It was failing at link time, some problem with terminatePID.
Re-implemented that to not use a C wrapper function, which cleared up the
problem. Removed old EvilLinker hack with must have been related to the
same problem.
Note that I have not tested this with older ghc's. In
f11f7520b5 I mention having tried this
approach before, and getting segfaults.. So, who knows. It seems to work
fine with ghc 7.10 at least.
This is mostly to be able to see how long a command took to run. Also exit
code may be useful.
Unofrtunately, I can't put the command name in there, because it's not
available at this point, and it would be a much larger change to wrap the
ProcessHandle data type to add that. However, it's generally pretty obvious
which process exited from context.
Since _encodeFilePath generates a String that doesn't use the filesystem
encoding, when this exception is caught, we know we already have such a
String, and can just return it as-is.
This was caused by 23e9d3bb77
an Arbitrary String is not necessarily encoded using the filesystem
encoding, and in a non-utf8 locale, encodeBS throws an exception on such a
string. All I could think to do is limit test data to ascii.
This shouldn't be a problem in practice, because the all Strings in
git-annex that are not generated by Arbitrary should be loaded in a way
that does apply the filesystem encoding.
Oh boy, not again. So, another place that the filesystem encoding needs to
be applied. Yay.
In passing, I changed decodeBS so if a NUL is embedded in the input, the
resulting FilePath doesn't get truncated at that NUL. This was needed to
make prop_b64_roundtrips pass, and on reviewing the callers of decodeBS, I
didn't see any where this wouldn't make sense. When a FilePath is used to
operate on the filesystem, it'll get truncated at a NUL anyway, whereas if
a String is being used for something else, it might conceivably have a NUL
in it, and we wouldn't want it to get truncated when going through
decodeBS.
(NB: There may be a speed impact from this change.)
While cryptohash has SHA3 support, it has not been updated for the final
version of the spec. Note that cryptonite has not been ported to all arches
that cryptohash builds on yet.
This fixes a reversion introduced by relative path changes back last winter.
The root cause is simplifyPath "../foo" was incorrectly yielding "foo".
absPathFrom seems quite horrible. Probably most things that use it should
use </> instead.
This is needed because when preferred content matches on files,
the second pass would otherwise want to drop all keys. Using a bloom filter
avoids this, and in the case of a false positive, a key will be left
undropped that preferred content would allow dropping. Chances of that
happening are a mere 1 in 1 million.
I want this as fast as possible, so it can be added to code paths without
slowing them down.
Avoid the set lookup, and rely on laziness,
drops runtime from 14.37 ns to 11.03 ns according to this criterion benchmark:
import Criterion.Main
import qualified Types.Difference as New
import qualified Types.DifferenceOld as Old
main :: IO ()
main = defaultMain
[ bgroup "hasDifference"
[ bench "new" $ whnf (New.hasDifference New.OneLevelObjectHash) new
, bench "old" $ whnf (Old.hasDifference Old.OneLevelObjectHash) old
]
]
where
s = "fromList [ObjectHashLower, OneLevelObjectHash, OneLevelBranchHash]"
new = New.readDifferences s
old = Old.readDifferences s
A little bit of added boilerplate, but I suppose it's worth it to not
need to worry about set lookup overhead. Note that adding more differences
would slow down the old implementation; the new implementation will run
the same speed.
This reverts commit ef0e3ac22e.
Sebastian thinks best to revert this:
It seems to me the reason I needed to look at activatable sockets
might actually be a networkd bug, and I was in error about patch 0001.
On my machines (without DHCP), networkd quits after configuring the
links. I thought this had to do with network activation, but that was
probably mistaken. This was obscured by my testing the change by doing
systemctl stop/start on networkd; now that I actually unplugged the
network cable, I noticed no DBus messages are triggered by this on
this machine. Your test case might have had a similar problem
(networkd quitting on idle). Might be related to [1].
On another machine (with DHCP) networkd remains active all the time,
and patch 0002 works there. You might want to revert 0001, though:
Suppose someone’s running no manager at all, so that polling would be
required. Because networkd is still listed as activable, we would
refrain from polling – by mistake, because networkd doesn’t seem to
actually go active if we listen on its bus, and it’s listed as
activable even when it’s not configured. Connectivity-related messages
will come in when stopping/starting the service, but not when
unplugging the cable.
This removes a bit of complexity, and should make things faster
(avoids tokenizing Params string), and probably involve less garbage
collection.
In a few places, it was useful to use Params to avoid needing a list,
but that is easily avoided.
Problems noticed while doing this conversion:
* Some uses of Params "oneword" which was entirely unnecessary
overhead.
* A few places that built up a list of parameters with ++
and then used Params to split it!
Test suite passes.
The content file may not be owned by the user running git-annex, in which
case, setting the owner write bit was not enough to let lockContent
act on the file. However, with some core.sharedRepository configs, the file
should be writable by the user's group. So, the thing to do is to call
thawContent on it.
Also cleaned up the code, avoiding creating a lock file if we're going to
open it for create later anyway.
And, if there's an exception while preparing to lock the file, but not at
the point of actually taking the lock, throw an exception, instead of
silently not locking and pretending to succeed.
And, on Windows, always use lock file, even if the repo somehow got into
indirect mode (maybe with cygwin git..)
The one exception is in Utility.Daemon. As long as a process only
daemonizes once, which seems reasonable, and as long as it avoids calling
checkDaemon once it's already running as a daemon, the fcntl locking
gotchas won't be a problem there.
Annex.LockFile has it's own separate lock pool layer, which has been
renamed to LockCache. This is a persistent cache of locks that persist
until closed.
This is not quite done; lockContent stil needs to be converted.
