This reduces diffoscope's closure size from 2470 MiB to 579 MiB by
leaving out some less crucial dependencies (like GHC and Free
Pascal). These can be re-enabled by turning on enableBloat.
This will eventually become the new stable branch (as unstable ones
are wont to do), but is worth having if you want to patch yesterday's
‘large’ files today, or need to apply patches already created with it.
“First release of the 3.1.x series. This is taken from the
"64bithash" branch.
- Adds support for -B values greater than 2GB, enabled by
-DXD3_USE_LARGESIZET=1 variable. [Enabled in nixpkgs.]
- Adds new performance and speed regression test, written in #Golang.
[Not enabled in nixpkgs.]
When compiled for large sizes, xdelta3 uses a 64bit checksum function.
This impacts both compression and speed.
Relative to 3.0.11, the new branch is currently 3-5% slower and
has 1-2% worse compression. Performance will be addressed in
future 3.1.x releases.”
Before executing the gnuplot executable the environment variable `GDFONTPATH`
is populated with a list of font directories, which is obtained from `fc-list`.
In that process we iterated over each line and called `dirname` on it, which
introduces a performance hit for loading and executing the external executable
`dirname` every time.
The new version avoids the loop.
The author of this patch measured a 42 fold performance improvement:
old version:
$ time ./gnuplot_old/bin/gnuplot -e ''
real 0m3.828s
user 0m0.392s
sys 0m0.465s
new version:
$ time ./gnuplot_new2/bin/gnuplot -e ''
real 0m0.091s
user 0m0.112s
sys 0m0.014s
The correctness of the value of `GDFONTPATH` was confirmed with the following
command and comparing its output between versions:
$ gnuplot -e 'print system("echo $GDFONTPATH")'
Broken since Aug 2015, but upstream has been dead for donkey's
years. Only dependent was systemtap. No reasonable way (or indeed
reason) to artificially keep this alive.
Aim for the head.
additional changes:
- tmate now depends on external libmsgpack and libssh
- postPatch is no longer useful as it applied to embedded msgpack
- regular automake can now be used
‘When upgrading to 0.29.0 you need to upgrade client as well as server
installations due to the locking and commandline interface changes
otherwise you’ll get an error msg about a RPC protocol mismatch or a
wrong commandline option. if you run a server that needs to support both
old and new clients, it is suggested that you have a “borg-0.28.2” and a
“borg-0.29.0” command. clients then can choose via e.g. “borg
–remote-path=borg-0.29.0 ...”.’
‘The default waiting time for a lock changed from infinity to 1 second
for a better interactive user experience. if the repo you want to access
is currently locked, borg will now terminate after 1s with an error
message. if you have scripts that shall wait for the lock for a longer
time, use –lock-wait N (with N being the maximum wait time in seconds).’

This patch is borrowed verbatim from Debian, where it is actively
maintained for each openssh update. It's also included in Fedora's
openssh package, in Arch linux as openssh-gssapi in the AUR, in MacOS
X, and presumably various other platforms and linux distros.
The main relevant parts of this patch:
- Adds several ssh_config options:
GSSAPIKeyExchange, GSSAPITrustDNS,
GSSAPIClientIdentity, GSSAPIServerIdentity
GSSAPIRenewalForcesRekey
- Optionally use an in-memory credentials cache api for security
My primary motivation for wanting the patch is the GSSAPIKeyExchange
and GSSAPITrustDNS features. My user ssh_config is shared across
several OSes, and it's a lot easier to manage if they all support the
same options.
added tldr to all-packages.nix
cleaned up style
added metadata
semicolons
didn't test on mac. removed platform
wrong types
fixed duplication of version
Currently the package is built with /var in $out/var. That fails when it
tries to create/write things at runtime (nix store is read-only).
Instead, tell it to use /var (global directory) and fixup the
installation phase so it doesn't touch /var (leave that for runtime).
This unbreaks the colord dbus service, which apparently is needed by
cups to create color profiles for printers.
Otherwise it will try to guess the log directory, and the guess might
not be the same if chroot builds are enabled or not.
