context: check file exists before getting data from _wrappedctx
overlayworkingctx class is used to do in-memory merging. The data() function of
that class has logic to look for data() in the wrappedctx if the file data in
cache is empty and if the file is dirty. This assumes that if a file is dirty
and cache has empty data for it, it will exists in the _wrappedctx.
However this assumption can be False in case when we are merging a file which is
empty in destination. In these cases, the backup file 'foo.orig' created by our
internal merge algorithms will be empty, however it won't be present in
_wrappedctx. This case will lead us to error like the one this patch is fixing.
Let's only fallback to getting data from wrappedctx if cache has 'None' as data.

When they occur, it reverts *all* changes and moves forward, letting the conflict resolving patch fix collisions. Unfortunately, non-conflicting changes, like the addition of the "c" file in p1.1 patch are reverted too. Just to say that manifest not listing "c" here is a bug. $ cd .. $ hg convert darcs-repo darcs-repo-hg initializing destination darcs-repo-hg repository scanning source... sorting... converting... 4 p0 3 p1.2 2 p1.1 1 p2 0 p3 $ hg log -R darcs-repo-hg -g --template '{rev} "{desc|firstline}" ({author}) files: {files}\n' "$@" 4 "p3" (test@example.org) files: dir/d dir/d2 dir2/d f ff 3 "p2" (test@example.org) files: a dir/d dir/d2 f 2 "p1.1" (test@example.org) files: 1 "p1.2" (test@example.org) files: a b 0 "p0" (test@example.org) files: a $ hg up -q -R darcs-repo-hg $ hg -R darcs-repo-hg manifest --debug 7225b30cdf38257d5cc7780772c051b6f33e6d6b 644 a 1e88685f5ddec574a34c70af492f95b6debc8741 644 b 37406831adc447ec2385014019599dfec953c806 644 dir2/d b783a337463792a5c7d548ad85a7d3253c16ba8c 644 ff #if no-outer-repo try converting darcs1 repository $ hg clone -q "$TESTDIR/bundles/darcs1.hg" darcs $ hg convert -s darcs darcs/darcs1 2>&1 | grep darcs-1.0 darcs-1.0 repository format is unsupported, please upgrade #endif
