The projected official + release date is 09-02-96. +* Tweaks of numeric character reference handling. - FM +* Typo fix in LYShowInfo.c. - IC +08-28-96 +* Added handling of ENCTYPE="application/sgml-form-urlencoded" in FORMs + as a directive to use semi-colons instead of ampersands as name=value + separators, and to indicate that as the Content-Type for POSTs. - FM +* Convert ampersands in addresses and link names, and angle-brackets in + link names, to SGML entities when creating bookmarks and showinfo ('=') + link 'l'ist, client-side-image-map, and history list text/html streams + or temporary files. - FM +* More SGML compliance mods for the handling of attribute values which + represent URLs or URL components. - FM +* Tweaks of form INPUT, TEXTAREA, SELECT and OPTION handling. - FM +* Check EAGAIN on socket connect or select attempts for all platforms and + flavors. - FM +* Include both <time.h> and <sys/time.h> in tcp.h for AIX. +* Adding warning and info in the INSTALLATION file and userdefs.h on how + to cope with telnetd environment variable spamming for anonymous accounts + running Lynx captively. - FM +08-24-96 +* Enhancements of the History List handling. Show each link's actual address + in addition to the titles, since the actual addresses can't be determined + via showinfo or the 'l'ist display, and links in the History List derived + from searches can have the same titles but different searchparts or hidden + content appended. If a link in the History List is activated, is still + cached, has POST content, and ALWAYS_RESUBMIT_POSTS was configured off (as + recommended) and wasn't toggled on via -resubmit_posts, prompt the user + whether to resubmit the form (versus retrieve the cached rendition from + the previous submission). We don't bother prompting on PREV_DOC ("back") + fetches, and still resubmit forms with POST content whenever their submit + buttons are activated, i.e., regardless of whether ALWAYS_RESUBMIT_POSTS + has been configured or toggled on. - FM +* If a user attempts to add a bookmark while viewing a document returned + via a form submission with POST content, and it contains links, offer + the current link with it's link name for editing. Otherwise, display + a statusline message that documents from forms with POST content cannot + be saved as bookmarks. - FM +08-23-96 +* Added UP_HALF and DOWN_HALF commands, mapped by default to '(' and ')', + for going back or forward half a page in the document. These are + complementary to UP_TWO and DOWN_TWO, for going back or forward two + lines (remember to use the 'K'eymap command for a list of all of the + keystroke command bindings currently in effect, since they may have + been changed via lynx.cfg from the defaults described in the online + 'H'elp). - FM +* Made the Control-A and Control-E keys default synonyms for HOME and END, + complementary to their use for going to the beginning or end of the line + when using the line editor. - FM +* Don't lose track of source versus present mode on returns from temporary + menu files to documents derived from forms with method POST. - FM +* Ugh, I had deleted one too many lines from HTTP.c when stripping out my + SSL hooks for the distribution copy (no wonder the Authorization mods + worked fine for me but nobody else 8-). - FM +08-22-96 +* Added handling of named entities and numeric character references in + the values of most of the non-URL attributes (we don't waste overhead + doing that for the values of simple attributes, like ALIGN, which have + designated strings). - FM +08-21-96 +* Safely handle named entities and numeric character references in the values + of BASE, LINK, HREF, SRC, ACTION, DATA, CODEBASE and CODE attributes, and + in the URL field for the CONTENT of META with a "Refresh" HTTP-EQUIV or + NAME. They are converted in relation to the "ISO Latin 1" Character Set + array regardless of the selected Character Set (except that nbsp and shy + remain 160 and 173), then 8-bit translations are hex escaped (as they + should have been in the markup 8-), and ESC is hex escaped or omitted + depending on whether a CJK character set has been selected. There's no + way to do it such that the resolved URL always will be valid no matter + what yoyos or CGI scripts put in document instances, but this strategy + maximizes the chances while making sure no "dangerous" characters, based + on the selected Character Set, are ever sent to the screen (it used to be + HyperText Markup Language, not HyperGraphic Markup Language 8-)- FM +* Allow Control-G or a zero-length username or password to act as a cancel + of the request (and restoration of the current document) when an http + server invokes prompting for Authorization. - FM +* When using a proxy server, report the target host instead of the proxy + in prompts for Authorization. - FM +* Show MIME types of files, if known, whenever a download offer is forced, + regardless of why it was forced (i.e, not only for mismatches between + the document's charset and the selected character set). - FM +08-20-96 +* Yet more tweaks of MIME header parsing. - FM +08-19-96 +* Enhancements of the news gateway. - FM +* Tweaks of Content-Type and charset handling. - FM +* Tweaks of MIME header parsing. - FM +08-18-96 +* Tweaks of the news gateway and its documentation. - FM +08-17-96 +* Added overt (rational 8-) handling of all status codes that might be + returned (appropriately or inappropriately 8-) from HTTP/1.1 http + servers, and massively annotated the code in HTTP.c. - FM +* Added parsing in HTMIME.c, and at least trace mode reporting, for all + http server reply and entity headers as in the 08-12-96 HTTP/1.1 draft. + We should not get many of them, unless we declare ourselves as an HTTP/1.1 + client and send the appropriate request headers, but they're all available + now for use as more HTTP/1.1 features are added. - FM +08-16-96 +* Added handling of "Pragma: no-cache" or "Cache-Control: no-cache" headers + from http servers, and polished up the code for handling them via META + directives. - FM +08-15-96 +* Modified form handling so that Lynx always resubmits forms if their method + is POST, even if their content was not changed, when their submit buttons + or submitting text input are activated. Changed the ALWAYS_RESUBMIT_FORMS + compilation and configuration definitions, and -resubmit_forms command + line toggle, to ALWAYS_RESUBMIT_POSTS, and -resubmit_posts. When FALSE, + you still get the previously returned document from a POSTed form if that + document had links which you activated, and then go back with the PREV_DOC + command or via the history list. If set TRUE, the form will be resubmitted + under those circumstances as well. Documents returned by forms with method + GET still require use of the RESUBMIT command to resubmit if the forms' + content was not changed, and forms with a mailto action still always mail + the content on activation of the submit button or submitting text input + (no document is returned, so the PREV_DOC command and history list behaviors + are irrelevant). - FM +* Use space to plus conversions for values of submitted form content (Ugh, + Lynx has been using %20 all these years! It worked because they are + unescaped to space, anyway. 8-). - FM +* Polished up and massively annotated the redirection handling code. If + a user approves redirection of a form with POST content, it will not be + freed and the submission will not be converted to a contentless GET request + unless the status was 303 (See Other). For 300 (Multiple Choices), the + returned document is offered, which should include links with descriptions + of their media types. The returned document (if any) is now displayed for + any redirection status code if no Location: header was present, and for + unknown 3xx codes (i.e., greater than 305). If Lynx gets an inappropriate + 304 (Not Modified), it switches to HEAD mode and displays the status line, + and anything else returned by the server, as text/plain. A 301 (Moved + Permanently) will be treated as 302 (Moved Temporarily) for form submissions + with POST content. Otherwise, Lynx will use the new URL for the remainder + of the current session (users will have to do a 'r'emove and 'a'dd for their + bookmarks themselves, for now). A 305 (Use Proxy) will not be honored if + Lynx is already using a proxy, and instead the returned document will be + displayed. The limit on serial redirections was dropped from the current + 10 to 5, as recommended in the August 10, 1996 HTTP/1.1 draft. - FM +08-13-96 +* Mods to accommodate the HTTP/1.1 300 - 305 Redirection status codes, and + to require user confirmation for any redirection of POST content. - FM +* Tweaks of OBJECT handling. - FM +08-12-96 +* Implemented all aspects of OBJECT that make sense for a text client. + Will descend though nested OBJECTs. Can be used for presenting PRE + formatted character-cell versions of images, and appears to handle + all likely uses of the SHAPES and USEMAP attributes in OBJECTs. The + pseudo-ALTs for links to non-script DATA values (i.e, the for-GUI + sources) when offered as links (e.g., in clickable_images mode), if + not a markup-specified string (e.g., based on a TITLE attribute), + are (IMAGE) or (OBJECT), based on whether the nature of the source + can be inferred from the context, or an explicit TYPE attribute in + the OBJECT start tag. The use of parens instead of square-brackets + indicates that the links are for OBJECTs as opposed to IMGs. - FM +* Tweaks of SELECT and OPTION handling. - FM +08-09-96 +* Lots more stuff added to the online help files. - FM +* Added state code in SGML.c to avoid getting tripped up by any single or + double quotes in CJK escape sequences that are within single or double + quoted attribute values. - TA +* Restrict resetting the Kanji code flag on white space to Japanese + (i.e., not also Chinese, Taipai, or Korean). - TA +* Added handling of EPLF lines (with local time) for the FTP gateway. - + D. J. Bernstein (djb@koobera.math.uic.edu) +08-08-96 +* Added code for handling captured OBJECT content with the SHAPES + attribute equivalently to our handling of FIG, and with USEMAP and/or + ISMAP content equivalently to our handling of IMG. +* Added code for capturing potentially nested container elements that + require pre-processing, e.g., OBJECT, and for passing the processed + markup back to the SGML parser to be inserted within the ongoing HTML + stream. +* Added CHECK_EAGAIN Makefile definition for non-SVR4 Unix flavors which + might need it for socket connect() and select() calls. - FM +* Tweaks of keyboard input with slang when LYCursesON is FALSE. - FM +08-06-96 +* Terminate and start a new Accept: header line if the current one will + exceed 1 KB (shouldn't be necessary, but otherwise the long lines cause + an error for WebSitePro and crash Netscape servers, and perhaps have + adversed effects on some other http servers with ill designed code for + content negotiation). - FM +* Give temporary files suffixes matched to the Content-Type for all flavors + of Unix and for VMS, not just for NeXT. - FM +* Tweak of Location: header parsing in HTTP.c (trim all lead spaces). - FM +08-05-96 +* More help and documentation updates. - FM +08-04-96 +* Updated the online help files. - FM +08-03-96 +* Mods of "user (A)gent" 'o'ption handling. Also added a "useragent" + -restriction, included in the defaults for anonymous accounts. See + the "Lynx options menu" section of the "Lynx Users Guide" via the + online 'h'elp for more information. - FM +* Tweaks of messaging for unsupported URLs. - FM +* Tweaks of interrupt handling on VMS. - FM +08-02-96 +* Added handling of Refresh in META tags. The URL is presented as a link + pointed to by a "REFRESH(n sec):" label, where "n" is the seconds + parameter from the META tag, and you must activate it yourself, which + should enable people using Lynx via a braille interface to examine + the initial document before it is refreshed. The META format is: + <META HTTP-EQUIV=refresh CONTENT="n; URL=url"> where "n" can be "0" or + a positive integer, and the "; URL=url" field is optional, defaulting + to the document's own address. Netscape's docs say that "url" should + be a complete URL, but their client doesn't require it, and so it's + users don't reliably use complete URLs. Lynx therefore resolves "url" + versus the document's own address if it is not complete. - FM +08-01-96 +* Added handling of ENCTYPE="text/plain" for FORMs with a mailto ACTION. + The name=value pairs are not hex escaped, and physical newlines instead + of '&' separate the pairs, so that the content is readable directly. - FM +* Added SUBJECT attribute as synonym for TITLE in FORMs (Some clients + are using it instead of TITLE for mailto ACTIONs, ugh!). - FM +* Tweaks of DEL, S, STRIKE, and INS handling. - FM +* Handle any newline characters in quoted INPUT values. - FM +* Added news-ncurses and news-slang Makefile targets, and tweaks of headers + for sony_news. - Makoto MATSUSHITA (matusita@ics.es.osaka-u.ac.jp) +07-30-96 +* Finished and incorporated lynx_url_support.html in the online help, + and updated lynx_help_main.html. - FM +* Tweaks of ID attribute handling. - FM +* Tweaks of the gopher gateway. - FM +* Updated IBMPC-charsets.announce. - MB +07-26-96 +* Set the default anonymous account restrictions if Lynx is invoked in + the account pointed to by ANONYMOUS_USER, or with the -anonymous switch, + before processing any additional command line restrictions, so that any + greater restrictions will not drop back to the compilation defaults. + Note that the full set of -validate restrictions always are enforced for + that switch, i.e., no matter what other switches or compilation options + are used, and whether or not the account is anonymous. - FM +* Implemented handling of the ANONYMOUS_USER definition on VMS (equivalently + to it's implementation on Unix). - FM +* Tweaks of mailto URL handling and setting of the default subject via + TITLE attributes. - FM +* Tweak of the news gateway's handling of the author (From:) field. - FM +07-25-96 +* If a server returns redirection without a complete URL indicated, resolve + it relative to the original request instead of issuing an error message + (this is incorrect behavior, but that's another trashed standard, and + Lynx may as well handle the situation as standard-less clients do). - FM +* Move the NO_JUMPFILE and JUMP_PROMPT definitions to LYMessages_en.h - FM +* Added code for selective disabling of goto by scheme in anonymous accounts, + along lines of patch from Doug Lawson (dlawson@epfl2.epflbalto.org). - FM +* Ignore any viewer mappings for text/html or text/plain in mailcap + files. - FM +07-22-96 +* Updated ptx target and added ptx-slang. - Alan Coopersmith + (alanc@CSUA.Berkeley.EDU) +* Added all the new elements and attributes from the July 12 HTML 3.2/Cougar + DTD, and implemented the new IMG TITLE attribute for use with USEMAP. +* Added a -startfile_ok switch for allowing a non-http startfile or homepage + with -validate, and restored the behavior of not allowing *any* non-http + URLs by default. +07-19-96 +* Treat PLAIN and TYPE="plain" as equivalent in UL tags. - FM +* Fixed the mispositioning of thinsp in HTMLDTD.c. - FM +07-18-96 +* Moved the statusline prompt, message, and warning string definitions + out of userdefs.h into an LYMessages_en.h header. See the comments + in userdefs.h and LYMessages_en.h for more information. - FM +* Removed the -lc from the LIBS= list of the snake3 and snake3-slang + targets, added a description of the HP/UX 10.10 select() problems + and reported (but not yet satisfactory) workarounds in the PROBLEMS + file, and a note in the Makefile to read the PROBLEMS file. - FM +07-17-96 +* Numerous typecasts added for optimized compilations. - FM +* Tweaks for ISC. - WS +* Changed make to $(MAKE) and -g to -O for Unix targets (may need + tweaking for some flavors 8-). - FM +* Added news target for SONY NEWS-OS 4.2.1R based on patch from + Kazuya 'Sharl' Masuda (masuda@sp.hudson.co.jp) and TA. - FM +* Fixed typo in LYList.c from yesterday's mods. - FM +07-16-96 +* Plugged memory leaks associated with temporary file names. - FM +* Finally figured out what was creating orphan child anchors, and plugged + that memory leak in HTAnchor_delete(). - FM +* Replace <sys/select.h> with <sys/timeb.h> for SCO in tcp.h. - BL +* Mods to avoid warning about redefinition of signal when building on + VMS with old versions of SOCKETSHR (irrelevant, but might worry + people who don't know that the warning can be ignored). - FM +07-15-96 +* Plugged various memory leaks in FORM handling code. - FM +07-13-96 +* Add the startfile, and homepage if different, to the 'g'oto recall + buffer so that they are available for editing in addition to any + overtly entered 'g'oto URLs. - FM +* Changed TRUSTED_URL to ALWAYS_TRUSTED_EXEC for clarity, and plugged + memory leaks and some security holes in that code. - FM +* Fixed typo in code for handling Z compressed files. - FM +07-12-96 +* Added handling of   ( ), and handling of   as  , +   as  , – as – or &endash;, — as — or + &emdash;, and ™ as ™ (treated as ® ®), based on the + Cougar DTD. - FM +* Increased the line buffer size in HTLoadHTTP() and limited the deflt string + length in HTPrompt() to avoid possibilities of buffer overruns. - FM +07-11-96 +* Block access to file: URLs via network served files or bookmarks in + addition to 'g'oto entries when -restrictions=file_url is set (one of + the default restrictions for -anonymous). - FM +* Extended compressed file handling to the ftp gateway and local files. + If you ACTIVATE the link instead of overtly invoking a 'd'ownload, and + the path with the gz or Z stripped maps to a displayable Content-Type or + one for which you have a viewer or helper app, the file will be treated + as if it had a Content-Encoding: header indicating the compression (i.e., + uncompressed and displayed or passed to the viewer or helper app). - FM +* Mods to send http servers an Accept-Encoding: header indicating gzip and + compress, and to block inclusion of our new, internal www/compressed MIME + type in the Accept: header list. - FM +* Changed the names of the lex_buffer and lex_lines globals to HTlex_buffer + and HTlex_lines in case name conflicts are causing segmentation faults on + linux for long usernames in authorization requests, and changed all + malloc()'s to calloc()'s in that code in case there's an initialization + glitch I don't yet see. - FM +07-09-96 +* Use the username and password of an -auth= command line argument only + for the first realm that requests authorization, so they don't preclude + access to other realms later in any interactive session that might have + a different username and/or password, and handle inclusion of only a + username or only a password in the -auth= argument. - FM +* Tweaks of memory leak plugs in authorization handling functions (hopefully + now avoiding segmentation faults on linux 8-). - FM +* Include -lc in the first position of the LIBS= list for snake3 targets. + - Donald S. Teiser <dsteis01@homer.louisville.edu) +* Enhancements of Makefile. - LWV +07-07-96 +* Tweaks of code for uncompressing on the fly. Will now force a download + offer without uncompressing if there is no presentation mapping for the + Content-Type. - FM +* Retain blank lines within TEXTAREA content (but not trailing blanks). - DT +07-07-96 +* Added functions for uncompressing and handling documents which have + Content-Encoding headers that indicate "x-gzip", "gzip", "x-compress", + or "compress" (instead of forcing a download offer). The files are + not uncompressed if they were fetched via the 'd'ownload command. + Note, however, that if you activate a link for a compressed image or + other binary file, and don't have a viewer or helper app mapped for it, + it will already have been uncompressed before a D)ownload or C)ancel + offer can be made, so use the 'd'ownload command directly if it is + your intention to download such files. Note also that on VMS "gzip -d" + is used for both gz and Z uncompression. See the INSTALLATION file for + info on getting the VMS port of gzip. - FM +07-06-96 +* Allow any startfile and homepage in -validate mode even if they are not + http URLs. - FM +* Made all the 'o'ptions menu statusline prompts and informational messages + strings that can be defined in userdefs.h for different languages. - FM +* Mods to send one Accept header as a comma-separated list instead of a + series of individual Accept header statements. - FM +07-05-96 +* Added NO_FILE_REFERER configuration symbol and -nofilereferer switch + for disabling transmissions of Referer headers for any file URLs (is + a subset of what NO_REFERER_HEADER and -noreferer disable). - FM +* Tweaks to facilitate additions of security-related patches. - FM +07-04-96 +* Added NEWS_CHUNK_SIZE and NEWS_MAX_CHUNK configuration symbols and + -newschunksize and -newsmaxchunk switches for regulating the chunking + of news article listings. See comments in lynx.cfg for explanation. - FM +07-02-96 +* Tweaks of URL_DOMAIN_PREFIXES and URL_DOMAIN_SUFFIXES handling (was + doing double scheme prefixing under some circumstances). - FM +* Fixed problem of potential crashes with bad HTML which lacks any + OPTION tags in SELECT containers (Yes, HTML that bad is really out + there! 8-). - FM +* Fixed problem of potential infinite loop in HText_endAppend() for documents + that contain nothing but SCRIPTs and empty OBJECT containers (as in the + Microsoft ActiveX demos). -FM +07-01-96 +* Added circular recall buffer for paths used as the second argument in + 'd'ownload and 'p'rint menu commands. Use the up- and down-arrow keys + to access then at the statusline prompt, equivalently to the recalls for + previous 'g'oto URLs, 'j'ump shortcuts, and ISINDEX or WHEREIS search + queries. - FM +* Modified the LYMail.c functions to work as intended with both curses + and slang (through v0.9-33) on both Unix and VMS. - FM +06-30-96 +* Changed yesterday's symbols to URL_DOMAIN_PREFIXES and URL_DOMAIN_SUFFIXES + and added code to guess the scheme based on the first field of the domain + name (e.g., gopher.wfbr.edu will become gopher://gopher.wfbr.edu instead + an http://host URL). Note also that a partial host string can contain a + dot within it and still be tested with prefixes and suffixes if the DNS + lookup fails with the host string as entered (e.g., cc.ukans will become + http://www.cc.ukans.edu), and only dots at the end or beginning of the + partial host string will block prepending or appending, respectively, of + items from the prefix or suffix lists (e.g., ftp.foo. will block use of + items from the prefix list, but permit tests from the suffix list, and + will become ftp://ftp.foo.dom if the ftp.foo.dom lookup succeeds). - FM +06-29-96 +* Added HTTP_DOMAIN_PREFIXES and HTTP_DOMAIN_SUFFIXES in userdefs.h and + lynx.cfg for defining lists and setting the order of domain name prefixes + and suffixes to use when creating http:// URLs from command line and + 'g'oto arguments which are not already URLs and cannot be opened via a + file://localhost URL (see 05-30-96 entry). - FM +06-28-96 +* Tweaks of MIME header handling. - FM +06-27-96 +* Do not send a referer header for links obtained from the history list, + bookmark file, or jumps file. - FM +* Made sorts by name case-sensitive in ftp and file listings. - FM +* Added osf-slang make target. - FM +* Enable ^C (SIGINT) interrupts during spawns on Unix (^C and ^Y interrupts + were already being enabled for VMS ). - FM +* Fixed glitch in WHEREIS search handling. - Michael Barabanov + (baraban@luz.cs.nmt.edu) +06-26-96 +* Tweaks of ftp gateway for VM/CMS servers based on feedback from PG. - FM +* More tweaks of 'o'ptions menu and DISPLAY handling. - FM +* Tweaks for builds with WIN_TCP on VMS. - FM +06-24-96 +* Modified 'o'ptions menu handling to allow NULLing of strings which were + set at startup. Note that if you NULL (or set) the DISPLAY variable, + Lynx configured itself for X/Motif or not based on whether it was set + (or NULL) at startup, and you need to restart Lynx to really change the + configuration for 'd'ownload forces versus X/Motif viewer spawns. - FM +* More tweaks of language code, to make the HTCJK enum checks more + portable. - FM +06-23-96 +* Set up handling of nested DIV tags with ALIGN attributes (and CENTER, + which is treated as DIV ALIGN="center"). - FM +* Removed INSERT, ALIAS and MH from the DTD, and their associated code + from HTML.c and GridText.c. - FM +06-22-96 +* Tweaks of character set handling. - FM +* Added function for graphic boxing of popups with curses on VMS. - FM +06-21-96 +* Mods to translate CJK escape sequences and take Kanji into account when + handling statusline() messages. That's in effect if a CJK character set + is selected, and regardless of the raw or CJK mode setting, because the + strings are coming from definitions in userdefs.h, not the document that + is being rendered or displayed. - FM +* Added more statusline() string definitions in userdefs.h. - FM +* Ignore a server's Content-Encoding header if it inappropriately indicates + "8bit" or "7bit" (should be indicated a compression scheme). - FM +* Mods to use charset strings as in the 07-Jun-1996 HTTP/1.1 draft, and to + check for those as well as their common synonyms. - FM +* Mods to revive clearok() functionality with the slang 0.99-33 library + (need it for Kanji handling and for VMS), and to deal with the definition + conflicts for the (poorly added) TRUE and FALSE definitions in the new + slang library's SLcurses.h. - FM +06-20-96 +* Added handling of the SFS file system on VM ftp servers, tested on + ftp://ubvm.cc.buffalo.edu/ (be sure to escape the colons if you use SFS + paths, e.g., ftp://ubvm.cc.buffalo.edu/vmsysu%3alistserv.webshare) - FM +* More memory management enhancements and leak plugs. - FM +* Added -DUNIX and -DSCO to the sco and sco5 libwww targets. - BL +06-17-96 +* Added handling of ­, ­, and 8-bit 173 for ISO-Latin-1 documents, + as a soft hyphen for all of the character sets. - FM +* Polished up and massively annotated the new character set handling + code. - FM +* Made all the dummy libwww headers in WWW/Library/Implementation + compatible with the new, actually used, headers in /src. - FM +* Fixed some bad ifdef-ing for statusline string definitions which + were added to userdefs.h. - FM +06-15-96 +* Added many more userdefs.h definitions for statusline() and HTAlert() + messages. - FM +* Tweaks of ALT string handling when they are used as forced link names + for USEMAP, AREA, IMG, EMBED or APPLET sources. - FM +* Oops, hadn't put the new HTML.h in the zip. - FM +* Fixed casing typo for HTCJK.h inclusion in HTMIME.c. - LWV +06-14-96 +* Updated the help files, lynx.man and lynx.hlp concerning the character + set handling. - FM +* Changed the -jpn switch to a generic -raw switch, and the LYK_JPN_TOGGLE + ('@') to a generic LYK_RAW_TOGGLE. The toggling also can be done via + the 'o'ptions menu, in conjunction with selecting character sets. See + the comments about CHARACTER_SET in userdefs.h and lynx.cfg for more + information. The toggle determines whether raw 8-bit characters in the + document are assumed to be ISO-8859-1, and therefore translated for the + non-"ISO Latin 1" character sets based on their LYCharSets.c arrays, or + are assumed to match the character set (e.g, 8-bit ISO-8859-2 when the + "ISO Latin 2" set is selected, or Kanji when a CJK set is selected) and + therefore processed raw. Use raw or CJK mode when you know the charset + of the document is a match to your selected character set, but no header + or suffix has indicated that the charset is not ISO-8859-1. Be careful + about this when "Other ISO Latin" is selected, since the document could + be, e.g., ISO-8859-3, but you are using, e.g., ISO-8859-5. - FM +* Added "Other ISO Latin", "Chinese", "Japanese (EUC)", "Japanese (SJIS)", + "Korean", and "Taipei (Big5)", character sets, which presently translate + 8-bit ISO-8859-1 named and numeric entities to 7-bit approximations, and + added a default "CHARACTER_SET" definition in userdefs.h, complementary + to that in lynx.cfg. - FM +* Worked in the expanded CJK (Chinese, Japanese, Korean) escape sequence and + Kanji handling from Takuya ASADA's June 11, 1996 Lynx2-5CJK (available in + ftp://ftp.three-a.co.jp/pub/www/lynx). - FM +06-11-96 +* Tweak of the ftp gateway to handle Reflection Unix emulation servers. - FM +* Made lynx_version_putenv_command a global so we can free it at exit + via free_lynx_globals() in LYMain.c. - FM +06-10-96 +* Convert a 0xFFFF value from slang in LYgetch() to 7 (^G) to cancel + whatever called it, instead of exiting on error. - FM +* Tweaks of Makefile to use symbolic, $(include) and $(lib) paths with + ncurses for convex, NeXT and sun4, and for SOCKSLIB. - LWV +* Tweaks of mail editor handling based on patch from Arne Riiber + (riiber@systek.no). - FM +06-09-96 +* Had overdone it plugging memory leaks and was freeing the proxy, news + server, and lynx version variables too soon. - FM +06-07-96 +* Moved the Kanji handling variables into HText structure elements to make + the GridText.c functions reentrant for them, and added code for regulating + them via charset parameters in server headers or META tags. The recognized + parameters are EUC-JP, Shift-JIS, ISO-2022-JP, ISO-2022-JP-2, and EUC-KR. + E.g., a META with: + HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=Shift-JIS" + will set up handling of the document as Shift-JIS. - FM +* Made handling of Kanji more reliable when SJIS is the default, based + on the strategy in Takuya ASADA's Japanized Lynx2-4-2. - FM +* K&Rized the Ichikawa ISO-2022-JP MIME header handling functions and added + them to HTMIME.c, together with Takuya ASADA's (asada@three-a.co.jp) + function for guessing whether an escape has been lost and filling it in, + and use them for checking news headers. - FM +* Retry DCL spawns without the TRUSTED flag if it was included and we + got back an INVARG status. - Robert C. Gray (gray@cyberodyssey.com) +06-06-96 +* Plugged lots of memory leaks. - FM +* Handle colons in code for expanding host names and prepending http:// + (e.g., wfbr:8002 will become http://www.wfbr.edu:8002/). - FM +* More tweaks of character conversions. - FM +* Block crashes if illegal markup such as Anchors are present in the + OPTION strings for SELECT. - FM +06-04-96 +* Mods of entity and end tag handling in SGML.c and LYCharUtils.c. - FM +* Tweaks of make target for sun4-slang. - NHE +06-03-96 +* More tweaks of the ftp gateway. - FM +* More anti-crash protections for bad HTML. - FM +* Tweaks of LYCharUtils.c and SGML.c. - KW +* Enclose the username for rlogin URLs in double-quotes on VMS to preserve + mixed casing if present. - Robert C. Gray (gray@cyberodyssey.com) +06-02-96 +* Made DEFAULT_CACHE_SIZE and DEFAULT_VIRTUAL_MEMORY_SIZE configurable via + lynx.cfg. - FM +* Added comments in HTFTP.c to make more clear some of the counterintuitive + things being done, and why. - FM +* Oops, had left my ISSPACE() debugging macro in HTFTP.c yesterday. Is + now back to isspace(). - FM +06-01-96 +* Added support for ;type=I (or A or D) to specify Image or ASCII transfer + modes, or a Directory, in ftp URLs. - FM +* Added support for VM/CMS ftp servers. Note that 'd'ownloaded text files + will have CRLF as line terminators, due to their use of ASCII records + (tested on ftp://pucc.princeton.edu/anonymou.376). - FM +* Added support for use of a tilde on Unix ftp servers to indicate that you + want a listing of the user's login directory instead of the root (i.e., + ftp://user@host/~ or ftp://user@host/~username will cause Lynx to attempt + a listing of the translated ~ or ~username). Paths can be appended (e.g., + ftp://user@host/~/subdirectory). This should not be used with anonymous + ftp, or in public documents. It yields the behavior on Unix or Unix-like + ftp servers which should occur without the tilde, based on RFC 1738. Note + that the valid behavior involving use of %2f is implemented for VMS (see + the 12-20-95 entry, below), but the behavior for Unix and Unix-like ftp + servers emulates Lynx's Unix DIRED_SUPPORT. - FM +* Mods of CSO/PH gateway to deal with discontinuous field name tokens + (e.g., "NYU fax" instead of "NYU_fax"). - FM +* More fixes for the putenv_command pointer in LYMain.c. - CC +* Add curly braces to the current hack for mininizing reversals of + trace messages with slang. - KW +05-30-96 +* Modified the http:// prepending code to try expanded host names if the + the first (or only) element does not contain a dot and is not a known + host name. Will first try it as www.host.com, then www.host.edu, then + www.host.net, then www.host.org, e.g., wfbr/dir/lynx will become an + http://www.wfbr.edu/dir/lynx URL. - FM +* Added handling of MSDOS_SERVER ftp server type (tested on ftp.hayes.com) + and corrected WINDOWS_NT_SERVER handling (tested on ftp.boca.org). - FM +* Reset any modified, non-HT-LEFT styles in HTML_free() if they were not + reset in HTML_end_element() due to missing end tags. - FM +* Initialize the putenv_command pointer in LYMain.c. - Christophe Colle + (colle@krtkg1.rug.ac.be) +* Include LYLocal.h in LYCgi.c. - Carl Hansen (hansen@best.com) +05-28-96 +* Made all mainloop() statusline() message strings definitions in userdefs.h + for easier modification to other languages (we'll move them to a catalog + someday 8-). - FM +* Added string definitions in userdefs.h for statusline messages identifying + active or DISABLED radio buttons. - FM +* More tweaks of character conversions. Note that numeric entities with + values greater than 255 are displayed as text, until we are able to + handle them as Unicode. - FM +* Implemented ID handling for BDO. - FM +05-27-96 +* Added nested handling of Q, so that it alternates between double-quotes + and single-quotes, with directionality of start and end single-quotes + (should someday check the LANG and DIR attributes, and character set, + to use other quoting conventions if appropriate). - FM +* Use [DEL: ... :DEL] labeling to indicate DEL content, and [INS: ... :INS] + labeling to indicate INS, S, and STRIKE content. - FM +* Added ID handling for ABBREV, ACRONYM, AU, AUTHOR, BIG, DEL, INS, Q, S, + SMALL, SUB, SUP and SPAN. - FM +* Added code to clear the screen of any trace messages directed to the + screen, once the full page has been created. - FM +* Added code to minimize slang's casting of trace messages as reverse when + directed to the screen instead of a file. - FM +05-26-96 +* More tweaks of character conversions. - FM +* Added submit_enctype elements to the forms structures as will be needed to + implement INPUTS with TYPE="file" (someday 8-), and set disabled for FORM + fields if the ENCTYPE is multipart/form-data, until we can handle that + (someday 8-), so the user won't fill out the FORM pointlessly. - FM +* Made the third argument of SLang_init_tty() 1 so that '\n' will be treated + as CRLF when trace messages are sent to the screen instead of to a file. + Might cause problems with the slang screen management functions, but + doesn't seem to according to KW. - FM +05-25-96 +* Mods to pass 8-bit control characters entered via the line editor. They + should be assumed to be valid if the user entered them, and could indeed + be valid for Japanese and Russian. - FM +* Check for a NULL return value from initscr() on Unix. - Geert Jan de Groot + (GeertJan.deGroot@ripe.net) +* Tweaks of character conversions, and of 8-bit character handling with + slang. - Klaus Weide (kweide@tezcat.com) +* Added TRUSTED_URL for specifying lynxexec and lynxprog URLs which always + are permitted, based on patches from David Drum (david@more.net). - FM +05-21-96 +* Made the LOCAL_DOMAIN symbol configurable via lynx.cfg. - FM +* Added descriptions of the quality (q=) and maxbytes (mxb=) parameters + in the sample mailcap file. - FM +* Added a maxbytes element to the libwww presentation and converter + structures, and code for specifying a maximum for mailcap entries via + a semi-colon-separated mxb=value field, where "value" is a positive + integer (e.g., ; mxb=1000000). The default is 0, meaning no maximum. + If the value exceeds 0, a maxbytes parameter will be appended in the + Accept: header for the Content-Type. - FM +05-20-96 +* Added code for specifying a quality parameter for mailcap entries via + a semi-colon-separated q=value field, where "value" is a floating point + number (e.g., ; q=0.002), and for appending the quality parameters in + Accept: headers if the values are less than 1.0. - FM +* Treat screen width as 80 for the startup page when doing traversals with + a slang-build Lynx to prevent a crash. - FM +05-19-96 +* Mods in HTML.c to make resolving of local file URLs more efficient. - FM +* Tweaks of Makefile for slang. - Ed Doolittle (dolittle@math.toronto.edu) +05-18-96 +* Added FRAME elements and attributes to the DTD, and code for creating + links to the SRCs. - FM +* Added numerous sanity checks for valid but inappropriate combinations + of attributes based on the HTML 3.2 DTD. +05-17-96 +* Added support for TYPE and VALUE attributes of LIs in OLs. TYPEs + are equivalent to those for OL, and VALUE is equivalent to START + or SEQNUM for OL. See the 11-28-95, 10-17-95, 09-19-95 and 09-04-95 + entries in this file. If a TYPE is changed via an LI, the change + persists for subsequent LIs of that OL. The VALUE set for an LI + similarly increments for subsequent LIs in that OL. - FM +05-16-96 +* Made SGML_character() in SGML.c fully reentrant. - FM +* Set up capturing of marked sections, and DOCTYPE, ELEMENT, ATTLIST and + ENTITY declarations in SGML.c. Lynx doesn't do anything with them yet, + besides reporting them in trace mode, but they at least won't create + garbage in the display if they start being used for the "next generation" + of clients. - FM +* Set up base code for CSIs (Client Side Includes, homologous to SSIs). + See the comments for LYDoCSI() in LYUtils.c. It should be moved to a + separate module if someone wants to work on CSIs seriously. LYDoCSI() + is called from SGML.c if the document was obtained via a file URL on + the local host and has comments that begin with "!--#". - FM +05-15-96 +* Add a MIME charset parameter to POST Content-Type headers if it's not + ISO-8859-1 or US-ASCII and the server included the parameter when it + sent the form (but don't do it simply on the basis of the user's current + character set, because if the server didn't include the parameter, it's + CGI script probably won't parse the client header either, and will return + an error instead of processing the form submission). - FM +05-14-96 +* Tweaks for Unixware and addition of a unixware-slang Makefile target based + on patches from Thanh Ma (tma@encore.com). - FM +* Tweaks for SCO and addition of an sco5 Makefile target based on patches + from Bela Lubkin (filbo@armory.com). - FM +* Include ;q=0.001 for the wildcard (*/*) Accept header. - FM +05-13-96 +* Added support for a host field in news URLs, analogous to that for nntp + URLs. Though illegal according to the current RFCs, discussions with a + W3C member about this Netscapism indicate that Lynx may as well support + it now, rather than continue failing when it is encountered. - FM +05-12-96 +* Added an explicit GetYX definition for slang in LYForms.c. - FM +05-11-96 +* Eliminated the NCURSESINCDIR compilation symbol and added NCURSESHEADER, + so the default now is to seek ncurses/curses.h and -DNCURSESHEADER invokes + a seek for the (now obsolete 8-) ncurses.h. - FM +* Added an explicit GetYX definition for slang in LYStrings.c (now avoids + reference to stdscr). - FM +* Mods in tcp.h for TCPWARE builds on VMS with DECC. - FM +05-08-96 +* Fixed typo in Makefile entry for linux. - LWV +05-07-96 +* Added LYPassHighCTRL boolean for passing normally illegal 8-bit control + characters, and set it TRUE when the KOI8-R character set is selected + (note that they also are passed when Japanese character support is + toggled ON). - FM +05-06-96 +* Mods in SGML.c to handle "<URL:" as text instead of an unknown tag. - FM +05-05-96 +* Added typecasts of the third arguments for the getsockname() and + accept() calls in HTFTP.c to void pointers, to avoid conflicts with + their declarations as int versus unsigned int across platforms and + flavors. - FM +* Renamed the for-VMS opendir(), readdir() and closedir() to HTVMSopendir(), + HTVMSreaddir() and HTVMSclosedir(), and the for-UCX ioctl() to HTioctl(), + to avoid possible conflicts with their additions to newer versions of + VMS and UCX. - FM +05-04-96 +* Fixed typo which was placing a space instead of a slash between the + User-Agent name and version. - Tim Rowley (tor@cs.brown.edu) + +--- STARTING 2.5FM --- +--- Rename of Lynx2-4-FM and release as Lynx2-5 (02-May-1996) --- + (see CHANGES2-5, CHANGES2-4 and CHANGES2-3) +============================================================================== |
