--- Comment #1 from Eugène Adell <[email protected]> --- Created attachment 36481 --> https://bz.apache.org/bugzilla/attachment.cgi?id=36481&action=edit patch This patch introduces a new attribute wakeUpTransferInterval indicating a time in seconds, to be used with listings that take too much time and trigger a Timeout. When not set, or if the value is <= 0, the old behavior is kept. As there is no way to know in advance if there is such Timeout on the server, and which value is set, we only can discover the timeout value with a first test without this attribute or assume the timeout is likely to be at 60s minimum (probably the common practice among administrators). The command used to trigger a data connection is a LIST on the current file being parsed by the listing. Tested succesfully with this target : <target name="listingWithSymlinks"> <ftp action="list" listing="listingWithSymlinks.txt" server="ftp.ietf.org" port="21" wakeUpTransferInterval="53" remotedir="/rfc/bcp" userid="anonymous" password="anonymous" > <fileset dir="." defaultexcludes="no" includes="*" /> </ftp> </target> output : Buildfile: /home/eadell/tests/ftpant/rfc.xml Adding reference: ant.PropertyHelper Detected Java version: 1.8 in: /usr/local/java/jdk1.8.0_121/jre Detected OS: Linux Adding reference: ant.ComponentHelper Setting ro project property: ant.file -> /home/eadell/tests/ftpant/rfc.xml Setting ro project property: ant.file.type -> file Setting ro project property: ant.project.invoked-targets -> listingWithSymlinks Adding reference: ant.projectHelper Adding reference: ant.parsing.context Adding reference: ant.targets parsing buildfile /home/eadell/tests/ftpant/rfc.xml with URI = file:/home/eadell/tests/ftpant/rfc.xml Setting ro project property: ant.project.name -> FTP test Adding reference: FTP test Setting ro project property: ant.project.default-target -> listing Setting ro project property: ant.file.FTP test -> /home/eadell/tests/ftpant/rfc.xml Setting ro project property: ant.file.type.FTP test -> file Project base dir set to: /home/eadell/tests/ftpant +Target: +Target: feat +Target: listingWithSymlinks +Target: listingWithoutSymlinks +Target: download Adding reference: ant.LocalProperties parsing buildfile jar:file:/home/eadell/base_ant/apache-ant-1.10.5.compiled/dist/lib/ant.jar!/org/apache/tools/ant/antlib.xml with URI = ja r:file:/home/eadell/base_ant/apache-ant-1.10.5.compiled/dist/lib/ant.jar!/org/apache/tools/ant/antlib.xml from a zip file Setting project property: lib -> /home/eadell/tests/ftpant/lib Adding reference: lib Setting ro project property: ant.project.invoked-targets -> listingWithSymlinks Attempting to create object of type org.apache.tools.ant.helper.DefaultExecutor Adding reference: ant.executor Build sequence for target(s) `listingWithSymlinks' is [listingWithSymlinks] Complete build sequence is [listingWithSymlinks, download, listingWithoutSymlinks, feat, ] listingWithSymlinks: [ftp] Opening FTP connection to ftp.ietf.org [ftp] connected [ftp] logging in to FTP server [ftp] login succeeded [ftp] changing the remote directory to /rfc/bcp [ftp] listing files fileset: Setup scanner in dir /home/eadell/tests/ftpant with patternSet{ includes: [*] excludes: [] } wakeUpTransferInterval is reached, trigger a data connection wakeUpTransferInterval is reached, trigger a data connection [ftp] 221 files listed [ftp] disconnecting BUILD SUCCESSFUL Total time: 5 minutes 4 seconds real 5m5.130s user 0m5.852s sys 0m1.016s This patch doesn't prevent other timeouts (such as 421 Session Timeout) that come much later with some servers, that should be adressed in another way. -- You are receiving this mail because: You are the assignee for the bug.
