* Fix bug in combination of preferred and required content settings. When one ↵Gravatar Joey Hess2015-09-15
| | | | | | | was set to the empty string and the other set to some expression, this bug caused all files to be wanted, instead of only files matching the expression. Avoid: MAny `MOr` otherexpression Which matches anything.

* fix some mixed space+tab indentationGravatar Joey Hess2014-10-09
| | | | | | | | | This fixes all instances of " \t" in the code base. Most common case seems to be after a "where" line; probably vim copied the two space layout of that line. Done as a background task while listening to episode 2 of the Type Theory podcast.
* unify exception handling into Utility.ExceptionGravatar Joey Hess2014-08-07
| | | | | | | | | | | | | | | | | | | | Removed old extensible-exceptions, only needed for very old ghc. Made webdav use Utility.Exception, to work after some changes in DAV's exception handling. Removed Annex.Exception. Mostly this was trivial, but note that tryAnnex is replaced with tryNonAsync and catchAnnex replaced with catchNonAsync. In theory that could be a behavior change, since the former caught all exceptions, and the latter don't catch async exceptions. However, in practice, nothing in the Annex monad uses async exceptions. Grepping for throwTo and killThread only find stuff in the assistant, which does not seem related. Command.Add.undo is changed to accept a SomeException, and things that use it for rollback now catch non-async exceptions, rather than only IOExceptions.

* Added required content configuration.Gravatar Joey Hess2014-03-29
| | | | | | | This includes checking when dropping files that any required content configuration is satisfied. However, it does not yet include an active check on the required content; the location log is trusted when checking the required content expression.

* Fix bug in parsing of parens in some preferred content expressions. This ↵Gravatar Joey Hess2013-05-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fixes the behavior of the manual mode group. The current manual mode preferred content expression is: "present and (((exclude=*/archive/* and exclude=archive/*) or (not (copies=archive:1 or copies=smallarchive:1))) or (not copies=semitrusted+:1))" The old matcher misparsed this, to basically: OR (present and (...)) (not copies=semitrusted+:1)) The paren handling and indeed the whole conversion from tokens to the matcher was just wrong. The new way may not be the cleverest, but I think it is correct, and you can see how it pattern matches structurally against the expressions when parsing them. That expression is now parsed to: MAnd (MOp <function>) (MOr (MOr (MAnd (MOp <function>) (MOp <function>)) (MNot (MOr (MOp <function>) (MOp <function>)))) (MNot (MOp <function>))) Which appears correct, and behaves correct in testing. Also threw in a simplifier, so the final generated Matcher has less unnecessary clutter in it. Mostly so that I could more easily read & confirm them. Also, added a simple test of the Matcher to the test suite. There is a small chance of badly formed preferred content expressions behaving differently than before due to this rewrite.

* --auto fixesGravatar Joey Hess2012-12-06
| | | | | | | * get/copy --auto: Transfer data even if it would exceed numcopies, when preferred content settings want it. * drop --auto: Fix dropping content when there are no preferred content settings.
* avoid duplicate code with a more generic monadic matcherGravatar Joey Hess2012-10-13
| | | | | Interesting type signature ghc derived for this: forall o (m :: * -> *). Monad m => Matcher o -> (o -> m Bool) -> m Bool
* wired preferred content up to get, copy, and drop --autoGravatar Joey Hess2012-10-08

* added preferred-content log, and allow editing it with vicfgGravatar Joey Hess2012-10-04
| | | | | | | | | | | | | | This includes a full parser for the boolean expressions in the log, that compiles them into Matchers. Those matchers are not used yet. A complication is that matching against an expression should never crash git-annex with an error. Instead, vicfg checks that the expressions parse. If a bad expression (or an expression understood by some future git-annex version) gets into the log, it'll be ignored. Most of the code in Limit couldn't fail anyway, but I did have to make limitCopies check its parameter first, and return an error if it's bad, rather than erroring at runtime.
* fun with symbolsGravatar Joey Hess2012-03-17
| | | | | | Nothing at all on hackage is using <&&> or <||>. (Also, <&&> should short-circuit on failure.)
* optimize monadic ||Gravatar Joey Hess2012-03-16
| | | | | (||) used applicative style runs both conditions rather than short circuiting. Add an orM that properly short-circuits.

| | | | | | | | | find: Rather than only showing files whose contents are present, when used with --exclude --copies or --in, displays all files that match the specified conditions. Note that this is a behavior change for find --exclude! Old behavior can be gotten with find --in . --exclude=...
