-
-2009-04-30  Sebastien Pouliot  <sebastien@ximian.com> 
-
-	* AuthenticodeBase.cs, AuthenticodeDeformatter.cs: Remove from NET_2_1
-
-2008-01-10  Sebastien Pouliot  <sebastien@ximian.com>
-
-	* AuthenticodeDeformatter.cs: Use RSAManaged and the new overloaded
-	PKCS1.Verify_v15 with tryNonStandardEncoding == true when verifying
-	timestamping certificate signatures. Fix for #350958
-
-2007-04-26  Sebastien Pouliot  <sebastien@ximian.com>

-
-2006-11-08  Sebastien Pouliot  <sebastien@ximian.com>
-
-	* AuthenticodeDeformatter.cs: Return (find) the SigningCertificate 
-	even if the signature isn't verifiable. This is the behaviour required
-	for 2.0.
-
-2006-06-14  Sebastien Pouliot  <sebastien@ximian.com>
-
-	* AuthenticodeBase.cs: Fix destination offset. Note that this works

-	/* NOTES
-	 * 
-	 * - There's NO confidentiality / integrity built in this
-	 * persistance mechanism. The container directories (both user and
-	 * machine) are created with restrited ACL. The ACL is also checked
-	 * when a key is accessed (so totally public keys won't be used).
-	 * see /mono/mono/metadata/security.c for implementation
-	 * 
-	 * - As we do not use CSP we limit ourselves to provider types (not 
-	 * names). This means that for a same type and container type, but 
-	 * two different provider names) will return the same keypair. This
-	 * should work as CspParameters always requires a csp type in its
-	 * constructors.
-	 * 
-	 * - Assert (CAS) are used so only the OS permission will limit access
-	 * to the keypair files. I.e. this will work even in high-security 
-	 * scenarios where users do not have access to file system (e.g. web 
-	 * application). We can allow this because the filename used is 
-	 * TOTALLY under our control (no direct user input is used).
-	 * 
-	 * - You CAN'T changes properties of the keypair once it's been
-	 * created (saved). You must remove the container than save it 
-	 * back. This is the same behaviour as CSP under Windows.

-2010-05-10  Sebastien Pouliot  <sebastien@ximian.com>
-
-	* ASN1.cs: Keep it public for Moonlight. Other types in other 
-	assemblies needs it and the linker will eventually internalize
-	everything.
-
-2010-03-24  Sebastien Pouliot  <sebastien@ximian.com>
-
-	* ASN1Convert.cs: Specify CultureInfo.InvariantCulture (instead of 
-	null) to avoid crash on Windows. Patch by Yoni Shalom.
-
-2010-03-16  Jb Evain  <jbevain@novell.com>
-
-	* StrongName.cs: use MOONLIGHT symbol to disambiguate
-	MonoTouch and Moonlight code.
-
-2009-09-22  Sebastien Pouliot  <sebastien@ximian.com> 
-
-	* StrongName.cs: Moonlight NET_2_1 cannot depend on machine.config
-	* StrongNameManager_2_1.cs: Minimal version for NET_2_1
-
-2009-04-30  Sebastien Pouliot  <sebastien@ximian.com> 
-
-	* StrongName.cs: Adapt to work with only RSAManaged when built 
-	for NET_2_1, i.e. remove use of RSACryptoServiceProvider
-
-2008-09-12  Sebastien Pouliot  <sebastien@ximian.com>
-
-	* ASN1.cs: Use File.Create instead of OpenWrite to make sure nothing
-	else if left at the end of the file.
-
-2008-04-25  Sebastien Pouliot  <sebastien@ximian.com>
-
-	* StrongName.cs: New test cases to verify signatures from streams.
-	Patch from Dave Hillier <daveh@lindenlab.com>
-
-2008-03-10  Stephane Delcroix  <sdelcroix@novell.com>
-
-	* Uri.cs: port the changes I did in System.Uri in r97844.
-
-2007-03-11  Zoltan Varga  <vargaz@gmail.com>
-
-	* ASN1Convert.cs: Fix a warning.
-
-2007-02-12  Sebastien Pouliot  <sebastien@ximian.com>
-
-	* ASN1Convert.cs: Add support for decoding ASN.1 dates with an UTC 
-	offset (e.g. 990630000000+1000) as some certificates use this format.
-
-2007-01-05  Sebastien Pouliot  <sebastien@ximian.com>
-
-	* ASN1Convert.cs: Added comment to FromDateTime to specify that, under
-	1.x, the DateTime must be a local (not UTC) date time. Fixed ToDateTime
-	to return a DateTimeKind.Utc DateTime under 2.0.
-
-2006-08-17  Sebastien Pouliot  <sebastien@ximian.com>
-
-	* StrongName.cs: Fix the (very unlikely) case where an MD5 public key
-	token is requested (part of the spec, never seen in the wild).
-
-2006-06-14  Sebastien Pouliot  <sebastien@ximian.com>
-
-	* ASN1.cs: Switch condition not to use the cached data if there is a
-	collection being used. Skip extra 0 at the end of the byte[] buffer.
-
-2006-01-04  Sebastien Pouliot  <sebastien@ximian.com>
-
-	* ASN1Convert.cs: Fix convertion of integer 0 to ASN.1.
-
-2005-11-07  Sebastien Pouliot  <sebastien@ximian.com>

-	* StrongName.cs: Synch with Mono.Security.dll to get support for 
-	strongname keypairs different from 1024 bits.
-
-2005-10-06  Sebastien Pouliot  <sebastien@ximian.com>
-
-	* ASN1Convert.cs: Better handle big integer than cannot be interpreted

-2004-12-15  Sebastien Pouliot  <sebastien@ximian.com>
-
-	* ASN1.cs: Fixed warning for unused variable.
-

-
-	* ASN1.cs: Throw an NotSupportedException when "undefined length 
-	encoding" is used (#68903 but it's not a fix ;-). Fixed GetBytes to
-	encode structures bigger than 64k (fix #68907). Simplified ToString
-	and added Length to help debugging.
-	* PKCS7.cs: Added a flag to avoid resigning a structure (which was
-	duplicating some attributes).
-
-2004-09-16  Sebastien Pouliot  <sebastien@ximian.com>
-
-	* ASN1.cs: Fixed warning (l4) for unused variable.

-	class to reduce number of warnings.
-
-2004-08-30  Sebastien Pouliot  <sebastien@ximian.com>
-
-	* Uri.cs: Copied from System.dll assembly and started adaptation for
-	it's reuse inside the security classes (CAS).
-
-2004-06-08  Sebastien Pouliot  <sebastien@ximian.com>
-
-	* StrongName.cs: Added corlib specific code to load configuration
-	from machine.config to allow public key token remapping to work

-2004-03-31  Sebastien Pouliot  <sebastien@ximian.com>
-
-	* StrongName.cs: Update to include new static method that can be 
-	called from the runtime to validate strongname signatures. 
-	Refactored the existing class to reduce code duplication.
-	* StrongNameManager.cs: New. This class keeps the configuration
-	required to map a public key token to an alternative public key
-	(e.g. ECMA public key token -> Mono public key) and to skip
-	strongname validation for specific assemblies/token/users.
-
-2004-03-24  Sebastien Pouliot  <sebastien@ximian.com>
-
-	* StrongName.cs: Added CanSign property for AssemblyBuilder. Current
-	Fx design requires an exception to know if the private key is present
-	in an RSA instance. In some case (inside corlib) we can do without...

-
-2003-03-15  Sebastien Pouliot  <spouliot@videotron.ca>
-
-	* ASN1.cs: Improved version.
-	* ASN1Convert.cs: New. Helper class to convert between .NET 
-	types and ASN.1 structures.

+// The main differences with mono-api-diff are:
+// * this tool directly produce HTML similar to gdiff.sh used for Xamarin.iOS
+// * this tool reports changes in an "evolutionary" way, not in a breaking way,
+//   i.e. it does not assume the source assembly is right (but simply older)
+// * the diff .xml output was not easy to convert back into the HTML format
+//   that gdiff.sh produced

+	 * which SGen chokes on.  The race condition is triggered infrequently by
+	 * `tests/sgen-suspend.cs`.
+	 *
+	 * This function is called for a class whenever one of its subclasses is inited.
+	 * For example, it's called for every subclass of Object.  What it does is this:

+	 *
+	 * The last two steps are sometimes reversed, but that only changes the way in which
+	 * the race condition works.
+	 *
+	 * Assume thread A goes through this function and makes it to the critical point.
+	 * Now thread B runs the function and, since `setup_fields_called` is set, returns
+	 * immediately, but `instance_size` is incorrect.
+	 *
+	 * The other case looks like this:
+	 *
+	 *     if (class->setup_fields_called)
+	 *         return;
+	 *     ... critical point X
+	 *     class->instance_size = 0;

+	 *     ...
+	 *     class->setup_fields_called = 1;
+	 *
+	 * Assume thread A goes through the function and makes it to critical point X.  Now
+	 * thread B runs through the whole of the function, returning, assuming
+	 * `instance_size` is set.  At that point thread A gets to run and makes it to
+	 * critical point Y, at which time `instance_size` is `0` again, invalidating thread

+/*
+ * We're using (mostly) non-locking staging queues for finalizers and weak links to speed
+ * up registering them.  Otherwise we'd have to take the GC lock.
+ *
+ * The queues are arrays of `StageEntry`, plus a `next_entry` index.  Threads add entries to
+ * the queue via `add_stage_entry()` in a linear fashion until it fills up, in which case
+ * `process_stage_entries()` is called to drain it.  A garbage collection will also drain
+ * the queues via the same function.  That implies that `add_stage_entry()`, since it
+ * doesn't take a lock, must be able to run concurrently with `process_stage_entries()`,
+ * though it doesn't have to make progress while the queue is drained.  In fact, once it
+ * detects that the queue is being drained, it blocks until the draining is done.
+ *
+ * The protocol must guarantee that entries in the queue are causally ordered, otherwise two
+ * entries for the same location might get switched, resulting in the earlier one being
+ * committed and the later one ignored.
+ *
+ * `next_entry` is the index of the next entry to be filled, or `-1` if the queue is
+ * currently being drained.  Each entry has a state:
+ *
+ * `STAGE_ENTRY_FREE`: The entry is free.  Its data fields must be `NULL`.
+ *
+ * `STAGE_ENTRY_BUSY`: The entry is currently being filled in.
+ *
+ * `STAGE_ENTRY_USED`: The entry is completely filled in and must be processed in the next
+ * draining round.
+ *
+ * `STAGE_ENTRY_INVALID`: The entry was busy during queue draining and therefore
+ * invalidated.  Entries that are `BUSY` can obviously not be processed during a drain, but
+ * we can't leave them in place because new entries might be inserted before them, including
+ * from the same thread, violating causality.  An alternative would be not to reset
+ * `next_entry` to `0` after a drain, but to the index of the last `BUSY` entry plus one,
+ * but that can potentially waste the whole queue.
+ *
+ * State transitions:
+ *
+ * | from    | to      | filler? | drainer? |
+ * +---------+---------+---------+----------+
+ * | FREE    | BUSY    | X       |          |
+ * | BUSY    | FREE    | X       |          |
+ * | BUSY    | USED    | X       |          |
+ * | BUSY    | INVALID |         | X        |
+ * | USED    | FREE    |         | X        |
+ * | INVALID | FREE    | X       |          |
+ *
+ * `next_entry` can be incremented either by the filler thread that set the corresponding
+ * entry to `BUSY`, or by another filler thread that's trying to get a `FREE` slot.  If that
+ * other thread wasn't allowed to increment, it would block on the first filler thread.
+ *
+ * An entry's state, once it's set from `FREE` to `BUSY` by a filler thread, can only be
+ * changed by that same thread or by the drained.  The drainer can only set a `BUSY` thread
+ * to `INVALID`, so it needs to be set to `FREE` again by the original filler thread.

-# S/390 64-bit cpu description file
-# this file is read by genmdesc to pruduce a table with all the relevant information
-# about the cpu instructions that may be used by the regsiter allocator, the scheduler
-# and other parts of the arch-dependent part of mini.
-#
-# An opcode name is followed by a colon and optional specifiers.
-# A specifier has a name, a colon and a value. Specifiers are separated by white space.
-# Here is a description of the specifiers valid for this file and their possible values.
-#
-# dest:register       describes the destination register of an instruction
-# src1:register       describes the first source register of an instruction
-# src2:register       describes the second source register of an instruction
-#
-# register may have the following values:
-#	i  integer register
-#	a  r3 register (output from calls)
-#	b  base register (used in address references)
-#	f  floating point register
-#
-# len:number         describe the maximun length in bytes of the instruction
-# number is a positive integer
-#
-# cost:number        describe how many cycles are needed to complete the instruction (unused)
-#
-# clob:spec          describe if the instruction clobbers registers or has special needs
-#
-# spec can be one of the following characters:
-#	c  clobbers caller-save registers
-#	r  'reserves' the destination register until a later instruction unreserves it
-#          used mostly to set output registers in function calls
-#
-# flags:spec        describe if the instruction uses or sets the flags (unused)
-#
-# spec can be one of the following chars:
-# 	s  sets the flags
-#       u  uses the flags
-#       m  uses and modifies the flags
-#
-# res:spec          describe what units are used in the processor (unused)
-#
-# delay:            describe delay slots (unused)
-#
-# the required specifiers are: len, clob (if registers are clobbered), the registers
-# specifiers if the registers are actually used, flags (when scheduling is implemented).
-#
-# See the code in mini-x86.c for more details on how the specifiers are used.

+5)lock M
+
+Say (1) happens before (5) and (5) happens before (2).
+This means that thread 2 was suspended by the kernel because
+it's waiting on mutext M.
+
+Thread 1 then proceed to suspend thread 2 and unlock/lock the
+mutex.
+
+If the kernel implements mutexes with FIFO wait lists, this means
+that thread 1 will be blocked waiting for thread 2 acquire the lock.
+Since thread 2 is suspended, we have a deadlock.
+
+A suspend safe mutex is an unfair lock but will schedule any runable
+thread that is waiting for a the lock.
+
+This problem was witnessed on OSX in mono/tests/thread-exit.cs.
