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.

2015-06-08Fix potentially massive memory leak in CPDF_DIBSource::LoadJpxBitmap().chromium/2429chromium/2428chromium/2427Lei Zhang
Leaks can happen in several places. For this particular bug, it happens when there is a colorspace component count mismatch. BUG=497191 R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1153633009
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
2015-06-03Kill unused IPDF_ classes.Tom Sepez
Some are simply never defined. Some are never instantiated. Some have paths that are never reached. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1168503003
2015-06-02kill IPDF_DocParser().Tom Sepez
Its fine to program to interfaces, but since the sole concrete implementation is in the same header as the interface, the code is bypassing it anyways. We can de-virtualize some things along the way, and remove two non-existent function prototypes from one of the headers. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1158053003
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
2015-05-21Fix four annoying warnings:Tom Sepez
Two "set but unused", one of which is surely an artifact from copying code around, and the other which ought to be used for the sake of clarity. Two are unknown "optimize" pragmas, remove them since the code has been shipped for years on other platforms under full optimization. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1148353002
2015-05-19Re-land: Remove FX_Alloc() null checks now that it can't return NULL.Tom Sepez
Fixes the ordering of some assignments broken when converting to checked numerics in CFX_PathData::AddPointCount(). Original Review URL: https://codereview.chromium.org/1142713005 R=thestig@chromium.org Review URL: https://codereview.chromium.org/1135893008
2015-05-19Revert "Remove FX_Alloc() null checks now that it can't return NULL."Tom Sepez
This reverts commit eb6527763171cdb4b0fbfea5a20d691f4d67b660. Reason for revert: broke javascript tests. TBR=thestig@chromium.org Review URL: https://codereview.chromium.org/1145843005
2015-05-19Remove FX_Alloc() null checks now that it can't return NULL.Tom Sepez
This permits some functions to become void's since they, in turn, can't fail. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1142713005
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
2015-05-15Fix leaks in the embedder tests themselves.Lei Zhang
Also change EmbedderTest::TearDown() to match the destruction order in Chromium's PDF code. R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1138143003
2015-05-15Remove FX_NEW_VECTOR() macros.Tom Sepez
There isn't much point in having macros that obscure obvious language features. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1135273004
2015-05-14Fix another batch of compiler warnings.Lei Zhang
Also fix typos and remove trailing spaces/tabs. R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1141123002
2015-05-11Create top-level public/ header directory.Tom Sepez
These are the only files that embedders of PDFium should be including. They are entirely self-contained, and compile cleanly against -Wall so as to not offend the code that may include them. Having done this, we can see that chromium is pulling in two additional files from the fpdfsdk/include/pdfwindow directory, which is not guaranteed to work. A few files are renamed, adding an "_" to make the names consistent. The exception is fpdfview, which is doc'd as such in the doc. Naturally, paths will need updating in a handful of files in chrome when this rolls in. BUG=pdfium:154 R=thestig@chromium.org Review URL: https://codereview.chromium.org/1135913002
2015-05-08Fix a bunch of -Wunused-but-set-variable warnings.Lei Zhang
Also fix a few nits and other errors along the way. R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1098583002

2015-04-27SEGV in CFX_BaseSegmentedArray::Iterate() when CS has malformed dictionary.Tom Sepez
Failure to check document-controlled value before using it. BUG=481363 R=palmer@chromium.org, thestig@chromium.org Review URL: https://codereview.chromium.org/1110653002
2015-04-27Reduce usage of 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. There are still some platform-specific code that needs the operator. R=brucedawson@chromium.org Review URL: https://codereview.chromium.org/1101933003
2015-04-27Revert "Kill operator LPCWSTR from CFX_WideString()."Tom Sepez
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

2015-04-22Add 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.

2015-04-17Set m_FontType in CPDF_Font() constructor.Tom Sepez
This can't change for the life of the object, so tidy up some wild uses throughout the code. Also kill pointless Initialize() method. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1060813003

Note: Landed on XFA first by mistake. Original review: https://codereview.chromium.org/1085963002/ TBR=brucedawson@chromium.org Review URL: https://codereview.chromium.org/1090463002
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.

2015-04-11Fix a heap buffer overflow issue in CPDF_CMap::GetNextCharJUN FANG
Add a check to make sure offset is less than the size of string in the function of GetNextChar(). BUG=471651 R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1067073003
2015-04-10Fix a stack overflow in CPDF_Parser::LoadCrossRefV5JUN FANG
A stack overflow was triggered by checked_cast due to invalid index in pdf files like 'Index[45 -1661]'. BUG=473400 R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1054303005
2015-04-10Don't call FPDF_InitLibrary() in individual unit_tests.Tom Sepez
The initialization sequence becomes more complicated as v8 evolves and when we move to XFA (where pdfium_unittests are currently broken). Centralize this initialization in a few places, like the embedder_test framework and the pdfium_test binary, and convert tests that require it into embedder_tests rather than unit_tests. Change on master first before moving to XFA. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1071343002
2015-04-09Fix a global buffer overflow in GCPDF_CIDFont::_CharCodeFromUnicodechromium/2368chromium/2367chromium/2366chromium/2365chromium/2364Jun Fang
There is not a code page (CP) used for converting unicode to mutli-bytes if the coding scheme is CID coding. Only return 0 if CID can't be retrieved. The difference on Windows and other platforms should be the function used for converting rather than others. BUG=466790 R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1074653002

2015-04-03Add embedder test comparing with the last patch.JUN FANG
When there is a wrong keyword like '??ze' in the dictionary of the trailer, PDFium can't recognize it and aborts further parsing. After this change, PDFium continues even it can't get the right size at this moment. It will rebuild the cross reference table later since the size of the table is missing.

Original review URL https://codereview.chromium.org/1009513003 Reason for revert: New "corpus" tests show that this is no longer rendering some images.

2015-03-16Fix a problem that JP2 image is not displayed because index color space is usedJUN FANG
There are two issues in this bug. One is that JP2 image is not displayed because it aborts loading Jpx bitmap when the number of components in color space is different with that one in JPX images. I found that the number of components in color space isn't updated after it's initialized. For index color space, the component shall inherit from its base color space. The second issue is that displayed color is not correct after I fixed the first issue. The root cause is that sRGB is used in JPX image, it doesn't need to map from index to RGB again.
