Subject: ANNOUNCE: DJGPP port of Lynx 2.8.9rel.1 uploaded.
Reply-To: djgpp AT delorie DOT com

This is a port of Lynx 2.8.9rel.1 to MSDOS/DJGPP.


   Lynx is a fully-featured World Wide Web (WWW) client for users running
   cursor-addressable, character-cell display devices such as vt100 terminals
   and vt100 emulators running on character-cell display.  It will display
   Hypertext Markup Language (HTML) documents containing links to files on the
   local system, as well as files on remote systems running http, gopher, ftp,
   wais, nntp, finger, or cso/ph/qi servers, and services accessible via logins
   to telnet, tn3270 or rlogin accounts.


   DJGPP specific changes.
   =======================
   This port is based on the current stable release code of lynx (aka
   lynx2.8.9rel.1) available as:
     https://invisible-mirror.net/archives/lynx/tarballs/lynx2.8.9rel.1.tar.bz2

   The code has been adjusted to detect at runtime if LFN support is available
   or not.  If LFN support is available then the original posix style file
   names will be used else DOS compatible ones will be used.

   The port will use cp850 as default code page instead of using iso-8859-1 as
   it is in the current code.  It is clear that having iso-8859-1 on plain DOS
   as character set is useless as soon as spanish, german or other non-english
   texts shall be displayed.  You can always select another character set by
   either setting the corresponding environment variable or by editing lynx.cfg
   acordingly.

   The current version of lynx requires that the HOME environment variable is
   set to a writable directory or it will refuse to start.  To alleviate this
   situation, if HOME is not set, the current directory will be used instead
   by this port version.

   The port has been configured using the configure script provided by the
   source package.  This means that neither old DJGPP specific scripts nor
   makefiles distributed by the package have been used.  A lot of the porting
   work has been invested in the DJGPP specific configuration scripts.

   This port has been configured to be compiled with BZIP2, ZIP and PDCURSES
   support.  This means that if you want to recompile the preconfigured sources
   you must have installed the following ports:
     ftp://ftp.delorie.com/pub/djgpp/current/v2apps/bz2-106ar2.zip
     ftp://ftp.delorie.com/pub/djgpp/current/v2tk/zlb1211b.zip
     ftp://ftp.delorie.com/pub/djgpp/current/v2tk/pdcur36a.zip

   The port has been configured and build without NLS support enabled.
   To enable this feature, the latest ports of libiconv and gettext must be
   installed:
     ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/licv114br2.zip
     ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/gtxt192b.zip
   If you prefer NLS, then reconfigure the sources passing the nls flag to the
   config.bat file.

   The port has been configured with OPENSSL support.  OpenSSL support requires
   installing the WATT-32 port.  The following ports have been used:
     ftp://ftp.delorie.com/pub/djgpp/current/v2tk/ssl102ob.zip
     ftp://ftp.delorie.com/pub/djgpp/current/v2tk/wat3222br6.zip
   No other versions have been tested.  To be able to use this program compiled
   with OpenSSL and WATT-32 a noise source must be installed.  A noise source
   can be obtained as:
     http://www.rahul.net/dkaufman/noise063a2.zip
   If for some reason you decide to reconfigure the source package, then you
   will have to set the WATT_ROOT environment variable to point to the
   directory where the headers and the library reside.  This is:
     set WATT_ROOT=/dev/env/DJDIR/net/watt

   To be able to run the program, configuration files are expected to be found
   at their canonical place.  This is the /dev/env/DJDIR/etc directory.  The
   configuration files lynx.cfg and lynx.css are stored in the /etc directory
   and reflect, to certain extent, the conditions during the configuration and
   compilation process of this port.  You may need to adjust the entries to fit
   your requiriments.  If lynx.cfg and lynx.css are not found at their canonical
   place then the program will try to load them from the installation directory
   of lynx.  To run the program, a working version of wattcp.cfg is required.
   This file is __NOT__ distributed with this port.  That file will reflect
   your network environment and hardware.  It is the user's job write one that
   matches his environment.  As a starting point you can use the one distributed
   with the WATT-32 port.  Please note that the location of wattcp.cfg must be
   specified by setting the WATTCP.CFG environment variable.  This can be done
   either in the environment, in autoexec.bat or in djgpp.env.  If the file
   cannot be found at any of the canonical places the program will try to load
   it from the installation directory of lynx.

   To be able to run the program, a DOS packet driver (PKTDRVR) is required.
   This may be obtained from the card manufacturer or from one of the archives
   of packet drivers (such as "http://www.lanet.lv/simtel.net/msdos/pktdrvr-pre.html"
   or "http://ftp.freenet.de/pub/ftp.simtel.net/pub/simtelnet/msdos/pktdrvr/").
   Even when only browsing local files, a NULLPKT packet driver is required like
   nullpkt.zip.  The zip file can be downloaded as:
     http://www.jumpjet.info/Application-Software/DOS/Hardware/2/NULLPKT/NULLPKT.zip

   The lynx executable itself handles http:, https:, ftp:, file:, news:, nntp:
   and gopher: protocols. You will need external programs if you want to access
   telnet:, tn3270:, or mailto: URLs.  In this case a port of kermit may be
   required.

   Please note that lynx does _NOT_ support javascript at all.  So nothing will
   work that requires this feature.  If you need this, look for a different text
   web browser.

   It is important to realize that this port is a _PURE_ DOS port.  If for some
   reason you want to use lynx under Windows, you should download a windows port
   of lynx.

   If you decide to use this port as stand alone program then you can set the
   following environment variables to point to the required configuration files:
     LYNX_CFG      Set to the full path and filename for lynx.cfg
     LYNX_LSS      Set to the full path and filename for lynx.lss
     WATTCP.CFG    Set to the full path for the WATTCP.CFG directory
     SSL_CERT_FILE Set to the full path and filename for your file of
                   trusted certificates
   As a last resort, if the above environment variables are not set, the
   program will try to load those files from its installation directory.
   There is also a batch file stored in the /share/lynx_doc/samples directory
   that shows how to run lynx as a stand alone application.

   The DJGPP port now checks the OS version it is running on.  If it is equal
   or less than MSDOS 6.22 the double quotes around the file name passed to
   edit.com will be removed.  If this is not done, edit.com refuses to start.
   For OS like Win95 and above this is not necessary.  edit.com is the editor
   used by lynx at last resort.  The program's behaviour is not changed if an
   editor different from edit.com is selected in lynx.cfg.

   The DJGPP port now checks if LFN support is available.  If available then
   files with a leading dot are allowed/supported in case that this has been
   allowed by setting NO_DOT_FILES to FALSE in lynx.cfg.  In all previous
   versions, the setting of this value had absolute no influence in program's
   behviour if compiled with DJGPP.

   I have tested this port by trying to access all sites that are listed in:
     http://royal.pingdom.com/2012/06/25/using-web-browser-lynx-visit-top-websites/
   and I have experienced no issues.  I have also accessed some german and
   spanish sites to check if the special native characters are correctly
   displayed and I have found no issues.  I have also accessed www.delorie.com
   to check if the ftp support works well and if the cvs repository can be
   accessed via cvsweb interface and everthing works flawlessly.  Of course,
   the mail archives can also be accessed without issues.

   Please note that I am not a lynx user.  I have ported it as a real world
   test for the OpenSSL and WATT-32 ports.

   Only to make this point clear, if you want to use lynx as a stand alone
   program without having to care about environment variables and directories
   trees, copy lynx.exe, lynx.cfg and lynx.lss into the same directory and
   it will work.

   As usual, all djgpp specific files (diffs, README files, etc.) are stored
   in the /djgpp directory.  The sources have been configured to be build in
   the "_build" directory.  If for some reason it does not work for you,
   delete it contents and configure from scratch again.

   Please read the docs very __CAREFULLY__ to become familiar with the product.


   Here is an extract of the NEWS file showing the user visible changes from
   the last port (Lynx 2.8.9dev.16) to this one:

-------------------------------------------------------------------------------

2018-07-08 (2.8.9rel.1)
* documentation/metrics updates -TD

2018-06-10 (2.8.9pre.1)
* fix an inconsistency in message for "-listonly" option (Debian #805753) -TD

2018-05-17 (2.8.9dev.19)
* update test-packages to use current ncurses test-packages -TD
* improve portability for sockaddr structures used in HTTP and FTP, for
   IPv6 and SOCKS configurations -TD
* fix several minor warnings reported by Coverity -TD
* build-fix overlooked in 2.8.9dev.3 when INACTIVE_INPUT_STYLE_VH is defined,
   for problem introduced by 2.8.8dev.17 code-cleanup -GV
* trim unnecessary intllib symbols from src/chrtrans/makefile.in -TD
* when cross-compiling, trim LDFLAGS from makefile rule linking makeuctb,
   because it is a build tool, which should generally use BUILD_LDFLAGS
   (patch by Thomas Petazzoni)

2018-05-06 (2.8.9dev.18)
* ignore content-encoding in HTContentToCompressType() if the content-type is
   known, to improve the suggested filename (report by Russell Bell) -TD
* add support for using client certificate with OpenSSL configuration (patch
   by Elliot Thomas).
* fix a few more memory leaks -TD
* put Lynx.leaks file in home directory like Lynx.trace (report by GV) -TD
* fix a memory leak in HTFTP.c -GV
* modify HTDoConnect(), adding a check for keyboard interrupt with 'z' in the
   select-loop -TD
* modify legacy feature from Lynx 2.7.2 which checks the hostname of a URI
   to guess whether to use HTTP, FTP, etc., depending upon the prefix of the
   URIs hostname.  This is now an optional feature, GUESS_SCHEME, which defaults
   to FALSE (Debian #893907) -TD

2018-03-21 (2.8.9dev.17)
* modify samples/oldlynx.bat to check if Lynx recognizes the -lss option -TD
* modify samples/*lynx.bat to check for environment variables that Lynx would
   test for temp-directory, and only if those are absent will the scripts
   attempt to create a temp-directory -TD
* modify samples/*lynx.bat to set PATH for executing utility programs -TD
* remove unused critSec_DNS -TD
* use EnterCriticalSection in ws_netread rather than InitializeCriticalSection
   since critSec_READ was initialized in LYMain.c (report by GV) -TD
* use freeaddrinfo() in one case where free() was used (report by GV) -TD
* implement "+" item type for gopher protocol (report by James Tomasino) -TD
* add checks in options-menu in case no color-styles have been defined -TD
* add Visual Studio project files for 2010, 2012 -TD
* improve checks for strings which should not be empty -TD
* check for empty personal-mail-address (report by TG) -TD
* modify samples/lynx-demo.cfg to use SOURCE_CACHE:memory -TD
* modify samples/*lynx.bat to use existing TEMP-directory if possible -TD
* modify windows installer to select directory containing SSL DLLs and copy
   them into lynx's application directory -TD
* add oldlynx.bat sample script to windows installer -TD
* use default lynx.lss color scheme with samples/lynx.bat -TD
* modify windows installers to use static libraries for pdcurses and slang,
   because the dll for the latter is much larger than the rest of lynx.
   Even with this change, lynx.exe is 50% larger when using slang than with
   pdcurses -TD
* rename test-package for ".rpm" to "lynx-dev" for consistency with ".deb" -TD
* improve samples/lynx.bat by using location of script rather than current
   directory -loto1992 AT inbox DOT ru ("Smuggler")
* permanently enable MISC_EXP feature -TD
* remove several obsolete ifdefs: DGUX, DGUX_OLD, HP_TERMINAL,
   REVERSE_CLEAR_SCREEN_PROBLEM, SHORTENED_RBIND, SLANG_MBCS_HACK, SNAKE -TD
* improve logic in HTCopy used to limit reads based on content-length to
   take into account server headers which extend past the first block read
   (report/test-case by Dick Wesseling) -TD
* permanently enable EXP_HTTP_HEADERS feature -TD
* modify color-style hashing to check for collisions (reported by TG, Russell
   Bell) -TD
* add PREFERRED_CONTENT_TYPE defaulting to text/plain and options-menu to
   replace an assumption in HTMIMEConvert that everything is text/html.
   Since most servers provide a valid Content-Type for HTML, and are more likely
   to omit it for files lacking a known suffix, defaulting to text/plain is a
   better choice -TD
* remove dead-code for OMIT_SCN_KEEPING -TD
* remove dead/unreachable pretty-source code in HTML.c, noticed because
   it complicates hashing -TD
* improve hashing for anchors and styles by using a more suitable hash-table
   size -TD
* add a note in lynx.cfg telling how to remove a default key-mapping -TD
* modify "=" command to make it possible to disable margins for the URL string,
   by first disabling wrapping using "|" -TD
* several fixes for Windows version -TH
   + fix an abnormal terminate when pressing 'd'(download) on no action button.
   + work around incompatibility in move() between POSIX and Windows.
     ref: https://www.securecoding.cert.org/confluence/display/c/FIO10-C.+Take+care+when+using+the+rename%28%29+function
   + fix limit-check for SJIS which prevented showing a show long title in the
     title bar on Windows environment.
   + fix problem with PDCurses when wrapping lines.

     This problem occurs only with some combinations of source and destination
     screen size.
     For example: 80x25 -> 90x20
   + including some code clean up
* improve consistency in help-files discussing line-edit keymaps (prompted by
   Debian #888391) -TD
* additional fixes to work with LibreSSL on OpenBSD 6.2 -TD
* build-fixes for OpenSSL 1.1.0 versus 1.0.0 (patch by Quentin Minster).
* modify configure script to make a quirk of NetBSD's make-program less
   noticeable -TD
* modify configure script to work around pkgsrc's misconfiguration of shared
   libraries -TD
* modify po/makefile.inn to ensure the temporary files have distinct names
   to avoid problem with "make -j8" (Debian #890811) -TD
* update makefile/batch-scripts to allow building with newer Visual Studio
   versions, e.g., 2010, 2012, so that a 64-bit executable can be built -TD
