Entry source is now prog.c for IOCCC years 2014 thru 2020,
or is now dirname.c IOCCC years 1984 thru 2013.
To achieve this state, we renamed the following:
renamed: 2004/hibachi/src/hibachi.c -> 2004/hibachi/hibachi.c
renamed: 2012/omoikane/nyaruko.alt.c -> 2012/omoikane/omoikane.alt.c
renamed: 2012/omoikane/nyaruko.alt2.c -> 2012/omoikane/omoikane.alt2.c
renamed: 2012/omoikane/nyaruko.c -> 2012/omoikane/omoikane.c
renamed: 2012/omoikane/nyaruko.orig.c -> 2012/omoikane/omoikane.orig.c
Modified `bin/subst.entry-index.sh` to add to entry `index.html` file,
links to the `Makefile` and the _C code_ to the top navigation bar.
Changed `bin/subst.entry-index.sh` VERSION from "1.2.2 2024-02-25"
to "1.3 2024-03-02".
Moved printing the Inventory link in the top navigation bar
from `bin/subst.entry-navbar.awk` to `bin/subst.entry-index.sh`.
Changed `bin/subst.entry-navbar.awk` VERSION from "1.0.1 2024-02-23"
to "1.1 2024-03-02".
Moved printing the Inventory link in the top navigation bar
from `bin/subst.year-navbar.awk` to `bin/subst.year-index.sh`.
Changed `bin/subst.year-index.sh` VERSION from "1.0 2024-02-11"
to "1.1 2024-03-02".
Changed `bin/subst.year-navbar.awk` VERSION from "1.0 2024-02-11"
to "1.1 2024-03-02".
Added location names (both default and common) to `author.html`.
Changed `tmp/gen_author_json.sh` VERSION from "1.0 2023-06-06"
to "1.1 2024-03-04".
Added location names (both default and common) to `author.html`.
Changed `bin/gen-authors.sh` VERSION from "1.2 2024-03-09"
to "1.3 2024-03-04".
The manifest and the resulting `.entry.json` files have been changed
for `2004/hibachi` and `2012/omoikane`.
The Makefiles for `2004/hibachi` and `2012/omoikane` copy the
source file into the "previously used location". The `make clobber`
rule removes the copied source. The `.gitignore` files have been
updated accordingly.
Improved how the concept of IOCCC terms _entry_, _author_ and _submission_ are
used in markdown files.
Links to markdown files (files ending in .md) within the repo were
changed to link to HTML files (files ending in .html). Special cases
where `README.md` became `index.html` were modified accordingly.
Fixed URL for `bugs.html` in Makefile comments.
Fixed name of `bin/sgi.sh` referenced in comments in `.gitignore` files.
Links to locations within the repo are now relative. For example a
link to `/contact.html` may become `../contact.html' or '../../contact.html`
depending on the directory level of the markdown file.
Nearly all links with absolute URLs under _https://www.ioccc.org_
or `https://ioccc-src.github.io/temp-test-ioccc_ have been changed to
relative paths within the repo. Some exceptions to this (such as
referring to a GitHub repo) were preserved.
Fixed a number of inside `faq.md` and `bugs.md`.
Added HTML name tags (in the form of an _entry_id_) for each entry
referenced in `bugs.md`. Fixed links from outside of `bugs.html`
into `bugs.html` accordingly.
Where FAQ entries are referenced, a named tag is used so that if a
FAQ is ever renumbered, links outside of `faq.html` will still work.
Changed the _inventory_order_ of a compressed tarball from _300_
to _100000_. While this may have been done for the manifest,
this changed had not yet been propagated into the `.entry.json` files.
Links to web sites that were in the for <URL> are now [URL](URL).
Performed `name www` to process all of the above.
Improved format of `authors.html`. Full names are now bold.
Location codes are now links back into `location.html` and
location names (both default and common) are now italics.
Added _author_handle_ each author.
Changed `bin/gen-authors.sh` VERSION from "1.1 2024-02-25"
to "1.2 2024-03-09".
Improved format of `location.html` as location codes are now bold,
author counts in a given location are now bold, and location names
(both default and common) are now italics.
Changed `bin/gen-location.sh` VERSION from "1.0.1 2024-02-23"
to "1.1 2024-03-04".
Added italic location name after location code in entry
`index.html` files.
Changed `bin/output-index-author.sh` VERSION from "1.4.1 2024-02-23"
to "1.5 2024-03-04".
Added _Location of authors_ to the sidebar as a link to `location.html`.

The 64-bit code binaries have been renamed to .alt: anonymous.ten.alt
and anonymous.bed.alt. This is because it's theoretically possible that
they are not compiled as 64-bit binaries (though how this might be I
cannot think of at this time) and in any case they are alt builds
(though they use the same source).
In the case the -m32 fails (whether due to compiler[0] or no access to
32-bit binary compilation) make alt will be used with warnings that the
entry cannot work with them. The reason these are built as .alt and not
the original is to be clearer whereas in other cases (like
1985/sicherman) the point was just a backup plan in case a compiler
objects to it. Here they must be compiled as 32-bit ELF binaries (though
we cannot check if they are ELF - at least not easily and in an entirely
portable way - we can at least determine if they compiled as 32-bit) so
the alt builds are set to be .alt in filenames.
The try.sh script has been updated for this and in the case. However
this file needs to be looked at again and will be later. The purpose of
this commit was to resolve another issue that is in the todo file (this
is not yet done and might or might not be done later today).
fix experimental web site links in experimental index.html
sync CNAME with https://github.com/ioccc-src/winner/blob/master/CNAME
improve .gitignore files
Added to each .gitignore file, comments on how to sort.
Put into winner .gitignore files, ignore *.dSYM files.
Put into winner .gitignore files, ignore indent.c,
indent.o and indent files. This is done so that the
winner directory can more self contained.
We did not put into winner .gitignore files, however,
excludes of .-files as found in the top level .gitignore file.
As .-files are not allowed by mkiocccentry, the top level
.gitignore file remains sufficient.
Added to year level .gitignore files, excludes of
mkentry or iocccsize files as needed.
Sorted (via sort -d -u) all .gitignore file.
Due to the fact we now have .orig.c files and thus the possibility of
winner.orig or prog.orig being built I have updated all the .gitignore
files so that these files ignored. This was done with the following
shell commands, for reference:
for i in $(find 19* 200* 201[0123] -mindepth 2 -maxdepth 2 -name .gitignore) ; do echo $(dirname "$i"|sed -e 's,[0-9]\{4\}/,,g').orig >> "$i"; done
for i in $(find 201[4-9] 2020 -mindepth 2 -maxdepth 2 -name .gitignore) ; do echo prog.orig >> "$i"; done
and the two commands is because it was only in 2014 that the winning
entries were renamed to prog so prog.orig is the correct glob.
This sings a different counting song, Ten in the Bed. It uses another C
feature (a char *[]) that the Ten Green Bottles does not use. This is
for fun as well as to show another program (with a different C feature)
that the program works on, again assuming -m32 is allowed.
Instead of using numbers it uses strings (as expected with a char *[])
in the singing.
This was for fun (and to see if the program would work on arrays) after
I remembered the song in a comment on GitHub - about the Ten Green
Bottles song.
Running make alt will compile the anonymous.ten.c without specifying
-m32: whether it'll end up being 64-bit or not would depend on the
system but it'll be saved as anonymous.ten.64 anyway.
The try.me.sh script will run this program directly, skipping the entry
itself, if the anonymous.ten.c cannot be compiled as a 32-bit binary.
Updated .gitignore.
I can now report happily that the program works as it was thought to -
both modify the binary and run it. A problem was that it used to call
main() infinitely (seemingly) call main() recursively but this was
causing a problem. It had to be (as I did some while back) moved to a
new function which is not recursive. My guess is that in the past it was
okay due to exit() but I don't know if this is true or not. So what
could be done?
We have to make sure we have BOTH the file descriptor AND the mmap()d
memory close()d and munmap()d as otherwise we would get a text file busy
error. Then we simply call execv() again. I didn't change it so that the
earlier call to execv() is no longer called because I didn't want to
break anything even though at that point M is actually empty.
The astute programmer would observe that the execv() call is slightly
different: don't use M as the path but rather k[1]. Why? Because
initially M is empty but after the function is called it ends up being
something like '.anonymous.ten134517173' but this file never exists. If
you observe even no file is created (or so it seems) as only cpp is
used, not cc (I'm not actually clear what the purpose of that is). The
mmap() call is important of course as is the open() call as one of the
parameters of mmap().
Is this a workaround? Perhaps in a way but it's the only way it'll work
that I can think of as munmap() and close() must be called lest we get a
text file busy error and only then can we call execv().
Removed cpp.c and cpp make rule.
Using a script running ./anonymous will run the program after modifying
it. This is a temporary workaround and it's not certain when this will
be changed back or fixed if it even can be. I am aware of some things
that might make it work IF it actually IS supposed to run the program
that it's run on (an additional reading of README.md suggests this might
indeed be the case). In any event the entry DOES modify 32-bit binaries
(bit twiddling) and then running the script (made a copy of
anonymous.sh where anonymous.c is compiled to anonymous_tmp) it will run
the program after doing this, assuming that the program to modify
actually exists.
It should be noted that because things have changed so much it is hard
to know if the modifications to 32-bit ELF binaries are correct but if
nothing else the binary will not crash on 32-bit ELF binaries and it
will modify it but still let it run (though from the author's comments
this might not be possible; this cannot yet be confirmed). Leo it
appears wrote the judges' comments so I will try and get more
information from him later on.
In order to know what had to change exactly I tested this out (though
it's possible I forgot to initially document changes and so I did not
test everything) and I have documented it in the README.md. The required
changes:
- remove infinite recursion from main(): move the body of main() to
another function.
- add #include <sys/mman.h> for mmap().
Without either this did not work. I also changed (in case of
non-standardised constants) '3' in the call to mmap() to be
PROT_READ|PROT_WRITE but this appears to not be strictly required.
I added the script try.me.sh which has more commands than the previous
try section to show how it works and what changes etc.
Updated .gitignore as the above script creates some.
Make make all attempt to compile anonymous.ten.c: it's an important part
of the program though it can work on other 32-bit ELF binaries.
Update bugs.md explaining why this won't work with macOS.
Format fix in README.md.
Add cpp.c which is the C pre-processed version cleaned up and somewhat
commented as it heavily (ab)uses the ternary operator and recursion.
Probably futile but it gave me something to do even if it was a waste of
time (could have worked on other README.md files or a host of other
things). This did indeed take a long time and a lot of effort!
Updated bugs.md with more hints about this entry. I explained here how I
came up with the C pre-processed version as it involves something of a
hack because of the complicated build instructions.
Updated anonymous.ten.c: #include <stdio.h>
Added anonymous.ten rule to Makefile.
Also disabled optimising level as the author stated that this makes it
slower.
I observed that the author is anonymous and yet the author information
shows the country. I'm not sure if this is intended or not.
Add to anonymous/.gitignore 'anonymous.ten' as that's the example
program to be used for the entry (to those who want to try and fix it).
Minor fixes to three README.md files.
