posix: give checkexec a fast path; keep the check files and test read only

Before, Mercurial would create a new temporary file every time, stat it, change
its exec mode, stat it again, and delete it. Most of this dance was done to
handle the rare and not-so-essential case of VFAT mounts on unix. The cost of
that was paid by the much more common and important case of using normal file
systems.

Instead, try to create and preserve .hg/cache/checkisexec and
.hg/cache/checknoexec with and without exec flag set. If the files exist and
have correct exec flags set, we can conclude that that file system supports the
exec flag. Best case, the whole exec check can thus be done with two stat
calls. Worst case, we delete the wrong files and check as usual. That will be
because temporary loss of exec bit or on file systems without support for the
exec bit. In that case we check as we did before, with the additional overhead
of one extra stat call.

It is possible that this different test algorithm in some cases on odd file
systems will give different behaviour. Again, I think it will be rare and
special cases and I think it is worth the risk.

test-clone.t happens to show the situation where checkisexec is left behind
from the old style check, while checknoexec only will be created next time a
exec check will be performed.

  $ hg init a

  $ echo a > a/a
  $ hg --cwd a ci -Ama
  adding a

  $ hg clone a c
  updating to branch default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ hg clone a b
  updating to branch default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ echo b >> b/a
  $ hg --cwd b ci -mb

Push should provide a hint when both 'default' and 'default-push' not set:
  $ cd c
  $ hg push --config paths.default=
  abort: default repository not configured!
  (see 'hg help config.paths')
  [255]

  $ cd ..

Push should push to 'default' when 'default-push' not set:

  $ hg --cwd b push
  pushing to $TESTTMP/a (glob)
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files

Push should push to 'default-push' when set:

  $ echo '[paths]' >> b/.hg/hgrc
  $ echo 'default-push = ../c' >> b/.hg/hgrc
  $ hg --cwd b push
  pushing to $TESTTMP/c (glob)
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files

But push should push to 'default' if explicitly specified (issue5000):

  $ hg --cwd b push default
  pushing to $TESTTMP/a (glob)
  searching for changes
  no changes found
  [1]

Push should push to 'default-push' when 'default' is not set

  $ hg -q clone a push-default-only
  $ cd push-default-only
  $ rm .hg/hgrc

  $ touch foo
  $ hg -q commit -A -m 'add foo'
  $ hg --config paths.default-push=../a push
  pushing to $TESTTMP/a (glob)
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files

  $ cd ..

Pushing to a path that isn't defined should not fall back to default

  $ hg --cwd b push doesnotexist
  abort: repository doesnotexist does not exist!
  [255]

:pushurl is used when defined

  $ hg -q clone a pushurlsource
  $ hg -q clone a pushurldest
  $ cd pushurlsource

Windows needs a leading slash to make a URL that passes all of the checks
  $ WD=`pwd`
#if windows
  $ WD="/$WD"
#endif
  $ cat > .hg/hgrc << EOF
  > [paths]
  > default = https://example.com/not/relevant
  > default:pushurl = file://$WD/../pushurldest
  > EOF

  $ touch pushurl
  $ hg -q commit -A -m 'add pushurl'
  $ hg push
  pushing to file:/*/$TESTTMP/pushurlsource/../pushurldest (glob)
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files

:pushrev is used when no -r is passed

  $ cat >> .hg/hgrc << EOF
  > default:pushrev = .
  > EOF
  $ hg -q up -r 0
  $ echo head1 > foo
  $ hg -q commit -A -m head1
  $ hg -q up -r 0
  $ echo head2 > foo
  $ hg -q commit -A -m head2
  $ hg push -f
  pushing to file:/*/$TESTTMP/pushurlsource/../pushurldest (glob)
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files (+1 heads)

  $ hg --config 'paths.default:pushrev=draft()' push -f
  pushing to file:/*/$TESTTMP/pushurlsource/../pushurldest (glob)
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files (+1 heads)

Invalid :pushrev raises appropriately

  $ hg --config 'paths.default:pushrev=notdefined()' push
  pushing to file:/*/$TESTTMP/pushurlsource/../pushurldest (glob)
  hg: parse error: unknown identifier: notdefined
  [255]

  $ hg --config 'paths.default:pushrev=(' push
  pushing to file:/*/$TESTTMP/pushurlsource/../pushurldest (glob)
  hg: parse error at 1: not a prefix: end
  [255]

  $ cd ..
