Jigsaw

Jigsaw known bugs

The current list of bugs has been splitted into three lists:

• Jigsaw specific bugs is for bugs in Jigsaw code
• Platform specific bugs is for known bugs on certain platforms
• Limitations

Jigsaw specific bugs

The list of Jigsaw bugs. This list gives all the bugs in Jigsaw Java code. They should be fixed in following releases.

• AuthUser
  Its editor - /Admin/Realms/realm/user - shouldn't allow to change user's IP mask since this breaks the ipmatcher (which isn't updated for good reasons). Work-arounds:
  • Restart the server after some user IP address edition (using the /Admin/ServerProperties resource)
  • Delete/re-create the user record instead of editing its IP address.
• GenericResourceEditor
  The generic editor allows for editing the resource identifier, but doesn't inform the store manager that its indexing key has change (solution same as above)
• NegotiatedResource.
  Content negotiation interfers with IMS request: I am still unsure of were the bug is, but here is the situation: write two files foo.fr.html and foo.en.html, create a negotiated resource to negotiate among them. Using netscape (at least), ask for foo, you will get the right variant, then change you language settings ask for foo again, you will get back a NOT_MODIFIED potentillay applying to the other variant.
• Jigsaw is unable to run on a port number less then 1024, except if you run it as root (which is not recommended). Future release will include the piece of native methods to change Jigsaw personnality upon startup.
• CvsDirectoryResource
  Sometimes, the CVS process exists with a status of 1. I suspect this is a Java bug (although I am still unsure), see the ProcessFilter bug too.
• ProcessFilter
  The process filter unfortunatlley doesn't work. I have spent more then an hour trying to dig out the bug (which has to do with exec), with no luck. I suspect a Java bug around here.
• httpd
  Restart doesn't work on Windows95. The client pool shutdown waits for client threads to terminate, and doesn't get notified of their death (through Thread.join). I suspect yet another java bug here.

Platform specific bugs

This list gives the platform specifics bus. Most of them are due to early Java implementations on the various platforms, and should be corrected in next Java releases.

Windows 95
WindowsNT

Bugs specific to the Win* platforms

Solaris 2.x

Bugs specific to the solaris platform.

• Process management under UNIX doesn't work properly, this will affect mainly the ProcessFilter class, and probably (although I have no evidence of this), the CgiResource class.

Limitations

Things that Jigsaw internals allow you to do, but that are not available through the form-base configuration GUI. These should be fixed in next Jigsaw releases.

• Although, internally Jigsaw allows you to put any number of filters on a resource, the user interface doesn't allow you to plug two different instances of the same (were same means same Java class) filter.
