Diff for "Release5.9"

New Features

• hg config now has a --source option to show where each

  • configuration value comes from.
• Introduced a command (debug-repair-issue6528) to repair repositories affected
  • by issue6528 where certain files would show up as modified even if they were clean due to an issue in the copy-tracing code.

New Experimental Features

• A changelogv2 format has been introduced. It is not ready for use yet, but

  • will be used later to address some of the weaknesses of the current revlog format.

• Initial experiment and support for dirstatev2, a new dirstate format that

  • addresses some of the weaknesses of the current dirstate format. Python + C and Rust support are being implemented, but the Rust solution is the one currently getting the attention for performance.

• Initial support for rhg status. rhg is the Rust wrapper executable for hg

  • that shortcuts some commands for faster execution speed.

Backwards Compatibility Changes

Internal API Changes

The Dirstate API have been updated as the previous function leaked some internal details and did not distinguish between two important cases: "We are changing parent and need to adjust the dirstate" and "some command is changing which file is tracked". To clarify the situation:

• the following functions have been deprecated,

  • dirstate.add,

  • dirstate.normal,

  • dirstate.normallookup,

  • dirstate.merge,

  • dirstate.otherparent,

  • dirstate.remove,

  • dirstate.drop,

  • dirstateitem.__getitem__,

• these new functions are added for the "adjusting parents" use-case:

  • dirstate.update_file,

  • dirstate.update_file_p1,

• these new function are added for the "adjusting wc file" use-case":

  • dirstate.set_tracked,

  • dirstate.set_untracked,

  • dirstate.set_clean,

  • dirstate.set_possibly_dirty,

See inline documentation of the new functions for details.

• Additionally, the following have been deprecated:

  • urlutil.getpath function

  • localrepository.updatecaches' full argument

• The following have been removed:

  • revlog.revlogio has been removed
