2015-03-25t: fix some trivial cases of ignored exit codes in loopsJeff King
These are all cases where we do a setup step of the form: for i in $foo; do set_up $i || break done && more_setup would not notice a failure in set_up (because break always returns a 0 exit code). These are just setup steps that we do not expect to fail, but it does not hurt to be defensive. Most can be fixed by converting the "break" to a "return 1" (since we eval our tests inside a function for just this purpose). A few of the loops are inside subshells, so we can use just "exit 1" to break out of the subshell. And a few can actually be made shorter by just unrolling the loop.

2008-03-13add test_cmp function for test scriptsJeff King
Many scripts compare actual and expected output using "diff -u". This is nicer than "cmp" because the output shows how the two differ. However, not all versions of diff understand -u, leading to unnecessary test failure. This adds a test_cmp function to the test scripts and switches all "diff -u" invocations to use it. The function uses the contents of "$GIT_TEST_CMP" to compare its arguments; the default is "diff -u". On systems with a less-capable diff, you can do: GIT_TEST_CMP=cmp make test Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2007-12-20t4024: fix test script to use simpler sed patternJunio C Hamano
The earlier test stripped away expected number of 'z' but the output would have been very hard to read once somebody broke the common tail optimization. Instead, count the number of 'z' and show it, to help diagnosing the problem better in the future. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2007-12-16Re-re-re-fix common tail optimizationJunio C Hamano
We need to be extra careful recovering the removed common section, so that we do not break context nor the changed incomplete line (i.e. the last line that does not end with LF). Signed-off-by: Junio C Hamano <gitster@pobox.com>
