Some (interesting) contribution

• major

  • production-ize chg: (still on-going)

  • hg absorb: easiest way to do small changes to a draft stack. see a note introducing the feature

  • fastannotate: an attempt to speed up annotate. see some perf numbers

• less known / minor

  • timepad: a POC about what I think source control could be integrated into a modern editor. see a demo

  • hg collate: an alternative implementation of hg absorb -e. see the code

  • drawdag: a way to draw test cases using AsciiArts. see the code, and an example test

Random items in wishlist (in no particular order)

• In-memory DAG writes (waiting for smf)
• Sane obsolete markers cycle handling
• Cleaner (decoupled from Python.h) changelog index in C, so it could be better optimized

• Phase/head-based repoview. (see the preliminary idea)

• Unique linkrev per revision (by having some salt coming from the commit node)
• A separate blob layer (file nodes store blob IDs instead of file contents)
• More flexible graphlog (make things like issue5434 solvable, and allow more possibilities like diffing two DAGs)
• Backport a more correct yet efficient diff algorithm (bdiff outputs suboptimal results for large json files)

• Word-level merge (see a hacky POC)

• UUIDs in manifest to track renames (and give filelogs better names)
