ancestor.deepest: decrement ninteresting correctly (issue3984)
The invariant this code tries to hold is that ninteresting is the number of
non-zero elements in the interesting array. interesting[nsp] is incremented at
the same time as interesting[sp] is decremented. So if interesting[nsp] was
previously 0, ninteresting shouldn't be decremented.
Mercurial's internal web server, hgweb, can serve either a single
repository, or a tree of repositories. In the second case, repository
paths and global options can be defined using a dedicated
configuration file common to :hg:`serve`, ``hgweb.wsgi``,
``hgweb.cgi`` and ``hgweb.fcgi``.
This file uses the same syntax as other Mercurial configuration files
but recognizes only the following sections:
- web
- paths
- collections
The ``web`` options are thoroughly described in :hg:`help config`.
The ``paths`` section maps URL paths to paths of repositories in the
filesystem. hgweb will not expose the filesystem directly - only
Mercurial repositories can be published and only according to the
configuration.
The left hand side is the path in the URL. Note that hgweb reserves
subpaths like ``rev`` or ``file``, try using different names for
nested repositories to avoid confusing effects.
The right hand side is the path in the filesystem. If the specified
path ends with ``*`` or ``**`` the filesystem will be searched
recursively for repositories below that point.
With ``*`` it will not recurse into the repositories it finds (except for
``.hg/patches``).
With ``**`` it will also search inside repository working directories
and possibly find subrepositories.
In this example::
[paths]
/projects/a = /srv/tmprepos/a
/projects/b = c:/repos/b
/ = /srv/repos/*
/user/bob = /home/bob/repos/**
- The first two entries make two repositories in different directories
appear under the same directory in the web interface
- The third entry will publish every Mercurial repository found in
``/srv/repos/``, for instance the repository ``/srv/repos/quux/``
will appear as ``http://server/quux/``
- The fourth entry will publish both ``http://server/user/bob/quux/``
and ``http://server/user/bob/quux/testsubrepo/``
The ``collections`` section is deprecated and has been superseded by
``paths``.
