From 7a13a9d545dda6122d87fab77da585b5b06de59d Mon Sep 17 00:00:00 2001 From: Piyush Shah Date: Fri, 16 Oct 2020 21:52:31 +0530 Subject: [PATCH] json: Use upstream json_generator and json_parser as submodules The JSON generator and JSON parser being used in ESP RainMaker were taken from third party repos. In order to ensure that they are better in sync with the upstream repos, they have now been included as submodules. Please run `git submodule update --init --recursive` once to pull in these submodules. --- .gitlab-ci.yml | 1 + .gitmodules | 6 + CHANGES.md | 5 + README.md | 20 +- components/json_generator/CMakeLists.txt | 8 +- components/json_generator/LICENSE | 176 ------- components/json_generator/component.mk | 5 +- components/json_generator/json_generator.c | 294 ----------- components/json_generator/json_generator.h | 485 ------------------ components/json_generator/upstream | 1 + components/json_parser/CMakeLists.txt | 8 +- components/json_parser/LICENSE | 176 ------- components/json_parser/component.mk | 4 +- .../json_parser/jsmn/include/jsmn-changed.h | 110 ---- .../json_parser/jsmn/src/jsmn-changed.c | 341 ------------ components/json_parser/json_parser.c | 382 -------------- components/json_parser/json_parser.h | 61 --- components/json_parser/upstream | 1 + 18 files changed, 39 insertions(+), 2045 deletions(-) create mode 100644 .gitmodules delete mode 100644 components/json_generator/LICENSE delete mode 100755 components/json_generator/json_generator.c delete mode 100755 components/json_generator/json_generator.h create mode 160000 components/json_generator/upstream delete mode 100644 components/json_parser/LICENSE delete mode 100644 components/json_parser/jsmn/include/jsmn-changed.h delete mode 100644 components/json_parser/jsmn/src/jsmn-changed.c delete mode 100755 components/json_parser/json_parser.c delete mode 100755 components/json_parser/json_parser.h create mode 160000 components/json_parser/upstream diff --git a/.gitlab-ci.yml b/.gitlab-ci.yml index 0d3c30d..5f592b3 100644 --- a/.gitlab-ci.yml +++ b/.gitlab-ci.yml @@ -7,6 +7,7 @@ variables: MAKEFLAGS: "-j8 --no-keep-going" IDF_PATH: "$CI_PROJECT_DIR/esp-idf" APP_BUILD: "all" + GIT_SUBMODULE_STRATEGY: recursive before_script: # add gitlab ssh key diff --git a/.gitmodules b/.gitmodules new file mode 100644 index 0000000..a0f013a --- /dev/null +++ b/.gitmodules @@ -0,0 +1,6 @@ +[submodule "components/json_parser/upstream"] + path = components/json_parser/upstream + url = https://github.com/espressif/json_parser.git +[submodule "components/json_generator/upstream"] + path = components/json_generator/upstream + url = https://github.com/espressif/json_generator.git diff --git a/CHANGES.md b/CHANGES.md index 867a4c6..4d670e7 100644 --- a/CHANGES.md +++ b/CHANGES.md @@ -1,5 +1,10 @@ # Changes +## 16-Oct-2020 (json: Use upstream json_generator and json_parser as submodules) + +To get these submodules, you will now have to execute `git submodule update --init --recursive` once. + +For new clones, use `git clone --recursive https://github.com/espressif/esp-rainmaker.git` ## 16-Oct-2020 (app_wifi: Changes in SSID and PoP generation for Provisioning) The PoP for Wi-Fi provisioning was being fetched from a random 8 character hex string stored in the fctry partition. diff --git a/README.md b/README.md index a283506..f5f5a93 100644 --- a/README.md +++ b/README.md @@ -18,6 +18,20 @@ The key features of ESP RainMaker are: 2.
