From 21020430a4a08d2e31c1c6825e53f194569c706c Mon Sep 17 00:00:00 2001 From: Patrick Steinhardt Date: Fri, 13 Nov 2020 09:12:41 +0100 Subject: p1400: use `git-update-ref --stdin` to test multiple transactions In commit 0a0fbbe3ff (refs: remove lookup cache for reference-transaction hook, 2020-08-25), a new benchmark was added to p1400 which has the intention to exercise creation of multiple transactions in a single process. As git-update-ref wasn't yet able to create multiple transactions with a single run we instead used git-push. As its non-atomic version creates a transaction per reference update, this was the best approximation we could make at that point in time. Now that `git-update-ref --stdin` supports creation of multiple transactions, let's convert the benchmark to use that instead. It has less overhead and it's also a lot clearer what the actual intention is.
