Git identity — always use chirag127's GitHub noreply email

chirag127 noreply email for all commits

Git identity rule

Rule

Every commit from this machine uses the chirag127 GitHub noreply email:

user.name  = Chirag Singhal
user.email = [email protected]

Set this at:

1. Global config: git config --global user.email "..." — covers any new clone.
2. Per-repo config in the umbrella: git config user.email "..." — overrides any inheritance from .gitconfig stashes.
3. Every submodule’s .git/config: the [user] section, if it exists, must match. Sweep with find .git/modules -name config -type f after any new submodule is added.

Why noreply, not [email protected] or [email protected]

• Zero public-email exposure. The noreply email is GitHub-issued and useless for spam-scraping.
• GitHub-guaranteed attribution. The numeric prefix 76880977+chirag127 is permanently bound to your user ID on GitHub — even if you rename the account, attribution survives.
• No verification step. [email protected] / [email protected] require adding to chirag127’s verified emails list and confirming via email — extra step that can drift if email auth lapses.

Windows Credential Manager hygiene

The “Select an account” popup appears when Windows Credential Manager has MULTIPLE GitHub credentials stored (e.g. oriz-co, chirag127, x-access-token, chirag127). Keep ONLY chirag127. Delete the rest with cmdkey /delete:<target> or via the Credential Manager GUI.

Past commits stay

DO NOT rewrite [email protected] commits to the noreply email retroactively. The rewrite:

• Breaks every fork rebase target (all 78+ submodules)
• Forces every clone to be re-cloned from scratch
• Triggers diff-noise across all 6 mirror hosts on next mirror cron
• Costs hours of mechanical work for cosmetic gain

The .git history is append-only. Going forward = clean. Past = preserved as-is.

Verification

After any new submodule or after this machine is set up fresh:

# Should print the noreply email at every level
git config --global user.email
git config user.email   # in the umbrella
git submodule foreach 'git config user.email || git config --global user.email'

# And the credential manager should only show chirag127
cmdkey /list | findstr github
