4.4BSD/usr/src/contrib/news/trn3/nntp/nntp.patch
Here's my latest patch to modify NNTP 1.5.11 to support the transmission
of thread databases.
This patch supports both mthread's .thread file format (XTHREAD) and News
OVerview's .overfile file format (XOVER). It also adds the LISTGROUP
command for listing the numbers in a group, and the DATE command for
finding out the time on the server. Finally, the NEWGROUPS command is
filtered based the user's access privileges.
Apply this patch from the root directory of your NNTP source. While it
only affects your server (the clientlib is no longer modified), it does
modify things in the common directory.
To apply this:
cd nntp-1.5.11
patch -p < xthread.patch
OR unipatch < xthread.patch | patch -p
This patch changes the conf.h.dist file, so you will need to edit your
conf.h file to add the new defines. For example, you could:
cd common
diff -c conf.h.dist.orig conf.h.dist | patch conf.h
and then edit conf.h to make sure the new stuff is configured properly.
Then you are ready to compile the new server with "make server" as usual.

since the initial release. Individuals who either reported the bug or
inspired the bug fix are in square brackets.
+1.5.11+XOVER1 (Wayne Davison <davison@borland.com> 18 Jan 93)
+ Fixes, optimizations, and enhancements to the first patch.
+
+1.5.11+XOVER0 (Rich $alz <rsalz@uunet.uu.net> 23 dec 92)
+ This adds the XOVER command to the server. The XOVER command
+ is used to retrieve data from the .overview file that is part
+ of Geoff Collyer's "nov" package (that package is not provided
+ here; the official archive for it is
+ world.std.com:pub/src/news/nov.dist.tar.Z). This command
+ has the following syntax:
+ XOVER [first[-last]]
+ Where first and last are article numbers; the default is to
+ return data for the current article. This command is only
+ valid after a GROUP command. It returns a 224 code followed
+ by a multi-line response.
+
1.5.11
Fixes to spawn.c and batch.c for those system that need
execle() to specifically call /bin/sh to exectute a sh script.
