- jughead is a tool for getting menu information from various gopher
- servers, and is an acronym for:
- Jonzy's Universal Gopher Hierarchy Excavation And Display
-
- jughead was written in ANSI C, developed on an IBM RS6000, and
- should port easily to any ANSI C conformant environment.
-
- It is anticipated this program will be a tool for administrators
- in gopherspace. If you make any changes to the sources, please
- send me a copy.
-
- Release: version 0.5_beta, released:.
- Modified the code to support a secondary hash table. The table that
- gets read into memory is much smaller than previously, while the time
- to do the boolean operations and search the tables takes slightly longer, however, I doubt users will notice the difference.
- Note: This is a major change with the index tables. When running
- jughead with the -B flag, you no longer direct stdout to a file.
- What happens now is 2 files automaticlly get created, 1 with a ".ix" and
- the other with a ".ih" extention on the file created with the -b option.
- Furthermore when invoking jughead as a search engine with the -S flag
- you only need to give the name of the database file created with the -b
- flag.
-
- Release: version 0.4_beta, released: April 3, 1993.
- Added support for the 'a', 'A', and 't' options, which print the
- port host number of directories, port, host, the directories, and
- the time required to process a menu or build the index table or
- load the index table into memory respectively.
- Added the code from Mic Kaczmarczik: mic@bongo.cc.utexas.edu, which
- supports an optional -p port flag when running as a search engine.
- When using the -b option the datafile now gets sorted to remove all
- duplicates, and no longer gets written to datafile.sorted.
- The -o and -O flags are now meaningless and may soon disappear.
-
- Release: version 0.3.1_beta, released: March 28, 1993.
- Fixed a problem using vsprintf compiled on sun.
-
- Release: version 0.3_beta, released: March 28, 1993.
- Modifications include consolidating various #defines into the
- Makefile. Now keeps track of hosts we can't connect to and will
- not attempt to connect to these hosts again.
- Added support for compilation on a sun.
-
- Initial release: version 0.2_beta, released: March 25, 1993.
-
- jughead can be acquired via gopher by gophering to gopher.cc.utah.edu
- and looking in:
- About U of U Gopher
- Gopher Tools
- jughead
- as ReadMe and jughead.VERS.tar.Z
- or via anonymous ftp from ftp.cc.utah.edu in /pub/gopher/GopherTools
- as ReadMe and jughead.VERS.tar.Z, where ".VERS" is the current version.
-
- The file jughead.VERS.tar.Z is a compressed tar file which contains:
- dirTree.c
- Makefile
- jughead.1
- jughead.c
- search.c
- sockets.c
- dirTree.h
- tree.c
- tree.h
- utils.c
- utils.h
-
- Create yourself a directory for jughead, which should not be in a
- gopher data directory, and download the file jughead.VERS.tar.Z.
-
- Once you have downloaded jughead.VERS.tar.Z, where "VERS" is the version
- of jughead, the following command will uncompress and untar the files:
- uncompress -c < jughead.VERS.tar.Z | tar xfv -
-
- To view the man page, prior to running make install you can:
- make viewman
-
- To make the jughead application you should edit the Makefile and verify
- the following values are correct:
- THEVERSION The version of jughead, only edit this if you make changes.
- THECATCOMMAND The cat system command, the %s is required.
- THERMCOMMAND The rm system command, the %s is required.
- THESORTCOMMAND The sort system command, the %s is required.
- THETMPFILENAME The location and name of jughead's temporary file.
- THEPORT2USE The port to use when jughead is a search engine.
- DESTDIR The location of the jughead executable. You may not want
- this to be publicly accessible.
- DESTMAN The location of the jughead man page.
- VARARGS Commented out if you have <stdarg.h>.
- VSPRINTTYPE The type vsprintf() returns.
- PROTOTYPES Uncommented if you want to use prototypes.
- NOWARNINGS Uncommented if you don't want to see any compiler warnings.
- OPTIMIZATION Any optimization flags you want to have.
-
-
- Now do a "make", "make all", or "make install" to compile jughead. If
- you get any compilation errors please inform me of the problem.
-
- The steps I did to get jughead running as a server follow:
- jughead -tb data gopher.cc.utah.edu -x apogee.cc.utah.edu 3000 .utah.edu
- jughead -tB data
- jughead -tS data -l data.log &
-
- Create a link file somewhere in your gopher data directory. Mine looks like:
- Name=Search all UofU menus using jughead
- Numb=4
- Type=7
- Port=3000
- Path=
- Host=gopher.cc.utah.edu
-
-
- There exists a mailing list for discussion about jughead called:
- jughead-news@lists.utah.edu To get on this mailing list send
- mail to: jughead-news-request@lists.utah.edu
-
- Things still to do:
- 1) Allow a list of host exceptions, the hosts not to traverse.
-
- 2) Use the Path field in the link file to specify which database
- to use, load the database into memory, do the search, and
- release the memory. Maybe have this as an option.
- How about initialy start up with no tables cached in memory,
- when we receive a query read the appropriate table into memory
- if there is none, and only release the memory if a new query
- refers to an alternate database?
-
- 3) Add the ability to query other jugheads.
-
- 4) Consolidate the tree.c and dirTree.c files.
-
- 5) Either reenable or remove support for the -o and -O flags?
-
- 6) Clean up the code dealing with the hash tables or create a
- flag that does not utilize the secondary hash table?
-
- 7) Use vfork() instead of fork() when acting as a search engine
- to eliminate, as much as possible, any memory duplication.
-
- 8) Implement a no feed back flag which will give no feed back when
- building the hash tables, which will make the creation of the
- hash tables speed up by approximately 20 percent.
