Joshua Haberman	9df96874e9	Start arena block doubling at initial block size. If an initial block is provided, we should start our block doubling at the size of the initial block, not 128. This saves us from unnecessary overhead when we overflow the initial block.	4 years ago

Joshua Haberman	5b1f0d86a1	For Kokoro, only build/test -m32 on Linux. Also fixed a bunch of bugs found by gcc's -fanalyzer.	4 years ago
Joshua Haberman	0497f8deed	Fixed a critical bug on 32-bit builds, and added much more Kokoro testing. There was a bug in our arena code where we assumed that sizeof(upb_array) would be a multiple of 8. On i386 it was not, and this was causing memory corruption on 32-bit builds.	4 years ago
Joshua Haberman	64abb5eb11	Amalgamation no longer bundles wyhash, but #includes it. Also fixed a few spelling mistakes.	4 years ago
Joshua Haberman	dd0994d377	Bugfix for JSON decoding: only check real oneofs for duplicates. Also fixed upb_msg_whichoneof() to work properly for synthetic fields, and to be simpler in general.	4 years ago
Joshua Haberman	c9f9668234	symtab: use longjmp() for errors and avoid intermediate table. We used to use a separate "add table" during the upb_symtab_addfile() operation to make it easier to back out the file if it contained errors. But this created unnecessary work of re-adding the same symbols to the main symtab once everything was validated. Instead we directly add symbols to the main symbols table. If there is an error in validation, we remove precisely the set of symbols that were already added. This also requires using a separate arena for each file. We can fuse it with the symtab's main arena if the operation is successful.

Joshua Haberman	f2d826b9f3	Got rid of floating-point division in table init. Ideally we would get rid of all floating-point operations in table.c, but that's a job for another day.	4 years ago
Joshua Haberman	154f2c25f4	Added UTF-8 validation for proto3 string fields.	4 years ago
Joshua Haberman	e8f9eac68c	Added #defines UPB_ENABLE_FASTTABLE and UPB_TRY_ENABLE_FASTTABLE. These control whether fasttable decoding is on.	4 years ago
Joshua Haberman	e86541ac1d	Fixed the build after the merge.	4 years ago
Joshua Haberman	8f3ee80d46	Drop C89/C90 support and MSVC prior to Visual Studio 2015. upb previously attempted to support C89 and pre-2015 versions of Visual Studio. This was to support older compilers with limited C99 support (particularly MSVC). But as of last August, even gRPC has dropped support for MSVC prior to 2015 `c87276d058` Therefore it seems safe for upb to no longer attempt C89 support (we were already not truly C89 compliant, with our use of "bool"). We now explicitly require C99 or greater and MSVC 2015 or greater. This cleaned up port_def.inc a fair bit. I took the chance to also remove some obsolete macros.	4 years ago
Joshua Haberman	2c8bb6dd9d	Specify C99 explicitly until/unless we stop using bool.	4 years ago
Joshua Haberman	efd576b698	Added -std=gnu99 for fastdecode and ran Buildifier.	4 years ago

Joshua Haberman	46eb82467a	Added comment to decode_fast.h.	4 years ago
Joshua Haberman	bd9f8f580d	Fixed a few bugs with the fast decoder. 1. For long tags we were putting table entries in the wrong slot. 2. For repeated strings, when the buffer flipped to no longer alias we were failing to notice and kept aliasing anyway.	4 years ago
Joshua Haberman	021db6fcd5	Allow larger tags into the table if they are unique mod 31. Also fixed a bug with fixed packed in decode_fast.c.	4 years ago
Joshua Haberman	86d9908c55	Fastdecode support for packed fields. This is not very optimized yet. There is a lot of room to optimize it further.	4 years ago

Joshua Haberman	48689df72e	Eliminated bounds checks inside parsing a field. Each field parser gets 16 bytes of slop. This requires using a patch buffer at end-of-buffer.
