[SDKs] There is no way to silence arv-put and arv-get
Added by Abram Connelly about 9 years ago.
Updated almost 7 years ago.
Description
On successful upload, 'arv-put' spits out a message of the form "Collection saved ...". There is no way to silence this output short of redirecting stderr to /dev/null. 'arv-put' and 'arv-get' should at least have an option to silence non-error stderr messages.
This came up in the context of trying to automate 'arv-put' upload through a cron job. Since 'arv-put' sends a message on successful upload to keep, the only way to silence spurious email reporting is to redirect stderr to /dev/null, precluding the possibility of catching real errors.

Test run: https://ci.curoverse.com/job/developer-run-tests/382/ (not sure if they're working now)
Added --silent flag to arv-put so that it doesn't produce any output on normal operations.
Added related tests.
For the arv-get command, I believe that passing the already existing --no-progress flag would produce the desired outcome.
- "Do not produce any output unless an error happens." => "Do not print any debug messages to console. (Any error messages will still be displayed.)" ?
- test_no_progress_when_stderr_not_a_tty
Can you please throw in a new line between the two test blocks (is tty and not tty)? Also, moving the comment “Confirm that progress is written to stderr when is a tty” and its counterpart to before setting the tty flag might improve readability of each of the code blocks
- test_silent_mode => test_silent_mode_no_errors? Also, you might want to consider saying "no console output will be printed" instead of "no output will be printed" in the comments in the tests.
Thanks.
- Status changed from In Progress to Resolved
