- cleaned up relation slot mixin variants

  1. … 1 more file in changeset.
nx.tcl: - reworked error message generation of slot-forwarder (list all available slot methods with prefix value=)

xotcl2:

- use xotcl::RelationSlot instead of nx::Relationslot in xotcl2

(we can more value=assign here).

  1. … 3 more files in changeset.
nx.tcl: - add slot method value=unset to nx::RelationSlot and nx::VariableSlot - extended regression test

  1. … 3 more files in changeset.
xotcl2: - use value=set instead of value=assign - simplify "-parameter" implementation - add setters for "name", "domain", and "default" to xotcl::Attribute for backward compatibility

  1. … 4 more files in changeset.
nx.tcl, xotcl2.tcl: - use value=* as names for interally called and forwarder-called accessor methods - disallow "assign" for nx::variableSlots

  1. … 12 more files in changeset.
nx.tcl: - use set/get/add as slot methods for get/configure/incremental operations - demangle slots for nx/xotcl2 further

xotcl2:

- use assign/get/add as slot methods for get/configure/incremental

operations

- use object system configuration for -slot.get and -slot.set

  1. … 8 more files in changeset.
- enforce usage of "get" for all slots in nx - TODO: check, what in detail "parameter" in xtocl2 inherit from nx::variableslot (e.g. needsForwarder?)

  1. … 4 more files in changeset.
- enforce using "set" for filter/object-filter in slot operations (same as for mixins)

  1. … 10 more files in changeset.
nx.tcl: - remove setter methods from BootstrapVariableSlots - reducing interface of BootstrapVariableSlots by setting methods protected

  1. … 5 more files in changeset.
nx.tcl: - add "set" as a method name for relation slots - implemented relation slot "mixin" and "object-mixin" via "slotassign" to disallow "/obj/ mixin /value/" and "/obj/ object mixin /value/" to use instead "/obj/ mixin set /value/" and "/obj/ object mixin set /value/" while keeping "configure" and "cget" working. This has the advantage that "/obj/ mixin set" does not try to replace the mixin chain by "set" - adapted regression test - TODO: check, if we need the explicit "slotassign"? isn't the presence of the slotObj sufficient? maybe "-forwardToSlot" in relationSlots? - TODO: demangle "slotassign" in "ObjectParameterSlot protected method getParameterOptions" and check interactions - TODO: to the same as -mixin and -object-mixin to -filter and -object-filter - TODO: clean up relation slot mixin variants - TODO: do we really like the fact that we have to write now "B mixin set M2" instead of "B mixin M2"? - TODO: should we disallow "B mixin" and enforce instead of "B mixin get" ? - TODO: we could as well allow "B mixin clear" instead of "B mixin set {}" - TODO: allow "set" for variable slots as well. Do we need "assign"?

  1. … 14 more files in changeset.
- add flag "-onerror" to nsf::forward::method to handle errors during dispatch of a forwarder (not all error messags of forwarder are already transformed) - added log-level Info which prints always, e.g. for "-verbose" flag of forwarder - drop setter-rule from properties (use always forwarder) - drop "/obj/ /prop/" and "/obj/ /prop/ /value/" in favor of "/obj/ /prop/ get" and "/obj/ /prop/ assign /value/" to achieve better orthogonality with e.g. incremental properties

  1. … 16 more files in changeset.
- replace empty-named arrays by dicts

- preserve lower bound of multiplicity when incemental is added - extend regression test

  1. … 2 more files in changeset.
- added more test cases for multiplicity and incremental

  1. … 2 more files in changeset.
nx.tcl: - Define method "value" as a slot forwarder to allow for calling value-less slot methods like e.g. "get" dispite of the arity-based forward dispatcher. - extend regression test

  1. … 2 more files in changeset.
- update more copyright notices

  1. … 31 more files in changeset.
- use nx rather than xotcl2 terminology in nsf::method::forward

  1. … 8 more files in changeset.
- renamed "-methodprefix" to "-prefix" in nx, since the prefix can be applied as well applied to a cmd.

  1. … 4 more files in changeset.
- use in forwarders "-frame object" instead of "-objframe" in nx for consistency with other calls (e.g. dispatch). Other values for "-frame" are not allowed. (btw, XOTcl has "-objscope")

  1. … 4 more files in changeset.
- library/nx/nx.tcl: Pulling out method contracts (pre- and postconditions) from NX for the time being. Corresponding tests have been commented out or, if applicable, turned into XOTcl2-specific tests.

  1. … 3 more files in changeset.
nsf.c: - fix case, where NsfDStringPrintf() failed (when print llength including \0 was 1 byte longer than print buffer) - make sure, that the list kept for the cached parameter is just built from unshared objects; otherwise Tcl append will abort

nx.tcl:

- new package "nx::volatile"

- don't define configure parameter "-volatile" per default;

use "package req nx::volatile" instead

- don't define per method "volatile" per default;

use "::nsf::method::require ::nx::Object volatile" instead

- get rid of -volatile in nx.tcl and serializer

- update/extend regression test

  1. … 13 more files in changeset.
nsf.c: - let [current methodpath] return full path (similar to -path option in "info methods" - handle collateral damage in regression test due to changed result of "current methodpath"

  1. … 4 more files in changeset.
- raise an error, when an ensemble methods redefined a plain method

  1. … 2 more files in changeset.
- nx.tcl: Throw error exceptions using "return -code error", to exclude the unevaluated error cmd statement from the trace message

  1. … 1 more file in changeset.
nx: - allow copy of objects with required arguments - use ::nsf::object::alloc in "copy" method - don't depend on method "trace", use directdispatch instead - remove method "-noinit" (nsf::object::alloc makes it obsolete) - extend regression test

  1. … 7 more files in changeset.
nsf.c: - new command ::nsf::object::alloc /class/ /obj/ ?/script/? alloc an object and execute script in the context. Can be used to regenerate an object in a old state.

serializer:

- fixed loading of objects with required data in the blueprint

(many thanks for david hopfmueller for reporting this)

- make use of nsf::object::alloc (1 command instead of 1 create + 2 evals)

- these changes imprived laading time of blueprint by about 25%

for OpenACS+xowiki

  1. … 9 more files in changeset.
xotcl2: - fixed "... info defaults ..." and "... info instdefaults ..." emulation in XOTcl 2 - fixed error message - extended regression test - bumped revision of nsf/xotcl/nx to 2.0b6

  1. … 9 more files in changeset.
- nsf: added switch "-checkalways" to nsf::method::create - nx: added switch "checkalways" to "method" and "object method" - extended regression test

  1. … 7 more files in changeset.
monogodb: - updated to most recent version of c-driver (0.7.1) - adapted to nx 2.0b5 (use everywhere cget interface) - tested with mongodb 2.4.5

  1. … 9 more files in changeset.
- prepare for providing nx as a tcl module (.tm file). this is just a preparation, since for testing, one cannot set up a path that prefers a local copy over a global installed one (the global tcl-site is preferred over the one specified in e.g. TCL8_5_TM_PATH)
