Version 1.8.7 patchlevel 0 Aug 10 2018

Major Changes

  • Support websocket connections. See https://github.com/grapenut/websockclient for a sample in-browser client. [Grapenut, 1007]
  • Change attributes from being stored in sorted linked lists to sorted arrays; results in faster lookups and less memory usage. [SW]
  • Penn now comes with the Sqlite3 database engine bundled with it, and uses it internally in a few ways:
    • 3 different tables for looking up color names are combined into a single table.
    • Per-object auxilliary data keys (objdata) are handled in sql.
    • Player names and alias lists are handled in sql, making some operations on them simpler.
    • Suggests alternatives for unknown function names, flags, powers and help entries, and a softcode interface to the suggestion engine.
    • @entrances and entrances() no longer scan the entire database.
    • Help files are stored in a database, with an expanded help/search that supports full text search. See HELP SEARCHING for details.
    • Optional enhanced connection logging. See the file game/CONNLOG.md for details.
    • A number of new softcode functions and expanded functions, listed below.

Minor Changes

  • Message translation support now defaults to off. Run configure with --enable-nls to turn it on if needed. [SW]
  • Shrink the NEW_PE_INFO struct, for signficant memory savings in softcode that queues lots of commands. [SW]
  • Add more test cases to the softcode test suite. [SW]
  • log_forces in mushcnf.dst now defaults to no. You probably only want this on if you're debugging. [MG]
  • The connect screen now respects SOCKSET options. [MG]
  • @chan/what now displays channel locks. [MT, 1208]

Softcode

  • Support all of Rhost's colors() key arguments (Except n). [SW, 1112]
  • Functions that work on integers (Like div() or band()) now use 64-bit values instead of 32-bit. [SW]
  • Added isjson()
  • json_query() get and exists can follow paths into objects instead of taking a single key/index. Suggested by qa'toq. [SW]
  • json_mod() for modifying complex JSON objects. [SW]
  • json_query(str, unescape) handles unicode escape sequences.
  • json(string, foo) escapes non-ascii characters.
  • clone() now takes an optional fourth argument to act like @clone/preserve [797]
  • New 'me' and 'inventory' flags for scan() give finer control of what to scan. [MG]
  • orflags(), orlflags(), andflags(), andlflags(), and the power versions no longer return errors on unknown flags/powers. They instead treat the unknown one as if it wasn't set. Suggested by Qon. [1180].
  • timecalc() and secscalc() for adding/subtracting intervals from times.
  • @suggest and suggest() for user-defined spellchecking. Loads /usr/share/dict/words or another configurable wordlist by default.
  • connlog() and connrecord() for interfacing with enhanced connection logs.
  • soundex() and soundslike() now support a second phonetic hash algorithm besides soundex.
  • Side-effect version of link() now returns 1 on success, 0 or #-1 on failure. [MT]
  • owner() now accepts two optional arguments, allowing ownership to be changed as in @chown and @atrchown. [MT]
  • If compiled with libcurl support, adds @http for interacting with RESTFul web APIs. [SW]
  • stripaccents() supports a second, smarter, transliteration algorithm.
  • If compiled with ICU support, adds lcstr2() and ucstr2() with proper support for characters like the German eszett (ß) that map to a different number of characters in different cases.
  • @chatformat now receives a new arg, %6, which defaults to "says" but may be replaced by the speechtext mogrifier. Inspired by Bodin. [MG]
  • etimefmt() supports $w and $y formats for weeks and years. [SW, 804]
  • Ported parenmatch() from Rhost. [MT, 1024]

Fixes

  • A bunch of color names weren't mapping correctly to Xterm color codes. [SW]
  • @grep/iprint hilites the matching text in the same case it appears in the attribute body. [SW, 1120]
  • @mail wasn't updating a player's MAILCURF attribute correctly. [CLDawes, 1131]
  • Connecting with a web browser to a mush without a mud_url config option set caused an infinite refresh loop. Reported by grapenut. [1149]
  • Make sure sigrecv_ack() won't hang the mush if it somehow gets called at the wrong time. Also fix a file descriptor leak in the signal handling code. [SW]
  • Pass pe_info into IDLE and HAVEN attributes from the page command. [MG]
  • The x and X options to align() now always truncate to the column width, rather than incorrectly truncating at a space. Reported by Qon. [MG, 1178]
  • json_query() didn't understand an action of 'type' as documented. [SW]
  • @clone without /preserve wasn't stripping privileged flags and such. [1190,SW]
  • @chown/preserve was resetting wiz-bit despite it's help file indicating otherwise. [1187] PR by Qon.
  • scan() now determines if objects will be included based on whether the caller can examine them, rather than if scan()'s <looker> can examine them. [MG]
  • Fixed some bugs regarding when setq() will and won't let you set the values of named registers when you've hit the limit. [MG, 1179]
  • sqlescape() when using a sqlite3 connection no longer also requires MySQL.
  • A number of issues in the handling UTF-8 text sent by clients have been fixed, as well as improvements in UTF-8 handling in general. [SW]
  • Fix an off-by-one error in command switch initialization code. [SW]
  • @mail without a message list respects the current folder instead of using folder 0. [77]
  • ufun(), ulocal(), etc. could get confused by ansi (markup) in the attribute name. Strip markup first. [MT]

Documentation

  • Changelogs and other documentation use markup. [SW, 1140]
  • Start trying to clean up and revise ancient documentation. [1095]
  • Help fixes and improvements. [MG, SW, MT]
  • Help files are now in UTF-8.

OS Specific

BSDs in general

  • info_slave and ssl_slave use kqueue() to efficiently be notified of parent mush crashes.

OpenBSD

  • netmush and slave processes use pledge(2) to limit their privileges. [SW]

Windows

  • Use Windows crypto library functions for base64 conversion and digest hashing instead of OpenSSL. [SW]
