<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: id:"20130105162817.GW5965@type.youpi.perso.aquilenet.fr".

<_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
