DO NOT REPLY [Bug 49594] New: the "apply" task fails when attribute
parallel=yes and redirector sub-element present
https://issues.apache.org/bugzilla/show_bug.cgi?id=49594
Summary: the "apply" task fails when attribute parallel=yes and
redirector sub-element present
Product: Ant
Version: unspecified
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: critical
Priority: P2
Component: Core
AssignedTo: notifications@ant.apache.org
ReportedBy: vlad.balan@gmail.com
Hello,
ant 1.8.1.
A) i'm getting
java.lang.NullPointerException for the apply task when the attribute
parallel="yes" and a "redirector" sub-element is present.
With parallel=no and redirector present it works fine.
B) what is the exepcted behaviour of a nested outputmapper in the redirector
sub-element ( i.e. a per file output for the command) when parallel=yes (i.e.
the command would be executed one time with the concatenated list of files at
the end of the command)
The doc does not specifies this.
This is why i'm using a "constant" redirector by the means of the "input"
attribute of the redirector element, rather than nesting any "outputmapper".
This is my file with "cmd_files" target:
<?xml version="1.0" encoding="UTF-8"?>
<project>
<patternset id="slash">
<include name="test/" />
</patternset>
<fileset id="filmeFiles" dir="d:/kits">
<patternset refid="slash" />
</fileset>
<target name="echo">
<echo>Content of filmeFiles: ${toString:filmeFiles}</echo>
</target>
<target name="cmd_files" depends="echo">
<apply dir="d:/kits" dest="d:/kits" executable="cmd" parallel="yes"
addsourcefile="yes">
<arg value="/c">
</arg>
<arg value="echo">
</arg>
<targetfile />
<fileset refid="filmeFiles">
</fileset>
<globmapper from="*.txt" to="*_alfa.txt" handledirsep="yes" />
<redirector output="d:\kits\test\output\all_out.txt" append="yes"
/>
</apply>
</target>
</project>

when using parallel mode the redirector is instantiated once per "batch" of
files
that get processed and null is passed in as a source file.

It is a bug and I've fixed it locally - just running the full test suite right
now.
Passing in null as source file is not a bug, that was my answer to your
question B.
You can work around the bug by setting maxparallel to a value > 0.

So A) is a bug but for B) i still don't understand how your replies relate to
B).
The question B) is about the extepcted behaviour of a nested outputmapper in
redirector when parallel=true. What would happen. Pls.put it another way for me
to understand :)
(by the way pls. what is the link to the freshly added doc)

(In reply to comment #5)

it depends on the mapper, just like it does for exec in general. The manual
page for exec says
| Any file mapping is done using a null sourcefile; therefore not
| all Mapper types will return results. When no results are
| returned, redirection specifications will fall back to the task
| level attributes.
and the same is true for apply when parallel is true.
> (by the way pls. what is the link to the freshly added doc)
follow the subversion revision link and you can see the changes.
I haven't updated the online manual, the full page would
be
