Mac OS 10.5 shell 使用defaults rea

Mac OS 10.5 shell 使用defaults read读取文件显示does not exist

Mac os 升级到10.15后打包tweak项目失败，原因在于执行iosod这个sh时出错，以下方法为根据key读取plist中value：

function readDefaultsValue() # args: plistPath, propertyName
{
    $setCmd
    
    local plistPath="$1"
    local propertyName="$2"
    local value
    
    value=`defaults read "${plistPath%.*}" "$propertyName"` || \
        panic $? "Failed to read defaults property $propertyName from $plistPath"

    # return #
    echo "$value"
}

function getVersionFromVersionPList() # args: plistPath
{
    $setCmd
    
    local plistPath="$1"
    local version
    local major
    local minor
    local bugFix
    local stage
    local pkgRev
    
    major=`readDefaultsValue "$plistPath" "Major"`
    minor=`readDefaultsValue "$plistPath" "Minor"`
    bugFix=`readDefaultsValue "$plistPath" "BugFix"`
    stage=`readDefaultsValue "$plistPath" "Stage"`
    pkgRev=`readDefaultsValue "$plistPath" "PackageRevision"`

    version="$major.$minor"
        
    [[ "$bugFix" == "" ]] || version+=".$bugFix"
    [[ "$stage" == "" ]] || version+="$stage"
    [[ "$pkgRev" == "" ]] || version+="-$pkgRev"
        
    # return #
    echo "$version"
}

上面的方法作用在于读取PackageVersion.plist中的key和value，等同于，在终端中读取plist文件

swae@swaedeMacBook-Pro ~ % defaults read /Users/swae/Desktop/work/Tweak/tweakpro/tsprite/tsprite/PackageVersion.plist  Major
2019-10-14 23:04:42.792 defaults[7909:308363]
The domain/default pair of (/Users/swae/Desktop/work/Tweak/tweakpro/tsprite/tsprite/PackageVersion.plist, Major) does not exist

从上面的输出可以看出，读取这个plist文件不存在，而经过我的验证使用defaults read读取大部分的plist文件都显示does not exist，但是当我使用defaults write 时，却显示exiting无法写入，尴尬，下面为输入：

swae@swaedeMacBook-Pro ~ % defaults write /Users/swae/Desktop/work/Tweak/tweakpro/tsprite/tsprite/PackageVersion.plist  Major1 200
2019-10-14 23:08:47.076 defaults[7976:310697] Could not write domain /Users/swae/Desktop/work/Tweak/tweakpro/tsprite/tsprite/PackageVersion.plist; exiting

无奈中，我尝试使用defaults write 写入一个新的plist文件，然后再使用defaults read读取却是正常的：

swae@swaedeMacBook-Pro ~ % defaults write /Users/swae/Desktop/work/Tweak/tweakpro/tsprite/tsprite/PackageVersion1.plist method 1000
swae@swaedeMacBook-Pro ~ % defaults read /Users/swae/Desktop/work/Tweak/tweakpro/tsprite/tsprite/PackageVersion1.plist method
1000

以上是我在Mac os 10.15上实际操作得到的结果，我把锅甩给了新系统，但是当我在Mac os 10.14.6的终端上操作时，依旧是以上结果，目前还不清楚原因，待近一步排查。

下面两张图为了说明这两个plist的不同

通过defaluts_write创建的plist，可以通过defaults read 读取key。

最终我使用新建的PackageVersion1 .plist替换调旧的，重新执行build for->profiling，问题暂时解决：

感谢简友[Ninja400]提供的方法：
将default read CFBundleVersion 更换为 `/usr/libexec/PlistBuddy -c "Print CFBundleVersion" $SRCROOT/tweek/Info.plist``

替换/opt/iOSOpenDev/bin/iosod中的readDefaultsValue方法

function readDefaultsValue() # args: plistPath, propertyName
{
    $setCmd
    
    local plistPath="$1"
    local propertyName="$2"
    local value

    value=`/usr/libexec/PlistBuddy -c "Print '$propertyName'" "$plistPath"` || \
        panic $? "Failed to read defaults property $propertyName from $plistPath"
      # 使用defaults read无法读取plist
    # value=`defaults read "${plistPath%.*}" "$propertyName"` || \
        # panic $? "Failed to read defaults property $propertyName from $plistPath"

    # return #
    echo "$value"
}

但是最终还是报错setControlFileVersionFieldUsingVersionPList

暂时这样修改setControlFileVersionFieldUsingVersionPList

function setControlFileVersionFieldUsingVersionPList() # args: controlFile, plistPath
{
    local controlFile="$1"
    local plistPath="$2"
    local versionReadFromPList
    
    requireFile "$controlFile" false
    requireFile "$plistPath" false
    
    # read plist to get version #
    echo "read plist to get version..."
    versionReadFromPList=`getVersionFromVersionPList "$plistPath"`
    
    [[ $versionReadFromPList != "" ]] || \
        panic 1 "Failed to read version from $plistPath"

    # write version to control file #

    echo -n "Setting control file $controlFile Version field to $versionReadFromPList using $plistPath... "

    # sed -i "" "s/Version:.*/Version: $versionReadFromPList/g" "$controlFile" || \
        # panic $? "Failed."

    # success #
    echo "Done."
}
