we are trying to script a fail-safe copy using gsutil.

The problem is that gsutil cp returns 0 even if it failed. Is this expected? Do i have to parse the log?

/usr/local/bin/gsutil -m cp -L gsutilM.log gs://my-bucket/mydir/myfile1.gz /home/myuser

From log file:

Result,Description
error, CommandException: crc32c signature computed for local file (FGa0jw==) doesn't match     cloud-supplied digest (N1S6Ew==).
Local file (/home/myuser/myFile1.gz) will be deleted.

Thanks

  • It is not a gsutil problem. My startup-script was using a wrong parameter and was not handling the return code properly. sorry, my mistake.

I tried modifying the code that makes the crc32c check, to force that condition to occur. I then downloaded a file, saw output like you saw, and verified that $status was set to 1.

What OS and shell are you using?

  • Also, which version of gsutil are you using? If you're not using the latest version, please try updating - I believe we've already fixed this problem, but it's possible this is a different manifestation.

  • Hi - I found this article that tells you how to check the command exit status after calling Perl's system() function: perlhowto.com/executing_external_commands
