2015-06-17Replace some Release() calls with virtual destructors.Tom Sepez
A virtual method that does |delete this| is an anti-pattern. Some classes can be de-virtualized instead. Throw in some unique_ptrs and delete dead code for good measure. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1192013002.

2015-06-11Kill FXSYS_mem{cpy,cmp,set.move}{32,8}.Tom Sepez
At one point in time, it may have made sense to indicate the expected alignment of the memory you're about to copy, but that was last century. The compiler will take care of it just fine. I stopped short of removing the FXSYS_ wrapper macros entirely. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1179693003.

2015-06-10Remove typdefs for pointer types in fx_system.h.Tom Sepez
This involves fixing some multiple variable per line declarations, as the textually-substituted "*" applies only to the first one. This involves moving some consts around following the substitution. This involves replacing some typedefs used as constructors with better code. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1171733003
2015-06-09Use stdint.h types throughout PDFium.Tom Sepez
It's redundant nowadays to provide our own equivalents, now that this is done for us by the system header. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1177483002
2015-06-08Remove more cruft from fx_system.hTom Sepez
- include system headers first and alphabetize. - remove unsupported FX_WIN32_MOBILE symbol. - actually define a FX_WIN64 symbol and make consistent. - use final/override, not FX_FINAL. - let stdint.h resolve FX_WORDSIZE concerns. - unused FX_ERR and FX_SUCCESS() macros. - unused FX_LSB_FIRST macro. - outline FX type deprecation plan. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1169963003
2015-06-04Move fx_safe_types.h to include/ directory.Tom Sepez
Small bit of OCD here, since this file is included cross-library (i.e. from fpdfsk), it can't be in src/. In other words, the following should be empty: grep -R 'include.*core/src/' fpdfsdk Fix some IWYU in it at the same time. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1147353006

2015-05-19Remove FX_Alloc() null checks now that it can't return NULL.Tom Sepez

2015-05-18Change FX_Alloc to FX_Try_Alloc in _JpegEncodeJUN FANG
This CL is used for: 1. keeping the same logic as before (the behaviour of FX_Alloc was changed for OOM). 2. fixing a potential integer overflow. BUG=N/A R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1126013006
2015-05-18Add safe FX_Alloc2D() macroTom Sepez
This avoids unchecked multiplications when computing a size argument to malloc(). Such an overflow is very scary, and can result in exploitable bugs. Along the way, kill off some return checks, since we know this can't return NULL. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1143663004
2015-05-15Fix leaks in embedder test's FlateEncode() usage and in FlateEncode().Lei Zhang
For FlateEncode(), error handling code leaked memory. R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1144603002
2015-05-15Abort on OOM by default in FX_Alloc().Tom Sepez
Add a FX_TryAlloc() for those few cases where we might need to continue in face of OOM. Remove FX_AllocNL() (the context of its use would suggest that NL means "No Limit"). This is used for some big allocations, so replace it with TryAlloc(). Large allocations may be worth trying to continue from, since there are few and they have a large chance of failing.

R=thestig@chromium.org Review URL: https://codereview.chromium.org/1084303002
2015-04-14Kill CFX_Object.Tom Sepez
CFX_Object is a type that implements its own new operators that return NULL on error. There's no need for this given the |new (std::nothrow)| syntax; in fact, the current code can only work if there is no activity in the constructors. This may explain the pervasive lack of constructors and reliance on Init() methods throughout the codebase. The activity takes place in fx_memory.h, where FX_NEW is mapped onto the std::nothrow syntax. The rest is just cleanup. Down the road, we will simply throw and remove all the error-checking paths for new objects. Landing this patch first will at least show a simple path back to the old behaviour without having to re-introduce CFX_Object should someone want to do so in their own fork.

2015-03-26Use correctly-typed error codes for fx_codec_jpx_unittestTom Sepez
Needed to fix the failed pdfium_unittests on windows. Ironically, I created these constants so I wouldn't mix up size_t's and off_t's in these tests, but I didn't apply them consistently. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1036743005

2015-03-19Fix subtle issues in opj_skip_from_memory and add unit tests.Tom Sepez
Follow on to https://codereview.chromium.org/990683002/. This more closely mimics what fseek() actually does, so as to avoid subtle bugs down the road. Move the DecodeData struct into a header so the test can use it, and provide a constructor for it. Along the way, I added include guards, removed the p_ prefix from some non-pointer vars, fixed some IWYU, and resolved some signed/unsigned comparison warnings with careful casting.

2015-03-16Fix a bug that JPX images can't be shownJUN FANG
In the process of opj_end_decompress, it will return fail when the end of coding stream is reached. However it returns true in the same scenario implemented in openJPEG. So the final solution is from openJPEG. Return true when the end of coding stream is reached. BUG=452671 R=tsepez@chromium.org Review URL: https://codereview.chromium.org/990683002

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.
