--------------------------------------
Summary: GDK: eachDirRecurse and eachFileRecurse are NOT
depth-first
Key: GROOVY-8341
URL: https://issues.apache.org/jira/browse/GROOVY-8341
Project: Groovy
Issue Type: Bug
Components: groovy-jdk
Affects Versions: 2.4.11
Environment: Windows Linux
Reporter: Dirk Heinrichs
Priority: Minor
The documentation for those two methods states: "Sub-directories are
recursively searched in a depth-first fashion." But the result is NOT
depth-first, as the following example shows:
Given a directory tree of {code}/tmp
|-/foo
| |-/foo
| |-/bar
| |-/baz
|-/baz{code}
the following simple code {code}#!/usr/bin/groovy
File rootDir = new File(new URI('file:/tmp/foo'))
rootDir.eachDirRecurse {
println(it)
}{code}
gives this result {code}/tmp/foo/bar
/tmp/foo/bar/baz
/tmp/foo/bar/foo
/tmp/foo/bar/bar
/tmp/foo/baz{code}
while {code}% find /tmp/foo -depth -type d{code}
correctly gives {code}/tmp/foo/bar/baz
/tmp/foo/bar/foo
/tmp/foo/bar/bar
/tmp/foo/bar
/tmp/foo/baz
/tmp/foo{code}
