I'd like to ask people to test the latest snapshot as of today. It contains
two patches, one of them with some impact on how timestamps are used.
The first patch is less important, it should just stop floppy access when
sync is called on Win2K boxes.
The second patch is this:
In 1.5.13 and 1.5.14 we introduced touching the CreationTime stamp in
a way, which simulates a POSIX ctime using the CreationTime stamp.
This resulted in some complaints, the most important one that native
Windows applications might misbehave because of strange CreationTimes.
The snapshot now contains a patch which changes the ctime handling as
follows:
- Windows NT supports a fourth timestamp which is inaccessible from the
Win32 API. The NTFS filesystem actually implements it. It behaves
as a ctime in a POSIX-like fashion. Cygwin's st_ctime stat member now
contains this ChangeTime, if it's available.
- Any other file system, which doesn't support the ChangeTime stamp
uses the LastWriteTime stamp as ctime. This comes relatively close
to the way ctime behaves in POSIX.
- The CreationTime stamp is neither read nor changed programatically by
Cygwin now. This should solve the aforementioned problems for native
Win32 applications.
Please download from http://www.cygwin.com/snapshots/ and test.
Thanks,
Corinna
