A common usecase for export is to preview the patch that will be patchbombed or
to see what changed in a revision found by bisect. Showing the working
directory parent is thus a useful and obvious default.
'export' is the official export format and used by patchbomb, but it would only
show date as a timestamp that most humans might find it hard to relate to. It
would be very convenient when reviewing a patch to be able to see what
timestamp the patch will end up with.
Mercurial has always used util.parsedate for parsing these headers. It can
handle 'all' date formats, so we could just as well use a readable one.
'export' will now use the format used by 'log' - which is the format described
as 'Unix date format' in the templating help. We assume that all parsers of '#
HG changeset patch'es can handle that.
This violated user expectation. Updated the code to clobber files, but
preserve the behavior of appending multiple patches requested in a
single export. Includes tests.
The export command didn't output the diffs in color, even when color support
was enabled. This patch fixes that by making the export command use the default
ui.write method, instead of directly manipulating the ui.fout file object.
Also added a test case to verify color output to test-export.t.
Many tests didn't change back from subdirectories at the end of the tests ...
and they don't have to. The missing 'cd ..' could always be added when another
test case is added to the test file.
This change do that tests (99.5%) consistently end up in $TESTDIR where they
started, thus making it simpler to extend them or move them around.
