工作之解讀py腳本

下面問題的描述不重要，想必每個(gè)公司都有它自己的一套客制化需求，主要是思路。
今天遇到個(gè)問題，就是訂單的版本號對應(yīng)不對，平常高通訂單版本號都是在config.mk文件改寫，找了很久沒有頭緒。后面直接在vendor（客制化，公司訂單客制化需求在這下面）下搜索文件錯誤的訂單版本號，搜索bash命令如下

 grep -rni --include="*" --exclude-dir=out "錯誤訂單版本號" ./

搜索到configwikoinfo.ini文件原來公司為Wiko的Unify，這個(gè)坑新接MR版本的我哪知道。原來fingerprint也是在這里面定義的（平常在buildinfo.sh文件里面），fingerprint固定的，我靠，MR與上一送測版本fingerprint一致，google是不會接受的直接打回來，差點(diǎn)背鍋。
configwikoinfo.ini

#內(nèi)部、外部版本號，產(chǎn)品名稱、品牌等等，fingerprint
TCUSTOM_BUILD_VERNO_FR = ...
CUSTOM_BUILD_VERNO_FR = ...
INTERNAL_BUILD_VERNO_FR = ...
WIK_PRODUCT_MODEL_FR = ...
WIK_PRODUCT_NAME_FR = ...
WIK_PRODUCT_DEVICE_FR = ...
WIK_PRODUCT_BOARD_FR = ...
#fixed BUILD_FINGERPRINT build number line
WIK_BUILD_FINGERPRINT_FR =  ...

然而這個(gè)文件又有什么用了，原來在另一個(gè)倉庫下有一個(gè)bwc.mk文件

# check configwikoinfo.ini path
ifeq ($(strip $(SUB_PROJECT_NAME)),)
wik_config_path := vendor/tinno/${TARGET_PRODUCT}/${PROJECT_NAME}/unify/configwikoinfo.ini
else
wik_config_path := vendor/tinno/${TARGET_PRODUCT}/${PROJECT_NAME}/SUB_PROJECTS/${SUB_PROJECT_NAME}/unify/configwikoinfo.ini
endif

$(warning "wik_config_path = $(wik_config_path)")
result := $(shell ./vendor/tinno/requirement/wik_common/unify/tools/BWC/buildwiko.py "${wik_config_path}" "WIKO" "$(PLATFORM_VERSION)" "$(BUILD_ID)" "$(TARGET_BUILD_VARIANT)" "release-keys")
$(warning "-- build wiko area --")

由上bwc.mk文件可知得到configwikoinfo.ini文件路徑，然后運(yùn)行buildwiko.py腳本，傳入全局參數(shù)

前幾天剛學(xué)過一點(diǎn)python，發(fā)揮一點(diǎn)余熱然后自行分析該腳本邏輯。腳本比較簡單易懂
1.先拿出參數(shù)賦值到變量中
2.然后通過傳進(jìn)來參數(shù)路徑解讀configwikoinfo.ini文件
3.然后就是判斷邏輯操作，組建字符串寫入相應(yīng)的文件中了。寫入文件的輸出路徑顯而易見，在本同腳本目錄下

解讀完腳本之后就會修改了，從邏輯上看，只要wik_build_fingerprint等于null，它就會根據(jù)產(chǎn)品信息和時(shí)間戳等信息生成fingerprint數(shù)值。前面已經(jīng)提到了我的需求，不與上一版本的fingerprint一樣。直接將onfigwikoinfo.ini的WIK_BUILD_FINGERPRINT_FR值注釋，這樣就解決了。之后還需要同意fingerprint。要求BUILD_NUMBER里面不包含android這個(gè)字符串，這也很簡單注釋掉BUILD_NUMBER = "android" + BUILD_NUMBER這條語句
bwc.mk除上面以外的還做了意見事情

PRODUCT_COPY_FILES += $(LOCAL_PATH)/unify/tools/BWC/du:system/vendor/wiko/du
PRODUCT_COPY_FILES += $(LOCAL_PATH)/unify/tools/BWC/fr:system/vendor/wiko/fr
PRODUCT_COPY_FILES += $(LOCAL_PATH)/unify/tools/BWC/id:system/vendor/wiko/id
PRODUCT_COPY_FILES += $(LOCAL_PATH)/unify/tools/BWC/my:system/vendor/wiko/my
PRODUCT_COPY_FILES += $(LOCAL_PATH)/unify/tools/BWC/th:system/vendor/wiko/th
PRODUCT_COPY_FILES += $(LOCAL_PATH)/unify/tools/BWC/vn:system/vendor/wiko/vn

把腳本生成的信息文件copy到Android手機(jī)system/vendor/wiko 目錄下，以備手機(jī)讀取其中的信息。

真正意義上了解了Python的用處與強(qiáng)大。

打完P(guān)atch跑GMS出現(xiàn)錯誤，Google對于GMS認(rèn)證要求是不斷更新，毫無疑問，項(xiàng)目越久要求越多
果然，跑玩一輪GMS準(zhǔn)備修改fail，又下面這種情況

Hi SPMs & TLs
根據(jù)谷歌最新的BTS（谷歌從6月份才強(qiáng)制check BTS測試）測試通知，要求fingerprint里的時(shí)間戳版本號要和ro.build.version.incremental的值保持一致，我們當(dāng)前很多項(xiàng)目因?yàn)椴灰恢聦?dǎo)致送測3PL被拒，各位請及時(shí)安排工程師進(jìn)行check和修改

*理解了這種模式其實(shí)修改起來十分簡單，首先查看buildinfo.sh文件 echo "ro.build.version.incremental=$BUILD_NUMBER" 由此可知，ro.build.version.incremental這個(gè)值是等于BUILD_NUMBER宏，具體值eng.android.{時(shí)間戳}，具體構(gòu)造在build倉庫腳本下，懶得看了。
*由上面那個(gè)buildwiko.py腳本可知，BUILD_NUMBER這個(gè)值不是取的Android項(xiàng)目整個(gè)宏，而是自己在腳本中構(gòu)造的，部分代碼如下：

(status, BUILD_NUMBER) = commands.getstatusoutput('date +%s -d  \'+121 min\'')

剛開始這就讓我十分頭疼了，腳本代碼生成的時(shí)間戳，毫無疑問不滿足Google最新BTS測試通知，如何修改就從這個(gè)腳本入手了，首先如何取得這個(gè)宏，如何去得到呢？對這方面毫無經(jīng)驗(yàn)
不過看到bwc.mk文件中

result := $(shell ./vendor/tinno/requirement/wik_common/unify/tools/BWC/buildwiko.py "${wik_config_path}" "WIKO" "$(PLATFORM_VERSION)" "$(BUILD_ID)" "$(TARGET_BUILD_VARIANT)" "release-keys"）

這段，我猜想$(PLATFORM_VERSION)這種就是取得Android項(xiàng)目中的宏，然后當(dāng)做腳本參數(shù)傳入其中，抱著這種猜想，試試。

result := $(shell ./vendor/tinno/requirement/wik_common/unify/tools/BWC/buildwiko.py "${wik_config_path}" "WIKO" "$(PLATFORM_VERSION)" "$(BUILD_ID)" "$(TARGET_BUILD_VARIANT)" "release-keys" "$(BUILD_NUMBER)")

就改成這樣，然后依葫蘆畫瓢，在buildwiko.py中接收參數(shù) BUILD_NUMBER = sys.argv[7] ，然后對這個(gè)自行改造 BUILD_NUMBER = BUILD_NUMBER[12:]，只截取時(shí)間戳的部分。既然BUILD_NUMBER是作為參數(shù)傳入，就不需要自己在腳本中構(gòu)造。build_wiko_config(config_file_path):函數(shù)中關(guān)于BUILD_NUMBER構(gòu)造全部都刪了。
