=== Some (interesting) contribution ===

 * major
   * production-ize chg: (still [[https://www.mercurial-scm.org/pipermail/mercurial-devel/2017-February/092547.html|on-going]])
   * hg absorb: easiest way to do small changes to a draft stack. see [[http://files.lihdd.net/hgabsorb-note.pdf|a note introducing the feature]]
   * fastannotate: an attempt to speed up `annotate`. see [[https://groups.google.com/forum/#!topic/mozilla.dev.version-control/nh4fITFlEMk|some perf numbers]]

 * less known / minor
   * timepad: a POC about what I think source control could be integrated into a modern editor. see [[https://quark-zju.github.io/timepad/|a demo]]
   * hg collate: an alternative implementation of `hg absorb -e`. see [[https://bitbucket.org/quark-zju/hgext-collate|the code]]
   * drawdag: a way to draw test cases using AsciiArts. see [[https://www.mercurial-scm.org/repo/hg/file/88203f26/tests/drawdag.py|the code]], and [[https://www.mercurial-scm.org/repo/hg/file/88203f26/tests/test-rebase-base.t|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 [[https://www.mercurial-scm.org/pipermail/mercurial-devel/2017-February/093442.html|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 [[https://bitbucket.org/quark-zju/hg-draft/commits/156d392a113017408ad3051a5c588025349a4028?at=splitword|a hacky POC]])
 * UUIDs in manifest to track renames (and give filelogs better names)
