| Description: | An additional "alt" argument was introduced for build_user() in chan_sip.c rev 104095, and exit condition in for() loop was modified. But I read it and read it again, and I can't see any difference between former for (; v; v = v->next) and new for (; v || ((v = alt) && !(alt=NULL)); v = v->next) In both cases, the exit condition can be summarized to "v is not NULL". But I think that former expression is much more readable. | ||
| Comments: | By: Frederic LE FOLL (flefoll) 2008-03-03 05:24:15.000-0600 OOOPS ! I didn't catch the embedded double affectation "v=alt" and "alt=NULL". Shame on me... The first patch I proposed is totally inadequate. I propose another one that just inserts a comment for people like me... Anyway, the best thing that can happen to this issue is to be closed now :-) By: Digium Subversion (svnbot) 2008-03-03 09:11:51.000-0600 Repository: asterisk Revision: 105557 U branches/1.4/channels/chan_sip.c ------------------------------------------------------------------------ r105557 | file | 2008-03-03 09:11:48 -0600 (Mon, 03 Mar 2008) | 6 lines Add a comment to describe some logic.

Instead, use a thread condition so that the thread properly goes to sleep and does not wake up until a channel is put into autoservice. This actually fixes an interesting bug, as well. If the autoservice thread is already running (almost always is the case), then when the thread goes from having 0 channels to have 1 channel to autoservice, that channel would have to wait for up to 1/2 of a second to have the first frame read from it. 2) Fix up the code in ast_waitfor_nandfds() for when it gets called with no channels and no fds to poll() on, such as was the case with the previous code for the autoservice thread. In this case, the code would call alloca(0), and pass the result as the first argument to poll(). In this case, the 2nd argument to poll() specified that there were no fds, so this invalid pointer shouldn't actually get dereferenced, but, this code makes it explicit and ensures the pointers are NULL unless we have valid data to put there.
