When updating references via git-fetch(1), then by default we report to the user which references have been changed. This output is formatted in a nice table such that the different columns are aligned. Because the first column contains abbreviated object IDs we thus need to iterate over all refs which have changed and compute the minimum length for their respective abbreviated hashes. While this effort makes sense in most cases, it is wasteful when the user passes the `--quiet` flag: we don't print the summary, but still compute the length. Skip computing the summary width when the user asked for us to be quiet. This gives us a small speedup of nearly 10% when doing a dry-run mirror-fetch in a repository with thousands of references being updated: Benchmark 1: git fetch --prune --dry-run +refs/*:refs/* (HEAD~) Time (mean ± σ): 34.048 s ± 0.233 s [User: 30.739 s, System: 4.640 s] Range (min … max): 33.785 s … 34.296 s 5 runs Benchmark 2: git fetch --prune --dry-run +refs/*:refs/* (HEAD) Time (mean ± σ): 30.768 s ± 0.287 s [User: 27.534 s, System: 4.565 s] Range (min … max): 30.432 s … 31.181 s 5 runs Summary 'git fetch --prune --dry-run +refs/*:refs/* (HEAD)' ran 1.11 ± 0.01 times faster than 'git fetch --prune --dry-run +refs/*:refs/* (HEAD~)' Signed-off-by: Patrick Steinhardt <ps@pks.im> --- builtin/fetch.c | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-)
