* bash scripts: use /usr/bin/env for bash shebangsGraham Christensen2020-02-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Not all systems / distros have a `/bin/bash`, and these scripts are more difficult to run at development time. For example, my system is NixOS which doesn't have a /bin/bash. This is not a problem for NixOS building ZFS as a package: the build environment automatically replaces these shebangs with corrected paths. The problem is much more annoying at development time: either the scripts don't run, or I correct them for my local machine and deal with a perpetually dirty work tree. Before committing this patch I confirmed there are existing scripts which use `/usr/bin/env` to locate bash, so I am thinking this is a safe transformation. There are a handful of other shebangs in this repository which don't work on my system. This patch is useful on its own specifically for `commitcheck.sh`, otherwise I can't validate my commits before submission. Here are the remaining shebangs which NixOS systems won't have: 1274 #!/bin/ksh -p 91 #!/bin/ksh 89 #! /bin/ksh -p 2 #!/bin/sed -f 1 #!/usr/bin/perl -w 1 #!/usr/bin/ksh 1 #!/bin/nawk -f plus this which will create an invalid shebang in `tests/zfs-tests/tests/functional/mv_files/mv_files_common.kshlib`: echo "#!/bin/ksh" > $TEST_BASE_DIR/exitsZero.ksh I chose to leave those alone for now, and gauge the interest in this much smaller patch first. The fixes for these are easy enough by simply using `/usr/bin/env ksh`: 91 #!/bin/ksh 1 #!/usr/bin/ksh The fix for the other set is much trickier. Quoting the GNU coreutils manual: Most operating systems (e.g. GNU/Linux, BSDs) treat all text after the first space as a single argument. When using env in a script it is thus not possible to specify multiple arguments. and not all `env`'s support arguments. Mine (GNU Coreutils 8.31) does, though this feature is new since April 2018, GNU Coreutils 8.30: https://git.savannah.gnu.org/cgit/coreutils.git/commit/?id=668306ed86c8c79b0af0db8b9c882654ebb66db2 and worse, requires the -S argument: -S, --split-string=S process and split S into separate arguments; used to pass multiple arguments on shebang lines Example: $ seq 1 2 | $(nix-build '<nixpkgs>' -A coreutils)/bin/env "sort -nr" /nix/[...]-coreutils-8.31/bin/env: ‘sort -nr’: No such file or directory /nix/[...]-coreutils-8.31/bin/env: use -[v]S to pass options in shebang lines $ seq 1 2 | $(nix-build '<nixpkgs>' -A coreutils)/bin/env "-S sort -nr" 2 1 GNU Coreutils says FreeBSD's `env` does, though I wonder if FreeBSD's would be unhappy with the `-S`: https://www.gnu.org/software/coreutils/manual/html_node/env-invocation.html#env-invocation BusyBox v1.30.1 does not, and does not have a `-S`-like option: $ seq 1 2 | $(nix-build '<nixpkgs>' -A busybox)/bin/env "sort -nr" env: can't execute 'sort -nr': No such file or directory Toybox 0.8.1 also does not, and also does not have a `-S` option: $ seq 1 2 | $(nix-build '<nixpkgs>' -A toybox)/bin/env "sort -nr" env: exec sort -nr: No such file or directory --- At any rate, if this patch merges and the remaining ~1,500 are updated, the much larger patch should probably include a checkstyle-like test asserting all new shebangs use `/usr/bin/env`. I also don't mind dealing with NixOS weirdness if the project would prefer that.

* Restore :: in Makefile.amRyan Moeller2019-08-261-0/+2
| | | | | | | | | | | | The double-colon looked like a typo, but it's actually an obscure feature. Rules with :: may appear multiple times and are run independently of one another in the order they appear. The use of :: for distclean-local was conventional, not accidental. Add comments to indicate the intentional use of double-colon rules. Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Ryan Moeller <[email protected]> Closes #9210

| | | | | | | | | | | while these are source by dracut (which is a bash script) the practical difference is small, but it is more correct: /bin/sh is not bash on all systems (e.g. Debian and its derivatives use /bin/dash as /bin/sh by default).

* fix booting via dracut generated initramfsMatthew Thode2016-04-252-0/+154
Dracut and Systemd updated how they integrate with each other, because of this our current integrations stopped working (around the time 4.1.13 came out). This patch addresses that issue and gets us booting again. Thanks to @Rudd-O for doing the work to get dracut working again and letting me submit this on his behalf.
