[RFC/PATCH v2] t3300-*.sh: Fix a TAP parse error
From: Ramsay Jones <hidden>
Date: 2016-06-15 22:54:19
At present, running the t3300-*.sh test on cygwin looks like:
$ cd t
$ ./t3300-funny-names.sh
ok 1 - setup
# passed all 1 test(s)
1..1 # SKIP Your filesystem does not allow tabs in filenames
$
Unfortunately, this is not valid TAP output, which prove notes
as follows:
$ prove --exec sh t3300-funny-names.sh
t3300-funny-names.sh .. All 1 subtests passed
Test Summary Report
-------------------
t3300-funny-names.sh (Wstat: 0 Tests: 1 Failed: 0)
Parse errors: No plan found in TAP output
Files=1, Tests=1, 2 wallclock secs ( 0.05 usr 0.00 sys + \
0.90 cusr 0.49 csys = 1.43 CPU)
Result: FAIL
$
This is due to the 'trailing_plan' having a 'skip_directive'
attached to it. This is not allowed by the TAP grammar, which
only allows a 'leading_plan' to be followed by an optional
'skip_directive'. (see perldoc TAP::Parser::Grammar).
A trailing_plan is one that appears in the TAP output after one or
more test status lines (that start 'not '? 'ok ' ...), whereas a
leading_plan must appear before all test status lines (if any).
In practice, this means that the test script cannot contain a use
of the 'skip all' facility:
skip_all='Some reason to skip *all* tests in this file'
test_done
after having already executed one or more tests with (for example)
'test_expect_success'. Unfortunately, this is exactly what this
test script is doing. The first 'setup' test is actually used to
determine if the test prerequisite is satisfied by the filesystem
(ie does it allow tabs in filenames?).
In order to fix the parse errors, place the code to determine the
test prerequisite at the top level of the script, prior to the
first test, rather than as a parameter to test_expect_success.
This allows us to correctly use 'skip_all', thus:
$ ./t3300-funny-names.sh
# passed all 0 test(s)
1..0 # SKIP Your filesystem does not allow tabs in filenames
$
$ prove --exec sh t3300-funny-names.sh
t3300-funny-names.sh .. skipped: Your filesystem does not \
allow tabs in filenames
Files=1, Tests=0, 2 wallclock secs ( 0.02 usr 0.03 sys + \
0.84 cusr 0.41 csys = 1.29 CPU)
Result: NOTESTS

Hi Jonathan,
This version of the patch only moves code to determine the test
prerequisite to the outer level, while leaving the 'setup' aspects
of the first test in place.
I did think about merging the following test ("setup: populate index
and tree") into the first test, but I wanted to keep it simple for now.
What do you think?
ATB,
Ramsay Jones
