See the [Plugins Upgrade Guide – Upgrading to the new KeyMetastore Plugin](plugins-upgrade-guide.md#upgrading-to-the-new-keymetastore-plugin). +- **Dispose:** Both the session and the session factory should be disposed when no longer needed; prefer `using` for sessions. diff --git a/tartufo.toml b/tartufo.toml index 029f2ab05..2dc0fe3ca 100644 --- a/tartufo.toml +++ b/tartufo.toml @@ -56,6 +56,11 @@ exclude-signatures = [ { signature = "cf90106ca7fcc09ff9d8f07a2ea8f9f02a0758f26031808d1cc1f4d38c712f58", reason = "High entropy findings (dummy encryoted payloads, fake keys, method names, etc.) in C# tests"}, { signature = "5923f959a8738aacb46e92db00f78d64eaa0121fe33edbf3571d676f1355d08c", reason = "High entropy findings (dummy encryoted payloads, fake keys, method names, etc.) in C# tests"}, { signature = "4244fda6859ee07323c9787a7fd65a7afb3f001019ca5a362b77a0a1fb63ccda", reason = "High entropy findings (dummy encryoted payloads, fake keys, method names, etc.) in C# tests"}, + { signature = "d443501bf2d6eaa001dbe362f23e5d547b460f878b0455aaed36549c4fc8a415", reason = "High entropy findings (dummy encryoted payloads, fake keys, method names, etc.) in C# tests"}, + { signature = "086e498d8eda0c6de875f45ce13fb715f468d1d6c56e2e0f13dba0c9d9ae13b6", reason = "High entropy findings (dummy encryoted payloads, fake keys, method names, etc.) in C# tests"}, + { signature = "3896f078bd2434d7d70a38934e314f25215f90be0dbb745b6d9a7156231cf601", reason = "High entropy findings (dummy encryoted payloads, fake keys, method names, etc.) in C# tests"}, + { signature = "dc0fb2464d4d00d122106036f31e628ceedfa5231e0aab2942c5cfea33db9848", reason = "High entropy findings (dummy payloads, fake keys, etc.) in C# MetastoreCompatibilityTest"}, + { signature = "ef125e46e699f84efac57caea87446602d1d05b6703815afd9d2781a6e69113d", reason = "High entropy findings (dummy payloads, fake keys, etc.) in C# MetastoreCompatibilityTest"}, { signature = "0d4a2e3037d931239373f7f547542616cc64fc583072029e6b3a2e77e8b7f89e", reason = "High entropy findings (dummy encryoted payloads, fake keys, method names, etc.) in Go Tests"}, { signature = "3b43730726f7dd09bb41870ddb5b65e77b6b2b8aab52f40e9237e6d2423cfcb3", reason = "High entropy findings (dummy encryoted payloads, fake keys, method names, etc.) in Go Tests"}, @@ -83,6 +88,7 @@ exclude-signatures = [ ] exclude-path-patterns = [ + {path-pattern = '.*/Regression/Metastore/MetastoreCompatibilityTest\.cs', reason = 'C# integration test: dummy payloads, static KMS key reference'}, {path-pattern = '.*/(L|LL)P64/.*', reason = 'Exclude LP64 paths'}, {path-pattern = '.*\.DotSettings', reason = 'Exclude DotSettings files'}, {path-pattern = '.*/go.mod', reason = 'Exclude go.mod files'},
