Right now, the makefiles in host/rootfs, vm/sys/net, and img/app have manually-maintained lists of files and symlinks. These duplicate the information in the git repository and can easily get out of sync or cause unnecessary merge conflicts. Fix all of these issues by having the git repository be the source of truth, and using a script to generate the file lists. Developers can regenerate the lists before every commit, or even add a git hook to do that. Signed-off-by: Demi Marie Obenour <demiobenour@gmail.com> --- This actually reduces the amount of code that has to be written by hand. --- Changes in v5: - Use 'print ""' instead of 'print' in awk to print a newline. 'print' with no arguments implicitly prints $0 instead. This caused the generated makefiles to be incorrect. - Use S6_RC_FILES instead of VM_S6_RC_FILES in vm/sys/net/Makefile and img/app/Makefile. This prevented the image from being built. - Do not check for git repository being in a directory with a name ending in a newline. - Use shell redirection instead of awk redirection. - Do not include trailing DONE line in input to awk. - Link to v4: https://lore.kernel.org/r/20250921-genfiles-v4-1-4375bda78707@gmail.com Changes in v4: - Use /bin/sh instead of bash. - Do not assume that negated awk character classes match all bytes. - Do not check the mode of license files. - Use implicit awk variable initialization. - Use 'git rev-parse --show-toplevel' to find the repository root. - Remove wrongly added copyright header. - Improve documentation. - Remove git hooks. - Add missing copyright header. - Avoid non-portable /usr/bin/env -S. - Avoid assuming that awk is GNU awk. - Avoid non-portable awk -E. - Do not check for git bugs. - Fix link in v3 changelog. - Link to v3: https://spectrum-os.org/lists/archives/spectrum-devel/20250920-genfiles-v3-1... Changes in v3: - Only include the file list generator. Move the rest to separate patch series. - Remove the update-file-list make targets from img/app/Makefile and vm/sys/net/Makefile. - Link to v2: https://spectrum-os.org/lists/archives/spectrum-devel/20250910-genfiles-v2-0... Changes in v2: - Drop the last patch (switching to /etc/s6-rc/compiled) as it is controversial and should be reviewed separately. - Add missing copyright notices. - Use a wrapper shell script to make the awk code easier to read. - Improve documentation. - Add helper scripts for use in git hooks and rebasing. - Link to v1: https://spectrum-os.org/lists/archives/spectrum-devel/20250903-genfiles-v1-0... --- Documentation/development/built-in-vms.adoc | 7 ++ host/rootfs/Makefile | 102 +--------------------------- host/rootfs/file-list.mk | 99 +++++++++++++++++++++++++++ img/app/Makefile | 82 ++++------------------ img/app/file-list.mk | 65 ++++++++++++++++++ scripts/genfiles.awk | 77 +++++++++++++++++++++ scripts/genfiles.sh | 24 +++++++ vm/sys/net/Makefile | 52 +++----------- vm/sys/net/file-list.mk | 42 ++++++++++++ 9 files changed, 337 insertions(+), 213 deletions(-) diff --git a/Documentation/development/built-in-vms.adoc b/Documentation/development/built-in-vms.adoc index e90009ee5a3c2c254a7ae11e36121576b819eee7..d044e7509a43df4b015f312dac61be6c74cc7feb 100644 --- a/Documentation/development/built-in-vms.adoc +++ b/Documentation/development/built-in-vms.adoc @@ -3,6 +3,7 @@ :page-nav_order: 3 // SPDX-FileCopyrightText: 2023-2025 Alyssa Ross <hi@alyssa.is> +// SPDX-FileCopyrightText: 2025 Demi Marie Obenour <demiobenour@gmail.com> // SPDX-License-Identifier: GFDL-1.3-no-invariants-or-later OR CC-BY-SA-4.0 Spectrum comes with some built-in application VMs, to demonstrate @@ -44,6 +45,12 @@ NOTE: As a special convenience, it's not necessary to run `make clean` if the only change to the Nix files is modifying the packages installed in the VM. +The list of files used for images is stored in a separate file, +file-list.mk.
