Handling for missing HashFormatType #114

Open jmccdev opened 2 years ago

jmccdev commented 2 years ago

I created an ASC MHL History using the command line tool:

$ ascmhl create -h md5 <directory>

Afterwards, I manually removed action="original" from each hash register:

$ grep md5 16421225_Day001/ascmhl/0001_16421225_Day001_2022-02-08_224657.mhl 
      <md5 hashdate="2022-02-08T14:46:57.021683-08:00">9290a2ca3f586cb53da7cb516610fed2</md5>
      <md5 hashdate="2022-02-08T14:46:57.082991-08:00">4a4d102cb08af8ee4a96076ed5e51c43</md5>
      <md5 hashdate="2022-02-08T14:46:57.083792-08:00">a905ef013e401b93bd38b345ed9a7c33</md5>
      <md5 hashdate="2022-02-08T14:46:57.132443-08:00">67719b016da2dc1aaf4719da1219c756</md5>
      <md5 hashdate="2022-02-08T14:46:57.133264-08:00">2ef696b05bd9dbbef4e7c4e561b0d02f</md5>
      <md5 hashdate="2022-02-08T14:46:57.193704-08:00">dbbdf624486bce1232692628106bbe99</md5>
      <md5 hashdate="2022-02-08T14:46:57.194401-08:00">291ebdcdf07232e86b1e79fc7982abc2</md5>
      <md5 hashdate="2022-02-08T14:46:57.195028-08:00">c25b1cebea75d06b542d8208193ac97c</md5>

I then ran the create command on the same directory. There was no error about the missing HashFormatType, and the 0002* MHL that was created was given a HashFormatType of 'original' rather than 'verified':

$ grep action 16421225_Day001/ascmhl/0002_16421225_Day001_2022-02-15_005147.mhl
