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"?

- 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

- 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

- 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")

- 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.

build-process: - replace make.tcl by the much simpler mkIndex.tcl: * Does not use pkg_mkIndex * Does not load binary files (problem for cross compiling) * Requires package provide with constant in one line.

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

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

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

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

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)

  1. … 3 more files in changeset.
- explore the usage of dict instead of anonymous array

- use tcl8.5 commands instead of 8.4 idioms

  1. … 5 more files in changeset.
- further release work

nsf.c - removed obsolete function AssertionAppendPrePost() - removed obsolete function NsfNSCopyCmdsCmd() and ::nsf::nscopycmd (handled now more general on scripting level in the "copy" method)

nx.tcl:

- "copy" method: fixed copying of class-level per-object methods

- extended regression tests

  1. … 5 more files in changeset.
nsf.c - fixed a bug in "info methods returns" in cases, where no returns info was available. - we can "/obj/ copy" now objects/classes containing * aliases * setter * ensemble methods * method protections Instead of handling cmd copying in NsfNSCopyCmdsCmd, it is replaced now by introspection. - extended regression test

  1. … 5 more files in changeset.
- changed multiplicity of mixin, object-mixin, filter, object-filter from 1..n to 0..n; rationale: when one has a list of eg. mixins, which should be passed, one has to test for the length before passing it, otherwise the empty list would generate an error. Allowing 0..n makes the usage simpler and the program shorter.

nx.tcl: - renamed variable option "-config" to "-configurable" to make its intention clearer
