Tcl Source Code

A NOTE ON THE CHANGELOG:
Starting in early 2011, Tcl source code has been under the management of
fossil, hosted at http://core.tcl.tk/tcl/ .  Fossil presents a "Timeline"
view of changes made that is superior in every way to a hand edited log file.
Because of this, many Tcl developers are now out of the habit of maintaining
this log file.  You may still find useful things in it, but the Timeline is
a better first place to look now.

	* doc/next.n (METHOD SEARCH ORDER): Bug [3606943]: Corrected
	description of method search order.

2013-09-18  Donal Fellows  <[email protected]>

	Bump TclOO version to 1.0.1 for release.

2013-09-17  Donal Fellows  <dkf@users.sf.net>

	* generic/tclBinary.c (BinaryEncodeUu, BinaryDecodeUu): [Bug 2152292]:
	Corrected implementation of the core of uuencode handling so that the
	line length processing is correctly applied.
	***POTENTIAL INCOMPATIBILITY***
	Existing code that was using the old versions and working around the
	limitations will now need to do far less. The -maxlen option now has

	* unix/tcl.m4:  Bug [32afa6e256]: dirent64 check is incorrect in tcl.m4
	* unix/configure: (thanks to Brian Griffin)

2013-06-27  Jan Nijtmans  <[email protected]>

	* generic/tclConfig.c: Bug [9b2e636361]: Tcl_CreateInterp() needs
	* generic/tclMain.c:   initialized encodings.

	command with expansion ([list {*}blah]) into bytecode that does not
	call an external command.

2013-05-06  Jan Nijtmans  <[email protected]>

	* generic/tclStubInit.c: Add support for Cygwin64, which has a 64-bit
	* generic/tclDecls.h: "long" type. Binary compatibility with win64
	requires that all stub entries use 32-bit long's, therefore the need
	for various wrapper functions/macros. For Tcl 9 a better solution is
	needed, but that cannot be done without introducing binary
	incompatibility.

2013-04-30  Andreas Kupries  <[email protected]>

	* library/platform/platform.tcl (::platform::LibcVersion):
	* library/platform/pkgIndex.tcl: Followup to the 2013-01-30 change.
	The RE become too restrictive again. SuSe added a timestamp after the
	version. Loosened up a bit. Bumped package to version 1.0.12.

2013-04-29  Donal K. Fellows  <[email protected]>

	* generic/tclCompCmds.c (TclCompileArraySetCmd): Generate better code
	when the list of things to set is a literal.

2013-04-25  Jan Nijtmans  <[email protected]>

	* generic/tclDecls.h: Implement Tcl_NewBooleanObj, Tcl_DbNewBooleanObj
	and Tcl_SetBooleanObj as macros using Tcl_NewIntObj, Tcl_DbNewLongObj
	and Tcl_SetIntObj. Starting with Tcl 8.5, this is exactly the same, it
	only eliminates code duplication.
	* generic/tclInt.h: Eliminate use of NO_WIDE_TYPE everywhere: It's
	exactly the same as TCL_WIDE_INT_IS_LONG

2013-04-19  Jan Nijtmans  <[email protected]>

	* generic/tclDecls.h: Implement many Tcl_*Var* functions and
	Tcl_GetIndexFromObj as (faster/stack-saving) macros around resp their

.IP [5]
The method chain is cached for future use.
.SS "METHOD SEARCH ORDER"
.PP
When constructing the method chain, method implementations are searched for in
the following order:
.IP [1]


In the classes mixed into the object, in class traversal order. The list of
mixins is checked in natural order.
.IP [2]
In the classes mixed into the classes of the object, with sources of mixing in
being searched in class traversal order. Within each class, the list of mixins
is processed in natural order.
.IP [3]
In the object itself.
.IP [4]
In the object's class.
.IP [5]
In the superclasses of the class, following each superclass in a depth-first
fashion in the natural order of the superclass list.
.PP
Any particular method implementation always comes as \fIlate\fR in the
resulting list of implementations as possible; this means that if some class,
A, is both mixed into a class, B, and is also a superclass of B, the instances
of B will always treat A as a superclass from the perspective of inheritance.
This is true even when the multiple inheritance is processed indirectly.
.SS FILTERS
.PP
When an object has a list of filter names set upon it, or is an instance of a
class (or has mixed in a class) that has a list of filter names set upon it,
before every invocation of any method the filters are processed. Filter
implementations are found in class traversal order, as are the lists of filter
names (each of which is traversed in natural list order). Explicitly invoking
