• Add script for dockerized development shell (#479) * Add script for dockerized development shell * Fix queue dropping test
• Subscriber concurrency review (#478) * Lock access to SubscriberManager public methods Prevent subscribe during unsubscribe critical section. * Unsubscribing an unsubscribed topic is an error This branch must not be ignored. * Cleanup some redundant syntax in subscribers impl
• Fix queue blocking (#464) * Unblock QueueMessageHandler.handle_message The thread was holding the lock while pushing to a potentially blocking function. Rewrite the logic and use a deque while we're at it. * Add test for subscription queue behavior Guarantee that the queue drops messages when blocked.
• Python 3 updates/fixes (#460) * rosbridge_library, rosbridge_server: Update package format Add Python3 conditional dependencies where applicable. * rosbridge_library: Fix pngcompression for Python 3 * rosapi: Use catkin_install_python for scripts
• Fixing wrong header/stamp in published ROS-messsages (#472) When publishing a message to ROS (i.e. incoming from rosbridge_server's perspective), timestamps in the Header attributes all point to the same Time object iff the message contains multiple Header attributes (typically the case if a ROS message contains other ROS messages, e.g. ...Array-types) and rosparam use_sim_time is true.

0.11.4 (2020-02-20)

• Concurrency review (#458) * Safer locking in PublisherConsistencyListener * Safer locking in ros_loader * Print QueueMessageHandler exceptions to stderr * Register before resuming outgoing valve * Don't pause a finished socket valve
• Add cbor-raw compression (#452) The CBOR compression is already a huge win over JSON or PNG encoding, but it’s still suboptimal in some situations. This PR adds support for getting messages in their raw binary (ROS-serialized) format. This has benefits in the following cases: - Your application already knows how to parse messages in bag files (e.g. using [rosbag.js](https://github.com/cruise-automation/rosbag.js), which means that now you can use consistent code paths for both bags and live messages. - You want to parse messages as late as possible, or in parallel, e.g. only in the thread or WebWorker that cares about the message. Delaying the parsing of the message means that moving or copying the message to the thread is cheaper when its in binary form, since no serialization between threads is necessary. - You only care about part of the message, and don't need to parse the rest of it. - You really care about performance; no conversion between the ROS binary format and CBOR is done in the rosbridge_sever.
• Fix typos in rosbridge_library's description (#450)
• Python 3 fix for dict::values (#446) Under Python 3, values() returns a view-like object, and because that object is used outside the mutex, we were getting RuntimeError: dictionary changed size during iteration under some circumstances. This creates a copy of the values, restoring the Python 2 behaviour and fixing the problem.

0.9.0 (2018-04-09)

• Fix typo in function call
• Add missing argument to InvalidMessageException (#323) Add missing argument to InvalidMessageException constructor
• Make unregister_timeout configurable (#322) Pull request #247 introduces a 10 second delay to mitigate issue #138. This change makes this delay configurable by passing an argument either on the command line or when including a launch file. Usage example: `xml <launch> <include file="$(find rosbridge_server)/launch/rosbridge_websocket.launch"> <arg name="unregister_timeout" value="5.0"/> </include> </launch> ` Closes #320

• add graceful_shutdown() method to advertise_service capability This gives the service a bit of time to cancel any in-flight service requests (which should fix #265). This is important because we busy-wait for a rosbridge response for service calls and those threads do not get stopped otherwise. Also, rospy service clients do not currently support timeouts, so any clients would be stuck too. A new test case in test_service_capabilities.py verifies the fix works
• Add rostest for service capabilities and fix bugs also fixed some typos
• Fix Travis config (#311) * fix Travis config dist: kinetic is currently unsupported * fix rostests for some reason, rostest seems to hide the rosout node - changed tests to use other services

0.7.17 (2017-01-25)

• adjust log level for security globs Normal operation (i.e. no globs or successful verification of requests) is now silent, with illegal requests producing a warning.
• add missing import
• correct default values for security globs also accept empty list as the default "do not check globs" value in addition to None. Finally, append rosapi service glob after processing command line input so it's not overwritten
• Added services_glob to CallServices, added globs to rosbridge_tcp and rosbridge_udp, and other miscellanous fixes.
• As per the suggestions of @T045T, fixed several typos, improved logging, and made some style fixes.
• Added new parameters for topic and service security. Added 3 new parameters to rosapi and rosbridge_server which filter the topics, services, and parameters broadcast by the server to match an array of glob strings.

0.6.1 (2014-09-01)

• Handle float infinity and NAN s
• Windows-related fix for PIL Image module import
• Fixed typo in raising type errors.
• something messed up indentation not sure how that could happen, worked here.
• map Inf and NaN to null JSON does not support Inf and NaN values. Currently they are just written into the JSON and JSON.parse on the client side will fail. Correct is to map them to null which will then be parsed correctly by JSON.parse on the client side. The issue with that is that the shortcut for lists of floats might be impossible (maybe someone else with more experience in python comes up with something else?). Maybe something similar is necessary in the to_inst case, but I can not really test them. Real world application is to process laser scans, they contain inf and nan values for some drivers if the measurements are invalid or out of range.
• Update .travis.yml and package.xml for rosbridge_library tests
• Put back unregister for the publisher and clarify the reconnect behavior of the test case. The exponential backoff of the client causes hard to understand timing of the events. All specs passed locally on hydro: SUMMARY * RESULT: SUCCESS * TESTS: 103 * ERRORS: 0 * FAILURES: 0
• Add copyright notice to the file
• Remove extra whitespace
• Make the test more deterministic
• Remove circular dependency.

• Fixed wrong unicode encoding
• support publishing non-ascii letters
• Added error message on result=False When call_service returns False as result, values contains the error message.
• added parameter lookup to rosbridge_tcp.py, modules where those are used, and default parameters to launch file; internal default-values still get used when launch-file does not provide them; internal defaults can be changed within rosbridge_tcp.py
• Merge branch 'experimental_branch' into new_features
• fix handling of partial/multiple/broken json by avoiding to pass nested json (without op-field) to rosbridge.. probably still needs more complex handling of incoming 'broken' json
• nested service not MiRoR related anymore
• added singleton for request-list; allows provider to send service response without specifying module and type, they get looked up when response is received via request_id
• fix for nested service responses - use ros_loader and message_conversion for populating an according instance
• use message_conversion in handle_servie_request
• snapshot for branch to show to genpy devs
• using float64 instead of std_msgs/Float64 lets scripts run fine.. ; next: fix with using std_msgs/Float64 --> need nested data field

• added TODO: check if service successfully registered in ros
• added description of new opcodes
• tests, comments, description, ..
• tested rosbridge_websocket with new capabilities; websocket test scripts not working yet..; but new caps are working when using rosbridge_websocket and tcp2ws wrapper --> so only testscripts need to be fixed for websockets.

• need to implement server side blocking of multiple requests, to keep implementation of service provider as easy and simple as possible
• not finished
• some changes.. still needs serveral fixes
• unique request_ids
• fixed deserialization of multiple fragments in incoming-data; was caused by too short delay between socket-sends (<0.2 seconds); maybe only temp. fixed
• added fragment sorting to test-client and test-server
• message_size debugging; TODO: sort list of received fragments! ; make sure receive_buffers are big enough for fragment_size + header..
• minor changes
• testing: service server fragmentsizes receive: 1 send: 1; client fragmentsize receive: 1; is working..
• fixed an error that caused service_response to appear quoted as string once too often; should be ok now
• fragmentation basically working; service_server can request fragmented service_calls, service_client can request fragmented responses; fragmentation can be requested by adding fragmentation_size parameter to any message sent to rosbridge
• some code cleanup
• set service_request_timeout back to 60 seconds; had 2s from timeout_tests..
• fixed example: non-ros_service_server.py to use only 1 socket; commented and structured code and comments in test-scripts
• some minor changes: comments, debug-output, ..
• added test script for non-ros_service_client calling service from non-ros_service_server
• added msg and srv files
• fixed (removed) dependency to beginner_tutorials for service_server test-scripts. beginner_tutorials package not needed anymore.
