This patch removes the "copymod" attribute from the gitpatch
class.
AFAICS, that attribute was only used to delay the copying of
renamed/copied files if there are no other changes to the target,
but in this case, if there are changes to the source, we'll end
up copying the wrong version.
This should fix issue762.
We want to store version information about the revlog in the first
entry of its index. The code in packentry was using some heuristics
to detect whether this was the first entry, but these heuristics could
fail in some cases (e.g. rev 0 was empty; rev 1 descends directly from
the nullid and is stored as a delta).
We now give the revision number to packentry to avoid heuristics.
WSGI applications are not supposed to refer to sys.stdin. In af5aceab19f4,
hgweb and hgwebdir were fixed to pass interactive=False to their ui()'s, but
sys.stdin.isatty() was still called by the ui objects. This change makes sure
only the ui.fixconfig() method will call ui.isatty() (by making the
ui._readline() method, which is currently only called from ui.prompt(),
private). ui.fixconfig() is changed to let config files override the initial
interactivity setting, but not check isatty() if interactive=False was
specified in the creation of the ui.
There are some corner cases where we may have a copy in a file that
isn't in the added list:
- the result of a hg copy --after --force
- after a merge across a (local) rename
Clearing it before the conversion protects us from whatever data were
there (file copies in particular).
Invalidating it after the conversion avoids writing a possibly
inconsistent dirstate to disk.
During a conversion, the dirstate contents are not consistent - there
are files that may be missing from the dirstate and there may be files
that shouldn't be in the dirstate.
While this is not fixed, don't mark files as added - put them directly
in state 'n'ormal.
