New features (some are compile-time options):
* add session save/restore feature
o bind ^X to toggle view of page showing session information
o add binding for ^U to previous-document (outside of
line-editing).
o documented command-line options and configuration data
for this feature.
o document -child_relaxed option in Lynx users's guide.
* add -passive-ftp option.
* add -child_relaxed option.
* add "read_timeout" to lynx.cfg, and -read_timeout option to
command-line
* add -show_cfg option.
* add LYNX_HELPFILE environment variable to allow override of
location of the help-file
* add NO_PAUSE setting to lynx.cfg, .lynxrc and Options menu
* implement a LONG_LIST equivalent for ftp, configurable as
FTP_FORMAT
* add XWINDOWS / NON_XWINDOWS environment-variable field to
DOWNLOAD, etc., in lynx.cfg to specify whether a downloader
(printer, etc) is enabled when the X display variable is set
* configure script improvements
o add --with-mime-libdir option to set MIME_LIBDIR in
userdefs.h file
o add --with-destdir configure option to set a default
value for the DESTDIR variable in makefiles, and modified
makefiles to ensure that setting DESTDIR in the top-level
makefile propagates to lower levels
o add --enable-local-docs option to link doc-directory
from help-page
o add --enable-ascii-ctypes option to enable EXP_ASCII_CTYPES
Other enhancements:
* improve SSL support:
o improve X.509 certificate validation This is tested
for OpenSSL, ifdef'd to not break gnutls. Changes:
+ peer certificate is cached, no need to call
SSL_get_peer_certificate() twice
+ support foo.domain:port and [ip.add.re.ss] and
[ip.add.re.ss]:port and [i:p:v:6:ad:dr:es:s] and
[i:p:v:6:ad:dr:es:s]:port
+ add support for checking X.509v3 SubjectAltName
extensions (of type DNS - tested - and IP - untested)
when the X.509 commonName check fails.
+ when displaying a list of failed CNs, change
format from foo:bar:baz to
CN{foo}:CN{bar}:CN{baz}:SAN{DNS=foo}:SAN{IP=1.2.3.4}
so that we know where what comes from (in "Your
recent statusline messages")
+ if the peer certificate can *NOT* be verified,
output a message to the log as well
+ fix a possible use of an uninitialised value
ssl_all_cns
+ output certificate issuer to the logs as well
(so that you can, before entering your online
banking PIN, see if the certificate has been issued
not only _to_ your bank but also _from_ a place
you trust, in case /etc/ssl/certs/ contains a lot
of Root CA certs)
o add support for the X.509 extension subjectAltName
using GNUTLS.
o log SSL/TLS (HTTPS connection) X.509 certificate issuer
information into the "recent statusline messages"
(accessible via the backspace key)
o add TNS SNI support for the OpenSSL configuration
o modify CF_SSL configure macro to check for -ldl needed
for recent OpenSSL versions
o modify CF_SSL configure macro to build with MSYS for
MinGW configuration
o extend configure macros CF_SSL and CF_GNUTLS to check
for pkg-config, using that for the default if the
corresponding openssl or gnutls packages are installed.
o add configure --with-nss-compat option, for building
with NSS library's OpenSSL-compatible interface
o add SSL_CERT_FILE to lynx.cfg
o rewrite strcasecomp_asterisk() to support wildcards as
in RFC 2818
o add --enable-gnutls-compat configure option and associated
files to configure with GNU TLS without its gnutls-openssl
library, whose newer versions are available only under
a restrictive license.
o fix src/tidy_tls.c X509_get_issuer_name to actually
take the issuer DN of the present certificate and not
hope that it is the same as taking the subject DN of the
"next" certificate which may or may not exist.
* improve HTML interpretation:
o update Lynx's tables of HTML attributes to cover (except
for events) the keywords from HTML 4.01
o use RFC-822 encoding for filenames passed via file-upload
forms.
o provide navigation to script-buttons, to make them more
visible, showing their name
o add "Bad HTML messages" to Options menu, letting the
user disable the warning message, write the detailed
messages to the LYNXMESSAGES: status buffer.
o remove "Bad HTML" warning for buttons outside a form,
since those can be inline, according to the HTML 4 DTD
o correct check for default type of HTML BUTTON, which
is "submit". The code treated this as "button".
o implement "readonly" attribute for TEXTAREA and TEXT
fields
o accommodate (in)compatibility "feature" in HTML5 draft
which replaces ISO-8859-1 with Windows-1252, as indicated
here.
o add support for HTML5 rel=author in link.
o modify SGML_write() to check for UCS-2 BOMs, to provide
support for UCS-2 pages.
o modify SGML_write() to check for UTF-8 BOM, using that
as a hint to set the default document charset to UTF-8.
o parse xml processing-instruction to turn on UTF-8
decoding, as well as disable upper/lower case transforming
in source view.
o parse doctype for xhtml, to tell when empty tags such
as "<textarea />" can be discarded
o translate named entities, etc., for "content" field of
refresh-URL.
o add switch -xhtml-parsing and lynx.cfg XHTML_PARSING
setting to control whether the extensions for XHTML 1.0
are used.
o modify Lynx's DTD information to allow it to display
form-related tags that are inline, even without being in
a form as indicated in
http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd
for %inline.forms and %misc.inline.
* improvements to character sets and display:
o improve drawing of menus for multibyte characters by
changing the way the number of fill-characters is computed
in LYpaddstr
o fix some uses of gettext in options menu and info page
where a translated string might contain angle-brackets
or ampersand
o modify popup for externals added in 2.8.4dev.20 to
number the entries if keypad mode is set to one of the
numbered forms
o ie multibyte editing of text-fields.
* improvements to color-style:
o bug-fixes only
* improve interaction with user:
o remove check for -dump option from HTHandleAuthInfo(),
allowing Lynx to -dump or -source NNTP urls
o change the phase during which "-help" option is processed,
to allow it to reflect the configured values of the options
in the help-message
o check if there is piped-in data when starting without
"-" or "-stdin" options, warn about the ignored input
data in that case.
o add ncurses scroll-wheel support, which requires the
extended-mouse configure option of ncurses.
o modify initial active link in download-page to be the
first download action rather than the "help" link whided
in Novice mode.
o make the size of LYNXMESSAGES configurable in lynx.cfg
with STATUS_BUFFER_SIZE
* improve interaction with other programs:
o discard anchor's post_data field in HTLoadDocument()
if Lynx is about to reload a do. That would happen if
the result of the form includes a link back to the form.
Removing the data causes Lynx to prompt the user, e.g.,
Resubmit POST content to
http://localhost/cgi-bin/lynxtest.pl ? (y/n)
to offer the user the choice between revisiting form
or re-POST'ing the data that was on the form
o pass a newline after the start of PRE-section in
HTGopher.c to force the first newline between records to
be seen and cause the lines to split
o add POSITIONAL_EDITOR setting to configure editors
which accept a "+line" parameter
o modify external editing of TEXTAREA to not do
tab-conversion.
o modify behavior of "-nonumbers" option for -dump so it
can be combined with -listonly to obtain a list of the
URLs without reference numbers.
o implement "chunked" transfer-encoding to work with
servers that ignore the version number in HTTP get's
o add an Options menu checkbox to tell if Lynx should
send a user-agent string. Unless the useragent restriction
is set, the default for this checkbox is off, so that
Lynx will not send the string. The corresponding setting,
send_useragent, may be saved to ~/.lynxrc, but normally
is not.
o change default for configure --enable-ascii-ctypes to
true.
o modify exit code when doing a "-dump" to exit with
error if the server returned an error status for the
page.
* improve cookie support:
o modify cookie-writing to not write if no cookies were
read from the file and none are available.
o adapt/extend parsdate.y from tin to improve parsing of
cookie expiration times.
* improvements to debug/traces:
o change initialization of trace file, handing this during
the first part of argument parsing along with -help and
-version, to show steps done for initialization of
presentors, etc
* improvements to scripting/logging:
o bug-fixes only
* other improvements:
o build/install "en" po file so that GNU gettext LANGUAGE
environment variable can find the corresponding English
message file.
o if iconv_open() using transliteration fails, retry
without the transliteration feature.
o improve change for UCSetBoxChars() from 2.8.6dev.16
for EXP_CHARTRANS_AUTOSWITCH which assumed that the
line-drawing character set was always different from the
display character set. If both are US_ASCII for example,
ASCII lines would be drawn, which is not good
o modify scanning of floats from lynx.cfg to allow Lynx
to read POSIX values in non-POSIX locales
o replace BROKEN_PROFTPD and BROKEN_WU_FTPD logic with
configurable list of strings in lynx.cfg, i.e.,
BROKEN_FTP_RETR and BROKEN_FTP_EPSV, and add "spftp/" to
the predefined values for the former.
o modify to handle a special case where the content-type
is given as one of the compressed types, to check if the
address (after stripping the file suffix for that
compression) has a suffix that lynx could present For
example:
http://foo/bar.html.gz
would display the uncompressed "bar.html" rather than
offering to download the file. This also allows one to
add SUFFIX commands to lynx.cfg to display the
corresponding plain files. For example:
SUFFIX:CHANGES.*:text/plain:8bit
SUFFIX:CHANGES:text/plain:8bit
for
http://foo/CHANGES.tmp.gzhttp://foo/CHANGES.gz
o fix ipv6 literal command-line parsing.
o setup locale before writing version-message.
New/improved sample files:
* add sample scripts for configuring MinGW version using Cygwin.
New ports:
* none
(it seems to run everywhere, but there are a few possibilities)
Improvements to existing ports:
* UNIX:
o add definition for _FILE_OFFSET_BITS in CF_LARGEFILE,
needed for Solaris 64-bit compiles.
o modify UCdomap.c to work with Solaris iconv and handle
additional encodings:
+ if "TRANSLIT" feature (an extension of glibc)
does not succeed, retry the call to iconv_open
without "TRANSLIT"
+ add check for any MIME name beginning "iso8859",
mapping to "iso-8859"
+ recognize "eucjp" MIME name as alias for "euc-jp"
+ recognize "pck" MIME name as alias for "shift_jis"
+ recognize "ansi-1251" MIME name as alias for "windows-1251"
o modify parsdate.y to convert between EBCDIC/ASCII to work on z/OS
* Linux:
o bug-fixes only
Improvements for maintainability and testing:
* modify definitions in LYStructs.h for union to cast to a
void* rather than a long, to help with 64-bit ports
* fix some mismatched BOOL vs BOOLEAN from compiler warnings
due to dev.13 change to LYStructs.h
* change a few options such as --enable-locale-charset option
to non-experimental
* free leaks of LYLeaks.c, to make it simpler to check it with
a second tool such as valgrind.
* use off_t rather than long for representing file sizes, e.g.,
when used to print progress messages
* use dtd_util to replace most of HTMLDTD.h and HTMLDTD.c with
source generated from the existing tables in those files
* rename variable defined by CF_PATHSP to PATH_SEPARATOR, use
this consistently to ease use in later autoconf versions
As well as security-related changes:
* modify prompt in LYLoadCGI() from 2.8.6dev.15 to always prompt
user (from FEDORA-2008-9597), and modify compiled-in configuration
default for consistency with other lynx.cfg settings to require
that lynx.cfg be set to permit use of lynxcgi scripts.
* modify logic for reading PERSONAL_EXTENSION_MAP and
PERSONAL_MAILCAP to ensure that they are files that are controlled
only by the user. The default values for these allow lynx to
read configuration information from the user's current directory
at lynx's startup.
* ensure that PERSONAL_EXTENSION_MAP and PERSONAL_MAILCAP are
absolute pathnames, performing tilde expansion as needed.
Pathnames that are not given in absolute form will be sought
under the user's home directory as if they began with "~/".
* ensure that the configured values for GLOBAL_EXTENSION_MAP
and GLOBAL_MAILCAP are absolute pathnames.
And finally:
* A lot of bug fixes
* A lot of documentation changes.
* A lot of dead code removed
New features (some are compile-time options):
* INFO and Options pages are laid out properly for multibyte locales,
accounting for character widths.
* change configure option default for --enable-justify-elts to true.
Change default for JUSTIFY to "false".
* add PREFERRED_ENCODING to lynx.cfg, along with an options-menu
selection for this, to set "Accept-Encoding:" string
* add PREFERRED_MEDIA_TYPES to lynx.cfg, corresponding to the option for
HTFilterPresentations(). A minimal set of media types is used by
default, though the old behavior can be selected
* add -nonumbers option, which modifies the output of -dump to suppress
the link-numbering
* add -listonly option, which modifies the output of -dump to show only
the list of links
* add -syslog-urls option and lynx.cfg settings (SYSLOG_TEXT,
SYSLOG_REQUESTED_URLS) to allow syslog'ing of URLs to be optional.
This cannot be set from the options menu
* the -version option shows the version of ncurses, curses, etc., from
runtime data when available.
* add -notitle option to suppress title line and following blank line to
maximize screen use for small displays
* add -nomargins option to suppress left/right margins to maximize
screen use for small displays
* add NO_MARGINS and NO_TITLE to lynx.cfg
* add NESTED_TABLES setting to lynx.cfg to allow site override of the
built-in default
* add DEFAULT_COLORS item to lynx.cfg to allow disabling the default
colors feature at runtime, allowing better matching of old color
scheme via a script
* add -stderr option to write error messages when doing a -dump -or
-source. Normally these are written to the status line but that does
not exist when dumping to standard output
* add configure --enable-largefile / --disable-largefile options.
* add --enable-widec configure option to allow building lynx without
wide character support using ncursesw, to accommodate users with older
releases of ncurses
Other enhancements:
* improve SSL support:
* updated README.sslcerts
* update CF_GNUTLS macro to look for -lgnutls-openssl as well as
the older -lgnutls-extra library
* modify HTLoadHTTP() to interpret leading asterisks in common name
fields as wildcards
* suppress OpenSSL URL from version message if it happens to be
built using GNU TLS (or other libraries which happen to define
symbols to pretend they are OpenSSL).
* improve HTML interpretation:
* fix function, which was checking for the absence only of some
nonstandard encodings (8bit, 7bit, binary) rather than for the
presence of the encodings as specified in RFC 2068 (gzip,
compress, etc). This makes lynx able to view a site which puts
the charset as the Content-Type
* add "deflate" to the encoding types which lynx implements. This
consists of several parts
* adapted logic from w3m's inflate.c to construct an internal
"deflate" decompressor. Tested this with
http://carsten.codimi.de/gzip.yaws/
* add "deflate" to the options menu.
* modify logic that builds "Accept-Encoding" value to omit
encodings which have no external decompressor associated.
The effect of this change is to allow lynx to behave as it
did before adding the (possibly incomplete) "inflate"
support.
* add INFLATE_PATH to lynx.cfg, to optionally specify an
external program which can be used to decompress deflated
files. For testing, a shell script using w3m's utility,
e.g., /usr/lib/w3m/inflate, sufficed. NOTE: As currently
implemented, lynx requires the external decompression
programs to be specified even if it can decompress using
library calls.
* use ".zz" for suffix of downloaded (but not inflated)
deflated files, mapped to application/deflate and
application/x-deflate.
* modify source-view toggle to keep the current anchor visible.
Toggling source view may change the line number on which the
anchor is found, requiring some adjustment. This feature is
implemented only for source cached pages
* fixes to source-view of ftp:// and file:// URLs, i.e., eliminate
redundant PRE's, add DOCTYPE and meta tags
* correct parsing of embedded URLs which have parameters but no
path, e.g., base
http://wj55.org/Minutes.php
and embedded
?date_meeting=2004-08-31
* add presentation type for application/xml and text/xml mime types
as per
http://www.w3.org/TR/xhtml-media-types/http://www.w3.org/TR/2002/NOTE-xhtml-media-types-20020801
which states that they may be used, though application/xhtml+xml
is the preferred media type
* add presentation type for application/xhtml+xml mime type as per
RFC 3236
* add presentation for text/css, to allow browsing ".css" files
* force a newline in HTML_end_element() after a </pre>, which
causes lines containing only whitespace before the </pre> to
display a new line, rather than putting that whitespace before
text that follows the </pre>
* following a link consisting of a "#" fragment will move the
cursor to the link containing the target rather than simply
ensuring that it is visible
* improvements to character sets and display:
* new message files for localization: rw.po, vi.po
* updated message files for localization: cs.po, da.po, de.po,
et.po, fr.po, hu.po, nl.po, pt_BR.po, sv.po, tr.po
* use puts() rather than printf() in some messages to avoid chance
of "%" in the translation
* modify HTConfirmCookie() to ensure the translator's note is
copied into the lynx.pot file, by adding a gettext("Y/N/A/V")
call after the comment
* improve layout of options-menu and info-page for multibyte
character sets by computing the extent of the labels. This works
only for wide-character curses.
* add ISO-8859-13 and ISO-8859-14 chrtrans tables, revise
ISO-8859-10 based on
http://czyborra.com/charsets/iso8859.html
Change display name for ISO-8859-10 to indicate the region
* improve checking if the current character set does not match the
character set inferred from the locale. This reduces the number
of cases where line-drawing in the options menu does not work
* improve recovery when a charset is found that cannot be
translated. Before this change, the charset was not stripped from
the format string, e.g.,
text/html; charset=big5
and since there would be no match for the format, lynx would
offer to simply download the page (if interactive), or refuse to
format (for dumps). Although the content of the page is unusable,
the user can still navigate the page using the links which may be
there
* modify logic for locale_charset configuration variable so it is
not modified simply by saving the .lynxrc while in running in a
non-locale configuration. That does not alter the display charset
used by lynx
* improve workaround for line-drawing characters with
font-switching by checking if the loaded font has line-drawing
characters in the same positions as the terminal description,
rather than simply ignoring line-drawing when the codeset differs
* workaround for codepage support on OS/2 by changing the effect of
unctrl(). Add/use new preferred function use_legacy_coding() to
ncurses which provides the same effect with the wide-character
ncursesw
* improve def7_uni.tbl substitutions for the symbols beginning at
U+2600
* add experimental option --enable-japanese-utf8 for using libiconv
for Japanese and UTF-8
* improvements to color-style:
* change configure script --enable-color-style so it is enabled by
default
* add COLOR_STYLE setting to lynx.cfg
* change default initialization of color-style code when no lss
file is given to simulate the non-color-style code. There are
some visual differences, e.g., links that contain a mixture of
styles will display with mixed colors, but overall the visual
effect matches the non-color-style code well enough to change the
default configuration. If an empty string is given for the lss
filename, this is treated as an empty style file, and lynx will
not use its built-in default color style. To make the behavior
easier to diagnose, lynx will now exit with an error if it cannot
find the lss file.
* improve interaction with user:
* highlight the target and pause for 20 milliseconds when selecting
a link with the mouse
* modify behavior when user attempts to toggle a radiobutton off,
to make the message that one radio button must be selected only
in novice mode
* modify column limits, allowing text to be written to the last
column on the screen. This allows users to view text which is
formatted for 80 columns without the last character of each line
wrapping to the next line
* prompt user, displaying the command that would be executed, to
confirm that it should be. This makes it easier to notice when a
local program would be run by activating a lynxcgi link. This is
not done in advanced mode, since the URL is already visible in
the status line
* modify HTSaveAndExecute() to check first for result from
HTFileSuffix() before choosing between BIN_SUFFIX and
HTML_SUFFIX. This allows the PDF viewer on OS X to get the proper
suffix (.pdf) rather than .bin
* add check for failure to write to disk, e.g., on disk full, and
report error condition via HTAlert()
* modify suggested_filename() to strip bzip2's ".bz2" suffixes as
well as ".zz" suffixes
* modify INFO-page to list the rendered size in bytes if the
Content-Length is not available
* print the contents of image maps, if any, at the end of a dump
* command-line options that toggle or set a boolean now accept
"true" and "false" strings.
* improve interaction with other programs:
* strip special characters such as '%' from parameters passed to
external programs for EXTERNAL mechanism on Windows platform.
This is ifdef'd with WIN_EX
* improve cookie support:
* modify HTConfirmCookie() and statusline() to allow cookie prompt
message in Japanese to not be truncated when using wide-curses
* make the maximum number of cookies configurable in lynx.cfg,
added MAX_COOKIES_DOMAIN, MAX_COOKIES_GLOBAL and
MAX_COOKIES_BUFFER
* improvements to debug/traces:
* use symbol USE_VERTRACE in HTUtils.h to allow makefiles that do
not use the configure script to turn on the equivalent --enable
vertrace feature
* improvements to scripting/logging:
* make "lynx -version" work in the absence of ".cfg" or ".lss"
files
* modify print_wwwfile_to_fd() and print_crawl_to_fd() to ensure
that no trailing blanks are written in a -dump, etc.
* correct parsing of "key 0xNN" lines in command-scripts, had
omitted a "!" to invert a check
* modify initialization so that
cat options.txt | lynx -
will allow interactive use
* other improvements:
* modify logic for -dump so it can dump all pages listed on the
command line
* lynx accepts multiple URLs on the command line; all are added to
G)oto history. Documented this in manpage
* add (ifdef'd with EXP_HTTP_HEADERS) code to display the full text
of the HTTP headers in the INFO page.
* modify treatment of symbolic links for ftp-URLs to show the link
target, as with the local directory editor
* correct sort-order of local directory listing, using the target
of a symbolic link to determine whether it is grouped with files
or directories
* modified mailcap command and testcommand substitutions to provide
for running the testcommand's after program initialization
* read user's ".newsauth" file for news-server authentication
information
* escape "From " when it appears in a page which is mailed, to
avoid confusing mail clients
* add "Anonymous FTP Password" to Options menu, to allow user to
override use of personal email address as the anonymous ftp
password
New/improved sample files:
* add script samples/oldlynx, which gives the non-color-style scheme
using an executable built for color-style
* add scripts/tbl2html.pl, which can be used to generate test pages for
the charsets from src/chrtrans/*.tbl
* add test/special_urls.html
* modify ".lss" files to work equally well on terminals setup with white
text on black background, or the reverse. This also required fixing a
few places in LYsubwindow() and curses_w_style() to make window
backgrounds use the colors given in the ".lss" default- and
normal-colors lines
* make ".lss" example files somewhat readable by modifying parser to
remove blanks from the color description lines and modifying the
example files to use this feature
New ports:
* none
(it seems to run everywhere, but there are a few possibilities)
Improvements to existing ports:
* UNIX:
* improve configure script macro CF_XOPEN_SOURCE, ensuring that
_POSIX_C_SOURCE is defined with a value.
* revise configure script check whether _POSIX_C_SOURCE should be
defined, taking into account the _POSIX_SOURCE definition
* Linux:
* add codepage 857 (DOSTurkish), since console-tools package
provides a suitable font
* update Linux console font support to use console-tools package.
The configure script checks for consolechars and setfont programs
(must find at least one). The corresponding SETFONT_PATH can be
set in lynx.cfg to provide a choice between the two
* modify configure script to check for Intel compiler 8.0 (and
9.0).
* some others [stripped]
Improvements for maintainability and testing:
* remove macros such as ARGS1, NOPARM which supported K&R compilers
* make ANSI C required, drop support for K&R C.
* add scripts/indent.sh, use this to reindent C source files
* add tags rules to makefile.in's
* modify makefile.in to ensure that scripts are prefixed with $(SHELL),
in case packager has stripped executable permissions from scripts,
e.g., by using CVS
* modify configure script and makefiles to allow cross-compiling
* add --with-system-type option to configure script to simplify testing
the case-statements involving $host_os
* change configure script to put the ".cfg" and ".lss" files by default
in the --sysconfdir, e.g., $prefix/etc, and the help-files in lynx_doc
and lynx_help directories under --datadir, e.g.,
$prefix/share/lynx_doc, $prefix/share/lynx_doc. To obtain the old
behavior, use configure --sysconfdir=/usr/local/lib
--datadir=/usr/local/lib
* add configure options --with-cfg-file and --with-lss-file to allow one
to specify the names and paths of the default configuration and
color-style files
* filter out obsolete URLs from the customizations saved during install
of lynx.cfg
* rename test/iso8859-1.html and test/iso88592.html to
test/iso-8859-1.html and test/isoi-8859-2.html, corresponding to the
proper MIME names to simplify test-scripts
* update test/iso8859-1.html (minor fixes) from
http://www.ramsch.org/martin/uni/fmi-hp/iso8859-1.html
* applied lynx's changes to updated files from ftp.unicode.org to take
advantage of less restrictive copyright
As well as security-related changes:
* eliminate fixed-size buffers in HTrjis() and related functions to
avoid potential buffer overflow in nntp pages
* eliminate fixed-size buffers in LYExpandHostForURL() to guard against
buffer overflow resulting from too-long domain prefix/suffix data from
lynx.cfg
* reduce TRST_MAXROWSPAN and TRST_MAXCOLSPAN to 200, which is more
plausible than 10000 by 1000.
* limit TEXTAREA columns to the screen width, and rows to 3 times the
screen height.
And finally:
* A lot of bug fixes
* A lot of documentation changes.
* A lot of dead code removed
* file-upload supported
* support for bzip2 compression
* performance improved
* improved SSL support
* improvements to color-style
* better interaction with user
* improved cookie support
* correct inverted logic of restrictions table which made "-restrict=default"
provide incorrect values for several items. This was broken in 2.8.4dev.19
(reported by Jeff Long <long@ukans.edu> and RobertM <robm@bob.bofh.org>) -TD
* correct check for calling endwin() to allow for curses implementations
without newterm (report/patch by Brett Lymn).
an abridged change log back to 2.8.4dev19 (lynx-current, which see).
Only entries deemed likely to be visible to the user are reproduced
here. Code clean-ups, reverted interim changes, and changes that would
not affect NetBSD hosts were ommitted. Please see the CHANGES file in
the archive or on the web for a complete list.
Also, by popular demand, make native curses the default (ncurses and
libslang are still build-time options). The color scheme for native
curses under a NetBSD 1.5.* xterm is nearly the same as the libslang
version.
2001-07-10 (2.8.4pre.4)
* correct order of checks for wrapping in www_search_forward() and
www_search_backward(), which would allow an infinite loop if there were no
anchors on the current page (report by Frederic L W Meunier) -TD
* add a missing chunk to reverted change of SGML_character()
2001-07-07 (2.8.4pre.3)
* review/add descriptions of new command-line options in lynx.man, lynx.hlp and
Lynx_users_guide.html -TD
* update da.po, ja.po, ru.po, sv.po from
http://www.iro.umontreal.ca/contrib/po/maint/lynx/
(report by JS) -TD
* add command-line option -curses-pads which can be used to disable the
left/right scrolling logic. This is used for testing, e.g., the repaint
bug reported below -TD
* remove logic in lynx_force_repaint() which reset the window background, since
it does not work with the logic used to implement left/right scrolling.
Retested older versions of ncurses and did not find a case where this was
needed after all (report by IZ) -TD
* add -trim_input_fields command-line option and corresponding
TRIM_INPUT_FIELDS to lynx.cfg to suppress trimming of TEXT and TEXTAREA
fields in forms. This does not retain trailing blank lines in a TEXTAREA;
more work would be needed to do that (reported by VH, most browsers appear to
retain trailing blanks) -TD
* modify parsing of "<script>...</script>" to allow "<!-- ... -->" comments
in SGML_character(). Though the HTML 4.0 spec is fairly clear, other
browsers (and some webpages) assume that "</" does not have to be escaped
when it appears in a script which is commented to avoid confusion with older
browsers. This change doesn't ensure that the comment is at the beginning
of a line, since that's awkward to do with SGML_character(), and also leaves
the script in a comment which works for lynx since lynx does not interpret
it anyway -TD
* modify parse_attributes() in LYStyle.c to allow video attributes such as bold
and reverse to be combined with colors, used this to debug problem with
<script> and comment -TD
* improve logic for nested-tables to handle cases such as www.tin.org -IZ
TRST ignores the horizontal alignment *inside* a multi-line cell of a table.
This limitation, in conjunction with the nested-tables modifications does not
work well when text with a horizontal alignment (e.g., <ul>) is put in a
table cell. This patch introduces a *limited* logic to take this info into
account. It should work OK as far as the last non-empty line of the cell is
ended by a "line-end" command, not by a </td> (this is often the case with
contents using horizontal formatting).
* updated URLs for ncurses (report by DK) -TD
* updated samples/bright-blue.lss -IZ
* update/extend lists in lynx_help_main.html -Frederic L W Meunier
* add note about lynx.cfg mouse and color configuration to user's guide -PW
* document -cmd_log and -cmd_script options in user's guide (Michael Warner).
2001-06-02 (2.8.4dev.21)
* regenerated lynx.pot and resync'd the .po files against it with msgmerge,
formatted to 132 columns to minimize line-breaks, for ease of comparison -TD
* change lynx.cfg entry for COLOR #6 to brightred/black, which is what
Slackware uses, to make links more visible -TD
* add checks for potential buffer overflow in increment_tagged_htline() -TD
* consolidate scattered calls to editor with function edit_temporary_file(),
which fixes terminal modes when editing TEXTAREA -TD
* modify LYisNonAlnumKeyname(), etc., using new functions LYindex2MBM() and
LBMBM2index() so that it should work with EBCDIC, as well as similar case of
translation in LYBookmarks.c which assume that there are no gaps in the
coding for the alphabet -TD
* workaround in lynx_nl2crlf() for ncurses, which did not refrain from using
cursor-down if it was set to a newline when nonl() was specified -TD
* replace permissions[] array in LYLocal.c because cygwin (mis)implements the
S_xxx values as a function -TD
* add ENABLE_LYNXRC setting to lynx.cfg, which allows one to modify the list
of values which are visible on the O'ptions form which can be saved to the
.lynxrc file -TD
* check the width of entries displayed by LYOptions.c non-forms
boolean_choice(), to pad shorter ones with spaces -TD
* change type of LYMultiBookmarks to integer, combine with LYMBMAdvanced, to
use enumMultiBookmarks to set it, making its configuration more easily
table-driven -TD
* make the style of menu border/bg/entry/number/active-entry and scroll
indicator settable -IZ
The names in lynx.lss are
menu.frame menu.bg menu.n menu.entry menu.active menu.sb
* modify cookie path prefix-comparison to ignore a trailing slash, e.g.,
/group/sftvnews/ versus /group/sftvnews (workaround for LV visiting
http://groups.yahoo.com/group/sftvnews) -TD
* cookie path= should be a prefix of the request-URI path, so do not truncate
request-URI path in LYSetCookie() [we got mistaken "invalid cookie path=..."
prompt in some cases previously] -LP
* parameterized the logic around URL_edit_history to add MAIL_edit_history,
used to store addresses for Printing Options, mail file to user (request by
LV) -TD
* check, fix minor problems with some .po files based on check_po script
(mentioned on mutt-dev mailing list by Bjorn Jacke <bjacke@suse.de>) -TD
* check width in LYpaddstr(), truncate the string if needed. This fixes a
case where items in very wide popup menus would wrap, e.g., the EXTERN_LINK
menu -TD
* combine checks for useragent into one function LYCheckUserAgent() -TD
* add runtime toggle for EXP_NESTED_TABLES, bind this to "~" (see www.tin.org
for comparison) -TD
* regenerate ja.po from lynx-2.8.3rel1.ja.po using gettext 0.10.37 and libiconv
1.6.1 (updated by Masayuki Hatta <mhatta@po.airs.net>)
* changed -DNCURSES in DOS makefile to -DPDCURSES -TD
* improve definition of CTRACE, making it an expression again as it was before
dev.20 -PG
* move logic for cookie_domain_flag_set() out of LYReadCFG.c into LYCookie.c
rewriting it to make it table-driven, where it is now shared with LYrcFile.c
-TD
* rewrote LYrcFile.c, making it table-driven as is LYReadCFG.c -TD
* reviewed/corrected several pointer-mismatches in PARSE_xxx() macro usage -TD
* corrected return-types of several functions in LYLocal.c, which were given as
BOOLEAN though they return a signed integer -TD
* add DIRED support to makefile.bcb -TD
* filter the list of mime types sent in "Accept:" header for GET, to eliminate
repeated or shadowed types, using new function HTFilterPresentations()
(addresses Debian bug report #41594) -TD
* fix several typos in Lynx help-files -LV
* enable scroll indicators on the menus - shown if there is a part of menu
before/after the visible area -IZ
* modify the context-sensitive mouse-menu, making it easier to to configure by
reorganizing the tables used to generate the popup menu -IZ
* correct a couple of places in form_getstr() when keys were "generated"
instead of actions, which broke mouse-navigation in input fields -IZ
* fix return value of Stbl_finishTABLE(), retesting curpos whose value may have
been altered, e.g,. in split_line(), causing a cell to overflow to the right
of the visible area (even if line wrap is requested) -IZ
* change the logic of -display-charset: before it was sometimes descriptive
(here is the charset, behave as if it was used for display), sometimes
prescriptive (make the display to use charset if you can). Now it is only
descriptive. One is forced to use the 'O'ptions to manually load a different
font -IZ
* move $(DEFS) and $(CHARSET_DEFS) into $(CPP_OPTS) in src/makefile.in -TD
* renamed -blink_is_boldbg command-line option to -blink, corrected ifdef's -TD
* implement -blink_is_boldbg option for OS/2 EMX and ncurses, then integrated
some ifdef's to merge with equivalent slang code -IZ
* rewrote hardcoded if/then/else chains in handle_LYK_SHIFT_LEFT()
handle_LYK_SHIFT_RIGHT() to repeat_to_delta() function -TD
* implement a key-accelerator for shift-left/right commands, i.e., repeating
the shift command increases the amount by which the screen is shifted -IZ
* modify ifdef in handle_LYK_LINEWRAP_TOGGLE() to use popup menus for each
configuration rather than limit it only to mouse-supported ones such as
ncurses or PDCurses -TD
* changes to left/right scrolling to limit its effect to tables (IZ):
+ rename LYlineWrap variable (used to denote the column at which content is
wrapped) to LYwideLines (used to denote the opposite sense: true if
wrapping is disabled).
+ add global variable LYtableCols to control the column-limit for tables.
The two variables LYLineWrap and LYtableCols have the same effect as did
altering LYlineWrap and LYcols, but are limited to table layout.
+ modify handle_LYK_LINEWRAP_TOGGLE(), use a popup menu to set LYwideLines
and LYtableCols. The latter is set to a positive integer, in units of
1/12 of the physical screen width.
+ modify GridText.c, replacing LYcols with new macros DISPLAY_COLS and
WRAP_COLS.
+ keep scrollbar on the right margin of the screen when the contents are
shifted left or right.
* modify makefile.bcb, add (tested) commented-out lines for building with
color-styles -TD
* modify makefile.msc and makefile.bcb, add (tested) commented-out lines for
building with winsock2 -TD
* add a configure check for napms(), use this if available to support subsecond
delay times for INFOSECS, MESSAGESECS, ALERTSECS -TD
* rewrote www_user_search() to support both forward and backward search.
Bound backward-search to 'N' -TD
* split-out anchor_has_target() and link_has_target() to separate the search
2001-04-01 (2.8.4dev.20)
* rename KEYMAP 'EXTERN' to 'EXTERN_LINK', adding 'EXTERN_PAGE'. Existing
keymaps should work since 'EXTERN_LINK' matches first. EXTERN_PAGE runs the
external command on the current page. Map comma (,) to EXTERN_PAGE -TD
* modify LYExtern.c to recognize if more than one EXTERN command has been
defined in lynx.cfg for a given name, and allow the user to select one
command from a popup menu -TD
* split-out code that opens lynx.cfg and lynx.lss as LYOpenCFG() function,
making that check if the given pathname is absolute. If not, it attempts
to look in the same directory as the parent file (when processing includes),
or the directory of the default config file -TD
* replace some explicit "r", "w", and "a+" fopen modes with TXT_R, TXT_W and
TXT_A, add/use corresponding BIN_R, BIN_W, BIN_A definitions. Correction to
OpenHiddenFile(), which would have appended text to a binary file -TD
* combined lynx_html_item_type and lynx_printer_item_type structs as
lynx_list_item_type to simplify LYReadCFG.c and incidentally fixing a bug in
add_printer_to_list by merging it with add_item_to_list -TD
* implement a simple workaround for staircased messages from running xli as an
external viewer, with lynx_nl2crlf() function -TD
* add bright-blue.lss sample (from IZ) -TD
* modify makefile.in's to use symbol _O for object suffix to allow simple
override for OS/2 EMX -Zomf compiler option (request by IZ) -TD
* add HAVE_LYHELP_H definition in config.hin and use that in LYGlobalDefs.h
to workaround misuse of HAVE_CONFIG_H in makelynx.bat -TD
* work-around in LYrefresh() when curses pads are used, for special case where
cursor is not set properly when prompting with long subject line for mailto
URL -TD
* eliminate some pointer mismatch compiler warnings in LYEditInsert() for
EXP_KEYBOARD_LAYOUT configuration -TD
* improve handling of tables with respect to bad HTML. Also took an
opportunity to macroize a couple of places which missed in
unobfuscation-of-faking <td></td> (this faking happens when line break
happens in a non-first column of a table) -IZ
For example:
<TR>
<TD>
<FORM ACTION="FrameWork.class" METHOD="post">
y
</TD>
<TD>
<DIV>
x
</DIV></FORM>
</TD>
</TR>
Note FORM which spans cells. -trace'ing it gives very unintuitive
results: it skips </TD> inside FORM, but not <TD>. Then it supplied
</TD> when the FORM ends.
* repair treatment of colspans in TRST, making it work again in one of the
special cases it worked before. Another bug was in interaction of
justification and tables -IZ
* marked more TRACEs in TRST as "BUG"s -IZ
* TRST would sometimes produce non-intuitive results if <td> follows </tr>.
Add error recovery for this case -IZ
* corrections for nested-table configuration -IZ
+ make trailing <BR> in table cells "behave well" again (the following cell
would not be horizontally offset).
+ fix highlighting of multiline links inside tables, and a "80M tracelog" bug
(due to a misprint update of the enclosing table was performed once-per-row
instead of once-per-table). Extra updates would not hurt, but led to
slowdowns and quadratic-size logs.
+ fix a special case with table-in-table for partial-display
* resizing a window on a console may lead to a switch of the character-cell
size. The "downloaded font" loaded during an auto-switch of display-charset
may be no longer valid. In this case, force a re-download of the suitable
font for the current charcell size -IZ
* add reverse-video style for forwbackw.arrow to lynx.lss -TD
* while an error in .lynx-keymaps is fatal, but a more or less equivalent error
in the KEYMAP section of lynx.cfg is benign. Make them both benign -IZ
* change remaining uses of lookup_keymap(LYK_xxx) to LAC_TO_LKC0(LYK_xxx) -TD
* modify set_clicked_link() to return lynx keycodes rather than character
values -IZ
* remove line_for_char() function since it is used for HTLine.start
computations -TD
* several changes to GridText.c -IZ
+ '#' (shown at the UL corner when there is a toolbar) is shown even at the
beginning-of-the document.
+ with mouse enabled, the first 6 chars in the UL corner were "always"
sensitive to Click-1, behaving as PREV_DOC (usually on Left). This patch
changes this logic (for color-style):
If '#' is shown there, clicking on it behaves as pressing #;
Clicking on the next 6 chars behaves as PREV_DOC/NEXT_DOC (3+3);
+ if you define a style for forwbackw.arrow, then suitable arrows are shown
in these 3+3 positions; in fact they are shown only if it makes sense to do
PREV_DOC/NEXT_DOC, providing additional feedback.
+ remove the first empty line shown on any HTML document.
+ correct an off-by-one error in the removal-of-zero-length-markup logic.
Due to this bug, zero-length markup was never removed, which led to
accumulation of style change entries, eventually to a buffer overflow. At
this moment lynx color-style engine would give up, resulting in
incomprehensible ocean of colors on the display. To demonstrate, make a
select entry with more than 46 entries. [My auto-display-charset logic
added 2 new encodings to the table of Lynx, bringing the number to 46 on
the 'o'ption form. ;-]
+ fixes a bug with incorrectly calculated width of a numeric tag [12]
as far as 12 is 10 or more (still fixes Debian #68542).
+ remove unused members from HTLine struct.
+ make variables underline_on and bold_on private.
+ rewrote insert_blanks_in_line(), splitting out move_anchors_in_region().
+ make split_line() easier to maintain by adding variables to represent
common subexpressions, e.g., s_post, s_pre.
+ use set_style_by_embedded_chars() in split_line() to simplify/improve test
for whether lynx should add a bold/underline control.
+ recode to eliminate HTLine.start
+ recode to eliminate HTLine.chars
+ several changes to split_line(), using pointers to HTChangeStyle structs
rather than array indices.
* adjust some ifdef's to make configure --disable-trace compile -TD
* correct allocation size in mailcap_substitute(), which did not count the
trailing null -TD
* add configure --enable-vertrace option, to put __FILE__ and __LINE__ into
trace log -PG
* improve description of USE_MOUSE in lynx.cfg -PW
* eliminate a few references to USE_HASH and LINKEDSTYLES in documentation -TD
* fix a comparison in HTChunkPutUtf8Char() to work with EBCDIC -PG
* fix a typo in LYCharUtils.c CTRACE macro, amend tracing to avoid suppressing
a related user message -PG
