Summary: cadmium could grow some predicates so nightly doesn't
have to parse hg output
Product: SCM Migration
Version: unspecified
Platform: SPARC (32bit+64bit)
OS/Version: Solaris 11/Nevada
Status: NEW
Severity: enhancement
Priority: P3
Component: cdm
AssignedTo: scm-migration-dev at opensolaris.org
ReportedBy: sommerfeld at sun.com
i've prototyped a mostly simple mercurial extension which makes scripting
around hg pull / hg merge / hg update a little less nervewracking. maybe this
extension should be folded into cadmium.
these could also allow a bunch of the code in nightly which parses hg command
output (grepping for the default/english version of human-readable messages
which are actually internationalized...) to be less sketchy.
I have the following predicates defined as hg subcommands in my extension:
"single-parent"
returns true if the working copy has only a single parent (which is true if
there isn't a half-completed merge in progress)
"single-head"
returns true if there's only one head in the workspace.
"needs-merge"
returns true if there's more than one head in the workspace.
"unmodified"
returns true if the workspace contains uncommitted modifications to tracked
files (adds, modifies, removes, and deleted/missing files)
"full-auto-merge"
returns true if an hg merge is known to require no manual intervention
(because of no overlap in files touched, etc.)
