From 50a72e7a83a16d183a264e969a73cdbc7fb808f4 Mon Sep 17 00:00:00 2001 From: wxiaoguang Date: Wed, 12 Apr 2023 18:16:45 +0800 Subject: Use a general approach to access custom/static/builtin assets (#24022) The idea is to use a Layered Asset File-system (modules/assetfs/layered.go) For example: when there are 2 layers: "custom", "builtin", when access to asset "my/page.tmpl", the Layered Asset File-system will first try to use "custom" assets, if not found, then use "builtin" assets. This approach will hugely simplify a lot of code, make them testable. Other changes: * Simplify the AssetsHandlerFunc code * Simplify the `gitea embedded` sub-command code --------- Co-authored-by: Jason Song Co-authored-by: Lunny Xiao --- cmd/embedded.go | 122 ++++++++--------- cmd/embedded_stub.go | 29 ----- modules/assetfs/layered.go | 260 +++++++++++++++++++++++++++++++++++++ modules/assetfs/layered_test.go | 109 ++++++++++++++++ modules/auth/pam/pam_stub.go | 6 +- modules/context/context.go | 12 +- modules/doctor/paths.go | 3 +- modules/options/base.go | 118 ++--------------- modules/options/dynamic.go | 25 +--- modules/options/options.go | 45 ------- modules/options/static.go | 95 +------------- modules/public/public.go | 92 +++++++------ modules/public/serve_dynamic.go | 15 +-- modules/public/serve_static.go | 66 +--------- modules/repository/init.go | 2 +- modules/setting/asset_dynamic.go | 8 ++ modules/setting/asset_static.go | 8 ++ modules/svg/discover_bindata.go | 30 ----- modules/svg/discover_nobindata.go | 29 ----- modules/svg/svg.go | 29 ++++- modules/templates/base.go | 93 +++---------- modules/templates/dynamic.go | 72 +--------- modules/templates/htmlrenderer.go | 62 +++------ modules/templates/mailer.go | 63 ++------- modules/templates/static.go | 103 +-------------- modules/translation/translation.go | 14 +- modules/util/path.go | 19 ++- modules/util/path_test.go | 2 +- modules/util/timer.go | 28 ++++ modules/util/timer_test.go | 30 +++++ modules/watcher/watcher.go | 114 ---------------- routers/init.go | 9 +- routers/install/routes.go | 6 +- routers/install/setting.go | 3 +- routers/web/devtest/devtest.go | 15 ++- routers/web/web.go | 6 +- 36 files changed, 688 insertions(+), 1054 deletions(-) delete mode 100644 cmd/embedded_stub.go create mode 100644 modules/assetfs/layered.go create mode 100644 modules/assetfs/layered_test.go delete mode 100644 modules/options/options.go create mode 100644 modules/setting/asset_dynamic.go create mode 100644 modules/setting/asset_static.go delete mode 100644 modules/svg/discover_bindata.go delete mode 100644 modules/svg/discover_nobindata.go create mode 100644 modules/util/timer_test.go delete mode 100644 modules/watcher/watcher.go diff --git a/cmd/embedded.go b/cmd/embedded.go index d87fc0187c..cee8928ce0 100644 --- a/cmd/embedded.go +++ b/cmd/embedded.go @@ -1,8 +1,6 @@ // Copyright 2020 The Gitea Authors.
