googlecloudlogging's Issues

Some of these errors could be resolved simply by changing import Foundation to:

import Foundation
#if canImport(FoundationNetworking)
    import FoundationNetworking
#endif

It looks like the authentication portions of it would need to be replaced by either CryptoSwift or google-auth-library-swift, both of which support Linux. The latter is Google's official library for authenticating with Google Cloud and may readily replace this functionality.

Log size handling

The log size handling is wrong .. it is based on the number of lines before being encoded.

I see some logs not being uploaded and a log of errors like:

error=errorReceived(GoogleCloudLogging.GoogleCloudLogging.Response.Error(code: 400, message: "Request payload size exceeds the limit: 10485760 bytes.", status: "INVALID_ARGUMENT")) [GoogleCloudLogging] Unable to upload 
excludedLogEntryCount=4 maxLogSize=10000000 [GoogleCloudLogging] Some log entries are excluded from the upload due to exceeding the log size limit

How to change Label in logs?

This is a typical out of the box log from the library:

2021-06-12T12:03:48-0400 info GoogleCloudLogHandler : Logs have been uploaded

How do i change the label "GoogleCloudLogHandler" so that it does not show in the Google Cloud Logging console,
it reflects something another label?

Thanks for the library!

How do I upload logs immediately?

In your introduction you state that logs can be uploaded in response to a given event. How do we customise this? As I am developing the app, I would like immediate upload to the backend. Currently I have the following, which works, but this obviously then removes the usefulness of the source error information that is uploaded and I suspect isn't the proper way to do it.

class CustomLogging {
    static var shared = CustomLogging()
    
    public func info(message: String) {
        logger.info("\(message)")
        GoogleCloudLogHandler.upload()        
    }
}

let Log = CustomLogging.shared

//somewhere else
Log.info(message:"whatever")
