hgweb: fix diff hunks filtering by line range in webutil.diffs() The previous clause for filter out a diff hunk was too restrictive. We need to consider the following cases (assuming linerange=(lb, ub) and the @s2,l2 hunkrange): <-(s2)--------(s2+l2)-> <-(lb)---(ub)-> <-(lb)---(ub)-> <-(lb)---(ub)-> previously on the first and last situations were considered. In test-hgweb-filelog.t, add a couple of lines at the beginning of file "b" so that the line range we will follow does not start at the beginning of file. This covers the change in aforementioned diff hunk filter clause.

summary: display obsolete state of parents Extend the "parent: " lines in summary to display "(obsolete)" when the parent is obsolete.

templates: add "changeset.obsolete" label in command line style Following respective change in cmdutil.changeset_printer.

templates: shorten definition of changeset labels in command-line style We'll add more labels and the line is already quite long, so let's define a variable to hold all evolution "troubles" labels.

templates: use separate() to build changeset labels in command-line style

templatekw: add an "obsolete" keyword Definition is the same as the one in evolve extension.

cmdutil: add a "changeset.obsolete" label in changeset_printer Until now there were no label to highlight obsolete changesets in log output, only evolution troubles (unstable, bumped, divergent) are supported. We add a "changeset.obsolete" label on changeset entries produced by changeset_printer so that obsolete changesets can be highlighted in log output. This is useful because, unless using a graph log where obsolete changesets have a 'x' marker, there's no way to identify obsolete changesets. And even in graph mode, when working directory's parent is obsolete, we get a '@' marker and we do not see it as obsolete.
