Following the normal W3C conventions, there were two different
kind of releases of Jigsaw. Member release are provided
to W3C members, a month in advance of the Public
Release. Depending on their status the member release may get a
different release number then the public release. On this page,
you will find the release notes for the different versions of
Jigsaw (which don't necessarily coincide with member
release). From the beginning of 1998, the releases are only
public ones, we still add the word "public" to avoid any
confusion.
NOTE! The odd number in the
middle state that this is NOT a stable release, not that it is unstable,
but it means that not all the features are present, and that some more
testing is needed until it gets its even middle number.
Jigsaw 2.2.6
A public release, made on April 10th, 2007.
This version is a bugfix and optimized version of 2.2.5. It may be
the latest using jdk1.2 only code.
New Features
Support for more XML Parsers in the Resources deserialization code
- Added support for connection reuse policies in the
Client stack.
- Added a default policy to reuse the same connection when the
thread matches (in HttpBasicConnection)
- Added a socket timeout on request
parsing, to avoid having it linked to request timeout
- The Servlet runner thread now use the server
timeout mechanism to interrupt the running thread when the server
is closing the request on timeout.
- Added a method to print Dates in ISO 8601 format without
milliseconds
- Added a "detach" method to HttpBasicConnection to remove a
connection from the list of used client connections but without
closing the socket immediately (used when the client hits a
HTTP/1.0 server that doesn't send Content-Length).
Bug Fixes

- Fixed bug in DateParser (wrong timezone offset) thanks to Menno Jonkers
- Optimized a bit Digest Auth (the RFC2069 one) and implemented Digest Auth with qop="auth" per RFC2617 (available with SecurityLevel set to 2), See DigestQopAuthPrincipal
- Fixed a few WebDAV properties that were using wrong formats
- HeaderFilter now sets the relevant headers even when the reply is sent via the exception mechanism.
- More SSL and servlet related patches from Thomas Kopp.
- ActiveStream patch, under some condition, the same data
could be re-read a data chunk (thanks to Doug Borland)
- The servlet parameter decoding now uses the right charset.
- Fixed error when file timestamp was not modified but the file was actually modified.
- Fixed deadlock during store change notification when the sweeper is running (very rare)
- Fixed server client count when load is raising from LIGHT to DEAD
- Fixed Segment information unpickle, as the segment start and size were not properly parsed, leading to an infinite loop
- More SSL patches from Thomas Kopp, see changelog for more details.
- Fixed connection count when MimeParser did not started and connection was new.
- Client stack now reuses the
connection timeout parameter.
Jigsaw 2.2.5
A public release, made on June 8th, 2005.

It contains an updated version of the SSL code (that may require
the use of jdk1.4).
New Features
New Digest Authentication code has been added.
It now conforms to
RFC2617.
The old code was implementing only the
RFC2069
version of the Digest Authentication.
WebDAV support has been improved, interoperating with most WebDAV
clients now.

Jigsaw 2.2.4
A public release, made on February 18th, 2004.
This version is a bugfix and optimized version of 2.2.3.
It contains an updated version of the SSL code (that may require
the use of jdk1.4). It contains a security fix, so
you are encouraged to update as soon as possible.
New Features
The HTTP Client stack has been completely reworked to be
faster and to avoid keeping information on too many remote servers.
The client stack now also has a timeout on connect.
Bug Fixes

(ie it uses the
whole scale instead of the object serial mask), as it was leading to
infinite loops on huge sites.
Jigsaw 2.2.3
A public release, made on November 27th, 2003.

(need to figure out why it was called
twice though)

properties in a PROPFIND, with the
right statuds for the undefined ones.
- Modified AclFilter to take benefit of skipBody
- Added skipBody in Request, it allows a filter to skip an eventual
body in a better way than error
recovery.

resulting in locks done in the wrong order
in concurrent access

potential char to byte convertion problem has been removed. Also,
the closing of the stream has been fixed.

Jigsaw 2.1.0
A public release, made on September the 9th, 1999.
This release is the first release using the new serialization scheme.
It allows you to change the way the serialization is done.
As an exemple, and to provide an easier access to the configuration.
New Features
- New serialization scheme, the current version uses XML, see
the JXML format for more
information on how to read the serialized files.
- New admin exchange format, using
JXML, it allows you to
create administration scripts.
- A new upgrader will convert automatically the old Jigsaw stores
to the new format, the old stores are kept in a backup directory.
Bug Fixes
- more HttpRange can now be created: "-500","500-", by using -1 as
the default value
- The request parser now skip the body if sent directly by the client
when an error occured.
- Servlet are destroyed only if all the connections are closed
- Lister in Jigedit now defines the ACTION in the FORM
- Servlet bug fixed in getResource(), thanks to James Clark.
Improvements
- Directory listing now ends the URI of the containers with a "/",
preventing an extra redirect
- Logger now has a property to define the logging directory
Limitations
- The jdbmResourceStore has not yet been ported, a consequence is
the lack of CacheFilter in the proxy, but it will be replaced soon
by a completely new cache.
Jigsaw 2.0.3
A public release, made on July the 27th, 1999.
This release is a bugfix version of the 2.0.2, while 2.1.0 will add
new feature and will completely change the way the resources are
serialized).
Meanwhile, there are new functionalities, like the new Acl api, which
replaces the old auth schemes.
New Features
- new Acl API, more flexible than the previous auth scheme.
- Redirecter Frame now handles PATH_INFO.
- Charset and language dialects negotiation.
- Added MimeTypeArray and other basic attributes arrays.
Bug Fixes
- Bad request handling is better, previously, HTTP/1.1 without a
Host: header or a full URI was just closing the connection.
- Servlet indexer can now index servlets with full package name
- Bad permission on a file now fires an exception, rather than
(possibly) hanging.
- MimeAttribute null balue is now handled in jigadm
- Cache is now sending the right size for null documents
- Servlet's getReader now takes care of the encoding.
- ServletRequest now merges URI parameters and body parameters.

events)
- Cache is no longer blocking for non-sized multipart documents.
- Fixed loop in proxy when the proxy was on port 80 (fixed also if
it is the default https port)
- Fixed timestamp problem when a file has been modified in the past
(clock skew is a pain)
- Fixed max-connection and notification of waiting threads during the
deletion of an old kept-alive connection
- Cached VaryResource are now checking ETag the right way, no more
304 replies when it was just a cache revalidation.
- Multiple cookies are now sent using multiple headers (ugly but
cookies ARE ugly).
- Fixed ResourceStoreManager initialization, when another root
resource was set, it may end up in resource duplication and
problems while attaching frames/filters, also it was causing
deletion loops. WARNING! You may have to redo your configuration if
you changed the root resource!
- Fixed servlet timeout unit
- SSI Frame and servlet interaction fixed (no more chunking in that
case)
- Logger and port can be changed while the server is running.
- The "No logger" warning is more explicit
Improvements
- Servlet timeout can be disabled
- Servlet cookie maxage can now be -1 (unlimited)
- Language negotiation has been redone, it now check dialects
also
- Content negotiation now takes the order into account
- Realms now have a real feeder (administration tool)

handling of clients when load goes up (it means also better
performances)
- MirrorFrame now tweaks also temporary redirects
- Md5 constructor now allows an encoding string.
A public release, made on March the 31th, 1999.
This release includes the first version of the new administration tool
(jigadmin, v2). Along with that, numerous improvement over the old
version, like servlet API 2.1 support.
New Features
- Digest Authentication
- Http Extension Framework (HttpExtFrame)
- New JigAdmin. This one should be more intuitive than the other, but
still, you probably need to understand the design to take best out of
it.
- JSDK2.1 (Servlet API) support.
- Per servlet timeout is possible
- JNI port of LibUnix, thanks to Roland Mainz
- New logger ExtendedCommonLogger, doing log rotation and using ECLF
format

IOException when an error occurs
- 201 Created now generates the right response
- FileAttribute is now sent as a String in the admin protocol to
avoid automatic conversion of jdk1.2
- When indexing a file with multiple extensions, frames attirbutes
are now aggregated. It requires the use of the new default
indexer provided in the distribution, as the Content-Type
for modifiers (like .fr) is now
set to *none*
- VirtualHost now remove automatically the ":80" added by some
robots.
- Extension matching process now does "perfect" match, then case
insensitive match if desired.
- CgiFrame has now PATH_TRANSLATED defined

- Users can add environment variable in the CgiFrame
configuration
- ETag generation is done in one place, so you can overload it.
- URLDecoder updated to use InputStream AND Readers
- ContentTypeIndexer can now use wildcards (well only *) in its mime
type definitions.
- ThreadCache behaviour near the limit is now the right one, also
there is a feature to wait for all the thread of the cache.
- PassDirectory can now act as a normal DirectoryResource is the
pass-target is not set
Jigsaw 2.0.1
A public release, made on January the 18th, 1999.
This release has been done to allow people to use the admin tool
despite a JDK1.2 bug. So the fixed bug list is quite short!

Jigsaw 2.0beta1
A public release, made on April the 8th, 1998.
This is the first complete release of the new Jigsaw, with the new internal design.
Bug Fixes
There was almost no bug fix in the new resource model of Jigsaw, but there
was some modification of the HTTP stack, mainly about the handling of the PUT
method.
New Features
All the resources of the 1.0beta2 has been ported to the new 2.0 version.
This includes:
The new documentation is also more complete.
Incompatible changes
To avoid the name length limit on the Mac, the resource files used by
JigAdmin are now stored in a zip, the old version of JigAdmin
will not work with this new version, you then need to upgrade both the server
and the client to do administration.
Jigsaw 2.0alpha1
A public release, made on January the 31th, 1998.
This 2.0 release is the first release of the new internal design of Jigsaw.
Bug Fixes
This version as all the bug fixes of the 1.0beta2 about protocol issues.
Other bug fixes have no meaning here as the internals of Jigsaw have been
reworked.
Incompatibles changes
- The name of the classes are now org.w3c... instead of
w3c...
- The resources are no longer linked with the protocol, protocole frames
are added to the raw resources
- The resources are limited, DirectoryResource, FileResource,
PassDirectory, FramedResource, ContainerResource and
ExternalContainer.
- The new frames are:
- The filters are no longer placed on the resource, but on the protocol
frame.
- The admin server has been reworked to support framed frames.
- Support for active Resources through listeners. (bean-like event
model).
- Modification of the JigAdmin configuration tool to support
protocol frames and framed frames.
- The root store of the distribution is no longer needed to start a new
server, it creates its own store if none are present.
- The ResourceStoreManager has been completely modified, so the old
configurations for the 1.0beta serie will no longer work. You will have to
reconfigure your server entirely!
- The form-based configuration is invalid now and has been removed. You
MUST use the administration server to configure Jigsaw
New Features
- True reindexing now exists (This is real reindexing rather than deleting
the resource).
- Jigsaw will create the root store if not present.
- Installation program that modifies the property files of the servers
according to your configuration.
- Partial draft of the new documentation, the next
release will have a completely new documentation.
Jigsaw 1.0beta2
A public release, made on January the 31th, 1998.
This is a bug fix release of the previous beta release. The purpose of the
"beta track" is to improve the stability of Jigsaw. For further developments,
see the 2.0 track.
Bug Fixes
- Fixed revalidation mechanism with a no-cache directive.
- The update of a cached resource in case of a revalidation is now
correct.
- The Max-Forwards header is now well handled.
- The PUT and POST methods are now working well on
HTTP/1.1 servers.
- Fixed a bug in the Via header of proxied resources.
- Fixed default adds of HTTP headers that were wrong.
- debug of the classloader for servlets
- Bug fix in the jdbm enumerator.
Enhancements
- The indexers can now create "ghost" resources to allow more fancy uses
of Jigsaw, like shadow icon directories.
- Added the TRACE method of HTTP/1.1
- Added the possibility of templates in the indexers
- the GrepPutFilter forbid a PUT of a document containing a specified
string. Very useful when you edit your website from one server and you
doesn'y want to allow links to this server.
- Added a DateThread, if you want to speed up Jigsaw a bit (~10% by
switching loggers).
Jigsaw 1.0beta1
A public release, made on September the 1st, 1997.
This is just a bug fix release of the latest member beta release.
Bug Fixes
- Fixed a bug in Content-Length in case of Chunked encoding.
- Added more feedback when a configuration error occurs while using
JigAdmin.
- Fixed bug in the CacheFilter
Enhancements
- Added a new Resource, DirectoryLister, acting like when you access to a
directory, useful to make a small index.
Jigsaw 1.0beta
A member specific release, made on August the 1st, 1997.
Bug Fixes
- FileResource now supports the HTTP/1.1 If-Range header, and a
slight bug was fixed in the emitted Content-Range header
- The HTTP client side cache filter has been fixed (jdbmResourceStore
enumration was buggy)
- The Caught Exception trace in errlog has been removed (The trace was
the bug - tm)
- Fixed a bug in ICP message parsing (will now correctly handle message of
length exceeding 255 bytes)
- If it manages a shared cache, the CacheFilter will no longer cache
documents retreive through a request that has an Authorization
header.
- Fixed a bug in HTTP Date parsing (one of the three date format wasn't
parsed properly)
- Fixed a bug in ContentLengthInputStream (wrong size after an error on a
read)
- Fixed a bug in ActiveStream which was the source of empty documents
feeded by the proxy.
Enhancements
- Added a property in the ICPFilter
to disable caching of documents retreived through ICP
- JSDK/1.0 FCS servlet API support
- Powerful JDBC access through server side include.
This new feature allow you to querty any JDBC compliant database and embed
the result within your HTML page. Check the SSIResource api.
- PICS & JDBC.
A new LabelBureau implementation is available. It relies on any JDBC
compliant database as the storage mechanism for PICS labels, which makes
it more scaleable than the previous filesystem based approach.
- Servlet support has been upgraded to 1.0FCS; Support for automatic
servlet reloading has also been implemented (Jigsaw will detect that the
servlet class files have changed and will reload them automatically).
New Features
- Added a companion server to do the remote configuration.
The protocol used to communicate with the Admin servlet hasn't been
specified yet, and will probably change in the next releases of Jigsaw.
The client part of the API (w3c.jigsaw.jigadm.RemoteResource)
is unlikely to change though.
- A new graphical tool is available to do the configuration of Jigsaw.
Currently, this allows you to do everything the form based editor could
do.
- Support for the SAP
protocol has been included, as the starting point for multicast
proxy-to-proxy support. SAP is the Session Announcement Protocol (an
Internet draft)
- The ProxyDirectory
resource now supports ftp tunneling (it won't do caching until someone
tells me how ftp results can be cached)
- Support for a light multicasted version of ICP now available in the
proxy, turn your hundreds of useless 5Mo caches into a usefull 50Mo
collaborative proxy: the net is the computer ! Check the MICPFilter
client side filter.
- Resource can now be extended through the use of ResourceFrame;
The notion of HTTP filters has proven usefull enough to be extended for
non HTTP resources. You can now attach frames to resources that
describe users for example (such as the w3c.jigsaw.auth.AuthUser).
Incompatible API changes
Incompatible Configuration Changes
- Filters pickling as attributes
Filters pickling has changed: filters are now just a special resource
attribute, and follow the general pickling format. They used to be
special, and that caused lots of troubles.
Don't redefine the pickle method !!
- Cache directory hierarchy
The cache directory hierarchy has been made multi-directory: cached
entries are stored in a tree of directories instead of within a single
directory (lessen the load on the file system by decreasing the acche
directory size)
Jigsaw 1.0alpha5
A public release made on February the 13th, 1997.
Incompatible changes
- The AttributeHolder
unpickle
and unpickleInstance
methods, now take a third boolean parameter, that indicates if the
resource is to be initialized after unpickling. Warning if you have
written an 1.0alpha3 resource that redefines this method, you should make
sure to define the new format for this method (since it's the one that
gets called by the unpickling engine)
- The HttpReplyMessage setLocation
method now takes an URL, to reflect the fact that HTTP/1.1 specification
requires an absolute URL here.
- The getURL method of HTTPResource
has now been splitted into two diferent methods:
- String getURLPath()
- Returns the path of the URL of the resource (as a String)
- URL getURL(request)
- Retuns the full URL of the resource. With virtual hosting support,
it may happen that a resource has differnt URLs according to the
incomming requests, that's one of the reason for that split.
- AttributeHolderAttribute
semantics has slightly changed: it is up to resources using that kind of
attribute to initialize the value (if any) of that attribute, by calling
their initialize
method with appropriate default values.
- Resources can now refuse unloading, through the new acceptUnload
method. This allows to lock a resource in memory, whatever happens.
This should be use only with great care.
- The ResourceStoreHolder
interface has changed in the following ways:
- notifyStoreUnload
- Has been renamed to acceptStoreUnload,
and returns a boolean that indicates wether the store holder is
willing to get rid of any of its references to the store. If any of
that store holders return false the store will not ne
unloaded.
- notifyStoreShutdown
and notifyStoreStabilize
- Semantics has been slightly changed: it is nolonger up to the
store holder to perform the job. The first method is the one in
which the holder should get rid of all its references to the store
(by nullifying them), and the second one is just a
notification.
- The ContainerResource
lookupStore
method now throws an InvalidResourceException
if the resource exists in its store but cannot be restored. In such a
case, the DirectoryResource
will emit an appropriate error message.
- The ServerHandler
interface initialize
and clone
methods now provide a pointer to the ServerHandlerManager
as a first parameter.
- The resource and resource store APIs have been moved outside of
Jigsaw. After a year of experimentation, this code has proven
usefull outside the scope of the server itself, that's why we decided to
move it to a newly created package w3c.tools.store. If you
have written some resources, the only change for you will be to import
that new package in your class files. The precise list of classes that has
moved is:
- Attribute.java
- AttributeHolder.java
- AttributeHolderAttribute.java
- AttributeRegistry.java
- BooleanAttribute.java
- ClassAttribute.java
- DateAttribute.java
- DoubleAttribute.java
- FileAttribute.java
- FilenameAttribute.java
- HolderInitException.java
- IllegalAttributeAccess.java
- IntegerArrayAttribute.java
- IntegerAttribute.java
- InvalidResourceAttribute.java
- LongAttribute.java
- ObjectAttribute.java
- PropertiesAttribute.java
- Resource.java
- ResourceLocker.java
- ResourceShadower.java
- ResourceStore.java
- ResourceStoreHolder.java
- ResourceStoreManager.java
- SimpleResourceStore.java
- StringArrayAttribute.java
- StringAttribute.java
- UnknownResourceException.java
- The ResourceStoreManager
unpickleProlog
method no longer returns a boolean. Instead it throws one of:
- NotAStoreException
- If the file preambule doesn't match the store cookie.
- InvalidStoreClassException
- If the class willing to load that repository doesn't match the
class that saved it.
- InvalidStoreVersionException
- If the repository version doesn't match the loading class
version.
Compatible changes
- HTTPResource defines a new verify
method, that might be called by a resource store salvager to check the
consistency of the resource.For example, file system based resources will
use that method to check that the file or directory they wrap still exist,
and delete themselves if not.
- DirectoryResource
listing now emits HTML3.2 compliant documents, along with a link to the
container (when possible)
- The realms catalog no longer uses absolute pathes, it will not however
upgrade all realms catalog to not using absolute path. Relative path are
relative to the server's auth directory (typically
config/auth)
- The w3c.jigsaw.space property is no longer settable through the
Admin properties editor. This was an oversight. The only way to set the
space for a server, is through the -space commandline
toggle (check the command line
page for more details)
New features
- A new SalvagerResource
has been written. This resource will walk through the entire resource
space, to check for:
- Cycles in resource stores (due to Jigsaw bugs)
- Unused resource stores (it garbage collects the stores)
- Synchronize resources with the file system, by calling the verify
method of all resources.
- A new ResourceWalker
interface is available, along with a WalkerEngine. These
two classes provide respectively an interface to handle the walk, and an
engine that will trigger call to implementors of previous interface
while walking through a resource space.
Bug fixes
Numerous bug fixes have been omitted from the list, that list only the main
ones:
- The ResourceStoreManager
had numerous bugs, most of them should now be fixed.
- The ICPFilter
HTTP client side filter that implements the Internet Cache Protocol should
now be compatible with Squid implementations
- CVS has been fixed in numerous ways; the PutList resource should now be
usable.
- The basic class AuthFilter now
performs authentication during lookup, rather then at
ingoingFilter's time.
Jigsaw 1.0alpha4
A member specific release, made on January the 13th, 1997.
Incompatible changes
- Properties are no longer saved in a single file, each ServerHandler has
to manage its own property file. The file is designated through the server
identifier. This means that older httpd.props file should
be changed by:
- Renaming them to http-server.props (the default server
identifier)
- All properties prefix should be removed (ie all http-server
prefixes)
- The AttributeHolder pickling format has changed:
- The FilteredResource pickling method had a bug (it didn't conform to
the general format)
- Before being dumped, attribute values are prefixed by theire pickled
length. This allows the unpickleInstance method to skip unknown (ie
deleted) attributes.
- The DaemonProperty
class is now only used as a property loader. It implements a catalog of
property sets; each ServerHandler
instance is responsible for managing its own ObservableProperties
instance.
- The getURL
method of User HTTPResource
instances now return the full path of the resource within any of the
server contexts (it used to return the full URL).
- The abstract Attribute class
now defines a new getPickleLength
abstract method (that has to be defined by sub-classes). This method is
used for the new pickling format of resources, to allow the unpickle
method to skip unknown attribute values.
- The ResourceStore
API has changed (for ResourceStore implementers only). The getVersion
method has been added, and must return the version of the class that
implements the store.
The initialize
method has a new opaque token parameter, to be used by the store
when calling back the resource store manager (eg when calling the
markModified method). The token can be thought of as the identity,
for the resource store manager, of the store.
- The HttpManager can
now be instantiated several times within the same process. This allows for
different context for the HTTP client side API. More precisely, the new
method getManager(Properties
props) will create a new manager if no other manager has been created
with that exact property set.
Bug fixes
- The CommonLogger now
initializes its buffer size properly from properties.
- Several fixes in the CacheFilter
(protocol implementation errors)
- Bug fixes in the server-side Request object, wouldn't
allow for non persistent connections.
- The new SocketClientFactory
now properly deletes old clients if needed (old clients would otherwise
tend to be priviledged wr to newer ones).
New features
Compatible API Changes
Jigsaw 1.0alpha3
A public release, made on October 7th, 1996.
This release is mainly a bug fix release with regard to the 1.0alpha2 release.
Bug fixes
Main bug fixes are:
- The HTTP client side code has been reworked. This shouldn't affect users
of that package, since it is mainly a rewritting of the internals of the
HttpManager. The main problem was the managing of persistent connections,
which is now much enhanced. The code was also cleaned up in that
process.
- The cache garbage collector really works now ! The 1.0alpha2 cache
garbage collector was just a proof of concept. The new garbage collector
works by chunking the flow of data being cache through generation
numbers, which allows for a much more precise garbage collections.
New features
A small set of enhancements has been made too:
- Virtual hosts capabilities have been added, this feature supports only
the Host based version of that feature (which doesn't consume IP
addresses). More documentation is available here.
- The ContainerResource
is now an abstract class, much more suitable for sub-classing then the DirectoryResource.
- The ProxyDirectory
now has a disconnected mode, which allows you to connect your
laptop from the net, get any numbers of document, disconnect from the net
