The flockit library and tool exists solely because rsync doesn't have file
locking.
It's not used like a normal library; you don't link against it, and you don't
have to patch your source code to use it. It's inserted between your program and
its libraries by use of LD_PRELOAD.
For example:
$ env LD_PRELOAD=$(nix-build -A pkgs.flockit)/lib/libflockit.so FLOCKIT_FILE_PREFIX=test rsync SRC DEST
Besides the library a handy executable is provided which can simplify the above to:
$ $(nix-build -A pkgs.flockit)/bin/flockit test rsync SRC DEST

Fixes#27906
Because #pragma GCC optimize ("O0") doesn't work for clang and
NIX_CFLAGS_COMPILE bypasses the fixup done by the makefiles everything
gets compiled with -O2.
The build still uses optimisation for everything else.
The build was failing due to missing telepathy_logger dependency,
I added it. Additionally, the connection to server was failing due to
telepathy executables not having an access to dconf, which was fixed
in #26113. Lastly, when I tried running Polari directly, it terminated
with SIGTRAP and the following error:
(org.gnome.Polari:22998): GLib-GIO-ERROR **: Settings schema 'org.gnome.desktop.interface' is not installed
adding `gnome3.gsettings_desktop_schemas` as a buildInput fixed that.
Some programs store the executable in a different place and link it
from the `bin` directory. For example, Polari links `$out/bin/polari`
to `$out/share/polari/org.gnome.Polari`. `wrapGAppsHook` did not follow
symlinks so it was not able to wrap Polari, making it unable to access
GObject introspection definitions required for running the program.
I made the wrapping script follow symlinks to fix this corner case.
This updates to the new runc as was also done upstream:
f3ef17e47d
In particular, it fixes an issue where output of interactive docker containers
would not reset correctly to the beginning of a line.
The versions of Coq available through this expression do not actually
require camlp5_transitional. We drop this dependency to see if, in the
future, the package camlp5_transitional can be removed from nixpkgs.
