| Summary | 0000141: Could not talk with ACS. Receive Empty message from ACS. | ||||
| Description | I have device running easycwmp. It works fine against test ACS. But when I change to another ACS which I have not full control. It has problems, that I doesn't appear to the ACS. I don't know what could be the reason. The log is like below: 2016-04-04 17:24:05 [easycwmp] NOTICE - add event '0 BOOTSTRAP' 2016-04-04 17:24:05 [easycwmp] NOTICE - add event '2 PERIODIC' 2016-04-04 17:24:05 [easycwmp] NOTICE - external script init config_init_local(65):: easycwmp.@local[0].port=7547 config_init_local(83):: easycwmp.@local[0].ubus_socket=/var/run/ubus.sock config_init_local(94):: easycwmp.@local[0].logging_level=3 config_init_local(71):: easycwmp.@local[0].username=xxx config_init_local(77):: easycwmp.@local[0].password=xxx config_init_local(55):: easycwmp.@local[0].interface=pppoe-wan config_init_acs(177):: easycwmp.@acs[0].periodic_enable=1 config_init_acs(183):: easycwmp.@acs[0].periodic_interval=3600 config_init_acs(190):: easycwmp.@acs[0].periodic_time=0001-01-01T00:00:00Z config_init_acs(165):: easycwmp.@acs[0].username=xxx config_init_acs(171):: easycwmp.@acs[0].password=xxx config_init_acs(159):: easycwmp.@acs[0].url=xxx 2016-04-04 17:24:05 [easycwmp] NOTICE -

Your ACS send empty message (http 204) after receiving Inform from CPE. I do not know if a some behaviour is allowed in the TR-069 because as I know the ACS should send InformResponse message when he get Inform message from the CPE |

what is your ACS? |

Hi, it is a commercial ACS. I found the problem is here: <soap_env:Envelope xmlns:soap_env="http://schemas.xmlsoap.org/soap/envelope/" [^] xmlns:soap_enc="http://schemas.xmlsoap.org/soap/encoding/" [^] xmlns:xsd="http://www.w3.org/2001/XMLSchema" [^] xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" [^] xmlns:cwmp="urn:dslforum-org:cwmp-1-2"> The attributes are separated by [CR] [LF]. The ACS cannot parse the attribute with it. I should change the separator to [SPACE]. I tried to change in message.h. But it seems not the correct one. How could I change it to SPACE, is this part of the libmicroxml, including the function mxmlLoadString()? Thank you. |

You have to change it in microxml |

I solved a similar problem, The attributes are separated by [LF],I changed the separator to [SPACE]: I fixed a fun according mohamed.kallel's suggestion In mxml_write_node() of microxml for (i = node->value.element.num_attrs, attr = node->value.element.attrs; i > 0; i --, attr ++) { width = strlen(attr->name); if (attr->value) width += strlen(attr->value) + 3; if (global->wrap > 0 && (col + width) > global->wrap) { //fixed //if ((*putc_cb)('\n', p) < 0) if ((*putc_cb)(' ', p) < 0) return (-1); col = 0; } |

Well, that ACS' XML parsing is crap, plain and simple. But that's hardly surprising. Really, it would make more sense for CWMP to ask libmicroxml to generate non-formatted XML, but when you do that, you also risk hitting line-length limits on broken quasi-XML parses. Someone in github had the idea of adding a space after the linefeed, instead of replacing the linefeed with a space. This would work with parsers that skip one and require the other, AND avoid generating long lines. But it won't work on parsers that can't handle LF separators at all... |

FWIW: https://github.com/pivasoftware/microxml/pull/5 Note that I don't have any such broken ACS'es around here to test if this is enough to fix things. Will also attach the patch here. |
