  • Facebook does not use Git due to scale issues with their large monorepo, instead opting for Mercurial.
  • Mercurial may be a better option for large monorepos, but Git has made improvements to support them better.
  • Despite some drawbacks, Git usage remains dominant with 93.87% share, due to familiarity, additional tools, and industry trends.

That's exactly the same in git. The old commits are still there, they just don't show up in git log because nothing points to them.

Old, unreachable commits will be garbage collected.

Does that not happen with Mercurial? If not that seems like a point against it.

[-] aport@programming.dev 1 points 3 months ago

I'm confused, the behavior you just said was "exactly the same in git" is now a problem for Mercurial?

[-] FizzyOrange@programming.dev 1 points 3 months ago

I thought it was exactly the same based on the description.

No the old commit is always there, marked as obsolete with the information of what it became. No holes in history. (Assuming you use the obsolecense markers)
