[Bordeaux-threads-devel] Fwd: join-thread in allegro

I've forgot to send this to the list. ---------- Forwarded message ---------- From: Kiyoshi Mizumaru <kiyoshi.mizumaru(a)gmail.com> Date: Mon, Mar 26, 2012 at 1:02 PM Subject: Re: [Bordeaux-threads-devel] join-thread in allegro To: Stelian Ionescu <sionescu(a)cddr.org> I think it's good idea to solve this without defining a new process class. But in b03b582, make-lock, with-lock-held and current-thread are used prior to be defined, and lead to compile error. Moving the "Thread creation" section solved this and works as expected: https://bitbucket.org/kmizumar/bordeaux-threads/changeset/02cc8c9b4ce7 Kiyoshi -- Kiyoshi Mizumaru <kiyoshi.mizumaru(a)gmail.com> On Mon, Mar 26, 2012 at 8:24 AM, Stelian Ionescu <sionescu(a)cddr.org> wrote: > On Mon, 2012-03-26 at 00:35 +0900, Kiyoshi Mizumaru wrote: >> Hi, >> >> Even though the api documentation doesn't mention it, I've found that >> join-thread is expected to have a value of the thread's function in some >> lisp implementations. >> >> (asdf:test-system :sqlite) always fails in concurrent access test since >> it checks return values of join-thread and join-thread's value is nil in >> current implementation for Allegro CL.

[Bordeaux-threads-devel] join-thread in allegro
by Kiyoshi Mizumaru 25 Mar '12

25 Mar '12

Hi, Even though the api documentation doesn't mention it, I've found that join-thread is expected to have a value of the thread's function in some lisp implementations. (asdf:test-system :sqlite) always fails in concurrent access test since it checks return values of join-thread and join-thread's value is nil in current implementation for Allegro CL. The followings are changes I've made to correct this problem, so please have a look at it. https://bitbucket.org/kmizumar/bordeaux-threads/changeset/5de529f36b92 https://bitbucket.org/kmizumar/bordeaux-threads/changeset/549bbcdcf794 Thanks in advance and sorry for my poor English, I'm still learning it.

[Bordeaux-threads-devel] test suite crashes CMUCL
by Anton Vodonosov 05 Mar '12

05 Mar '12

BTW, another tests issue I forgot to report: On CMUCL bordeaux-threads test suite traps into some active deadlock, produces 8 MB of '.' symbols in log, constantly runs GC and finally dies when heap is exhausted. Best regards, - Anton

[Bordeaux-threads-devel] test failures
by Anton Vodonosov 29 Feb '12

29 Feb '12

Hello. In the scope of this project https://github.com/cl-test-grid/cl-test-grid I and Robert Goldman run tests of CL libraries on various CL implementations. Bordeaux threads tests fails on some implementations, sometimes due to buts in the tests I suppose. You may find reports here http://common-lisp.net/project/cl-test-grid/ Probably the most convenient report to overview a single library status is this one: http://common-lisp.net/project/cl-test-grid/pivot_lib-lisp_ql.html Between the test results for the recent version of quicklisp and the previous one, bordeaux-threads has only one regression: sbcl-1.0.54.45-a2bef14-macosx-x64. Probably it's due to some bug (like race conditions) in the tests, because the Qicklisp Blog doesn't list bordeaux-threads between updated projects in the last distro update, and if it's true, than the results are from the same bordeaux-threads version. http://blog.quicklisp.org/2012/02/february-dist-update-now-available.html Best regards, - Anton

There's a new release of Bordeaux-Threads. Noteworthy changes since 0.8.0: * Update ABCL support, reimplementing locks based on java.util.concurrent.locks.ReentrantLock and adding condition variables - thanks to Mark Evenson * Remove warning about threads not being supported, when applicable -- Stelian Ionescu a.k.a. fe[nl]ix Quidquid latine dictum sit, altum videtur. http://common-lisp.net/project/iolib

[Bordeaux-threads-devel] [Updated]Patch for ABCL against BORDEAUX-THREADS HEAD
by Mark Evenson 07 Apr '11

07 Apr '11

Please consider the [following patch for ABCL against BORDEAUX-THREAD HEAD][1]. The patch provides implementation of both BT locking semantics (recursively head and not) by use of [java.util.concurrent.locks ReentrantLock][2] as well as a (hopefully) correct implementation of POSIX-style condition variable, and allows non-blocking lock acquisition. [1]: http://slack.net/~evenson/abcl/hunchentoot/bordeaux-threads-abcl-20110215a.… [2]; http://download.oracle.com/javase/6/docs/api/java/util/concurrent/locks/Ree… -- "A screaming comes across the sky. It has happened before, but there is nothing to compare to it now."

[Bordeaux-threads-devel] binding output stream in thread for slime use
by Antony 30 Dec '10

30 Dec '10

Hi I am trying to use bordeaux threads. Trying to figure out how to make output from a thread function appear in slime instead of the lisp terminal. The lisp I am using is Clozure Common Lisp Version 1.6-r14468M (WindowsX8664) I beleive I have the latest bordeaux threads Following is my test code. I hope the intentions are clear. What am I doing wrong or missing? Code follows Thanks, -Antony (asdf:oos 'asdf:load-op :bordeaux-threads) (format t "~%appearing in slime") (defun thread-test () (format t "~%appearing in lisp terminal: ~A" (bordeaux-threads:thread-name (bordeaux-threads:current-thread)))) (let ((bindings '((*standard-input* . *standard-input*) (*standard-output* . *standard-output*) (*query-io* . *query-io*) (*trace-output* . *trace-output*)))) ;;is this correct? (dolist (name '("foo" "bar")) (bordeaux-threads:make-thread #'thread-test :name name :initial-bindings bindings)))

[Bordeaux-threads-devel] patch for thread-wait
by Faré 14 Dec '10

14 Dec '10

Dear bordeaux-threads developers, I have a patch that adds bt support for thread-wait and thread-wait-with-timeout, modelled after the process-wait and process-wait-with-timeout functions sported by several Lisp APIs. This API should be considered a legacy compatibility API, as these operations may have made sense long ago on timesharing monoprocessors, but are necessarily expensive on multiprocessors. Nevertheless, we had a use for them at ITA, and I threw together this compatibility support, until we get our code cleaned up. Please consider this patch for inclusion, though it has only been lightly tested. PS: I also have a patch to add XCVB support to bordeaux-threads, though you might not be interested.

[Bordeaux-threads-devel] Patch for ABCL against BORDEAUX-THREADS-0.8.0
by Mark Evenson 04 Dec '10

04 Dec '10

ABCL's multithreading symbols have moved to THREADS package (this was deprecated with abcl-0.18 and removed with abcl-0.22). Implement CONDITION-WAIT and CONDITION-NOTIFY for ABCL. Use 10ms pause for ABCL's THREAD-YIELD. -- "A screaming comes across the sky. It has happened before, but there is nothing to compare to it now."
