From 88f9234e9aa1e3a81161c32d4e60beb96cdb2c20 Mon Sep 17 00:00:00 2001 From: RISCi_ATOM Date: Thu, 30 Sep 2021 17:11:38 -0400 Subject: [PATCH] luci: Remove jsmin from luci and use the jsmin Python module instead. The project is being forced to remove jsmin from luci due to it being under the infamous JSON license. This commit removes jsmin and, as a result, the jsmin Python module will need to be installed in order to build libreCMC / luci. --- include/prereq-build.mk | 4 + package/luci/luci.mk | 2 +- package/luci/modules/luci-base/Makefile | 3 +- package/luci/modules/luci-base/src/Makefile | 3 - package/luci/modules/luci-base/src/jsmin.c | 292 -------------------- 5 files changed, 6 insertions(+), 298 deletions(-) delete mode 100644 package/luci/modules/luci-base/src/jsmin.c diff --git a/include/prereq-build.mk b/include/prereq-build.mk index e3614f51ee..29960b148f 100644 --- a/include/prereq-build.mk +++ b/include/prereq-build.mk @@ -151,6 +151,10 @@ $(eval $(call SetupHostCommand,python,Please install Python >= 3.5, \ python3.5 -V 2>&1 | grep 'Python 3', \ python3 -V 2>&1 | grep -E 'Python 3\.[5-9]\.?')) +$(eval $(call TestHostCommand,python3-jsmin, \ + Please install the jsmin Python module, \ + python3 -c "import jsmin" 2>&1 )) + $(eval $(call SetupHostCommand,git,Please install Git (git-core) >= 1.7.12.2, \ git --exec-path | xargs -I % -- grep -q -- --recursive %/git-submodule)) diff --git a/package/luci/luci.mk b/package/luci/luci.mk index bb8ba8e5fd..ba09387db1 100644 --- a/package/luci/luci.mk +++ b/package/luci/luci.mk @@ -169,7 +169,7 @@ endef define JsMin $(FIND) $(1) -type f -name '*.js' | while read src; do \ - if jsmin < "$$$$src" > "$$$$src.o"; \ + if python3 -m jsmin "$$$$src" > "$$$$src.o"; \ then mv "$$$$src.o" "$$$$src"; fi; \ done endef diff --git a/package/luci/modules/luci-base/Makefile b/package/luci/modules/luci-base/Makefile index 9bc8ec17a1..06ee7985eb 100644 --- a/package/luci/modules/luci-base/Makefile +++ b/package/luci/modules/luci-base/Makefile @@ -36,14 +36,13 @@ define Host/Configure endef define Host/Compile - $(MAKE) -C src/ clean po2lmo jsmin + $(MAKE) -C src/ clean po2lmo endef define Host/Install $(INSTALL_DIR) $(1)/bin $(INSTALL_DIR) $(1)/lib/lua/5.1 $(INSTALL_BIN) src/po2lmo $(1)/bin/po2lmo - $(INSTALL_BIN) src/jsmin $(1)/bin/jsmin $(INSTALL_BIN) $(HOST_BUILD_DIR)/bin/luasrcdiet $(1)/bin/luasrcdiet $(CP) $(HOST_BUILD_DIR)/luasrcdiet $(1)/lib/lua/5.1/ endef diff --git a/package/luci/modules/luci-base/src/Makefile b/package/luci/modules/luci-base/src/Makefile index 3e6ead1085..03e887e1d5 100644 --- a/package/luci/modules/luci-base/src/Makefile +++ b/package/luci/modules/luci-base/src/Makefile @@ -4,9 +4,6 @@ clean: rm -f po2lmo parser.so version.lua *.o -jsmin: jsmin.o - $(CC) $(LDFLAGS) -o $@ $^ - po2lmo: po2lmo.o template_lmo.o $(CC) $(LDFLAGS) -o $@ $^ diff --git a/package/luci/modules/luci-base/src/jsmin.c b/package/luci/modules/luci-base/src/jsmin.c deleted file mode 100644 index d23718df39..0000000000 --- a/package/luci/modules/luci-base/src/jsmin.c +++ /dev/null @@ -1,292 +0,0 @@ -/* jsmin.c - 2011-09-30 - -Copyright (c) 2002 Douglas Crockford (www.crockford.com) - -Permission is hereby granted, free of charge, to any person obtaining a copy of -this software and associated documentation files (the "Software"), to deal in -the Software without restriction, including without limitation the rights to -use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies -of the Software, and to permit persons to whom the Software is furnished to do -so, subject to the following conditions: - -The above copyright notice and this permission notice shall be included in all -copies or substantial portions of the Software. - -The Software shall be used for Good, not Evil. - -THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR -IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, -FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
