http://nagoya.apache.org/bugzilla/show_bug.cgi?id=16270 copy date bug when copying from ntfs to samba mounted drive Summary: copy date bug when copying from ntfs to samba mounted drive Product: Ant Version: 1.5.1 Platform: PC OS/Version: Windows NT/2K Status: NEW Severity: Normal Priority: Other Component: Core tasks AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] The copy task has a java vm caused bug when it interacts with a samba mounted file system from linux/unix machine while the ant task is running on a windows machine. I had 3 different files that I created on the ntfs drive (all done from a W2K machine). I then copied the three files to the samba share mounted drive. Here are the last 5 digits of the time stamps that the java vm reports. I don't understand its behavior... As some round down, and some up. File a File b File c Local NTFS 35062 87359 18093 Mounted via samba 36000 88000 18000 As you can imagnine, this leads to a lot of unnecessary file copying by the copy task, as file c would have been recopied, even though it doesn't need to be. To fix this, I added a dateSlop feature to the copy so that it would only copy files that are more than 1 second apart from each other in their time stamps when dateSlop is set to true. I don't know ant well enough, however to know all the implications of this change. This bug is annoying when it is used to copy large amounts of files. It also turns into a showstopper for the new synchronize task that has been posted as a requested enhancement, when it is used to synchronize a ntfs drive with a samba mounted drive... you end up copying upwards of 1/2 of the files in your set (even if none of them have actually changed) -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
