2014-09-02Tidy up opj_ callback functions in fx_codec_jpx_obj.cppTom Sepez
This is code cleanup rather than bug fixing. The motivation for this was to fix the casts at line 97 of the original file. These are wrong; you cannot correct via casting a function signature mismatch when passing a function as an argument. In theory, there's no reason to believe that the compiler will pass args in the same manner for a function of type (void*, size_t, void*) as for a function of type (void*, size_t, some_struct*). The cast will suppress the compile error, but you can't be assured the call will work as intended. In practice, it does, since the last architecture where a void* had a different representation than a struct* went extinct in the late 80s. In the functions themselves, note that we currently bail out if srcData->offset >= srcData->src_size, so the expression bufferLength = (OPJ_SIZE_T)(srcData->src_size - srcData->offset) will always be > 0. Hence the check if(bufferLength <= 0) is pointless, esp. since bufferLength is a signed type and < 0 makes no sense. The opj_seek_from_memory() has a bool return value, so returning -1 on error doesn't seem reasonable. Change this to TRUE/FALSE, and return false on seek past end. If we're truly passing readonly data, then perhaps it makes sense to make the write() function always return -1. I didn't do this. Lastly, I capitalize "DecodeData" so that it looks like a struct, and change its members to be size_t's to avoid casting back and forth.

Since the land of https://pdfium.googlesource.com/pdfium/+/3522876d5291922ddc62bf1b70d02743b0850673, memory is assured to be 16 byte aligned. So no need to do this check.

2014-05-20Fixed or silenced all warnings and turned on warnings-as-errors.John Abd-El-Malek
- Silence -Wheader-hygiene warning on Clang. Between fx_agg_driver.cpp and fxjs_v8.h there are hundreds or thousands of things that depend on "using namespace", so it is best to just suppress this warning than fix it. - gzguts.h: Include unistd.h on all non-Windows platforms, not just Apple platforms. Fixes implicit include warnings on Linux. - Added parens to silence a warning about mixing && and ||. - Removed a check if an enum is negative. Enums can be unsigned, generating an always-false warning. The check isn't necessary. - Removed some statements that are just names of variables that do nothing.
