Like I wrote, I think it’s good to have this check even if there were no hard limits, mostly as a style guideline. > From c0738574a3571977855d655c157ab0ea0f9be6ef Mon Sep 17 00:00:00 2001 > From: Vagrant Cascadian <vagrant@debian.org> > Date: Fri, 26 Nov 2021 12:13:45 -0800 > Subject: [PATCH] lint: Adjust patch file length check. > > With the switch to "ustar" format in commit > bdf5c16ac052af2ca9d5c3acc4acbc08fd9fdbea, the maximum file length has > increased. > > * guix/lint.scm (check-patch-file-names): Adjust margin used to check for > patch file lengths.

That should bright all the patches into compliance with lint as far as file length goes, and should work with the ustar format for the "make dist" produced tarballs. Don't get too crazy with the extra ~50 characters! live well, vagrant
From c0738574a3571977855d655c157ab0ea0f9be6ef Mon Sep 17 00:00:00 2001 From: Vagrant Cascadian <vagrant@debian.org> Date: Fri, 26 Nov 2021 12:13:45 -0800 Subject: [PATCH] lint: Adjust patch file length check. With the switch to "ustar" format in commit bdf5c16ac052af2ca9d5c3acc4acbc08fd9fdbea, the maximum file length has increased. * guix/lint.scm (check-patch-file-names): Adjust margin used to check for patch file lengths. Increase allowable patch file length appropriate to new tar format. Extend warning to explain that long files may break 'make dist'. * tests/lint.scm: Update tests accordingly. --- guix/lint.scm | 9 ++++++--- tests/lint.scm | 8 ++++---- 2 files changed, 10 insertions(+), 7 deletions(-) diff --git a/guix/lint.scm b/guix/lint.scm index ac2e7b3841..4a5573e86e 100644 --- a/guix/lint.scm +++ b/guix/lint.scm @@ -957,8 +957,11 @@ patch could not be found." ;; Check whether we're reaching tar's maximum file name length.
