Vargas Caballero Date: Tue, 25 Nov 2025 16:54:04 +0100 bc: Use dynamic memory for strings Until now bc was using a clever mechanism that built all the strings in a single buffer that makes very easy handling them because no free was required. but it had a big problem because the size of the space used in this buffer grew exponentially because new strings were containing previous strings and all of them were living in memory at the same time. This new mechanism implements a printf alike and when strings are used as parameters it frees them, but it implies that we cannot use anymore constants as parameters and in some specific cases we have to free them manually.

Vargas Caballero Date: Sun, 23 Nov 2025 20:34:34 +0100 bc: Implement return statements When a return is found we have to go out of all the nested contexts and _ideally_ that number should be in nested, but we are including the function contexts here. Also, this makes clear that the implementation of break was wrong, because we have to find the nesting level of the previous loop to break it. Also, at this moment no semantic check is done to vaalidate that we are in a loop or even in a function, and it means that weird things can happen if we put a return out of a function scope.

grep: Don't modify constant strings

commit ae7bfda8f6f1b3f1951e8e69b8910d5171bf6236 parent 87f4755cd09eecdab7c750a347143cc6fb3b262d Author: Roberto E. Vargas Caballero Date: Wed, 5 Nov 2025 09:59:44 +0100 grep: Don't modify constant strings The pattern pointer was assigned to a constant string and later it was modified, which is UB. But even worse, as we were trusting the patlen parameter received, patlen was meaningless after that assignment. The addpattern() had many problems because it trusted the patlen parameter, but in some places it used string functions that depend of having a NUL character creating many problems when embedded NUL characters were found in the pattern. As mandated by POSIX in [1]: The interfaces specified in POSIX.1-2017 do not permit the inclusion of a NUL character in an RE or in the string to be matched. If during the operation of a standard utility a NUL is included in the text designated to be matched, that NUL may designate the end of the text string for the purposes of matching. so, the simples solution is just discard the patlen parameter and call strlen() in addpattern() and use that as size of the pattern.

Use a temporary buffer for SHA-512/224, as 224 is not multiple of 64-bit internal state array of SHA-512.
