2005-04-26[PATCH] install udevinfo in /usr/binkay.sievers@vrfy.org
Here we rename the former tiny $(HELPER) to $(INFO) cause it's no longer only a helper :) And install it in /usr/bin instead of /sbin cause any user may want to call it and we don't need it on startup.

Hm, looks like we do not need the %{lsb} and USE_LSB logic at all, anymore. Here is the patch, updated, removing both completely.
2005-04-26[PATCH] add udevstart program based on a old patch from Harald Hoyer ↵greg@kroah.com

So here is the next try :) hpa, for good reason, didn't like my changes to klibc. He will dump signal() completely from klibc instead, so here we switch to sigaction() and keep udevd working with klibc.
2005-04-26[PATCH] make logging a config optionazarah@nosferatu.za.org
Once again, patch to make logging a config option. Reason for this (since you asked for it): - In our setup it is easy (although still annoying) .. just edit the ebuild, add logging support (or remove it) and rebuild. For say a binary distro, having the logging is useful for debugging some times, but its more a once of, or rare thing, as you do not add or change config files every day. Sure, we can have logging by default, but many do not want ~300 lines of extra debugging in their logs is not pleasant, and they will complain. Rebuilding the package for that binary package (given the users it is targeted to) is usually not within most users grasp.

Please recheck it. Test script is switched to work on subsystem 'test' to let udev ignore it.
2005-04-26[PATCH] udevd - kill the lockfilekay.sievers@vrfy.org
2005-04-26[PATCH] udevd - switch socket path to abstract namespacekay.sievers@vrfy.org
As Chris Friesen <chris_friesen@sympatico.ca> suggested, here we switch the unix domains socket path to abstract namespace and get rid of the socket file in the filesystem. Hey, this was new to me today. So here a few words: Linux supports a abstract namespace for sockets. We don't need a physical file on the filesystem but only a unique string magically starting with the '\0' character. strace with real file: connect(3, {sa_family=AF_UNIX, path="/udev/.udevd.sock"}, 110) strace with abstract namespace: connect(3, {sa_family=AF_UNIX, path=@udevd}, 110)

Next cleaned up version. Hey, nobody wants to try it :) Works for me, It's funny if I connect/disconnect my 4in1-usb-flash-reader every two seconds. The 2.6 usb rocks! I can connect/diconnect a hub with 3 devices plugged in every second and don't run into any problem but a _very_ big udevd queue.
2005-04-26[PATCH] udevd - next round of fixeskay.sievers@vrfy.org
Here is the next round. We have three queues now. All incoming messages are queued in msg_list and if nothing is missing we move it to the running_list and exec in the background. If the exec comes back, it removes the message from the running_list and frees the message. Before we exec, we check the running_list if there is a udev running on the same device path. If yes, we move the message to the delay_list. If the former exec comes back, we move the message to the running_list and exec it. The very first event is delayed now to catch possible earlier sequences, every following event is executed without delay if no sequence is missing. The daemon doesn't exit by itself any longer, cause we don't want to delay every first exec. I've put a $(PWD) for now in the Makefile for testing this beast. Only the local binaries are executed, not the /sbin/udev. We can change it if we are ready for real testing. And SIGKILL can't be cought, so I removed it from the handler :) 06:58:36 sig_handler: caught signal 15 06:58:36 main: using ipc queue 0x2d548 06:58:37 message is still in the ipc queue, starting

2005-04-26[PATCH] udevd - cleanup and better timeout handlingkay.sievers@vrfy.org
Here is the next revision for udevd: o Small cleanups all over the place. o Swich to the usual linked list format "list.h". o Better timeout handling. We store a timestamp in in every queued event, so we don't wait longer than the timeout specified, if the hole in the list is not shrinking. o ignore udevd target if klibc is used
