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

In ab70693 @viric says zsnes works better without stripping. But the
build expression kept the $STRIP in the compiler options, so if it is
set to something it will show up in there. For example:
g++ -pipe -I. -I/usr/local/include -I/usr/include -D__UNIXSDL__ -I/nix/store/04qgmdpmalgsy92zgs2z896jx073hcn2-SDL-1.2.15-dev/include/SDL -I/nix/store/04qgmdpmalgsy92zgs2z896jx073hcn2-SDL-1.2.15-dev/include/SDL -D_GNU_SOURCE=1 -D_REENTRANT -DNCURSES -D__OPENGL__ -march=native -O3 -fomit-frame-pointer -fprefetch-loop-arrays -fforce-addr strip -D__RELEASE__ -fno-rtti -o tools/fileutil.o -c tools/fileutil.cpp
g++: error: strip: No such file or directory
This commit removes that reference to $STRIP too.
Fixes#27906
Because #pragma GCC optimize ("O0") doesn't work for clang and
NIX_CFLAGS_COMPILE bypasses the fixup done by the makefiles everything
gets compiled with -O2.
The build still uses optimisation for everything else.
The build was failing due to missing telepathy_logger dependency,
I added it. Additionally, the connection to server was failing due to
telepathy executables not having an access to dconf, which was fixed
in #26113. Lastly, when I tried running Polari directly, it terminated
with SIGTRAP and the following error:
(org.gnome.Polari:22998): GLib-GIO-ERROR **: Settings schema 'org.gnome.desktop.interface' is not installed
adding `gnome3.gsettings_desktop_schemas` as a buildInput fixed that.
Some programs store the executable in a different place and link it
from the `bin` directory. For example, Polari links `$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.
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.
This adds a convenient per-peer option to set the routing table that associated routes are added to. This functionality is very useful for isolating interfaces from the kernel's global routing and forcing all traffic of a virtual interface (or a group of processes, via e.g. "ip rule add uidrange 10000-10009 lookup 42") through Wireguard.
