  created new head

Test that update also updates the lfdirstate of 'unsure' largefiles after

hashing them:

The previous operations will usually have left us with largefiles with a mtime

within the same second as the dirstate was written.

The lfdirstate entries will thus have been written with an invalidated/unset

mtime to make sure further changes within the same second is detected.

We will however occasionally be "lucky" and get a tick between writing

largefiles and writing dirstate so we get valid lfdirstate timestamps. The

following verification is thus disabled but can be verified manually.

#if false

  $ hg debugdirstate --large --nodate

  n 644          7 unset               large1

  n 644         13 unset               large2

#endif

Wait to make sure we get a tick so the mtime of the largefiles become valid.

  $ sleep 1

A linear merge will update standins before performing the actual merge. It will

do a lfdirstate status walk and find 'unset'/'unsure' files, hash them, and

update the corresponding standins.

Verify that it actually marks the clean files as clean in lfdirstate so

we don't have to hash them again next time we update.

  $ hg up

  0 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ hg debugdirstate --large --nodate

  n 644          7 set                 large1

  n 644         13 set                 large2

Test that lfdirstate keeps track of last modification of largefiles and

prevents unnecessary hashing of content - also after linear/noop update

  $ sleep 1

  $ hg st

  $ hg debugdirstate --large --nodate

  n 644          7 set                 large1

  n 644         13 set                 large2
