[darcs-devel] [patch1373] resolve issue2400

[Ben Franksen]

Ben Franksen <benjamin.franksen at helmholtz-berlin.de> added the comment:

One patch following up and improving on the one one that claims to have
resolved issue2400. The other patch is a dependency (see patch1380). I
think it makes a lot of sense to apply them all together anyway, also for
2.10.1, so no need to rebase patch1380, which is why I have obsoleted the
latter.

2 patches for repository http://darcs.net/screened:

  * resolve issue2459: fall back to writing the file if createLink fails

patch 23bad6777ea545cbf8f5d2856ab3a50d190b0f8d

  * remove race from D.R.Packs, further simplify the code
  
  It turned out cancelling the other thread makes the error only less
  probable, I could still reproduce it. The reason is that the race is
  semantically incorrect: The extra patches to fetch are not a subset of the
  ones we get from the pack, since they may contain patches that were added
  after creation of the pack.
  
  In order to further simplify the code and remove possible race conditions,
  the meta-filelist-xxx files are not written to disk. Instead we directly
  evaluate their content and pass it to fetchFilesUsingCache.
