Mono 4.4.0 Release Notes
Our build system has been reconfigured to become a 4.x setup, as opposed to 4.5 only and it’s now tracking .NET 4.6.1 APIs.
Targeting earlier .NET profiles happens via so-called reference assemblies, which we introduced in Mono 4.0.
To make it more clear that these are just used for compilation and not
during runtime (they contain only metadata, no actual method IL),
we renamed the profile folders in
The folder structure on disk when installing Mono now looks like this:
<prefix>/lib/mono/ ├── 2.0-api ├── 3.5-api ├── 4.0-api ├── 4.5-api ├── 4.5 ...
4.5 folder contains the actual assemblies that are used
during runtime. We’re considering these the
latest assemblies from
now on, i.e. right now they’re implementing .NET 4.6.1.
Unfortunately, we couldn’t rename this folder as too many apps and
libraries hardcoded checks for this path.
WebHttpBinding must use http scheme in case when
The embedding API now has the following additions:
mini_parse_debug_optionallows embedders to set debug options programatically, without going through the
It is now possible to configure the runtime to generate LLVM bitcode
when passing the
--with-bitcode option to
configure. This mode of
operation avoids certain low-level optimizations that require assembly
code to be used and instead limits the runtime to use constructs that
can be expressed entirely in bitcode mode. This is designed to
support scenarios where you want to use LLVM to drive the entire
Unmanaged Thin Locks
This avoids allocation of new MonoThreadsSync structures for the typical cases of shallow nesting of uncontended locks. The necessary information (owner, nest and status bits) is embedded in the synchronisation field of a MonoObject. The lock is inflated when the nest overflows or when there is contention on the lock.
This greatly improves performance (over 10 times) for the case of locking a lock only a few times, due to the inflation avoidance. It also improves performance up to 25% for the case of locking a thin lock. A decrease in performance (up to 3 times slower) can happen for the case of repetitive nesting of a lock, due to the need of a CAS at each entry/exit.
libmono now defaults to SGen
libmono library now defaults to using Mono with SGen,
previously, it defaulted to Boehm.
FullAOT: Generic Value Type Sharing improvements
More code is now shared with Value Type sharing and we no longer generate shared wrappers for method signatures as those are not needed.
This release contains a new mode of operation for Mono’s SGen garbage collector as well as many performance optimizations,and memory usage and throughput optimizations
Mono has historically used garbage collectors that can run at any time, that is, when a garbage collection is triggered, the GC system stops all threads preemptively and performs a garbage collection.
This is a behavior that we inherited from Boehm’s GC which was great in the early days of Mono, as it allowed us to get a working garbage collector in no time, but also made the garbage collector harder to debug.
We have introduced a new cooperative configuration to our garbage collector that makes it easier to debug garbage collector related problems and reduces the operating system specific requirements to have a functioning garbage collector.
This mode can be enabled by setting the
Implement Thread Priority Setting
GetPriority facility for real-time threads: if
mono is executed using the
SCHED_RR policy, we will map POSIX priorities
to .NET priorities. Under this policy a thread running under this policy
which uses the
SetPriority API will have its priority remapped and a
pthread_setschedparam() made to change its priority.
For a sample program that shows how to run a Mono application without requiring all root privileges other than the CAP_SYS_NICE capability which enables priority manipulation see the thread-priority page
LLVM Only Mode
It is now possible to use the Mono runtime in LLVM-only mode. This mode avoids the use of any assembly optimized code, or the mixed mode of Mono+LLVM. This is used to generate standard LLVM bitcode.
This comes at the expense of some performance optimizations that are not possible to express with stock LLVM.
We continue to improve the concurrent capabilities of the garbage collector, among those we enabled cementing for it, and tuned various parameters of nursery collection and improved the diagnostic capabilities of the concurrent GC.
We have made the implementation of GC handles lock-free. The previous
implementation would take a lock every time a GC handle was accessed
Removing this locking improves the performance of these operations by
orders of magnitude—particularly on OS X, where locking is costly.
MSBuild Preview for OS X
Command line usage is same as xbuild and supports the same set of command line arguments.
This works with regular .NET projects, Xamarin.Android, Xamarin.iOS,
Xamarin.Forms etc in our limited testing. Bugs for any issues that you run
into can be filed at Bugzilla
using the Component -
Note: This version of msbuild runs into a bug when used with certain F# projects (see Bug #42356). Some build tools like albacore try detecting
xbuild so you may end up inadvertently using msbuild and run into this bug.
64-bit Mono for OS X
We now provide universal (32/64-bit) binaries in our OS X package. 32-bit is still the default Mono executable on the terminal; For 64-bit use
We are now annotating our GC roots, so the profiler can get better visibility into the nature of objects that keep objects alive.
We no longer use the sparse array for the threadpool, as for many thread it would slow down some operations.
The soft debugger now allows nested invocations to take place.
The PowerPC backend has been updated to support big endian systems.
Refactored the Process API (FIXME: Marek, what was the source of this?)
Null operator (?.) has been implemented for dynamic expressions.
The language version
future has been renamed to
We have updated IKVM to support 4GB output files.
Portable Class Libraries
Introduced support for the PCL v3 contracts
Adds support for WatchOS, armv7k and new Android M.
Named events and semaphores
The support for sharing named events/semaphores etc. between processes (MONO_ENABLE_SHM) has been removed. This feature was very complicated to implement on POSIX system and the implementation was very brittle and a constant source of bugs/problems. A possible replacement is to use the similar POSIX functionality in the Mono.Posix assembly.
Major upgrade to Reflection APIs, it implements many features that we never used in the past, but that are required to run Roslyn (FIXME: add more details).
Adds support for
legacy library. Those were added as no-ops
to enable assembling the CoreCLR IL test suite.
Microsoft Source Code Adoption
AuthenticatedStreamclass and family.
FIXME: pull the list
The interactive C# shell now implements code completion by showing a popup on the screen instead of using the Bash-style results.
Code completion is also triggered by the “.” character, which is convenient in many cases, in addition to the existing TAB.
Improved the rendering of Platform enumerations for platforms like iOS where we are interested in when an API was first introduced, not all the platforms that also support it.
Improved the handling of generic methods.
mdoc - New options
-api-style parameter and
-multiassembly parameters can be used
to update documentation in scenarios where we want to maintain a
single XML API, but target slightly different source assemblies (like
we have to do for Xamarin.iOS’s classic and unified, or iOS, tvOS and
multiassembly option lets you run
mdoc update on
assemblies that contain the same types. This can come into play when
you have a set of assemblies that run on different platforms, with a
slightly differing API surface area on each platform (for example:
tvOS, watchOS, iOS); in th`is case you can maintain all of the
documentation in a single set of XML documents.
With this option enabled, an
AssemblyInfo node will be added for
every assembly that a type is found in, in addition to every
member. While this may seem verbose, it’s really the only way to
capture the information about what assemblies a given type or member
can be found in.
Now supports the
--quiet flag to prevent diagnostics messages from being printed out.
xbuild command now defaults to XBuild 14.0 instead of 12.0.
This means .csproj project files that use ToolsVersion=”14.0”
(such as those created by Visual Studio 2015) or that target .NET 4.6
now build without warnings.
Roslyn support: It now copies the Portable PDB files generated by the Roslyn compiler to the output directory.
This new script replaces GNU timeout and is intended to be used by automated builds of Mono on Jenkins or other continuous build systems. In addition, it:
- Logs machine readable output about each test suite (as line-delimited json)
- If the test suite uses NUnit, can detect if a test case failed or crashed (terminated mono in mid-test), and retry unsuccessful tests (up to a limit).
