From 4b3d38d5e15b0fd02839d5687b634e7999e12666 Mon Sep 17 00:00:00 2001 From: Gusted Date: Sat, 21 Oct 2023 13:30:19 +0200 Subject: [PATCH] [DEADCODE] Add deadcode linter - Add the experimental [deacode](https://pkg.go.dev/golang.org/x/tools/internal/cmd/deadcode) linter to Forgejo. - To deal with false positives that can happen due to build tags or with code that's currently only referenced by test code, the output of the tool is compared against a known-good output. - This commit doesn't make any attempt to remove any deadcode. (cherry picked from commit ac462279e9361070326d512fc209b6f148f27865) (cherry picked from commit b5ea6e85acecb8c02d18d51ec489bb1d329a33ce) (cherry picked from commit 5915f3643c1939ab09dcac8f9fcb74bd4231a16d) [CLEANUP] Remove deadcode - This is deadcode since https://codeberg.org/forgejo/forgejo/pulls/1802 removed the usage of it. (cherry picked from commit d840b9923e1a7aad7306c6b4d02df771ed0f40f4) (cherry picked from commit 9442bab6266807141a14a647d3bc383233fc56e9) (cherry picked from commit 0de9d18863c6af44941c7021548cdb07173ba3c0) (cherry picked from commit 26abf783746ef29e66eea966160e2f9c139add26) (cherry picked from commit 05d3a143c3785f3cc5e7f561aa2ad2ba556b55cc) --- .deadcode-out |
