CKReleaser limits source and target directories too aggressively

[Clayton Coleman]

CKReleaser prevents the source and target directories from being different because io.isChildPath has an incorrect logical test. The default build (as specified in release.bat) works because target is a child path of source and because the _dev directory is ignored during copy.

Default command (from latest version of release.bat):

java -jar ckreleaser/ckreleaser.jar ckreleaser.release ../.. release "3.1 SVN" ckeditor_3.1_svn --run-before-release=langtool.bat

release.bat is in the <root>/_dev/releaser directory of the source tree, which means the source dir is <root> and the target directory is <root>/_dev/releaser/release

For 3rd parties using different build systems and different directory structures (for instance, where the build output must live in a directory outside of the source tree) it would be preferable to specify a command like:

java -jar ckreleaser/ckreleaser.jar customckreleaser.release path/to/ckeditor build/ckeditor <versionid> <filename>

Executing this command throws the exception:

Target directory must be located outside source directory

which is thrown by this line of releaser.js

468 if ( CKRELEASER.io.isChildPath( targetDir.getCanonicalPath(), sourceDir.getCanonicalPath() ) )
469 throw "Target directory must be located outside source directory";

This is incorrect - the target directory and source directory are not located underneath each other, which examination of isChildPath shows is because the return statement is too aggressive.

403 isChildPath : function( childPath, parentPath )
404 {
405 if ( childPath.length > parentPath.length )
406 return false;
407
408 var i = 0, max = Math.min( childPath.length(), parentPath.length() );
409
410 while ( i < max && childPath.charAt( i ) == parentPath.charAt( i ) )
411 i++;
412
413 return i != max;
414 }

If the working directory is c:\test, the source dir is c:\test\path\to\ckeditor, and the target dir is c:\test\build\ckeditor, then isChildPath should return false (the two are not child paths of each other). However, "return i != max" returns true for this scenario because the two paths match only up until character 7 (i == 7, max == 22). It should be "return i==max".

If isChildPath is adjusted to correctly check path parentage then ckreleaser can be used in different directory structures

The isChildPath() function was invalid.

Apart from that, theoretically, there should be something like

if (CKRELEASER.io.isChildPath(target, source) && !CKRELEASER.release.isIgnoredPath(target))
     throw "Target directory must be located outside the source directory";

to check whether target dir is ignored. If yes, then we should allow using target directory in the source directory (otherwise we'll not be able to create a release inside of the _dev folder).

In reality, the "isIgnoredPath" function works in a special way and cannot be called like that. Instead, we're looping through all ignored directories and checking whether the target directory is a child folder of one of the ignored folders.

[Clayton Coleman]

The provided JAR worked in the scenarios I needed - running in a working directory outside of source where target was a child of the working directory.

Thanks

Fixed with [4873].
