Re: [Rpm-maint] [rpm-software-management/rpm] Adding header tag formats to generate UUIDS (#269)
Meanwhile this patch adds a --queryformat modifier to generate UUID's from tag values, which is an entirely orthogonal and mostly non-intrusive usage case than converting hdrNum/tagNum to an octet string. -- You are receiving this because you are subscribed to this thread.

Re: [Rpm-maint] [rpm-software-management/rpm] Adding header tag formats to generate UUIDS (#269)
Changing indices to be octets (rather than integers) is a prerequisite to using UUID's as a join key. There are many problems (endianness, exposure of hdrNum/tagNum in the RPM API) that need to be solved to use a UUID as an octet string for LMDB (and for BDB). See other issues for work-in-progress. Ideally, a UUIDv1 (which has time ordered properties) should be used as the retrieval key throughout all RPM backend databases. One of the immediately obvious and useful side effects is that "rpm -qa" will present results in install order by default, which is more deterministic (and less confusing imho) than random hash bucket iteration returns. -- You are receiving this because you are subscribed to this thread.

It didn't seem like you used this with the LMDB implementation (ed9de1992f5e1c23e8d8dbd61325a1e0070f2c72), though you mention it as a starting point. I'm guessing you're not currently using it? Or did I miss something? -- You are receiving this because you are subscribed to this thread.
