I'm sorry to say that the Windows tarballs were built without profiling
libraries and will need to be reissued. To prevent confusion I have
removed the bad tarballs until I have a chance to rebuild them.

Cheers,

The Glasgow Haskell Compiler -- version 8.0.2
   ===

The GHC team is happy to at last announce the 8.0.2 release of the
Glasgow Haskell Compiler. Source and binary distributions are available
at

http://downloads.haskell.org/~ghc/8.0.2/

This is the second release of the 8.0 series and fixes nearly
two-hundred bugs. These include,

  * Interface file build determinism (#4012).

  * Compatibility with macOS Sierra and GCC compilers which compile
position-independent executables by default

  * Compatibility with systems which use the gold linker

  * Runtime linker fixes on Windows (see #12797)

  * A compiler bug which resulted in undefined reference errors while
compiling some packages (see #12076)

  * A number of memory consistency bugs in the runtime system

  * A number of efficiency issues in the threaded runtime which manifest
on larger core counts and large numbers of bound threads.

  * A typechecker bug which caused some programs using
-XDefaultSignatures to be incorrectly accepted.

  * More than two-hundred other bugs. See Trac [1] for a complete
listing.

  * #12757, which lead to broken runtime behavior and even crashes in
the presence of primitive strings.

  * #12844, a type inference issue affecting partial type signatures.

  * A bump of the `directory` library, fixing buggy path
canonicalization behavior (#12894). Unfortunately this required a
major version bump in `directory` and minor bumps in several other
libraries.

  * #12912, where use of the `select` system call would lead to runtime
system failures with large numbers of open file handles.

  * #10635, wherein -Wredundant-constraints was included in the -Wall
warning set

A more detailed list of the changes included in this release can be
found in the release notes,

https://downloads.haskell.org/~ghc/8.0.2/docs/html/users_gui
de/8.0.2-notes.html

Please note that this release breaks with our usual tendency to avoid
major version bumps of core libraries in minor GHC releases by including
an upgrade of the `directory` library to 1.3.0.0.

Also note that, due to a rather serious bug (#13100) affecting Windows
noticed late in the release cycle, the Windows binary distributions were
produced using a slightly patched [2] source tree. Users compiling from
source for Windows should be certain to include this patch in their
build.

This release is the result of six months of effort by the GHC
development community. We'd like to thank everyone who has contributed
code, bug reports, and feedback to this release. It's only due to
their efforts that GHC remains a vibrant and exciting project.

Very good Tim!

There are always people more knowledgable than me in #ghc on freenode.

I apologise if it is harder than I anticipated!

Hi Matt,

I noted this down last year as something I wanted to work on for this year.
Just letting you know that I'm starting to look at some of the easier
tickets in that page.

Is there a good person or place to ask questions if I get stuck on anything?

Cheers,

Re: Trac to Phabricator (Maniphest) migration prototype

2017-01-11 Thread Matthew Pickering 
I experimented a bit more with subprojects and I was able to add a +6
line patch to make them behave a bit better.

Specifically, the parent project now appears in the UI and auto
complete works as expected.
