svn - Dismal svnant performance -


i facing problem svnant. <svnmodified /> takes on 3 minutes complete on working copy (svn metadata version 1.7: using latest svnant head). if try check modifications using tortoisesvn 1.7.12 takes under 3 seconds. if svn status command prompt takes under 3 seconds.

my test build file looks this:

<project name="tools" default="default" basedir=".">    <path id="paths.classpath">     <fileset dir="." casesensitive="false">       <include name="svnant/**/*.jar" />     </fileset>   </path>    <typedef resource="org/tigris/subversion/svnant/svnantlib.xml" classpathref="paths.classpath" />    <fileset id="filesets.svn.modified" dir="c:/workspace/projects">     <svnmodified />   </fileset>    <target name="default">     <pathconvert pathsep="&#xa;" property="target.output" refid="filesets.svn.modified" />     <echo>${target.output}</echo>   </target>  </project>

am doing wrong? tried upgrading svnkit latest version made no difference. including many or few jars? other details: ant 1.9.0, windows 7 x64, java 1.7.0_21 x64

my libs:

+---lib     antlr-runtime-3.4.jar     jna-3.4.0.jar     license-antlr.txt     license-javahl.txt     license-jna.txt     license-sequence.txt     license-sqljet.txt     license-trilead.txt     sequence-library-1.0.2.jar     sqljet-1.1.7.jar     svn-javahl.jar     svnant.jar     svnclientadapter.jar     svnkit-1.7.9.jar     svnkit-cli-1.7.9.jar     svnkit-javahl16-1.7.9.jar     trilead-ssh2-1.0.0-build216.jar

i don't know sure, guess when using svnmodified, svn being queried each file under c:/workspace/projects. when using svn status command line or tortoisesvn, happens within svn software. in first case there lot of little queries 1 file, in second case there 1 query whole file tree.

to improve performance, way can think of is:

  1. calling svn status (via exec or svnant tasks) , output

  2. filter output regexp keep interesting lines modified files

  3. make list of file names , use resourcelist build resource collection flat list of names

some links might interested in implement it:
