Summary of Changes

• Changed Efuns:
  • load_object():The object name must not be empty (Bug #500).
• Fixed Crashers:
  • Size-changing mapping operations didn't fully check for destructed objects as keys, sometimes derefencing invalid pointers in the process (Bug #517).
  • Removed a crasher when running with --check-refcounts: References by snooping non-interactives weren't counted (Bug #492).
  • Loading an object with an empty name twice could crash the driver (Bug #500).
  • clone_object():When initializing a clone's variables using #pragma share_variables, really use the variables from the blueprint object being given. This allows the handling of inherited blueprint objects with replaced programs. (Bug #483)
  • An argument mismatch error during a lfun-closure call could crash the driver. (Bug #495).
  • The definition 'struct abc abc;' could crash the driver. (Bug #494)
  • The use of local undefined structs as struct abc abc = (<abc>) could crash the driver. (Bug #493)
• Compiler:
  • The lfuns backing the inline closures are again 'private nomask'.
• Runtime:
  • foreach(int i: num) recognizes if num is negative and throws an error. (Bug #503)
  • The handling of charmode with combine-charset could lead to premature socket closing if present with longer data than the input buffer could at one time. (Bug #442)
  • The Apply-Cache statistics counters should overflow less often (Bug #520).
  • If a simul_efun object appears before being 'blessed', that object is rejected to avoid variable/function inconsistency bugs. (Bug #489).
• Other:
  • The autoconfiguration of YACC was incompatible with gentoo Linux.
  • Removed a few (partly fatal) 64-bit issues (Bug #490, #491).
  • Removed a memory leak when catching errors inside master::runtime_error() (Bug #513).

Changelog

14-Oct-2007 (Lars Duening) 3.3.716

• Created snapshot.

14-Oct-2007 (Gnomi)

• (prolang.y, lex.c) UNKNOWN identifiers are kept around until the end of the compilation, as some parser rules can look-ahead multiple tokens pointing to the same UNKNOWN identifier, so an early free will lead to references to invalid memory. Keeping them that long is a bit of overkill, but more future-proof (Bug #494).
• (prolang.y) Struct names are searched only the global namespace as that is where structs are defined. Searched in the local namespace can get the driver confused with references to undefined structs. (Bug #493)
• (simul_efun.c) If a simul_efun object appeared before being blessed explicitely, it may be an old backup copy. This situation is now rejected as the variable/function definitions may differ subtly. (Bug #489)

13-Oct-2007 (Lars Duening)

• (interpret, simulate.c) Changed the apply cache counters to 'unsigned long' to reduce the possibility of an overflow (Bug #520).
• (interpret.c) setup_new_frame() now updates the csp->funstart entry by itself, instead of having the caller do it. This is not just more convenient, but also avoids problems with possible errors during its execution (as the error handling will try to create a stack trace). (Bug #495)

07-Oct-2007 (Lars Duening)

• (comm.c) When in charmode, don't attempt to read in as much data as the buffer has left space: otherwise the handling of such an 'overlong command' confuses the charmode engine and causes the socket to close prematurely. Yes, this is more a workaround than a real fix (Bug #442).
• (simulate, interpret) The value thrown in a catch is now held in the catch context could be leaked if a second error happens and is caught in the master::runtime_error() handler (Bug #513).
• (configure) When testing for libiconv, reference a real libiconv method. This catches situations where libiconv exists, but is of the wrong architecture.

06-Oct-2007 (Lars Duening)

• (configure) gentoo Linux requires the '-n' argument for 'tail +2' to work correctly (thanks, Juanjo!).
• (comm.c) Removed a crasher when running with --check-refcounts: References by snooping non-interactives weren't counted (Bug #492).
• (sprintf.c) Removed a 64-bit issue (comparison of two values with differing value ranges) (Bug #490)
• (prolang.y) upd_long() and read_long() weren't 64-bit-safe (even though ins_long() already was) (Bug 491).
• (prolang.y) With the corrections to the inheritance handling done some time ago, the lfuns backing inline closure can be again made 'private nomask' (Bug #511).
• (simulate.c) load_object(): The object filename to load must not be empty (Bug #500).
• (mstrings, obtable.c) Made sure that otable uses the same hasher as mstring (Bug #500).
• (object, simulate.c) clone_object(): When initializing a clone's variables using #pragma share_variables, really use the variables from the blueprint object being given, not relying on the program. This allows the handling of inherited blueprint objects with replaced programs. (Bug #483)
• (simulate.c) replace_program(): If the program of a blueprint is replaced, the old program's blueprint pointer is NULLed out as it is no longer accurate. (Bug #483)
• (mudlib/uni-crasher/crasher.c) 'New' version from Bug #91.
• (my-rusage.h, files.c) Removed obsolete macro PROT() (Bug #504).
• (interpret.c) foreach(int i : negative number) now throws an error (Bug #503).

03-Oct-2007 (Lars Duening)

• (mapping.c, object.c) Removed C-99 features.

01-Oct-2007 (Gnomi)

• (mapping.c) resize_mapping() didn't check for destructed objects as keys, which made operations like map-([0]) after an object destruction potentially fatal (Bug #517).
