largefiles: handle commit -A properly, after a --large commit (issue3542) Previous to this, 'commit -A' would add as normal files, files that were already committed as largefiles, resulting in files being listed twice by 'status -A'. It also missed when (only) a largefile was deleted, even though status reported it as '!'. This also has the side effect of properly reporting the state of the affected largefiles in the post commit hook after a remove that also affected a normal file (the largefiles used to be 'R', now are properly absent). Since scmutil.addremove() is called both by the ui command (after some trivial argument validation) and during the commit process when -A is specified, it seems like a more appropriate method to wrap than the addremove command. Currently, a repo is only enabled to use largefiles after an add that explicitly identifies some file as large, and a subsequent commit. Therefore, this patch only changes behavior after such a largefile enabling commit. Note that in the test, if the final commit had a '-v', 'removing large8' would be printed twice. Both of these originate in removelargefiles(). The first print is in verbose mode after traversing remove + forget, the second is because the '_isaddremove' attr is set and 'after' is not.

Create extension that can disable symlink support:

  $ cat > nolink.py <<EOF
  > from mercurial import extensions, util
  > def setflags(orig, f, l, x):
  >     pass
  > def checklink(orig, path):
  >     return False
  > def extsetup(ui):
  >     extensions.wrapfunction(util, 'setflags', setflags)
  >     extensions.wrapfunction(util, 'checklink', checklink)
  > EOF

  $ hg init unix-repo
  $ cd unix-repo
  $ echo foo > a
  $ ln -s a b
  $ hg ci -Am0
  adding a
  adding b
  $ cd ..

Simulate a checkout shared on NFS/Samba:

  $ hg clone -q unix-repo shared
  $ cd shared
  $ rm b
  $ echo foo > b
  $ hg --config extensions.n=$TESTTMP/nolink.py status --debug
  ignoring suspect symlink placeholder "b"

Make a clone using placeholders:

  $ hg --config extensions.n=$TESTTMP/nolink.py clone . ../win-repo
  updating to branch default
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd ../win-repo
  $ cat b
  a (no-eol)
  $ hg --config extensions.n=$TESTTMP/nolink.py st --debug

Write binary data to the placeholder:

  >>> open('b', 'w').write('this is a binary\0')
  $ hg --config extensions.n=$TESTTMP/nolink.py st --debug
  ignoring suspect symlink placeholder "b"

Write a long string to the placeholder:

  >>> open('b', 'w').write('this' * 1000)
  $ hg --config extensions.n=$TESTTMP/nolink.py st --debug
  ignoring suspect symlink placeholder "b"

Commit shouldn't succeed:

  $ hg --config extensions.n=$TESTTMP/nolink.py ci -m1
  nothing changed
  [1]

Write a valid string to the placeholder:

  >>> open('b', 'w').write('this')
  $ hg --config extensions.n=$TESTTMP/nolink.py st --debug
  M b
  $ hg --config extensions.n=$TESTTMP/nolink.py ci -m1
  $ hg manifest tip --verbose
  644   a
  644 @ b

  $ cd ..
