Re: HEADS UP: running tests in /tmp and the `extra_files` setup function

2016-05-17 Thread Thomas Miedema 
Is there a way to change where the temporary directory is made?


There is not.

But it shouldn't be necessary, since during a complete test run, (most)
generated files are deleted after each individual test has finished.

This behavior recently changed (#9758), see my previous email about this:

Hello Thomas,

Is there a way to change where the temporary directory is made?  The
test suite can take a lot of disk space and some of us would prefer
to store the test output on a different partition.

Thanks,
Edward

Hmm, it looks like the new paths rather clutter the testsuite summary
produced at the end of the run,


   /tmp/ghctest/jvZ6KB/1/2/3/./indexed-types/should_fail/T3330a  T3330a [stderr 
mismatch] (normal)
   /tmp/ghctest/jvZ6KB/1/2/3/./indexed-types/should_fail/T4174   T4174 [stderr

   /tmp/ghctest/jvZ6KB/1/2/3/./indexed-types/should_fail/T4179   T4179 [stderr

Perhaps we should strip off the root path from the test names?

Cheers,

Re: 8.0.1 source tarballs available (yet again)

2016-05-17 Thread Ben Gamari 
tl;dr: We are giving this release yet another attempt. Cross your
   fingers and try building again.

So after many attempts I was able to reproduce the issue seen by 
Andrés and Karel and believe I have merged a fix. The issue is
documented as Trac #12078. Thanks to everyone who helped pin down
the issue.

I've uploaded a new set of source tarballs to the usual location,

http://downloads.haskell.org/~ghc/8.0.1/

These tarballs are derived from,

4986837f8168cacf95c24fecc84d7b36c47f3c11

For reference, the SHA1 sum of the new source tarballs is,

585a2d34a17ce2452273147f2e3cef1a2efe1aa5  ./ghc-8.0.1-src.tar.xz

Let me know how your builds go. I don't anticipate any further issues,
but one rarely does.

Finally: thank you all so much for your patience while we worked through
these issues. I hope it's a long time until we see such a drawn out and
problematic release.

Cheers,

- Ben

HEADS UP: running tests in /tmp and the `extra_files` setup function

2016-05-17 Thread Thomas Miedema 
Hello GHC developers,

the testsuite driver now runs each test in a temporary directory in /tmp,
after first linking/copying all files that the test requires to that
directory.

When adding a new test:

** if your test requires source files that don't start with the name of
your test, then you *have to* specify those files using the `extra_files`
setup function. [1]*

* you no longer have to specify files to cleanup (`clean_files` and
`clean_cmd` are deprecated)

* you no longer have to add generated files to `testsuite/.gitignore`

* you no longer have to worry about two tests possibly overwriting each
others intermediate (.o, .hi) files, and you no longer have to
specify `-outputdir` if you want to let multiple tests use the same source
files.

Example:

*BEFORE:*
test('driver011',
 extra_clean(['A011.hi', 'A011.o']),
 run_command,
 ['$MAKE -s --no-print-directory test011'])

*AFTER:*
test('driver011',
 extra_files(['A011.hs']),
 run_command,
 ['$MAKE -s --no-print-directory test011'])

See https://ghc.haskell.org/trac/ghc/ticket/11980 and
https://ghc.haskell.org/trac/ghc/wiki/Building/RunningTests/Adding for more
information.

Cheers,
Thomas

[1] Extra files for existing tests are currently listed in
`testsuite/driver/extra_files.py`.

Hello GHC packagers,

Thanks for your help in the last few days working through what were
hopefully the last issues in the release. I've uploaded a new set of
source tarballs at,

 http://downloads.haskell.org/~ghc/8.0.1/


I got the following error (on Linux):

make[1]: *** [utils/ghc-pkg/dist/build/tmp/ghc-pkg] Error 1


That's exactly the issue which should be fixed in this round. Ben cited 
this as an issue affecting Solaris and FreeBSD and you are lucky to be 
able to duplicate this on Linux.


Anyway, please verify that your -src.tar.xz does have following sha256 sum:

b677e215cdfa22fba534b9bf7b530a056113c1f01002eae5b576e92ced9193ba

I guess you are using older sources from previous round as website is 
notoriously known for excessive caching...

I got the following error (on Linux):

$ make
/usr/bin/ld: cannot find -lHSghc-boot-th-8.0.1
collect2: ld returned 1 exit status
make[1]: *** [utils/ghc-pkg/dist/build/tmp/ghc-pkg] Error 1


I had no this problem with the previous source tarballs.

Best,

8.0.1 source tarballs available (yet again)

2016-05-17 Thread Ben Gamari 
tl;dr: We are giving this release another attempt. Cross your fingers
   and try building again.

Hello GHC packagers,

Thanks for your help in the last few days working through what were
hopefully the last issues in the release. I've uploaded a new set of
source tarballs at,

http://downloads.haskell.org/~ghc/8.0.1/

These tarballs are derived from,

787900138b94790ddd13d76c2853d789d3335a5d

This commit differs from the previous tarball in a number of ways,

 * a variety of packaging issues surrounding haddock's documentation
   have been fixed

 * the ghc-boot library has been split up. It was pointed out quite late
   that the previous structure of ghc-boot greatly increased the
   dependency footprint of the template-haskell package, which would
   have made it nearly impossible to upgrade the bytestring and binary
   packages.

 * a pair of fixes for crashes on PowerPC have been merged

 * a patch addressing a serious performance issue in parallel garbage
   collection has been merged

 * the bytestring module has been bumped to 0.8.10.1, fixing a rather
   serious correctness issue on big-endian systems

We'll have the usual one-week build window for binary distributions.
As always, let either Austin or I know if you have any trouble building
your distribution. I have yet to push the ghc-8.0.1 tag in case we
encounter unexpected issues but all of my builds with this tarball
thusfar have gone quite well (then again, so did those of the previous
tarball).

Good luck and thanks for all of your work!

Cheers,

- Ben

This is quite useful! Thanks for writing it down. A few points:

It might be nice if it defined HPT and EPS a bit more concretely (at
least expand the acronyms, ideally including a bit of text defining
their roles in the compiler and why there is two of them).

You say "we produce TyCons and another type checking entities for them".
Should this read "other type checking entities for them"?

Otherwise it looks good to me.

Cheers,

- Ben

New wiki page about tying the knot in GHC

2016-05-17 Thread Edward Z. Yang 
Hello all,

I've written a new wiki page about how knot tying works in
GHC:

https://ghc.haskell.org/trac/ghc/wiki/Commentary/Compiler/TyingTheKnot

Please let me know if anything is unclear and I'll try to
revise it for more clarity.

Edward
