Fingerprint validation fails when artifacts have different filenames but same contents/hash

[gjb1002]

ISSUE TYPE

• Bug Report

Jenkinsapi 0.3.9

Jenkins 2.150.2

SUMMARY

If I do "Replay" from a pipeline build it confuses the fingerprint handling code, frequently leading to errors when the fingerprints are perfectly correct. This seems to be because the new artifact has the same content and hence md5sum but a different file name (our artifact has a timestamp in its name), leading to the "original" structure having the wrong data.

EXPECTED RESULTS

Fingerprints should match correctly.

ACTUAL RESULTS

jenkinsapi.custom_exceptions.ArtifactBroken: Artifact c95cdb45923926b28833833b770770e1 seems to be broken, check <jenkins url>

In log

Filename from jenkins (<artifact name from original build>) did not match provided (<artifact name from replayed build>)

[gjb1002]

A key question is what purpose the filename check that leads to this error in the "validate_for_build" method in fingerprint.py actually serves?

if self._data["fileName"] != filename:

What can actually lead to this error being emitted correctly, other than internal errors in Jenkins?

The same problem, and still not work for save

artifact.save(fspath(path), False)

What is the use case in your code?

Fingerprints are found by MD5 and first file that has this fingerprint will be referred via "fileName" attribute and this is current check. At the same time, the list of all files with the same fingerprint is returned. This is not currently checked. Do you want check to be made that your file is in that list?

[gjb1002]

I want it to work :) The only thing I have that is at all unusual is that several files have different names but the same MD5. This leads to the error above if I enable fingerprints and try to save artifacts via jenkinsapi.

I don't really see the point of the check, so I would be happy for it to be removed, but keeping track of all the files with a certain MD5 and checking that the file is in the list would also work I guess.

@gjb1002 I too have experienced this issue where I have one original file and another with a timestamp appended too it. I don't see the importance of checking the file name during the verification process in fingerprint, but if it is to remain I think checking all file names that have a matching MD5 and return true on a single match instance would be a reasonable fix.

This was reported as issue #430. I came across this failure as well. I find that verifying the filename is useless due to the way Jenkins allows multiple artifacts to be identical yet have different names. I have submitted PR-851.
