The server transmits 1 nibble at a time by counting to the nibble value via a sequence of rapid responses terminated by a long response.

The long delay is skipped in the case of 15, the maximal nibble value. With the aid of an ASCII table, it is actually possible to read the nibbles by repeatedly pressing the refresh button within a browser and observing the page refresh delay. +The client-side downloader relies on the response time of the web server rather +than the binary content of the response.

Decrease the value to download faster and less reliably. +As with all network communication, accurate transmission of data relies on the +nature of hardware revealed through statistics and timeouts set accordingly. +The long delay is arbitrarily set to `0.5` seconds.

Without this fix the entry did not work. +Cody fixed this for modern systems (it did not work at all) and added an +alternate version that works with macOS. Cody also made it ever so slightly more +portable by removing the hard-coding of `gcc`, instead hard-coding it `cc`. Doing +this not only lets it work with systems without `gcc` (though in macOS it does +exist but is actually `clang`) as `cc` always should. -What was wrong? The call to `freopen()` was incorrect with the second arg (the -mode) being instead `5+__FILE__`. It now is `"r"`.

He -notes that it works fine with `clang` as well as `gcc` (which is what is used -but in macOS - see below for alternate code - `gcc` is clang). +Getting this entry to work was quite complicated but is also very interesting. +To see how the macOS fixes works, see the README.md but do note that this +includes spoilers for both versions! The fixes to get it to work at all are +described next. -Additionally Cody provided an alternate version for macOS. The fix is -rather complicated but very interesting. See the README.md file for details on -how it works and how to use it. +So what was wrong with the original? + +The call to `freopen()` was incorrect with the second arg (the mode) being +`5+__FILE__`; it is now `"r"`. (Observe that the mode to the `fopen()` +call is: `44+__FILE__`. This might seem incorrect and indeed it can be changed +to `"r"` as well but this was not actually necessary so once this was noticed it +was changed back to the original.) + +Another important change is that the files are only closed if the `FILE *H` is +`!= NULL`. Without this check, because it's almost certain that some files will +not exist, it would dereference a NULL pointer and very likely crash or halt and +catch fire :-), preventing the entry from working. Notice how `H` is a funny +macro defined as: + +```c +%:define H(x) +``` + +and yet the `FILE *` can be called `H`! This might or might not make sense to +you but if it doesn't can you figure out why? + +Another fix is that previously the program would `return 1` if a file failed to +open but for the same reason as above, it being very likely some files will not +exist, the return was removed so that if the statement of the `if` is true the +`while` loop run, rather than having the loop by itself. It was done this way to +make it as close to the original as possible and to maintain the obfuscation as +close as possible as well. + +Also crucial, and the final fixes to make it work, is that the arrays `K` and +`L` had to be increased in size. They were originally (somewhat bewildering at +first glance) defined as `K[X(*)], L[X(<<)]` but they were changed to +`K[(X(*))*4], L[4*X(<<)]` though it is no longer clear just how necessary this +might be. + +As noted, a limitation of `gcc` existing was removed by Cody to make it so that +`gcc` is not required as `cc` should exist in every system with a C compiler and +as the author stated: as long as the options `-E -dM` of the compiler prints out +the macros in the form of `gcc -dM` i.e. the lines are in the form `#define +MACRO value` it will work, assuming that compiler can run, of course. + +As for the version for macOS, the even more complicated details are described in +the [Alternate code](1998/schweikh1/README#alternate-code) section of the +README.md file as these changes pertain to the described version therein. ## [1998/schweikh2](1998/schweikh2/schweikh2.c) ([README.md](1998/schweikh2/README.md])) @@ -989,6 +1049,12 @@ segfault when run or not compile at all (gcc and clang respectively).
