[PATCH v3 11/22] perf: add performance test for pickaxe

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add a test for the -G and -S pickaxe options and related options.

This test supports being run with GIT_TEST_LONG=1 to adjust the limit
on the number of commits from 1k to 10k. The 1k limit seems to hit a
good spot on git.git
