shell: update HISTFILESIZE code to be actually useful

2025-07-03T17:10:42+00:00

"HISTFILESIZE=0" in profile wasn't working as intended, "unset HISTFILE" wasn't preventing creation of history files Now: HISTSIZE=n allows to reduce in-memory history buffer HISTFILESIZE=n allows to reduce history file size (0: truncate it) unset HISTFILE allows to not save history file at all function old new delta exitshell 138 194 +56 hush_exit 97 143 +46 save_history 266 296 +30 hush_main 1170 1186 +16 .rodata 105762 105771 +9 load_history 246 254 +8 size_from_HISTFILESIZE 44 41 -3 read_line_input 2746 2712 -34 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 6/2 up/down: 165/-37) Total: 128 bytes Signed-off-by: Denys Vlasenko

Use Windows library for cryptographic checksums

2025-06-09T12:23:49+00:00

Add a new feature to libbb, FEATURE_USE_CNG_API, which enables the use of the Cryptography API: Next Generation library to calculate checksums. It is disabled by default except in the mingw64u default config, as the API requires Windows 10+ to function. Usage of this API provides a size benefit and delegates hardware optimizations to the operating system cryptography library. Based on GitHub PR #498 by rfl890. Saves 4064 bytes in the mingw64u case.

libbb: make default history size configurable

2024-04-28T13:19:51+00:00

Allow the default history size (used if HISTFILESIZE isn't set) to be configured at build time. This may be less than or equal to the standard history size. (GitHub issue #411)
