Obsolescence is sometimes used only locally so the obs-marker users is always
the same. Showing the user in this case does not bring much values.
In the case where multiple users rewrite the commit, display the full list of
users. Also show all users in verbose mode.
Introduce an obsfate printer that uses all helpers functions defined in
obsutil to get all the obsfate-related data and format a string according to
the current format in test-obsmarker-template.t.
Then, introduce an obsfate templatekw that uses the obsfateprinter to return a
list of strings.
The goal is not to replace existing obsfate template functions but to propose
a default, good-enough and easily usable obsfate definition for end-users that
don't want to customize it. Such output would ultimately get included in the
default log output.
Here are some output examples for a commit amended:
rewritten using amend as 5:a9b1f8652753 by test (at 1970-01-01 00:00 +0000)
Next patches will make the output dependent on the verbosity.
Exemple of use-cases:
For having the obsfate on a single-line between brackets:
{if(obsfate, " [{join(obsfate, "; ")}]")}
For having the obsfate in several lines:
{if(obsfate, "{obsfate % " Obsfate: {fate}\n"}")}
Upon pull or unbundle, we display a message with the range of new revisions
fetched. This revision range could readily be used after a pull to look out
what's new with 'hg log'. The algorithm takes care of filtering "obsolete"
revisions that might be present in transaction's "changes" but should not be
displayed to the end user.
This changeset introduces a new documented test case for a distributed
obsolescence scenario. The scenario involves a simple case where some
obsolescence markers are retrieved before the changeset they affect. See the
test case documentation for details.
We also test variants where the changesets are added from a bundle.
This test file introduces documented test case for obsolescence markers usage
that are important to distributed workflow cases.
In the distributed case, new changesets, markers, and phases can be added in
orders that would not happen during the local only usage. Documenting these
scenarios and test them is important as we make progress with various
obsolescence aspects.
