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.

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.

2015-04-10Fix the noisiest variable shadowing warnings in pdfium.Bruce Dawson
Three functions in fx_coordinates.h account for 60% of the warnings when building with VS 2015, due to variable shadowing. Renaming the function parameters is safe, resolves the warnings, and reduces confusion. R=tsepez@chromium.org BUG=440500 Review URL: https://codereview.chromium.org/1077083003

2015-03-12Kill CFX_GrowOnlyPool.Tom Sepez
It's unused, and when the time comes, we'll want to put pdfium onto a hardened allocator like partitionAlloc anyways. Along the way, merge adjacent #ifdef __cplusplus blocks, remove a pointless check for __cplusplus inside a .cpp file, and remove a redundant cast.

2015-01-26Fix infinite recursion in CPDF_Parser::ParseIndirectObjectAt().Tom Sepez
A suitably corrupted file can cause the parser(s) to repeatedly re-read sections of the file at increasing parser recursion depth until the stack is exhausted. There is supposed to be a check for this based upon the parser "level", but not all call paths pass or update the level as required. Much as I hate per-class statics, this introduces one to track the depth so that the check is enforced no matter how screwy the call path might be that leads the parser to re-enter itself. This is more palatable than trying to find all these paths and fix them. We know this is OK since there is only one thread in here modifying the static.

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. So just get rid of it so callers won't misuse. The bug is found by https://codereview.chromium.org/837723009 R=tsepez@chromium.org Review URL: https://codereview.chromium.org/860973002
2015-01-09Fix -Wnon-virtual-dtor compiler warnings.Tom Sepez
This is done by explicitly adding a virtual dtor to interface classes, since the cost is small given that there are already virtual functions. The exceptions are for classes that have a Release() or Delete() method, in which case it is non-virtual and protected to indicate that the virtual class is never the deletion point.

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.

2014-11-18Fixing format strings to remove 'z' size specifier.Bruce Dawson
As of the 2013 version VC++ still doesn't support the 'z' size specifier. This makes portable printing of size_t types frustrating. The simplest general solution is to use %u and cast to unsigned. If there was any possibility of the numbers getting larger than 32-bit then we would need better alternatives, but there is not. This was found through code inspection, through /analyze, and through pdfium_test print this non-helpful message: Loaded, parsed and rendered zu pages. Skipped zu bad pages. I can confirm that the fix works on Windows and it should work identically on mac. This is a follow-on to change 02e6ca4c4f. R=tsepez@chromium.org Review URL: https://codereview.chromium.org/738433003
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.

2014-08-13Add FX_OVERRIDE and use it for virtual functions of FX_FINAL classes.Tom Sepez
Should there be cases where this fails to compile, it indicates a mistake, either an incorrectly declared overrriden virtual method, or a method that should be declared non-virtual. The only issues were with CPDF_CustomAccess::GetBlock(), CPDF_CustomAccess::GetByte(), and CPDF_CustomAccess::GetFullPath(). These don't appear to be used anywhere, and are removed. Two members are removed that are no longer needed once those methods are removed. R=jam@chromium.org, jun_fang@foxitsoftware.com Review URL: https://codereview.chromium.org/454983003
