setup: tweak error message for Python 3
We now have beta support for Python 3. In my opinion, it isn't
yet stable enough to allow `pip install Mercurial` to work with
Python 3 out of the box: we don't want people accidentally using
Mercurial with Python 3 just yet.
But I do think we should be more friendly about informing people
of their options.
This commit tweaks the error message that users see when running
setup.py with Python 3. We instruct them about the current level
of Python 3 support, point them at the wiki for more info, and
give them instructions on how to bypass the check.
As part of this, I also changed which version value is printed,
as we were printing a named tuple before.

#require no-windows ATTENTION: logtoprocess runs commands asynchronously. Be sure to append "| cat" to hg commands, to wait for the output, if you want to test its output. Otherwise the test will be flaky. Test if logtoprocess correctly captures command-related log calls. $ hg init $ cat > $TESTTMP/foocommand.py << EOF > from __future__ import absolute_import > from mercurial import registrar > cmdtable = {} > command = registrar.command(cmdtable) > configtable = {} > configitem = registrar.configitem(configtable) > configitem(b'logtoprocess', b'foo', > default=None, > ) > @command(b'foobar', []) > def foo(ui, repo): > ui.log(b'foo', b'a message: %s\n', b'spam') > EOF $ cp $HGRCPATH $HGRCPATH.bak $ cat >> $HGRCPATH << EOF > [extensions] > logtoprocess= > foocommand=$TESTTMP/foocommand.py > [logtoprocess] > command=(echo 'logtoprocess command output:'; > echo "\$EVENT"; > echo "\$MSG1") > $TESTTMP/command.log > commandfinish=(echo 'logtoprocess commandfinish output:'; > echo "\$EVENT"; > echo "\$MSG1"; > echo "canonical: \$OPT_CANONICAL_COMMAND") > $TESTTMP/commandfinish.log > foo=(echo 'logtoprocess foo output:'; > echo "\$EVENT"; > echo "\$MSG1") > $TESTTMP/foo.log > EOF Running a command triggers both a ui.log('command') and a ui.log('commandfinish') call. The foo command also uses ui.log. Use sort to avoid ordering issues between the various processes we spawn: $ hg fooba $ sleep 1 $ cat $TESTTMP/command.log | sort command fooba logtoprocess command output: #if no-chg $ cat $TESTTMP/commandfinish.log | sort canonical: foobar commandfinish fooba exited 0 after * seconds (glob) logtoprocess commandfinish output: $ cat $TESTTMP/foo.log | sort a message: spam foo logtoprocess foo output: #endif Confirm that logging blocked time catches stdio properly: $ cp $HGRCPATH.bak $HGRCPATH $ cat >> $HGRCPATH << EOF > [extensions] > logtoprocess= > pager= > [logtoprocess] > uiblocked=echo "\$EVENT stdio \$OPT_STDIO_BLOCKED ms command \$OPT_COMMAND_DURATION ms" > $TESTTMP/uiblocked.log > [ui] > logblockedtimes=True > EOF $ hg log $ sleep 1 $ cat $TESTTMP/uiblocked.log uiblocked stdio [0-9]+.[0-9]* ms command [0-9]+.[0-9]* ms (re) Try to confirm that pager wait on logtoprocess: Add a script that wait on a file to appears for 5 seconds, if it sees it touch another file or die after 5 seconds. If the scripts is awaited by hg, the script will die after the timeout before we could touch the file and the resulting file will not exists. If not, we will touch the file and see it. $ cat >> fakepager.py <<EOF > import sys > printed = False > for line in sys.stdin: > sys.stdout.write(line) > printed = True > if not printed: > sys.stdout.write('paged empty output!\n') > EOF $ cat > $TESTTMP/wait-output.sh << EOF > #!/bin/sh > for i in \`$TESTDIR/seq.py 50\`; do > if [ -f "$TESTTMP/wait-for-touched" ]; > then > touch "$TESTTMP/touched"; > break; > else > sleep 0.1; > fi > done > EOF $ chmod +x $TESTTMP/wait-output.sh $ cat >> $HGRCPATH << EOF > [extensions] > logtoprocess= > pager= > [pager] > pager = "$PYTHON" $TESTTMP/fakepager.py > [logtoprocess] > commandfinish=$TESTTMP/wait-output.sh > EOF $ hg version -q --pager=always Mercurial Distributed SCM (version *) (glob) $ touch $TESTTMP/wait-for-touched $ sleep 0.2 $ test -f $TESTTMP/touched && echo "SUCCESS Pager is not waiting on ltp" || echo "FAIL Pager is waiting on ltp" SUCCESS Pager is not waiting on ltp
