An unclosed here-doc in a test is a problem, because it silently gobbles
up any remaining commands. Since 99a64e4b73
(tests: lint for run-away
here-doc, 2017-03-22) we detect this by piggy-backing on the internal
chainlint checker in test-lib.sh.
However, it would be nice to detect it in chainlint.pl, for a few
reasons:
- the output from chainlint.pl is much nicer; it can show the exact
spot of the error, rather than a vague "somewhere in this test you
broke the &&-chain or had a bad here-doc" message.
- the implementation in test-lib.sh runs for each test snippet. And
since it requires a subshell, the extra cost is small but not zero.
If chainlint.pl can reliably find the problem, we can optimize the
test-lib.sh code.
The chainlint.pl code never intended to find here-doc problems. But
since it has to parse them anyway (to avoid reporting problems inside
here-docs), most of what we need is already there. We can detect the
problem when we fail to find the missing end-tag in swallow_heredocs().
The extra change in scan_heredoc_tag() stores the location of the start
of the here-doc, which lets us mark it as the source of the error in the
output (see the new tests for examples).
