---------------------------------------------------------
Key: JRUBY-5904
URL: https://jira.codehaus.org/browse/JRUBY-5904
Project: JRuby
Issue Type: Bug
Components: JRuby-extras
Affects Versions: JRuby 1.6.2
Environment: windows xp,vista, ant1.8.1
Reporter: Andyma
We are using JRuby with ant, it works very well with version 1.4.1, when
upgrade to 1.6.2, we have many errors related to "Bad file descriptor", the
stacktrace is as follow:
[createupdatevcproj] Bad file descriptor - Bad file descriptor
[createupdatevcproj] org/jruby/RubyIO.java:1330:in `write'
[createupdatevcproj] <script>:31:in `(root)'
[createupdatevcproj] org/jruby/RubyIO.java:1122:in `open'
[createupdatevcproj] <script>:30:in `(root)' (<script> l.35)
part of ant file:
....
<for param="projectfile" parallel="true" threadCount="10">
<filelist refid="qmake.project.files" />
<sequential>
<createupdatevcproj projectfile="@{projectfile}" />
</sequential>
</for>
...
the definition of "createupdatevcproj":
<scriptdef name="createupdatevcproj" language="ruby">
<attribute name="projectfile" />
<![CDATA[
begin
antdir = $project.getProperty("global.antdir")
devtdir = $project.getProperty("global.devtools")
qtdir = $project.getProperty("global.qtdir")
rubydir = $project.getProperty("global.rubydir")
mkspec = $project.getProperty("build.mkspec")
ttbuild = $project.getProperty("global.basedir")+"/Build"
projectfile = $attributes.get("projectfile")
require antdir + "/antlogging.rb"
require 'pathname'
pro_dir = File.dirname(projectfile)
pro_file = File.basename(projectfile)
commands = "@echo off \n"
commands += "set PATH=#{devtdir}/bin;%PATH% \n"
commands += "set TTBUILD=#{ttbuild} \n"
commands += "call #{qtdir}/bin/qtvars.bat vsvars\n"
commands += "call #{rubydir}/bin/rubyvars.bat \n"
commands += "qmake.exe "
commands += "-tp vc -nodepend -norecursive -nomoc -spec #{mkspec} "
commands += pro_file
commands += "\n"
File.open(pro_dir + "/" + "UpdateVCProj.bat", 'w') {|f|
f.write(commands)
}
rescue => e
error_message("#{e.message}\n#{e.backtrace.join("\n")}",__FILE__,__LINE__)
end
]]>
</scriptdef>
I can't reproduce it with single ant script definition, I guess something
happen when using mutithread with ant, our solution has hundreds of projects,
many ant script with File operations report error saying "Bad file descriptor".
