8eb01bc894 Added MD5 and MD5E backends. 2015-02-04 13:47:54 -04:00

95c1593098 Remove support for building without cryptohash.
This will prevent backporting to wheezy, but it's time to simplify the
code.

4f657aa14e add getFileSize, which can get the real size of a large file on Windows
Avoid using fileSize which maxes out at just 2 gb on Windows.
Instead, use hFileSize, which doesn't have a bounded size.
Fixes support for files > 2 gb on Windows.

Note that the InodeCache code only needs to compare a file size,
so it doesn't matter it the file size wraps. So it has been
left as-is. This was necessary both to avoid invalidating existing inode
caches, and because the code passed FileStatus around and would have become
more expensive if it called getFileSize.

73928c2274 Avoid re-checksumming when migrating from hash to hashE backend. Closes: #774494 2015-01-04 12:33:10 -04:00

7b50b3c057 fix some mixed space+tab indentation
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.

9720ee9e56 testremote: New command to test uploads/downloads to a remote.
This only performs some basic tests so far; no testing of chunking or
resuming. Also, the existing encryption type of the remote is used; it
would be good later to derive an encrypted and a non-encrypted version of
the remote and test them both.

13bbb61a51 add key stability checking interface
Needed for resuming from chunks.

Url keys are considered not stable. I considered treating url keys with a
known size as stable, but just don't feel that is enough information.

bring back the (checksum) when fscking
This is useful because it shows users which files it checksums, vs ones
that are not present, or don't use a hash backend, or --fast

64160a9679 import: Add --skip-duplicates option.
Note that the hash backends were made to stop printing a (checksum..)
message as part of this, since it showed up without a file when deciding
whether to act on a file. Should have probably removed that message a while
ago anyway, I suppose.

20fb905bb6 allow building w/o cryptohash
Mostly for the debian stable autobuilds, which have a too old version
to use the Crypto.Hash module.

a05b763b01 Added SKEIN256 and SKEIN512 backends
SHA3 is still waiting for final standardization.
Although this is looking less likely given
https://www.cdt.org/blogs/joseph-lorenzo-hall/2409-nist-sha-3

In the meantime, cryptohash implements skein, and it's used by some of the
haskell ecosystem (for yesod sessions, IIRC), so this implementation is
likely to continue working. Also, I've talked with the cryprohash author
and he's a reasonable guy.

It makes sense to have an alternate high security hash, in case some
horrible attack is found against SHA2 tomorrow, or in case SHA3 comes out
and worst fears are realized.

I'd also like to support using skein for HMAC. But no hurry there and
a new version of cryptohash has much nicer HMAC code, so I will probably
wait until I can use that version.
