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 FX_BSTR and FX_WSTR typedefs.chromium/2434chromium/2433chromium/2432chromium/2431chromium/2430Tom Sepez
These stand for const CFX_{Byte,Wide}StringC&, which is just monumentally confusing, since there are so many string types running around here. The following had manual changes: core/src/fpdfapi/fpdf_edit/fpdf_edit_content.cpp core/src/fpdfapi/fpdf_render/fpdf_render_loadimage.cpp core/src/fpdfdoc/doc_form.cpp fpdfsdk/src/fpdf_ext.cpp R=thestig@chromium.org Review URL: https://codereview.chromium.org/1180593004.
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

2015-05-28Fix ALL the include guards.Tom Sepez
Get rid of leading _CAPITAL identifiers. A large number of these didn't actually match the filename. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1160443004
2015-05-15Fix potential UAF in ConcatInPlace.Tom Sepez
If ConcatCopy somehow gets a zero nNewlen, it returns early, without allocating a new m_Data. ConcatInPlace then frees the old one, leaving m_Data dangling. Also be concerned about the multiplication in the widestring version. So use wmemcpy and let the library cope with it. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1130763007

2015-05-06Fix fx_string.h compile error under chromium checkouts.chromium/2398chromium/2397chromium/2396Tom Sepez
This gets included in chromium's pdfium_engine.cc, and thus must pass a higher error level. There's probably a follow-up to check why the FPDF_ api doesn't insulate chromium from this file. TBR=thestig@chromium.org Review URL: https://codereview.chromium.org/1127043004
2015-05-05Make sure string constructors are efficient on literalsTom Sepez
Separate out the overload when the length is not known, and be sure that strlen() call is in the header so that strlen("foo") => 3 (since many compilers support this optimization). Also delete some unused types. BUG=pdfium:151 R=thestig@chromium.org Review URL: https://codereview.chromium.org/1117263004

This reverts commit 15a62973b9b89c3e229cc0ab501c45967f91b325. Reason for revert: broke build on windows, mac. I must have missed some platform-specific conversions. TBR=brucedawson@chromium.org Review URL: https://codereview.chromium.org/1108883002
2015-04-27Kill operator LPCWSTR from CFX_WideString().Tom Sepez
This involves adding some explicit c_str() calls. Doing so flagged PDF_EncodeText() and FindOptionValue() as having suboptimal signatures, in that we are often throwing away a perfectly fine length and recomputing it. R=brucedawson@chromium.org Review URL: https://codereview.chromium.org/1101933003

2015-04-22Add missing operators for CFX_ByteStringC.Tom Sepez
Removing the implicit cast operator forces a build breakage should we use ByteStringC in STL containers. Adding an operator< restores correct behaviour. Adding an operator[] avoids re-writing some code to call GetPtr() prior to array indexing. Part 1 of 4. R=thestig@chromium.org TBR=brucedawson@chromium.org BUG=pdfium:142.

It's unused. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1098203002
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.

2015-01-21Simplify UTF16LE_Encode and add unittest.Bo Xu
Previously, UTF16LE_Encode take an optional flag to indicate if the returned byte string has trailing zeros. In fact, no where needs the flag to be false.

2014-12-08Replace manual/error-prone/hard-to-verify arraysize calculations with safe ↵Bruce Dawson
FX_ArraySize macro. pdfium has numerous places where the number of elements in an array is calculated with expressions like: sizeof(cFormats)/sizeof(FX_LPCWSTR) This is suboptimal because it is verbose, it is easy to get wrong, and it cannot be determined through casual inspection whether the code is correct. It will give incorrect results if cFormats is a pointer instead of an array and it will give incorrect results if FX_LPCWSTR is not the type of the array elements. The FX_WSTRC macro in fx_string.h which I fixed was particularly scary because it would silently misbehave if passed a pointer. The FX_ArraySize macro which I have added and started using (taken from arraysize in v8's macros.h) is easier to use and will always give correct results. If passed a pointer it will fail to compile. For this change I only fixed instances of sizeof(FX_LPCWSTR). There appear to be about 150 other places in the pdfium code that could benefit from using FX_ArraySize.

2014-12-08Getting rid of more (FX_LPCWSTR) casts and fixing two bugs revealed by this.Bruce Dawson
Since casts to FX_LPCWSTR have been shown to hide bugs I tried removing more of them, targeting those places where a cast was used to force a conversion from CFX_WideString to FX_LPCWSTR, replacing these casts with calls to the newly added .c_str() function. This revealed two places where the cast was hiding a bug -- where ->c_str() was required instead! This removes ~33 FX_LPCWSTR casts and there are ~31 left, many of which will go away in some future change. Also includes this change: Removing unnecessary casts from wchar_t* to wchar_t*, by various names.

2014-11-17Removing unnecessary casts from wchar_t* to wchar_t*, by various names.Bruce Dawson
Remove casts that merely cast from wchar_t* to wchar_t*. Sometimes the types or casts are FX_LPCWSTR but the idea is the same. Excess casts can (and have) hidden bugs so removing these may prevent future problems.
