* Removed the i386ancient standalone tarball build for linux, which
was increasingly unable to support new git-annex features.
* Removed support for building with ghc older than 9.0.2,
and with older versions of haskell libraries than are in current Debian
stable.
* stack.yaml: Update to lts-23.2.
Note that i386ancient was targeting linux 2.6.32, which has been EOL for
over 9 years now. Any old system still using such a kernel is certainly highly
insecure. And I suspect i386ancient had its own insecurities due to haskell
libraries and C libraries not having been updated.
Turns out the %(rest) trick was not needed. Instead, just maintain a
list of files we've asked for, and each cat-file response is for the
next file in the list.
This actually benchmarks 25% faster than before! Very surprising, but it
must be due to needing to shove less data through the pipe, and parse
less.
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.
I hope this will be easier to reason about, and less buggy. It was
certianly easier to write!
An immediate benefit is that with a traversable queue of push requests to
select from, the threads can be a lot fairer about choosing which client to
service next.
