--- Rename of Lynx2-4-FM and release as Lynx2-5 (02-May-1996) --- ============================================================================== 05-02-96 ---- Release of Lynx2-5 ---- * Modified documentation, help, and example files based on feedback for yesterday's Lynx2-5 pre-release. - FM * Include ";q=0.001" whenever "iso8859-1" or "us-ascii" are autoappended to Accept-charset headers. - FM * Added SITE_LIBS symbol in Makefile for convenient linking to any site-specific libraries associated with any site-specific patches. - FM * Fixed an unsigned char typecast in GridText.c - FM * Eliminated statusline and TRACE warnings about possibly strange formatting when TABLEs are in a document. - FM 05-01-96 * Renamed Lynx2-4-FM for pre-release as Lynx2-5 04-30-96 * Modified the fatal error messages such that they direct the user to the local system administrator to confirm a bug before reporting it to lynx-dev, and started updated the help and about files for the switch to lynx-dev@sig.net as the primary list server. - FM 04-28-96 * Made use of ordered versus unordered lists and inclusion of article dates in listings for news groups compilation and configuration options in userdefs.h and lynx.cfg. - FM 04-27-96 * Added -realm switch for restricting URLs to the realm of the startfile. The bookmark and jumps files are always considered as part of the realm. Any execution links or form ACTIONs are permitted if obtained from documents in the realm, but any switches that restrict bookmark operations will still apply. For example, -book -realm will use the bookmark file as the startfile, and restrict URLs to files in the user's account. Adding -restrictions=bookmark_exec will block execution links in the bookmark file, but not in other files within the realm (i.e., in the user's account). If the startfile is an http URL, the realm will be equivalent to that in http authorization procedures. Can be used with -traversal for restricting the traversal to documents within the starting realm for an http server. - FM * Fixed bug in form structure which could cause POST to be treated as GET. - FM 04-25-96 * Added code to send Host: headers as described in the 23-Apr-96 HTTP/1.1 draft. - FM 04-23-96 * Modified HTMIME.c to pass documents with an ISO-8859-3 through -9, EUC-KR, or ISO-2022-KR charset specified in the Content-Type header, to set the flag for not doing 8-bit reverse translations, and to issue a statusline message about the charset instead of forcing a download offer. Will have garbage in the displays of 8-bit characters if one doesn't have the corresponding charset installed for the terminal, but no harm should be done, and those who do can get the files displayed instead of just being up the creek without a paddle. Korean escape sequences will still be trashed, since be have no translation functions as for Japanese, and we still force a download offer if there is a mismatch for the supported character sets, so the user can cancel and then modify the terminal setup and charset choice appropriately. - FM * Increased the maximum number of attributes for tags (was too small for OBJECT), updated the DTD for SCRIPT, and added the STYLE attribute for all tags which presently, or might someday, accept it. - FM 04-21-96 * Modified the news gateway to use an ordered list with the numbers and dates of the articles indicated in newsgroup listings. - FM * Fixed the checking and passing of the mailto argument in LYMainLoop.c to mailmsg() in LYMail.c. - FM 04-20-96 * Fixed bugs in parsing of nntp and snews partial HREFs, and in the parsing of NNTP message headers for creation of mailto and newspost or newsrepy links. - FM 04-19-96 * Added OBJECT and BODYTEXT to the DTD, based on the 12-Apr-96 W3C draft. The code for INSERT is still there, and should be remove if OBJECT becomes a stable replacement. Code to handle data URLs for OBJECTs not yet attempted. - FM * More tweaks for Japanese character handling. - FM 04-18-96 * If LINKS_ARE_NUMBERED is on, include the list of references in the outputs of 'p'rint menu options, analogously to the output with -dump. - FM 04-14-96 * Mods to report the content of SCRIPT, STYLE and ALIAS blocks in trace mode. - FM * Made ¨, ¯ and ™ synonyms for ¨, &hibar; and ®, respectively. - FM * Fixed typo in second line link highlighting code for slang. - ES 04-13-96 * More tweaks of Japanese character handling. - FM * Reinitialize timeout values after select() calls in LYUtils.c. - ES 04-12-96 * More tweaks of Japanese character handling. - FM * Tweak of target line and link setting when toggling to image_links mode in LYMainLoop.c. - FM * Tweaks of circular buffer handling based on analyses from Mike Castle (mcastle@umr.edu) and Bryan T. Vold (btv@ldl.HealthPartners.COM). - FM * Fixed typo for NeXT in tcp.h, based on feedback from LWV - FM * Reinitialize timeout values after select() calls in HTTCP.c. - Erik Sundkvist (ess@lysator.liu.se) 04-11-96 * More tweaks of Japanese character handling. - FM * Added code for handling charset mappings for file and ftp URLs. - FM You can set the mappings via lynx.cfg (or mime.types), e.g.: SUFFIX:.html8R:text/html; charset=KOI8-R SUFFIX:.txt8R:text/plain; charset=KOI8-R * Tweak of charset handling in HTMIME.c - FM 04-09-96 * Modified news gateway to handle split header lines. - FM * Tweaks of authorization header handling to make failures due to bad headers from the http server clear to the Lynx user. - FM 04-08-96 * Yet more tweaks of memory management. - FM 04-07-96 * Tweaks for handling Japanese received via gateways. - FM 04-06-96 * More memory management tweaks. - FM 04-05-96 * Updated lynx.man, lynx.hlp and the online help files. - FM * Tweaks of INPUT, TEXTAREA and SELECT popup OPTION handling when Japanese character translations are on. - FM 04-04-96 * Created new zip. Yesterday's appears to have been bad. - FM 04-03-96 * More optimizations and bug fixes based on patches from JED. - FM * More mods for handling keyboard input via SLANG library functions, based on patches from JED. Note that the code for IGNORE_CTRL_C has been bypassed in those mods, as they presently stand. - FM 04-02-96 * Added "first pass" handling of P end tags. - FM * Mods of HTCheckForInterrupt() for SLANG, based on patches from JED. Note that the for-SLANG code is not taking possible SOCKSification of Lynx into account. - FM * Use 3 for ^C instead of 7 for ^G as the argument for the slang abort key in calls to SLang_init_tty(). - JED * Tweaks of make for clix. - AM 03-31-96 * More tweaks of memory management. - FM 03-30-96 * Added support for Japanese translations of text/plain in addition to text/html documents, and for ALTs and form fields (see 03-26-96 mods). Needs checking. Also added an LYK_JPN_TOGGLE, mapped to '@' by default, for toggling JAPANESE mode ON and OFF, and code to indicate the situation in the 'o'ptions menu. - FM * Added make for ultrix-slang and decstation-slang, and tweaks of LYCgi.c for ultrix. - Alvian Tam (atm@newt.phys.unsw.edu.au) * Found and fixed some typos in yesterday's mods. - FM 03-29-96 * Added build-slang.com for building Lynx with the SLANG library instead of curses on VMS. - FM * Mod to treat an EOF with errno of EINTR when GetChar() is defined as getchar() in LYgetch() as due to a Ctrl-Z suspend, and invoke another character fetch instead of exit on error. Based on patch from Gregory Neil Shapiro (gshapiro@WPI.EDU). - FM * Numerous optimizations and bug fixes based on patches from JED. - FM 03-28-96 * More tweaks of SLANG support. - FM * Yet more tweaks of the HTList functions and macros, and their associated memory management. - FM 03-27-96 * Fixed bug which could cause a crash if links are numbered and you activate a link via a number when there are no links on the currently displayed page. - FM * Tweaks of Content-Encoding header handling, and more detailed messages about it in trace mode. - FM 03-26-96 * Added code in HTMIME.c for taking into account Content-Encoding headers, so that compressed text/html or text/plain files are not displayed inappropriately based on their Content-Type. - FM * Added "first pass" support for Japanese character translations, based on patches for Lynx2-4-1 by Takuya Asada (asada@icsd6.tj.chiba-u.ac.jp). Is to be checked out by Nelson Henry Eric (nelsonhe@ews07.nara.kindai.ac.jp) because I have no way to check it here. Translations can be made the default behavior by setting JAPANESE to TRUE in userdefs.h and/or lynx.cfg. The default can be toggled via a "-jpn" command line switch. If made TRUE by any means, the value of KANJI_CODE set in userdefs.h and or lynx.cfg (EUC, SJIS, or NONE) will be applied, and can be changed via "-euc", "-sjis" or "-ascii" command line switches, for setting Kanji code translations to EUC, Shift JIS, or disabling it, respectively. Note that Japanese translations are not yet performed in the line editor (LYgetstr() of LYStrings.c and form_getstr() of LYForms.c), for form field values, or for gateways (let's first see if what I've done so far works right 8-) - FM * Added "LY" prefix for pop(), pop_num() and push() function names to avoid possible conflicts with the ncurses library functions, and fixed continuation line typo in solaris2 make, based on feedback from PN. - FM 03-23-96 * Tweaks of memory management in the CSO/PH gateway. - FM * Tweaks of wait() versus waitpid() handling for NeXT, aix4 and mips, based on feedback from PN. - FM 03-22-96 * Tweaks of SLANG support for Unix, and finished up code support for it on VMS (but tested only with OpenVMS/AXP). Haven't yet decided how to add VMS build support for it in the COM and MMS files. Get the SLANG library code from ftp://space.mit.edu/pub/davis and then add USE_SLANG in the DEFINE list and the path to it's headers in the INCLUDE list for the compilation, and [path]slang.olb/lib in the link list immediately before the OPT file. We still need the curses library in the OPT file, because that's not just curses functions on VMS and we're using ones not replaced by the SLANG library (Try it, you'll like it! 8-). - FM * Tweaks for NeXT, based on feedback from Paul Nevai (nevai@ops.mps.ohio-state.edu). - FM 03-20-96 * Tweaks of code for sorting directory listings by date (take into account the 6-month-old time versus year rule on Unix). - FM * Tweaks of memory management for HTList-based buffers (use internal allocations, instead of the libwww macros). - FM * Added solaris2-slang to Makefile, and tweaks of the sun4 makes. - LWV 03-19-96 * Tweak of MAP handling so that the ordered lists are displayed exactly in the order of the resolved AREA tags. 03-18-96 * Added SLANG support (for colorized Lynx) based on patches from JED. The make support is for linux and sun4, but it should be portable to other Unix flavors. I have it working on VMS, but the SLANG interrupt and exit handlers are incompatible with the current ones for VMS in Lynx (and with the VMS debugger), so I haven't yet included SLANG support in build.com or the MMS files. - FM 03-17-96 * Tweaks of 'd'ownload menu handling on returns to it from a DOWNLOADER action. - FM * Added various anti-crash protections and cleaner code from John E. Davis (davis@space.mit.edu) for trimming trailing white space and finding unescaped colons in LYReadCFG.c, and cleaned up and more fully commented the functions and subfunctions in that and the LYMainLoop.c modules. - FM 03-16-96 * Fixed routine which sorts directory listings by date (based on 'o'ptions menu setting) to do it accurately and in reverse chronological order. - FM 03-15-96 * Added code to create links for likely URLs in results returned by the CSO/PH and finger gateways. Try: gopher://ns.bradley.edu:105/2 or: cso://ns.bradley.edu/ and search for David Henderson. Also try: gopher://cegt201.bradley.edu:79/0/w%20davidh or: finger://cegt201.bradley.edu/w/davidh as URL.s - FM * Added LYK_INTERRUPT handling for the CSO/PH and finger gateways, and made their memory management more efficient. - FM * Made the my_spawn() function in LYLocal.c more portable by using waitpid() instead of wait(). - FM * Restored the Lynx2-3 behavior of seeking the current position and link on return from 'e'dit. May be wrong if the file was modified, but it might be in the right ball park, and nothing really bad will happen if it's far off. - FM 03-14-96 * Added -reload switch for instructing Lynx to send "Pragma: no-cache" and "Cache-Control: no-cache" headers when requesting the startfile from an http server (doesn't apply to subsequent fetches, or to non-http startfile URLs). - Peter Ekberg (peda@lysator.liu.se) * Put the correct LYMain.c, which declares no_change_exec_perms, in the zip (second try, hope I really did 8-). - FM 03-13-96 * Yet more tweaks of the CSO/PH gateway. - FM * Yet more tweaks of the finger gateway. - FM 03-12-96 * Made the URL and command buffering in the finger gateway secure from stack modifications, beautified the HTLoadFinger() and response() functions, and added support for the following URL formats for sending a "", "/w", "username", or "/w username" command to the finger server: finger://host finger://@host finger://host/ finger://@host/ finger://host/%2fw finger://@host/w finger://host/w finger://host/w/ finger://host/username[@host] finger://username@host finger://host/username[@host]/ finger://username@host/ finger://host/w/username[@host] finger://username@host/w finger://host/%2fw%20username[@host] finger://host/username[@host]/w * Replaced the _tolower macro in the CSO/PH gateway with TOLOWER. - FM * Tweaks of DIRED_SUPPORT. Added NO_CHANGE_EXECUTE_PERMS compilation symbol and change_exec_perms restrictions switch for restricting changes of the eXecute permissions to directories, and not files, when OK_PERMIT has been set. - Earl Fogel (fogel@duke.usask.ca) & FM * Added make support for Intergraph CLIX (note that some online help files must be edited and renamed to meet this Unix flavor's 14 character file name limit). - Alex Matulich (matuli_a@marlin.navsea.navy.mil) 03-11-96 * Added support for using finger://host/w/username to send "/w username" to finger (port 79) servers. - FM * Tweaks of alignment handling to deal with (illegally) embedded CENTER containers (typically due to omission of an end tag for the first CENTER of the pair; ugh!). - FM 03-10-96 * Added form-based CSO/PH (port 105) gateway. Can be invoked via a cso://host[:port]/ or gopher://host[:port]/2 URL. If the gopher format is used and a query token is appended (?[query]), the old ISINDEX-based gateway will be used. - FM 03-07-96 * Added NO_FROM_HEADER configuration symbol in lynx.cfg, and -nofrom command line switch, for blocking all transmissions of From headers by Lynx. - FM * Added NO_REFERER_HEADER configuration symbol in lynx.cfg, and -noreferer command line switch, for blocking all transmissions of Referer headers by Lynx. - FM * Enhancements of the 'o'ptions menu. - FM 03-06-96 * Restored the Lynx2-3 behavior of seeking the current document position and link on (^R)eloads. Will be wrong if the document is actually a changing script output, or SSI with changes in the sizes of inserts, and any form entries will be lost with no warning about that if no form links are in the currently displayed page (and there may be other glitches I don't remember any more). However, it's correct, and more convenient, most of the time, and nothing really bad will happen if it's wrong. - FM 03-05-96 * Added SAVE_SPACE configuration symbol in lynx.cfg, and LYNX_SAVE_SPACE environment variable (Unix) or logical (VMS) for setting a default path prefix in suggested filenames in Save to Disk operations of the 'p'rint and 'd'ownload menus. If not set, only a filename will be suggested, for saving in the current default directory. See the INSTALLATION file and lynx.cfg for more information. - FM 03-02-96 * If an IMG tag has both ISMAP and USEMAP attributes, create links for both, and use the ALT string, if present, for the USEMAP link. The server-side script might have a content-rich default set up for non-GUI clients, so we may as well be able to try it, and still have our own USEMAP listing available if it's a site unconcerned about text and braille clients, or GUI clients with image loading turned off. - FM * Tweaks of MAP code to maximize efficiency of fetching and processing MAPs from a different document. - FM * Make sure the traversal code doesn't get tripped up by any HREFs which contain newline characters due to misparsing (e.g., because a close-double-quote wasn't present where required, and soft_dquotes wasn't toggled ON, or invalid comments were present, and minimal or historical comment parsing weren't toggled ON). - FM * Renamed LYK_RESUBMIT ('x' or 'X') to LYK_NOCACHE and modified it's code so that it applies to normal links as well as form submit buttons. If used instead of LYK_ACTIVATE, any HText cache from a previous submission or request will be dumped, and the submission or request will be made with the "Pragma: no-cache" and "Cache-Control: no-cache" headers included, to ensure that a proxy/cache server also will not return a cached copy (assuming it respects either of those headers). - FM 03-01-96 * Converted the client-side image MAP code to a protocol which returns a stream, rather than using a temporary file. This allows saving the link as a bookmark, for fetching the MAP and creating a listing without need to fetch and render the original document. Also enabled direct downloading of the MAP listing. - FM 02-29-96 * Added handling of client-side image MAPs. If both USEMAP and ISMAP attributes are present, the client-side MAP is used instead of the the server-side script. The MAPs can be in the same or different documents. The HREFs of the AREA tags are presented as a list, with their ALTs (if present, otherwise their HREFs) as the link names in the list. Added a TITLE attribute for MAPs, which will be ignored by GUI clients, but if present will be used by Lynx as an H1 for the list (MAP NAME="welcomemap" TITLE="Welcome Map"). Otherwise, the IMG's ALT (if present, otherwise "[USEMAP]") will be used as an H1 in the list. The MAP's resolved URL also is shown in the list, since the URL for the list is a temporary file. - FM 02-25-96 * Added a MINIMAL_COMMENTS configuration symbol, which if set TRUE in lynx.cfg will emulate the Netscape v2.0 comment parsing bug of seeking only a '-->' terminator, and not interpreting '--' pairs as serial comments within the overall comment element. The compilation default is FALSE, but we'll set it TRUE in lynx.cfg until Netscape gets its comment parsing right, and "decorative" dashes in comment elements cease to be so common in "Enhance for Netscape" pages. Also added a '-minimal' command line switch for toggling the Minimal or Valid configuration setting, and an LYK_MINIMAL command key toggle (mapped by default to backquote). Note that setting Historical comments on will override the Minimal or Valid setting (i.e., any '>' will be treated as the terminator of a comment element). A statusline message indicates whether Historical, Minimal or Valid comment parsing has gone into effect when the LYK_MINIMAL or LYK_HISTORICAL command key toggles are used (i.e., those two toggles in effect are a "troggle"). - FM 02-22-96 * Tweak of HTList manipulations. - FM * Additions to the online help. - FM * Unescape any hex escaped username and/or password in ftp URLs. - FM 02-20-96 * Handle timeout disconnects of cached NNTP connections. - FM * Allow head or tail match specifications (e.g., comp.infosystems.* or *.unix) in news, nntp and snews URLs (That's illegal, so don't use it in public documents.). - FM * Tweak of bookmark handling. - Ismael Cordeiro (ismael@CAM.ORG) 02-16-96 * Tweak of the new code for setting a default CHECKED radio button. - FM 02-15-96 * Issue a sensible exit message if a non-http URL is used as the startfile with -traversal. - FM * Tweaks of bookmark handling. - FM * Tweaks of Home_Dir() type casting. - FM 02-14-96 Happy Valentine's Day!!! * Tweaks of charset conversions. - FM 02-12-96 * Made inclusion of Unix DIRED_SUPPORT the compilation default, and its refinement easier to understand and set in the Makefile. - Will Mengarini (seldon@eskimo.com) & FM * Changed (X) and ( ) to [X] and [ ] for indicating checked or unchecked checkboxes. For radio buttons, we still use (*) and ( ). - FM 02-11-96 * Distinguish checkboxes from radio buttons in the Lynx display by using (X) versus (*), respectively, when they are checked or selected. - FM * Make the first radio button in a series with the same NAME checked by default if none of them had CHECKED specified. - FM 02-09-96 * Added LYK_HISTORICAL and LYK_SOFT_DQUOTES, mapped by default to the the single- and double-quote keys, respectively, for toggling valid versus "historical" comment parsing, and valid versus "old Mosaic- and Netscape-like" double-quote parsing. - FM * Added SCRIPT to the DTD and code to ensure that bad comments in its content don't generate garbage in the display. - FM * Added -DSVR4 to the make for solaris2. - KH * Use copy instead of rename in descrip.mms for putting lynx.exe in the top directory, as in build.com. - FM * Added TITLE attribute to FORM, and code to use it for the Subject in mailto ACTIONs. It's not in the spec, but better to offer it than to settle into Netscape's ?subject=foo tack-on kludge which breaks mailto for clients which haven't added code to cope with it. - FM 02-08-96 * Added -book switch for using the bookmark page as the startfile. The default or command line startfile will still be set for the 'm'ain screen command, and be used as the startfile if the bookmark page is unavailable or blank. - FM * Fixed glitch for Unix in yesterday's LYMail.c mods. - FM * Try graceful alternatives if getenv("HOME") returns NULL. - Kenneth Herron (kherron@campus.mci.net) & FM 02-07-96 * Added support for the ?subject=foo tack-on kludge to specify the Subject in mailto ACTIONs and HREFs. - FM * Convert Explorer's semi-colon Internet address separators to commas before acting on mailto address lists on Unix or VMS. - FM * Made EMBED empty again (the W3C container version has been replaced by INSERT, and Netscape still has it empty). - FM 02-06-96 * Tweaks of descrip.mms files for VMS. - FM 02-04-96 * Fixed caching of news/nntp connections so that we access the correct host when more than one has been specified. - FM 02-03-96 * Added ndash and mdash to the entities conversion tables. The W3C's DTD specifies those, whereas the text descriptions say endash and emdash, so we'll cover all the bases by supporting all four. - FM * Reduced the "en" metric for TAB to 2 per column. Was 12, to be compatible with UdiWWW, but that's pixels. You can change the enval initialization in HTML.c from 2 to 12 if you want the old behavior. - FM * Force use of DECC in build.com if that compiler is installed on VMS, and make sure external logicals don't defeat a choice of DECC via descrip.mms. - FM 02-02-96 * Mods to handle lone CRs as newlines when displaying text/plain files from MAC servers. Note that they'll stay CRs when downloading, or fetching with -source, but be handled as newlines when the '\' source toggle is used for text/html files and their source is displayed as text/plain. - FM 01-31-96 * Added dummy initializers in LYCharSets.c and LYEditmap.c to ensure the modules are linked if the external model is common block and they are placed in a library. - FM 01-30-96 * For submissions of forms with a mailto ACTION, allow the user to edit the default Subject string (the TITLE of the document containing the form) via a statusline prompt, or to cancel the submission via Ctrl-G at the prompt, analogously to 'c'omments or for anchors with a mailto HREF. - FM 01-29-96 * Typo fixes in HTML.c, LYJump.c and LYGetFile.c. - PM 01-28-96 * Tweaks of redirection handling. - FM 01-27-96 * Support use of the TITLE attribute for setting the Subject in LINKs with REV="made" or REV="owner" and a mailto HREF, equivalently to its use with anchors in the BODY. - FM * Always use the parent document's URL for X-URL in mailto anchors, but still use mailto:address if it was entered as a 'g'oto. - FM * Improvements of the code in LYMainLoop.c for checking the types of links (first make sure that there are links to check 8-). - FM 01-26-96 * Made LYCharSets.c an object module instead of header for HTML.c, and created LYCharUtils.c with character-related functions from HTML.c, to reduce the size of HTML.c (got a report of memory exhaustion when trying to compile HTML.c). - FM * Added BGSOUND to the DTD and code for creating a link to the source when clickable_images is set. - FM 01-24-96 * Tweak of URL resolving when http servers return the obsolete file URL format for what are actually ftp URLs (as DEC's servers are doing). - FM * Added LYE_LOWER and LYE_UPPER for lower or upper casing lines with the line editor. Default bindings are Ctrl-K and Ctrl-T, respectively (not "intuitive" but they're the only "safe" non-printing keys left 8-). - FM 01-23-96 * Yet more tweaks aimed at getting Lynx to compile across versions of MultiNet through v3.5A and DECC through v5.2 or VAXC. Pat Rankin is trying to cope with this mess for compilations with MultiNet and his VMS port of GNUC (cross your fingers 8-). - FM * Updates of the help and about files. - FM * Tweak of sendmail path for BSDI. - Bennett Todd (bet@ritz.mordor.com) 01-22-96 * More tweaks for dealing with header conflicts in MultiNet v3.5A with DECC v5.2. - FM * Tweak of our kludge to append a 0,0 coordinate pair for ISMAP URLs. - FM * Tweaks of base handling in HTML.c. - FM 01-20-96 * Mods for builds with NetBSD, or MultiNet v3.5A with DECC v5.2 (they have conficting headers). FM & PR 01-18-96 * Improved and corrected the fatal error messages. - FM 01-17-96 * Added ability to set the NNTPSERVER environment variable via lynx.cfg if it has not been set externally (analogously to the proxy variables). - FM * Tweaks of proxy handling. - FM * Modified the "Accept-Language: " header handling so that it uses the "preferred document lang(G)uage" string without any modifications. This allows the user to specify a comma-separated string with quality values included, exactly to his/her requirements. - FM 01-16-96 * Modified the traversal code so that it always outputs to an error file if requests fail or unknown statuses are received from the http server. - FM * Added target "sun4-ncurses" to the Makefile. - Bennett E. Todd (bet@nyc.fcmc.com) * Tweaks of "preferred document lan(G)uage" and "preferred document c(H)arset" 'o'ptions handling. Send only the preference or comma-separated list of preferences in the "Accept-Language: " and "Accept-Charset: " headers. Append ", en" if "en" isn't present, and ", ISO-8859-1" and/or ", US-ASCII" if those aren't present, rather than relying on servers to honor defaults, but still don't send an "Accept-Charset: " header at all if no preference has been specified by the user. - FM * Fixed typos in the about and help files. - FM 01-15-96 * Tweaks of bold and underline setting in split_line() of GritText.c. - FM * Fixed handling of FORM start tags with no ACTION specified. - FM * Tweaks of "IBM PC character set" and added "IBM PC codepage 850" (ISO8859-1, see IBMPC-charsets.announce). - Mike Brown (mike@hyperreal.com) * Check in userdefs.h whether LYNX_CGF_FILE has been defined via the Makefile, build.com or descrip.mms. - PG * Created CHANGES2-3 with changes through release of Lynx2-3 on 04-19-94, and CHANGES2-4 with subsequent changes through the rename of lynx2-3-FM to Lynx2-4 and its release on 06-18-95, and deleted those sections from this file. - FM * Added the new Copyright and links to it in about_lynx.html. - FM 01-11-96 * Tweaks of HTWAIS.c for compatibility across versions of FreeWAIS. - FM * Unescape any hex escaped percents in mailto URLs and ACTIONs. - FM 01-10-96 * Added an LYCheckForProxyURL() function, and a PROXY_URL_TYPE return value for is_url(), so that Lynx can proxy URLs with an unknown scheme if a proxy for the scheme has been set, e.g., if "foo_proxy" has been set to "http://host/", then "foo:blah", where "blah" may or may not begin with a slash, will be handled as "http://host/foo:blah". Components of "blah" will be checked versus "no_proxy", if set, but since we don't know the default port for scheme "foo", the checks for any ports associated with the no_proxy values may not be reliable (but if we don't proxy, nor know the scheme, nor find "foo:blah" as a local file, the URL would fail, anyway) - FM * Fixed typo in VMSPrint.com. - Paul Farnham (farnham@pasco.wednet.edu) 01-06-96 * Tweak of traversal code. - FM 01-04-96 * Tweak of dynamic SOCKS mods. - TZ 01-03-96 * Added circular recall buffers for JUMP shortcuts. If multiple jumps files are installed, each has it's own recall buffer. If Lynx was built with PERMIT_GOTO_FROM_JUMP defined, any random URLs accessed via the JUMP command are placed in the goto circular buffer, not that for shortcuts, and a JUMP entry of the single character ':' for the target is treated as a command to invoke the circular buffer of previously resolved goto URLs (as if 'g'oto followed by Up-Arrow were used). - FM * Added GOTOBUFFER, homologous to JUMPBUFFER, for specifying via userdefs.h and/or lynx.cfg whether to offer the previous goto URL, if any, for reuse or editing whenever the 'g'oto command is entered, or simply rely on invoking the circular buffer via the Up-Arrow and Down-Arrow keys for accessing previously resolved goto URLs. - FM * Tweak of 'g'oto recall buffering loop in LYMainLoop.c. - AH 01-02-96 * Added circular recall buffering for 'g'oto URLs. Is invoked (if previous URLs have been entered) via Up-Arrow or Down-Arrow after entering the 'g'oto command. - FM * Added circular recall buffering for WHEREIS queries. Buffer is shared with that for ISINDEX queries, and invoked via Up-Arrow or Down-Arrow following the WHEREIS ('/') command. The 'n'ext command still uses the last WHEREIS query, not necessarily the last entry in the recall buffer, which might have been entered via a 's'earch command for an ISINDEX document. - FM * Extended treatment of FORMs which have only one INPUT (TYPE="text") field for user entries as SUBMITting on press of RETURN in that field, so that this behavior is retained if INPUT TYPE="hidden" fields are present. - FM * Tweaks of bookmark deletion sanity checks. - DT 01-01-96 (Happy New Year!!!!) * Added circular recall buffer for ISINDEX queries. Up-Arrow will cycle you from the most current query in the list to previous ones, and roll from the oldest to the most current. Down-Arrow will cycle from the oldest query to subsequent ones, and roll from the most current to the oldest. If a previous query is reused, it is removed from the recall buffer and reinserted as the most current.- FM * Plugged memory leaks in LYUtils.c and LYJump.c. - FM 12-30-95 * Added LOCALHOST_ALIAS symbols for lynx.cfg which can be set to local host aliases or to trusted hosts at other sites which will be accepted as "local" when the -localhost switch is set. - FM * Added the endash and emdash entities. - FM 12-29-95 * Use exit(0) versus exit(-1) more consistently for normal versus abnormal exits, respectively. - FM 12-26-95 * Tweak of RELOAD handling for lynxcgi URLs. - FM * More anti-crash protections for bad HTML. - FM * Tweak of dynamic SOCKS mods. - TZ 12-23-95 * Tweaks of directory building on VMS. - FM * Tweaks of log file declarations for direct wais builds. - FM * Tweak of DIRED_SUPPORT mods so that non-TAG entries don't show up when there are tagged files. - DT 12-22-95 * Added HTMake_VMS_name() to HTFTP.c for use by Unix as well as VMS with VMS ftp servers. - FM * Added INSERT and ALIAS to the DTD, updated PARAM and OVERLAY, and made FIG a paragraphing block, all as described in the 12-21-95 W3C working draft for INSERT. In contrast to FIG, the INSERT and "heritage" EMBED and APPLET elements invoke paragraphing only if their content displayed by Lynx dictates it. The rules for resolving the sources for INSERTs or for handling its ISMAP attribute are extremely complicated, and are not implemented. Let's wait to see how people in the "real world" try to make sense of them and actually use INSERT (if they do 8-). We still create source links in "clickable_image" mode for the "heritage" versions of FIG, OVERLAY, EMBED and APPLET markup, and send a 0,0 cooridinate pair for IMG with the ISMAP attribute. See comments in HTML.c - FM 12-21-95 * Fixed bug in yesterday's ftp password-handling mods that could cause a crash, and handle ftp://user:@host/path as specified in RFC 1738. - FM * Added protection against crashes for SELECT tags without the (required) NAME attribute. - FM * Added code in HTFTP.c for recognizing MS Windows (Chameleon NEWT) servers and parsing their LIST output (tested on ftp://emoryi.jpl.nasa.gov/) - FM * Another typo fix for VMS GNUC in HTFinger.c. - FM * Modified HTFTP.c to use personal_mail_address, if available, for the password with anonymous FTP. It will still use "user@" (trim off the host) if the host does not contain a dot and thus could not be a fully qualified domain name, so it will work with Unix servers such as ftp.uu.net (see get_connection() in HTFTP.c), but this will cause it to fail with MS Windows servers. - FM * Added lots more info to the trace output for the ftp gateway. - FM 12-20-95 * Modified HTFTP.c to handle a hex escaped slash (%2F) following the "punctuation" slash according to the strict provisions of RFC 1738 when connected to VMS ftp servers, so that a device can be in the path and not be mishandled as a subdirectory, e.g., the URL ftp://user:password@host/%2Fsys$common/syshlp will create a directory listing for sys$common:[syshlp]. - FM * Fixed typo for VMS GNUC in HTFinger.c. - FM 12-19-95 * Enhancements of Unix DIRED_SUPPORT (see header of LYLocal.c). - DT 12-18-95 * Tweaks of element and entity structure alignments. - FM 12-17-95 * Tweaks of APPLET CODEBASE attribute resolving. - FM * Added support for a -nosocks command line switch to turn off SOCKS proxy usage if Lynx was SOCKSified. - Thomas Zerucha (tz@execpc.com) 12-16-95 * Added the APPLET element and attributes to the DTD, and code for creating links to the Applet code via image_links - FM * Added code to handle password fields in telnet URLs. - FM * Expanded EMBED as an "attribute soup" (for compatibility with old versions of Netscape). - FM 12-15-95 * Added PARAM, and its attributes in the W3C draft for EMBED, to the DTD, and code in HTML.c to minimize the possibility of an INPUT belonging to an EMBED being misassociated with a standard FORM container. - FM * Added "first pass" EMBED handling. Should be OK with both the W3C container version and the Netscape "attribute soup" version (we'll see 8-). The clickable_image switch and toggle ('*') are now misnomers. They will cause creation of links to the EMBED SRCs whether they are images or not. - FM * Enhancements of Unix uploading (see header of LYUpload.c). - GL 12-14-95 * Modified LYUnEscapeEntities() and LYExpandString() in HTML.c to make it more likely that they'll be handled correctly across flavors of compilers. - FM * Changed NETSCAPE_QUOTES and -netscape_quotes to SOFT_DQUOTES and -soft_dquotes. - FM * Added '&' to the exclusion list for VMS suggested file names. - FM 12-13-95 * Added CAN_ANONYMOUS_GOTO_TELNET_PORT symbol which if set TRUE in userdefs.h will allow anonymous users to specify a port in 'g'oto commands for telnet URLs. - FM * Added NETSCAPE_QUOTES symbol which if set TRUE in lynx.cfg will cause Lynx to emulate the Netscape bug of treating '>' as a co-terminator of a double-quoted attribute value and the tag which contains it. - FM * Forgot to define FORM_LINK_RESUBMIT_MESSAGE in the distribution's userdefs.h for yesterday's mods. - FM * Forgot to put the HTFile.c with the LIST_FORMAT mods into the distribution (maybe I should just concentrate on Christmas 8-). - FM 12-12-95 * Changed handling of the no-cache META directive so that it applies to the document which contains the META tag, rather than to any form submit buttons within it. The form's CGI script should return a stream which contains the directive to force resubmissions, and any (e.g., ISINDEX) script or (e.g., foo.shtml) document can include the directive to force reloading by Lynx. - FM * Added ALWAYS_RESUBMIT_FORMS symbol in userdefs.h and lynx.cfg for setting forced resubmissions of forms, and a -resubmit_forms command line switch for toggling the default. - FM 12-11-95 * Moved values of LYStrings.h function key definitions from 0x80 - 0x8D to 0x100 - 0x10D and modified all the structures and functions in LYKeymap.c and LYEditmap.c accordingly. - FM * Added the KOI8-R (Russian) character set. - Andrey A. Chernov (ache@astral.msk.su). * Replace gets() with fgets() for the Unix setup() in LYCurses.c - AAC * Tweaks for building with FreeBSD. - AAC & FM * Added handling of META directives for ISO-8859-2 and KOI8-R if the document is text/html and a server header didn't already set the charset. - AAC & FM 12-10-95 * Tweaks of memory management. - FM * Made the LONG_LIST parameters for Unix local directory listings configurable via userdefs.h and lynx.cfg - DT 12-09-95 * Added code for re-computing and retaining the current link if it is still on the page when using the LYK_UP_TWO and LYK_DOWN_TWO commands. - FM * Added support for nested emphasis tags (they're all still displayed as HT_UNDERLINE, but no longer terminated prematurely). - FM 12-08-95 * Added more suffix maps in HTInit.c. - FM * Tweak of META attribute definitions. - FM 12-06-95 * Don't reject LYNXKEYMAP and lynxcgi URLs with the -localhost switch. - FM 12-05-95 * Made the loaded_texts list in GridText.c functionally "circular", so that returning to a cached document causes it to be treated as the most current, and dumps of cache, when necessary to load a new document, are done for the least recently viewed rather than least recently fetched document. - FM * Show the METHOD and ACTION in showinfo() of LYShowInfo.c if invoked when the cursor is positioned on a submit button. - FM * If the user mode is advanced, keep showing the URL in the statusline when Lynx is in forms mode but the link is not a form field. - FM 12-03-95 * Tweaks of code for submissions of forms with only a single INPUT (TYPE="text") field. - FM 12-02-95 * Treat any META directives with a NAME or HTTP-EQUIV value of "Pragma" or "Cache-Control" and a CONTROL value of "no-cache" as an instruction always to resubmit any form(s) in the document. - FM * Added parsing of META directives. Functions can be added where indicated in HTML.c. - FM * Include the HTTP/1.1 "Cache-Control: no-cache" header together with the HTTP/1.0 "Pragma: no-cache" header for reload or resubmit requests. - FM * Fixed bug in the check for an all-space ALT in IMG when creating a link for its SRC. - FM * Fixed parsing of square-bracketted DOCTYPE fields. - FM 12-01-95 * Improvements of logic for indentations within lists. - FM 11-30-95 * For resiliency, treat upper case letters as equivalent to lower case in scheme names (e.g., allow "HTTP" as well as "http"), by converting them to the appropriate case before entering them into the anchor hash table or otherwise acting on them. - FM * Added ability to change the default reply to the "really quit" prompt from "[Y]" to "[N]" via a compilation symbol in userdefs.h. - DT 11-29-95 * Added ALIGN attribute for HR (default is "center"). - FM 11-28-95 * If a form has a single field, and it's INPUT TYPE="text", treat RETURN as a submit command for it. - FM * Added START as a synonym for the SEQNUM attribute in OL. - FM 11-27-95 * Enhancements of the wais gateway. - FM 11-26-95 * Fixed up HREF, ACTION and SRC resolving to be conformant with RFC 1808 (except that we don't yet support a ";params" field). - FM 11-25-95 * Tweaks of yesterday's jumps file mods. - FM 11-24-95 * Enhancements of 'J'umps file handling, including ability to install multiple jumps files mapped to different keys and associated with different statusline prompts and recall buffers. - DT & FM * Deal with ALTs that have only spaces when in clickable_image mode. - FM * Worked in WM's mods to make the REVERSE_CLEAR_SCREEN_PROBLEM workaround a configuration option via ENABLE_SCROLLBACK in lynx.cfg and a command line toggle (-enable_scrollback), for use with comm programs which have screen display buffers that can be accessed for review independently of the Lynx commands (see comments in lynx.cfg). - FM 11-23-95 * Use the BASE, if present, instead of the original document URL, as the default ACTION for forms. - FM * Tweaks of paragraph alignment handling. - FM * Make sure we don't realloc() a NULL env pointer in LYCgi.c. - DT * Cancel bookmark deletion if the line does not have a complete link or if there is more than one link on the line. - DT 11-21-95 * Fixed bad logic in the setting of bold and/or underline starting points in new lines created via split_line() of GridText.c. - FM * Added case KEY_BACKSPACE in LYgetch() of LYStrings.c. - GL 11-19-95 * Fixed problem of SELECT causing all immediately following white space to be ignored. - FM * More tweaks of paragraphing, and handling of labeled blocks within PRE blocks. - FM 11-18-95 * Added INFOSECS, MESSAGESECS and ALERTSECS symbols in userdefs.h and lynx.cfg for setting the durations of statusline pauses (important when using Lynx with a braille-based access). See comments in userdefs.h and lynx.cfg for more information. - FM * More tweaks of paragraph handling. - FM * Include the Reference lists is crawl output files if the -number_links switch was included and the -nolist switch wasn't. - FM 11-17-95 * Tweaks of finger and telnet gateways. - FM * Added handling of MARQUEE equivalently to BANNER. - FM * Various tweaks of 8-bit character and related HTML handling (OLs or ULs without attributes or some wrong combinations were crashing Lynx). - FM 11-16-95 * Implemented the ID attribute for TAB, and the TO and INDENT attributes when its ALIGN attribute is "left" (the default) and the style's alignment is HT_LEFT (the default). If these conditions don't apply, or if the TAB target is outside the current margins or would overlap prior text, a collapsible space is inserted instead of TABing. The INDENT values are in "en" units, treated as 12 per column. Added tabtest.html in the test subdirectory to illustrate TABing. - FM 11-15-95 * Added the HTML 3.0 DTD structures and definitions for SPOT, and fully implemented it (use SPOT ID="foo" as SGML_EMPTY instead of named anchors with no content). - FM * Added the HTML 3.0 DTD structures and definitions for TAB. For now, it simply puts a collapsible space in the text stream if the TO attribute is present. - FM * Added the top-level HTML 3.0 DTD structures and definitions for MATH, and implemented it's ID attribute. The markup is captured as HTML_LITTERAL, and until we have a processor, is output as is, in brackets to alert the user about the situation. - FM 11-14-95 * Tweaks of LYK_UP_LINK and LYK_DOWN_LINK handling, and added them to the default mapping as '<' and '>'. - FM * Tweaks of LYK_TOOLBAR handling. - FM 11-13-95 * Added LYK_TOOLBAR (mapped by default to '#') for jumping up to the pseudo Toolbar or Banner if present in the current document. Using '#' instead of Home to jump there allows you to Left-Arrow back to where you were in the current document. Set up a BANNER in about_lynx-dev.html to serve as an example of this feature. - FM * Added the HTML 3.0 DTD structures and definitions for BANNER, implemented its ID attribute, and set it up to act as a pseudo Toolbar if one hasn't been set up already via REL attributes of LINKs. - FM * Tweaks of paragraphing for CAPTION, CREDIT, FOOTNOTE, and NOTE. - FM 11-12-95 * Handle (i.e., ignore) any P that immediately follows an LI, DT or DD. - FM * Cancel any file fetch and viewer spawn or launch during traverals. - FM 11-11-95 * Added finger gateway (finger://host[/request]) based on patches from Martin Hamilton (martin@mrrl.lut.ac.uk). - FM * Added LYE_TAB for mapping keys to act as LYE_ENTER, but return '\t' so that the behavior of TAB is emulated in TEXTAREAs, and mapped Do to LYE_TAB in the default binding. - FM * Fixed glitch in handling of DEC extended characters which contain two digits (affected Do and Find). - FM * Better documented that disabling access to hidden (dot) files also disables ability to create such files via Lynx. - FM 11-10-95 * Added handling of mailto as a form ACTION. See http://www.q-d.com/swc.htm for software to extract and unescape the mailed content. - FM * Added lynxprog URL handling, which is identical to lynxexec URL handling except that the user is not prompted to enter RETURN before returning to Lynx. Use lynxprog for scripts or programs such as mail which do not need an enforced pause to let the user read the screen output. - FM * Removed code in HTFile.c for treating ',' as a synonym of '.' for hidden files (nobody seems to know why that was being done 8-). - FM * Moved inclusions from LYBookmark to tcp.h. - FM 11-08-95 * Extend optional hidden (dot) file/directory support to Unix, and embellished it on VMS and Unix with regulation via a command line switch and 'o'ptions menu setting. See userdefs.h and lynx.cfg for more information. - GL & FM * Added support on Unix for straight tar files and a compile time option that disables the ability to extract files from an archive file (since there is no control over the files extracted). - GL 11-07-95 * More tweaks of 8-bit character handling. - FM * Added "Macintosh (8 bit)" character set. - Neil K. Guy (nkg@freenet.vancouver.bc.ca) * Added "Example Lynx Optimized User Home Page" to the online 'h'elp. - FM 11-05-95 * Fixed Cc: header handling for email on Unix. - FM 11-04-95 * Reference the current character set for any raw 8-bit characters in text/plain streams (but don't translate named or decimal escaped entities, since that's specific for text/html). - FM * Block any illegal control or escape characters in text/plain streams, to avoid problems if a binary ftp or local file was mistyped and sent to the screen as that Content-type. - FM * Eliminated mod in SGML.c which emulated Netscape's bug of treating '>' as both a close-double-quote and close-tag (Netscape v2.0 fixed its bug, so hopefully the bad HTML with it will go away. 8-). - FM 11-02-95 * Assume an ISO-8859-1 character set for all local files. If it's actually ISO-8859-2 and the terminal is using that, set the Lynx CharSet option to "ISO Latin 1" so that 8-bit characters will be sent raw to the terminal. - FM * Added Martin Ramsch's iso8859-1.html to the test subdirectory. Use it to complete the conversion tables in LYCharSets.c. - FM * Don't block insertion of a lead space for INPUTs in PRE blocks, so alignments will be compatible with those of graphic clients. - FM * Don't block all access to the 'p'rint menu for the print restriction (should still offer printer options which have the TRUE flag set; all access is still blocked for -validate). - FM * Replaced the STDfoo_FILENO symbols in LYCgi.c with the more portable fileno(stdfoo). - WM * Added NCURSESINCDIR compilation symbol for setting the path to the NCURSES header file in LYCurses.h to that of the latest version. - GL * Tweaks of interrupt handling on VMS. 10-31-95 * Added more suffix maps in HTInit.c. - FM * Mods in LYCgi.c which hopefully makes the code more portable across Unix flavors. - FM 10-28-95 * Tweaks of global flag initializations and resets in HTML.c. - FM * Added RESOLVLIB symbol in the top Makefile for including -lresolv in the LIBS= list, if needed, for SUN 3 or 4 OS, and comments about that in the Makefile, and INSTALLATION and PROBLEMS files based on an explanation from Will Mengarini (seldon@eskimo.com). - FM 10-27-95 * Mods of top level Makefile: Added NOPORT compilation symbol for forcing use of PASV in ftp URLs. Added NO_S_IFSOCK compilation symbol for Unix flavors which lack an S_IFSOCK definition for lstat(). - FM * Reload the current document whenever the character set is changed. - FM * Don't reference entities for raw (or decimal escaped) 8-bit characters if the document is not text/html, or for any local files if the charset is Latin. - FM * Made Ctrl-H a synonym for DELETE instead of Left-Arrow in the line editor. - FM 10-25-95 * Handle all characters in strings for the new line editor as unsigned so they don't go negative if 8-bit. - DW * Restored proper handling of the MAXLENGTH attribute in INPUTs for strings entered with the new line editor. - FM 10-24-95 * Deal with all non-printing characters when setting up the SELECT pop-up window strings. - FM * Handle raw 8-bit characters via reference to the ISO-LATIN1 named entities so they in turn can be referenced to the currently selected character set. - FM * Yet more tweaks of non-breaking space handling. - FM 10-22-95 * Improved treatment of the startpage URL with -traversal so that it only blocks traversals of links on other servers. Any links on the same http server which shouldn't be traversed may be blocked via explicit and/or wildcarded entries in REJECT.DAT. Updated CRAWL.announce to make this more clear. - FM * Typo fixes in top-level Makefile. - Steve Jeske (jeske@pa.dec.com) 10-21-95 * Handle decimal escaped entities via reference to the ISO-LATIN1 named entities so they in turn can be referenced to the currently selected character set. - FM 10-20-95 * Tweaks of formatting for LONG_LIST directory lists and README file inclusions in HTFile.c and HTVMSUtils.c. - FM * Tweaks of decimal escaped non-breaking space handling in HTML.c. - FM * Force unescaping of hidden VALUEs for INPUTs as ISO-LATIN1. - FM * Added ".shtml" and ".htmlx" as text/html extensions in HTInit.c. - FM 10-18-95 * Made parsing of the name and address out of the NNTP From: header more reliable in HTNews.c. - FM * Added "LYNX_TEMP_SPACE" environment variable (Unix) or VMS logical, which if present at run time will be used instead of the the TEMP_SPACE definition in userdefs.h as the path prefix for temporary files. - FM 10-17-95 * Added TYPE attritute for OL, and coordinated it with the SEQNUM and CONTINUE attributes. The default TYPE is "1" (Arabic numbers), and SEQNUM values for it can range from -29997 to the system's maximum integer. The Alphabetic TYPEs are "A" (upper case) and "a" (lower case), and can range from 1 (" A." or " a.") to 18278 ("ZZZ." or "zzz."). The Roman TYPES are "I" (upper case) and "i" (lower case), and can range from 1 (" I." or " i.") to 3000 ("MMM." or "mmm."). SEQNUM values should always be Arabic, and will be converted to other types (e.g., SEQNUM="27" TYPE="a" will yield "aa." for the next LI). The CONTINUE attribute will cause the sequence and TYPE of the preceding OL to be continued for LIs in the current OL. - FM 10-16-95 * Treat a value of "*" for "no_proxy" as a global override of any existing proxy variables. - FM 10-15-95 * Deal with raw or decimal escaped non-breaking space characters in SGML_character() of SGML.c and LYUnEscapeEntities() of HTML.c. - FM 10-14-95 * Updated info about lynx-dev in lynx.man and lynx.hlp. - FM * Don't force LINKS_ARE_NUMBERED in dumps if -nolist was included. - FM * Output the References list for dumps with OL-style numbering. - FM * More tweaks of "anti-spoof" handling for telnet URLs. - FM 10-13-95 * Block direct access to the telnet prompt for telnet URLs entered without a host field. - FM * Include the TRUSTED flag in spawns for OpenVMS/AXP v6.1 or greater. - FM 10-12-95 * Convert any strings in news articles that look like URLs into links. - FM * Use the Followup header in news articles, if present, for followups. Otherwise, use the Newsgroups header. - FM * Ignore any invalid ISO 646 7-bit control characters or ISO 8859 8-bit control characters in SGML_character() of SGML.c. - FM 10-11-95 * Typo fix in HTTCP.c for non-MULTINET VMS builds. - Gary Chow (garyc@mrs.com) 10-09-95 * Assume the root as path in HTParse() of HTParse.c if the access and host but no path are given, and the access is http, https, or ftp. - FM 10-05-95 * Make sure the FREE(x) macro gets defined for HTTCP.c. - FM 10-04-95 * Mods in HTTCP.c to prevent string buffer overruns. - FM * Prevent possible string buffer underrun for terminal white space trims in GridText.c. - Renato Buda (renato@peoplebank.co.uk) 10-01-95 * Updated the listserv and archive addresses in the about and help files. - FM 09-30-95 * Added support for Windows_NT FTP servers. - FM * Added ability to send a self copy of mail via a Cc: header on Unix (sending of self copies is set via the mail software itself on VMS). - FM * Tweaks of SOCKET_ERRNO handling in HTTCP.C. - FM * Include unistd.h more consistently on Unix (via tcp.h) if NO_UNISTD_H is not defined. - FM * Modified the FreeBSD and NetBSD libwww Makefiles to use the CommonMakefile. - FM * Makefile addition (snake3) for the HP-UX purchased compiler. - Andy Finkenstadt (genie@panix.com) 09-29-95 * Deal with HTAlert.c function calls to LYgetstr(), e.g., for a password, when doing a -dump or -source non-interactive fetch. - FM * Output HTAlert() messages to both stderr and stdout in TRACE mode. - FM 09-28-95 * Added a description of the line editor's default key bindings to the help file set. - FM * Tweaks of the line editor. - FM * Declare DCLspawn_exception() in LYCurses.c as unsigned int only for DECC (otherwise as int, for VAXC and GNUC). - FM 09-27-95 * Added common line editor for forms and prompted queries, with configurable line editor key bindings. See LYStrings.h and LYEditmap.c for the default configuration. - DW & FM * Tweaks of build.com's symbol assignments when in batch mode. - MM 09-22-95 * Added ISO-8859-2 CharSet, and mods for Accept-Charsets handling based on patches from Mark Martinec (Mark.Martinec@nsc.ijs.si). - FM 09-19-95 * Tweaks of OL attribute handling. Allow negative SEQNUM values. Keep better track of CONTINUE versus non-CONTINUE OL sequences within nests. Allow CONTINUE in the first OL of a new nest, set to the last LI count of the previous nest (at any depth in that previous nest). - FM 09-17-95 * Tweak of LYUnEscapeEntities() in HTML.c. - DW & FM * Another tweak of groupid handling in LYShowInfo.c. - DW * More fixes of 7-bit character approximations. - DW * More help and about file tweaks. - DSL 09-16-95 * Added the HTML 3.0 DTD structures and definitions for DIV, and implemented its ALIGN and ID attributes. I think I have it behaving rationally if it is used together with CENTER, LEFT and/or RIGHT (Though they're all treated as DIVs by Lynx, and shouldn't be embedded in each other, somebody will do that anyway!. 8-). - FM * Added the HTML 3.0 DTD structures and definitions for FN (Footnote). It should be handled as a popup window, but for now, it's implemented as a labelled block and has the same style and behavior as a NOTE with an ID attribute. - FM * Some compilers can't handle the continuation line in yesterday's LYCurses.h. Made it one long line. - FM 09-16-95 * Further enhanced the online help and about files. - FM * Added -DNO_FILIO_H to Makefile for SCO. - FM * Worked in stuff from 14-Sep-95 lynx2-4-2 upgrade. - FM: -------------------------------------------------------- 09-06-95 * Added patch to compile Lynx on BSDI with Ncurses package. -RK 09-06-95 * Ported Lynx to DG-UX. - RK -------------------------------------------------------- 09-12-95 * Further modified HTNews.c so that it returns unmodified news messages when the display is toggled to source ('\') or when downloading them, so uuencoded messages always can be saved without corruption, and so I also changed the SCAN_FOR_BURIED_NEWS_REFS compilation default to TRUE. - FM * Simplified a compound if() in HTParse.c which may have been giving the AIX v4.1 compiler a headache. - FM 09-11-95 * Eliminated distinct style sheets for CAPTION and CREDIT so their content will inherit the current style, and added HTML_EnsureDoubleSpace() and HTML_ResetParagraphAlignment() in HTML.c for coping with the absence of distinct style sheets for those elements, and for FIG. 09-10-95 * Added SCAN_FOR_BURIED_NEWS_REFS configuration symbol in lynx.cfg, with a compilation default of FALSE, and a -buried_news switch for toggling the default. When TRUE, Lynx scans the bodies of news articles for references and converts them to news links, but creates false news links if any email addresses are enclosed in angle brackets, and can trash uuencoded messages. - FM * Eliminated distinct style sheet for FIG so its content will inherit the current style and display appropriately within lists. Should be OK if people use valid HTML 3.0 in it's content for non-graphic clients. - FM * Added links for the W3C HTML 2.0 and 3.0 specifications and for the HAL HTML validation service to the Lynx help file set. * Made the BOLD_NAME_ANCHORS compilation symbols FALSE by default. Most documents now include emphasis tags for NAME (ID) anchors if it's desired, because the most common graphic clients don't emphasize them by default, so we should adjust to that in Lynx as well (IMHO 8-). Added emphasis tags for the NAME anchors in the Lynx help files. - FM * Eliminated forced uppercasing of H1 headers. Most documents have mixed casing and we should preserve it (IMHO 8-). Added a BOLD_H1 configuration symbol, set FALSE by default, for making H1 headers bold even if BOLD_HEADERS is FALSE. Modify the two configuration symbols in lynx.cfg for the pattern or header emphasis which pleases you. - FM * Tweak of list paragraphing. Added HText_PeviousLineSize() in GridText.c for determining if the previous line had only non-printing characters. - FM 09-09-95 * Implemented true paragraphing and the P ALIGN attribute within lists (UL, OL and DL blocks) and within ADDRESS blocks. Paragraphs within lists have one blank line inserted. Within ADDRESS blocks, a newline will be created if needed, but no blank lines are inserted. Use BR, not P, to force extra newlines within blocks. Do not place a P immediately following the LI or DD tags. Alignments of P blocks are done with respect to the "second line" margins of LI or DD elements. - FM 09-08-95 * Convert '~' to getenv("HOME") in file URLs whether or not DIRED_SUPPORT is defined. - FM * Tweak of TR and more tweaks of HR handling. Added HText_LastLineSize() and HText_TrueLineSize() functions in GridText.c for determining if lines have only non-printing characters in decisions on whether to insert additional newlines. - FM 09-07-95 * Act on Page-Up, Page-Down, Home, End, Find and Select in the form_getstr() editor (hoping they have their default mappings 8-). Also act on Remove and Control-D as delete keys in that line editor (as in the LYgetstr() line editor). - FM * Tweak of HR handling. - FM * Mods to prevent creating multiple copies of temporary printer files. - FM * More fixes for NeXT. Temporary files for VIEWER, DOWNLOADER or PRINTER commands on NeXT all have the ".html" default suffix replaced with ones indicative of the Content-type. - FM 09-06-95 * Mods to prevent creating multiple copies of temporary viewer or downloader files. - FM * Fixes for NeXT. - FM 09-05-95 * Enabled the -help switch when no configuration file is available and Lynx would otherwise exit (i.e., it now outputs the help message before it exits). - FM * Documented the -child switch. - FM * Fixed and documented the -nolog switch. - FM * Changed the -linknums switch to -number_links, fixed the code to work, and documented the switch. - FM * Made handling of escaped colons (\:) in VIEWER commands reliable. - FM 09-04-95 * Implemented the PLAIN attribute for UL, and the SEQNUM and CONTINUE attributes for OL. - FM * Updated the DTD structures and definitions for DD, DL, DT, LI, OL and UL to HTML 3.0, added LH, and implemented full HTML 3.0 ID handling for those, and B, BLINK, BR, CENTER, CITE, CODE, DFN, DIR, EM, FORM, KBD, I, LEFT, LISTING, MENU, PLAINTEXT, PRE, RIGHT, SAMP, STRONG, TT, U, VAR and XMP (some of which are obsoleted in HTML 3.0, but what the heck 8-). - FM 09-03-95 * Made bolding of NAME (ID) anchor contents configurable in lynx.cfg. - FM 09-02-95 * Tweaks of FIG and OVERLAY handling: Only put up [FIGURE] (and +[OVERLAY]) links if clickable_images is set. Assume P ALIGN="left" if contained text does not begin with an explicit tag that sets an alignment. - FM * Implemented full HTML 3.0 ID handling for IMG. - FM * Tweaks for FreeBSD. - Masafumi NAKANE (t94303mn@sfc.keio.ac.jp) 08-31-95 * Added support for using a TITLE attribute as the subject in anchors with a mailto HREF (A HREF="mailto:address" TITLE="RE: subject"). - FM 08-30-95 * Implemented full HTML 3.0 ID handling for A, ADDRESS, BLOCKQUOTE, BQ, CAPTION, CREDIT, FIG, H1 - H6, HR, INPUT, NOTE, OPTION, P, SELECT, TABLE, TD, TEXTAREA, TH and TR. - FM * Updated the DTD structures and definitions for ADDRESS to HTML 3.0. - FM * Block insertion of any escape sequence characters or substitutes when editing form INPUTs or TEXTAREAs. - FM 08-29-95 * Tweak of ALIGN attribute handling in paragraphs. - FM * Protect against hanging on escape sequences if received (illegally) in documents typed as text/plain or text/html. - FM 08-28-95 * Declared DCLspawn_exception() as an unsigned int to keep DECC happy. - FM 08-27-95 * Give LYUpload() a return value (because LYLocal.c has been testing for one all these years 8-). - FM * Force reload on return from 'o'ptions menu if HTfileSortMethod or keypad_mode are changed. - FM * Force no cache of keymap display whenever vi_keys or emacs_keys are changed. - FM * Added Remove and Control-D as Delete synonyms for removing characters to the left of the cursor in the LYgetstr() line editor, and Control-F as Right-arrow synonym for moving the cursor to the right. - FM 08-24-95 * Modified prompted string editing via LYgetstr() along lines in patch from PM (editing of form INPUT and TEXTAREA strings is unchanged). Here's how the prompted string editing works: Left-arrow and Backspace (Control-H) move the cursor to the left, and Right-arrow to the right, within the string. Characters are INSERTed at the cursor position. Delete removes characters to the left of the cursor. Home, Find and Control-A move the cursor to the beginning of the string. End, Select and Control-E move the cursor to the end. Control-U erases the string. Control-G cancels at any time. Return accepts if a string is present, or cancels if it was fully erased or never entered. A right-curley brace appears in the right-most column when the string has segment(s) scrolled off screen, and if left scrolled, the cursor sits on it for further editing with the above command keys (or acceptance via Return). Long strings scroll both left and right between the prompt string and right-curley brace. Had to modify 17 files to make this line editor crash safe (I hope people like it! 8-). - FM 08-22-95 * Use a macro in parse_arg() of LYMain.c to ensure proper handling of switches which take a value and might have a space instead of an '=' between the name and value. - DW * Insulate any system RTL's getline() from the one in HTInit.c. - DW * Enabled editing of titles when adding bookmarks. - FM 08-21-95 * Fixed the IBM PC character set in LYCharSets.c (Note: The PC-set has the currency symbol but it is a control character - ^O - so there is a chance that curses or the user's terminal may discard it. Did not fix the Icelandic characters). - DW * Check whether getpwuid() and getgrid() have returned NULL pointers in LYShowInfo.c. - DW * Break up the too elaborate, compound assignment statements in LYList.c so no compilers get tripped up by evaluation order effects. - DW * Worked in mods from DW to cope with CR, CRLF or LF all as EOL in HTML.c and GridText.c (not sure if they take into account all of the consequences of Lou's "big cheat" in GridText.c, but they appear to, so far). - FM * Explicitly preserve the Lynx bookmark file mode on Unix. - DSL 08-20-95 * More documentation and help updates. - FM 08-19-95 * Updated INSTALLATION and comments in userdefs.h and lynx.cfg. - FM * If save to disk was done via the download menu, and a VMS rename() attempt succeeded so we don't spawn a COPY, we no longer can access the file via the download menu, so pop in that situation. - FM * Worked in stuff from 16-Aug-95 lynx2-4-2 upgrade. Most had already been added to lynx2-4-FM. This is the new stuff. - FM: --------------------------------------------------- 08-16-95 * Applied patch from Peter van Heusden (pch@ucthpx.uct.ac.za) to fix a bug when lynx encounters an OPTION tag before the style is ever updated. - CL 08-09-95 * Added some tweaks to Makefile and LYCurses.h to get lynx to properly compile on ISC. Thanks to Robert Salter (salter1@master.nsbf.nasa.gov). --------------------------------------------------- 08-18-95 * Added a -validate switch for turning off everything except http URLs, helpfiles, and secure menus in Lynx. Can be used with -dump in CGI scripts, but is intended for use with anonymous telnet logins. In the latter case, the user can start with his/her server's or userdir homepage, and validate everything, while able to manipulate the display features (e.g., whether or not links are numbered) and turn on trace (Control-T, then Control-R to reload) when a "Bad HTML" document is encountered. The telnet approach is particularly useful when used with the 'l'ist feature. When used with -dump, compare it with versus without -nolist. - FM * Added a missing curley brace in EF's (08-16-95) patches. - FM 08-17-95 * Added HISTORICAL_COMMENTS symbol which if set TRUE in lynx.cfg will cause Lynx to revert to the "historical" behavior of treating any '>' as a comment terminator instead of (a valid) '-->', and a -historical switch for toggling the default behavior. - FM * Added a -nolist switch for turning off the link list feature in dumps. - FM * Modified SGML.c so that it still substitutes the expected end tag if a different one is encountered (e.g, due to a document having interdigitated instead of validly embedded tags), but doesn't do a wind down of the element stack. This gives it a better chance of recovering from bad HTML, and the sanity checks I've added thus far in HTML.c appear to still be adequate for avoiding crashes (we'll see 8-). - FM 08-16-95 * Mods to support within-document anchors in documents returned via lynxcgi scripts. - FM * Worked in EF's patches to handle changes of keymaps under DIRED_SUPPORT with OK_OVERRIDE, and to give the user some feedback during an Install command. - FM 08-15-95 * Don't include a Referer header for 'g'oto URLs. - FM * Added patches from PR for compilations with VMS port of GNUC: Modified several prototypes to avoid GNUC warnings about conflicts with ones in lib$routines.h, and added code in HTVMS_WaisUI.c to deal with an obscure glitch for GNUC v2.6.[123] and v2.7.0 (not present in v2.6.0 or earlier, and fixed in v2.7.1). - FM * Worked in code from PR as LYVMS_FixedLengthRecords() in HTFWriter.c to change attributes of binary files on VMS from Stream_LF to FIXED 512, no implied carriage control, best try contiguous. Replaces the spawn to execute FIXED512.COM. - FM 08-14-95 * Modified TEXTAREA handling to succeed or fail on bad HTML equivalently to Netscape. - FM 08-12-95 * Mods to avoid crashes and to do something reasonable with OPTION strings that are wider than the available popup window width. Truncation is indicated by omission of a terminating ']' in the window link, and the window, when popped up, is made equal to the screen width (but we can't wrap the strings within the window, so they're truncated if they still don't fit). - FM * Mods to handle INPUT fields that are packaged in PRE and would extend past the wrap column. No way to make that perfect without a major redesign, but it's better now. - FM 08-10-95 * Handle 'g'oto entries equivalently to STARTFILE and HOMEPAGE, i.e., if the user's entry isn't a URL, convert it to a file URL if it's a file or directory on the local system, otherwise convert it to an http URL. For example, "~/" will be converted to a file URL for listing the HOME directory (on both Unix and VMS), and "www.netscape.com" will become "http://www.netscape.com". - FM * Fix LYCurses.h to deal with definitions of TRUE and FALSE in cursesX.h on ultrix. - Brian Exelbierd (bex@ncsu.edu) * Made SYSTEM_MAIL, and MAIL_ADRS on VMS, configurable in lynx.cfg. - FM 08-08-95 * Fixed two initialization problems that could account for reports of inappropriate HEAD requests in pops of cached documents. - FM * More tweaks for coping with bad HTML. - FM * Fixed bug in code for bypassing bad SUFFIX: or VIEWER: entries. - FM 08-06-95 * Added code in GridText.c to deal with syntactically OK but symantically nonsensical uses of ALT="" in IMG tags (i.e., when the IMG is structured to provide the anchor for a link, and so the anchor ends up with nothing but nonprinting characters for bolding), and removed the forcing of an "[ISMAP]" pseudo-ALT in HTML.c. The show_anchor element in TextAnchor structures is now set to NO whenever an anchor does not have any printing characters. - FM * Modified HTML.c to issue only one "Bad HTML" statusline message per document (unless it's one of those unbelievably bad CGI script outputs that are functionally multiple, concatenated documents 8-), and similarly for "Table in Form" and "Form in Table" informational messages. - FM * Don't bother prompting whether to send a HEAD request for the current document if there are no links on the page (but still prompt if the user makes a HEAD request when positioned on an inappropriate form link). - FM 08-05-95 * Added code in SGML.c for storing Identifiers (e.g., !DOCTYPE) and Comments (i.e., tags beginning with !--) and for reporting them in trace mode. Serves as a model for actually using them someday (i.e, functions for analyzing them could be called where we presently just invoke a trace output to stderr). - FM 08-03-95 * Modified SGML.c to handle comments as in the current specs, and put Paul Gilmartin's (pg@sweng.stortek.com) TestComment.html in the test subdirectory. - FM * Added binary extensions in HTInit.c that were giving people problems on FTP servers. - FM 08-02-95 * Added explicit check for CMU in telnet support with SOCKETSHR-built images. - SB * Added -link switch for setting the count in lnk#.dat files with -crawl (needed if you interrupt a traversal and want to pick up again where you left off). - DM * More tweaks of -traversal code and Makefile. All known bugs appear to have been dealt with at this point. Updated lynx.man, lynx.hlp and help files to include the -traversal and -crawl switches. - FM 08-01-95 * Changed the SEQUENT compilation sympbol to PTX2 and added a ptx2 procedure to the Makefile for Sequent Symmetry DYNIX/ptx v2, because more current versions reportedly have solved the problems which the conditional compilation attempted to address. - FM * Force in the "[ISMAP]" pseudo-ALT if someone uses ALT="" for an IMG tag that has ISMAP specified. - FM * Tweaks of the -traversal code (still experimental). - DM & FM 07-31-95 * Worked in code from David Mathog (mathog@seqaxp.bio.caltech.edu) for implementing the TRAVERSAL function from old versions of Lynx, but via a command line switch (-traversal) instead of in a separately compiled executable, and for a CRAWL function, invoked via a command line switch (-crawl), which allows Lynx to be used as the front end for a Web Crawler. See CRAWL.announce for more information. - FM * More tweaks of LYCurses.c and LYCgi.c for GNUC on VMS. - SB * More tweaks of src/Makefile. - DSL 07-30-95 * Tweaks of yesterday's Makefile and descrip.mms files. - FM 07-29-95 * Tweak in HTFTP.c to ensure that Lynx doesn't sit around waiting for an FTP server's good-bye message if the server closes the connection itself and doesn't send one. - FM * Added GNUC support to the VMS descrip.mms files. - FM * Tweaks of HTWAIS.c socket handling on VMS (I can't reproduce a reported problem with SOCKETSHR/NetLIB, but these tweaks might help). - FM * Added my guesses at code for HTTelnet.c to implement telnet, tn3270 and rlogin support, if available, when building with SOCKETSHR/NetLIB on VMS. - FM 07-28-95 * Mods for Sequent Symmetry DYNIX/ptx - Mark Kolmar (mkolmar@ccs.nslsilus.org) * Added GL's lynxcgi patches posted to lynx-dev, plus some tweaks. - FM * Worked in GL's lynxcgi mods as in Lynx2-4-2: -------------------------------------------- Added George Lindholm's LYNXCGI feature. This allows lynx to bypass http daemons to run local CGI scripts using a URL of the form "lynxcgi:/path/cgi-script". To implement in Lynx, LYNXCGI_LINKS must be uncommented in userdefs.h and TRUSTED_LYNXCGI must be fixed in lynx.cfg. It doesn't handle redirection or mime-types and scripts should probably generate partial URLs when referring back to itself. If the file you're going after isn't an executable then it will be loaded as regular file. This makes it possible to go back and forth between cgi-scripts and .html files. I changed the way TRUSTED_LYNXCGIs are recorded because they don't work quite the same as TRUSTED_EXECs do. Also, George says it works fine on SunOS and Solaris, and it seems to work fine on Linux. - CL -------------------------------------------- * Don't block access to the download menu when both no_download and no_disk_save are set if any of the download commands have always_enabled set (ie. present a reduced menu, with those still available). - FM * More tweaks of help and html files. - DSL 07-26-95 * Added support for GNUC in the VMS .com files. Should now compile and link automatically for GNUC via build.com, but that needs testing. - FM * Reorganized VMS option files into ones for the transport and ones for the compiler, with corresponding updates of the .com and .mms files. - FM * Tweaks of mods for GNUC on VMS, based on further discussions with SB. - FM * Tweaks of -help output. - Daniel S. Lewart (d-lewart@uiuc.edu) 07-25-95 * Ugh!! Blew it for Unix when setting up the GLOBALDEF/GLOBALREF definitions in tcp.h for VAXC vs. DECC vs. GNUC on VMS this morning (I'm a night person 8-). - FM * Worked in code for compiling with the VMS port of GNUC, based on patches from Sterling Bjorndahl (bjorndahl@augustana.ab.ca) and advice from Pat Rankin (rankin@eql.caltech.edu). Needs testing, and the linking procedure still needs to be addressed explicitly. - FM * Prevent possibility of a null pointer dereference if an ISMAP anchor fetch fails. - David Trueman (david@cs.dal.ca) 07-21-95 * Added LYK_HEAD (mapped by default to ']') to send HEAD requests for the current document or link (always sent with LYforce_no_cache). - FM * More lynx.man, lynx.hlp, help file and documentation updates. - FM 07-19-95 * Put back "-mime_headers" with mods like those in lynx2-4-2, i.e., so that a source dump is forced. Both "-mine_headers" and "-head" show the status line as well as the MIME headers. - FM * Modified "-error_file" to show the complete status line, as well as the URL and METHOD, and to concatenate entries instead of creating separate files for each request. - FM * Updated the lynx.man, lynx.hlp and lynx_help files. - FM 07-18-95 * Changed "-mime_headers" to "-head" and implemented it as a HEAD request for fetching the MIME headers as text/plain. - FM 07-17-95 * Removed 00DIFFERENT from this distribution. - FM * Made use of _underline_ format in dumps optional via SUBSTITUTE_UNDERSCORES definitions in userdefs.h and/or lynx.cfg, and added a "-underscore" command line switch for toggling the default on or off. - FM * Use system("exec $SHELL") for spawning the default shell on Unix. - Paul Gilmartin (pg@sweng.stortek.com) * Fixed typo in check for news vs. nntp URLs in HTNews.c. - Wilson Cheung (wcheung@netcom.com) * Added code to the VMS setup() for dealing with curses conflicts if someone used -post_data or -get_data without specifying -dump under conditions which require it, so it's not forced in LYMain.c as on Unix. If fact, -get_data and -post_data are very useful in interactive invocations. - FM * Fixed memory leak in the -post_data and -get_data handling. - FM * Added LYNX_HOST_NAME in userdefs.h and lynx.cfg for defining an alias which will be treated equivalently to "localhost" and HTHostName (the fully qualified domain name of the system running Lynx) in checks for URLs on the local host (e.g., when the -localhost switch is set). - FM * Added in or improved descriptions for the new switches in the Lynx command line help and Lynx_users_guide.html. - FM 07-16-95 * Tweaks of yesterday's startfile and -homepage mods, and added treatment of '~' as SYS$LOGIN when used as the lead character on VMS (e.g., on VMS as on Unix, lynx ~/ will create a listing of the login directory for the account running lynx). - FM * Worked in stuff from 13-Jul-95 lynx2-4-1 upgrade. Most had already been added to lynx2-4-FM. This is the new stuff. - FM: --------------------------------------------------- 07-13-95 * Added some command line patches from Peter Brooks - CL: (pbrooks@micromind.com). The new command lines are: -post_data, -get_data = send form data from stdin and dumps results. -auth=ID:PASSWD = sets authorization stuff at startup. -mime_header = prints mime header with -source. -noredir = prevents automatic redirection -error_file=file = prints HTTP status code to file. (Not sure of his motivation on this one, something to do with SlipKnot, I think.) (Replaced Peter's strdup()'s with more portable code. - FM) 07-11-95 * Added Erik Olson's (olson@phys.washngton.edu) patch to use the _underline_ format when using the -dump option. - CL (Kept the old code, #ifdef'ed out, to make this optional someday. - FM) 07-07-95 * Fixed a bug in local_dired. Specifically, a pointer to a fixed array was being fed into StrAllocCopy as the destination. Linux was choking on this although OSF/1 and AIX seemed to handle it better. - CL --------------------------------------------------- 07-15-95 * If a command line "startfile" and/or -homepage is not a URL, and can't be located as a file or directory on the local system, treat it as an http URL, e.g., www.wfeb.edu will be treated as http://www.wfeb.edu - FM 07-13-95 * Added nntp URL handling (nntp://news_host[:port]/path). Made it read access only (use news URLs for both read and post access). - FM 07-12-95 * Added code for proxying https and snews URLs. The Netsite proxy server can proxy them without need for SSL code in the clients themselves, i.e., for Lynx as publicly distributed (need client-resident SSL code and tunneling for the CERN proxy server, sorry). - FM * Added the CONNECT protocol to our local code, so that SSL URLs can be tunneled through proxy servers, and reorganized some code so that patches for the SSL hooks can be applied easily if NSA regulations are relaxed. - FM 07-11-95 * More tweaks of alignment code. - FM * Fixed bad code for removing trailing white space in GridText.c, LYrcFile.c, LYReadCFG.c and LYUtils.c. - FM * Added snews and nttp protocols, which simply inform the user that they aren't implemented. - FM * The claim is that even mere hooks to the RSA and SSL libraries are objectionable to the NSA, so I removed then from the public distribution, but left in the https protocol, which simply informs the user that it isn't implemented. - FM 07-08-95 * Worked in Lou Montulli's (montulli@netscape.com) code for https URL handling into the Common Library. To actually use it, you have to get the RSA and SSL libraries, which are restricted to US citizens (it works if you are and do 8-). I can't include those in this distribution, because by US law that would in turn restrict it to US citizens. - FM * Tweaks of paragraph alignment code. - FM 07-07-95 * If we are not allowed to change the status of the "lynxexec execution of links" from the option screen then we shouldn't be allowed to change it from the .lynxrc file either. - GL * Added George Lindholm's patch to add uudecode support to Lynx's file manager. Unfortunately, uudecode puts the uudecoded file in the current working directory, namely the directory where lynx is started. I haven't thought of a workaround yet, so I made lynx print a statusline message informing the user. - CL 07-06-95 * Modified redirection-handling code in HTTP.c to ensure that we get all of the headers before trying to track down the Location: header. - FM * For move's or rename's in the local DIRED code, don't write the new file name into the same buffer as the old. - Earl Fogel (fogel@duke.usask.ca) 07-05-95 * Added GL's mods to use a stream-based procedure for displaying the current Lynx keymap. Faster and more efficient than the temporary file-based procedure. - FM 07-04-95 (Enjoy the fireworks!!! 8-) * More mods of SGML/HTML parsing to help recover from bad HTML. - FM * Fixed some cryptic initialization problems in the Common Library's centering and right alignment code, that we're now using, by changing the malloc's in HTChunk.c to calloc's. - FM * Secured some unsafe code in the LYstrncpy() function. - FM * Increased the connect() and select() while()-looping limit in HTTCP.c to 30,000 tries. - FM * Tweak of HR WIDTH attribute handling. - FM 07-03-95 * Updated the DTD structures and definitions for HR to HTML 3.0, plus its Netscape WIDTH and SIZE attributes, and implemented WIDTH, e.g., HR WIDTH="50%" yields a centered horizontal rule half the width between the current left and right margins. - FM * Fixed problem of header end tags not yielding line breaks when embedded in CENTER, LEFT or RIGHT tags. - FM 07-02-95 * Added MAKE_PSEUDO_ALTS_FOR_INLINES in userdefs.h and lynx.cfg which can be defined FALSE to treat inlines without an ALT string as having ALT="" instead of inserting the pseudo-ALT string "[INLINE]" into the document. The configuration file default can be toggled via a -pseudo_inlines command line switch, and the user can toggle the inclusion of pseudo-ALT strings on or off at run time via LYK_INLINE_TOGGLE (mapped by default to '['). - FM * Made the -image_links command line switch a toggle for the configuration file default setting. - FM * Enabled processing of forms that use TABLE for formatting. I don't see any risk of crashes, and they might end up usable. Messages warn the user that the display of the form may be strange. - FM * Relaxed anti-crash protections for forms with bad HTML (usually due to interdigitated instead of embedded tags, written by providers with Netscape or Mosaic clients, which are insensitive to such fundamentally bad HTML). I got the code to still work with several bad forms on the Net, and if a crash should occur, the user has been tipped off via the statusline or trace message about the nature of the problem. - FM 07-01-95 * Restored the meaning of the P element to be the beginning of a paragraph, updated its structures and definitions in the DTD to HTML 3.0, and implemented its ALIGN attribute (left, center, right). Note that it no longer forces double spacing (you'll get the spacing defined in the stylesheet for the current element, which may or may not be double) and empty paragraphs (serial Ps) will not yield additional newlines (use serial BRs for that). - FM * If both download options and disk saves are restricted, don't fetch binary files with a download offer when their links are activated (just issue a statusline message that the file can't be displayed), and issue a "disabled" statusline message for any overt 'd'ownload attempts. - FM * For disk saves in LYDownload.c, on VMS attempt a rename() first, and then a spawned DCL copy if that fails. - FM * Added memory exhaustion checks for all mallocs, reallocs and callocs in the LYfoo modules. - FM * Added CL's realloc() substitute for AIX and ultrix in GridText.c. - FM * Map extensions .html3 and .ht3 to text/html in HTInit.c. - FM 06-29-95 * Added code to enable creation of links for all images. Can be made the default by setting MAKE_LINKS_FOR_ALL_IMAGES to TRUE in userdefs.h and/or lynx.cfg (not advised). Can be implemented for the session via a command line switch, -image_links, e.g., use lynx -dump -image_links to get links for all images, as well as standard links, listed in the output. Can be toggled on and off at run time via LYK_IMAGE_TOGGLE (mapped by default to '*'). Use that in conjunction with the LYK_LIST command to get a list of links that includes all images, e.g., for adding them as bookmarks. The toggle also invokes a reload, so that the change will be implemented for the current and any future documents, but if you return to cached documents, those will need to be reloaded explicitly. See comments in userdefs.h and lynx.cfg for more information. - FM * Don't restrict use of Control-T for toggling trace mode to advanced usermode (i.e., make it available in all usermodes, so people might follow the instructions in "BAD HTML" statusline messages to check the document in trace mode). - FM * Modified LYList.c to indicate the anchor NAME/ID, if present, following the TITLE, if known, in interactive 'l'ists. * Modified SGML.c to treat '>' as both a close-double-quote and close-tag. Now Lynx acts like Netscape, in that respect, so all that bad HTML Netscape users are generating will not bother Lynx. - FM 06-28-95 * Oops, missed an initialization in this morning's centering and right alignment mods. - FM * Fixed up HTML.c to bypass HTML 3.0 attribute checks for start tags generated by the Common Library's non-http access types (gopher, ftp, news, wais) Could crash, otherwise. - FM * Fixed up GridText.c code to take non-printing control characters properly into account when formatting centered or right-aligned text. - FM * Mods to improve appropriate carryover or cancelling of alignment attributes across successive elements. - FM * Implemented Netscape LEFT and RIGHT extensions, homologously to CENTER. - FM * Implemented Netscape BLINK extension as HT_UNDERLINE. - FM 06-26-95 * Updated the DTD structures and definitions for H1 - H6 to HTML 3.0 and implemented their ALIGN attribute (left, right and center). - FM * Implemented the Netscape CENTER extension. - FM 06-25-95 * Updated the DTD structures and definitions for FORM, INPUT, TEXTAREA, SELECT and OPTION to HTML 3.0. - FM * Implemented the HTML 3.0 DISABLED attribute for FORM elements. - FM * INPUT type "scribble" implemented as "text" according to the HTML 3.0 recommendation for non-GUI clients. - FM * Added protections against problems with INPUT types "range" and "file" until they're implemented (will be tricky, but do-able 8-). - FM 06-23-95 * Added all ISO8859-1 entities to the DTD. - FM 06-22-95 * Updated the DTD structures and definitions for A and IMG to HTML 3.0, and implemented their ID attribute. - FM * Tweaks of FIG handling. - FM * It is somehow inappropriate to teach our users to write correct HTML and to tell them to always check it before publishing, when Lynx's on-line help gives such a bad example :-} (not to mention versions from a couple of months back). Better now. - Mark Martinec (Mark.Martinec@nsc.ijs.si) 06-20-95 * Made the DTD structures and definitions for the HTML 3.0 elements BQ, CAPTION, CREDIT, FIG, NOTE and OVERLAY complete, and added those for STYLE, TABLE, TD, TH and TR. * Tweaks of yesterday's HTML 3.0 additions (still just "first pass"). - FM * Added code for avoiding potential problems with stylesheets and tables in HTML 3.0 documents. - FM 06-19-95 * Added "first pass" handling of HTML 3.0 elements BQ, CAPTION, CREDIT, FIG, NOTE and OVERLAY. - FM 06-17-95 * Close the configuration file on completion of the big while() in LYReadCFG.c. - PM * Added 00DIFFERENT to keep track of files in this code set which presently differ from those in the latest development code set at UKans (currently, lynx2-4-1.zip of 15-Jun-95). - FM * Tweak of the pseudo-toolbar code. The 'l'ist command now displays the TITLE (or RelValue, if TITLE is defaulted) of those links if they have never been accessed, or their actual HTML titles if accessed, at the top of the links list, so you can use that command instead of LYK_HOME to reach the toolbar links at any time, and then left-arrow to where you were in the current document instead of having to page back down to that location. - FM 06-16-95 * Added LINK REL="RelValue" HREF="foo" TITLE="TitleValue" HTML 3.0 handling (as in http://www.hpl.hp.co.uk/people/dsr/html3/dochead.html of 28-Mar-95). The HREF and REL values are required (the LINK will be ignored if either is missing or has a zero-length value). TITLE is optional, i.e., the RelValue will be used as the link name if TITLE is omitted. Currently registered toolbar RelValues are: Home, ToC, Index, Glossary, Copyright, Up, Next, Previous, Help, and Bookmark. The Bookmark links are intended to have TITLEs (e.g., "Order Form"). The others have RelValues that yield self-evident link names. The LINKs should be placed in the HEAD section, so they'll be displayed in a manner simulating a toolbar (but not a real one, since we don't have Windows and mouse support; use your LYK_HOME command to access it at any time 8-). The BODY should have a line-breaking element (e.g, H1) to set them off. For now, the Banner RelValue is treated like another toolbar element. The StyleSheet RelValue is ignored, since we don't yet have loadable stylesheet handling. - FM * Fixed up the 06-13-95 NO_ANONYMOUS_EMAIL patch to be appropriate for VMS - FM. 06-14-95 * Added LYK_LIST command ('l' or 'L'; must be uppercase if VI keys are on) for creating an ACTIVATEable list of references (links) in the current document. If LINKS_ARE_NUMBERED is on, it's a UL, otherwise it's an OL. Visited links have the TITLE displayed, otherwise the HREF is displayed. - FM * Added code to append a list of references (links), if present in the document, when -dump is used. Dumps are done with LINKS_ARE_NUMBERED turned on. The reference list is numbered, and always shows the HREFs, so that they can be referenced to the links in the document. - FM * Updated help files. - FM --- lynx2-4-1 on ftp2.cc.ukans.edu (added to lynx2-4-FM on 06-16-95) 06-13-95 * Added George Lindholm's patch to add -r (recurse) to the zip call in DIRED. - JP 06-12-95 * Added George Lindholm's new file permission patch. Here's his description: "Here is a rewamped version of my earlier file permission patch. This version uses a html page to prompt for user input (rather than having the user enter a obscure unix chmod string) using checkboxes." - JP * Added George Lindholm's addition of a compiler flag (NO_ANONYMOUS_EMAIL). If NO_ANONYMOUS_EMAIL is set the user will not be able to add their own from header. This will only work if the mail package being used will add this information. - JP --- lynx2-4-1 on ftp2.cc.ukans.edu 06-09-95 * Replaced info.cern.ch with www.w3.org in html and make files. Designated this code as 2.4-FM, for local use. - FM --- STARTING 2.4-FM --- --- Rename of Lynx2-3-FM and release as Lynx2-4 (08-June-1995) --- (see CHANGES2-4 and CHANGES2-3)
