Re: Pyrex experts? Looking to expose settimeofday() and RTC_SET_TIME ioctl()

The python part is mostly done, but the fun part is that we're trying to set the clock (both system clock and rtc) based on network messages. The general approach in our initramfs when we need some specific calls to potent magic hidden (as we often do in our voodoo initramfsen) is to unleash The Power of Pyrex. So that's what I plan to do. I wouldn't have thought pyrex is necessary. I suggest using fnctl.ioctl() for RTC_SET_TIME, and ctypes for settimeofday().

Our chvt() is in pyrex, and all it does is call ioctl() on /dev/console. If there's a better way to call ioctl() then we can get rid of pyrex in our initramfs completely. In the meantime, I am following the approach already in use in our initramfs, and Hal Murray's posted in private a very nice pyrex wrapper around those two that I plan to test/merge/use today. cheers, m -- martin.langh...@gmail.com mar...@laptop.org -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

If there's a better way to call ioctl() then we can get rid of pyrex in our initramfs completely. It's not quite that simple, see e.g. pyfb/pyvt. But yes, I believe that most or all of the stuff could be rewritten using ctypes and fnctl without much effort. The code was written before ctypes existed.

I don't have any ctypes experience, but from what I read, it looks like it really would be trivial. Hal, would you be interested in trying this alternative approach for the 2 new bits that we need? :) Daniel ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

What impact would it have in our initramfs? Does it expect header files to do its job? Does it require new modules / so files in the initramfs? (the ctypes dir in f11 weighs in at 164KB, it could however depend on other stuff...) Any any case, if we're forced to keep using Pyrex, let's use Pyrex, instead of a dozen things. We already have a bazillion languages, libraries and toolkits. I definitely don't want to add to the burden. cheers, m -- martin.langh...@gmail.com mar...@laptop.org -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
