react-native-blob-util [iOS] Memory usage not being clean after successful upload

[iOS] Memory usage not being clean after successful upload

Open kyoungnowcom opened this issue 3 years ago • 6 comments

Hi, when uploading a large amount of files using ReactNativeBlobUtil.fetch(), the memory usage will climb steadily and it will not get cleared up after each successful upload, even after the entire upload process gets completed with some wait time thereafter. And there were no other activities while conducting the test. See screenshot, sample code below. Any suggested changes to flush the memory or this is an expected behavior?

Any input will highly appreciated. Thank you!

Sample code snippet

const testUpload = async () => {
    const fileBasePath = RNBlobUtil.fs.dirs.DocumentDir.replace(
      /\/Documents$/,
      '/tmp/react-native-image-crop-picker/',
    );
    console.log('fileBasePath', fileBasePath);
    const imageFiles = await RNBlobUtil.fs.ls(fileBasePath);

    for (let i = 0; i < imageFiles.length; i++) {
      const filePath = fileBasePath + imageFiles[i];
      try {
        await RNBlobUtil.config({
          fileCache: false,
        }).fetch(
          'PUT',
          'https://<subdomain>.blob.core.windows.net/<params>',

          RNBlobUtil.wrap(
            Platform.OS === 'ios'
              ? filePath!.replace('file://', '')
              : filePath!,
          ),
        );
        console.log('uploaded ' + i + ',' + filePath);
      } catch (error) {
        console.error('error on ' + i, error);
      }
    }
  };
