![]() I can confirm, for a few records I looked, in and out records are empty (gdb) print (*$tree.m_buckets.m_entry.get().m_pitEntries. PIT entries leaked by the above manner should have no in-record and no can you look at the coredump and confirm there is no in-record and no out-record? With DNL, a duplicate Nonce can be detected from DNL even if the PIT entry is new, and then PIT entry is leaked. Without DNL, duplicate Nonce detection relies on the PIT entry, and it's impossible for an incoming Interest to be detected as having duplicate Nonce if the PIT entry is newly created, so step2 cannot happen. This is a design problem introduced with Dead Nonce List (DNL, #1953). Click 'Erase' from the Disk Utility options. Open Applications > Utilities > Disk Utility Find your external hard drive in the list of drives. If you move files to linux, or have Git Bash on your PC, and have access to the find command, you might also be able to do this: find. Since most external hard drives are formatted for PCs, before the backup of your Mac begins you need to format the hard drive for macOS. no timer is set in Interest loop pipeline You can use dotclean command to remove or merge the.a duplicate Nonce is detected, so control flow goes to Interest loop pipeline.in incoming Interest pipeline, a new PIT entry is created (which comes without timers).The control flow that can leak a PIT entry is: Days in Previous Period DATEDIFF ( Start of Previous Period, End of Previous Period,DAY) Now if I add all of these measure to the report with card visuals again I can see previous period calculation works correctly With every change you apply in date range slicer you can see the previous period calculates the range again, it will be. The blue line indicates the portions of this control flow where neither timer is set.Īs we can see, there is one blue line that continues toward the termination of forwarding pipelines, and this is where a PIT entry leak can happen. The photo shows 6 forwarding pipelines that contain operations of setting or cancelling the timers, highlighted in red. I found one code path that can lead to a PIT entry left without either timer. Therefore, I suspect this is a bug in forwarding pipelines: in certain conditions, there exists a code path that causes a PIT entry not to have either timer afterwards, this PIT entry is leaked if there isn't another incoming packet that causes a pipeline execution on this PIT entry. However, note-1 note-5 note-6 can mostly rule out this Bug being caused by Interests with large InterestLifetime.ĭuring 20160301 call, Alex reveals that from the coredump he took on REMAP gateway router several hours after the end of NdnCon conference, he could see that InterestLifetime of most packets are 2 seconds, and both unsatisfy timer and straggler timer are empty.īy design of forwarding pipelines, a PIT entry should have either timer set at all times (exception: if pipeline is executing when coredump is taken, the one PIT entry used in the executing pipeline is exempt). There are discussions about imposing an upper bound of allowable InterestLifetime, but such practice violates NDN service semantics and should be settled with #2551. Tested on Mac OS X 10.9 (Mavericks) with git -version reporting 1.8.3.4 (Apple Git-47).Interests with large InterestLifetime can legitimately stay in the PIT for a long time. gitignore same result - the pattern worked and suppressed the directories. I also reran the test (after cleaning up the first one) using */bin in. So, the regexes (globs?) can be made to work. gitignore to add Thing*.Thing/bin thus: Thing*.Thing/bin The directories now show up in git as needing to be added. I added files to the directories: $ for d in Thing?.Thing/bin do cp qs.c $d done There is no content in the directories, so there's nothing for git to track, so they are not listed as needing to be tracked. No changes added to commit (use "git add" and/or "git commit -a") In this case, ChronoSync is warning us that file ownership is being ignored on the destination volume, which is a very common condition for external drives. " to discard changes in working directory) I ran: $ for number in $(seq 1 9) do mkdir -p Thing$number.Thing/bin done
