* Removed the webapp-secure build flag, rolling it into the webapp build
flag.
* Removed the quvi and tahoe build flags, which only adds aeson to
the core dependencies.
* Removed the feed build flag, which only adds feed to the core
dependencies.
Build flags have cost in both code complexity and also make Setup configure
have to work harder to find a usable set of build flags when some
dependencies are missing.
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 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.
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.
This version of wai changed the type of Middleware, so I cannot seem
to liftIO inside it. So, got rid of a lot of not really needed
complexity to use System.Log.Logger's logging stuff, and just use
the standard wai stdout logger when debug logging is enabled.
Format may change some, and it logs http to stdout instead of stderr
now. Doesn't matter for the webapp since both go to the same log anyway.
Motivation: Hook scripts for nautilus or other file managers
need to provide the user with feedback that a file is being downloaded.
This commit was sponsored by THM Schoemaker.
Debian stable's warp-tls is too old to support the new https feature well,
so only use http with that old version.
Note that the webapp still depends on warp-tls, because the TLSSettings
type is used.
This is a massive win on OSX, which doesn't have a sha256sum normally.
Only use external hash commands when the file is > 1 mb,
since cryptohash is quite close to them in speed.
SHA is still used to calculate HMACs. I don't quite understand
cryptohash's API for those.
Used the following benchmark to arrive at the 1 mb number.
1 mb file:
benchmarking sha256/internal
mean: 13.86696 ms, lb 13.83010 ms, ub 13.93453 ms, ci 0.950
std dev: 249.3235 us, lb 162.0448 us, ub 458.1744 us, ci 0.950
found 5 outliers among 100 samples (5.0%)
4 (4.0%) high mild
1 (1.0%) high severe
variance introduced by outliers: 10.415%
variance is moderately inflated by outliers

For an unknown reason, getAddrInfo currently is segfaulting. Note that
in February, I had used warpDebug, which uses getAddrInfo, and it worked.
Don't know if my toolchain has changed and broke it, or it's due to having
a different Android device now. Anyway, work around it by hardcoding the
address to use.
This caused the code to fail on Android, which doesn't know that flag.
It seems best to let the OS default flags be used. Tested working ok on
Linux. The only difference on Linux is it might return a v4mapped ipv6
address sometimes.
It used to not log to daemon.log when a repository was first created, and
when starting the webapp. Now both do. Redirecting stdout and stderr to the
log is tricky when starting the webapp, because the web browser may want to
communicate with the user. (Either a console web browser, or web.browser = echo)
This is handled by restoring the original fds when running the browser.
since some systems may have configuration problems or other issues that
prevent web browsers from connecting to the right localhost IP for the
webapp.
Tested on both ipv4 and ipv6 localhost. Url for the latter looks like:
http://[::1]:50676
