UniMRCP 1.3.0 Released


UniMRCP 1.3.0 has been released and can be downloaded from the following location:
 
 
The regular source distributions prepackaged for Windows and Linux use are as always publicly available to everyone. The new binary distributions released for Windows and RHEL/CentOS 6 compliment the source distributions and are available to the UniMRCP members only. Note that members need to log in to gain access to additional resources.
 
The recommended version of the UniMRCP dependencies is:
 
 
While the source distributions can be used with the current and former versions of dependencies, the binary distributions have been built with unimrcp-deps-1.3.0 and require this exact version of the dependencies to be installed first. Further instructions on how to install binary packages (Windows installers and RHEL/CentOS 6 RPMs) will be published later. A new UniMRCP YUM repository is also under the way.
 
This release provides fixes for a number of issues reported by Coverity. The output directories layout now can be fully customized by user applications or be loaded from a configuration file. The GNU build has been enhanced to better support newer versions of autotools.
 
The client application and plugin integration interfaces retain backward compatibility. The only minor issue which may need to be addressed in your applications is support for the opaque apt_dir_layout interface. See the following post for more information:
 
 
Everybody is encouraged to upgrade. The detailed list of changes introduced in this release follows.
APR-toolkit library
  • Allow timers to be re-set. The ongoing timer, if any, will be implicitly stopped.
  • Added an optional timer support to the consumer task. This change requires the UniMRCP-deps 1.3.0 or above.
  • Slightly modified processing of start and termination requests in the apt_task interface.
  • Release task message, if the method signal() fails.
  • Added new methods to the apt_task interface to take a task offline: apt_task_offline() and to bring it back online: apt_task_online().
  • Use apr_ring instead of apt_obj_list to hold the task tree.
  • Compose native file paths by using APR_FILEPATH_NATIVE flag.
  • Enhanced apt_dir_layout interface to allow creation and loading of bare and extended layouts.
  • Made apt_dir_layout_t structure opaque. This change may incur insignificant changes in user applications.
  • While parsing a header field spanning multiple lines, check the return value of apt_text_line_read() first, and only then add the read line to the array.
  • Check the return value of apt_text_field_read() and only then, based on the result, use either apt_string_copy() or apt_string_reset().
  • Fixed a possible integer overflow in the poller and consumer tasks.
MPF library
  • Fixed a possible overflowed array index read (aka out-of-bound read) reported by Coverity.
  • Use memmove() instead of strcpy() for overlapping buffers.
  • While making calculations in mpf_codec_descriptor, cast to size_t first and only then multiply.
MRCP common library
  • In mrcp_header_field_add(), do not try to add the same header field twice. The second attempt would have failed anyway, though.
MRCP client library
  • Use apr_ring instead of apt_obj_list for MRCPv2 connections.
  • Use apr_filepath_merge() to compose native file paths while loading the client stack.
  • Append a UniMRCP version string to the SIP user agent field.
  • For SIP message logging, if enabled, compose a path relative to the log directory by default. Alternatively, a full path can be specified.
  • Fixed a potential NULL pointer dereference on processing of MPF messages.
  • Fixed a possible explicit NULL pointer dereference in mrcp_client_profile_create_ex().
  • Fixed a possible NULL pointer dereference which may occur when an invalid XML document name is specified in the configuration file.
  • Check the return value of apt_task_msg_acquire().
  • Separated declarations of MRCP client and server profiles.
MRCP server library
  • Use apr_ring instead of apt_obj_list for MRCPv2 connections.
  • Use a connection specific pool for apr_socket_accept(). This makes memory allocation for accepted sockets more predictable and prevents possible indefinite use of the shared pool.
  • Use apr_hash to hold pending control channels. Before, mrcp_connection was used as a temporary container.
  • Append a UniMRCP version string to the SIP user agent field.
  • For SIP message logging, if enabled, compose a path relative to the log directory by default. Alternatively, a full path can be specified.
  • Fixed a potential NULL pointer dereference on processing of MPF messages.
  • Fixed a possible NULL pointer dereference which may occur when an invalid XML document name is specified in the configuration file.
  • If channel->resource is a NULL pointer, do not dereference it while composing a log statement.
  • Separated declarations of MRCP client and server profiles.
RTSP library
  • Use apr_ring to hold a list of RTSP connections. This change allows to get rid of a sub-pool used for the connection list.
 Sofia-SIP module (MRCPv2 agent)
  • Let Sofia-SIP implicitly set the Contact header included in the transport parameter, when needed. This change fixes an interoperability problem with Avaya using SIP over TCP.
  • Do not uselessly check sip_contact->m_url against a NULL pointer, since m_url is actually an array but not a pointer.
  • In case of redirection (SIP 3xx responses), compose the To header based on the Contact using the API of Sofia-SIP.
  • Pass all the input parameters to nua_create() and do not unnecessarily call nua_set_params().
Miscellaneous
  • Remove automake generated build/compile script on maintainer-clean.
  • Use AM_CPPFLAGS instead of deprecated INCLUDES.
  • Use subdir-objects with AM_INIT_AUTOMAKE to prevent a bunch of warning messages encountered with automake 1.14.
  • Fixed support for out of tree build.
  • Use GNU standard 'sysconfdir' variable instead of custom 'confdir'.
  • Use APR_ENABLE_LAYOUT macro for pre-defined installation paths layouts.
  • Separated var and data directories. The var directory is supposed to hold files being created and modified on run-time.
  • Enhanced UNIMRCP_CHECK_SOFIA m4 macro to look not only for Sofia-SIP installed prefix and source/build tree but also for the full path to Sofia-SIP pkg-config file.
  • Added a new optional command-line argument '--dir-layout' to the applications unimrcpserver, unimrcpclient, and umc. The argument, if specified, allows to load a custom directories layout from the provided configuration file.
  • Use AM_PROG_CC_C_O macro in configure.ac, since automake 1.9 fails to generate Makefile.in when/if the option subdir-objects is specified with AM_INIT_AUTOMAKE but AM_PROG_CC_C_O is not used.
  • Added new configure enable/disable options to control build of libraries and applications located in the platforms directory.
  • Added uni_revision.h file to the repository. Removed utility project svnrev which was supposed to generate uni_revision.h.
  • Added a new #define UNI_REVISION_AT_LEAST(rev) which allows to check at compile time that the revision base number is at least a certain level.
  • Added missing project dependencies. This addresses command-line build: msbuild unimrcp-2010.sln.
  • Fixed mpftest application which had been broken for a while.
  • In log statements, use "Send/Receive Data" in place of "Send/Receive Stream".
  • Revised and simplified init.d script by using the standard init-script functions.
  • Took out obsolete inno-setup package creation scripts. The up-to-date versions are being maintained with other binary installers.

 

Thanks for using UniMRCP.
