#include <sys/types.h>
|
skip ioctl-using tests when not supported
Summary:
[NB: this is a prerequisite for the /tmp-abuse-fixing patch]
This avoids spurious test failure on Linux systems
like Fedora for which /tmp is a tmpfs file system.
On a devtmpfs file
system, ioctl(fd, FS_IOC_GETVERSION, &version) returns -1 with
errno == ENOTTTY, indicating that that ioctl is not supported
on such a file system. Do not let this cause test failures, e.g.,
where env_test would assert that file->GetUniqueId(...) > 0.
Before this change, ./env_test would fail these three tests
on a fedora rawhide system:
[ FAILED ] 3 tests, listed below:
[ FAILED ] EnvPosixTest.RandomAccessUniqueID
[ FAILED ] EnvPosixTest.RandomAccessUniqueIDConcurrent
[ FAILED ] EnvPosixTest.RandomAccessUniqueIDDeletes
3 FAILED TESTS
The fix:
When support for that ioctl is lacking, skip each affected test.
Could be improved by noting which sub-tests are being skipped.
Test Plan:
run these on F21 and note that they now pass.

skip ioctl-using tests when not supported
Summary:
[NB: this is a prerequisite for the /tmp-abuse-fixing patch]
This avoids spurious test failure on Linux systems
like Fedora for which /tmp is a tmpfs file system.
On a devtmpfs file
system, ioctl(fd, FS_IOC_GETVERSION, &version) returns -1 with
errno == ENOTTTY, indicating that that ioctl is not supported
on such a file system. Do not let this cause test failures, e.g.,
where env_test would assert that file->GetUniqueId(...) > 0.
Before this change, ./env_test would fail these three tests
on a fedora rawhide system:
[ FAILED ] 3 tests, listed below:
[ FAILED ] EnvPosixTest.RandomAccessUniqueID
[ FAILED ] EnvPosixTest.RandomAccessUniqueIDConcurrent
[ FAILED ] EnvPosixTest.RandomAccessUniqueIDDeletes
3 FAILED TESTS
The fix:
When support for that ioctl is lacking, skip each affected test.
Could be improved by noting which sub-tests are being skipped.
Test Plan:
run these on F21 and note that they now pass.

skip ioctl-using tests when not supported
Summary:
[NB: this is a prerequisite for the /tmp-abuse-fixing patch]
This avoids spurious test failure on Linux systems
like Fedora for which /tmp is a tmpfs file system.
On a devtmpfs file
system, ioctl(fd, FS_IOC_GETVERSION, &version) returns -1 with
errno == ENOTTTY, indicating that that ioctl is not supported
on such a file system. Do not let this cause test failures, e.g.,
where env_test would assert that file->GetUniqueId(...) > 0.
Before this change, ./env_test would fail these three tests
on a fedora rawhide system:
[ FAILED ] 3 tests, listed below:
[ FAILED ] EnvPosixTest.RandomAccessUniqueID
[ FAILED ] EnvPosixTest.RandomAccessUniqueIDConcurrent
[ FAILED ] EnvPosixTest.RandomAccessUniqueIDDeletes
3 FAILED TESTS
The fix:
When support for that ioctl is lacking, skip each affected test.
Could be improved by noting which sub-tests are being skipped.
Test Plan:
run these on F21 and note that they now pass.
