Regression test + fix for proto3 submessage improperly considered empty
|
|
|
|
This will only occur with unlimited length streams, so it's kind-of
low impact. Such streams allow denial of service anyway.

Repeated callback fields were being treated as "always present",
even if the callback pointer wasn't set.

Previously nanopb didn't enforce that decoded bool fields
had valid true/false values. This could lead to undefined
behavior in user code.
This has potential security implications when
1) message contains bool field (has_ fields are safe)
and
2) user code uses ternary operator dependent on the field value,
such as: int value = msg.my_bool ? 1234 : 0
and
3) the value returned from ternary operator affects a memory access,
such as: data_array[value] = 9999

This could happen with zero-length submessages and strings.
While technically valid, it is an useless call and a rare
corner case that can easily lead to bugs in the callback
implementation.

Previously the example code would falsely detect EOF condition if
called with count = 0.

Don't encode scalar arrays as packed. This is only to be used when
the decoder on the receiving side cannot process packed scalar arrays.
Such example is older protobuf.js.

Unsorted enums in message specifications do not result in correct
min/max values per the protobuf spec for cpp code:
https://developers.google.com/protocol-buffers/docs/reference/cpp-generated#enum
The google cpp compiler uses the min/max _value_ instead of the position
of the enum entry in the message spec, so this patch updates nanopb to
do the same.
Example input:
```protobuf
syntax = "proto3";
enum Language {
UNKNOWN = 0;
ENGLISH_EN_GB = 12;
ENGLISH_EN_US = 1;
FRENCH_FR_FR = 2;
ITALIAN_IT_IT = 3;
GERMAN_DE_DE = 4;
SPANISH_ES_AR = 13;
SPANISH_ES_ES = 5;
SPANISH_ES_MX = 14;
SWEDISH_SV_SE = 6;
DUTCH_NL_NL = 7;
KOREAN_KO_KR = 8;
JAPANESE_JA_JP = 9;
CHINESE_SIMPLIFIED_ZH_CN = 10;
CHINESE_TRADITIONAL_ZH_TW = 11;
}
```
This would previously result in:
```c
#define _Language_MIN Language_UNKNOWN
#define _Language_MAX Language_CHINESE_TRADITIONAL_ZH_TW
#define _Language_ARRAYSIZE ((Language)(Language_CHINESE_TRADITIONAL_ZH_TW+1))
```
After this patch,
```c
#define _Language_MIN Language_UNKNOWN
#define _Language_MAX Language_SPANISH_ES_MX
#define _Language_ARRAYSIZE ((Language)(Language_SPANISH_ES_MX+1))
```
Add a test `enum_minmax` to cover this case.

Add 32BIT and 16BIT compile time flag for nanopb library to support
16BIT or 32BIT size, default is 8BIT. User need to use the corresponding
library when define the PB_FIELD_* flag during compilation.
