Added `bin/bin/tar-entry.sh` to build a compressed tarball for an entry. The compressed tarball is formed by gnu tar with options so that the same entry file content will always produce the same compressed tarball, byte for byte. As some files are missing from some entries, one should use the `-W` option as in: ```sh bin/tar-entry.sh -v 5 -W 2020/ferguson1 ``` Added `make form_entry_tarball` to the top level `Makefile` to build entry tarballs even when files are still missing. Added `make verify_entry_files` to verify that all entries have all of their files listed in their manifest, plus the top level ioccc.css and var.mk files. As file entry files are still missing (due to HTML files that need to be built), the overall `make quick_www` and `make www` do **NOT** (yet) exit when the `make verify_entry_files` fails. Improved `bin/chk-entry.sh` by removing some variables that were not needed. TODO: Improve `bin/` tool exit codes as the current use is a bit silly. TODO: Clean out some variables used in `bin/` tools as some of then are only set printed in debug statements. TODO: Clean up usage messages, some of the options listed to not match the `getopts(1)` parsing. In some cases the option needs to be parsed but needs to be ignored by the tool because another tool automatically passes along certain options that really have no effect. Such ignored options need to be show as "This option is ignored" in the usage message.
Seventh International Obfuscated C Code Contest
Look at the README.md file for the given winning entry for information on how to compile it and how to run the winning program. Look at the winning source and try to figure how it does what it does! You may then wish to look at the Author's remarks for even more details.
This year, the Grand Prize won a standing ovation at USENIX.
The "Strangest abuse of the rules" award was given this year to stress the fact that starting in 1991, entries should be shell-specific.
This year was the first year that we accepted ANSI C entries. It was interesting to note that the ANSI C entries were as a whole less portable than the K&R C entries. We hope that in future contests people will enter more obfuscated and challenging ANSI C programs.
We would like to thank Barbara Frezza (loving wife of Larry Bassel) for her role as official chef of the contest. Her opinions regarding some of the contest entries were appreciated.
Rules and results were posted to comp.lang.c, comp.sources.unix, and alt.sources. They have been made available on a wide number of USENET archive sites such as uunet.
