annotate tests/test-clonebundles.t @ 52316:a820a7a1fce0 default tip

setup: require TLS 1.2 support from the Python interpreter (BC)

Before it was optional, and either 1.1 or 1.2 was sufficient.  Now that the
default minimum is 1.2, it needs to be present to work out of the box.

The code here is more convoluted than the corresponding checks in `sslutil.py`,
but I'm leaving it alone because it can all be simplified when py38 is dropped.

#require no-reposimplestore no-chg

Bundle with partial content works

  $ hg -R server bundle --type gzip-v1 --base null -r 53245c60e682 partial.hg
  1 changesets found

We verify exact bundle content as an extra check against accidental future
changes. If this output changes, we could break old clients.

Bundle with full content works

Again, we perform an extra check against bundle content changes. If this content
changes, clone bundles produced by new Mercurial versions may not be readable
by old clients.

Inline bundle
=============

Checking bundle retrieved over the wireprotocol

Feature works over SSH with inline bundle
-----------------------------------------

  $ mkdir server/.hg/bundle-cache/
  $ cp full.hg server/.hg/bundle-cache/
  $ echo "peer-bundle-cache://full.hg" > server/.hg/clonebundles.manifest
  $ hg clone -U ssh://user@dummy/server ssh-inline-clone

We don't use the clone bundle, but we do not crash either.

Pre-transmit Hook
-----------------

Hooks work with inline bundle

  $ cp server/.hg/hgrc server/.hg/hgrc-beforeinlinehooks
  $ cat >> server/.hg/hgrc <<-EOF
  > [hooks]
  > pretransmit-inline-clone-bundle=sh -c 'printf "foo\n"'

Hooks can make an inline bundle fail

  $ cp server/.hg/hgrc-beforeinlinehooks server/.hg/hgrc
  $ cat >> server/.hg/hgrc <<-EOF
  > [hooks]
  > pretransmit-inline-clone-bundle=sh -c 'printf "bar\n"' && false

  $ hg clone -U ssh://user@dummy/server ssh-inline-clone-hook-fail

Testing a clone bundles that involves revlog splitting (issue6811)
==================================================================

  $ cat >> $HGRCPATH << EOF
  > [format]
  > revlog-compression=none
  > use-persistent-nodemap=no
  > EOF

  $ hg init server-revlog-split/
  $ cd server-revlog-split
  $ cat >> .hg/hgrc << EOF
  > [extensions]
  > clonebundles =
  > EOF
  $ echo foo > A
  $ hg add A
  $ hg commit -m 'initial commit'
IMPORTANT: the revlogs must not be split
  $ ls -1 .hg/store/00manifest.*
  .hg/store/00manifest.i
  $ ls -1 .hg/store/data/_a.*
  .hg/store/data/_a.i

do big enough update to split the revlogs

  $ $TESTDIR/seq.py 100000 > A
  $ mkdir foo
  $ cd foo
  $ touch `$TESTDIR/seq.py 10000`
  $ cd ..
  $ hg add -q foo
  $ hg commit -m 'split the manifest and one filelog'

IMPORTANT: now the revlogs must be split
  $ ls -1 .hg/store/00manifest.*
  .hg/store/00manifest.d
  .hg/store/00manifest.i
  $ ls -1 .hg/store/data/_a.*
  .hg/store/data/_a.d
  .hg/store/data/_a.i

Add an extra commit on top of that

  $ echo foo >> A
  $ hg commit -m 'one extra commit'

  $ cd ..

Do a bundle that contains the split, but not the update

  $ hg bundle --exact --rev '::(default~1)' -R server-revlog-split/ --type gzip-v2 split-test.hg
  2 changesets found

  $ cat > server-revlog-split/.hg/clonebundles.manifest << EOF
  > http://localhost:$HGPORT1/split-test.hg BUNDLESPEC=gzip-v2
  > EOF

start the necessary server

  $ "$PYTHON" $TESTDIR/dumbhttp.py -p $HGPORT1 --pid http.pid
  $ cat http.pid >> $DAEMON_PIDS
  $ hg -R server-revlog-split serve -d -p $HGPORT --pid-file hg.pid --accesslog access.log
  $ cat hg.pid >> $DAEMON_PIDS

Check that clone works fine
===========================

Here, the initial clone will trigger a revlog split (which is a bit clowny it
itself, but whatever). The split revlogs will see additionnal data added to
them in the subsequent pull. This should not be a problem

  $ cd revlog-split-in-the-bundle
  $ f --size .hg/store/00manifest.*
  .hg/store/00manifest.d: size=499037
  .hg/store/00manifest.i: size=192
  $ f --size .hg/store/data/_a.*

manifest should work

  $ hg  files -r tip | wc -l
  \s*10001 (re)

file content should work

  $ hg  cat -r tip A | wc -l
  \s*100001 (re)
