(1) Default heap limit to 75% of available address space.
(2) Limit GC marker threads to 4MB/8MB (32bit vs 64bit) stack space.
As Mono tries to create 16 such threads by default, the default
stack size on AMD64 would eat 2GB VA alone.
Bump revision.

Also: general patch refresh
Upstream release notes:
Mono 3.10.0 is a bugfix release with a few features.
Highlights
Implemented System.IO.Compression.FileSystem.
Uri now implements the .NET 4.5 behavior, it can be reverted to
the old behavior in the same way by setting the System.Uri::s_IriParsing
static field to false.
Performance
Remove unnecessary locking from core metadata parsing functions.
Avoid cache thrashing of locals array when looping over enumerator.
Known Issues
The OSX packages have an invalid libgdiplus library that affects
users of System.Drawing that requires it to work.
This specially affects Xamarin.Mac users that fit the following criteria:
Uses Xamarin.Mac Classic (Unified is unaffected).
Uses the subsets of System.Drawing that use libgdiplus.dylib internally
- System.Drawing.RectangleF, PointF, Colors are unaffected
- System.Drawing.Bitmap, and font for example are affected
The symptom of the problem is your application failing with:
“System.TypeInitializationException: An exception was thrown by
the type initializer for
System.Drawing.GDIPlus —> System.Exception: GdiplusStartup”
Bug fixes
+++++++++
Runtime
Fix support for unaligned offsets in the store_membase_imm opcodes.

the class has the attribute XmlSchemeProvider and IsAny is true.
Fixes #11916
Test that DeflateStream.Read does read an empty stream. Covers #19313.
Reseting all private key values to null is required because a new
import may not overwrite existing values. Fixes #18482.

------------------------------------------------------------------------
Mono 3.8.0 has 711 commits since the last release.
This is the work of 61 contributors since May 28. 58 bugs were fixed.
Highlights
Major performance and scalability improvements across the the whole runtime.
Finished the Windows 64 port.
Debugger wire protocol optimized for usb connections.
Debugger
Updated wire protocol better handles high latency connections such
as those found when doing USB debugging.
Client library now aggressively caches information and batches
requests. Under one test scenario single stepping packets
transmitted dropped from 2233 to only 16, with the latency going
from seconds to 20 milliseconds.
Performance
The JIT now better handles long remainders by powers of two,
generating significantly better code.
Over 10x faster code is generated for delegates that are only
invoked once. C# features such as async and LINQ produce a lot of
those delegates, so this improvement will impact everyone.
Improved alias analysis can now handle second order aliases and
eliminate null checks.
The runtime now has a concurrently readable hashtable that can
makes reflection heavy workloads significantly faster and more scalable.
Garbage Collection
Optimized one of the core data structures of the garbage collector;
should result in 5-10% reduction in collection times.

Mono 3.6.0 has 878 commits since the last release. This is the work
of 66 contributors since March 10 2014. Out of those, 22 have done
their first contribution. 112 bugs were fixed.
Highlights
Runtime performance counters have been integrated into the
profiler allowing the performance counter information to be
surfaced to profiling tools and in particular Xamarinâs upcoming
profiler.
The profiler now produces backtraces for statistical mode. The
profilerâs tracing mode now works on ARM.
We now distribute nuget on mac.
Debugger
The debugger now support line and column ranges. pdb2mdb supports
it. Note: the rest of our toolchain still needs to be updated.
The debugger now supports changing the current line in the top
frame.
Lots of bugfixes and performance improvements.
The debugger now support reading simple properties without
calling their getter, this is done by having a lightweight IL
interpreter for small pieces of code. This allows more properties
to be inspected while the process is completely stopped and
without having to temporarily resume execution of the target
to execute the property code.
Added buffered response mode to improve network efficiency on
high latency links such as USB.
Garbage Collection
The GC bridge got a lot of performance work. There are now two
new modes that can significantly improve some workloads.
Class libraries
Multiple http stack improvements: some leaks in the stack have
been fixed, as well as solving some long-standing bugs involving
asynchronous operations and proxies. We have introduced a more
comprehensive test harness to ensure that those bugs do not
surface again.
System.IO.Compression is now implemented
System.Security.Claims is now implemented. It resides in the
System assembly (existed before in the Identity stack, but now
we track the new home from the .NET 4.5 API).
Performance
Reworked locking to drop a hot lock in method lookup.
Use fine grained locking instead of a big hot lock.
Better hashing of some runtime internal items to avoid some
corner-case slowdowns with generics.
Profiler
The profiler is now able to produces backtraces in statistical
mode.
Added periodical flushing that should help interactive users.
This means that the profiling will send data over the profiling
even if the application is not currently sending data (this is
there to support the upcoming new profiler UI).
It now collects and reports performance counter information.
See mprof-reportâs man page.
Misc
Fixed the handling of the volatile. CIL prefix.
We now distribute IKVMâs ikdasm tool. This is a reliable
disassembler that does not have the limitation of monodis of
requiring a complete set of assemblies that are compatible to
disassemble. This will disassemble even files that do not have
their dependencies available.
Optimized EqualityComparer for more types.
Mono.Unix.Native.Syscall.getxattr() can now return Errno.ENOATTR
on OS X.
Our msbuild implementation can now build Project K and Roslyn
Optimized EqualityComparer for more types.
As well as lots of bug fixes

Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.

python3, since the default changed from python33 to python34.
I probably bumped too many. I hope I got them all.

Reported crufty by Iain Morgan <Iain.Morgan@nasa.gov> on pkgsrc-users.
|
|
|
|
Setting PLATFORM causes the build system to look for a ${PLATFORM}.make
file; this leads to build failure if a PLATFORM environment variable
leaks in from the outside environment.

The latter contains the unstable version 3 of mono, which breaks many mono
packages.
Bump dependencies and PKGREVISIONs.
Ok during freeze: gdt@
|
|
This gets us a working mono package on SmartOS, at least.
|
|
and able to run the compiler, now failing in the documentation generator.
|
|
being able to run the bootstrap compiler, but for some as-yet unknown
reason it fails during the build but works ok when executed manually.
|
|
a) refer 'perl' in their Makefile, or
b) have a directory name of p5-*, or
c) have any dependency on any p5-* package
Like last time, where this caused no complaints.

in Mono 3.0.2
We are now on a cadence to deliver new Mono features and updates
on a regular basis. A month after our last release we are now
bringing some 363 commits, with 3055 files changed, 171240
insertions(+), 179104 deletions(-) Major Features
'Reactive Extensions': Mono now bundles the open sourced Microsoft's
Reactive Extensions
F# 3.0: We have updated the bundled F# compiler on OSX to version
3.0 (tag 3.0.22 from the open source fsharp repository).
SGen Garbage Collector: new lazy sweep strategy in Mono's new GC
that reduces the GC times for major collections significantly. We
have also tuned and improved the collector.
System.Json: We reverted System.Json to Mono's version, as it was
lighter and tolerates more input than Microsoft's one. We ship
System.Json.Microsoft as well for users that want to use the
Microsoft stack.
Runtime: Many improvements to Mono, better x86 and ARM support
across the board.
NTLM: Large upgrade to our NTLM stack.
clang: Mono now builds with Clang.

New in Mono 3.0 Major Highlights C# Compiler
Mono now has a complete C# 5.0 compiler with asynchronous programming
support.
Our C# compiler has now completed its migration from using
System.Reflection.Emit as its code generation backend to use the
IKVM.Reflection API. This functionality was previewed in Mono 2.10
and is now the default. With this functionality, developers can
use any mscorlib that they want (for example the MicroFramework
one, or a custom one) without having to build a custom compiler.
We were able to eliminate the multiple executables for the compiler,
and unify all the compilers into one as well as reducing our build
times significantly.
gmcs, dmcs and smcs are now merely aliases to call the mcs compiler
with the proper -sdk flag. Tool/Library Purpose Profile
New Backend 2.10 Backend gmcs C# Compiler 2.0
IKVM.Reflection System.Reflection 2.0 dmcs C# compiler
4.0 IVKM.Reflection System.Reflection 4.0 smcs C#
Compiler 2.1 (Silverlight, MonoTouch, MonoDroid)
IKVM.Reflection System.Reflection 2.0 mcs C# Compiler
Any profile, any mscorlib IKVM.Reflection IKVM.Reflection
csharp Interactive C# Shell/REPL 4.5 System.Reflection
4.5 System.Reflection 4.0 Mono.CSharp C# Compiler as a Service
2.0, 2.1 and 4.0. System.Reflection 4.0 System.Reflection
System.Reflection is still used as a backend for the compiler as
a service and the C# interactive shell. Evaluation can now Compile
Types
The Evaluator.Eval () API is no longer limited to expressions and
statements, you can now pass entire namespace, class, interface,
struct definitions as a string and have the result get compiled.
This extends to the csharp command:
csharp> class X { public int a; } csharp> var t = new X () { a =
1 }; csharp> print (t.a); 1 csharp>
Instance API
The compiler as a service exposed by the Mono.CSharp library is no
longer limited to be a global compiler, now you can instantiate
multiple scopes for the compiler, each having its own set of
localized types and global variables.
For example, the following sample assigns a string in one context
and an int in another one:
using System; using Mono.CSharp;
class MyWorld {
public Evaluator Evaluator;
public MyWorld (string [] args) {
var r = new Report (new ConsoleReportPrinter ());
var cmd = new CommandLineParser (r);
var settings = cmd.ParseArguments (args); if (settings
== null || r.Errors > 0)
Environment.Exit (1);
Evaluator = new Evaluator (settings, r); } }
class X {
static int Main (string [] args) {
var first = new MyWorld (args); var second = new
MyWorld (args);
first.Evaluator.Run ("var Demo = \"hello, world\";");
second.Evaluator.Run ("var Demo = 1;"); first.Evaluator.Run
("print (Demo);"); second.Evaluator.Run ("print
(Demo);"); return 0; } }
C# Interactive Shell
New convenience function print, can be used instead of Console.WriteLine
Additionally, the C# interactive shell will by default use a terse
syntax that does not require a semicolon at the end of an expression,
for example:
csharp> 1 + 2 3 csharp>
4.5 Profile
The 4.5 Profile is a strict superset of the 4.0 API and is now the
default profile.
Because 4.5 API is a strict superset of 4.0 API they both share
the same assembly version number, so we actually install the 4.5
library into the GAC.
Some of the changes in the 4.5 API family include:
New Async methods WinRT compatibility API Newly introduced
assemblies (System.Net.Http, System.Threading.Tasks.Dataflow)
New Microsoft Open Source Stacks
We now include the following assemblies as part of Mono from
Microsoft's ASP.NET WebStack:
System.Net.Http.Formatting.dll System.Web.Http.dll System.Web.Razor.dll
System.Web.WebPages.Deployment.dll System.Web.WebPages.Razor.dll
System.Web.WebPages.dll System.Web.Mvc.dll System.Json.dll
(Previously available in Mono, but now replaced with Microsoft's
implementation)
We also bundle the recently open sourced Entity Framework and
EntityFramework.dll
Garbage Collector
SGen now has a new task management system that allows it to easily
scale new GC-related tasks across multiple CPUs if available:
SGen on SMP systems is able to distribute more work across the
worker threads. Previously only the mark phase was distributed.
SGen is now able to perform parallel collection in the nursery.
SGen has been ported to Win32 SGen has been ported to the MIPS
platform Precise stack scanning has been improved considerably,
and it is now supported on x86 and ARM. On OSX, SGen now uses
Mach APIs directly to speedup some tasks in the garbage collector.
Runtime Optimizations
Implemented fast version of ThreadLocal<T> (it is now a low-level
intrinstic operation)
List<T> optimizations
Support for new attributes to force inlining.
Major change in Mono to support the full table of Unicode surrogate
characters. This code was written by Damien Diederen and David
Mitchell from Logos software.
Runtime supports deferred attaching to the process (when using
suspend=n,server=y the runtime collects metadata until a debugger
is attached).
Implement tail call optimizations on PowerPC for F# (Bug #664631)
New profiler that can be used with Intel's VTune Amplifier Profiler.
Support for System.Net.NetworkInformation.NetworkChanged events on
Linux.
New tool: crlupdate this is the Mono Certficate Revocation List
Downloader and Updater and can be used to download of new, or update
of existing, Certficate Revocation List (CRL) associated with the
certificates present in the user (default) or machine stores. The
CRL present in the stores are used to determine the validity of
unexpired, trusted X.509 certificates. ASP.NET
Bring the error page to the new millenium. CodeContracts
Alexander Chebaturkin has implemented initial version of static
Code Contract analyser as part of SoC 2011. Smaller Updates
Partial support for Portable Class Libraries (details)
Updated Unicode tables, fixes long-standing 480178 MacOS X
We continue to expand significantly our support for MacOS X and
iOS.
Mono can now be compiled by users as a 64-bit binary. Mono still
ships as a 32-bit binary, as most libraries that exist today for
Mono run only in 32 bits.
DriveInfo now returns correct information on OSX. Mono.Data.Sqlite
It is now possible to configure the threading model for SQLite
using the SetConfig method in the SQLiteConnection class.
Supports iOS crypto APIs. C5 Library
We have updated the venerable C5 library to the latest version.
Breaking Changes Since Mono 2.10
In order to be compatible with Microsoft .NET's behavior, exceptions
thrown in object finalizers now cause a full runtime abort. This
behavior was already present for thread pool threads, but hadn't
been enabled for the finalizer thread yet.
Generally, one should avoid exceptions in finalizers entirely. If
you must use them, catch them so that they do not terminate the
application. GDB
GDB support has been extended with a new gdb hook that is aware
of the SGenGC internals. Added pretty printers for more runtime
data structures like MonoVTable to the mono gdb mode.
MIPS port
The MIPS port is now complete, it can do a full bootstrap, and run
the runtime/corlib test suites. Soft Debugger
Single stepping is now implemented using breakpoints in most
cases, speeding it up considerably. Calls to
System.Diagnostics.Debugger:Log()/Break () are now routed to
the debugger using new UserLog/UserBreak event types. S390x
is now supported (Neale Ferguson). MIPS is now supported.
Added new methods to Mono.Debugger.Soft and the runtime to
decrease the amount of packets transmitted between the debugger
and the debuggee. This significantly improves performance over
high latency connections like USB. Many bug fixes.
Static Compiler (AOT)
Made changes to some AOT data structures to reduce their size,
especially when using generics. This reduces the size of an mscorlib
AOT image by about 1-2%.
Many changes to the class libraries allow more core Generics code
to run on systems that do not support JIT compilation.
