<code>member()</code>, <code>rmember()</code>: The start position for the search can be specified. <li> <code>mkmapping()</code>: Convert structs to mappings, too. <li> <code>pg_*()</code>: Postgres efuns trigger a privilege violation ("pgsql", "<em>efun name</em>"). <li> <code>process_string()</code>: Spaces are now allowed in function arguments and no longer terminate the function specification. <li> <code>regexp()</code>, <code>regexplode()</code>: Optionally take RE interpretation options. <li> <code>regexplode()</code>: New flag RE_OMIT_DELIM allows to omit the matched delimiters from the result. <li> <code>send_erq()</code>: ERQ callback closures can now accept the data as a string instead of an array. <li> <code>sprintf()</code>, <code>printf()</code>: Formats %O and %Q print floats always with a decimal point. <li> <code>say()</code>, <code>tell_room()</code>, <code>tell_object()</code>: The efuns can now take a mapping, an object or a struct instead of an array to use with the <code>catch_msg()</code> mechanism. <li> <code>transfer()</code>: Available (in compat mode) only when USE_DEPRECATED is in effect. <li> <code>unique_array()</code> The separator function can now be a closure, and can also be given extra arguments. <li> <code>wizlist_info()</code>: Added the number of mappings to the result. <li> <code>write_file()</code> Allowed to remove the

structs. <li> <code>call_direct</code>(), <code>call_direct_resolved()</code>: To perform calls which are not resolved by a default method. <li> <code>convert_charset()</code>: Convert a string between character sets. <li> <code>match_command()</code>: Find all matching actions for a command. <li> <code>md5_crypt()</code>: Compute an Apache-compatible password encryption using the MD5 message digest algorithm. <li> <code>pg_connect()</code>, <code>pg_query()</code>, <code>pg_pending()</code>, <code>pg_close()</code>: Optional: PostgreSQL support. <li> <code>regmatch()</code>: To match a string against a regexp and optionally retrieve the match results for subexpressions. <li> <code>regexp_package()</code>: Returns the currently selected default regexp package. <li> <code>reverse()</code>: Reverse the content of an integer, a string or an array. <li> <code>sha1()</code>: Compute the SHA1 message digest. <li> <code>struct_info()</code>: Return information about a struct. <li> <code>structp()</code>: Predicate to detect struct values. <li> <code>to_struct()</code>: Convert an array into a struct. </ul> <li> Master Object: <ul> <li> Function <code>runtime_warning()</code> is called for runtime warnings. <li> <code>privilege_violation()</code>: For "set_limits" and "limited" the requested limits are passed as argument. <li> During the compilation of the master object, simul-efuns are disabled (so they won't be used by accident). </ul> <li> Fixed Crashers: <ul> <li> Removed a crasher when a private lfun shadowing a public sefun was virtually inherited twice in parallel. <li> Removed a crasher when a <code>walk_mapping()</code> over a mapping deleted elements from the very same mapping. </ul> <li> Language: <ul> <li> New operator <code>...</code> to flatten array arguments in a function call at runtime. <li> Strings can now hold all characters, including '\0'. <li> <code>foreach()</code> can loop over references, integers and integer ranges. <li> <code>nosave</code> and <code>catch(; nolog)</code> are now official features. <li> New indexing method <code>[>]</code> to index either from the beginning or the end, depending on the sign of the index value. <li> New pragma <code>range_check</code> allows to check array range indexing at runtime. <li> If <code>switch()</code> is used on a value which is neither a string nor a number, the driver no longer generates a runtime error messge, but instead jumps to the <code>default</code> label. <li> Operators <code>|</code> and <code>|=</code> can compute the union of two arrays. <li> Operators <code>^</code> and <code>^=</code> can compute the symmetric difference of two arrays. <li> Closure operators <code>#'|</code> and <code>#'^</code> can take more than two arguments. <li> Support for structs; preprocessor symbol <code>__LPC_STRUCTS__</code> is defined. <li> Preprocessor symbol <code>__PCRE__</code> is always defined. <li> Real inline closures; preprocessor symbol <code>__LPC_INLINE_CLOSURES__</code> is defined. <li> New macro <code>__BOOT_TIME__</code> expands to the time() the driver was started. <li> Blueprint variables are now always initialized using <code>__INIT()</code>. Clone variables are usually initialized the same way, however with the pragmas <code>share_variables</code> and <code>init_variables</code> the programmer can instruct the driver on a pre-program basis to initialize the variables of clone from the current values of the corresponding variables in the blueprint. <li> Bugfix: The type recognition of the variables for a <code>foreach()</code> no longer gets confused by visibility flags. </ul> <li> Runtime: <ul> <li> Revamped the string handling to use refcounted strings everywhere. <li> If input is requested in CHARMODE, the NL characters are passed verbatim to the caller (old drivers passed an empty string instead). <li> The driver hook <code>H_DEFAULT_METHOD</code> can be used to resolve <code>call_other()</code>/<code>call_resolved()</code>s to non-existing functions. <li> The driver hook <code>H_DEFAULT_PROMPT</code> can be used to specify a default prompt different from "> ". <li> The driver hook <code>H_PRINT_PROMPT</code> can be used to do special magic when printing the prompt. <li> The driver regularly checks the variables of all objects for references to destructed objects and removes them; it is therefore no longer necessary to "clean" mappings by hand. <li> The driver can now warn about missing return statements for value returning functions (this applies only for functions with a specified return type). If possible the driver tries to detect this situation at compile time, but also inserts a special 'return' bytecode to catch certain pathological cases at runtime. The check is controlled by the pragma '(<code>no_</code>)<code>warn_missing_return</code>'. <li> New runtime 'limit' <code>LIMIT_COST</code> to control how much a limited execution should cost. <li> The basic timing granularity and the heartbeat interval time can be configured at compile time and with the commandline options <code>--alarm-time</code> and <code>--heart-interval</code>. The values are available in LPC with the macros <code>__ALARM_TIME__</code> and <code>__HEART_BEAT_INTERVAL__</code>. <li> Heartbeats can be executed synchronously (all at the same time as far as granularity allows, regardless of when inside one hb interval they have executed last). The commandline options are <code>--sync-heart</code> and <code>--async-heart</code>; if enabled, the macro <code>__SYNCHRONOUS_HEART_BEAT__</code> is defined. </ul> <li> Other Changes: <ul> <li> The input escape character can be configured at compile time to something different from '!'. <li> The MAX_MAPPING configuration parameter now determines the total number of elements (keys + values) a mapping can hold, not just the maximum number of keys. <li> The driver can be configured to use either the traditional regular expression code, or the PCRE package. <li> New commandline options <code>--share-variables</code> and <code>--init-variables</code> to defined the default for clone variable initialization. <li> New configuration option <code>--enable-malloc-sbrk</code> to selectively allow the memory allocator to use sbrk() instead of malloc() where available (default is to allow sbrk()). <li> New commandline options <code>--tls-key</code> and <code>--tls-cert</code> to define the x509 key- and certfile for the TLS package. </ul> </ul> <p> <font size="-1">(Back to the <a href="#top">top</a>.)</font> <hr>  <h5>30-Sep-2007 (Lars Duening) <a name="342">3.3.715 = 3.4.2</a> <font size="-1">(<a href="#summary342">Change Summary</a>)</font> </h5> <ul type="square"> <li> Created snapshot. </ul> <h5>04-Nov-2006 (Lars Duening, Philip Hancke)</h5> <ul type="square"> <li> (pkg-tls, main.c) Added new options --tls-crlfile and --tls-crldirectory to hold the Certificate Revocation information. <li> (pkg-tls, func_spec) New efun tls_refresh_certs() to reload the certificates and certificate revocations. </ul> <h5>09-Jul-2006 (Lars Duening) <a name="33714">3.3.714</a> </h5> <ul type="square"> <li> Created snapshot. </ul> <h5>14-Jun-2006 (Lars Duening)</h5> <ul type="square"> <li> (array.c) Removed a memory leak when array intersection or subtraction failed. <li> (mapping, array, interpret.c, prolang.y) Implemented the array/mapping intersection. </ul> <h5>12-Jun-2006 (Lars Duening)</h5> <ul type="square"> <li> Oh dear, has it been that long? <li> (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!) <li> (configure) -fno-force-mem is deprecated. </ul> <h5>09-May-2006 (Lars Duening)</h5> <ul type="square"> <li> (xalloc.c) If the driver runs low on memory, it also prints the current object and program in the low-on-memory message. </ul> <h5>06-May-2006 (Lars Duening)</h5> <ul type="square"> <li> (pkg-tls) New efuns hash() and hmac() offer flexible hash and HMAC calculation if the driver is compiled to use OpenSSL (provided by Philipp). <li> (pkg-tls.c) Removed a compilation error occuring with GnuTLS. <li> (lex.c) New macros __OPENSSL__ and __GNUTLS__ are set depending on which TLS package is being used. </ul> <h5>06-May-2006 (Gnomi)</h5> <ul type="square"> <li> (prolang.y) Corrected the linenumber counting for inline closures. </ul> <h5>23-Apr-2006 (Lars Duening)</h5> <ul type="square"> <li> (mstring) The max hash length used is now available as macro constant. <li> (otable.c) Both mstrings and C-strings are hashed with the same max length. This corrects a bug with extremely long object names (Bug <a href="http://mantis.bearnip.com/view.php?id=466">#466</a>). <li> (structs.c) The calculation of the first part of a struct's hash uses what the mstring code has already calculated. </ul> <h5>30-Mar-2006 (Lars Duening)</h5> <ul type="square"> <li> (prolang.y) Removed a dead branch. <li> (pkg-tls.c) Removed a possible compiler warning (Bug <a href="http://mantis.bearnip.com/view.php?id=464">#464</a>). <li> (prolang.y) Removed a bison warning when structs aren't used. </ul> <h5>27-Mar-2006 (Lars Duening)</h5> <ul type="square"> <li> (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). </ul> <h5>18-Mar-2006 (Gnomi)</h5> <ul type="square"> <li> (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 <a href="http://mantis.bearnip.com/view.php?id=463">#463</a>). </ul> <h5>16-Mar-2006 (Lars Duening)</h5> <ul type="square"> <li> (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 <a href="http://mantis.bearnip.com/view.php?id=462">#462</a>). </ul> <h5>14-Mar-2006 (Gnomi)</h5> <ul type="square"> <li> (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 <a href="http://mantis.bearnip.com/view.php?id=443">#443</a>, <a href="http://mantis.bearnip.com/view.php?id=444">#444</a>). <li> (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 <a href="http://mantis.bearnip.com/view.php?id=422">#422</a>). <li> (prolang.y) The LPC compiler used a global variable for typetracking, which caused errors when types changed inside a variable initialisation (Bug <a href="http://mantis.bearnip.com/view.php?id=394">#394</a>). </ul> <h5>12-Mar-2006 (Lars Duening) <a name="33713">3.3.713</a></h5> <ul type="square"> <li> Created snapshot. <li> (comm.c) Master function disconnect() receives the remaining input data is passed as the second argument (suggested by Philipp). </ul> <h5>08-Mar-2006 (Malcom Tester)</h5> <ul type="square"> <li> (lp-245/obj/master.c) Made the move implementation more robust. </ul> <h5>07-Mar-2006 (Lars Duening)</h5> <ul type="square"> <li> (pkg-tls.c) Two modifications to increase reconnect stability (thanks, Philipp!). <li> (prolang.y) Extended a LPC compiler warning when function indices are adjusted. </ul> <h5>06-Mar-2006 (Lars Duening)</h5> <ul type="square"> <li> (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. <li> (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. <li> (mudlib/psyc-tls.c) Example for using the tls_check_certificate() efun (thanks, Philipp). </ul> <h5>03-Mar-2006 (Lars Duening)</h5> <ul type="square"> <li> (pkg-tls.c) tls_check_certificate() does more interpretation of the result and returns better data (provided by Philipp). </ul> <h5>01-Mar-2006 (Lars Duening)</h5> <ul type="square"> <li> (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 <a href="http://mantis.bearnip.com/view.php?id=430">#430</a>). </ul> <h5>28-Feb-2006 (Lars Duening)</h5> <ul type="square"> <li> (pkg-idna) Added support for International Domain Names (provided by Philipp - thanks!). <li> (configure, Makefile) Added a target 'install-headers' to install all driver LPC header files. <li> (simulate.c) Virtual blueprint objects are guaranteed to have their 'clone' flag unset. <li> (string_spec, simulate.c) Renamed COMP_OBJ to the more intuitive COMPILE_OBJECT. <li> (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). <li> (efuns.c) sscanf(): The new modifier '+' requires the matching of the characters after a field in order to consider the field as matched. </ul> <h5>20-Feb-2006 (Lars Duening)</h5> <ul type="square"> <li> (Makefile.in) Added a dependency to create patchlevel.h, even if the program is made with 'make ldmud'. </ul> <h5>20-Feb-2006 (Gnomi)</h5> <ul type="square"> <li> (comm.c) remove_interactive() clobbered the current_object, setting it to NULL. It is now preserved (Bug <a href="http://mantis.bearnip.com/view.php?id=431">#431</a>). <li> (interpret.c) When executing an efun closure, the tracedepth wasn't incremented accordingly (Bug <a href="http://mantis.bearnip.com/view.php?id=441">#441</a>). <li> (simulate.c) When executing a non-toplevel callback, the tracedepth should not be zeroed out (Bug <a href="http://mantis.bearnip.com/view.php?id=441">#441</a>). </ul> <h5>08-Jan-2006 (Lars Duening)</h5> <ul type="square"> <li> (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. <li> (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(). <li> (mud/lp-245/) Since the recent change to how simul_efuns are called (see Bug <a href="http://mantis.bearnip.com/view.php?id=419">#419</a>), the LP-245 lib was broken. This has been corrected. </ul> <h5>05-Dec-2005 (Lars Duening)</h5> <ul type="square"> <li> (configure, machine.h.in, config.h.in) Added a configuration check for SQLite3. <li> (pkg-sqlite, many files) Added SQLite support (Bug <a href="http://mantis.bearnip.com/view.php?id=11">#11</a>). </ul> <h5>04-Dec-2005 (Gnomi)</h5> <ul type="square"> <li> (prolang.y) Private lfuns no longer hide simul-efuns. <li> (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. <li> (prolang.y) Multiple virtual inheritance of the same program with changing visibility is now handled with a better calculation of the final visibilities. (Bug <a href="http://mantis.bearnip.com/view.php?id=362">#362</a>) </ul> <h5>04-Dec-2005 (Lars Duening)</h5> <ul type="square"> <li> (interpret.c) Calling an unbound lambda cleaned the control stack twice, causing errors (Bug <a href="http://mantis.bearnip.com/view.php?id=374">#374</a>). <li> (simul_efun.c) Only public simul-efuns can be called.
