALRM for instance <youpi> which is what ntpdate uses <youpi> when __io_select is used, it *is* interruptible <youpi> but when __mach_msg is used, it is *not* interruptible <youpi> it happens that by luck, ntpdate uses just one fd, and thus it's __io_select which is used, and thus it gets an interruption after 1s (instead of after 60s, the timeout) <youpi> with braunr's patch, it's __mach_msg which is used to wait, and thus the interruption doesn't happen, and we have to wait 60s, the timeout... <youpi> so braunr's patch is still correct, it's the __mach_msg call which we do need to make interruptible (it was already on the todolist) Proposed patch: [[!message-id "20130105162817.GW5965@type.youpi.perso.aquilenet.fr"]]. ## IRC, freenode, #hurd, 2013-01-15 <_d3f> Hello, any one else having problems with git? <braunr> _d3f: yes <braunr> _d3f: it will be fixed in the next glibc release <_d3f> oh thx. what was the problem? <braunr> http://lists.gnu.org/archive/html/bug-hurd/2013-01/msg00005.html <WhiteKIBA> exactly this problem is preventing us building glibc <braunr> it's indeed very annoying <braunr> and this fix will probably have a visible and positive effect on other issues <_d3f> let's hope so. <braunr> well, i'm already using it and see the difference --- See also [[select]] and [[select_bogus_fd]].
