Reduce use of master and other controversial words

[pinobatch]

During the COVID-19 pandemic of 2020-2021, I have taken up wearing two forms of protective equipment: a cloth face mask for source control and a hoop skirt for social distancing. A vocal minority of people object to face masks as a symbol of capitulation to radical Islamist totalitarianism and hoop skirts as a symbol of embracing antebellum slavery. I disagree with both.

To avoid calling to mind slavery even further, I'm looking for places in source code and documentation where I can rename "master" to "main", "trunk", "primary", or the like, per recommendation of the Inclusive Naming Initiative. Likewise, the allegedly ableist term "sanity check" can become "soundness check", "consistency check", "coherence check", or "confidence check". per Elian's answer.

To find these terms in my repositories, I'm running this command:

egrep -ri 'master|slave|stupid|retard|sane|sanity' . | cut -c 1-79 | less

Additional commands to find cases arising from particular project templates:

egrep -ri 'run_dma_master|master[-_ ]palette' . | cut -c 1-79 | less

These names are on a long-term allowlist:

• Sega Master System
• LAN Master by Shiru,
• Insane Game by Martin Hock
• Sanity meter in Eternal Darkness
• Duel Masters Trading Card Game by Wizards of the Coast and Tomy,
• "Master of Puppets" by Metallica, "Wishmaster" by Nightwish

I also have a short-term allowlist until the initiative endorses replacements:

• webmaster
• Interrupt Master Enable (IME), the setting controlled by di and ei instructions in Intel 8080 and derivatives (Z80, SM83)
• "master clock" of 21.48 MHz on NES and Super NES or 53.69 MHz on Genesis
• "mastering" of audio
• "Game master" in tabletop RPGs and "Dungeon Master" in Wizards of the Coast's Dungeons & Dragons
• "stupid statement dance mix" as defined by TV Tropes and All The Tropes

And a second short-term allowlist until public repository hosts get tooling in place:

• master branch in Git

Once IME is renamed, Pently's "master" switch to shut off the music portion of the sound driver can also be renamed.

These terms were removed in April 2023 after INI issued a clarification about "mastermind" and "master inventor", which clearly refer to skill rather than dominance over a subordinate entity:

• Codemasters, Bitmasters
• Kick Master by Taito, Blaster Master by Sunsoft, Little Nemo the Dream Master by Capcom, Chessmaster by Ubisoft, Kung Fu Master by Irem
• Captain N: The Game Master by DIC
• Othello board game tagline "A Minute to Learn, A Lifetime to Master"
• Bassmaster tournaments by Bass Anglers Sportsman Society
• "master-builder" in M. T. Cicero's De finibus and The LEGO Movie
• "Master D" in Bionic Commando and "Master Y" in STREEMERZ
• master's degree, Master of Science, Master of Arts

What do we call the flip-flop in the 8080, Z80, and SM83 that di sets to 0 and ei sets to 1, or the register at 0x04000208 in the Game Boy Advance that turns interrupts on and off?

• Intel 8080 datasheet calls it "the internal interrupt enable flip/flop" and outputs it on the INTE pin.
• Zilog Z80 datasheet calls it IFF1 (Interrupt Flip Flop 1), where there's also an IFF2 for saving IFF1 on entry to NMI and restoring it on exit.
• Sharp Microcomputer Databook 1996 calls it "Interrupt master enable flag IME".

During research for this, I awarded Inclusion Cookies™ to members of the gbdev server for backronyms:

• :cookie: to MR9K for "interrupt mechanism enable"
• :cookie: to Daid for "interrupt mask enabled"

I replaced run_dma_master originating from a project template for Game Boy with hramcode_start. To open an editor ready to do this, I ran this:

find -name "*.z80" -exec egrep -Zli 'run_dma_master' {} + \
    | xargs -0 mousepad &

Explanation of command-line syntax:

• find -exec ... {} +: run program once with results as arguments
• egrep -Z, xargs -0: terminate filenames with \0 instead of \n
• egrep -l: print only filenames
• egrep -i: ignore case

In April 2023, the words "mastermind" and "master inventor" were spotted on the "no change" tier of Inclusive Naming Initiative's word list. The entries for these terms state that each term "refers to a level of skill rather than a dominant/subordinate relationship."
