sparse: vendor Facebook-developed extension
Facebook has developed an extension to enable "sparse" checkouts -
a working directory with a subset of files. This feature is a critical
component in enabling repositories to scale to infinite number of
files while retaining reasonable performance. It's worth noting
that sparse checkout is only one possible solution to this problem:
another is virtual filesystems that realize files on first access.
But given that virtual filesystems may not be accessible to all
users, sparse checkout is necessary as a fallback.
Per mailing list discussion at
https://www.mercurial-scm.org/pipermail/mercurial-devel/2017-March/095868.html
we want to add sparse checkout to the Mercurial distribution via
roughly the following mechanism:
1. Vendor extension as-is with minimal modifications (this patch)
2. Refactor extension so it is more clearly experimental and inline
with Mercurial practices
3. Move code from extension into core where possible
4. Drop experimental labeling and/or move feature into core
after sign-off from narrow clone feature owners
This commit essentially copies the sparse extension and tests
from revision 71e0a2aeca92a4078fe1b8c76e32c88ff1929737 of the
https://bitbucket.org/facebook/hg-experimental repository.
A list of modifications made as part of vendoring is as follows:
* "EXPERIMENTAL" added to module docstring
* Imports were changed to match Mercurial style conventions
* "testedwith" value was updated to core Mercurial special value and
comment boilerplate was inserted
* A "clone_sparse" function was renamed to "clonesparse" to appease
the style checker
* Paths to the sparse extension in tests reflect built-in location
* test-sparse-extensions.t was renamed to test-sparse-fsmonitor.t
and references to "simplecache" were removed. The test always skips
because it isn't trivial to run it given the way we currently run
fsmonitor tests
* A double empty line was removed from test-sparse-profiles.t
There are aspects of the added code that are obviously not ideal.
The goal is to make a minimal number of modifications as part of
the vendoring to make it easier to track changes from the original
implementation. Refactoring will occur in subsequent patches.

# patchbomb.py - sending Mercurial changesets as patch emails # # Copyright 2005-2009 Matt Mackall <mpm@selenic.com> and others # # This software may be used and distributed according to the terms of the # GNU General Public License version 2 or any later version. '''command to send changesets as (a series of) patch emails The series is started off with a "[PATCH 0 of N]" introduction, which describes the series as a whole. Each patch email has a Subject line of "[PATCH M of N] ...", using the first line of the changeset description as the subject text. The message contains two or three body parts: - The changeset description. - [Optional] The result of running diffstat on the patch. - The patch itself, as generated by :hg:`export`. Each message refers to the first in the series using the In-Reply-To and References headers, so they will show up as a sequence in threaded mail and news readers, and in mail archives. To configure other defaults, add a section like this to your configuration file:: [email] from = My Name <my@email> to = recipient1, recipient2, ... cc = cc1, cc2, ... bcc = bcc1, bcc2, ... reply-to = address1, address2, ... Use ``[patchbomb]`` as configuration section name if you need to override global ``[email]`` address settings. Then you can use the :hg:`email` command to mail a series of changesets as a patchbomb. You can also either configure the method option in the email section to be a sendmail compatible mailer or fill out the [smtp] section so that the patchbomb extension can automatically send patchbombs directly from the commandline. See the [email] and [smtp] sections in hgrc(5) for details. By default, :hg:`email` will prompt for a ``To`` or ``CC`` header if you do not supply one via configuration or the command line. You can override this to never prompt by configuring an empty value:: [email] cc = You can control the default inclusion of an introduction message with the ``patchbomb.intro`` configuration option. The configuration is always overwritten by command line flags like --intro and --desc:: [patchbomb] intro=auto # include introduction message if more than 1 patch (default) intro=never # never include an introduction message intro=always # always include an introduction message You can specify a template for flags to be added in subject prefixes. Flags specified by --flag option are exported as ``{flags}`` keyword:: [patchbomb] flagtemplate = "{separate(' ', ifeq(branch, 'default', '', branch|upper), flags)}" You can set patchbomb to always ask for confirmation by setting ``patchbomb.confirm`` to true.

The series starts with a "[PATCH 0 of N]" introduction, which describes the series as a whole. Each patch email has a Subject line of "[PATCH M of N] ...", using the first line of the changeset description as the subject text. The message contains two or three parts. First, the changeset description. With the -d/--diffstat option, if the diffstat program is installed, the result of running diffstat on the patch is inserted. Finally, the patch itself, as generated by :hg:`export`. With the -d/--diffstat or --confirm options, you will be presented with a final summary of all messages and asked for confirmation before the messages are sent. By default the patch is included as text in the email body for easy reviewing. Using the -a/--attach option will instead create an attachment for the patch. With -i/--inline an inline attachment will be created. You can include a patch both as text in the email body and as a regular or an inline attachment by combining the -a/--attach or -i/--inline with the --body option. With -B/--bookmark changesets reachable by the given bookmark are selected. With -o/--outgoing, emails will be generated for patches not found in the destination repository (or only those which are ancestors of the specified revisions if any are provided) With -b/--bundle, changesets are selected as for --outgoing, but a single email containing a binary Mercurial bundle as an attachment will be sent. Use the ``patchbomb.bundletype`` config option to control the bundle type as with :hg:`bundle --type`. With -m/--mbox, instead of previewing each patchbomb message in a pager or sending the messages directly, it will create a UNIX mailbox file with the patch emails. This mailbox file can be previewed with any mail user agent which supports UNIX mbox files. With -n/--test, all steps will run, but mail will not be sent. You will be prompted for an email recipient address, a subject and an introductory message describing the patches of your patchbomb. Then when all is done, patchbomb messages are displayed. In case email sending fails, you will find a backup of your series introductory message in ``.hg/last-email.txt``. The default behavior of this command can be customized through configuration. (See :hg:`help patchbomb` for details) Examples:: hg email -r 3000 # send patch 3000 only hg email -r 3000 -r 3001 # send patches 3000 and 3001 hg email -r 3000:3005 # send patches 3000 through 3005 hg email 3000 # send patch 3000 (deprecated) hg email -o # send all patches not in default hg email -o DEST # send all patches not in DEST hg email -o -r 3000 # send all ancestors of 3000 not in default hg email -o -r 3000 DEST # send all ancestors of 3000 not in DEST hg email -B feature # send all ancestors of feature bookmark hg email -b # send bundle of all patches not in default hg email -b DEST # send bundle of all patches not in DEST hg email -b -r 3000 # bundle of all ancestors of 3000 not in default hg email -b -r 3000 DEST # bundle of all ancestors of 3000 not in DEST hg email -o -m mbox && # generate an mbox file... mutt -R -f mbox # ... and view it with mutt hg email -o -m mbox && # generate an mbox file ... formail -s sendmail \\ # ... and use formail to send from the mbox -bm -t < mbox # ... using sendmail Before using this command, you will need to enable email in your hgrc.
