Adam Rocska 3f4914190d A strategy emerged on how to process MaxMindDB data. May not be the best, but it could work.

Adam Rocska 6449c653b2 It works. The motto should still remain "RTFM". Signed integers arrive as two's complement instead of signed magnitude (duh).

Adam Rocska 438c0eca44 Doing a commit, to save the state. But will remove truncation logic at all, and just simply set a precondition. MaxMind's DB format could possible have an "overflow case" happen, but it just won't be supported.

Adam Rocska 9adc855359 Work in progress with the decoder. I want to avoid creating a copy in memory just because maxmind's binary data format sucks jack's shit...

Adam Rocska bac7cedd36 Renamed the file from SafeIndexOffset to LimitedIndex & its test. I think it's more expressive.

Adam Rocska 92806b035d I really needed these limitedIndex accessors. I don't know if it's an anti-pattern with Swift or not, but I couldn't find another way around.

Adam Rocska 09469628e3 The quick and dirty implementation for lastIndexOf. I'll make it a bit nicer (definitely not faster), and move on.

Adam Rocska 1f80a1ac6e Syncing github repo with local experiments : 
- Reader now has the data separator defined as is.
- removed dead dummy playground code from MetadataStructTest.swift
- started to work out a last index of concept (naïve one of-course)

Adam Rocska b020fb2944 Finally got a concept on how to program this in a non-convoluted way. 
- Extended UInt8 with a nice and juicy bitmask helper function
- Foundation for a ControlByte type

Adam Rocska 311cdc3342 Figured out a rather unorthodox, and unsafe way of transforming `Data` to certain Swift types. Will come in handy to represent the MaxMindDB somehow.

Adam Rocska a98db16edb Bugfixing in the search algorithm. 2020-04-29 15:53:22 +02:00
Adam Rocska 661125fc80 I was an inattentive prick, and misimplemented the algorithm. It works now. 2020-04-29 13:29:16 +02:00
Adam Rocska c0dba1887b Committing half made not working code to ask for some help. The search algorithm gets stuck at index 20990 as if it was an overflow, while it can't be an overflow, since it's a typealias for Int, and also, it's not a square number. Weird. Bughunting. 2020-04-29 13:03:10 +02:00
Adam Rocska 3173807987 Removed submodules, and doing stuff. 2020-04-28 11:08:31 +02:00
Adam Rocska 4fc53d970c I figured out what the problem was. I was an idiot in many ways : 
- the submodule had an invalid detatched head commit hash. Dunno why.
- the package swift file defined a wrong version number for libmaxminddb. Moral of the story : don't be an ass.
- some leftover garbage from automake made me believe I was done
- potato
