* Service RegisterServer and Discovery (#687)
* New RegisterServer service
Add support for Discovery Server (LDS/GDS) by providing RegisterServer service.
FindServers service is updated to return the registered servers.
* Add examples for discovery server
* Use compile switch for LDS
* Use periodic jobs for server register
* Add lastSeen for registered servers and fix compilation errors
* Add cleanup of stale registrations
* Fix UA_string output with printf (use `%.*s`)
* Use correct port number
* LDS customizable timeout for automatic de-register (#695)
* Enable valgrind for unit tests and fix memory leaks
* Fix build errors introduced by cmake rewrite in current master
* LDS customizable timeout for automatic de-register
* LDS-ME (using mDNS) (#730)
* Enable coveralls for Pro/open62541
* Move periodic server register functionality into core implementation
* Add mDNS library as dependency
* Cleanup and enable Mingw x64 on Appveyor
* Set define for mDNS dll
* Fix memory leak
* Check for defined variable to aviod deleting root dir
* Add LDS-ME
LDS Multicast Extension using mDNS for service discovery according to OPC UA Part 12
To be implemented:
- RegisterServer2
- FindServersOnNetwork
- GDS has to call FindServers on all known LDS
* Update to most recent schema definition from https://opcfoundation.org/UA/schemas/Opc.Ua.Types.bsd.xml
* Update to most recent node ids from https://opcfoundation.org/UA/schemas/NodeIds.csv
* Implement RegisterServer2 and FindServersOnNetwork
* Fix memory leak
* Use clang-3.7 because older scan build finds invalid bug
* Fix for mDNS class comparison if value is signed
* cosmetic cleanup (untabify, indention)
* fix after rebase
* Use monotonic clock for timeouts
* Fix crash of register server caused by invalid memory
* Set correct job id for periodic server register
* Use valid SD DNS name ([servername]._opcua-tcp._tcp.[hostname]. -> [servername]-[hostname]._opcua-tcp._tcp.local.)
Set A record for SD DNS
* Remove output of last seen time, since it is now monotonic and thus not human readable
* Fix removal of all remaining DNS records
* Fix discovery test due to previous changes
* Get interface ip addresses for windows
* Update mdnsd submodule
* Additional check output
* Also set A record for hostname
* Send multicast query to _opcua-tcp._tcp.local to find other servers after startup
* Update mdnsd
* Update mdnsd
* Limit mDNS label to max 63 chars according to DNS RFC
* Fix rebase issues
* fix a cppcheck issue for unreachable code
* Untabify
* Check if path or caps is set in TXT record
* Do not remove (TTL=0) `_services._dns-sd._udp.local.` because it may still be used by other PC in the net.
* Update mdnsd
* Fix correct construction of hostname if it is shorter than 63 chars
* Fix correct construction of hostname if it is shorter than 63 chars
* fixup
* Fix correct construction of hostname if it is shorter than 63 chars
* fixup
* Fix correct construction of hostname if it is shorter than 63 chars
* Fix correct construction of hostname if it is shorter than 63 chars
* fixup
* RegisterServer does not require a session
* untabify where it lead to compiler-warnings (if-guards)
* Update mdnsd
* Allow changing the LDS URL for RegisterServer and set default value if NULL
* Typo
* add Callbacks for RegisterServer and mDNS detection
* untabify
* Setting correct port for DiscoveryServer using NetworkLayer information. Better use of UA_EndpointUrl_split
* Include isTxtReceived parameter in callback
* Fix access after free
* Add EndpointUrl to CreateSessionRequest
* Copy&Paste error
* Fix#769: Wrong NodeIDs offset for BinaryEncoding
* fixup
* Fix#769: Wrong NodeIDs offset for BinaryEncoding
* Add additional node ids for previous change of binary encoding offset
* Also check for UA_STATUSCODE_BADSERVICEUNSUPPORTED
* Check correct response code
* Avoid double loops for finding correct node id
* Remove findDataType
* Disable xmlEncodingId for now
* Use UA_UInt64 for repeated job interval
UA_UInt32 for interval in nsec means maximum interval of 429 seconds -> too small
* Fix conversion to UInt64
* Move SplitEndoint into ua_connection.h
* Create specific method for splitting endpoint url. Fix#778
* Windows wants strncpy_s
* Port is max 6 chars
* Fix uninitialized parameter warning
* Handle path without leading slash
* Additional unit tests to cover discovery functionalities
* Untabify
* Fix broken build after merge
* Fix after merge
* fix after merge
* fix after merge
* Removed undef SLIST
* Readd missing BSD_SOURCE define needed for mdns
* Use correct define for amalgamation
* Add missing header for cygwin on Windows
* Fix compilation errors on windows using Visual Studio
* Fix double free
* If applicationType is set to DiscoveryServer, set it to Server
See http://forum.unified-automation.com/topic1987.html
* Fixup for merge
* fix output of UA_String
* Small bug fixes
* Fixup after merge
* Fixup 2 after merge
* Add missing library if win32 compile
* Delete server after test
* Fix wrong positive clang warnings
* Add additional assert for NULL
* Add additional assert for NULL
* Fix MS build
* Additional NULL check for clang analyzer
* Fix MS Build
* Fix#950 wrong requestServer structure passed to registerServer callback.
