Bug #89073 Space missing in OOS error message

Description:
2017-12-28T13:00:11.773037Z 9 [ERROR] InnoDB: Write to file ./ibdata1failed at offset 23068672, 1048576 bytes should have been written, only 417792 were written. Operating system error number 28. Check that your OS and file system support files of this size. Check also that the disk is not full or a disk quota exceeded.

Note: "Write to file ./ibdata1failed" - it is missing a space before failed

How to repeat:
Run out of space and run into said error message. 

This can also be verified based on code review I assume.

Thanks for the report.  The code in 5.7 :

static MY_ATTRIBUTE((warn_unused_result))
dberr_t
os_file_write_page(
	IORequest&	type,
	const char*	name,
	os_file_t	file,
	const byte*	buf,
	os_offset_t	offset,
	ulint		n)
{
	dberr_t		err;
	ut_ad(type.validate());
	ut_ad(n > 0);

	ssize_t n_bytes = os_file_pwrite(type, file, buf, n, offset, &err);

	if ((ulint) n_bytes != n && !os_has_said_disk_full) {

		ib::error()
			<< "Write to file " << name << "failed at offset "
			<< offset << ", " << n
			<< " bytes should have been written,"
			" only " << n_bytes << " were written."
			" Operating system error number " << errno << "."
			" Check that your OS and file system"
			" support files of this size."
			" Check also that the disk is not full"
			" or a disk quota exceeded.";

While in 8.0 we see the space....

static MY_ATTRIBUTE((warn_unused_result))
dberr_t
os_file_write_page(
	IORequest&	type,
	const char*	name,
	os_file_t	file,
	const byte*	buf,
	os_offset_t	offset,
	ulint		n)
{
	dberr_t		err;

	ut_ad(type.validate());
	ut_ad(n > 0);

	ssize_t n_bytes = os_file_pwrite(type, file, buf, n, offset, &err);

	if ((ulint) n_bytes != n && !os_has_said_disk_full) {

		ib::error()
			<< "Write to file " << name << " failed at offset "
			<< offset << ", " << n
			<< " bytes should have been written,"
			" only " << n_bytes << " were written."
			" Operating system error number " << errno << "."
			" Check that your OS and file system"
			" support files of this size."
			" Check also that the disk is not full"
			" or a disk quota exceeded.";

It was really fixed in 8.0 by:
