 occurs. So server operators should prepare for some people to follow these
 instructions when a failure occurs, thus driving more load to the original
 Mercurial server when the bundle hosting service fails.
+
+
+inline clonebundles
+-------------------
+
+It is possible to transmit clonebundles inline in case repositories are
+accessed over SSH. This avoids having to setup an external HTTPS server
+and results in the same access control as already present for the SSH setup.
+
+Inline clonebundles should be placed into the `.hg/bundle-cache` directory.
+A clonebundle at `.hg/bundle-cache/mybundle.bundle` is referred to
+in the `clonebundles.manifest` file as `peer-bundle-cache://mybundle.bundle`.
+
+
+auto-generation of clone bundles
+--------------------------------
+
+It is possible to set Mercurial to automatically re-generate clone bundles when
+enough new content is available.
+
+Mercurial will take care of the process asynchronously. The defined list of
+bundle-type will be generated, uploaded, and advertised. Older bundles will get
+decommissioned as newer ones replace them.
+
+Bundles Generation:
+...................
+
+The extension can generate multiple variants of the clone bundle. Each
+different variant will be defined by the "bundle-spec" they use::
+
+    [clone-bundles]
+    auto-generate.formats= zstd-v2, gzip-v2
+
+See `hg help bundlespec` for details about available options.
+
+By default, new bundles are generated when 5% of the repository contents or at
+least 1000 revisions are not contained in the cached bundles. This option can
+be controlled by the `clone-bundles.trigger.below-bundled-ratio` option
+(default 0.95) and the `clone-bundles.trigger.revs` option (default 1000)::
+
+    [clone-bundles]
+    trigger.below-bundled-ratio=0.95
+    trigger.revs=1000
+
+This logic can be manually triggered using the `admin::clone-bundles-refresh`
+command, or automatically on each repository change if
+`clone-bundles.auto-generate.on-change` is set to `yes`.
+
+    [clone-bundles]
+    auto-generate.on-change=yes
+    auto-generate.formats= zstd-v2, gzip-v2
+
+Automatic Inline serving
+........................
+
+The simplest way to serve the generated bundle is through the Mercurial
+protocol. However it is not the most efficient as request will still be served
+by that main server. It is useful in case where authentication is complexe or
+when an efficient mirror system is already in use anyway. See the `inline
+clonebundles` section above for details about inline clonebundles
+
+To automatically serve generated bundle through inline clonebundle, simply set
+the following option::
+
+    auto-generate.serve-inline=yes
+
+Enabling this option disable the managed upload and serving explained below.
+
+Bundles Upload and Serving:
+...........................
+
+This is the most efficient way to serve automatically generated clone bundles,
+but requires some setup.
+
+The generated bundles need to be made available to users through a "public" URL.
+This should be donne through `clone-bundles.upload-command` configuration. The
+value of this command should be a shell command. It will have access to the
+bundle file path through the `$HGCB_BUNDLE_PATH` variable. And the expected
+basename in the "public" URL is accessible at::
+
+  [clone-bundles]
+  upload-command=sftp put $HGCB_BUNDLE_PATH \
+      sftp://bundles.host/clone-bundles/$HGCB_BUNDLE_BASENAME
+
+If the file was already uploaded, the command must still succeed.
+
+After upload, the file should be available at an url defined by
+`clone-bundles.url-template`.
+
+  [clone-bundles]
+  url-template=https://bundles.host/cache/clone-bundles/{basename}
+
+Old bundles cleanup:
+....................
+
+When new bundles are generated, the older ones are no longer necessary and can
+be removed from storage. This is done through the `clone-bundles.delete-command`
+configuration. The command is given the url of the artifact to delete through
+the `$HGCB_BUNDLE_URL` environment variable.
+
+  [clone-bundles]
+  delete-command=sftp rm sftp://bundles.host/clone-bundles/$HGCB_BUNDLE_BASENAME
+
+If the file was already deleted, the command must still succeed.

-to make it easier on you.
+Minimum Supported Rust Version
+------------------------------
+
+The minimum supported rust version (MSRV) is specified in the `Clippy`_
+configuration file at ``rust/clippy.toml``. It is set to be ``1.61.0`` as of
+this writing, but keep in mind that the authoritative value is the one
+from the configuration file.
+
+We bump it from time to time, with the general rule being that our
+MSRV should not be greater that the version of the Rust toolchain
+shipping with Debian testing, so that the Rust enhanced Mercurial can
+be eventually packaged in Debian.
+
+To ensure that you are not depending on features introduced in later
+versions, you can issue ``rustup override set x.y.z`` at the root of
+the repository.

+------------------------------------------------
+
+  $ cp -ar reference-repo strip-unrelated
+  $ cd strip-unrelated
+
+The internal change is not directly stripped, but it is affected by the strip
+and it is in the "temporary backup" zone. The zone that needs to be put in a

+  $ hg debugstrip --hidden $shelved_node

+
+Explicitly bundling the internal change
+=======================================
+
+  $ cd reference-repo
+
+try to bundle it alone explicitly
+---------------------------------
+
+We should not allow it
+
+  $ hg bundle --type v3 --exact --rev $shelved_node --hidden ../internal-01.hg
+  abort: cannot bundle internal changesets
+  (1 internal changesets selected)
+  [255]
+  $ hg debugbundle ../internal-01.hg
+  abort: $ENOENT$: '../internal-01.hg'
+  [255]
+
+try to bundle it with other, somewhat explicitly
+------------------------------------------------
+
+We should not allow it
+
+  $ hg bundle --type v3 --exact --rev 'desc(b)':: --hidden ../internal-02.hg
+  abort: cannot bundle internal changesets
+  (1 internal changesets selected)
+  [255]
+  $ hg debugbundle ../internal-02.hg
+  abort: $ENOENT$: '../internal-02.hg'
+  [255]
+
+bundle visible ancestors
+------------------------
+
+This should succeed as the standard filtering is skipping the internal change naturally
+
+  $ hg bundle --type v3 --exact --rev 'desc(b)':: ../internal-03.hg

+====================================
+Test for the stabletailgraph package
+====================================
+
+This test file contains a bunch of small test graphs with some minimal yet
+non-trivial structure, on which the various stable-tail graph and stable-tail
+sort functions are tested.
+
+Each case consists of the creation of the interesting graph structure, followed
+by a check, for each noteworthy node, of:
+- the stable-tail sort output (with the linear parts globbed),
+- the leap set,
+- the specific leap set.
+
+In the ASCII art of the diagrams, the side of the exclusive part which is
+followed in priority is denoted with "<" or ">" if it is on the left or right
+respectively.
+
+The intermediary linear parts in the example graph are there to force the
+exclusive part choice (made on a min rank condition).
+
+
+Setup
+=====
+
+Enable the rank computation to test sorting based on the rank.

+Example 3: shadowing of a final leap
+====================================
+
+We have a merge "f" whose exclusive part contains a merge "d".
+
+The inherited parent of "d" is not in the exclusive part of "f".
+At the end of the exclusive part of "d",
+the leap to "c" is shadowed by the leap to "e", i.e. the inherited part to "f".

+Example 4: skipping over nested exclusive part (entirely)
+=========================================================
+
+We have a merge "f" whose exclusive part contains a merge "d".
+
+The exclusive part of "d" is not in the exclusive part of "f".
+However, some of the inherited part of "d" is part of the exclusive part of "f"
+and needs to be iterated over before leaping to the inherited part of "f".
+
+The sort of "d" is partially reused for the ordering of the exclusive part of
+"f". However the reused part is not contiguous in the sort of "d".

+
+We have a merge "f" whose exclusive part contains a merge "d".
