New features

New features (some are compile-time options):

• add internal URL "LYNXEDITMAP:", which is (like "LYNXKEYMAP:") generated, making that the primary page for field-editing help
• make nsl-fork work for the DNS lookup using getaddrinfo, i.e., for IPv6 configurations
• revise nsl-fork logic for passing addrinfo and hostent data back to eliminate fixed limit on the number of records to return
• correct formatting of large file-sizes in directory listing
• modify finish_ExtEditForm to eliminate wrapping when an edited line is longer than MAX_LINE. The user is still offered the choice of wrapping to the displayed size of a TEXTAREA, but if declined, the TEXTAREA's content will not be wrapped
• add "submit" and "reset" commands
• add "pwd" command, to show current working directory in the statusline
• modify handling of "set" in -cmd_script option to try both cfg-file and rc-file settings
• modify LYConvertToURL to use LYTildeExpand for Unix, and further modify LYTildeExpand to lookup given user's home directory, thereby making commands such as "g ~root/tmp" work as expected
• add option -unique-urls
• add -list_inline option, which modifies -dump output to put links inline with the text rather than in a list at the end of the dump
• change default behavior:
  • change default for --enable-addrlist-page configure option to enabled
  • change #define's for addrlist-page and alt-bindings to reflect their non-experimental status
  • promote some experimental options to normal, tidy up related EXP_xxx vs USE_xxx symbols:
    • EXP_ASCII_CTYPES is now USE_ASCII_CTYPES
    • EXP_JUSTIFY_ELTS is now USE_JUSTIFY_ELTS
    • EXP_CHARSET_CHOICE is now USE_CHARSET_CHOICE
  • The scrollbar, progressbar, sessions and session-cache options are now enabled by default.
  • change compiled-in default for SYSLOG_REQUESTED_URLS to false
  • make DONT_TRACK_INTERNAL_LINKS logic configurable via lynx.cfg as TRACK_INTERNAL_LINKS; the configure script now sets the default value
  • change URL for HELPFILE in lynx.cfg, etc., to omit version-specifics

Other enhancements

Configure script

These changes were made to the configure script:

• add configure option --with-cfg-path and environment variables LYNX_CFG_PATH to provide search-list capability for the ".cfg" and ".lss" files
• fix a check in configure-script for openssl subdirectory in includes. It happened to work in most cases due to a spurious blank in the pkg-config file; this was removed recently, e.g., for Fedora20
• update configure script to add --datarootdir option, which changes the default for man-page from /usr/lib to /usr/share
• modify configure check for sizeof(time_t), sizeof(off_t) to help recover if it is run in a deficient environment such as busybox
• check for tinfo library, which may be present
• add check for 'make' programs ${MAKEFLAGS} versus ${MFLAGS}, for recursive operation.
• add configure --with-textdomain option to allow overriding the "lynx" NLS textdomain, to help ensure that Lynx's build-script does not conflict with alternative packages
• use AC_ARG_PROGRAM in configure script, to support --program-suffix, etc., to help with packaging
• correct typo in configure --enable-gnutls-compat option, which sometimes made it enabled as a side-effect of setting --with-gnutls
• add configure option --enable-wais, for test-compiles with freeWAIS
• add workaround in CF_SSL configure macro for broken openssl pkg-config script on Redhat, CentOS
• add configure option --disable-rpath-hack
• modify configure script to check if linkage for bzlib and zlib succeeded, before defining symbol which makes the compiler uses these libraries

SSL support

These improvements were made to SSL support:

• add GNUTLS call to enable SNI (Server Name Indication) extension
• apply openssl patch from openSUSE package for Lynx to modify the SSL options to omit the SSLv2 and compression features; apply analogous changes to tidytls.c interface.
• improve warning message for GNUTLS_CERT_SIGNER_NOT_FOUND
• check for SSL error when reading response from "GET". This incidentally exposes a longstanding bug in GNUTLS.
• correct check for return-value from gnutls_certificate_verify_peers2(), which in conjunction with unclean internals of gnutls caused caused some sites to be treated as if they were version-1 X.509 CAs

HTML interpretation

These improvements were made to HTML interpretation:

• modify <address> tag to treat it like <p> when used within a list
• modify the INFO page, normally bound to "=", to show decoded strings for URLs, e.g., which use %xy hexadecimal encoding. The decoded strings are shown on the line following the encoded URLs if the strings are different. Also if display-charset is UTF-8, modify -dump "References" URLs to show the corresponding decoded strings for consistency with the text which is already in UTF-8. Other URLs such as that shown in the status area are shown in encoded form per previous discussion which recommending doing this to address phishing attempts
• amend implementation of "readonly" attribute from 2.8.7dev.10 to distinguish it from "disabled"
• simplify file-URLs shown in reference list of -dump by trimming unnecessary "localhost", e.g.,

  file://localhost/XXX
  

  becomes

  file:///XXX
  

• modify default case for HTLoadGopher() to use the file's suffix to obtain a MIME mapping rather than always storing unknown types to disk
• modify print_wwwfile_to_fd() to add field values to the printed form
• allow IPv6 addresses without "http://" prefix
• use HTParsePort() in a few places, e.g., HTFinger.c, to allow for IPv6 addresses with colons
• limit downloaded files by Content-Length if any, to match behavior of IE, Firefox and some other browsers; this is not addressed in RFC 2616
• modify HTLoadDocument() to not retain a cached document if user is explicitly doing a refresh. This fixes the case for a #fragment url, which was otherwise treated as the same as the address without the #fragment
• modify HTLoad() to discard charset information before reloading a document, in case the server changes the content-type information between loads
• ensure that button/input tags have a value for display, in case the tag is improperly terminated
• modify comparison for splitting lines to allow for long preformatted lines, e.g., using  's to not wrap when the line-wrap mode is disabled
• add optional support for IDNA using GNU libidn

Character sets

These improvements were makde to character sets and display:

• modify the LOCALE_CHARSET feature to provide a default value for the ASSUMED_CHARSET feature aka "display-charset"
• ignore LEFT-TO-RIGHT-MARK (U+200E) in HTML files
• modify check in HText_endForm() when a form contains only a single input field, to allow a return in any text-like field other than textarea to cause the form to be submitted
• use ASCII apostrophe for 7-bit approximation to U+02bd as well
• use ASCII apostrophe 0x27 for 7-bit approximation to Unicode apostrophe U+02bc
• add U+0218, U+0219, U+021a, and U+021b to 0x53, 0x73, 0x54, and 0x74, respectively, for Romanian s/t with cedilla in def7_uni.tbl
• add HTML5_CHARSETS feature, which allows the user to choose whether to interpret pages without an explicit charset according to the HTML5 "compatibility" feature

Color-style

These improvements were made to color-style:

• add -default-colors command-line option to allow toggling the state of the DEFAULT_COLORS setting from lynx.cfg
• add on/off toggles to options menu for the color-style and default-colors features, to help deal with packages which enable default colors without adjusting the color-style settings to avoid having yellow text on a white background
• modify configuration of COLOR_STYLE value in lynx.cfg, allowing multiple filenames to be specified and providing those as choices in the O'ptions menu
• improve color-style simulation of old color scheme by coloring input fields with color #5

User interaction

These improvements were made for interaction with the user:

• extend ^X-e editing of textarea's to include single-line fields
• modify LYgetstr, making it call revised function LYgetBString which handles bstring's, and allows editing fields which can grow without fixed buffer limits. In particular, forms all use the same calls, which means that their result is no longer limited by MAX_LINE. Replaced most LYgetStr calls with LYgetBString, except for LYMail.c and LYNews.c since those do use LYgetStr's limits as it was designed. Other calls generally did not need those limits.
• ask for filesize when downloading via ftp, to use this in the read-progress ETA
• provide a way to substitute parameters in URLs for jumpfiles
• extend the "Bad HTML" warning feature to -dump option when the -stderr option is also set
• revise dired-mode's modify_tagged() function, correcting and extending the source-paths to validate against the target path. Before, lynx's current working directory was used to validate against target path, i.e., when moving all tagged files to a new location. Lynx's check to ensure that source/target paths are distinct prevented users from moving tagged files to the current directory
• remove check from 2.8.5dev.11 which prevents user from moving a directory in dired unless the external program "mv" is provided
• apply overlooked patch from pre-2.8.5, makes RMDIR_PATH configurable
• modify option -dump so it is parsed in the first pass, using that to suppress requirement for lss file if lynx is used only to dump output

Other programs

These changes improve interaction with other programs:

• update/improve blat mailer support:
  • document blat/blatj usage in lynx.cfg
  • update command-line syntax for the blat mailer, to work with blat 2.6.2
  • change default in makelynx.bat to assume blat rather than blatj, because the latter does not provide a way to authenticate user/password on a mail server
  • modify blat/blatj configuration so that support for both is compiled-in for DOSPATH configurations. Add "-altblat" option to select blat vs blatj. Define USE_ALT_BLAT_MAILER to specify which is the default
  • modified quoting for parameter values passed to blat mailer to ensure that it handles embedded blanks

Cookies

These changes improve cookie support:

• add/use WriteStreamTitle(), to provide doctype for cookie-jar page, used to help validate the page
• improve readability of cookie-jar page by showing the unescaped cookie values, other minor formatting changes
• modify cookie domain-matching to accommodate RFC 6265, which states that a leading dot on a domain attribute should be discarded

Debugging

These improvements were made to debug/traces:

• add traces for builtin dired operations

Scripting

These improvements were made to scripting/logging:

• bug-fixes only

Other

Here are other general improvements:

• modify lkcstring_to_lkc() to accept hex/octal values, allowing those in the KEYMAP configuration as suggested by the commented lines in lynx.cfg
• add PERSONAL_MAIL_NAME to options menu and .lynxrc
• add EXTERNAL_MENU feature to lynx.cfg, which allows the user to customize the menu-entry shown, e.g., to suppress the display of the URL

Sample files

There are new/improved sample files:

• add samples/oldlynx.bat to demonstrate how to use non-color-style
• modify samples/lynx-demo.cfg to suppress external file-utilities, since the intent is to make the installer work standalone, but allow extension
• install the sample-files in the dpkg test-script

New ports:

• none
  (it seems to run everywhere, but there are a few possibilities)

Improvements to existing ports:

• UNIX:
  • bug-fixes only
• Linux:
  • bug-fixes only
• WIN32:
  • integrate most of the changes from patch in 2.8.6rel.4 package at

    http://lynx-win32-pata.sourceforge.jp/

    • provide toggle between normal/fullscreen
    • ifdef'd changes for FEP.

    • modify makefile.bcb and lynx.rsp to use openssl and intl libraries.
    • add feature ifdef'd with USE_PROGRAM_DIR which adds fallback definitions for pathnames to use the directory of lynx.exe
    • add check for unsafe filenames in DOS/Windows, e.g., those that correspond to a device.
  • improve cross-compiling:
    • add NSIS script, to allow building Windows installer via cross-compiling
    • fixes to configure script and makefiles to work with empty $prefix, e.g., as used in MSYS
    • improve configure check for sleep() for cross-compiling to MinGW
    • modify configure check for inet_addr() for cross-compiling to MinGW
    • add configure check for Win32 flavor of PDCurses when cross-compiling to MinGW using the "--with-screen=pdcurses" option
    • add configure check for windres needed for mingw build if cross-compiling
  • improve/extend native builds
    • protect redefined errno values for Windows port from redefinition warnings when using MinGW build, since the WSAxxx values are what the configuration actually uses
    • change makefile.msc and lynx-slang.iss to use dll for slang
    • use PDCurses "wide" variation in makefile.msc
    • modify makew32.bat and makefile.bcb to use GnuWin32 packages to simplify builds with Borland 5.51 C++ compiler

    • add bzlib to win32 makefile.msc
    • define WIN32_LEAN_AND_MEAN in makefile.msc to accommodate naming conflict in recent Win32 SDKs, which otherwise include winsock.h in windows.h
    • add version-info to LYIcon.rc
    • change Windows default for LYNX_LSS_FILE to not use a directory-path
    • improve DOSPATH-related logic in HomeEnv(), making this work properly with Windows Vista and 7. The feature is needed to read Lynx's bookmarks file from the user's "Personal" shell-folder
    • modify samples/*.bat to work when running in a directory whose pathname contains spaces
    • reduce required privileges for installing in lynx.iss
    • modify the Inno Setup files to show lynx's version numbers. Development and prerelease versions are indicated in the numeric-only versions by prefixing a "10" or "20"
  • modify LYExecv() in LYLocal.c to allow win32 applications to use this function
• VMS:
  • build-fixes only
• Other
  • bug-fixes only

Maintainability

These improvements were made for maintainability and testing:

• update doctype for html documentation to 4.01 strict
• add build/packaging scripts for RPM and DEB, for both native and cross-compiling.
• several fixes for the -find-leaks option, e.g., include LYLeaks.h in a few modules, modify the StrAllocVsprintf function to update the bookkeeping,
• update LYLeaks.c / LYLeaks.h to include the bstring allocation, copy and free functions etc

As well as security-related changes:

• modify convert_to_idna() to check for malformed urls (Debian #594300 reports this as CVE-2010-2810)

And finally:

• A lot of bug fixes
• A lot of documentation changes.
• A lot of dead code removed
