solver3: Avoid FTBFS with g++ 14.2 on arm{el,hf}

2025-06-10T18:51:09Z

With an explicit {} initialization, g++ 14.2 on armhf and armel seems to generate the default constructor for the vector too early, or in the first place, outside of solver3.cc where the constructor is defined. Without {}, this compiles again.

Revert "doc: Increase visibility of special signs' usage"

2025-06-10T16:03:00Z

This reverts commit 66ec0dfad8ac1d4d8646a4734eb9353f3ebc0a91. This creates too much churn in the translation.

Avoid cast alignment warning in cache string view

2025-06-10T15:29:33Z

The cache allocates strings as uint16_t size; char content[]; char zero; Aligned to the uint16_t. When doing the casting, this causes a warning on some architectures that cannot do unaligned loads, such as armhf. Use __builtin_assume_aligned() to explictly say that the pointer is aligned to 16 bits. This is a bit of a backhanded approach, as the warning seems to be actually avoided by the function returning a void* rather than the assumed alignment, but this is very much self-documenting.

solver3: Filter installed Recommends

2025-06-10T14:27:36Z

When inspecting Recommends of installed packages, filter them to the installed packages only, as we want to avoid switching between alternatives of recommended packages.

solver3: Explicitly declare and define ~Solver

2025-06-10T14:27:36Z

On recent armfhf and s390x builds in the PPA, the compiler seems to have generated the destructor at the wrong point where the definitions where not yet complete, and it does seem ill-advised to rely on a default-constructed destructor in the solver for future ABI sake.

solver3: Ignore Architecture: all for obsoleted-by

2025-06-10T14:27:36Z

In case a new version of the source package is published, we check that if there's a newer binary for the same architecture and then consider the binary obsoleted. This logic did not properly account for Architecture: all packages which are considered as native architecture package with an "All" multi-arch flag set, and hence a native architecture package may inadvertently be considered obsoleted by a package that only built on Architecture: all.
