New submission from Wes Garland <wes at page.ca>:
I am on 1.9.1 but believe this applies to tip as well.
When merging a master repo that has a sub-repo with no changes but a newer
rev, you get an error like:
"abort: outstanding uncommitted changes in subrepository 'web/htdocs'"
when in fact the error should say something like:
"abort: outstanding uncommitted change of subrepository revision for
'web/htdocs'"
There's a subtle difference there, and it confuses users here regularly.
Users not aware of this bad error message cd to the subrepository and try to
check in changes only to discover that there are none. Then they wind up
making useless changes and randomly checking crap in until "magically" hg
lets them merge.
Here's a log of me using hg in my day-to-day activities which illustrates
the provenance of the buggy error message clearly:
