| Description |
|
Remote command only can send 2048 bytes characters to agent. It's worth to send more long characters for agent in some case, for instance complex commands, send notification message on agent side etc. I suggest it will be increased to 65535 bytes that is action message size limitation. |

(1) There was a memory leak in case zbx_check_user_parameter() is not successful. Fixed that in r49531. Please take a look. sasha Thanks! CLOSED |

(2) For trunk branch, the new implementation of add_user_parameter() leaves "error" buffer uninitialized in some cases, which leads to a bad error message on the command line: $ sbin/zabbix_agentd -t 'echo[1]' zabbix_agentd [15580]: ERROR: cannot add user parameter "echo [*],echo $1": }��� It used to be like that: $ sbin/zabbix_agentd -t 'echo[1]' zabbix_agentd [15261]: ERROR: cannot add user parameter "echo [*],echo $1": syntax error sasha RESOLVED in r49612. asaveljevs CLOSED |
