2007-05-05 Ludovic Courtès <ludo@chbouib.org>
|
||||
|
||||
Implemented lazy duplicate binding handling. Fixed the
|
||||
`module-observe-weak' API.
|
||||
|
||||
* boot-9.scm: Updated the `module-type' documentation under "{Low
|
||||
Level Modules}".
|
||||
(module-type)[import-obarray]: New slot.
|
||||
[duplicates-interface, observer-id]: Removed.
|
||||
(make-module): Updated accordingly. Use a weak-key hash table for
|
||||
weak observers, so that observers aren't unregistered when the
|
||||
observing closure gets GC'd.
|
||||
(module-duplicates-interface, set-module-duplicates-interface!,
|
||||
module-observer-id, set-module-observer-id!): Removed.
|
||||
(module-import-obarray): New.
|
||||
(module-observe-weak): Accept a new OBSERVER-ID argument allowing
|
||||
callers control over when the observer will get unregistered.
|
||||
(module-call-observers): Use `hash-for-each' rather than
|
||||
`hash-fold'.
|
||||
(module-local-variable, module-variable): Removed, now implemented
|
||||
in C.
|
||||
(module-make-local-var!): Simplified. No need to check for the
|
||||
value of a same-named imported binding since the newly created
|
||||
variable is systematically assigned afterwards.
|
||||
(module-use!): Check whether MODULE and INTERFACE are `eq?'.
|
||||
(module-use-interfaces!): Simplified. No longer calls
|
||||
`process-duplicates'.
|
||||
(beautify-user-module!): Use `module-use!' rather than
|
||||
`set-module-uses!' when importing THE-SCM-MODULE.
|
||||
(process-define-module): Added an AUTOLOADS local variable so that
|
||||
autoloads are handled separately from regular interfaces.
|
||||
(make-autoload-interface): Updated `module-constructor'
|
||||
invocation.
|
||||
(module-autoload!): New.
|
||||
(make-duplicates-interface, process-duplicates): Removed.
|
||||
(top-repl): Use `module-autoload!' rather than
|
||||
`make-autoload-interface'.
|
||||
|
||||
2007-02-18 Neil Jerram <neil@ossau.uklinux.net>
|
||||
|
||||
* gds-client.scm (connect-to-gds): Break generation of client name
