+# Makefile for building sunec.jar and sunecc native library.
+#
+# This file was derived from make/com/sun/crypto/provider/Makefile.
+#
+
+#
+# (The terms "OpenJDK" and "JDK" below refer to OpenJDK and Sun JDK builds
+# respectively.)
+#
+# JCE builds are very different between OpenJDK and JDK. The OpenJDK JCE
+# jar files do not require signing, but those for JDK do. If an unsigned
+# jar file is installed into JDK, things will break when the crypto
+# routines are called.
+#
+# This Makefile does the "real" build of the JCE files. For OpenJDK,
+# the jar files built here are installed directly into the OpenJDK.
+#
+# For JDK, the binaries use pre-built/pre-signed binary files stored in
+# the closed workspace that are not shipped in the OpenJDK workspaces.
+# We still build the JDK files here to verify the files compile, and in
+# preparation for possible signing. Developers working on JCE in JDK
+# must sign the JCE files before testing. The JCE signing key is kept
+# separate from the JDK workspace to prevent its disclosure.
+#
+# SPECIAL NOTE TO JCE/JDK developers: The source files must eventually
+# be built, signed, and then the resulting jar files MUST BE CHECKED
+# INTO THE CLOSED PART OF THE WORKSPACE*. This separate step *MUST NOT
+# BE FORGOTTEN*, otherwise a bug fixed in the source code will not be
+# reflected in the shipped binaries. The "release" target should be
+# used to generate the required files.
+#
+# There are a number of targets to help both JDK/OpenJDK developers.
+#
+# Main Targets (JDK/OPENJDK):
+#
+# all/clobber/clean The usual, plus the native libraries.
+# If OpenJDK, installs sunec.jar.
+# If JDK, installs prebuilt
+# sunec.jar.
+#
+# jar Builds/installs sunec.jar
+# If OpenJDK, does not sign.
+# If JDK, tries to sign.
+#
+# Other lesser-used Targets (JDK/OPENJDK):
+#
+# build-jar Builds sunec.jar
+# (does not sign/install)
+#
+# install-jar Alias for "jar" above.
+#
+# Other targets (JDK only):
+#
+# sign Alias for sign-jar
+# sign-jar Builds/signs sunec.jar (no install)
+#
+# release Builds all targets in preparation
+# for workspace integration.
+#
+# install-prebuilt Installs the pre-built jar files
+#
+# This makefile was written to support parallel target execution.

+ * when the input array is partially sorted, while offering the
+ * performance of a traditional mergesort when the input array is

+ * input arrays to n/2 object references for randomly ordered input
+ * arrays.

- * The sorting algorithm is a modified mergesort (in which the merge is

+ * A stable, adaptive, iterative mergesort that requires far fewer than
+ * n lg(n) comparisons when running on partially sorted arrays, while
+ * offering performance comparable to a traditional mergesort when run
+ * on random arrays. Like all proper mergesorts, this sort is stable and
+ * runs O(n log n) time (worst case). In the worst case, this sort requires
+ * temporary storage space for n/2 object references; in the best case,
+ * it requires only a small constant amount of space.
+ *
+ * This implementation was adapted from Tim Peters's list sort for
+ * Python, which is described in detail here:
+ *
+ * http://svn.python.org/projects/python/trunk/Objects/listsort.txt

+ * Peter McIlroy
+ * SODA (Fourth Annual ACM-SIAM Symposium on Discrete Algorithms),
+ * pp 467-474, Austin, Texas, 25-27 January 1993.
+ *
+ * While the API to this class consists solely of static methods, it is
+ * (privately) instantiable; a TimSort instance holds the state of an ongoing

- * fields to null. The normal queue operations unlink but then
- * pass over nodes with null item fields. Similarly, iteration
- * methods ignore those with nulls.
+ * This is a modification of the Michael & Scott algorithm,
+ * adapted for a garbage-collected environment, with support for
+ * interior node deletion (to support remove(Object)). For
+ * explanation, read the paper.
*
- * Also note that like most non-blocking algorithms in this

+ * Note that like most non-blocking algorithms in this package,
+ * this implementation relies on the fact that in garbage
* collected systems, there is no possibility of ABA problems due
* to recycled nodes, so there is no need to use "counted
* pointers" or related techniques seen in versions used in
* non-GC'ed settings.
+ *
+ * The fundamental invariants are:
+ * - There is exactly one (last) Node with a null next reference,
+ * which is CASed when enqueueing. This last Node can be
+ * reached in O(1) time from tail, but tail is merely an
+ * optimization - it can always be reached in O(N) time from
+ * head as well.
+ * - The elements contained in the queue are the non-null items in
+ * Nodes that are reachable from head. CASing the item
+ * reference of a Node to null atomically removes it from the
+ * queue. Reachability of all elements from head must remain
+ * true even in the case of concurrent modifications that cause
+ * head to advance. A dequeued Node may remain in use
+ * indefinitely due to creation of an Iterator or simply a
+ * poll() that has lost its time slice.
+ *
+ * The above might appear to imply that all Nodes are GC-reachable
+ * from a predecessor dequeued Node. That would cause two problems:
+ * - allow a rogue Iterator to cause unbounded memory retention
+ * - cause cross-generational linking of old Nodes to new Nodes if
+ * a Node was tenured while live, which generational GCs have a
+ * hard time dealing with, causing repeated major collections.
+ * However, only non-deleted Nodes need to be reachable from
+ * dequeued Nodes, and reachability does not necessarily have to
+ * be of the kind understood by the GC. We use the trick of
+ * linking a Node that has just been dequeued to itself. Such a
+ * self-link implicitly means to advance to head.
+ *
+ * Both head and tail are permitted to lag. In fact, failing to
+ * update them every time one could is a significant optimization
+ * (fewer CASes). This is controlled by local "hops" variables
+ * that only trigger helping-CASes after experiencing multiple
+ * lags.
+ *
+ * Since head and tail are updated concurrently and independently,
+ * it is possible for tail to lag behind head (why not)?
+ *
+ * CASing a Node's item reference to null atomically removes the
+ * element from the queue. Iterators skip over Nodes with null
+ * items. Prior implementations of this class had a race between
+ * poll() and remove(Object) where the same element would appear
+ * to be successfully removed by two concurrent operations. The
+ * method remove(Object) also lazily unlinks deleted Nodes, but
+ * this is merely an optimization.
+ *
+ * When constructing a Node (before enqueuing it) we avoid paying
+ * for a volatile write to item by using lazySet instead of a
+ * normal write. This allows the cost of enqueue to be
+ * "one-and-a-half" CASes.
+ *
+ * Both head and tail may or may not point to a Node with a
+ * non-null item. If the queue is empty, all items must of course
+ * be null. Upon creation, both head and tail refer to a dummy
+ * Node with null item. Both head and tail are only updated using
+ * CAS, so they never regress, although again this is merely an
+ * optimization.

+ * {@code JLayer} is a universal decorator for Swing components
+ * which enables you to implement various advanced painting effects as well as
+ * receive notifications of all {@code AWTEvent}s generated within its borders.
+ * <p/>
+ * {@code JLayer} delegates the handling of painting and input events to a
+ * {@link javax.swing.plaf.LayerUI} object, which performs the actual decoration.
+ * <p/>
+ * The custom painting implemented in the {@code LayerUI} and events notification
+ * work for the JLayer itself and all its subcomponents.
+ * This combination enables you to enrich existing components
+ * by adding new advanced functionality such as temporary locking of a hierarchy,
+ * data tips for compound components, enhanced mouse scrolling etc and so on.
+ * <p/>
+ * {@code JLayer} is a good solution if you only need to do custom painting
+ * over compound component or catch input events from its subcomponents.
+ * <pre>
+ * // create a component to be decorated with the layer
+ * JPanel panel = new JPanel();
+ * panel.add(new JButton("JButton"));
+ * // This custom layerUI will fill the layer with translucent green
+ * // and print out all mouseMotion events generated within its borders
+ * LayerUI<JPanel> layerUI = new LayerUI<JPanel>() {
+ * public void paint(Graphics g, JCompo nent c) {
+ * // paint the layer as is
+ * super.paint(g, c);
+ * // fill it with the translucent green
+ * g.setColor(new Color(0, 128, 0, 128));
+ * g.fillRect(0, 0, c.getWidth(), c.getHeight());
+ * }
+ * // overridden method which catches MouseMotion events
+ * public void eventDispatched(AWTEvent e, JLayer<JPanel> l) {

+ * // create the layer for the panel using our custom layerUI

- * (Hopefully temporarily) disable the clone-exec feature pending
- * further investigation and bug-fixing.
- * 32-bit (but not 64-bit) Linux fails on the program
- * Runtime.getRuntime().exec("/bin/true").waitFor();
- * with:
- * # Internal Error (os_linux_x86.cpp:683), pid=19940, tid=2934639536
- * # Error: pthread_getattr_np failed with errno = 3 (ESRCH)
- * Linux kernel/pthread gurus are invited to figure this out.
+ * There are 3 possible strategies we might use to "fork":
+ *
+ * - fork(2). Very portable and reliable but subject to
+ * failure due to overcommit (see the documentation on
+ * /proc/sys/vm/overcommit_memory in Linux proc(5)).
+ * This is the ancient problem of spurious failure whenever a large
+ * process starts a small subprocess.
+ *
+ * - vfork(). Using this is scary because all relevant man pages
+ * contain dire warnings, e.g. Linux vfork(2). But at least it's
+ * documented in the glibc docs and is standardized by XPG4.
+ * http://www.opengroup.org/onlinepubs/000095399/functions/vfork.html
+ * On Linux, one might think that vfork() would be implemented using
+ * the clone system call with flag CLONE_VFORK, but in fact vfork is
+ * a separate system call (which is a good sign, suggesting that
+ * vfork will continue to be supported at least on Linux).
+ * Another good sign is that glibc implements posix_spawn using
+ * vfork whenever possible. Note that we cannot use posix_spawn
+ * ourselves because there's no reliable way to close all inherited
+ * file descriptors.
+ *
+ * - clone() with flags CLONE_VM but not CLONE_THREAD. clone() is
+ * Linux-specific, but this ought to work - at least the glibc
+ * sources contain code to handle different combinations of CLONE_VM
+ * and CLONE_THREAD. However, when this was implemented, it
+ * appeared to fail on 32-bit i386 (but not 64-bit x86_64) Linux with
+ * the simple program
+ * Runtime.getRuntime().exec("/bin/true").waitFor();
+ * with:
+ * # Internal Error (os_linux_x86.cpp:683), pid=19940, tid=2934639536
+ * # Error: pthread_getattr_np failed with errno = 3 (ESRCH)
+ * We believe this is a glibc bug, reported here:
+ * http://sources.redhat.com/bugzilla/show_bug.cgi?id=10311
+ * but the glibc maintainers closed it as WONTFIX.
+ *
+ * Based on the above analysis, we are currently using vfork() on
+ * Linux and fork() on other Unix systems, but the code to use clone()
+ * remains.
