There are problems with this fix, e.g. <https://bugs.gnu.org/32367>. More generally, nearly arbitrary code can be run in the top-level expressions of a module. It could launch other threads which try to load modules, or even send messages to other existing threads asking them to do work. In some cases, the body of the module might never terminate. The entire main program might be run from there. I suspect that's not unusual. I can see another problem as well: while the module is in the process of loading, the partially-loaded module is globally visible and accessible to other threads. If I'm not mistaken, with this patch, there's nothing preventing other threads from attempting to use the partially-loaded module. I thought about how to fix this thread-safety problem a long time ago, and came up with a rough outline of a solution. The idea is that the module should not be added to the global module table until the module has finished loading. While the module is being loaded, it would be made visible only to the loading thread, and to any other threads spawned during the loading process, by adding the module to a local list of modules-being-loaded referenced by a fluid variable. If any other threads attempt to access the module, it would not be found in the global module table, and thus trigger an auto-load, which would wait for the lock to be released before proceeding. What do you think? Mark

I forgot to mention an important aspect of the proposed auto-load locking here. It would not be a global lock, but rather a lock specific to the module being loaded. So, I guess we would need a global table of locks for modules-being-loaded. Since Guile (unfortunately) allows cyclic module dependencies, we would need a mechanism to avoid deadlocks in case modules A and B both import each other, and two threads concurrently attempt to load those modules. The first idea that comes to mind is to also have a global structure storing a partial order on the modules currently being loaded. If, while module A is being loaded, there's an attempt to auto-load module B, then an entry (A < B) would added to the partial order. The partial order would not allow cycles to be introduced, reporting an error in that case. In case a cycle would be introduced when adding (A < B), then the thread would simply be given access to the partially-loaded module B, by adding B to its local list of modules-being-loaded. Comments and suggestions welcome, Mark

Item (2) above is something that I had already envisioned in my proposal, although I neglected to mention it. However, I don't see how recursive mutexes would help here, or how they could obviate the need for the other mechanisms I described above. Suppose module A and module B are mutually dependent on each other. If thread 1 is loading module A concurrently with thread 2 loading module B, then thread 1 will be the only thread with access to module A (via thread 1's local list) and will hold the lock on it, and similarly for thread 2 and module B. Now, when thread 1 tries to load module B (while it's in the process of loading module A), it should normally be blocked until module B is finished loading. If those modules were _not_ mutually dependent on each other, we should insist on thread 1 waiting for module B to finish loading before gaining access to it. Only if there is a cyclic dependency should it be granted access to the partially-loaded module. If we simply use recursive mutexes, I think deadlock would occur in this case. Thread 1 would try to grab the lock on module B, which is already held by thread 2, and vice versa. Since it's not self-held, I fail to see the relevance of the recursive mutex. What do you think?

(%force-lazy-module-cell!, %module-waiting-for?) (%module-waiting-for!): New procedures. (resolve-module): If the requested module is not in the regular global module table, look in '%local-modules-being-loaded' and '%modules-being-loaded', and handle these cases appropriately. Support looping without recursively locking the autoload lock. When autoloading, unlock the mutex before calling 'try-load-module'. (try-module-autoload): Add entries to '%modules-being-loaded' and '%local-modules-being-loaded' before loading the module. Also, load the module with the autoload mutex unlocked. When the load attempt finishes (or fails), add the module to the regular global module table if it was ever created, signal the threads waiting for this module, and remove it from the '*-begin-loaded' and '%modules-waiting-for' tables. (call-with-module-autoload-lock): Accept a unary procedure instead of a thunk. (module-name): Adapt to the new 'call-with-module-autoload-lock'. (nested-define-module!): If we're asked to define a submodule of a module that's currently being loaded, install the parent module being loaded into the global module table. * module/ice-9/threads.scm (call-with-module-autoload-lock): Pass the mutex as an argument to the procedure. * test-suite/tests/threads.test: Add tests. * test-suite/tests/delayed-test.scm, test-suite/tests/mutual-delayed-a.scm, test-suite/tests/mutual-delayed-b.scm, test-suite/tests/mutual-delayed-c.scm: New files. * test-suite/Makefile.am (EXTRA_DIST): Add them. --- module/ice-9/boot-9.scm | 292 ++++++++++++++++++++++---- module/ice-9/threads.scm | 4 +- test-suite/Makefile.am | 7 +- test-suite/tests/delayed-test.scm | 28 +++ test-suite/tests/mutual-delayed-a.scm | 29 +++ test-suite/tests/mutual-delayed-b.scm | 29 +++ test-suite/tests/mutual-delayed-c.scm | 29 +++ test-suite/tests/threads.test | 66 +++++- 8 files changed, 435 insertions(+), 49 deletions(-) create mode 100644 test-suite/tests/delayed-test.scm create mode 100644 test-suite/tests/mutual-delayed-a.scm create mode 100644 test-suite/tests/mutual-delayed-b.scm create mode 100644 test-suite/tests/mutual-delayed-c.scm diff --git a/module/ice-9/boot-9.scm b/module/ice-9/boot-9.scm index d8801dada..404a19d49 100644 --- a/module/ice-9/boot-9.scm +++ b/module/ice-9/boot-9.scm @@ -2502,13 +2502,32 @@ interfaces are added to the inports list."

Great, thanks a lot! On a cursory look, it LGTM. I wonder if we could somehow split =E2=80=98resolve-module=E2=80=99 and =E2=80=98try-module-autoload=E2=80=99 = into smaller chunks because they=E2=80=99ve become quite large and complex. For example: > + (lambda () > + (when mutex > + ((ice-9-threads 'lock-mutex) mutex)) > + (set-autoloaded! dir-hint name didit))) > + > + ;; If the local module was actually created, then we > + ;; now add it to the global module table. > + (let ((module (car lazy-module-cell))) > + (when module > + (module-define-submodule! parent-module > + (car reverse-name) > + module))) > + > + ;; Signal all threads waiting on the condition variable > + ;; for this module to be loaded. > + (when cond-var > + ((ice-9-threads 'broadcast-condition-variable) cond-var)) > + > + ;; Remove the module from '%modules-being-loaded'. > + (set! %modules-being-loaded > + (assoc-remove! %modules-being-loaded > + module-name)) > + > + ;; Remove all '%modules-waiting-for' entries that are > + ;; directly related to the module that we just loaded > + ;; (or attempted to load). > + (set! %modules-waiting-for > + (filter! (lambda (entry) > + (not (or (equal? module-name (car entry)) > + (equal? module-name (cdr entry))= ))) > + %modules-waiting-for)) Perhaps this bit could go in a =E2=80=98record-module-autoload-completion!= =E2=80=99 procedure or something along these lines? It=E2=80=99s great that you came up with tests to reproduce the problems. I confirm that =E2=80=9C./check-guile threads.test=E2=80=9D works for me. Th= e tests pass even if I remove the {boot-9,threads}.scm changes, though.
