From ef11d41639dd1e89676e395068ee453312560adb Mon Sep 17 00:00:00 2001 From: zeripath Date: Mon, 20 Feb 2023 05:20:30 +0000 Subject: [PATCH] Make CI use a dummy password hasher for all tests (#22983) During the recent hash algorithm change it became clear that the choice of password hash algorithm plays a role in the time taken for CI to run. Therefore as attempt to improve CI we should consider using a dummy hashing algorithm instead of a real hashing algorithm. This PR creates a dummy algorithm which is then set as the default hashing algorithm during tests that use the fixtures. This hopefully will cause a reduction in the time it takes for CI to run. --------- Signed-off-by: Andrew Thornton Co-authored-by: Lunny Xiao --- models/fixtures/user.yml | 132 +++++++++++------------ models/unittest/fixtures.go | 10 ++ modules/auth/password/hash/argon2.go | 2 +- modules/auth/password/hash/bcrypt.go | 2 +- modules/auth/password/hash/dummy.go | 33 ++++++ modules/auth/password/hash/dummy_test.go | 25 +++++ modules/auth/password/hash/hash.go | 13 ++- modules/auth/password/hash/hash_test.go | 8 +- modules/auth/password/hash/pbkdf2.go | 2 +- modules/auth/password/hash/scrypt.go | 2 +- modules/setting/setting.go | 5 + 11 files changed, 160 insertions(+), 74 deletions(-) create mode 100644 modules/auth/password/hash/dummy.go create mode 100644 modules/auth/password/hash/dummy_test.go diff --git a/models/fixtures/user.yml b/models/fixtures/user.yml index b5f8b27215..b1c7fc0030 100644 --- a/models/fixtures/user.yml +++ b/models/fixtures/user.yml @@ -8,8 +8,8 @@ email: user1@example.com keep_email_private: false email_notifications_preference: enabled -
