Iterating through a database with firstkey() and nextkey() is guaranteed to retrieve all rows, but apparently not in any particular order. This is causing a test failure for at least one user, so we steal the sort() approach from GDBM to ensure that the output is predictable.
The actual output is now sorted for consistency, so we need to update the expected output as well. As a nice side effect, some differences in the expected outputs for the various engines have been eliminated. Closes phpGH-14786

Windows won't (only QDBM and LMDB are tested on CI, currently). I haven't checked other OSs. |
This test uses a routine from ext/dba that now sorts its (actual) output, so we have to sort the expected output here as well.

After doing some more digging, it looks like GDBM isn't the only engine where the iteration order with firstkey() and nextkey() might change unexpectedly.

Thanks, I added one more commit to clarify the comment. |

Alpine hit the sorting issue too: #16902 (comment) |
|
Yeah probably should |
|
OK. I'll get to it, I'll make a PR soon and if that passes CI merge it. |

Alpine CI regularly fails because of the sorting order of these tests. See php#14962 (comment)

Fixes #14786 by sorting the fetched rows before
echoing them, and updating the expected output to reflect the sort order.I don't have dbm, ndbm, or Oracle db < 4 to test so hopefully the CI does.
