Now really only done in the startup scan.
It turns out to be quite hard for event handlers to know when the startup
scan is complete. I tried to make addWatch pass that info, but found
threading the state very difficult. For now, a quick hack, using the fast
flag.
Note that it's actually possible for inotify events to come in while the
startup scan is still ongoing. Due to my hack, the expensive check will
be done for files added in such inotify events.
This requires a relatively expensive test at file add time to see if it's
in git already. But it can be optimised to only happen during the startup
scan.
Remove post-copy hook 'myPostCopy': it's easy to write one based on
'myPostInst', so just wait until someone complains that it's missing.
Remove most comments.
Put long type sigs on one line like in the other source files.
The `cabal install` is happy as long as the files it needs are
present, but `cabal sdist` will only package up files you tell it to.
So, generate the source tarball ourselves.
The source tarball is generated by make-sdist.sh, which uses cabal
sdist to calculate the package name. Could also generate the name
from the 'Version:' field in git-annex.cabal.
I have a new idea: instead of the template-based approaches that work
around cabals requirement that you list all files to put in the sdist,
we can simply generate the sdist ourselves, with the files we
want. Take that cabal!
Add link CONTRIBUTING -> doc/contributing.mdwn, so that it's easy to
find (many files in doc/).
Add .dir-locals.el to .gitignore, now that it's no longer versioned.
The CONTRIBUTING file gives a reference to a page on the Emacs wiki
that shows how to set up a .dir-locals.el that sets up tabs for
indentation. I updated the wiki page to include the
`(highlight-regexp "^ *")` part, which had been the hardest to
discover.
I thought this might be a lock conflict that explains the deadlock when
built with -threaded, but it seems not.. it still locks! It even locks
without the committer thread.
Indeed, it locks when running "git annex add"! -threaded is exposing some
other problem.
Still, this seems conceptually cleaner and did not add any inneficiencies.
Also added some high-level documentation about the threads used.
The existing `sed | find | perl` hack in the Makefile was not
including the man pages in the generated git-annex.cabal. I couldn't
figure out why it didn't work; running the `find | perl` part of the
command *did* list the man pages ...
So, I set up a new hack. It produces a cleaner .cabal file and
includes the man pages in the sdist. I changed git-annex.cabal and
its generation as follows:
- git-annex.cabal is now generated by a here document in
git-annex.cabal.template.sh. The here document has inline file list
insertion, whereas before the file lists were inserted with sed.
- The 'Extra-Source-Files:' field now only includes the non-source
files: the man pages, plain text documentation, and license.
- The source dependencies are now listed in 'Other-Modules' sections
in the 'Executable' and 'Test-Suite' sections. The list of
dependencies is generated by `gen-other-modules.sh`.
- The ./debian and ./doc are no longer included in the sdist package.
These were not installed anywhere by `cabal install`. A user that
wants them could clone the git repo.
Running the tests with cabal is not yet working, i.e.
cabal configure --enable-tests && cabal build && cabal test
and
cabal install --enable-tests
fail to find Utility.Touch. However, I did not break this: it doesn't
work for the git-annex package on Hackage either. Next step is to
figure out how to deal with HSC in cabal ... or not bother, because
`make test` works. I'm worried this is a cabal bug.
To test building from sdist, I've been running
cd ../.. ; cabal sdist ; cd dist ; tar xf git-annex-3.20120605.tar.gz && cd git-annex-3.20120605 && rm -fr /tmp/git-annex && cabal install --prefix=/tmp/git-annex && tree -A /tmp/git-annex
in the dist directory. Using `cabal-dev install` is a better test,
but is very slow.
