Protect TTY against an expected memory corruption from testcase
tst-malloc-backtrace, which is expected to SIGABRT after a forced memory
corruption.
|
|
While trying to get nptl/tst-initializers1.c to include the test skeleton, I
came across a couple of speed bumps. Firstly: after making the appropriate
changes to the test, running `make check' led to this error:
> In file included from ../malloc/malloc.h:24:0,
..
> from tst-initializers1.c:60:
> ../include/stdio.h:111:1: error: unknown type name `wint_t'
> extern wint_t __getwc_unlocked (FILE *__fp);
So, `wint_t' is used before being defined. Question: Why did test-skeleton.c
not cause this error in any of the other tests that include it?
Anyway, I noticed include/stdio.h includes stddef.h, which in turn defines
`wint_t', but only if `__need_wint_t' is defined. So I put in a
`#define __need_wint_t' before the include to get rid of the error. Is that
the correct fix?
A subsequent `make && make check' led to this second error:
> from tst-initializers1-c89.c:1:
> ../test-skeleton.c: In function `main':
> ../test-skeleton.c:356:11: error: `for' loop initial declarations are only
> allowed in C99 mode
> for (struct temp_name_list *n = temp_name_list;
Although there seem to be several other C89 no-noes in test-skeleton.c, I
needed only to fix this specific one for gcc-4.8.3 to stop complaining.

add_temp_file now makes a copy which is freed by delete_temp_files.
Callers to create_temp_file can now free the returned file name to
avoid the memory leak. These changes do not affect the leak behavior
of existing code.
Also address a NULL pointer derefence in tzset after a memoru allocation
failure, found during testing.

Modifies the test examination in test-skeleton.c so that a test can be
successful if it is interrupted or it returns uninterrupted with the
expected status. For this both EXPECTED_SIGNAL and EXPECTED_STATUS
have to be set, as is done in tst-strcoll-overflow.c.

This makes sure any subprocesses created by the program being tested get
killed as well if their parent times out. Otherwise if they are really
stuck, they may remain there running forever after the test case and
then the whole test suite has completed, until killed by hand.
* test-skeleton.c (signal_handler): Kill the whole process group
before killing the child individually.
(main): Report any failure on `setpgid'.

At the moment the test skeleton uses a mixture of stdout and
stderr for error message output. Using stdout for all test output
keeps all output correctly ordered and properly redirected to the
output file. The suggestion to use stdout is also made on the wiki:
https://sourceware.org/glibc/wiki/Testing/Testsuite#Writing_a_test_case
ChangeLog:
2014-06-23 Will Newton <will.newton@linaro.org>
* test-skeleton.c (signal_handler): Use printf and %m
rather than perror. Use printf rather than fprintf to
stderr. Use puts rather than fputs to stderr.
(main): Likewise.
|

We have multiple tests that copy & paste the same logic for disabling the
fortification output. Let's unify this in the test-skeleton instead.
