From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- .../javax/net/ssl/provider/AbstractHandshake.java | 1205 +++++++++++++++++

Setter methods (usually in a class that implements the {@link Builder} + * interface) may modify the limit, but the general contract remains that + * the position remain at zero, and that the limit be at least as large as + * the object length. + * + *

Thus, very often the code will use absolute getters and setters + * for primitive types, or it will use the {@link java.nio.ByteBuffer#duplicate()} + * method, and sometimes the {@link java.nio.ByteBuffer#slice()} method, and + * will change the position or limit of the duplicate buffer. + */ +public interface Constructed +{ + /** + * Returns the total length, in bytes, of this structure. + * + * @return The length of this structure. + */ + int length(); + + /** + * Returns a printable representation of this structure, with the + * given prefix prepended to each line. + * + * @param prefix The prefix to prepend to each line of the + * output.

+    //
+    // So, we can have one of two states:
+    //
+    // 1) We have enough space in the record we are creating to push out
+    //    everything we need to on this round. This is easy; we just
+    //    repeatedly fill in these messages in the buffer, so we get something
+    //    that looks like this:
+    //                 ________________________________
+    //       records: |________________________________|
+    //    handshakes: |______|__|__________|
+    //
+    // 2) We can put part of one handshake message in the current record,
+    //    but we must put the rest of it in the following record, or possibly
+    //    more than one following record. So here, we'd see this:
+    //
+    //                 ________________________
+    //       records: |_______|_______|________|
+    //    handshakes: |____|_______|_________|
+    //
+    // We *could* make this a lot easier by just only ever emitting one
+    // record per call, but then we would waste potentially a lot of space
+    // and waste a lot of TCP packets by doing it the simple way. What
+    // we desire here is that we *maximize* our usage of the resources
+    // given to us, and to use as much space in the present fragment as
+    // we can.
+    //
+    // Note that we pretty much have to support this, anyway, because SSL
+    // provides no guarantees that the record size is large enough to
+    // admit *even one* handshake message. Also, callers could call on us
+    // with a short buffer, even though they aren't supposed to.
+    //
+    // This is somewhat complicated by the fact that we don't know, a priori,
+    // how large a handshake message will be until we've built it, and our
+    // design builds the message around the byte buffer.
+    //
+    // Some ways to handle this:
+    //
+    //  1. Write our outgoing handshake messages to a private buffer,
+    //     big enough per message (and, if we run out of space, resize that
+    //     buffer) and push (possibly part of) this buffer out to the
+    //     outgoing buffer. This isn't that great because we'd need to
+    //     store and copy things unnecessarily.
+    //
+    //  2. Build outgoing handshake objects 'virtually', that is, store them
+    //     as collections of objects, then compute the length, and then write
+    //     them to a buffer, instead of making the objects views on
+    //     ByteBuffers for both input and output. This would complicate the
+    //     protocol objects a bit (although, it would amount to doing
+    //     separation between client objects and server objects, which is
+    //     pretty OK), and we still need to figure out how exactly to chunk
+    //     those objects across record boundaries.
+    //
+    //  3. Try to build these objects on the buffer we're given, but detect
+    //     when we run out of space in the output buffer, and split the
+    //     overflow message. This sounds like the best, but also probably
+    //     the hardest to code.
