When compiling natively (target=#f in Guix parlance), this is perfectly fine. However, when cross-compiling, there is a problem. "which" looks in $PATH for binaries. That's good for purpose (1), but incorrect for (2), as the $PATH contains binaries from native-inputs instead of inputs. This commit defines a ‘search-input-file’ procedure. It functions like 'which', but instead of searching in $PATH, it searches in the 'inputs' of the build phase, which must be passed to ‘search-input-file’ as an argument. Also, the file name must include "bin/" or "sbin/" as appropriate. * guix/build/utils.scm (search-input-file): New procedure. * tests/build-utils.scm ("search-input-file: exception if not found") ("search-input-file: can find if existent"): Test it. * doc/guix.texi (File Search): Document it.

Before this change, the presence of a NUL character on a line meant that the (glibc) regexp engine used by Guile would either 1. stop scanning the string or 2. crash with the error "string contains #\\nul character", depending on the locale used. This change works around this limitation by first replacing the NUL character by an unused Unicode code point, doing the substitution, then reverting the replacement. * guix/build/utils.scm (unused-private-use-code-point) (replace-char): New procedures. (substitute): Make use of the above procedures to work around the NUL character regexp engine limitation. * tests/build-utils.scm: Add tests.

Reported by Vagrant Cascadian <vagrant@debian.org>. * tests/build-utils.scm ("wrap-script, simple case"): Pass SCRIPT-CONTENTS to 'display' rather than 'format'. * gnu/services/base.scm (file-system->shepherd-service-name) [valid-characters, mount-point]: New variables.
