http://issues.apache.org/bugzilla/show_bug.cgi?id=42544 Summary: cannot have multiple input tasks with command line redirection Product: Ant Version: 1.7.0 Platform: Other OS/Version: other Status: NEW Severity: normal Priority: P2 Component: Core tasks AssignedTo: dev@ant.apache.org ReportedBy: [EMAIL PROTECTED] In 1.6.2 it used to be possible to invoke an ant script from an external java program (or shell command) where input values were passed through command line redirection with each value being terminated by a new line. In 1.7.0 it appears this functionality has been broken since the DefaultInputHandler has been modified to use a BufferedReader inside the handleInput method. The problem with this is that in the first input task, the bufferedreader will read up to the buffer size (8k), however the DefaultInputHandler will only consume the first line of this. When the second input task comes along it will not find anything (i guess maybe if you had very large input you might find something). We have a similar problem elsewhere in our code and we handled it by creating a single static BufferedReader around System.in that was shared. This means that line 1 can be read by one bit of code, line by the next and so on because they are using a single BufferedReader. In 1.6.2 the old code was using DataInputStream.readLine which is deprecated and probably why the new code uses BufferedReader. In order to solve my particular problem, I have written an extension of BufferedReader which uses a single shared BufferReader around System.in. However this is not a general purpose problem to the solution i think as the InputHandler should handle the contract of working with the passed in stream. One possible solution might be to implement a custom LineReader that does not rely in BufferedReader. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
