DO NOT REPLY [Bug 50507] New: Exec task may mix the stderr and
stdout output while logging it
https://issues.apache.org/bugzilla/show_bug.cgi?id=50507
Summary: Exec task may mix the stderr and stdout output while
logging it
Product: Ant
Version: 1.8.1
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: critical
Priority: P2
Component: Core tasks
AssignedTo: notifications@ant.apache.org
ReportedBy: william.bernardet@gmail.com
It looks like Ant 1.8.1 (also verified with future 1.8.2 from CI
https://hudson.apache.org/hudson/view/A-F/view/Ant/job/Ant_Nightly/187/artifact/)
can mix stderr and stdout stream output while logging it. The following example
can easily help to reproduce the issue:
<?xml version="1.0">
<project>
<target name="demo">
<exec executable="${ant.home}/bin/ant.bat">
<arg value="-f" />
<arg file="${ant.file}" />
<arg value="generate-output" />
</exec>
</target>
<target name="generate-output">
<echo>${ant.version}</echo>
<echo message="some blablablablablablablablablablablabla error message"
level="error" />
<echo message="some blablablablablablablablablablablabla info message"
level="info" />
<echo message="some blablablablablablablablablablablabla error message"
level="error" />
<echo message="some blablablablablablablablablablablabla info message"
level="info" />
<echo message="some blablablablablablablablablablablabla error message"
level="error" />
<echo message="some blablablablablablablablablablablabla info message"
level="info" />
<echo message="some blablablablablablablablablablablabla error message"
level="error" />
<echo message="some blablablablablablablablablablablabla info message"
level="info" />
<echo message="some blablablablablablablablablablablabla error message"
level="error" />
<echo message="some blablablablablablablablablablablabla info message"
level="info" />
</target>
</project>
Executed with Ant 1.8.1, a message on stderr can be printed in the middle of an
another message coming from stdout:
C:\...>ant demo
Buildfile: C:\apps\test\build.xml
demo:
[exec] Buildfile: C:\apps\test\build.xml
[exec]
[exec] generate-output:
[exec] [echo] Apache Ant version 1.8.1 compiled on April 30 2010
[exec] [echo] some blablablablablablablablablablablabla info message
[exec] [echo] some blablablablablablablablablablablabla info message
[exec] [echo] some blablablablablablablablablablablabla in [echo]
some blablablablablablablablablablablabla error message
[exec] [echo] some blablablablablablablablablablablabla error message
[exec] [echo] some blablablablablablablablablablablabla error message
[exec] [echo] some blablablablablablablablablablablabla error message
[exec] [echo] some blablablablablablablablablablablabla error message
[exec] fo message
[exec] [echo] some blablablablablablablablablablablabla info message
[exec] [echo] some blablablablablablablablablablablabla info message
[exec]
[exec] BUILD SUCCESSFUL
[exec] Total time: 0 seconds
BUILD SUCCESSFUL
Total time: 1 second
Same script executed with Ant 1.7.0 will log the output of each stream
correctly (line by line):
C:\apps\test>ant demo
Buildfile: build.xml
demo:
[exec] Buildfile: C:\apps\test\build.xml
[exec]
[exec] generate-output:
[exec] [echo] Apache Ant version 1.7.0 compiled on December 13 2006
[exec] [echo] some blablablablablablablablablablablabla error message
[exec] [echo] some blablablablablablablablablablablabla error message
[exec] [echo] some blablablablablablablablablablablabla error message
[exec] [echo] some blablablablablablablablablablablabla info message
[exec] [echo] some blablablablablablablablablablablabla info message
[exec] [echo] some blablablablablablablablablablablabla info message
[exec] [echo] some blablablablablablablablablablablabla info message
[exec] [echo] some blablablablablablablablablablablabla info message
[exec] [echo] some blablablablablablablablablablablabla error message
[exec] [echo] some blablablablablablablablablablablabla error message

I can reproduce this on Windows. It is not a systematic bug.
It is similar or the same bug like 48746

This test fails in trunk using JDK 5u22 or 6u31 or 7u3 on Ubuntu:
src/etc/testcases/taskdefs/exec/exec.xml:60: output indicates a mixup of out
and err
at org.apache.tools.ant.taskdefs.Exit.execute(Exit.java:164)
...
at
org.apache.tools.ant.taskdefs.ExecTaskTest.testOutAndErr(ExecTaskTest.java:108)
Sometimes it passes, but usually it fails. I made the test better report the
failure, showing the following output:
doit:

Actually the issue is coming from the merging of stdout and stderr by the
OutputStreamFunneler class without having any consideration about line ending.

Committed revision 1297113 to disable the test since it consistently fails for
me on Ubuntu, and according to [1] on the CI builder as well.

Do you think this issue will be addressed in 1.8.2?

William thanks very much for the patch. A release candidate for 1.8.2 is
already built and should be released officially on 12/27. Your patch can make
it into 1.8.3 if it passes the tests and no one sees architectural or
performance problems with it. Do not worry, we can build 1.8.3 relatively fast
after 1.8.2.
