#require serve ssl

Proper https client requires the built-in ssl from Python 2.6.

Make server certificates:

  $ CERTSDIR="$TESTDIR/sslcerts"
  $ cat "$CERTSDIR/priv.pem" "$CERTSDIR/pub.pem" >> server.pem
  $ PRIV=`pwd`/server.pem
  $ cat "$CERTSDIR/priv.pem" "$CERTSDIR/pub-not-yet.pem" > server-not-yet.pem
  $ cat "$CERTSDIR/priv.pem" "$CERTSDIR/pub-expired.pem" > server-expired.pem

  $ hg init test
  $ cd test
  $ echo foo>foo
  $ mkdir foo.d foo.d/bAr.hg.d foo.d/baR.d.hg
  $ echo foo>foo.d/foo
  $ echo bar>foo.d/bAr.hg.d/BaR
  $ echo bar>foo.d/baR.d.hg/bAR
  $ hg commit -A -m 1
  adding foo
  adding foo.d/bAr.hg.d/BaR
  adding foo.d/baR.d.hg/bAR
  adding foo.d/foo
  $ hg serve -p $HGPORT -d --pid-file=../hg0.pid --certificate=$PRIV
  $ cat ../hg0.pid >> $DAEMON_PIDS

Clients talking same TLS versions work

  $ P="$CERTSDIR" hg --config hostsecurity.minimumprotocol=tls1.0 id https://localhost:$HGPORT/
  5fed3813f7f5
  $ P="$CERTSDIR" hg --config hostsecurity.minimumprotocol=tls1.1 id https://localhost:$HGPORT1/
  5fed3813f7f5
  $ P="$CERTSDIR" hg --config hostsecurity.minimumprotocol=tls1.2 id https://localhost:$HGPORT2/
  5fed3813f7f5

Clients requiring newer TLS version than what server supports fail

  $ P="$CERTSDIR" hg id https://localhost:$HGPORT/
  (could not negotiate a common protocol; see https://mercurial-scm.org/wiki/SecureConnections for how to configure Mercurial to avoid this error)

--insecure will allow TLS 1.0 connections and override configs

  $ hg --config hostsecurity.minimumprotocol=tls1.2 id --insecure https://localhost:$HGPORT1/

The per-host config option overrides the default

  $ P="$CERTSDIR" hg id https://localhost:$HGPORT/ \
  > --config hostsecurity.minimumprotocol=tls1.2 \
  > --config hostsecurity.localhost:minimumprotocol=tls1.0
  5fed3813f7f5

The per-host config option by itself works

  $ P="$CERTSDIR" hg id https://localhost:$HGPORT/ \
  > --config hostsecurity.localhost:minimumprotocol=tls1.2
  (could not negotiate a common protocol; see https://mercurial-scm.org/wiki/SecureConnections for how to configure Mercurial to avoid this error)
