common commands affecting largefile.

Each sections should be independent of each others.

test for pattern matching on 'hg status':
==============================================


to boost performance, largefiles checks whether specified patterns are
related to largefiles in working directory (NOT to STANDIN) or not.

  $ hg init statusmatch
  $ cd statusmatch

  $ mkdir -p a/b/c/d
  $ echo normal > a/b/c/d/e.normal.txt
  $ hg add a/b/c/d/e.normal.txt
  $ echo large > a/b/c/d/e.large.txt
  $ hg add --large a/b/c/d/e.large.txt
  $ mkdir -p a/b/c/x
  $ echo normal > a/b/c/x/y.normal.txt
  $ hg add a/b/c/x/y.normal.txt
  $ hg commit -m 'add files'
  Invoking status precommit hook
  A a/b/c/d/e.large.txt
  A a/b/c/d/e.normal.txt
  A a/b/c/x/y.normal.txt

(1) no pattern: no performance boost
  $ hg status -A
  C a/b/c/d/e.large.txt
  C a/b/c/d/e.normal.txt
  C a/b/c/x/y.normal.txt

(2) pattern not related to largefiles: performance boost
  $ hg status -A a/b/c/x
  C a/b/c/x/y.normal.txt

(3) pattern related to largefiles: no performance boost
  $ hg status -A a/b/c/d
  C a/b/c/d/e.large.txt
  C a/b/c/d/e.normal.txt

(4) pattern related to STANDIN (not to largefiles): performance boost
  $ hg status -A .hglf/a
  C .hglf/a/b/c/d/e.large.txt

(5) mixed case: no performance boost
  $ hg status -A a/b/c/x a/b/c/d
  C a/b/c/d/e.large.txt
  C a/b/c/d/e.normal.txt
  C a/b/c/x/y.normal.txt

verify that largefiles doesn't break filesets

  $ hg log --rev . --exclude "set:binary()"

  $ hg init subrepo

  $ hg add .hgsub
  $ hg ci -m "add subrepo"

  $ hg ci -m "this commit should fail without -S"
  abort: uncommitted changes in subrepo subrepo
  (use --subrepos for recursive commit)
  [255]

Add a normal file to the subrepo, then test archiving

  $ echo 'normal file' > subrepo/normal.txt
  $ hg -R subrepo add subrepo/normal.txt

Lock in subrepo, otherwise the change isn't archived

  $ hg ci -S -m "add normal file to top level"

  Invoking status precommit hook

  A normal.txt

Test archiving a revision that references a subrepo that is not yet
cloned (see test-subrepo-recursion.t):

  $ hg clone -U . ../empty
  $ cd ../empty
  $ hg archive --subrepos -r tip ../archive.tar.gz
  cloning subrepo subrepo from $TESTTMP/statusmatch/subrepo
  $ cd ..






Test addremove, forget and others
==============================================

Test that addremove picks up largefiles prior to the initial commit (issue3541)

  $ hg init addrm2
  $ cd addrm2
  $ touch large.dat
  $ touch large2.dat
  $ touch normal
  $ hg add --large large.dat
  $ hg addremove -v
  adding large2.dat as a largefile
  adding normal

Test that forgetting all largefiles reverts to islfilesrepo() == False
(addremove will add *.dat as normal files now)
  $ hg forget large.dat
  $ hg forget large2.dat
  $ hg addremove -v
  adding large.dat
  adding large2.dat

Test commit's addremove option prior to the first commit
  $ hg forget large.dat
  $ hg forget large2.dat
  $ hg add --large large.dat
  $ hg ci -Am "commit"
  adding large2.dat as a largefile
  Invoking status precommit hook
  A large.dat
  A large2.dat
  A normal
  $ find .hglf | sort
  .hglf
  .hglf/large.dat

  $ mkdir sub
  $ cd sub
  $ echo anotherlarge > anotherlarge
  $ hg add --large anotherlarge
  $ hg st

Pusing revision #1 causes uploading entity 89e6c98d9288, which is
shared also by largefiles b1, b2 in revision #2 and b in revision #5.

Then, entity 89e6c98d9288 is not treated as "outgoing entity" at "hg
summary" and "hg outgoing", even though files in outgoing revision #2
and #5 refer it.
