[Freeswitch-dev] DSO library management issues
by Roman Shaposhnik 01 Oct '06

01 Oct '06

Hi Guys! I'm getting pretty close to having FreeSwitch up and running on a SPARC Solaris Niagara box (yeah -- that's the one with 8 physical cores and 32 threads per CPU) which is a good news. The bad news (at least from my POV) is that I think I've stumbled upon a particular problem in how FreeSwitch gets built and packaged for which I don't really have a good solution. So, in order for me to move forward I have to make sure that you guys also view this as an issue and that you'd be willing to address it. Here's the deal -- its no secret that FreeSwitch depends on DSOs a *LOT* (in fact, the core of FreeSwitch itself is a DSO library with a simple wrapper bin/freeswitch around it). In general I would divide these DSOs into 3 broad categories: 1. Plugin/modules (including CORE) These guys posses no problem whatsoever -- they get developed within the FreeSwitch SVN repository, they DO NOT get distributed outside of FreeSwitch. They also get built as part of building FreeSwitch. Always. The only trouble with them is that sometimes they depend on functionality available only from external libraries. And that leads us to the following 2 categories: 2. Well-known external DSO libraries These are the things you would expect to see on a reasonably well configured Linux system these days. Things like /usr/lib/libsqlite3.so or /usr/lib/libapr.so.0. Things which get developed elsewhere, have their dedicated maintainers and packagers. And which are relatively easy to find in .RPMs or .DEBs. 3. DSO libraries originating from the FreeSwitch project itself. Now in this category I don't want to discriminate between something that Anthony has written (i.e. libteletone) or something that just got sucked into FreeSwitch for a lack of a better home (i.e. lib/codec/g726). All of these things Now, why am I telling you all this ? :-) Well, simply because during my Solaris "porting" effort I've really convinced myself that we have to have a much better plan for #2 and #3 w.r.t. building and packaging than what we have in FreeSwitch now. And here's why: 1. For the #2 I really don't want to sit through the endless stream of ./configure ; make ; make install if I already have these libraries on my system. What I want instead is a detection mechanism (or --with-<package name>= option for a configure script) that would also warn me about the version FreeSwitch developers deem to be appropriate for each of the packages. 2. As for the #3... my take on it is that we shouldn't really have #3 in FreeSwitch at all. Every single library from that category should either be moved to #1 or to #2. If it ends up being in #2 than it has to be moved to a separate SVN repo. So consider all of the above as a preliminary request for opinions and lets hope to make FreeSwitch really portable and highly configurable at the building and packaging level! Thanks, Roman.

Re: [Freeswitch-dev] DSO library management issues
by Anthony Minessale 01 Oct '06

There are a few good explanations (I hope). I have chosesn to build all of the code used in the program for a few reasons: 1) To ensure proper configuration and versioning. a) We have no control over what options the default system libs were built with (thread saftey options etc). b) As a side-effect of our extensive push on our dependancies, we often need the code to be modified to work properly due to necessary modifications or bugfixes that only exist in our private tarball while we wait for a new version to be released. c) Most distros do not provide cutting edge releases of libraries which be necessary due to results from sub-reason (b) 2) To create a atonomous environment. a) The defualt install prefix is /usr/local/freeswitch all of the depends are installed in this dir so you can subsequently tar up that directory and move it to another machine without installing it again. b) Some systems have slightly different versions of the same libraries that do not co-exist well we never need to look outside of our own lib dir for these libraries. I am fairly concerned with making huge initiatives in the build process during a time where I am still coding 12 hours a day on the core but I am open to improvement as long as the tangent does not impeed my development effort. Imagine if someone wanted to install superior scafolding while the guy is on top of it building the house still. Once development shifts to higher level stuff my concerns will most likely subside. One bright note is if you dont watch during the endless stream of ./configure make ; make install, it goes faster (a watched pot never boils) =D And that only happens the first time, subsequent builds go much faster. I am truely anxious to see what happens on this super sun box and I'd like to thank you for your efforts and your valuable time I really appriciate your help.

[Freeswitch-dev] Solaris build/DTrace status
by Roman Shaposhnick 27 Sep '06

27 Sep '06

Hi Guys! First of all after poking around freeswitch source code a bit I've decided that personally I would really like to apply DTrace to it to see what's going on w.r.t. threading. Hence I really need to make sure that it builds on Solaris10/SPARC. Because of that I decided to put other things (like PerfAnalyzing it on Linux on a backburner) and focus on at least building it on Solaris. I think I'm making some progress there, but it also seems to me that your build process might need a bit of a cleanup. Little things like specifying #!/bin/sh but actually expecting bash. Little things -- but they do add up. Thanks, Roman. P.S. And if anybody has any tips for me w.r.t. SPARC/Solaris build I'd be more than happy to hear them.

[Freeswitch-dev] mod_cepstral and session.hangup() in javascript
by Nikolay Kolev 21 Sep '06

21 Sep '06

Hi all! On September 9 there was a change in mod_cepstral to switch to dynamic buffers, but at the same time the buffer size got reduced. As a result, the module broke and in some situations it cut off sounds, crapping out totally the TTS. I restore the buffer size to the old value (1024 * 256) and it works perfectly again! Can somebody patch the trunk as most probably I don't have the rights to do so. Also, some of the commits to the core today fixed the problem with session.hangup() in javascript not closing the session. Now, it works properly! Thanks, guys! Nikolay Kolev kolev @ #freenode

[Freeswitch-dev] Error: "Cannot Initialize [Cannot Open XML Root!]
by Michael Collins 20 Sep '06

20 Sep '06

Guys, Has anyone run into this error before? I'm running the snapshot, downloaded on Sunday night. The only compilation issue that I could see did happen on the xmlrpc-c-1.03.14 install: GNUmakefile:8: /usr/src/snapshot_freeswitch/libs/xmlrpc-c-1.03.14/Makefile.config: No such file or directory However, xmlrpc does complete the make & make install processes without any other complaints. I searched and google'd this error but I came up empty. Thanks for your help! -MC P.S. - I'm running Centos 4.4

[Freeswitch-dev] Priority design in the event engine
by will 19 Sep '06

19 Sep '06

There are three priority levels in the event system - "NORMAL","HIGH" and "LOW". When I trace into "switch_event.c", a "for loop" can be found there. But it seems no effect on priority. I mean, it just pop and deliver events by turns. What's the meaning of priority in FreeSwitch? Will

The framework is there now for Python. It still has some hiccups but I think we can have them cleared up this weekend. Have questions let us know! Brian Fertig
