From a7c58f280a57ce64e058111b0adbcd6ea846cbdc Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Mon, 8 Aug 2011 03:17:09 +0200 Subject: [PATCH] test: cope better with use of return for errors In olden times, tests would quietly exit the script when they failed at an inconvenient moment, which was a little disconcerting. Therefore v0.99.5~24^2~4 (Trapping exit in tests, using return for errors, 2005-08-10) switched to an idiom of using "return" instead, wrapping evaluation of test code in a function to make that safe: test_run_ () { eval >&3 2>&4 "$1" eval_ret="$?" return 0 } Years later, the implementation of test_when_finished (v1.7.1.1~95, 2010-05-02) and v1.7.2-rc2~1^2~13 (test-lib: output a newline before "ok" under a TAP harness, 2010-06-24) took advantage of test_run_ as a place to put code shared by all test assertion functions, without paying attention to the function's former purpose: test_run_ () { ... eval >&3 2>&4 "$1" eval_ret=$? if should run cleanup then eval >&3 2>&4 "$test_cleanup" fi if TAP format requires a newline here then echo fi return 0 } That means cleanup commands and the newline to put TAP output at column 0 are skipped when tests use "return" to fail early. Fix it by introducing a test_eval_ function to catch the "return", with a comment explaining the new function's purpose for the next person who might touch this code.
