| Reorganization Question)
| 
| Hello All,
| 
| It seems to me, there were no major obstacles left unaddressed in the
| previous discussion[1] (see summary below) to merging testsuite.git into
| ghc.git.
| 
| So here's one last attempt to get testsuite.git folded into ghc.git
| before Austin branches off 7.8
| 
| Please speak up *now*, if you have any objections to folding
| testsuite.git into ghc.git *soon* (with *soon* meaning upcoming Sunday,
| 12th Jan 2014)
| 
| ----
| 
| A summary of the previous thread so far:
| 
|  - Let's fold testsuite into ghc before branching off 7.8RC
|    - ghc/testsuite have the most coupled commits
|    - make's it a bit easier to cherry pick ghc/testsuite between
| branches
|    - while being low-risk, will provide empiric value for deciding how
|      to proceed with folding in other Git repos
| 
|  - Proof of concept in
|    http://git.haskell.org/ghc.git/shortlog/refs/heads/wip/T8545
| 
|  - general support for it; consensus that it will be beneficial and
|    shouldn't be a huge disruption
| 
|  - sync-all is adapted to abort operation if `testsuite/.git` is
|    detected, and advising the user to remove (or move-out-of-the-way)
| 
|  - Concern about broken commit-refs in Trac and other places:
| 
|     - old testsuite.git repo will remain available (more or less)
|       read-only; so old commit-shas will still be resolvable
| 
|     - (old) Trac commit-links which work currently will continue to
|       work, as they refer specifically to the testsuite.git repo, and
|       Trac will know they point to the old testsuite.git
| 
|     - If one doesn't know which Git repo a commit-id is in, there's
|       still the SHA1 look-up service at http://git.haskell.org/ which
|       will search all repos hosted at git.haskell.org for a commit
|       SHA1 prefix. Or alternatively, just ask google about the SHA1.
| 
|  - Binary blobs (a few compiled executables) that were committed by
|    accident and removed right away again are removed from history to
|    avoid carrying around useless garbage in the Git history (saves
|    ~20MiB)
| 
|  - Path names are rewritten to be based in testsuite/, in order to
|    make it easier for Git operations (git log et al.) to follow
|    history for folders/filenames
| 
|  - Old Commit-ids will *not* be written into the rewritten commits'
|    messages in order not to add noise (old commit ids can be resolved
|    via the remaining old testsuite.git repo)
