* * generic/tclLiteral.c (TclCleanupLiteralTable): Correcteddgp2004-08-021-21/+42
| | | | | | * tests/compile.test (compile-12.4): flawed deletion of literal internal reps that could lead to accessing of freed memory. Thanks to Kevin Kenny for test case and fix [Bug 1001997].
* 2004-07-21 Kevin Kenny <kennykb@acm.org>Kevin B Kenny2004-07-211-1/+54
| | | | | | | | | | | | | * generic/tclBasic.c (DeleteInterpProc): * generic/tclLiteral.c (TclCleanupLiteralTable): * generic/tclInt.h: added a TclCleanupLiteralTable function, called from DeleteInterpProc, that frees internal representations of shared literals early when an interpreter is being deleted. This change corrects a number of memory mismanagement issues in the cases where the internal representation of one literal contains a reference to another, and avoids conditions such as resolved variable names referring to procedure and namespace contexts that no longer exist. [Bug 994838]

| | | | | | | | | * generic/tclLiteral.c (TclReleaseLiteral): fix for [Bug 467523], which resurfaced with the latest changes. The previous strategy was to have special code in TclReleaseLiteral to handle the self-references generated by empty scripts. The new approach avoids the self-reference altogether, by having empty scripts return an unshared literal.

* * generic/tclBasic.c (DeleteInterpProc): fix for [Bug 983660],Miguel Sofer2004-07-051-17/+17
| | | | | | | | | found by pspjuth. Tear down the global namespace before freeing the interp handle, to allow the bytecodes to free their non-shared literals. * generic/tclLiteral.c (TclReleaseLiteral): moved special code for self-ref so that it is also used for non-shared literals. Possible bug found by inspection.

| | | | | | | | | | | | | | | | | | | | | | | * generic/tclInt.h: Reworked the Tcl header files into a clean * unix/tclUnixPort.h: hierarchy where tcl.h < tclPort.h < tclInt.h * win/tclWinInt.h: and every C source file should #include * win/tclWinPort.h: at most one of those files to satisfy its declaration needs. tclWinInt.h and tclWinPort.h also better organized so that tclWinPort.h includes the Windows implementation of cross-platform declarations, while tclWinInt.h makes declarations that are available on Windows only. * generic/tclBinary.c (TCL_NO_MATH): Deleted the generic/tclMath.h * generic/tclMath.h (removed): header file. The internal Tcl * macosx/Makefile (PRIVATE_HEADERS): header, tclInt.h, has a * win/tcl.dsp: #include <math.h> directly, and file external to Tcl needing libm should do the same. * win/Makefile.in (WIN_OBJS): Deleted the win/tclWinMtherr.c file. * win/makefile.bc (TCLOBJS): It's a vestige from matherr() days * win/makefile.vc (TCLOBJS): gone by. * win/tcl.dsp: * win/tclWinMtherr.c (removed):
