largefiles: synchronize lfdirstate with dirstate after automated committing Before this patch, after successful "hg rebase" of the revision removing largefiles, "hg status" may still show ""R" for such largefiles unexpectedly. "lfilesrepo.commit" executes the special code path for automated committing while rebase/transplant, and lfdirstate entries for removed files aren't updated in this code path, even after successful committing. Then, "R" entries still existing in lfdirstate cause unexpected "hg status" output. This patch synchronizes lfdirstate with dirstate after automated committing. This patch passes False as "normallookup" to "synclfdirstate", because modified files in "files()" of the recent (= just committed) context should be "normal"-ed. This is a temporary way to fix with less changes. For fundamental resolution of this kind of problems in the future, lfdirstate should be updated with dirstate simultaneously. Hooking "markcommitted" of ctx in "localrepository.commitctx" may achieve this. This problem occurs, only when (1) the parent of the working directory is rebased and (2) it removes largefiles, because: - if the parent of the working directory isn't rebased, returning to the initial revision (= update) after rebase hides this problem - files added on "other" branch (= rebase target) are treated not as "added" but as "modified" (= "normal" status and "unset" timestamp) at merging This patch tests also the status of added largefile, but it is only for avoiding regression. In addition to conditions above, "hg status" must not take existing files to reproduce this problem, because existing files make "match._files" not empty in "lfilesrepo.status" code path below: def sfindirstate(f): sf = lfutil.standin(f) dirstate = self.dirstate return sf in dirstate or sf in dirstate.dirs() match._files = [f for f in match._files if sfindirstate(f)] Not empty "match._files" prevents "status" on lfdirstate from returning the result containing problematic "R" files. This is reason why "large1" (removed) and "largeX" (added) are checked separately in this patch. Problematic code path in "lfilesrepo.commit" is used also by "hg transplant", but this problem doesn't occur at "hg transplant", because invocation of "updatelfiles" after transplant-ing in "overridetransplant" causes cleaning lfdirstate up. This patch tests also "hg transplant" as same as "hg rebase", but it is only for avoiding regression.

This file focuses mainly on updating largefiles in the working
directory (and ".hg/largefiles/dirstate")

automated commit like rebase/transplant

  $ hg commit -m '#4'

  $ hg rebase -s 1 -d 2 --keep
  $ hg status -A large1

  $ hg update -q -C 2
  $ hg transplant -q 1 4
  $ hg status -A large1

  $ hg status -A largeX

  $ hg update -q -C 2
  $ hg transplant -q --merge 1 --merge 4
  $ hg status -A large1
