From 4a7af4edbb800ff8ed0cd131423f45c2c76e1200 Mon Sep 17 00:00:00 2001 From: Patrick Steinhardt Date: Thu, 3 Apr 2025 07:06:04 +0200 Subject: t: refactor tests depending on Perl for textconv scripts We have a couple of tests that depend on Perl for textconv scripts. Refactor these tests to instead be implemented via shell utilities so that we can drop a couple of PERL_TEST_HELPERS prerequisites. Note that the conversion in t4030 is not a one-to-one equivalent to the previous textconv script. Before this change we used to essentially do a hexdump via Perl. The obvious conversion here would be to use `test-tool hexdump` like we do for the other tests. But this would lead to a ripple effect where we would have to adapt a bunch of other tests with a bunch of seemingly unrelated changes, which would be somewhat awkward. Instead, we're going with the minimum viable change: the test files we write contain "\001" and "\000", and the test's expectation is that those get translated into proper ASCII characters. So instead of doing a full hexdump, we simply use tr(1) to translate these specific bytes.
