revlog: skeleton support for version 2 revlogs
There are a number of improvements we want to make to revlogs
that will require a new version - version 2. It is unclear what the
full set of improvements will be or when we'll be done with them.
What I do know is that the process will likely take longer than a
single release, will require input from various stakeholders to
evaluate changes, and will have many contentious debates and
bikeshedding.
It is unrealistic to develop revlog version 2 up front: there
are just too many uncertainties that we won't know until things
are implemented and experiments are run. Some changes will also
be invasive and prone to bit rot, so sitting on dozens of patches
is not practical.
This commit introduces skeleton support for version 2 revlogs in
a way that is flexible and not bound by backwards compatibility
concerns.
An experimental repo requirement for denoting revlog v2 has been
added. The requirement string has a sub-version component to it.
This will allow us to declare multiple requirements in the course
of developing revlog v2. Whenever we change the in-development
revlog v2 format, we can tweak the string, creating a new
requirement and locking out old clients. This will allow us to
make as many backwards incompatible changes and experiments to
revlog v2 as we want. In other words, we can land code and make
meaningful progress towards revlog v2 while still maintaining
extreme format flexibility up until the point we freeze the
format and remove the experimental labels.
To enable the new repo requirement, you must supply an experimental
and undocumented config option. But not just any boolean flag
will do: you need to explicitly use a value that no sane person
should ever type. This is an additional guard against enabling
revlog v2 on an installation it shouldn't be enabled on. The
specific scenario I'm trying to prevent is say a user with a
4.4 client with a frozen format enabling the option but then
downgrading to 4.3 and accidentally creating repos with an
outdated and unsupported repo format. Requiring a "challenge"
string should prevent this.
Because the format is not yet finalized and I don't want to take
any chances, revlog v2's version is currently 0xDEAD. I figure
squatting on a value we're likely never to use as an actual revlog
version to mean "internal testing only" is acceptable. And
"dead" is easily recognized as something meaningful.
There is a bunch of cleanup that is needed before work on revlog
v2 begins in earnest. I plan on doing that work once this patch
is accepted and we're comfortable with the idea of starting down
this path.

First, enable the extension as explained in 'hg help extensions', and register the hook you want to run. "incoming" and "changegroup" hooks are run when changesets are received, while "outgoing" hooks are for changesets sent to another repository: [hooks] # one email for each incoming changeset incoming.notify = python:hgext.notify.hook # one email for all incoming changesets changegroup.notify = python:hgext.notify.hook # one email for all outgoing changesets outgoing.notify = python:hgext.notify.hook This registers the hooks. To enable notification, subscribers must be assigned to repositories. The "[usersubs]" section maps multiple repositories to a given recipient. The "[reposubs]" section maps multiple recipients to a single repository: [usersubs] # key is subscriber email, value is a comma-separated list of repo patterns user@host = pattern [reposubs] # key is repo pattern, value is a comma-separated list of subscriber emails pattern = user@host A "pattern" is a "glob" matching the absolute path to a repository, optionally combined with a revset expression. A revset expression, if present, is separated from the glob by a hash. Example: [reposubs] */widgets#branch(release) = qa-team@example.com This sends to "qa-team@example.com" whenever a changeset on the "release" branch triggers a notification in any repository ending in "widgets". In order to place them under direct user management, "[usersubs]" and "[reposubs]" sections may be placed in a separate "hgrc" file and incorporated by reference: [notify] config = /path/to/subscriptionsfile Notifications will not be sent until the "notify.test" value is set to "False"; see below. Notifications content can be tweaked with the following configuration entries: notify.test If "True", print messages to stdout instead of sending them. Default: True. notify.sources Space-separated list of change sources. Notifications are activated only when a changeset's source is in this list. Sources may be: "serve" changesets received via http or ssh "pull" changesets received via "hg pull" "unbundle" changesets received via "hg unbundle" "push" changesets sent or received via "hg push" "bundle" changesets sent via "hg unbundle" Default: serve. notify.strip Number of leading slashes to strip from url paths. By default, notifications reference repositories with their absolute path. "notify.strip" lets you turn them into relative paths. For example, "notify.strip=3" will change "/long/path/repository" into "repository". Default: 0. notify.domain Default email domain for sender or recipients with no explicit domain. notify.style Style file to use when formatting emails. notify.template Template to use when formatting emails. notify.incoming Template to use when run as an incoming hook, overriding "notify.template". notify.outgoing Template to use when run as an outgoing hook, overriding "notify.template". notify.changegroup Template to use when running as a changegroup hook, overriding "notify.template". notify.maxdiff Maximum number of diff lines to include in notification email. Set to 0 to disable the diff, or -1 to include all of it. Default: 300. notify.maxsubject Maximum number of characters in email's subject line. Default: 67. notify.diffstat Set to True to include a diffstat before diff content. Default: True. notify.merge If True, send notifications for merge changesets. Default: True. notify.mbox If set, append mails to this mbox file instead of sending. Default: None. notify.fromauthor If set, use the committer of the first changeset in a changegroup for the "From" field of the notification mail. If not set, take the user from the pushing repo. Default: False. If set, the following entries will also be used to customize the notifications: email.from Email "From" address to use if none can be found in the generated email content. web.baseurl Root repository URL to combine with repository paths when making references.
