Version 5.1

[bockthom]

5.1

Added

• Add the possibility to split networks that contain simplified edges (PR Implement splitting of simplified networks #278, 9798d33, 0ed437c, 67a6651, 98ef831, 7ec4d83, 637d62a, 2c70666, 1cbc6fa, 41788ff, b042c0d, 36d23d6, 402c256, 54af2b1, 894414a, 0fe32a2)
• Add functionality for commit-message content analysis, such as NLP tools including stemming, tokenization, and lemmatization, as well as a function to search for keywords in commit messages and a function to measure the length of the messages (PR Add functionalities to analyze the content of commit messages #281, 5aa4e41, 99f0638, e469d3a, 7d8fd39, ef689f7, 6e64224, f544394, dd9246b)
• Add unlist.timestamps.if.possible parameter to get.edgelist.with.timestamps which allows callers to request a conversion of the timestamps from list to vector if possible, i.e., when there are no simplified edges in the network (PR Correctly handle date attributes in list format in 'get.edgelist.with.timestamps' #289, 39bf1dd)

Changed/Improved

• For consistency reasons: Ensure that the values of edge attributes are always lists even when they represent singular values (PR Implement splitting of simplified networks #278, 6fae184, 416c817)
• Reduce the amount of redundantly built networks by caching network data internally. This should improve the performance of building multi-networks, especially, when parts of the multi-networks have been built before (Improve construction of multi-relation networks #119, PR Internally cache network data instead of networks to reduce redundancy in network construction #282, 06a814c, 4793eab, 8ba907f, 28d2290, 3608214, b30c7f2, 1fa340d, 40cd554, 8fcc744, ca348f1, 1d233af, 5dd5fc1)
• Internally cache commit-network data and bipartite-network data similarly to how we cache network data for author-, and artifact-networks (PR Internally cache network data instead of networks to reduce redundancy in network construction #282, PR Miscellaneous fixes and improvements in network construction #285, 3608214, aa7e3fa)
• Ensure that configured or implicitly-enforced undirectedness in partial networks is always dominant over configured or implicitly-enforced directedness. Furthermore, ensure consistency in the directedness used for edge generation and as a network attribute, especially in networks that consist of multiple partial networks such as multi-networks (PR Internally cache network data instead of networks to reduce redundancy in network construction #282, 65ead39, a776caf, 257a1c8, 41cff01)
• Remove redundant entries from the list of allowed edge attributes and instead add event.info.1 and event.info.2 (PR Internally cache network data instead of networks to reduce redundancy in network construction #282, 1b156c1)
• Allow the issue data attributes event.info.1 and event.info.2 on network edges (PR Internally cache network data instead of networks to reduce redundancy in network construction #282, 1b156c1)
• Add a network.type parameter to get.networks in which the caller can specify the types of networks to be constructed. This improves performance in cases where not all network types are needed, such as when building multi-networks (PR Miscellaneous fixes and improvements in network construction #285, bc2efd6, e9a0c16)
• Rename the list.attributes parameter in add.vertex.attribute and split.and.add.vertex.attribute to flatten.values with inverted semantics and introduce documentation for it to improve comprehensibility (PR Miscellaneous fixes and improvements in network construction #285, 7dab04a)
• Sort author data by author.name instead of author.id when reading it from a file (PR Enhance the codeface data for testing #286, 61b538b)
• Enhance codeface testing data by ensuring that commit ids are unique between proximity and feature data and by adding commit data that includes (1) different commits that touch the same file / function, (2) commits that are authored at the same time by different authors (PR Enhance the codeface data for testing #286, 7481099, 3e53285)
• Deprecate support for R version 4.0 because of breaking dependencies (PR Add functionalities to analyze the content of commit messages #281, 3dc91b1)

Fixed

• Fix a bug in construct.edge.list.from.key.value.list that could cause a crash when constructing a network where different vertices have identical associated timestamps (PR Miscellaneous fixes and improvements in network construction #285, d694a68)
• Fix a bug in network construction that could lead to edges having an unwanted author.name.1 attribute (PR Miscellaneous fixes and improvements in network construction #285, 105fec1)
• Ensure that POSIXct values are correctly handled in add.vertex.attribute, i.e., that they are not converted to numeric values (PR Miscellaneous fixes and improvements in network construction #285, 7dab04a, 4924ac2)
• Handle empty edges when constructing commit networks using commit-interaction data (PR Miscellaneous fixes and improvements in network construction #285, d5e1e48)
• Correctly retain order of commit and mail data when merging it with PAStA, synchronicity, and commit message data (PR Enhance the codeface data for testing #286, 50b9b68)
• Fix get.edgelist.with.timestamps to work correctly on networks with dates in default (list) format (PR Correctly handle date attributes in list format in 'get.edgelist.with.timestamps' #289, 35b34bf)
