1461503 - "hg wip" error: "hg: parse error: unknown identifier: unstable"

Status: RESOLVED FIXED

(Developer Services :: Mercurial: configwizard, enhancement)

Description

[Chris Pearce [:cpearce (Not reading bugmail)]]

Running `hg wip` with Mercurial 4.6 results in the error "hg: parse error: unknown identifier: unstable".

This was on Windows with a fully mach bootstrap'd Firefox desktop (non-artefact build) setup, with a fully up to date evolve extension.

This is Tom Prince pointed out on IRC "It looks like the name of the revset changed from `unstable` to `orphan` (based on https://www.mercurial-scm.org/wiki/WhatsNew)"

Indeed, changing "unstable" to "orphan" in the wip revsetalias fixes the issue for me.

FTR, "orphan" was added in mercurial 4.4, so simply switching to orphan would break the command for mercurial < 4.4.

hg 4.6 has renamed the "unstable" revset expression to "orphan". This
commit adds a check to configwizard that fills in the appropriate
value based on the hg version.

The reason we didn't notice this in testing is that test-wip.t only tests
that wip is enabled in the hgrc file, not that it actually works as
intended. This commit adds a basic test to ensure the revspec does indeed
return references to some commits.
