03:06 PM Bug #2869 (Closed): NFD Restart Breaks Face Socket: If a Face is connected to a remote NFD using TcpTransport, an NFD restart will break the TCP socket. If the default c... Andrew Brown

03:34 PM Task #2860 (Closed): expressInterest should queue interests while async I/O is connecting: If an application calls expressInterest several times, the library needs to connect on the first call. With blocking ... Anonymous

12:39 PM Feature #2565: Implement async operations for Face.processEvents: Hi Andrew. A sanity check: In Python we have a Face subclass to dispatch pretty much every method call to the single ... Anonymous
12:28 PM Feature #2565: Implement async operations for Face.processEvents: Here's the commit to use synchronizedList for pendingInterestTable, etc. I tried to be careful not to call the callba... Anonymous
12:34 PM Bug #2846 (Closed): selfSign certificate name timestamp should be a version component: Anonymous

03:56 PM Bug #2847 (Closed): Created cert name should use lower-case ksk: Merged changes to master in all libraries. Anonymous
03:40 PM Bug #2847 (Closed): Created cert name should use lower-case ksk: IdentityStorage.getNewKeyName adds a name component starting with "KSK-". But it should be "ksk-" as required by the ... Anonymous

09:16 AM Feature #2565: Implement async operations for Face.processEvents: Sounds good; are you working in a specific branch? Andrew Brown

01:58 PM Bug #2846 (Resolved): selfSign certificate name timestamp should be a version component: Merged changes to master. Anonymous
01:05 PM Bug #2846 (Closed): selfSign certificate name timestamp should be a version component: When IdentityManager.selfSign creates the certificate name from the keyName, it just appends a name component with th... Anonymous
11:13 AM Feature #2565: Implement async operations for Face.processEvents: Hi Andrew. For starters, I'll switch the data structures like pendingInterestTable_ and interestFilterTable_ to use s... Anonymous

11:05 AM Feature #2565: Implement async operations for Face.processEvents: Ha, I hear you; the benefits of a single managed event loop are awesome, even if it does make JavaScript single-threa... Andrew Brown
10:30 AM Feature #2565: Implement async operations for Face.processEvents: .. or is the idea that code should use both: dispatch to "some thread" in a thread pool where that thread does a bloc... Anonymous
10:28 AM Feature #2565: Implement async operations for Face.processEvents: The problem with synchronized is that a call to a synchronized method is effectively a blocking call (until the other... Anonymous
10:14 AM Feature #2565: Implement async operations for Face.processEvents: I mean speed like how many more bytes could the async version process if the network channel is always saturated with... Andrew Brown

09:55 AM Feature #2565: Implement async operations for Face.processEvents: My idea for real-world CPU benchmarks of the event loop is to run on a Raspberry Pi and look at uptime. Hopefully, t... Anonymous

04:20 PM Feature #2565: Implement async operations for Face.processEvents: Makes sense; I wonder if there is a good way to benchmark the before and after for both speed and CPU time. Andrew Brown
04:09 PM Feature #2565: Implement async operations for Face.processEvents: Yes, the application will provide the thread pool to the library.
About the need for NIO, the concern is not for s... Anonymous

01:28 PM Feature #2565: Implement async operations for Face.processEvents: Yes, Java nio seems to have a different approach from Python, JavaScript and Boost. In those the library provides an ... Anonymous
01:11 PM Feature #2565: Implement async operations for Face.processEvents: I hadn't seen that one; I guess I thought the point of using NIO for jndn was to avoid the `while(true){ face.process... Andrew Brown

11:53 AM Feature #2565: Implement async operations for Face.processEvents: OK, thanks. I'll try to use a scheduled event for the interest timeout. Anonymous
11:50 AM Feature #2565: Implement async operations for Face.processEvents: This "loop" (actually it is event rescheduled every 100ms) is just a legacy part that is in pipeline to be replaced t... Alex Afanasyev
