push: rework the computation of fallbackheads to be correct The previous computation tried to be smart but ended up being wrong. This was caught by phase movement test while reworking the phase discovery logic to be faster. The previous logic was failing to catch case where the pushed set was not based on a common heads (i.e. when the discovery seemed to have "over discovered" content, outside the pushed set) In the following graph, `e` is a common head and we `hg push -r f`. We need to detect `c` as a fallback heads and we previous failed to do so:: e | d f |/ c | b | a The performance impact of the change seems minimal. On the most impacted repository at hand (mozilla-try), the slowdown seems mostly mixed in the overall noise `hg push` but seems to be in the hundred of milliseconds order of magnitude. When using rust, we seems to be a bit faster, probably because we leverage more accelaratd internals. I added a couple of performance related common for further investigation later on.

#require unix-permissions no-root no-windows no-rhg

XXX-RHG this test hangs if `hg` is really `rhg`. This was hidden by the use of
`alias hg=rhg` by run-tests.py. With such alias removed, this test is revealed
buggy. This need to be resolved sooner than later.

repository itself is non-readable
---------------------------------

  $ hg init no-read
  $ hg id ssh://user@dummy/no-read
  000000000000
  $ chmod a-rx no-read

  $ hg id ssh://user@dummy/no-read
  remote: abort: $EACCES$: *$TESTTMP/no-read/.hg* (glob)
  abort: no suitable response from remote hg
  [255]

special case files are visible, but unreadable
----------------------------------------------

This is "similar" to the test above, but the directory is "traversable". This
seems an unexpected case in real life, but we test it anyway.

  $ hg init other
  $ hg id ssh://user@dummy/other
  000000000000
  $ for item in `find other | sort -r` ; do
  >     chmod a-r $item
  > done

  $ hg id ssh://user@dummy/other
  remote: abort: $EACCES$: '$TESTTMP/other/.hg/requires'
  abort: no suitable response from remote hg
  [255]

directory toward the repository is read only
--------------------------------------------

  $ mkdir deep
  $ hg init deep/nested

  $ hg id ssh://user@dummy/deep/nested
  000000000000

  $ chmod a-rx deep

  $ hg id ssh://user@dummy/deep/nested
  remote: abort: $EACCES$: *$TESTTMP/deep/nested/.hg* (glob)
  abort: no suitable response from remote hg
  [255]

repository has wrong requirement
--------------------------------

  $ hg init repo-future
  $ hg id ssh://user@dummy/repo-future
  000000000000
  $ echo flying-car >> repo-future/.hg/requires
  $ hg id ssh://user@dummy/repo-future
  remote: abort: repository requires features unknown to this Mercurial: flying-car
  remote: (see https://mercurial-scm.org/wiki/MissingRequirement for more information)
  abort: no suitable response from remote hg
