The CAR times out on both 0.26 and current PR in some tests, such as Double hash (blake3) Path block under blake3 root CID. This is because we don't have the data locally, and it seems that the node tries to fetch it.
This test returns 500 for the Libp2p gateway since it is an offline gateway.

It feels like some tests fail due to the same bug as #10361

Fail on both 0.26 and master.

@lidel I don't think any behaviour is different since 0.26. Could you double check? |

I also was not able to find a case which looks like a regression since 0.26.
Bit late on my end, but iiuc the bug described in #10361 was always present.
I propose we:
- proceed with Release 0.27 #10306 (RC2)
- close this PR draft – it served its purpose (comparing with 0.26 to identify regressions)
- merge cleanup from test: cleanup content blocking tests #10360 instead
- fix denylist:
?format=cardoes not skip directly blocked CIDs #10361 in next iteration (Kubo 0.28)

nit: does not matter much but this is a dir, not a file, so body will never match :-)

💭 During review, I've realized some things changed in refactors and dir names are confusing: blocked-dir is not blocked 🙃 and subdir is directly blocked, I fixed names in #10360 so its easier to reason about test file in the future.

💭 iiuc this does not pass because /ipfs/parentDirCID/subdir here is blocked by a subpath rule, and not by a CID rule (blockedCIDInParentDirCID). It was this way since the beginning, so not a regression blocking 0.27, but a bug which we should fix in future release.
I've added a version of this test that uses path and commented out one which does not pass yet to #10360
