Russell Bryant	7a007060bd	Commit a fix for some memory access errors pointed out by the valgrind2.txt output on issue #11698. The issue here is that it is possible for an instance of a translator to get destroyed while the frame allocated as a part of the translator is still being processed. Specifically, this is possible anywhere between a call to ast_read() and ast_frame_free(), which is _a lot_ of places in the code. The reason this happens is that the channel might get masqueraded during this time. During a masquerade, existing translation paths get destroyed. So, this patch fixes the issue in an API and ABI compatible way. (This one is for you, paravoid!) It changes an int in ast_frame to be used as flag bits. The 1 bit is still used to indicate that the frame contains timing information. Also, a second flag has been added to indicate that the frame came from a translator. When a frame with this flag gets released and has this flag, a function is called in translate.c to let it know that this frame is doing being processed. At this point, the flag gets cleared. Also, if the translator was requested to be destroyed while its internal frame still had this flag set, its destruction has been deffered until it finds out that the frame is no longer being processed. Admittedly, this feels like a hack. But, it does fix the issue, and I was not able to think of a better solution ... git-svn-id: https://origsvn.digium.com/svn/asterisk/branches/1.4@98943 65c4cc65-6c06-0410-ace0-fbb531ad65f3	18 years ago

Kevin P. Fleming	1209386fe7	emit a warning message when we drop a G.729B CNG frame destined for the transcoder git-svn-id: https://origsvn.digium.com/svn/asterisk/branches/1.4@92656 65c4cc65-6c06-0410-ace0-fbb531ad65f3	18 years ago
Kevin P. Fleming	bcedcf5f8a	even though Asterisk explicitly requests that endpoints using G.729 do not use Annex B (silence detection and comfort noise generation) some do anyway; the transcoder card interface does not currently work properly with CNG frames, so trim off the CNG before sending the data git-svn-id: https://origsvn.digium.com/svn/asterisk/branches/1.4@91870 65c4cc65-6c06-0410-ace0-fbb531ad65f3	18 years ago

Jason Parker	9803b9a357	Make codec_zap and chan_zap also depend on zaptel. This fixes an issue (8727) with zaptel being in a different directory, using --with-zaptel. git-svn-id: https://origsvn.digium.com/svn/asterisk/branches/1.4@49705 65c4cc65-6c06-0410-ace0-fbb531ad65f3	19 years ago
Kevin P. Fleming	f195c5d622	check specifically for VLDTMF and transcoding support in the system's Zaptel installation, and make only the modules that need those features dependent on them (this will allow building the other Zaptel-using parts of Asterisk against older versions of Zaptel or those on other platforms that haven't caught up yet to the Linux version) git-svn-id: https://origsvn.digium.com/svn/asterisk/branches/1.4@49102 65c4cc65-6c06-0410-ace0-fbb531ad65f3	19 years ago

Kevin P. Fleming	0a27d8bfe5	merge new_loader_completion branch, including (at least): - restructured build tree and makefiles to eliminate recursion problems - support for embedded modules - support for static builds - simpler cross-compilation support - simpler module/loader interface (no exported symbols) git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@40722 65c4cc65-6c06-0410-ace0-fbb531ad65f3	19 years ago

Kevin P. Fleming	e61d3d91f3	The Eurostar Commit! (it's amazing how much work you can get done on a 150 minute train ride from Paris to London <G>) support the new location for zaptel.h and tonezone.h use the dependency information output by menuselect to build Makefile rules for each module for header files and libraries combine the common rules into a top-level Makefile.rules file remove all (now) unnecessary stuff from subdir Makefiles change translator API so that the newpvt() callback returns an int instead of a pointer (it no longer allocates memory) alphabetize --with-<foo> options in configure script enhance Net-SNMP support in configure script to provide a --with-netsnmp option fix support for --with-pq so that if pg-config is not found when --with-pq is specified, an error will be generated add 'optional package' usage to modules now that menuselect can output it allow res_snmp to build by default, since the new loader changes coming soon will solve the function naming problem (and users can disable it via menuselect anyway) git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@35832 65c4cc65-6c06-0410-ace0-fbb531ad65f3	20 years ago
