Joshua Haberman	9bd23dab42	Changed upb status to suit GCC10's warning about strncpy(). (#268 ) Added tests for all cases. Also removed ellipses from truncated messages, they were more trouble than they are worth.	5 years ago
Joshua Haberman	08b6d2d6fd	Rewrite of the decoder (#263 ) New code is smaller (in both source size and compiled size) and faster. # Speed The decoder speeds up on all machines I tested, though the amount of speedup varies. I was only able to test Intel CPUs. ### Linux Desktop ``` CPU: Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz OS: Linux name old time/op new time/op delta CreateArena 4.72ns ± 0% 4.93ns ± 0% +4.47% (p=0.000 n=11+11) ParseDescriptor 12.4µs ± 1% 9.1µs ± 1% -26.65% (p=0.000 n=11+11) ``` ### Mac Laptop ``` CPU: Intel(R) Core(TM) i7-8850H CPU @ 2.60GHz OS: macOS name old time/op new time/op delta CreateArena 5.33ns ± 3% 5.58ns ± 2% +4.69% (p=0.000 n=12+12) ParseDescriptor 15.0µs ± 2% 11.9µs ± 2% -20.20% (p=0.000 n=12+12) ``` ### Linux Workstation ``` CPU: Intel(R) Xeon(R) Gold 6154 CPU @ 3.00GHz OS: Linux name old time/op new time/op delta CreateArena 5.29ns ± 0% 5.52ns ± 0% +4.37% (p=0.000 n=10+12) ParseDescriptor 18.6µs ± 0% 16.4µs ± 0% -11.54% (p=0.000 n=12+12) ``` # Size A few source files grow marginally because of some arena functionality moved inline.

Joshua Haberman	ca84145476	[decoder] fix for buf=NULL, size=0 case. (#246 )	5 years ago
Joshua Haberman	ca512852f3	Fixed parsing for string->double maps. (#243 ) Map parsing/serializing relies on map entries always having a predictable order. The code that generates layout was not respecting this in the case of string keys and primitive values.	5 years ago
Joshua Haberman	f9efbcd5d6	Added missing append fallback.	5 years ago
Joshua Haberman	059f226d41	Unit tests for maps generated code.	5 years ago
