* utils: Allow text substitution even in the presence of NUL characters.Mark H Weaver2021-01-08
| | | | | | | | | | | | | | | | | | | | | | Fixes <https://issues.guix.gnu.org/30116>. 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.

* utils: 'wrap-script' doesn't pass a non-literal string to 'format'.Ludovic Courtès2020-11-17
| | | | | | | | Reported by Vagrant Cascadian <vagrant@debian.org> in <https://bugs.gnu.org/44626>. * guix/build/utils.scm (wrap-script): Use 'display' instead of passing a non-literal string to 'format'.
* packages, scripts, utils: Enable multi-threaded xz compression.Maxim Cournoyer2020-10-08
| | | | | | | | | | | | | | | | | xz compression is slow; using the multi-thread mode of xz can make it more than 6 times faster, for example when compressing the large linux-libre source. * guix/build/utils.scm (%xz-parallel-args): New procedure. * guix/packages.scm (patch-and-repack): Specify the required above xz arguments by setting the XZ_DEFAULTS environment variable. * guix/scripts/pack.scm (%compressors, bootstrap-xz): Modify the commands Gexps so they do not need to be quoted. This allows lazily evaluating the arguments on the builder's side. Specify the required xz arguments. (self-contained-tarball): Do not quote the compressor command value. (docker-image): Likewise. * guix/utils.scm (decompressed-port, compressed-port) (compressed-output-port): Specify the required above xz arguments.
* utils: Do not raise exceptions in delete-file-recursively.Maxim Cournoyer2020-10-08
| | | | | | | | | | | | | This makes it so that delete-file-recursively honors its docstring, which says it should "report but ignore errors". Fixes <https://issues.guix.gnu.org/43366>. * guix/build/utils.scm (warn-on-error): New syntax. (delete-file-recursively): Use it to catch exceptions and print warning messages.
