Description
For example:
$ arv keep put mirobot_updater
Traceback (most recent call last):
File "/usr/local/bin/arv-put", line 4, in <module>
main()
File "/usr/local/lib/python2.7/dist-packages/arvados/commands/put.py", line 411, in main
bytes_expected = expected_bytes_for(args.paths)
File "/usr/local/lib/python2.7/dist-packages/arvados/commands/put.py", line 333, in expected_bytes_for
bytesum += os.path.getsize(os.path.join(path, filename))
File "/usr/lib/python2.7/genericpath.py", line 49, in getsize
return os.stat(filename).st_size
OSError: [Errno 2] No such file or directory: 'mirobot_updater/resources/app/node_modules/.bin/serialportlist'
and
$ ls mirobot_updater/resources/app/node_modules/.bin/serialportlist -laF lrwxrwxrwx 1 wardtest wardtest 35 Jan 10 19:41 mirobot_updater/resources/app/node_modules/.bin/serialportlist -> ../serialport/bin/serialportList.js
arv keep put should just skip things it can not save, and ideally list at the end of the run which file(s) it skipped.

It does this if you specify any kind of nonexistent file, not just a dangling symlink. I assume you want nicer error reporting? There's a lot of room for improvement in all the CLI tools there—exception tracebacks are still the way most problems are presented to users.

Yeah, I think the desired behavior would be that arv keep put skips any files it can not upload, and prints out the list of errors at the end. It shouldn't abort the upload because there's one dangling symlink in a directory tree.

- Do you want it to skip on any OS error when it tries to open the file?
- Do you want to adjust the behavior if there's an error while reading the file after opening?
- What should the exit code be in this case?
- Should there be different exit codes for the case of "couldn't upload some files" vs. "couldn't upload any files?"

Perhaps rsync's behavior in the face of IO errors is a good model to follow. "Some stuff failed along the way, so exiting non-zero. But I did everything I could."

Yeah. That's right.
