Change History of libwww
This is a list of changes to the W3C Reference
Library in reverse chronological order.
Library 3.1, November 14 1995
Official release
Library 3.1pre3 Release Notes, November 13
This is a last test of the 3.1 release. The official 3.1 release will
follow in a few days. The purpose of this third pre-release is simply
to avoid any obvious problems while we still have time. Very little
will change in the final release! The big difference is that Windows
NT is fully supported!
New Features and Interfaces
- Changed "rs6000" to "AIX" and "decstation" to "ultrix" in
BUILD script. The previous names were not obvious
- Have created HTProt
module which handles protocol module registration. It used to be
in HTAccess module, but
this module is now uniquely for user requests
- Changed the names of the following functions in the HTProt module
HTRegisterProtocol -> HTProtocol_add
HTProtocolDispose -> HTProtocol_deleteAll
HTProtocolBlocking -> HTProtocol_isBlocking
- Canonicalization now understands host names terminated with a ":",
for example "www.w3.org:" is converted into "www.w3.org"
- HTEvnttd.c is removed from the source tree; it's no longer needed.
Likewise, HTEvent.c is no longer needed; it has been superseded by
HTEvntrg.c and HTEvntrg.html.
- Added support for REENTRANT versions of
getlogin_r
gethostbyname_r
gethostbyaddr_r
ctime_r
localtime_r
gmtime_r
asctime_r
ctermid_r
rand_r
readdir_r
except in HTFTP
module as it will be changed later. Some of the function cause
problems on Solaris...
Bug Fixes
- Fixed bug in HTBind_getSuffix that caused garbage file suffixes
- Fixed memory leak in HTAnchor if a child has more than one destination
Library 3.1 Prerelease 2, November 1 1995
The code word for the 3.1 release is support for remote collaborate
work where people can use HTTP and the Web as a remote authoring
environment. The reason for the slight delay is that this release has
a new "Post Web" model for implementing PUT and POST, the
documentation has been reorganized and rewritten, and some other
important features have been incorporated. The Post Web model is
described in the new documentation, see the reference below.
In addition to the new set of features and functionality this release
also is the first example of source code distributed under the W3C
conditions. This means that the code is available to consortium
members only within a month from the release date.
A lot of the work put into this release has been to update the API of
the Library. This is mainly described in the new "User Guide", so
please do read this and remember that comments are welcome!
New Features and Interfaces
- The Post Web model is supported by the following methods to handle
the HTRequest object
- HTRequest_removeDestination()
- HTRequest_linkDestination()
- HTRequest_unlinkDestination()
- HTRequest_removePostWeb()
- HTRequest_killPostWeb()
- HTFile module is
completely rewritten as a state machine much like the HTTP module. It is now
possible to have non-blocking, interruptible I/O and to PUT and POTS
from a local file as well as from a remote HTTP server.
- HTCopyAnchor is rewritten to use the PostWeb
- The thread model is extended to include a HTThread_kill() function
so that threads are terminated immediately upon request
- HTProxy module is
introduced. This module substitutes the environment variables for
defining gateways and proxies. It can now be done dynamically at run
time. For backwards compatibility HTProxy_getEnvVar() can be used to
read the most used environment variables.
- Taken socket read/write functionality out of HTFormat and created
HTSocket module which
handles all the basic network access
- Spawned HTMethod
module from HTAccess module
- Better handling of WAIS src files and use of gateway information
- Upgraded the WAIS to handle version 0.5 of the freeWAIS library.
- Better handling of media types from WAIS responses (guessing)
- All HTTP headers can now be transmitted and received and they can
all be enabled/disabled using a bitmask.
- New functions to support accept encoding, language, and charset
- Guess stream now handles macbinhex format
- No more circular references in any of the Library include files
- Introduced REMOVE and RMDIR as macros instead of direct system calls
- Removed HTRequest_clear() - it's not safe to reuse a request object
- HTStrip() is now placed in the HTString module
- introducing the method used in the link object in the anchor
- HTTP modified to support PostWeb
Bug Fixes
- Cache is now avoided if in secure mode (no access to local file system)
- Bug fix to allow simultaneous read and write on the same socket
- Stream stack now dumps to local file if no conversion can be made
- Bug fix that caused core dumps for HTTP 0.9 servers
- Bug fixed in stream stack if system() call is not present. This
release has a new model called "Post Web" for handling put and post
from a source to a multiple number of destinations. Furthermore
Library 3.1 Prerelease 1, May 20 1995
A lot of the work put into this release has been to update the API of
the Library. This is mainly described in the new User Guide, so please do read this and remember
that comments are welcome!
New Features and Interfaces
- Windows NT Support (and possibly Windows 3.1 with Win32S) thanks
to Charlie Brooks, <cbrooks@osf.org>
- A lot easier handling of headers in the HTTP module including
support for extra headers
- Improved HTTP/MIME
parser which recognizes 99% of the HTTP headers The rest will be
ready in the next release! This includes support for "charset" and
"level" parameter
- Support for PUT and POST. This is not yet fully implemented but it
is possible to experiment with it
- Big enhancement of the anchor module with support for all HTTP/1.0
headers, garbage collection etc.
- The Cache manager is made more object oriented with a broader set
of methods. The garbage collector is not the best
- HTBind module created for better bindings to file system with new
hash function for improved speed and more functionality than before
- Created HTDateTimeStr() and HTMessageID() in HTString
- Separated HTStructured into its own stream definition module (HTStruct.h)
- Introduced STREAM_TRACE and BIND_TRACE as new debug flag
- Original reason messages are now passed back as a parameter by the
error handler when talking to a remote HTTP server
- Introduction of error_format in the request object. This can be
used to get debug information out of the Library
- Better handling of media types in FTP and Gopher including
recognition of UU encoded files
Bug Fixes
- Eventloop responds now faster on events as it more often does a select
- HTTP version strings are now string and not floats
- Many platform dependent macros introduced and a lot of cleanup
CERN
terminated its direct engagement in the World-Wide Web with the
release of Library version 3.0. The code is now developed and
maintained at W3C.
Library 3.0, Mar 21 1995
Many of the modifications and new features are mentioned under the
pre-releases.
- Changed all float to double in order get it
consistent with the working floating type in C
- Fixed problems with memory in HTML.c
- Introduced definition of
errno
constants for WIN32,
as WinSock doesn't define them using BSD notation
Library 3.0 Prerelease 3, Mar 10 1995
New or Changed Features
- All library include files which contains public information for
applications are now contained in the single include file WWWLib.h which is the only
one necessary PLEASE DON'T USE ANYTHING ELSE!!!
- Changed TRACE messages so that the target is the macro TDEST and
not stderr. This means that on platforms that don't support stderr,
TRACE messages can be redirected to a local file.
- Due to the PC Port some modules (definition and declaration files)
have changed names so that the max length is 8 characters:
- Move EnableFrom to HTAccess module. This
variable determines whether the HTTP header From: should be
generated. The default value is off
- Sockets are no longer assumed to be small, non-negative integers,
but uses macros. This should ensure portability to Windows NT.
- Introduced socerrno and errno so that WinSock can use its own
definition whereas `local' errno can still use the well-known version.
- Introduced
error_stream
as field a HTRequest
object. All information contained in HTTP responses which don't
naturally contain a body entity, for example redirection codes (3xx)
and client error codes (4xx) will be put down this stream so that it
can be put into a debug window.
- HTNewsHost is now a local variable in the HTNews module. Use
HTGetNewsHost and HTSetNewsHost to set and get the current value. The
news module will be rewritten in the near future as it has many
problems.
- The HTTP module
understands all HTTP/1.0 return codes and is more solid
- Many portability problems has been solved and optimized. Most
system dependent things are now put into tcp module
- Interface to CSO name server made nicer - generates correct HTML
Bug Fixes
- file:// no more tries ftp:// if host=localhost
- Improved proxy support and fixed bug when reloading a document from a proxy
- Bug fixed in HTGetHostName() which didn't include a dot <.>
- Bug fixed if UserID/passwd was not correct and don't want to retry
- HTErrorAdd and HTErrorSysAdd no always return HT_ERROR
- Fixed bug in HTGetDomainName when no domain name is present at all
- Add output_flush to request object
- Uses IOCTL as a macro now - not fcntl
- and a lot of other stuff...
Library 3.0 Prerelease 2, Dec 2 1994
- Introduced memory cleanups from Eric Sink into
HTLibTerminate()
- Now the client can provocate a call to
HTEventRequestTerminate()
even when the request never
enters the eventloop. This is necesary so that the client can cancel
busy icons, spinning globes etc.
- Introduced
EVENT_TERM
as return code for the
HTEventHandler function
HTEventHandler() now
has a double pointer so that the
request pointer can be modified from the client
- Fixed bug in
HTSearch()
and
HTLoadRelative()
where wrong return code was returned
(BOOL instead of int)
- Introduced BlockingIO field in the request object to override
the the mode registered in the protocol object. This can be used as
an easy way to make blocking I/O
Library 3.0 Prerelease 1, Nov 26 1994
New and Changed Features
- Introduced the function HTLibInit() and HTLibTerminate() which
MUST be called when the application starts up and terminates.
- Introduced the modules HTThread and HTEvent. HTEvent is the client
interface when using multithreaded functionality and HTThread is the
internal socket management
- All __STDC__ defines now concentrated to HTUtils.html where it is
called _STANDARD_CODE_ so that _cplusplus also handles this
- `new' and `template' not used a names anymore (confuses C++)
- Removed from field in HTRequest object. This is now handled by
the functions HTGetMailAddres and HTSetMailAddress and the flag
HTEnableFrom in the HTTP module.
- Changed HTSetMailAddress so that a call with parameter equals NULL
or "" clears the contents of the mail-address.
- The number of parameters to Streamstack function is now compatible
with the arguments to a stream converter, so that we don't loose any
information while putting up the stream stack.
- HTOutputSource variable is removed. You should use WWW_SOURCE in
the request object
- HTGuess stream is a a converter compatible stream so that it
actually can be setup as a converter
- The stream methods `abort' and `_free' now returns int instead of
void. On success from these methods `_free' returns 0 and `abort'
return EOF
- Taken HTEscape and HTUnescape and put them into the HTEscape
module. The functionality is the same but now they can be used in
utility programs without linking in the whole Library
Bug Fixes
- Removed bug in WAIS module which caused a lot of core dumps
- Removed bug in format classification from URL suffix in HTGoper
when the file was plaintext
- localhost is now recognized again after canonicalization
in
HTLoadFile()
- WAIS SEARCH now produces proper HTML
- Max number of lines in WAIS decreased to 200 as 250 (previous)
dumps core
- Bug fixed in
HTGetHostName()
if we must use the
getdomainname() function.
- Added some support for SCO
- Handling of gopher items of type ERROR (3) changed so no more core
dumps in server
2.17 Release on November 25 1994
New and Changed Features
Bug Fixes
- Fixed memory leak in HTWAIS Doc retrieval. However, the
functionality or performance has not changes
- If no host is found in the URL then no attempt is made to connect
to host 0.0.0.0 that is localhost. Some hosts do have an alias for
this address
- Fixed free memory read in redirections. Put redirection counter
into request object. Now no more than (default) 10 redirections are
allowed
- Fixed bug in FTP module to handle really slow hosts in the select
call. The select timed out without the right action taken.
- FTP module chopped off the first line of a Windows NT ftp server as
it doesn't send a traditional first UNIX line. Fixed! Well, it
did look like UNIX, but no more than that :-(
- Problem in HTTeXGen. Some markups was spread over a new line, and
LaTeX doesn't like that.
- Remove the
ACCESS_AUTH
define as it is never used
anymore (no more compilation without access authentication)
- Fixed bug in the ISO Latin 1 translation table in HTML.c. This was
a problem for estonian documents or other with many special characters
- Fixed bug in HTSimplify not skipping host names. HTSimplify is
made faster and is now only called once (both from the server and the
client). Before it was called 2-3 times.
- Bug found in FTP URLs containing UserID and Passwd fixed
- Bug fixed in name generation in client cache
- Removed bug in FTP and IP-rotation on multi-homed hosts. When FTP
server is in PASV mode it sends back a port number on a specific host.
In this case we can't use IP-address rotation.
- Bug with FTP IP-address network order fixed for PASV mode
- Gopher errors (code 3) are now just put as a string as they are
not real error
- Bug fixed in HTWriter.c function
flush()
where a
partial success in NETWRITE would produce a wrong output (repeated
buffer)
2.16 Prerelease 2, November 1994
WAIS Client
The WAIS client has been improved and some bugs have been fixed:
- Bug in the parser of the search result from the WAIS module fixed
- Maximum number of lines presented from a search made a configuration
variable. Default value is 100 (was 40)
- Introduced WAIS's own error messages as they are returned from the WAIS
library
- The presentation of WAIS on the screen made nicer (well - I think it
is!)
HTTCP Module
- Bug in the host cache fixed
Access Authorisation
- Premature free of memory fixed
- Missing initialization fixed
2.16 Prerelease 1, April 1994
New Features and Changed Interfaces
HTTP Client
HTTP module contains the code
for the HTTP client. The module is now reorganized and made more modular.
- Automatic Redirection
- Now supported by the HTTP Module. The name of the new URL is parsed
to the client via the error_stack as a ERR_INFO message, see
HTError module. The maximum
number of redirections is set by the variable HTMaxRedirections.
- Referer Field in HTTP request
- Clients are provided the possibility of
sending a Referer Field in a HTTP Request. This is done by
filling out the HTRequest->parentAnchor field.
- From field in HTTP Request
- Clients can now send the full email address of the current user in the
HTTP From field. The feature is turned off by default as it might
get a bit tricky through a Proxy.
- 204 Response
- Support of return code `204 No Response'
FTP Client
HTFTP module contains the code for
the FTP client. The FTP client has changed a lot in this release. It is now a
complete state machine where the actual action executed is a function of the
current state.
Gopher Client
The Gopher has been revised and
improved error handling has been implemented.
- Information Messages
- Some Gopher servers send back information messages in a line containing
"error.host". This information is treated like login information from FTP
servers so that it is represented as a message before or after the actual
listing.
- Iconized Listings
- Listings now contain icons in the same way as the other listings.
- CSO Name Server
- The CSO Name Server client outputs in HTML and not only <PRE> as
before.
- Content Type Recognition
- The Gopher module uses it's own content-type recognition inherited from
HTTP when handling gopher text and gopher binary files. This means, that
e.g. PostScript files get handled correctly.
Local File Access
The new version of HTFile module is a lot smaller as all Directory listing
stuff has moved to HTDirBrw module. New error handling has been implemented.
Passive and Active Connection Establishment
Calls to connect() and accept() now go through the functions HTDoConnect()
and HTDoAccept() respectively.
Cache of Host Names and Addresses
HTInetParse() that is called from within HTDoConnect now has an internal cache
of the names and (possible multiple) IP-addresses of visited hosts. This
minimizes the access to the file /etc/hosts and the Domain Name Server, even
though aliases are not recognized in the cache.
The default cache size is 500 entries and a host stays as long as a connect()
succeeds. That is, if connection is refused for some reason, the host is taken
out of the cache.
The time to make a connection to a multihomed host is measured every time and
a mean access time is calculated so that HTDoConnect always takes the fastest
IP-address, see Future plans.
Improved Functionality of DNS requests
The Library now provides functionality for obtaining the full mail address
of the user, full domain name of the host and also the possibility for
setting both values. This means that the user can use his official email
address, e.g. in the HTTP request.
Long directory listings for HTTP, FTP and files on the local file
system supported. For the moment only a part of
the functionality, e.g, sorting, which columns to show etc. is exploited, see Future Plans.
Icon Management
Icons in directory listings are bound to MIME content-types and encoding. They
can be found in the HTIcons
module. The default set of icons is set up using HTStdIconInit() and new
icons can be added dynamicly using HTAddIcon().
File Descriptions in Directory Listings
File descriptions are supported for long HTTP directory listings. The default
thing is to peek the title of the HTML files.
Error and Information Message Management
A new error handling module is introduced in HTError. It uses the error_stack entry in the
HTRequest object. It
handles nested error messages so that we can give a reason for the error, e.g.
Error in ...
This error occurred because ...
This is caused by ...
etc.
It also makes it possible for the Library to pass information back to the
client so that the the Library doesn't act like a `black hole'. An example is
HTTP redirection with status code `Moved 301'. Now the new URL is parsed back
to the client via the error_stack so that the client can update the reference
when possible.
The function that generates and outputs the error messages to the user
is put into HTErrorMsg Module so that it can be overwritten by a smart
client or server.
Guessing the Content Type of a Stream
The HTGuess module reads a part a stream and determines the content type with
the highest probability from a statistical analysis.
Minor Stuff
- tmpnam()
- Because of problems on NeXT platforms the tmpnam() function is now
replaced by HTFWriter_filename() in HTFWriter.c. The function has two
modes: Give back a hash name or the last part of the URL (which
normally is more readable).
- HTMLPutImg()
- New function to make it easier to put out an HTML <IMG> tag.
- HTParseInet()
- Added one more parameter to tell whether it is a multihomed host or not.
(This is used in the host cache).
- HTInetStatus()
- Should no more be used directly but is called from HTErrorAdd so that the
message goes all the way back to the user
- HTError
- This typedef is now obsolete and will be removed in future releases
- HTLoad()
- Added new parameter to HTLoad: BOOL keep_error_stack. If YES then the
error_stack is not cleared. This is used in redirection etc.
- HTLoadError()
- Because of the new HTError
module, this function in HTML.c is not needed anymore.
Bug Fixes
This is a list of fixed bugs from earlier versions.
- Memory faults in HTSimplify() in HTParse.c has been fixed
- README files in directory listings now know how to handle '<', '>'
and '&' correctly. Though the file still has to be Ascii. See
future plans for handling this file.
- tmpnam is no more used in the Library because of problems on NeXT
platform. Instead a new function called HTFWriter_filename() in
HTFWriter.c is written.
- HTInputSocket_getCharacter now returns a int and not a char so that EOF
is no longer a member of the char set.
- HTMLGen_start_element() is only allowed to put extra '\n' in <PRE>
mode if it is between parameters in a tag
- Changed type of <IMG> into SGML_EMPTY so that it doesn't expect
end tag <\IMG>
- Nested <PRE> is no more a problem in HTMLGen_start_element.
- Removed all #elif as not all compilers on HPUX likes it.
- Changed HTChunk such that chunk->data is '\0' terminated at any time.
This actually makes HTChunkTerminate less needed but be aware that
HTChunk->size changes.
- Removed non-portable d_namlen field in HTMulti.
- Moved definition of NO_GROUPS to tch.html
- Moved definition of HT_MAX_PATH to tch.html
- Proxy server now closes connection in HTTP.c. This was only problem in
non-forking servers (VMS).
- Definition of HT_NO_DATA moved to HTUtils.html where the other
return codes are placed.
- Functions from HTAlert Module that prompt the user don't get
confused about ctrl-D anymore.
27 March 94 2.16beta VMS version
25 March 94 - 2.15
General Upgrade
International
Bug Fixes
- Bug fixed in HTFile.c prevented .multi multiformat links from
working under Solaris, maybe other SYSV.
- Bug fix in client HTTP: "Accept" line params preceded by ";" now
as per spec.
- Bug fixed in HTBTree.c that crashed for some large directories.
15 December 2.14vms
17 November 2.14
- Contains port to VMS.
- Bug fix in HTML generation -- line wrapping code produced garbage.
Affected servers working as gateways and also editors writing back
HTML.
- Buf fix: static string returned by crypt() was free() 'd.
4 Nov 93 Version 2.13
- Bug fix: FTP text transfer don't end when 8 bit characters used.
Still end on character -1. Thanks to Bjoern Stabell
(bjoerns@staff.cs.uit.no)
- A single function HTPromptUsernameAndPassword() so that GUIs can
have a single authentication dialog box.
- Extensive filename suffix recognition defaults.
11 Oct 93 Version 2.12
- Authroization in. See Ari's documentation. Everything is
back-compatible, but there are large extenions to the rule file
syntax, plus new ACL and protection setup files. Authorization is
done by password in the clear now, with hooks for public key later.
- Some other bug fixes. Not all the reported ones.
8 Sept 93 Version 2.11
- Binary transfer problems tackled in HTTP. Yukky problem of
existing illegal 0.9 server producing binary which looks like text is
unsolved. No problems with HTTP 1.0 transfer.
- Streams: end_document method removed. "Abort" method added as
requested at W5 -- use this when a pipe (stream stack) is broken by an
error prevents execution etc of partially written files for example.
- New stream HTNetToText for converting Net ASCII to local C
representation.
- Bug fix: Directories represented with anchors all with empty
string (as opposed to no) names: many NAME="" in anchors.
- Bug fix: application/octet-stream replaces application/binary as
per MIME.
- CSO Nameserver code to HTGopher added as Mosaic originally from
???. (AS)
- Bug fix: HTTPD would return an old-style (non-MIME) response when
sending back a file in unrecognised format, evn if client was using
HTTP 1.0.
Version 2.10 Not released due to WWWWW
- Bug fix: crashed with error message when doing a Gopher search.
- WAIS type "HTML" recognised as HTML. Other types treated as
application/binary.
30 November 1993, version 2.09a
- Bug fix: A space was not allowed befoe the tagcloser (>) of an end
tag. Now it is. Also (untested), empty close tags should be allowed a
la "<h1>heading</>". Not recommended, but in.
- Bug fix: HTML nesting stack overflow check.
- Bug fix: Compilation under IBM MVS didn't work.
23 November 1993, version 2.09
At last this stupid library is aware of content-transfer-encoding.
When defining file suffixes you must define not only the content-type
(eg application/postscript) but also the encoding (eg binary, or
7bit). The first effect of this is to get the proper mode selected
for FTP transfers. This means you can do a
www -source ftp:/xx.yy.edu/pub/junk/foo.tar.Z > junk.tar.Z
and it will work as expected.
On the client side, you can define the presentation method for any
given MIME-style 'content type". This is done in the rule file too.
2.08
- You can define file suffix conventions in the server and/or client
rule files. This allows you to set up a server which for example,
trateas .ai files as application/postscript, etc, or specifies that
.ME is generally text.
- You can define how a new content type will be rendered in the rule
file of a client.
15 November 93, version 2.07
- If you telnet to the www client (-h option): 1. it is more secure:
No local file access. 2. you can use /etc/www-remote.url file to
specify the url of the home page for telnet users.
- Library uses fopen() rather than open(), allowing file access on
non-unix machines.
7 November 93, 2.06
- Check against local hostname in file access is now string
insensitive.
- HTML parser: entities were not expanded at outer level.
- HTTP client sends client name and version. Requires HTAppName
- FTP client fix: Continuation lines which do not have - in are now
handled properly as per the spec.
May 1993 version 2.05a
- Bug fix in directory reading of local files -- it didn't work!
The stopped the daemon working on directories.
- Bug fix in DIR handling for browers: tabs work again in directory
listsings.
22 April 1993 version 2.04
- WAIS handling code in library, no need to go through a gateway of
you compile with the right options abd link with freeWAIS. First
version of this, no bells or whistles.
- tcp.h systems specifics for SCO picked up from mosaic but
directory handling not fixed yet ...
20 April 1993 version 2.03c:
- Use of identifier "this" removed to prevent conflicts with C++
- _AIX cpp defined picked up for AIX.
- In networking code, no assumption that \n is 10 on even on ASCII
machines (for Mac/MPW).
- Server bug fix after Sebastian.Wilhelmi@isst.fhg.de -- exited with
bad status even if all OK.
19 April 1993 version 2.03b
- Distribution bug fix: s/Specific/All/ on line 2 of
WWW/All/Makefile.product
- SGML bug fix: treatment of entities was on when would be off and
vice-cversa.
- Sun binaries linked with -Bstatic to make them transportable
- Bug fix: Sometimes, client would ignore first part of returned
file.
17 Mar 93 Version 2.02-beta
- Bug fix: Falls back to old HTTP with servers which don't like the
new HTTP.
- BUILD file for easy installation of library, httpd and www
15 Mar 93 Version 2.0 alpha:
Incompatible library release has cleaned up interfaces. Developers
read the .h files! Version 2 libraries must be compiled with version
2 products and vice-versa. Version 2 clients will access (most)
version 1 servers OK, version 2 servers will respond correctly to
(all) version 1 clients.
- Bug fix: Gopher connections wasted socket numbers and eventually
used them all up. (Thanks Marc Andreessen)
- Rule file used by clients as well as servers.
- MIME parser takes content-type field from MIME messages and
invokes appropriate registerd presentation method for each type.
- Local and remote multiformat files.
- ***HTSearch and HTLoadRelative parameters changed! HTMainAnchor
and HTMainText globals are no longer used by the library.
- HTAccess package now registers known protocols in list.
- HT{G,S}etNewsHost available from HTNews module.
- SGML parser speeded up
- New software intrerface introduced: HTStructuredClass. This
should make use of the library easier with clients, and allow more
code in common between clients and servers.
- Hooks for handling new formats with other applications
- General hooks for status messages, user query, progress
monitoring, etc. (HTAlert module)
6 January 1993, Version1.1a
- Can revisit telnet nodes.
- Tn3270 access type accepted.
- FTP password for anonymous is now WWWuser@ withouyt a hostname,
for software on ftp.uu.net etc.
- Bug fix in HTML.c: Would crash when a list was the first visible
element in a text object.
- Added <PRE> tag as in new HTML
spec.
- Added numeric character reference handling for future use.
December 1992, Version 1.0c
- Fixed bug in FTP handling (FTP file retrieve put control
connection in bad state)
- Fixed bug in Gopher handling on non-ASCII platforms. Also, bug fix
in Gopher search of index whose name contained characters (like
blanks) escapes with %.
- Fixed bug in NEWS handling, failed on non-ASCII platforms.
November 1992 Version1.0b
- Fix some bugs in Make system.
- Memory bug fixed: On failure to connect to HTTP server, it would
free() an uninitialized pointer!
- Some trace messages were output to stdout instead of stderr
- Allow "ftp:" prefix on URL . Effect is currently equivalent to
that of the "file:" prefix.
- Local file access not allowed in secure mode. (telnet access was
never allowed in this mode). Secure mode is used for telnet server
and mail robot.
November 1992 version 1.0
- Library libwww.a made independently of browsers to save time and
space and to force good modularity
libwww@w3.org, December 1995
