py3kcompat: drop unused export

py3kcompat: don't convert os.environ to bytes os.environ accepts str not bytes. Assigning bytes will result in a run-time error.

demandimport: pass proper level to __import__ in Python 3 demandimport was failing in Python 3 with a ValueError because __import__'s level=-1 has gone away (-1 means to try both relative and absolute imports and relative imports don't exist in Python 3). With this patch, demandimport still doesn't work in Python 3 (it fails when importing a non-package module).

help: suggest keyword search when no topic is found When `hg help foobar` fails, it now suggests using `hg help --keyword foobar` instead of printing a full page of basic commands. This should greatly increases discoverability of the `hg help --keyword` argument.

help: provide a more helpful message when no keyword are matched Before this changeset, when no topic were matching the provided keyword ( in command such as `hg help --keyword babar`) the output was empty. This is confusing and unhelpful for new users seeking assistance in the help. We now display: $ hg help --keyword babar abort: no matches (try "hg help" for a list of topics) This send users in a new direction where they may find what they are looking for.

revsetbenchmark: use optparse to retrieve argument We need more flexibility. For example we'll want to run the benchmark on other repository.

revsetbenchmark: add a usage message when no arguments are passed This increase the odd someone who didn't wrote will it find out how to use this script.

revsetbenchmark: add `::tip and draft()` to the canonical list The want to test element on different side of the iterators.

revset: cosmetic changes in spanset range comparison We use the python syntax for range comparison: `a < x < c`. This is shorter, more readable and less error prone. This comparison escaped the cleanup make in e2031c8ca4f8

revset: drop spanset._contained All its users inlined it for performance reasons. (See 1d7a2771aa36 and e2031c8ca4f8)

patchbomb: includes series information in the header We includes information about the series being patch bombed in all email. Two new headers are added: * X-Mercurial-Series-Index: index of the patches in the series (starts at 1) * X-Mercurial-Series-Total: The total number of patches in the series This information is available in the email subject line, but having them formalized in the header will helps automated tools to process patches send with modern mercurial.

pager: add attend-<command> option This lets users override attend settings locally on a command granularity.

pager: variable reorder

pager: break auto out of command check loop
