ESqueak v3.8 ASN1 spec
by rabbit 26 Dec '22

26 Dec '22

Hey y’all, Merry Christmas! I’m a hacking ASN1, atm. I’ve eviscerated the ASN1 tagging to add class tags. I’m getting close! More below… First, Yes! I got my release.1 ParrotTalk / Local Promises build re-stabilized! Installer ss project: ‘Cryptography’; install: ‘ESqueak.release.1’. I reworked Linda to remove the mutex and also got an ordered queue working out of the ENotWaitingLinda implementation using my new method: NotWaitingTupleSpace>>#select:sort:ifNone: This is in the remote promises pre-release of ESqueak…it’s #BROKEN but being actively worked on… Installer ss project: ‘Cryptography’; install: ‘ESqueak.release.3’. ••• ASN1 tagging for ParrotTalk v3.8 ••• Here’s the new tagging … Well, I’m going to deprecate version 3.6 and 3.7 of ParrotTalk in favor of version 3.8 in order to support bridging and brokers. This will be done to provide network fault tolerance by replicating connections, as well as provide resilience to DDOS attacks by going through bridges with the replication. We shall see if it delivers. These are in the Private class tag. I will post the ASN1 private class numerical tagging for these messages. I will still have six tags available for future use. Tag 0 & 1 are errors, one for duplicate and one for absence. Tag 2 will be for non-defined named structures <ad-hoc classes, passed by value> to encode structures in classes that are not previously defined. ••••••• ParrotTalk v3.8 ASN1Tags ••••••• Layer 5: Parrot – session v3.8 Errors <0> Duplicate <1> NotFound Common <2> AdHocNamedStructure <3> RawData <4> Encoded <5> Encrypted <6> MAC —- ParrotTalk v3.8 —- • Broker Registration :: <7> Hallo_Makler • Broker Response :: <8> Antwort_Vom_Makler • Lookup Contact :: <9> Kontakt_Suchen • Contact by Bridges :: <10> Kontakt_Durch_Brücken • Hello Bridge :: <11> Hallo_Brücke • Bridge Response :: <12> Antwort_Vom_Brücke • Hello Contact :: <13> Hallo_Kontakt • Contact Response :: <14> Antwort_Vom_Kontakt • General Signature :: <15> Signature Layer 6: Remote Promises ••• 16-20 (EventualMessages) <16> DeliverMessageOp <17 > DeliverOnlyMessageOp <18> GCAnswerOp <19> GCExportOp <20> ShutdownOp ••• 21-25 (EventualDesc) <21> GiftPromiseDesc <22> FarDesc <23> RemotePromiseDesc <24> ImportDesc <25> IncomingDesc ••• 26-31 Naming Replication <26> [AVAILABLE] <27> [AVAILABLE] <28> [AVAILABLE] <29> [AVAILABLE] <30> [AVAILABLE] <31> [AVAILABLE] ••• 𝙄𝙛 𝙮𝙤𝙪 𝙖𝙧𝙚 𝙙𝙧𝙞𝙫𝙞𝙣𝙜 𝙖 𝙋𝙤𝙧𝙨𝙘𝙝𝙚, 𝙩𝙝𝙖𝙣𝙠 𝙮𝙤𝙪 𝙛𝙤𝙧 𝙢𝙤𝙫𝙞𝙣𝙜 𝙤𝙫𝙚𝙧, 𝙨𝙤 𝙩𝙝𝙖𝙩 𝙄 𝙘𝙤𝙪𝙡𝙙 𝙨𝙖𝙛𝙚𝙡𝙮 𝙥𝙖𝙨𝙨!

ASN1ExplicitContextValue classTag?
by rabbit 25 Dec '22

25 Dec '22

Hey Ron, all, I am eviscerating asn1Tagging in ASN1 to support class tagging and I ran into a question regarding a class you had introduced for your DefinitionModel. The ASN1FieldDefinition uses a tagType to derive the classTag. However, the ASN1ExplicitContextValue seems not to specify. Should I be assuming Context-specific as it is used inside Wrappers and Choices? Regarding the general use of the DefinitionModel...I think I would like to specify ASN1 encoding using the declarational model, but I also like the in-image structured object representation of my #initializeASN1Types construction. Why not both?! SO the challenge is to use your Definitional model to produce the structure and vice-a-versa, generate the declarational text from the structure. As always, (22 years!) this is a work in progress, but now with the deadline of my 29th Physics Reunion at my Guilford College. I am furiously at work again, hoping my hypomania continues! :) -- 𝙄𝙛 𝙮𝙤𝙪 𝙖𝙧𝙚 𝙙𝙧𝙞𝙫𝙞𝙣𝙜 𝙖 𝙋𝙤𝙧𝙨𝙘𝙝𝙚, 𝙩𝙝𝙖𝙣𝙠 𝙮𝙤𝙪 𝙛𝙤𝙧 𝙢𝙤𝙫𝙞𝙣𝙜 𝙤𝙫𝙚𝙧, 𝙨𝙤 𝙩𝙝𝙖𝙩 𝙄 𝙘𝙤𝙪𝙡𝙙 𝙨𝙖𝙛𝙚𝙡𝙮 𝙥𝙖𝙨𝙨! 𝘼𝙧𝙧𝙞𝙫𝙚𝙙𝙚𝙧𝙘𝙞, 𝙧𝙖𝙗𝙗𝙞𝙩 🐰
