Unsafe VFS recursion
Reports usage of VirtualFile.getChildren()
inside recursive methods.
This may cause endless loops when iterating over cyclic symlinks. Use VfsUtilCore.visitChildrenRecursively()
instead.
void processDirectory(VirtualFile dir) {
for (VirtualFile file : dir.getChildren()) { // bad
if (!file.isDirectory()) {
processFile(file);
} else {
processDirectory(file); // recursive call
}
}
}
void processDirectory(VirtualFile dir) {
VfsUtilCore.visitChildrenRecursively(dir, new VirtualFileVisitor<Void>() { // good
@Override
public boolean visitFile(@NotNull VirtualFile file) {
if (!file.isDirectory()) {
processFile(file);
}
return true;
}
});
}
