http://nagoya.apache.org/bugzilla/show_bug.cgi?id=22148 make the byte-for-byte compairson of files optional on the <different> selector Summary: make the byte-for-byte compairson of files optional on the <different> selector Product: Ant Version: 1.6Alpha (nightly) Platform: All OS/Version: All Status: NEW Severity: Enhancement Priority: Other Component: Core tasks AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] The new <different> selector works like this, according to the documentation: 1. If there is no 'other' file, it's different. 2. Files with different lengths are different. 3. If ignoreFileTimes is turned off, then differing file timestamps will cause files to be regarded as different. 4. Finally a byte-for-byte check is run against the two files A byte for byte compairson is far to slow to use for copying large amounts of files across a network connection. I was going to propose that we add a new step after 3 that would do an MD5 compairson, and then make step 4 optional but then realized that you have to read the whole file to compute an MD5. So that wouldn't really help. So I would like to ask that step 4 be made optional, so that when we can avoid the time expense of comparing the files if necessary. Also, could this be done before 1.6 goes final? --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
