FreeSWITCH development Week in Review March 30th-April 5th

Submitted by kathleen on Tue, 04/08/2014 - 16:02

Hello, again. This week in the FreeSWITCH master branch we had 52 commits. We saw the addition of mod_basic to the FS languages to celebrate April Fool's day here in the US. Although it was added in the spirit of practical jokes, the addition of mod_basic highlights the extensive versatility of FS.
 
There was a continued drive toward improving build support for platforms such as BSD and Mac and mixed into this build work are large changes in functionally, such as ticket FS-353 leading the push toward converting the build system to prefer system versions of libraries, when compatible, over their in tree counterparts.
 
The following bugs were squashed:
 
19e3175 FS-6422: --resolve fixed a copy and paste error breaking socket_tcp_keepalive in mod_sofia
Jira: http://jira.freeswitch.org/browse/FS-6422
 
7532a7e FS-6310 fixed bug with orphaned calls in the show calls command
Jira: http://jira.freeswitch.org/browse/FS-6310
 
c02a5e6 fix for CSeq not being shared between FS boxes with ODBC backend in mod_sofia
Jira: http://jira.freeswitch.org/browse/FS-6413
 
9b56dff Say zero in time measurement only if it is neccessary in mod_say_hu
 
Improvements in cross platform build supports:
 
ab5ebd3 FS-6430: try to fix print_git_revision when running from builddir not inside src root
Jira: http://jira.freeswitch.org/browse/FS-6430
 
fb7fa3d update gitignore
 
5e90a5a FS-6430: fix running of print_git_revision from builddir not in src tree
Jira: http://jira.freeswitch.org/browse/FS-6430
 
0cc3a17 FS-6408: fix passing of CPPFLAGS to spandsp build
Jira: http://jira.freeswitch.org/browse/FS-6408
 
4bdef6e Fix detection of libedit on BSD
 
In terms of stability these were the use cases that were fixed:
 
287fd66 FS-6403 reverts commits 62ce8538974f727778f1024d0ef9549e438704fe and 3a85348cdfd0fd7df63a2a150790722c2d294b36 and fixed a segfault caused by a race issue in switch_xml
Jira: http://jira.freeswitch.org/browse/FS-6403
 
7151d6a fixed a segfault in hashtable

Hello, again. This week in the FreeSWITCH master branch we had a total of 34 commits submitted. Three of the major changes that were introduced this week were the deprecation of mod_spidermonkey to allow for replacement by mod_v8, work done in fs_cli to support the newer versions of libedit, and the lowering of the required version of sqlite to better support building FreeSWITCH out of the box on different platforms such as Debian 7 (Wheezy) and CentOS 6. To my knowledge, only the sqlite version 3.8.3.1 has been tested with any significance.
 
The following bugs were squashed:
 
f50f04b FS-6356: --resolve prevent libsofia from asserting(crash) when you change the time on the server forward by more than 15 days
Jira: http://jira.freeswitch.org/browse/FS-6356

4f54f91 Add back terminal detection for old libedits in fs_cli

Hello, again. This week in the FreeSWITCH master branch we had an amazing amount of work done with the majority of it going toward build support. The week ended with a total of 159 commits! Some big changes came with Freeswitch attempting to use the system versions of pcre, sqlite, speex, and curl rather than automatically using the in tree version.

FreeSWITCH is proud to announce that on April 1st 2014, we now have a new language module 'mod_basic'  That allows you to write dialplan applications in the BASIC programming language!  Now users from the golden era of home computing can join the ranks of the FreeSWITCH users!
 
Here is a demo IVR:
s$ = "hello "
s$ = s$ + "world "
s$ = s$ + "Happy April Fool's Day!"
FS_LOG "WARNING" s$ + "!"
 
FS_EXECUTE "answer"
FS_EXECUTE "sleep" "1000"
