+// Image files are an alternate file format for storing classes and resources. The
+// goal is to supply file access which is faster and smaller than the jar format.
+// It should be noted that unlike jars, information stored in an image is in native
+// endian format. This allows the image to be mapped into memory without endian
+// translation. This also means that images are platform dependent.
+//
+// Image files are structured as three sections;
+//
+// +-----------+
+// | Header |
+// +-----------+
+// | |
+// | Index |
+// | |
+// +-----------+
+// | |
+// | |
+// | Resources |
+// | |
+// | |
+// +-----------+
+//
+// The header contains information related to identification and description of
+// contents.
+//
+// +-------------------------+
+// | Magic (0xCAFEDADA) |
+// +------------+------------+
+// | Major Vers | Minor Vers |
+// +------------+------------+
+// | Flags |
+// +-------------------------+
+// | Resource Count |
+// +-------------------------+
+// | Table Length |
+// +-------------------------+
+// | Attributes Size |
+// +-------------------------+
+// | Strings Size |
+// +-------------------------+
+//
+// Magic - means of identifying validity of the file. This avoids requiring a
+// special file extension.
+// Major vers, minor vers - differences in version numbers indicate structural
+// changes in the image.
+// Flags - various image wide flags (future).
+// Resource count - number of resources in the file.
+// Table length - the length of lookup tables used in the index.
+// Attributes size - number of bytes in the region used to store location attribute
+// streams.
+// Strings size - the size of the region used to store strings used by the
+// index and meta data.
+//
+// The index contains information related to resource lookup. The algorithm
+// used for lookup is "A Practical Minimal Perfect Hashing Method"
+// (http://homepages.dcc.ufmg.br/~nivio/papers/wea05.pdf). Given a path string
+// in the form /<module>/<package>/<base>.<extension> return the resource location
+// information;
+//
+// redirectIndex = hash(path, DEFAULT_SEED) % table_length;
+// redirect = redirectTable[redirectIndex];
+// if (redirect == 0) return not found;
+// locationIndex = redirect < 0 ? -1 - redirect : hash(path, redirect) % table_length;
+// location = locationTable[locationIndex];
+// if (!verify(location, path)) return not found;
+// return location;
+//
+// Note: The hash function takes an initial seed value. A different seed value
+// usually returns a different result for strings that would otherwise collide with
+// other seeds. The verify function guarantees the found resource location is
+// indeed the resource we are looking for.
+//
+// The following is the format of the index;
+//
+// +-------------------+
+// | Redirect Table |
+// +-------------------+
+// | Attribute Offsets |
+// +-------------------+
+// | Attribute Data |
+// +-------------------+
+// | Strings |
+// +-------------------+
+//
+// Redirect Table - Array of 32-bit signed values representing actions that
+// should take place for hashed strings that map to that
+// value. Negative values indicate no hash collision and can be
+// quickly converted to indices into attribute offsets. Positive
+// values represent a new seed for hashing an index into attribute
+// offsets. Zero indicates not found.
+// Attribute Offsets - Array of 32-bit unsigned values representing offsets into
+// attribute data. Attribute offsets can be iterated to do a
+// full survey of resources in the image. Offset of zero
+// indicates no attributes.
+// Attribute Data - Bytes representing compact attribute data for locations. (See
+// comments in ImageLocation.)
+// Strings - Collection of zero terminated UTF-8 strings used by the index and
+// image meta data. Each string is accessed by offset. Each string is
+// unique. Offset zero is reserved for the empty string.
+//
+// Note that the memory mapped index assumes 32 bit alignment of each component
+// in the index.
+//
+// Endianness of an image.
+// An image booted by hotspot is always in native endian. However, it is possible

+// Manage image file location attribute data. Within an image, a location's

+// 'length' less 1 (lower 3 bits of header) of bytes that follow containing the
+// attribute value. Attribute values present as most significant byte first.
+//
+// Ex. Container offset (ATTRIBUTE_OFFSET) 0x33562 would be represented as 0x22
+// (kind = 4, length = 3), 0x03, 0x35, 0x62.
+//
+// An attribute stream is terminated with a header kind of ATTRIBUTE_END (header
+// byte of zero.)
+//
+// ImageLocation inflates the stream into individual values stored in the long
+// array _attributes. This allows an attribute value can be quickly accessed by
+// direct indexing. Unspecified values default to zero.
+//
+// Notes:
+// - Even though ATTRIBUTE_END is used to mark the end of the attribute stream,
+// streams will contain zero byte values to represent lesser significant bits.
+// Thus, detecting a zero byte is not sufficient to detect the end of an attribute
+// stream.
+// - ATTRIBUTE_OFFSET represents the number of bytes from the beginning of the region
+// storing the resources. Thus, in an image this represents the number of bytes
+// after the index.
+// - Currently, compressed resources are represented by having a non-zero
+// ATTRIBUTE_COMPRESSED value. This represents the number of bytes stored in the
+// image, and the value of ATTRIBUTE_UNCOMPRESSED represents number of bytes of the
+// inflated resource in memory. If the ATTRIBUTE_COMPRESSED is zero then the value
+// of ATTRIBUTE_UNCOMPRESSED represents both the number of bytes in the image and
+// in memory. In the future, additional compression techniques will be used and
+// represented differently.

- The following code performs a similar trick for RMI/IIOP to the
- one described above for RMI/JRMP. Unlike JRMP, though, we
- can't easily insert an object between the RMIConnection stub
- and the RMI/IIOP deserialization code, as explained below.
-
- A method in an RMI/IIOP stub does the following. It makes an
- org.omg.CORBA_2_3.portable.OutputStream for each request, and
- writes the parameters to it. Then it calls
- _invoke(OutputStream) which it inherits from CORBA's
- ObjectImpl. That returns an
- org.omg.CORBA_2_3.portable.InputStream. The return value is
- read from this InputStream. So the stack during
- deserialization looks like this:
-
- MBeanServerConnection.getAttribute (or whatever)
- -> _RMIConnection_Stub.getAttribute
- -> Util.readAny (a CORBA method)
- -> InputStream.read_any
- -> internal CORBA stuff
-
- What we would have *liked* to have done would be the same thing
- as for RMI/JRMP. We create a "ProxyDelegate" that is an
- org.omg.CORBA.portable.Delegate that simply forwards every
- operation to the real original Delegate from the RMIConnection
- stub, except that the InputStream returned by _invoke is
- wrapped by a "ProxyInputStream" that is loaded by our
- NoCallStackClassLoader.
-
- Unfortunately, this doesn't work, at least with Sun's J2SE
- 1.4.2, because the CORBA code is not designed to allow you to
- change Delegates arbitrarily. You get a ClassCastException
- from code that expects the Delegate to implement an internal
- interface.
-
- So instead we do the following. We create a subclass of the
- stub that overrides the _invoke method so as to wrap the
- returned InputStream in a ProxyInputStream. We create a
- subclass of ProxyInputStream using the NoCallStackClassLoader
- and override its read_any and read_value(Class) methods.
- (These are the only methods called during deserialization of
- MBeanServerConnection return values.) We extract the Delegate
- from the original stub and insert it into our subclass stub,
- and away we go. The state of a stub consists solely of its
- Delegate.
-
- We also need to catch ApplicationException, which will encode
- any exceptions declared in the throws clause of the called
- method. Its InputStream needs to be wrapped in a
- ProxyInputSteam too.
-
- We override _releaseReply in the stub subclass so that it
- replaces a ProxyInputStream argument with the original
- InputStream. This avoids problems if the implementation of
- _releaseReply ends up casting this InputStream to an
- implementation-specific interface (which in Sun's J2SE 5 it
- does).
-
- It is not strictly necessary for the stub subclass to be loaded
- by a NoCallStackClassLoader, since the call-stack search stops
- at the ProxyInputStream subclass. However, it is convenient
- for two reasons. One is that it means that the
- ProxyInputStream subclass can be accessed directly, without
- using reflection. The other is that it avoids build problems,
- since usually stubs are created after other classes are
- compiled, so we can't access them from this class without,
- again, using reflection.
-
- The strings below encode the following two Java classes,
- compiled using javac -g:none.
