Vargas Caballero Date: Tue, 28 Oct 2025 21:21:11 +0100 tests/make: Reduce the timeout for 0102-signal This timeout never had to be changed, because changing it was only hiding the actual problem, which was a race condition due to the incorrect signal handling.

libc/malloc: Unify malloc and realloc

commit 2a2e57ae043b6d78a5dbd50761971d6508540729 parent 2b33af36beceaf67507ab881f113d68a371a4f13 Author: Roberto E. Vargas Caballero Date: Tue, 17 Jun 2025 20:16:23 +0200 libc/malloc: Unify malloc and realloc realloc(p, 0) should behave like malloc(0), but we were not setting the same errno values, and we were returning NULL in both cases, that makes more difficult to differentiate the case when 0 is passed and the case when we don't have enough memory. Given that the traditional behaviour was always to return a pointer that could be freed (and even that was the original behaviour in scc) this commit restores that behaviour.

Given this situation, the saner decision is to define it as a recursive macro with one argument that expands to itself.

Vargas Caballero Date: Fri, 28 Mar 2025 09:42:13 +0100 libc/wchar: Simplify mbsrtowc() and mbstowc() We only support UTF8, that is stateless, and as mbsrtowc() cannot return -2 then we do know that the internal state of mbsrtowc() will be always set to the initial state, so we can reuse it from mbstowcs(). Also, mbsrtowcs() had a bug and it was incrementing the number of wchar stored in the output buffer when mbrtowc() returned -2. Not a big issue because we try to read MB_LEN_MAX, and longer sequences will eventually return -1 and the value of n will not be used.

libc/wchar: Remove state from mbtowc()

Vargas Caballero Date: Thu, 27 Mar 2025 22:11:35 +0100 libc/wchar: Remove state from mbtowc() As we only support utf8 it does not make sense to keep state in mbtowc() because as we cannot differentiate between an incorrect sequence and a non complete sequence then there is not actual use case for that state. We still keep the static variable because we don't want to use the internal state from mbrtowc(), and as this function is not safe thread anyway it is not a problem to have that variable, whose value will be always correct, except when mbrtowc() returns -2 and in that case we have to clear it. The C99 specification does not specify any errno value when mbtowc() fails, but it allows changes to errno even when it is not directly specified in the standard, so it is not a problem to implement mbtowc() using mbrtowc() which sets errno when it cannot translate a full multibyte sequence.

Vargas Caballero Date: Mon, 10 Mar 2025 21:22:52 +0100 libc/wchar: Rewrite mbtowc() There are many different corner cases in the implementation of the underlaying call to mbrtowc(). When mbrtowc() returns -2, it should be ready to receive new bytes with new calls, and it requires to update the conversion state. Also, the standard specifies: The implementation shall behave as if no library function calls the mbtowc function. and for that reason, we cannot pass a NULL pointer as state to mbrtowc() because it would imply to use the hidden state of mbrtowc(). After considering to keep ABI compatibility with the definiton of mbstate_t in the different systems, it created to many problems. There is 0 guarantees that code compiled with different libc implementations would work, and for that reason we dropped the ABI compatibility.

The simpliest way to solve the situation is to hardcode the number 4, because other solutions would need an internal macro (for example, _MB_CUR_MAX) that is converted to MB_CUR_MAX if stdlib.h is included. Anyway that solution still have problems, because this affects to the ABI of darwin, so our changes to MB_CUR_MAX should not affect to this ABI.

libc/wchar: Define mbstate_t correctly

2025-03-04T18:45:27Z

commit ab077b6a7eb4f2d524d5cd53c49a3dde531cde4a parent 3eedc954682df1ec5b47667cc27a9ab69642e7b1 Author: Roberto E. Vargas Caballero Date: Tue, 4 Mar 2025 19:45:27 +0100 libc/wchar: Define mbstate_t correctly The definition of the mbstate_t type depends of the target platform, and it should be defined in the sys/cdefs.h files.

libc/wchar: Add mbsinit()

2025-02-26T09:14:10Z

commit 3eedc954682df1ec5b47667cc27a9ab69642e7b1 parent 21df8da7aed52515d5149538a9a1c5d622e4a166 Author: Roberto E. Vargas Caballero Date: Wed, 26 Feb 2025 10:14:10 +0100 libc/wchar: Add mbsinit() As we only support utf8 for multibyte streams the implementation of mbsinit() is trivial because utf8 is stateless.

libmach/elf: Add elfrel.h

Vargas Caballero Date: Thu, 20 Feb 2025 11:39:30 +0100 libmach/elf: Add elfrel.h This file was missed in a previous commit and the build was broken but it was not catched by the developer builds.

libmach: Use long for offset

2025-02-20T09:31:50Z

commit e776065632d998cb8491dded4d3c809ac272f5fc parent 11f2d4ad18c54ed4b3147efb7554820173edd38c Author: Roberto E. Vargas Caballero Date: Thu, 20 Feb 2025 10:31:50 +0100 libmach: Use long for offset As we use standard fseek() and ftell() we cannot support files that cannot be addressed with longs, so it is better to check for these problems when reading files and use long after that point.

objdump/elf: Add support to print segment/section mapping

2025-02-19T17:33:25Z

commit d0509114ad684f71ca106b6a984b00045cfe70b9 parent 079de338d0a2d275671d12756e4349f17d1b927d Author: Roberto E. Vargas Caballero Date: Wed, 19 Feb 2025 18:33:25 +0100 objdump/elf: Add support to print segment/section mapping Elf makes a difference between segments and sections, being segments the in core representation, while sections the linker representation. Segments include into its memory space the content of the sections and it is important to know what sections are covered by one segment, being possible that a section is covered by more than one segment.

libmach: Rewrite the mapping functions

commit 079de338d0a2d275671d12756e4349f17d1b927d parent b66f5506b858ae66635d27988ee9d4dd7e0471e6 Author: Roberto E. Vargas Caballero Date: Wed, 19 Feb 2025 18:16:32 +0100 libmach: Rewrite the mapping functions The support for elf requires to include the segment to section mapping, and it requires a deep rewrite of the mapping functions and how we build the map.

libmach: Remove Segment data type

2025-02-19T16:23:54Z

commit b66f5506b858ae66635d27988ee9d4dd7e0471e6 parent 7b4fef3358a0397fe10577d0b0ce55399953ab7d Author: Roberto E. Vargas Caballero Date: Wed, 19 Feb 2025 17:23:54 +0100 libmach: Remove Segment data type The difference between segments and sections was mainly for elf, which differentiatels between them, but the attributes from the abstraction point of view are the same, so we can use only one data structure but different functions. As the linker does not merge any sections yet, we can just comment out the merge function and nothing changes.
