2016-07-15Use CPDF_Dictionary::SetAtReference instead of CPDF_Dictionary::AddReference.jaepark
The definitions of CPDF_Dictionary::SetAtReference and CPDF_Dictionary::AddReference are identical, and AddReference is only used once. So remove CPDF_Dictionary::AddReference method and use CPDF_Dictionary::SetAtReference instead. Review-Url: https://codereview.chromium.org/2161453002
2016-07-11Use smart pointers for class owned member variablesweili
Replace raw member variables to smart pointer type to better maintain the ownership and to ease the management. BUG=pdfium:518 Review-Url: https://codereview.chromium.org/2136683002
2016-06-23Improve hint table validation checks.thestig
Check required hint table dictionary entries and make sure they: - Exist. - Are of the right type. Along the way: - Fix FX_atonum() to not have a non-const pass-by-ref param. - Simplify code in CPDF_StreamContentParser. - Make CPDF_Number::IsInteger() a const method.

2016-06-22Fix memory leaks in EmbedderTest::OpenDocument().thestig
EmbedderTest::OpenDocument() does not gracefully handle the case of being called twice in a given test case. So avoid doing that. Review-Url: https://codereview.chromium.org/2088093002

2016-06-13Make code compile with clang_use_chrome_plugin (part I)weili
This change contains files in core/fpdfapi directory. This is part of the efforts to make PDFium code compilable by Clang chromium style plugins. The changes are mainly the following: -- move inline constructor/destructor of complex class/struct out-of-line; -- add constructor/destructor of complex class/struct if not explicitly defined; -- add explicit out-of-line copy constructor when needed; -- move inline virtual functions out-of-line; -- Properly mark virtual functions with 'override'; -- some minor cleanups; BUG=pdfium:469 Review-Url: https://codereview.chromium.org/2060973002

It's possible for the hint table to not exist event though we have a hint key in the object database. If the table does not exist then return false from CheckHIntTables(). BUG=pdfium:512 Review-Url: https://codereview.chromium.org/2047723002

2016-06-03Fix some code which causes warnings when compiled by /analyze toolweili
The code may not cause error conditions, but can be improved. These warnings include uninitialized variables, signed/unsigned mismatch, redundant condition, and using bool in arithmetic operations. Also remove a chunk of unused code. BUG=chromium:613623, chromium:427616 Review-Url: https://codereview.chromium.org/2036203004
2016-06-02Fix all the code which has duplicate variable declarationsweili
When there are duplicate variable declarations, the inner names shadow the outter ones. This is error prone and harder to read. Remove all the instances found by /analyze. BUG=chromium:613623, chromium:427616 Review-Url: https://codereview.chromium.org/2027273002

2016-05-25Remove CFX_PrivateData from CPDF_Documenttsepez
Replace it with two generic slots for Links and Codec usage. Since the codec is at a lower layer than the document, we don't provide separate get/set methods, since having a document upon which to call these would be a layering violation. Do the same for the Links for simplicity. Review-Url: https://codereview.chromium.org/2005193003

2016-05-13Make CFX_ByteString(const CFX_ByteStringC&) explicit.tsepez
Add missing helper function to CFX_ByteTextBuf to avoid the anti-pattern CFX_ByteString(sBuf.AsStringC()), using the name "Make" to indicate there's an allocation going on in this case. Change some method arguments to take pre-existing ByteStrings where possible. Review-Url: https://codereview.chromium.org/1977093002
2016-05-12Add CFX_ByteStringC::CharAt() to avoid c_str() and casts.tsepez
Most of the time, we want to operate on chars as if they were unsigned, but there are a few places where we need the default (questionably signed) values. Consolidate the casting in a single place rather than forcing callers to get a char* ptr. BUG=pdfium:493 Review-Url: https://codereview.chromium.org/1972053003

2016-04-29Relax a couple checks to allow certain non-standard PDF files.weili
Some non-standard PDF files misuse the size of cross reference table, and reuse some object number which the old one is still in use. PDFium can relax the reusing of xref objects only since it is not referred in the pdf document. When the size of cross reference table is larger than defined, PDFium will try to continue other than abort. BUG=chromium:596947 Review-Url: https://codereview.chromium.org/1926823002
2016-04-27Standardize on ASSERT.dsinclair
There are currently three ways to assert in the code (ASSERT, FXSYS_assert and assert). This CL standardizes on ASSERT. The benefit of ASSERT is that it can be overridden if the platform requies and we can pickup the Chromium version if it has already been defined in the build. This does change behaviour. Currently FXSYS_assert is always defined but ASSERT is only defined in debug builds. So, the FXSYS_assert's would fire in Release builds. That will no longer happen.

2016-04-26Remove several IPDF_ interfaces and CPDF_RenderModule.dsinclair
This CL removes the interfaces: * IPDF_ObjectRenderer * IPDF_OCContext * IPDF_RenderModule * IPDF_PageModule The CPDF_RenderModule was just wrapping new and delete calls. This Cl moves those up to the callers and removes the CPDF_RenderModule class. Review URL: https://codereview.chromium.org/1918323003
2016-04-22Add a simple check for V4 cross reference tableweili
Some unknown software generates cross reference table with the claimed object numbers are all off by one. Add a simple verification function to detect this scenario, thus have a chance to rebuild the correct cross reference table. To avoid unnecessary checks and potiential performance hit, we only check for the very first non free entry. BUG=602650 Review URL: https://codereview.chromium.org/1910063004

2016-04-20Standalone GN build.dsinclair
This CL setups up a standalone GN build. You'll need to set gn args similar to: use_goma = true clang_use_chrome_plugins = false pdf_enable_xfa = true pdf_enable_v8 = true pdf_is_standalone = true The third_party/pymock files are needed to make git cl upload work correctly.

2016-04-15Avoid narrowing to StringC in CPDF_Name and CPDF_NameTreetsepez

2016-04-14Rename CFX_ByteTextBuf::GetByteString() to AsStringC().tsepez
Do the same for CFX_WideTextBuf as well. The name is confusing because these return CFX_ByteStringC, not CFX_ByteString. The AsStringC naming gives parallelism with the string types themselves, and may help to indicate that the result is only good for the lifetime of the object being operated upon. Review URL: https://codereview.chromium.org/1886263003
2016-04-14Make CPDF_Dictionary methods take CFX_ByteString argumentstsepez
This will help avoid duplicate allocation of CFX_ByteStrings when the caller already has one. It may seem counter-intuitive that requiring the caller to pass an allocated CFX_ByteString rather than a static CFX_ByteStringC would improve the situation, but due to the idiosyncrasies of std::map, the CPDF_Dictionary methods must always do an allocation under the covers which can't be avoided. The changed callers in this CL are places where we would previously demote to CFX_ByteStringC and then allocate a a duplicate CFX_ByteString in the dictionary method.

2016-04-12Remove ICodec_* Interfaces.dsinclair
All of the ICodec_* interfaces had a single implementation. This CL removes the interfaces and uses the concrete classes in their place. BUG=pdfium:468 Review URL: https://codereview.chromium.org/1876023003
2016-04-11Remove CPDF_Object::GetConstString and overridestsepez
GetConstString() has sharp edges in that when applied to a CPDF_Number, it must return null whereas GetString() returns a the stringified number, because of the inability to control the lifetime of the underlying allocated string. Deleting this method showed several places where we actually wanted a *String, not a *StringC, so we were re-allocating a string we already had. Review URL: https://codereview.chromium.org/1879683002
