macOS Homebrew

More adjustments to accommodate Homebrew: this time passing the location of the Splatalogue SQLite file and the "htdocs" directory.

macOS Homebrew

• macOS: adjusted the gcc/gfortran compiler path so that a Homebrew formula uses gcc/gfortran from the Homebrew repository instead of Apple's clang, which that does not contain OpenMP support.

macOS Homebrew

• macOS: adjusted the Makefile in order to improve setting the Homebrew prefix (a fix needed when compiling from within a Homebrew formulae)
• added a MAGIC_NUMBER to the binary cache file in order to handle automatically any cache file format changes (the cache directory content will now get invalidated automatically)

Maintenance

• Another binary cache disk format change: removed the redundant item%uri field from {save, load}_dataset(). item%uri is set to a new value each time upon opening a FITS file.
• Added a staging step NFS-->glusterfs to the preload fitsDB.jl Julia program.

Maintenance

• Switched over to the Content Delivery Network (CDN) for the WASM files.
• Added the missed create_root_path() functionality for the server edition.
• The binary cache disk format has changed: the storage switched from real(kind=4) to real(kind=8) for the floating-point fields read from the FITS header. This was done in order to improve the precision of frequency/velocity calculations.

Maintenance

• recompiled WebAssembly with the latest emscripten
• switched to proper versioning with specific dates instead of XX.X
• a minor bug fix

Improved POSIX threads support on macOS

• replaced fortran-unix pthread bindings by custom FORTRAN bindings (via a custom C bridge) to POSIX threads that work properly on macOS as well as Linux
• added multi-threaded "tileLanczos" and "tileSuper" image downsizing functions using Intel IPP (Linux only, macOS uses Apple Accelerate instead)

Optimisations

• Speed improvements in image downsizing.
• Switched to Apple Accelerate vImage on Intel macOS too (not just on Apple Silicon).
• Improved support for large-resolution FITS images / cubes (for example width = 30000, height = 20000).

the first stable BETA

• optimised native Apple Silicon support (using macOS Accelerate vImage for downsizing images)
• for now only a single-dataset view is supported
