2015-12-16pb_istream_from_buffer: add const to prototypeAndrew Ruder2-6/+14
This commit changes the prototype for pb_istream_from_buffer from: pb_istream_t pb_istream_from_buffer(uint8_t *buf, size_t bufsize); to pb_istream_t pb_istream_from_buffer(const uint8_t *buf, size_t bufsize); This allows pb_istream_from_buffer users to point to const buffers without having to inspect code (to ensure practical const-ness) and then be forced to manually cast away const. In order to not break compatibility with existing programs (by introducing a const/non-const union in the pb_istream_t state) we simply cast away the const in pb_istream_from_buffer and re-apply it when possible in the callbacks. Unfortunately we lose any compiler help in the callbacks to ensure we are treating the buffer as const but manual inspection is easy enough.

Cmake updates
2015-10-15examples: cmake_simple: Use auto discovered pathKyle Manna1-2/+1
* No need to specify the src path and the module path. Let cmake do it.
2015-10-15cmake: Auto discover NANOPB_SRC_ROOT_FOLDERKyle Manna1-4/+6
* Use CMAKE_CURRENT_LIST_DIR to learn the path of the currently running file to determine location of NanoPB. * Simplifies use in other projects.
2015-10-15cmake: Build generator files in build directoryKyle Manna1-7/+24
Treat the source directory as immutable. Copy the generator directory which previously generated files in-tree to the build directory and then generate files. Many emerging continuous integration build systems test builds across multiple versions of dependencies protobuf and python versions in particular. The previous source tree builds resulted in stale files from the last build breaking the current build. By placing the build files in the build directory, the build system automatically removes stale files (removes output build directory) and regenerates them as necessary.

2015-10-05Fix regression in generating message size defines (issue #172).Petteri Aimonen6-9/+45
This bug was triggered when: 1. A .proto file included another .proto from a different directory. 2. The another .proto has an associated .options file. Added regression test for the same.

2015-10-01Fix bug in fuzzstub.Petteri Aimonen1-1/+1
The fread call always returned a message length of 1 byte, making the fuzz stub used for external fuzzers useless. The normal fuzztest.c was unaffected. Bug found using afl-fuzz.

decode: Fix compiler issue with gcc-5
2015-09-21decode: Fix compiler issue with gcc-5Kyle Manna1-1/+2
* gcc 5.0 and 5.1 appear to take issue with this line and generates the following error: /home/nitro/tmp/nanopb/pb_decode.c: In function ‘pb_decode_noinit’: /home/nitro/tmp/nanopb/pb_decode.c:889:60: error: conversion to ‘uint8_t {aka unsigned char}’ from ‘int’ may alter its value [-Werror=conversion] fields_seen[iter.required_field_index >> 3] |= (uint8_t)(1 << (iter.required_field_index & 7)); ^ * This seems like a compiler bug, but this workaround is harmless.
2015-09-21travis-ci: Use protobuf v3 as it adds python3Kyle Manna1-5/+3
* Still in testing currently.
2015-09-21travis-ci: Build C/C++/Python matrixKyle Manna1-10/+38
* Test a number of C compilers * Travis CI can't handle three languages (C, C++, Python) * Add support for swapping python2/3 binaries * Scons has made no attempts to support python3 yet: * Build the matrix manually * Scons doesn't inherit $CC/$CXX from parent environement, so pass compiler flags directly
2015-09-21generator: Use search $PATH for pythonKyle Manna1-1/+1
* Search $PATH for the python binary so that this works better with things like virtualenv as used on Travis CI
2015-09-20travis-ci: Initial working buildKyle Manna1-0/+28
* Initial working build for Travis CI build system.
2015-09-20generator: Fix strange unicode/str issue in python2Kyle Manna1-1/+8
* Work around this by checking the appropriate class for the given * environment.
2015-09-20generator: Attempt to simplify the str/unicode madnessKyle Manna1-0/+2
* This is a shot in the dark.
2015-09-20generator: Strings are utf-8 by default in python3Kyle Manna1-4/+2
* Not sure how to handle this case in python2, seems to work * Python 3 doesn't need this since all strings are utf-8
2015-09-20generator: Remove cmp() to work with Python3Kyle Manna1-5/+2
* Python3 ignores cmp() and __cmp__() and only needs __lt__() for sorting. Delete and update as appropriate. * Ref: https://docs.python.org/3.0/whatsnew/3.0.html#ordering-comparisons
2015-09-20generator: More exhaustive field size checkingKyle Manna1-15/+36
Create a FieldMaxSize class that: * Accumlates all C assertions * Handles the checking of the longest simple field * Also python3 doesn't support max(None)
2015-09-20generator: Use python2/3 binary read/write methodKyle Manna1-3/+4
* This works with python2 and python3
2015-09-20generator: Run python's 2to3 converterKyle Manna1-10/+11
* Invoked with `2to3 -w nanopb_generator.py` * No other changes.
2015-09-20cmake: Don't explicitly look for python2Kyle Manna1-12/+2
* Use the system python binary and make sure the generator works with both instead.
2015-09-20generator: Don't force python2Kyle Manna1-2/+1
Python2 is being phased out of the default python interpreter. Arch Linux has moved some time ago and upcoming Debian realeases will follow. My distro, Arch, doesn't have a python2-protobuf version, but does have a python3 version. With a python 2 & 3 compatible generator the exact interpreter can be ignored and can use the system default as most users expect. Update issue #155
2015-09-20Update changelogPetteri Aimonen1-1/+9
2015-09-20Add syntax specification to .proto files (issue #167)Petteri Aimonen33-13/+80
Eliminates a warning on protoc 3.0.
2015-09-13Fix maximum encoded size for negative enums (issue #166).Petteri Aimonen4-1/+87
2015-09-12Make the generator understand included files (issue #165).Petteri Aimonen6-36/+70
This will allow message sizes and enum options to be available across the include files. Currently searching for .options files for included files may not work for all path combinations, this is related to issue #116. Should probably make a pull request to protoc about that.
2015-09-12Refactor the generator logic into a ProtoFile class.Petteri Aimonen1-285/+297
In preparation for multi-file support in generator. No functional changes yet.
2015-09-12Expand the multiple_files test case to include oneofs and enumsPetteri Aimonen5-14/+48
2015-09-12Fix handling of unsigned 8- or 16-bit enums.Petteri Aimonen2-2/+18
Previously unsigned enums would throw errors on decoding if the value went outside the signed range (issue #164). Currently only helps for enums defined within the same file, but solving issue #165 will make it work for multiple files also.
