Mini-NDN Version 0.7.0

Breaking Changes:

• Install behavior regarding existing installation of dependencies has been reversed; by default, these are now ignored. This is meant to clear up confusion regarding installing on existing installs which have been used for NDN development previously. The previous behavior can be enabled using --use-existing.

New features:

• Added NFDCBatch to NFDC helper, which allows the user to use the existing NFDC wrapper API to instead create and execute a batch file. When running large numbers of commands, this significantly speeds up performance due to not needing to add delay between individual CLI calls.
• Added MinindnAdhoc class which can be used to construct adhoc Mini-NDN-Wifi networks from topology files.
• Model mobility parameters can now also be passed to Mini-NDN-Wifi via topology files.
• Working directory can be passed as constructor argument to Minindn objects.
• We have added a new --release flag to the installer which simplifies installing matching releases of dependencies. Reference the install documentation for more information.
• Experimental wifi support for NLSR helper. See experiment docs for details (issue: 5232).
• Added a Dockerfile for Mini-NDN. A prebuilt image for linux/amd64 platforms is available on the GitHub container registry.
• The previous testbed topology generation script has been deprecated and removed. Please reference the NDN Play website for a replacement.

Improvements:

• Ethernet unicast faces are now supported natively by NLSR wrapper, NFDC wrapper, and NDN routing helper. No additional formatting by the user is needed for ethernet addresses extracted from the Mininet API when passed to these functions (issue: 5321).
• NdnRoutingHelper has been parallelized along with minor optimizations. You can now also use it to create permanent faces (issue: 5264).
• checkConvergence method of Experiment helper can now output more detailed information when flag returnConvergenceInfo is set (issue: 5236)
• getPopen can now accept commands formatted as lists as well as strings
• We now natively edit nfd.conf files using infoconv to read and write it as json rather than calling infoedit at the shell (issue: 5318)
• Added Sprint PoP topology
• Link bandwidth value (bw) can now be specified as decimal megabits rather than only integers in topology files
• NFDC was significantly refactored for the NFDCBatch change

Bug fixes:

• NFDC helper properly supports existing faces and no longer outputs unnecessary error messages if face exists by default
• Fixed out of date ndnsec commands
• Socket path now defaults to NFD default as of release 24.07. You can specify a different path with the defaultSocketLocation argument in the Nfd object constructor (issue: 5309).
• Fixed jitter being parsed into incorrect type from topology files
• Moved vestigial CLI arguments relating to wifi_ping.py example out of the Mini-NDN-Wifi class
