Hi, A workaround for people migrating from ant 1.5 to ant 1.6 and wanting to keep antcall is to set inheritrefs to false.
I have found the diffs for the fix which I checked in on July 22nd. http://marc.theaimsgroup.com/?l=ant-dev&m=105887513827839&w=2 Is this improvable for performance ? Is this really such a critical problem to deliver ant 1.6 ? Cheers, Antoine -----Ursprungliche Nachricht----- Von: Peter Reilly [mailto:[EMAIL PROTECTED] Gesendet: Mittwoch, 10.

I was bashing my head against a wall looking into this. :-( For my simple scripts, ant 1.6 (using crimson as against xerces) was faster than ant 1.5. 8-) But now this script: <project default="y"> <fileset id="set" dir="."> <include name="**/*.xml"/> </fileset> <target name="y"> </target> </project> Takes 1.5 seconds on ant1.6 against 1.2 on ant 1.5. and without the id: <project default="y"> <fileset dir="."> <include name="**/*.xml"/> </fileset> <target name="y"> </target> </project> Takes 0.55 on ant1.6 against 1.1 on ant 1.5. Using antcall makes this effect much worse: <project default="calls"> <fileset id="set" dir="."> <include name="**/*.xml"/> </fileset> <target name="y"> </target> <target name="calls"> <antcall target="y"/> <antcall target="y"/> <antcall target="y"/> <antcall target="y"/> <antcall target="y"/> <antcall target="y"/> <antcall target="y"/><project default="calls"> <fileset id="set" dir="."> <include name="**/*.xml"/> </fileset> <target name="y"> </target> <target name="calls"> <antcall target="y"/> <antcall target="y"/> <antcall target="y"/> <antcall target="y"/> <antcall target="y"/> <antcall target="y"/> <antcall target="y"/> <antcall target="y"/> <antcall target="y"/> <antcall target="y"/> </target> </project> <antcall target="y"/> <antcall target="y"/> <antcall target="y"/> </target> </project> Takes 4.5 seconds on ant1.6 against 1.4 seconds on ant1.5.
