If no parameters are given then a warning is issued and<br>the current channel is hung up. If options are given but no channel is<br>specified then a warning is issued and the current channel is not hung up.<br><br>* Made the Bridge application give a verbose message instead of a warning<br>if the channel to bridge with is not specified and made not hang up the<br>current channel. As a result dialplan no longer needs to check if a<br>channel name is passed before calling Bridge and simply needs to check the<br>BRIDGERESULT channel variable instead. This is something you likely want<br>your dialplan to do anyway.<br><br>* Fixed up L() option warning message. It is up to the caller to<br>determine if the channel is hung up because of the warning. Dial() hangs<br>up the current channel while Bridge() does not.<br><br>Change-Id: I44349a8dc3912397f28852777de04f19e7bb9c73<br>---<br>M main/features.c<br>1 file changed, 15 insertions(+), 15 deletions(-)<br><br></pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;">git pull ssh://gerrit.asterisk.org:29418/asterisk refs/changes/13/13513/1</pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;"><span>diff --git a/main/features.c b/main/features.c</span><br><span>index 8c2d9bc..ab03bef 100644</span><br><span>--- a/main/features.c</span><br><span>+++ b/main/features.c</span><br><span>@@ -84,7 +84,9 @@</span><br><span> </synopsis></span><br><span> <syntax></span><br><span> <parameter name="channel" required="true"></span><br><span style="color: hsl(0, 100%, 40%);">- <para>The current channel is bridged to the specified <replaceable>channel</replaceable>.</para></span><br><span style="color: hsl(120, 100%, 40%);">+ <para>The current channel is bridged to the channel</span><br><span style="color: hsl(120, 100%, 40%);">+ identified by the channel name, channel name prefix, or channel</span><br><span style="color: hsl(120, 100%, 40%);">+ uniqueid.</para></span><br><span> </parameter></span><br><span> <parameter name="options"></span><br><span> <optionlist></span><br><span>@@ -893,7 +895,7 @@</span><br><span> config->warning_freq = atol(warnfreq_str);</span><br><span> </span><br><span> if (!config->timelimit) {</span><br><span style="color: hsl(0, 100%, 40%);">- ast_log(LOG_WARNING, "Bridge does not accept L(%s), hanging up.\n", limit_str);</span><br><span style="color: hsl(120, 100%, 40%);">+ ast_log(LOG_WARNING, "Bridge does not accept L(%s)\n", limit_str);</span><br><span> config->timelimit = config->play_warning = config->warning_freq = 0;</span><br><span> config->warning_sound = NULL;</span><br><span> return -1; /* error */</span><br><span>@@ -996,7 +998,7 @@</span><br><span> */</span><br><span> static int bridge_exec(struct ast_channel *chan, const char *data)</span><br><span> {</span><br><span style="color: hsl(0, 100%, 40%);">- struct ast_channel *current_dest_chan;</span><br><span style="color: hsl(120, 100%, 40%);">+ struct ast_channel *current_dest_chan = NULL;</span><br><span> char *tmp_data = NULL;</span><br><span> struct ast_flags opts = { 0, };</span><br><span> struct ast_bridge_config bconfig = { { 0, }, };</span><br><span>@@ -1017,22 +1019,20 @@</span><br><span> AST_APP_ARG(options);</span><br><span> );</span><br><span> </span><br><span style="color: hsl(0, 100%, 40%);">- if (ast_strlen_zero(data)) {</span><br><span style="color: hsl(0, 100%, 40%);">- ast_log(LOG_WARNING, "Bridge require at least 1 argument specifying the other end of the bridge\n");</span><br><span style="color: hsl(0, 100%, 40%);">- return -1;</span><br><span style="color: hsl(120, 100%, 40%);">+ tmp_data = ast_strdupa(data ?: "");</span><br><span style="color: hsl(120, 100%, 40%);">+ AST_STANDARD_APP_ARGS(args, tmp_data);</span><br><span style="color: hsl(120, 100%, 40%);">+ if (!ast_strlen_zero(args.options)) {</span><br><span style="color: hsl(120, 100%, 40%);">+ ast_app_parse_options(bridge_exec_options, &opts, opt_args, args.options);</span><br><span> }</span><br><span> </span><br><span style="color: hsl(0, 100%, 40%);">- tmp_data = ast_strdupa(data);</span><br><span style="color: hsl(0, 100%, 40%);">- AST_STANDARD_APP_ARGS(args, tmp_data);</span><br><span style="color: hsl(0, 100%, 40%);">- if (!ast_strlen_zero(args.options))</span><br><span style="color: hsl(0, 100%, 40%);">- ast_app_parse_options(bridge_exec_options, &opts, opt_args, args.options);</span><br><span style="color: hsl(0, 100%, 40%);">-</span><br><span> /* make sure we have a valid end point */</span><br><span style="color: hsl(0, 100%, 40%);">- current_dest_chan = ast_channel_get_by_name_prefix(args.dest_chan,</span><br><span style="color: hsl(0, 100%, 40%);">- strlen(args.dest_chan));</span><br><span style="color: hsl(120, 100%, 40%);">+ if (!ast_strlen_zero(args.dest_chan)) {</span><br><span style="color: hsl(120, 100%, 40%);">+ current_dest_chan = ast_channel_get_by_name_prefix(args.dest_chan,</span><br><span style="color: hsl(120, 100%, 40%);">+ strlen(args.dest_chan));</span><br><span style="color: hsl(120, 100%, 40%);">+ }</span><br><span> if (!current_dest_chan) {</span><br><span style="color: hsl(0, 100%, 40%);">- ast_log(LOG_WARNING, "Bridge failed because channel %s does not exist\n",</span><br><span style="color: hsl(0, 100%, 40%);">- args.dest_chan);</span><br><span style="color: hsl(120, 100%, 40%);">+ ast_verb(4, "Bridge failed because channel '%s' does not exist\n",</span><br><span style="color: hsl(120, 100%, 40%);">+ args.dest_chan ?: "");</span><br><span> pbx_builtin_setvar_helper(chan, "BRIDGERESULT", "NONEXISTENT");</span><br><span> return 0;</span><br><span> }</span><br><span></span><br></pre><p>To view, visit <a href="https://gerrit.asterisk.org/c/asterisk/+/13513">change 13513</a>.
