* dlt-daemon: Output current number of connections as defaultYusuke Sato2018-12-211-15/+18
| | | | | | | | | | In previous, number of connections was output only if verbose mode in dlt.conf was enabled. This information is basically useful and is not output frequently. Therefore number of connections information is made to output as default when new connection is established or the connection is lost. Signed-off-by: Yusuke Sato <yusuke-sato@apn.alpine.co.jp>

* Remove one-instance-lock mechanismJeevan Ramakant Nagvekar2018-12-211-31/+1
| | | | | | | | | | | | | | This commit removes DLT's "one-instance-lock" mechanism. In daemonized mode, on first instance, a file is created (if not already created) and locked. If second instance is attempted file locking fails since the file is already locked by first instance. This prevents new instance of the DLT daemon. After analysis its found that there is no need of any mechanism for prevention of another instance. The same is already taken care by socket mechanism. Since main socket is created by first instance, attempt to create it again with same port number fails. Signed-off-by: Jeevan Ramakant Nagvekar <jeevan.nagvekar1@wipro.com>

* dlt-daemon: Output signal number at exit (#68)Yusuke Sato2018-05-291-7/+8
| | | | | | | | | | | So far, signal number had been output in signal handler. However this was not so safety. And when syslog was used as log output destination of dlt_log(), we could not see any info in the same Life Cycle. So dlt_log() is removed from signal handler and signal number is newly output by DLT message and dlt_log() at exit. This info will help analysis why dlt-daemon exits.

* dlt-daemon: Avoid to output duplicated application registration message (#63)Yusuke Sato2018-05-231-11/+21
| | | | | | | | | | | | | | | | If application tries to send application registration request before dlt-daemon startup, the request is sent twice as below: 1. Buffered request in user library buffer 2. New request when user app succeeds to attach to dlt-daemon In previous, dlt-daemon had been output the registration messages 2 times even though these messages were come from same application. This duplicated output is avoided by this change. Warning message in case of dlt-runtime-context.cfg exists is also avoided. This file is created when Control message: "Store Config" is used. This is not irregular case. Signed-off-by: Yusuke Sato <yusuke-sato@apn.alpine.co.jp>
* dlt-daemon: Not output Context un-/registration DLT message by default (#62)Yusuke Sato2018-05-231-5/+11
| | | | | | | | | | | This patch changes Context un-/registration message not to output DLT by default for the purpose of reducing trace messages. Actually dlt-daemon already sends almost same meaning control message which can show Context un-/registration([get_log_info] and [unregister_context]). These are duplicate message and should be suppressed in normal case. Only if "Verbose = 1" is set in dlt.conf, the messages are output as same as before.

| | | | | | | | | | | | - When dlt_daemon_user_send_log_level() called in dlt_daemon_process_user_message_register_context() fails -1 was returned which caused dlt_daemon_process_user_messages() to stop processing receiver buffer.

| | | | | | | | | | | | | | | | | | | | | | | | On context and application registration, the data needs to be read in 2 parts. If the first part was at the end of the receiver buffer, it was wrongly removed whereas the complete data is not full received and therefore interpretable. This has to be fixed by not removing the data before everything is checked. Thus, while readjusting the buffer to the first found header, the offset was not properly updated. Signed-off-by: Frederic Berat <fberat@de.adit-jv.com> Process User Messages: Fix buffer handling In case application and context registration the buffer need to be read two times. But before removing the data, the data need to be readjusted to its origin. This was missing in a previous fix.

* Dlt MultiNodeChristoph Lipka2015-12-071-116/+249
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MultiNode allows to connect DLT Daemons running on different operating systems, e.g. in a virtualized environment. The central component is the Gateway DLT Daemon which connects external DLT Clients, like the DLT Viewer running on a host computer, with Passive DLT Daemons running on nodes without a physical connection to external DLT clients. The Gateway DLT Daemon itself acts as a DLT client when connecting to a Passive DLT Daemon. To use the Gateway functionality, it has to be enabled in dlt.conf: GatewayMode = 1 All communication between passive nodes and DLT Viewer has to be send via the Gateway node. The Gateway node forwards log messages coming from passive nodes to all connected DLT clients. It also forwards command and control requests coming from DLT clients to the corresponding passive node. The Gateway DLT Daemon read a configuration file (dlt_gateway.conf) at startup with information about Passive DLT Daemon connections. Afterwards, the Daemon will try to connect to the passive DLT Daemons. If the connection cannot be established after the configured timeout, the Gateway DLT Daemon will give up connecting. The configuration file has to contain the following information about a passive node: [PassiveNode1] IPaddress = 192.168.2.35 Port = 3490 EcuID = ECU2 Connect = OnStartup ; timeout in seconds Timeout = 10 Precondition is, that the passive node is configured with the correct ECU id, ECU2 in this case. If the passive node sends messages with another than configured ECU id, the Gateway DLT Daemon will shut down the connection. It is also possible to connect to a passive DLT daemon using the dlt-passive-node-ctrl application. In this case "Connect=OnDemand" has to be configured in the configuration file. To connect to PassiveNode1, "dlt-passive-node-ctrl -n ECU2 -c 1" has to be executed. With "dlt-passive-node-ctrl -s" the status of passive node connections can be retrieved.

* DltLogstorage: Logstorage CacheChristoph Lipka2015-11-241-6/+23
| | | | | | | | | | | | | | | | | | When using DltLogstorage on internal storage device, it is needed to reduce writing to internal storage device as much as possible. This patch introduces sync strategies to Logstorage to provide that functionality. The ON_MSG strategy is the default sync strategy that flushes every written log message to the storage device (fflush). The ON_DAEMON_EXIT strategy only flushes data to disk when the daemon exits. The strategy can be defined per filter in the dlt_logstorage.conf configuration file by adding SyncBehavior=<Strategy> to a configuration. Signed-off-by: Christoph Lipka <clipka@jp.adit-jv.com>

* Unix socket control interfaceChristoph Lipka2015-11-241-0/+162
| | | | | | | | | | | | | | | | Control applications running in the same Linux OS should be able to communicate with the DLT Daemon via a socket connection. To be able to do that, the DLT Client library need to be extended. DLT Clients connected via this UNIX socket are not handled as normal DLT Clients and no log messages will be forwarded to them. This avoids problems in situations when a control application is connected to the DLT Daemon before any other 'real' DLT Client (e.g. DLT Viewer) is connected. In this situations, all already stored log messages are flushed to the control application and therefore lost, because the control application most likely ignore all incoming messages besides the one in which it is interested in.

* dlt-daemon: Implement epoll based event handlingFrederic Berat2015-11-111-283/+226
| | | | | | | | | | | | | | | | | | | | | | | | | | | The event handling has been reworked in order to use epoll and restructure the code. There are 2 new structures. The DltConnection which contains all basic connection information, like the type, the file descriptor, and the receiver structure corresponding. The DltEventHandler that manages the DltConnections and the associated events. The concept is basically the following. The daemon will create different connections, serial connections, socket connections, fifos etc ... Each of them will then register itself to the event handler, and give it the ownership of this connection. From this point in time, the daemon can act on the connections. Once an event is triggered, the event handler will call the connection specific callback, creates new connections when clients arrives, and potentially destroy the connection in case of hangup. On exit, the daemon cleanup the event handler, which leads to the destruction of the connections. The work there is a first step for a global restructuring. Several modification will follow, in order to rationalize the different daemon structures, and avoid variable and code duplication. Signed-off-by: Frederic Berat <fberat@de.adit-jv.com>

* Fixed INTERNAL-mode connection bug in dlt-daemonSven Hassler2015-10-071-1/+1
| | | | | | | | | | | When logging-mode of the DLT-daemon was set to DLT_USER_MODE_INTERNAL or DLT_USER_MODE_OFF and a client tried to connect to the daemon, the socket for accepting new connections would be closed. This would make connecting to the daemon impossible, even if the logging mode was reset to DLT_USER_MODE_EXTERNAL or DLT_USER_MODE_BOTH. Fixed this by removing conditional check on the logging mode - clients connections are always accepted now. If the logging-mode is being switched from INTERNAL to EXTERNAL or BOTH while a client is connected, the client will then start to receive messages normally.
