stream-clone: add a v3 version of the protocol

This new version is less rigid regarding the extract number of files and number
of bytes to be actually transfered, it also lays the groundwork for other
improvements.

The format stays experimental, but this is an interesting base to build upon.

Test generation through the dedicated command
=============================================

  $ cat >> ../server/.hg/hgrc << EOF
  > [clone-bundles]
  > auto-generate.on-change = no
  > EOF

Check the command can generate content when needed
--------------------------------------------------

Do a push that makes the condition fulfilled,
Yet it should not automatically generate a bundle with
"auto-generate.on-change" not set.

  $ touch quoi
  $ hg -q commit -A -m 'add quoi'

  $ pre_push_manifest=`cat ../server/.hg/clonebundles.manifest|f --sha256 | sed 's/.*=//' | cat`
  $ pre_push_upload=`ls -1 ../final-upload|f --sha256 | sed 's/.*=//' | cat`
  $ ls -1 ../server/.hg/tmp-bundles

  $ hg push

  added 1 changesets with 1 changes to 1 files

  $ post_push_manifest=`cat ../server/.hg/clonebundles.manifest|f --sha256 | sed 's/.*=//' | cat`
  $ post_push_upload=`ls -1 ../final-upload|f --sha256 | sed 's/.*=//' | cat`
  $ ls -1 ../server/.hg/tmp-bundles
  $ test "$pre_push_manifest" = "$post_push_manifest"
  $ test "$pre_push_upload" = "$post_push_upload"

Running the command should detect the stale bundles, and do the full automatic
generation logic.

  $ hg -R ../server/ admin::clone-bundles-refresh

Test modification of configuration
==================================

Testing that later runs adapt to configuration changes even if the repository is
unchanged.

adding more formats
-------------------

bundle for added formats should be generated

change configuration

  $ cat >> ../server/.hg/hgrc << EOF
  > [clone-bundles]
  > auto-generate.formats = v1, v2
  > EOF

refresh the bundles

  $ hg -R ../server/ admin::clone-bundles-refresh
  clone-bundles: starting bundle generation: v1
  11 changesets found

the bundle for the "new" format should have been added

  $ cat ../server/.hg/clonebundles.manifest
  file:/*/$TESTTMP/final-upload/full-v1-11_revs-4226b1cd5fda_tip-*_acbr.hg BUNDLESPEC=v1 REQUIRESNI=true (glob)

  full-v2-10_revs-3b6f57f17d70_tip-*_acbr.hg (glob)
  $ ls -1 ../server/.hg/tmp-bundles

Changing the ratio
------------------

Changing the ratio to something that would have triggered a bundle during the last push.

  $ cat >> ../server/.hg/hgrc << EOF
  > [clone-bundles]
  > trigger.below-bundled-ratio = 0.95
  > EOF

refresh the bundles

  $ hg -R ../server/ admin::clone-bundles-refresh
  clone-bundles: starting bundle generation: v2
  11 changesets found


the "outdated' bundle should be refreshed

  $ cat ../server/.hg/clonebundles.manifest
  file:/*/$TESTTMP/final-upload/full-v1-11_revs-4226b1cd5fda_tip-*_acbr.hg BUNDLESPEC=v1 REQUIRESNI=true (glob)
  file:/*/$TESTTMP/final-upload/full-v2-11_revs-4226b1cd5fda_tip-*_acbr.hg BUNDLESPEC=v2 REQUIRESNI=true (glob)

  full-v2-11_revs-4226b1cd5fda_tip-*_acbr.hg (glob)
  $ ls -1 ../server/.hg/tmp-bundles

Test more command options
=========================

bundle clearing
---------------

  $ hg -R ../server/ admin::clone-bundles-clear
  clone-bundles: deleting bundle full-v1-11_revs-4226b1cd5fda_tip-*_acbr.hg (glob)
  clone-bundles: deleting bundle full-v2-10_revs-3b6f57f17d70_tip-*_acbr.hg (glob)
  clone-bundles: deleting bundle full-v2-11_revs-4226b1cd5fda_tip-*_acbr.hg (glob)

Nothing should remain

  $ cat ../server/.hg/clonebundles.manifest
  $ ls -1 ../final-upload
  $ ls -1 ../server/.hg/tmp-bundles

background generation
---------------------

generate bundle using background subprocess
(since we are in devel mode, the command will still wait for the background
process to end)

  $ hg -R ../server/ admin::clone-bundles-refresh --background
  11 changesets found
  11 changesets found
  clone-bundles: starting bundle generation: v1
  clone-bundles: starting bundle generation: v2

bundles should have been generated
