+# Extension to provide automatic caching of bundle server for pull

+"""pullbundle: automatic server side bundle caching
+
+General principle
+=================
+
+This extension provides a means for server to use pre-computed bundle for
+serving arbitrary pulls. If missing, the necessary pre-computed bundle will be
+generated on demand.
+
+To maximize usage of existing cached bundle, each pull will be served through
+multiple bundles. The bundle will be created using "standard range" from the
+"stablerange" principle. The "stablerange" concept if already used for
+obsmarkers discovery in the evolve extensions.
+
+Using pull Bundle
+=================
+
+All configuration is only required server side.
+
+The "stablerange" code currently still live in the evolve extensions, so for
+now enabling that extensions is required:
+
+You need at minimum the following configuration:
+
+    [extensions]
+    evolve=yes
+    pullbundle=yes
+    [experimental]
+    obshashrange.warm-cache = yes
+
+If you do not want to use evolution server side, you should disable obsmarkers exchange:
+
+    [experimental]
+    evolution.exchange=no
+
+Extra Configuration
+===================
+
+  [pullbundle]
+  # By default bundles are stored `.hg/cache/pullbundles/.
+  # This can be changed with the following config:
+  cache-directory=/absolute/path
+
+Implementation status
+=====================
+
+Both for stablerange and pullbundle use "simple" initial implementations.
+Theses implemenations focus on testing the algorithms and proving the features
+works. Yet they are already useful and used in production.
+
+Performances are expected to greatly improved in the final implementation,
+especially if some of it end up being compiled code.
+
+This first implementation lacks the ability to server the cached bundle from a
+CDN. We'll want this limitation to be lifted quickly.
+
+The way mercurial core report progress is designed for the receival of a single
+changegroup. So currently using pullbundle means flooding the user with output.
+This will have to be fixed.
+
+Why is does this live in the same repository as evolve
+======================================================
+
+There is no fundamental reasons for live in the same repository. However, the
+stablerange data-structure lives in evolve, so it was simpler to put this new
+extensions next to it. As soon as stable range have been upstreamed, we won't
+need the dependency to the evolve extension anymore.
