From 6e2f5d0254de75dfe59d27b3c4b45007c109e0bb Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Fri, 20 Apr 2018 09:36:32 +0200 Subject: [PATCH] download/git: fix transform regexp for older tar versions Older versions of tar (e.g. 1.27.1) incorrectly interpret the escaping of the regexp separator, and generate broken tarballs. For example, given the following transform expression: --transform="s/^\.\//squashfs-e38956b92f738518c29734399629e7cdb33072d3\//" the resulting paths in the generated tarball would be: squashfs-e38956b92f738518c29734399629e7cdb33072d3\/ i.e. a directory which last character is indeed a '\'. We fix that by using a separator which is very unlikely to occur in a filename. Fixes: http://autobuild.buildroot.org/results/742/7427f34e5c9f6d043b0fe6ad2c66cc0f31d2b24f/ and probably a slew of others as well... Take this opportunity to fix indentation on the following line (leading spaces, not TABs). Signed-off-by: "Yann E.
