Now that the 'vfs' classes moved in their own module, lets use the new module
directly. We update code iteratively to help with possible bisect needs in the
future.
Now that style are carried by the 'ui' object, we no longer need complicated
logic to restore the original style. We just need to copy the 'ui' and work on
the copied version.
This is the last bits we needed to move out of the extensions. 'hgext/color.py'
now only contains logic to changes the default color behavior to 'auto'.
However, more cleanups are on the way and we need to document the new config
directly in core.
New revsetlang module hosts parser, tokenizer, and miscellaneous functions
working on parsed tree. It does not include functions for evaluation such as
getset() and match().

get*() functions are aliased since they are common in revset.py.
This commit introduces functionality for upgrading a repository in
place. The first part that's implemented is testing for upgrade
"compatibility." This is done by examining repository requirements.
There are 5 functions returning sets of requirements that control
upgrading. Why so many functions? Mainly to support extensions.
Functions are easier to monkeypatch than module variables.
Astute readers will see that we don't support "manifestv2" and
"treemanifest" requirements in the upgrade mechanism. I don't have
a great answer for why other than this is a complex set of patches
and I don't want to deal with the complexity of these experimental
features just yet. We can teach the upgrade mechanism about them
later, once the basic upgrade mechanism is in place.
This commit also introduces the "upgraderepo" function. This will be
our main routine for performing an in-place upgrade. Currently, it
just implements requirements checking. The structure of some code in
this function may look a bit weird (e.g. the inline function that is
only called once). But this will make sense after future commits.
Currently, if Mercurial introduces a new repository/store feature or
changes behavior of an existing feature, users must perform an
`hg clone` to create a new repository with hopefully the
correct/optimal settings. Unfortunately, even `hg clone` may not
give the correct results. For example, if you do a local `hg clone`,
you may get hardlinks to revlog files that inherit the old state.
If you `hg clone` from a remote or `hg clone --pull`, changegroup
application may bypass some optimization, such as converting to
generaldelta.
Optimizing a repository is harder than it seems and requires more
than a simple `hg` command invocation.
This commit starts the process of changing that. We introduce
`hg debugupgraderepo`, a command that performs an in-place upgrade
of a repository to use new, optimal features. The command is just
a stub right now. Features will be added in subsequent commits.
This commit does foreshadow some of the behavior of the new command,
notably that it doesn't do anything by default and that it takes
arguments that influence what actions it performs. These will be
explained more in subsequent commits.
This patch introduces a new 'raw' argument (defaults to False) to revlog's
revision() and _addrevision() methods.
When the 'raw' argument is set to True, it indicates the revision data should be
handled as raw data by the flagprocessor.
Note: Given revlog.addgroup() calls are restricted to changegroup generation, we
can always set raw to True when calling revlog._addrevision() from
revlog.addgroup().
This move contains the first reference to debugrevlogopts in
debugcommands.py. We'll eventually want to move that over. We
hold off for now because it would introduce a module import cycle.
