blackbox: also log alias expansions This should be extremely useful for helping users debug without having to see their complete configuration. Shell aliases do not get their expansion logged, because we don't look and see if we're in a repo before we dive into the execution of a shell alias. As a result, the ui object doesn't know where to log.

test-clonebundles: accept another error string here This is what happens if you run the test in a FreeBSD Jail, rather than "connection refused".

tests: guard test-archive-symlink with unziplinks check This fixes the test on FreeBSD, where the stock unzip doesn't understand symlinks.

hghave: add a check for unzip(1) that understands symlinks unzip(1) from the FreeBSD base system does not understand symlinks, so test-archive-symlinks is busted.

test-https: drop two spurious --traceback flags These make test failures scarier than they are.

extensions: change magic "shipped with hg" string I've caught multiple extensions in the wild lying about being 'internal', so it's time to move the goalposts on people. Goalpost moving will continue until third party extensions stop trying to defeat the system.

version: add formatter support The license message isn't exported, which I don't think is useful and I couldn't find a way to restructure it for JSON or template outputs.

version: factor out mapping of internal/external labels Prepares for formatter support, where translation should be disabled conditionally.

version: always build list of extension versions This patch just moves "if ui.verbose:" to the inner loop, as preparation for formatter support.

formatter: add fm.nested(field) to either write or build sub items We sometimes need to build nested items by formatter, but there was no convenient way other than building and putting them manually by fm.data(): exts = [] for n, v in extensions: fm.plain('%s %s\n' % (n, v)) exts.append({'name': n, 'ver': v}) fm.data(extensions=exts) This should work for simple cases, but doing this would make it harder to change the underlying data type for better templating support. So this patch provides fm.nested(field), which returns new nested formatter (or self if items aren't structured and just written to ui.) A nested formatter stores items which will later be rendered by the parent formatter. fn = fm.nested('extensions') for n, v in extensions: fn.startitem() fn.write('name ver', '%s %s\n', n, v) fn.end() Nested items are directly exported to a template for now: {extensions % "{name} {ver}\n"} There's no {extensions} nor {join(extensions, sep)} yet. I have a plan for them by extending fm.nested() API, but I want to revisit it after trying out this API in the real world.
