Added check in TclObject::create_framevar() so that it will do

the variable does not exist, the 'set var 0' won't change the

yet. However, if it's already there (e.g., we have two
instvars of the same variable in the same frame), this 'set

Better support for delayed binding (nee classinstvars);
added some length checking to buffers.
<p>
Delayed binding is <strong>only</strong> available
if you configured tclcl and otcl with the option
<strong>--enable-tclcl-classinstvar</strong>.
(When doing so, btw, make sure you've got everyone built
the same way, or you'll get random crashes due to
mismatched slots in virtual function tables.)
<p>
Delayed binding are a way to do binding between OTcl and C++
that consume memory only when bound variables are actually
in use from Tcl.
(Normally bound variables consume memory throughout the lifetime
of the object.)
Delayed binding is therfore useful if you have
an object with many instances (for example, an NsObject)
whose bound variables are only occationaly used from Tcl
(for example, off_cmn_).
<p>
Here's a minimal example of delayed binding:
<pre>
class C5 : public TclObject {
public:
C5();
virtual int delay_bind_dispatch(const char *varName, const char *localName);
virtual void delay_bind_init_all();
protected:
int normal_;
int delayed_;
};
DEFINE_OTCL_CLASS(C5, "C5")
{
}
C5::C5()
{
bind("normal_", &normal_);
}
void
C5::delay_bind_init_all()
{
delay_bind_init_one("delayed_");
}
C5::delay_bind_dispatch(const char *varName, const char *localName)
{
DELAY_BIND_DISPATCH(varName, localName, "delayed_", delay_bind, &delayed_);
return TclObject::delay_bind_dispatch(varName, localName);
}
</pre>
<p>
From Tcl there should be no visible differences between
delayed and normally bound variables.
<p>
The penality for delayed binding is higher run-time cost.
Classes with delayed binding incur a search cost proprotional
to class hierarchy depth (of that class) and the number of delay-bound
variables in that class hierarchy.
<p>
(What happens with delayed binding
is that you call the delay_bind_dispatch function
for each instvar/set/get, this function percolates up the class
hierarchy. (This is basically how command dispatch currently works.)
With normal binding each instvar is put in a Tcl_Hash
and accessed in O(1) time (but with higher memory requirements).
<p>
For a simple ns run with ~1400 NsObjects (~120 nodes/links/agents)
and both of NsObject's
variables delay-bound run-time went up ~2% (not clear if this is outside
expected error) and memory went down 10%.
For larger simulations run-time cost should stay constant
memory savings should rise.
(If you want to your own benchmarks,
my test case was
./ns tcl/ex/many_tcp.tcl -client-arrival-rate 20 -ns-random-seed 1 -mem-trace 1.)

<ul>
<li> In Makefile.in, a set of tcl library files are currently packaged
with a set of tk library files in the embedded tcl object, et_tk. To
include these tcl library files (but not the tk library files) in the
smash executable (a.k.a. mash w/out tk), I would like to package them in
a separate embedded tcl object, et_tcl. For now, just added et_tcl, but
after get ns-developers approval, will remove tcl library files from
et_tk. Btw, also added new embedded tcl files, tcl-import.tcl and
tcl-http.tcl, to et_tcl.
<li> Added ability for mash interpreter to import objects from the web
server, as opposed to just local file-server (by specifying the
TCLCL_IMPORT_DIRS environment variable).
<li> Augmenting mash interpreter's "source" procedure to accept EITHER a

<li> Augmenting the mash interpreter's "import" procedure to accept

<li> Added a section for "Proc Methods" on the API page for each Object for which procs are defined.
<li> Added a page, linked from index.html, that lists all of the procs not associated with a particular Object.
<li> Fixed "is_tcl_comment" proc to consider lines that start with '#', even if preceeded by whitespace, to be considered comments.
<li> Since omitting classes from the class hierarchy could be misleading, now all the subclasses of a class are expanded at every place they occur, thus making the class hierarchy on index.html more accurate. To do this, simply commented out "set mark($c) 1" which was used to prevent a subclass from being outputted to index.html if it had already been outputted earlier on the page.
<li> Timestamped all pages outputted.
<li> Class definitions are processed w/out restricting their length to a single line.

<ul>
<li> Added support for a simple, java-like import command

By default, import directives are ignored so as to not
break existing apps. "import" behaves like the tcl source command
except it includes the file only once (even when used multiple
times) and the OTcl class name is specified instead
of the actual file. To facilitate this, import assumes the
existence of a file called importTable that contains the
mappings (... maybe this should be built on demand).
mash-1/mkImportTable creates this table from a list
of tcl input files (should move this to tclcl).

Wed Dec 17 20:10:01 PST 1997
</b>
<ul>
<li> Made a bunch of changes to otcldoc to handle C++ method
and class documentation. This is less automatic than the OTcl
counterpart because it's harder to scan the input file.
Thus, we sort of give up and rely upon structured comments.
The model is to indicate a class or method def with the tag "<otcl>"
prepended to the equivalent syntax (within a C comment).
Then the comment block following this line becomes the
html desription. E.g.,
<pre>
/*
* <otcl> Class Foo -superclass Bar
* Foo is the base class for all foo-like objects blah blah.
*
* <otcl> Foo public run {}
* The run method causes a foo object to start running.

<ul>
<li> Moved the call to TclObject::init from the tclcl-mappings
macro into the TclClass object creator. The previous arrangement
caused init to be called before TclObject::name_ was set, preventing
the init method from calling the Otcl object (although it could
get the name out of argv[0], the object was not in the hash table
so TclObject::lookup wouldn't work for it). Since TclObject::init
is now always called, I changed it to always return TCL_OK
(typically the args are passed up to Object anyway).

<ul>
<li> Still trying to get constructor argument passing write.
Removed an eval because catch does effectively the same thing
(i.e., expands args so that it is properly interpreted as multiple

null arguments (e.g., "") where present.

<b>
Fri Aug 29 23:57:41 PDT 1997
</b>
<ul>
<li> Changed reaction to the failure of the shadow object creation.
Rather than raise a tcl error, the OTcl object is deleted and "new"
returns an empty string. This allows the callee to react to a
failed "new" call. If the problem is in the OTcl constructor rather
than in the actual creation of the C++ shadow, the error is
raised as before.

Return TCL_ERROR if TclClass constructor fails

<ul>
<li> Changed TclObject::unknown to invoke Tcl "error" procedure upon
encountering an undefined method. Previously, this condition caused
the process to exit, often making debugging difficult.
Under Tk, "error" raises a pop-up that allows one to dump
the call stack, which typically makes debugging much easier.

Changes to make libTcl compile under windows and prepare for transition of the
package to tclcl, pronounced Tickle-C-L. It stands for "Tcl Class". Motivation
for the change: (1) hard to difference between Tcl and tcl verbally, (2) more
importantly, under an OS with case-insensitive filenames like win32, "tcl.h"
conflicts with "Tcl.h".
<ul>
<li> moved contents of Tcl.h to tclcl.h. Please make all future changes to
tclcl.h. Old "Tcl.h" is retained but it only includes "tclcl.h". Eventually
we should get rid of "Tcl.h" completely. All includes in the package has
been updated to use "tclcl.h".
<li> added compat/gettod.c for gettimeofday function in win32
<li> added tclcl-config.h for conditional defines in win32
<li> added makefile.vc for windows. do 'nmake -f makefile.vc' to compile to
tclcl.lib under windows. (we should change libTcl.* to libtclcl.* in
Makefile.in some time later).
</ul>
<li><b><a href="http://www.cs.berkeley.edu/~yatin">[YC]</a></b>
<b>Tue Aug 5 09:49:56 PDT 1997</b><br>
Added macros to the Tcl library to allow automatic definitions of the mappings
between TclObjects and OTcl classes
<ul>
<li> The OTCL_MAPPINGS macro defines the mapping between a TclObject class
and a corresponding OTcl class. With this definition, the manner in which
arguments are passed to the constructor for the object has changed. Instead
of parsing the args in subclass_of_TclClass::create, the object is now
created with an empty constructor (i.e. subclass_of_TclObject() ). Once the
object has been successfully constructed, a new virtual method init(argc,
argv) is invoked on that object. The argv array contains some dummy args
for argv[0] and argv[1] (whatever were originally passed to some of the
elements of argv for the TclClass::create method). The actual args start at
argv[2]. Note that this is different from what used to happen for the create
method. I made this change so that the structure of the argv array is
consistent with the structure that is passed to the command(argc, argv)
method. (Please note that this does *not* break any previous code that used
the original TclClass's create mechanism to create TclObjects.)
<li> INSTPROC defines a mapping between a C++ method and an OTcl method.
This mechanism is cleaner than the original single huge command() method. It
ensures that all C++ methods are visible thru "$object info instcommands",
and allows "$self next" to work even for these C++ methods! Use the argument
parsing functions described below to parse out the argv array into individual
arguments
<li> BEGIN_PARSE_ARGS(argc, argv): start parsing the arguments array
<li> ARG(var): parse the next argument into the variable 'var'. Currently,
the type of 'var' can be one of int, unsigned int, double, const char *,
TclObject *.
<li> ARG_DEFAULT(var, default): same as ARG, except you can specify a
default value to use if this arg has not been specified in the cmdline
<li> END_PARSE_ARGS: clean up at the end of parsing. Check for extra
arguments that might have been passed in, and output an error if there are
any. Even if your function does not expect any arguments, use
BEGIN_PARSE_ARGS and END_PARSE_ARGS at the start of your function to ensure
that you check for any spurious args that have been passed into this function
<li> Example:
<pre>
class TestClass : public TclObject {
public:
TestClass(); /* must have this constructor */
virtual int init(int argc, const char * const *argv) {
int myarg;
BEGIN_PARSE_ARGS(argc, argv);
ARG(my_arg);
END_PARSE_ARGS;
/* ... use 'myarg' in the initialization of this object */
}
int func1(int argc, const char * const *argv) {
char *name;
BEGIN_PARSE_ARGS(argc, argv);
ARG(name);
END_PARSE_ARGS;
// ...
}
int func2(int argc, const char * const *argv) {
BEGIN_PARSE_ARGS(argc, argv);
END_PARSE_ARGS;
// ....
}
}
OTCL_MAPPINGS(TestClass, "TestClass") {
INSTPROC(func1, "func1");
INSTPROC(func2, "func2");
}
