streamclone: force @filecache properties to be reloaded from file Before this patch, consumev1() invokes repo.invalidate() after closing transaction, to force @filecache properties to be reloaded from files at next access, because streamclone writes data into files directly. But this doesn't work as expected in the case below: 1. at closing transaction, repo._refreshfilecachestats() refreshes file stat of each @filecache properties with streamclone-ed files This means that in-memory properties are treated as valid. 2. but streamclone doesn't changes in-memory properties This means that in-memory properties are actually invalid. 3. repo.invalidate() just forces to examine file stat of @filecache properties at the first access after it Such examination should concludes that reloading from file isn't needed, because file stat was already refreshed at (1). Therefore, invalid in-memory cached properties (2) are unintentionally treated as valid (1). This patch invokes repo.invalidate() with clearfilecache=True, to force @filecache properties to be reloaded from file at next access. BTW, it is accidental that repo.invalidate() without clearfilecache=True in streamclone case seems to work as expected before this patch. If transaction is started via "filtered repo" object, repo._refreshfilecachestats() tries to refresh file stat of each @filecache properties on "filtered repo" object, even though all of them are stored into "unfiltered repo" object. In this case, repo._refreshfilecachestats() does nothing unintentionally, but this unexpected behavior causes reloading @filecache properties after repo.invalidate(). This is reason why this patch should be applied before making _refreshfilecachestats() correctly refresh file stat of @filecache properties.

Set up a base, local, and remote changeset, as well as the working copy state.
Files names are of the form base_remote_local_working-copy. For example,
content1_content2_content1_content2-untracked represents a
file that was modified in the remote changeset, left untouched in the
local changeset, and then modified in the working copy to match the
remote content, then finally forgotten.

  $ hg init repo
  $ cd repo

Create base changeset

  $ python $TESTDIR/generate-working-copy-states.py state 3 1
  $ hg addremove -q --similarity 0
  $ hg commit -qm 'base'

Create remote changeset

  $ python $TESTDIR/generate-working-copy-states.py state 3 2
  $ hg addremove -q --similarity 0
  $ hg commit -qm 'remote'

Create local changeset

  $ hg update -q 0
  $ python $TESTDIR/generate-working-copy-states.py state 3 3
  $ hg addremove -q --similarity 0
  $ hg commit -qm 'local'

Set up working directory

  $ python $TESTDIR/generate-working-copy-states.py state 3 wc

Check which files need to be resolved (should correspond to the output above).
This should be the files for which the base (1st filename segment), the remote
(2nd segment) and the working copy (4th segment) are all different.

Interestingly, one untracked file got merged and added, which corresponds to the
odd 'if force and branchmerge and different' case in manifestmerge().

Check status and file content

Some files get added (e.g. content1_content2_content1_content1-untracked)

It is not intuitive that content1_content2_content1_content4-tracked gets
merged while content1_content2_content1_content4-untracked gets overwritten.
Any *_content2_*-untracked triggers the modified/deleted prompt and then gets
overwritten.

A lot of untracked files become tracked, for example
content1_content2_content2_content2-untracked.

*_missing_missing_missing-tracked is reported as removed ('R'), which
doesn't make sense since the file did not exist in the parent, but on the
other hand, merged-in additions are reported as modifications, which is
almost as strange.

missing_missing_content3_missing-tracked becomes removed ('R'), even though
the remote side did not touch the file
