…flow warnings from GCC (HDFGroup#1706) * Avoid a signed overflow: check the range of `entry_ptr->age` before increasing it instead of increasing it and then checking the range. This quiets a GCC warning. * Avoid the potential for signed overflow by rewriting expressions `MAX(0, fwidth - n)` as `MAX(n, fwidth) - n` for various `n`. This change quiets some GCC warnings. * Change some local variables that cannot take sensible negative values from signed to unsigned. This quiets GCC warnings about potential signed overflow. * In a handful of instances, check the range of a signed integer before increasing/decreasing it, just in case the increase/decrease overflows. This quiets a handful of GCC signed-overflow warnings. * Committing clang-format changes Co-authored-by: github-actions <41898282+github-actions[bot]@users.noreply.github.com>
Hyperslabs can be reworked inside several H5S callbacks, making H5S_t non-const in some places where it is marked const. This change switches these incorrectly const H5S_t pointer parameters and variables to non-const where appropriate.
