Summary of Changes

Changed efuns:
- save_value(), restore_value(), save_object(), restore_object(): lfun closures are now saved with their inheritance path to allow proper restoration under complex circumstances.
- tls_check_certificate(): GEN_DNS, GEN_EMAIL and GEN_URI certificates are supported.
New efuns:
- hash(): Available if OpenSSL is supported, this efun calculates hashes for various methods.
- hmac(): Available if OpenSSL is supported, this efun calculates HMACs for various methods.
- tls_refresh_certs(): Reload the certificates and certificate revocation information.
Compiler:
- If a non-virtual baseclass was inherited multiple times with a virtual class inside the inheritance tree, its members were merged even though they shouldn't.
- The type tracking was improved so that variable initializations like int i = to_int( ({float})0 ); compile correctly.
- New macros __OPENSSL__and __GNUTLS__offer insight as to which TLS package is being used.
- Lfun closures now keep proper track of which program they belong to.
- Apply cache entries for non-existing functions could lead to memory corruption as result of garbage collection.
Language:
- array & mapping implements the intersection of the array with the indices of mapping.
Other Changes:
- New commandline options to handle certification revocations: --tls-crlfile and --tls-crldirectory.

Changelog

30-Sep-2007 (Lars Duening) 3.3.715 = 3.4.2

Released as 3.4.2.

04-Nov-2006 (Lars Duening, Philip Hancke)

(pkg-tls, main.c) Added new options --tls-crlfile and --tls-crldirectory to hold the Certificate Revocation information.
(pkg-tls, func_spec) New efun tls_refresh_certs() to reload the certificates and certificate revocations.

09-Jul-2006 (Lars Duening) (3.3.714)

Created snapshot.

14-Jun-2006 (Lars Duening)

(array.c) Removed a memory leak when array intersection or subtraction failed.
(mapping, array, interpret.c, prolang.y) Implemented the array/mapping intersection.

12-Jun-2006 (Lars Duening)

Oh dear, has it been that long?
(make_func.y) Modified a case of undefined behaviour in the creation of the character classification tables: only 'unsigned char' types have a defined overflow behaviour (thanks, Erik!)
(configure) -fno-force-mem is deprecated.

09-May-2006 (Lars Duening)

(xalloc.c) If the driver runs low on memory, it also prints the current object and program in the low-on-memory message.

06-May-2006 (Lars Duening)

(pkg-tls) New efuns hash() and hmac() offer flexible hash and HMAC calculation if the driver is compiled to use OpenSSL (provided by Philipp).
(pkg-tls.c) Removed a compilation error occuring with GnuTLS.
(lex.c) New macros __OPENSSL__ and __GNUTLS__ are set depending on which TLS package is being used.

06-May-2006 (Gnomi)

(prolang.y) Corrected the linenumber counting for inline closures.

23-Apr-2006 (Lars Duening)

(mstring) The max hash length used is now available as macro constant.
(otable.c) Both mstrings and C-strings are hashed with the same max length. This corrects a bug with extremely long object names (Bug #466).
(structs.c) The calculation of the first part of a struct's hash uses what the mstring code has already calculated.

30-Mar-2006 (Lars Duening)

(prolang.y) Removed a dead branch.
(pkg-tls.c) Removed a possible compiler warning (Bug #464).
(prolang.y) Removed a bison warning when structs aren't used.

27-Mar-2006 (Lars Duening)

(pkg-tls.c) Added support for GEN_EMAIL, GEN_URI and GEN_DNS certificates. tls_verify_callback() now prints diagnostics only if the '-d' option was given (thanks, Philipp).

18-Mar-2006 (Gnomi)

(interpret.c) In apply cache entries for non-existing functions, the garbage collector counted the reference to the string name twice, causing the use of deallocated memory (Bug #463).

16-Mar-2006 (Lars Duening)

(comm.c) Moved the declaration of a variable which was declared in the middle of a block - gcc doesn't complain, but it's not ISO-C (Bug #462).

14-Mar-2006 (Gnomi)

(closure, object.c, interpret, exec.h, gcollect.c) lfun closures now keep track to which program they belong, to avoid ambiguities in case of complex inheritance relationships. This also affects the savefile format: lfun closures are saved with their inheritance path (Bug #443, #444).
(prolang.y) If a non-virtual baseclass was inherited multiple times with a virtual class inside the inheritance tree, its members were merged even though they shouldn't (Bug #422).
(prolang.y) The LPC compiler used a global variable for typetracking, which caused errors when types changed inside a variable initialisation (Bug #394).

12-Mar-2006 (Lars Duening) (3.3.713)

Created snapshot.
(comm.c) Master function disconnect() receives the remaining input data is passed as the second argument (suggested by Philipp).

08-Mar-2006 (Malcom Tester)

(lp-245/obj/master.c) Made the move implementation more robust.

07-Mar-2006 (Lars Duening)

(pkg-tls.c) Two modifications to increase reconnect stability (thanks, Philipp!).
(prolang.y) Extended a LPC compiler warning when function indices are adjusted.

06-Mar-2006 (Lars Duening)

(backend, comm.c, object) The logon(obj) function moved from backend.c into object.c, and was renamed logon_object() - it's more sensical this way.
(comm.c) If the master::connect() initiates a secure connection which gets stuck in the handshake, neither logon() is called nor is the prompt printed. Also, if the tls_init_connection() didn't set a callback, the driver will provide a callback to logon(). This way logon() won't be called unless the connection is up and running.
(mudlib/psyc-tls.c) Example for using the tls_check_certificate() efun (thanks, Philipp).

03-Mar-2006 (Lars Duening)

(pkg-tls.c) tls_check_certificate() does more interpretation of the result and returns better data (provided by Philipp).

01-Mar-2006 (Lars Duening)

(interpret.c) A missing return is noted at runtime only once per function. This is achieved by runtime code modification, but we do that for switch() as well (Bug #430).

28-Feb-2006 (Lars Duening)

(pkg-idna) Added support for International Domain Names (provided by Philipp - thanks!).
(configure, Makefile) Added a target 'install-headers' to install all driver LPC header files.
(simulate.c) Virtual blueprint objects are guaranteed to have their 'clone' flag unset.
(string_spec, simulate.c) Renamed COMP_OBJ to the more intuitive COMPILE_OBJECT.
(interpret.c) Removed the stipulation that CATCH_RESERVED_COST must be twice as much as MASTER_RESERVED_COST, since the master reserve is used automatically anyway (suggested by Gnomi).
(efuns.c) sscanf(): The new modifier '+' requires the matching of the characters after a field in order to consider the field as matched.

20-Feb-2006 (Lars Duening)

(Makefile.in) Added a dependency to create patchlevel.h, even if the program is made with 'make ldmud'.

20-Feb-2006 (Gnomi)

(comm.c) remove_interactive() clobbered the current_object, setting it to NULL. It is now preserved (Bug #431).
(interpret.c) When executing an efun closure, the tracedepth wasn't incremented accordingly (Bug #441).
(simulate.c) When executing a non-toplevel callback, the tracedepth should not be zeroed out (Bug #441).

08-Jan-2006 (Lars Duening)

(make_func.y) When parsing the func_spec file, the preprocessor conditionals were handled in a buffer in a no-longer existing stack frame. So far, we were lucky, but on a 64-bit machine that space was needed by the Bison parser.
(driver.h, smalloc.c, slaballoc.c) If the machine uses a 8-Byte malloc alignment (e.g. all PowerPC machines), the allocator does not replace the system malloc().
(mud/lp-245/) Since the recent change to how simul_efuns are called (see Bug #419), the LP-245 lib was broken. This has been corrected.

05-Dec-2005 (Lars Duening)

(configure, machine.h.in, config.h.in) Added a configuration check for SQLite3.
(pkg-sqlite, many files) Added SQLite support (Bug #11).

04-Dec-2005 (Gnomi)

(prolang.y) Private lfuns no longer hide simul-efuns.
(prolang.y) Private lfuns can be hidden by public functions without warning, ie. the former are now really invisible to inheritors. This also corrects a crasher with multi-level virtual inherits.
(prolang.y) Multiple virtual inheritance of the same program with changing visibility is now handled with a better calculation of the final visibilities. (Bug #362)

04-Dec-2005 (Lars Duening)

(interpret.c) Calling an unbound lambda cleaned the control stack twice, causing errors (Bug #374).
(simul_efun.c) Only public simul-efuns can be called. This was always valid for sefuns outside the 256-range, but now also applies to normal sefuns as well (Bug #419)
(simul_efun, prolang.y, closure.c, interpret.c) The number of direct callable simul-efuns is now configurable in the simul_efun.h. I also increased it to 65536 from 256.
(closure.c) Simul-efuns were still called with call_other instead of call_direct.

02-Dec-2005 (Lars Duening)

(gcollect.c) Added a log output when all objects are data-cleaned, as it might be the cause for some observed slowdowns.
(closure.c, interpret.c) For completeness sake: removed the compilation errors happening when disabling the new inline closures (Bug #423).

27-Nov-2005 (Lars Duening)

(object.c) Efun present(): Modified the search behaviour so that the numbering is applied over both inventory and environment together. Before, the numbering was individual in each space, leading to situations where low-numbered objects in the environment were hidden by those in the inventory (Bug #417).
(object.c) Efun function_exists(): The 'FEXISTS_ALL' result also contains information about the function's type, flags, and number of arguments (Bug #410).

26-Nov-2005 (Lars Duening)

(efuns.c) Efun sscanf(): Added test whether the constant characters after a %-field also match - if not, the %-field is considered unmatched (suggested by Largo).
(efuns, func_spec) Efuns md5()/sha1(): Accept the number of iterations as optional argument (Bug #418).
