2016-09-23Avoid collisions in CPDF_IndirectObjectHolder::AddIndirectObject()tsepez
The change at 5b7c9bb differed from the original code in that a pre-existing object would now be freed, which showed that a collision could be possible if m_LastObjNum overflowed. BUG=649206 Review-Url: https://codereview.chromium.org/2361303002

2016-09-22Rename CPDF_CountedObject to CFX_WeakPtr::Handlechromium/2869tsepez
This better describes its purpose, and reduces confusion with the CFX_CountRef class, which is unrelated. The WeakPtr class itself that manipulates handles is NYI. Review-Url: https://codereview.chromium.org/2366673003
2016-09-22Make creation of CPDFSDK_Document clearerdsinclair
Move the creation of the CPDFSDK_Document into FPDFDOC_InitFormFillEnvironment instead of hidden inside a Get method in CDPFXFA_Document. Review-Url: https://codereview.chromium.org/2353303004

Handle the case that GrowNamedColorList return fail when list is too long. Otherwise the loop never ends. Found by libfuzzer Review-Url: https://codereview.chromium.org/2365663002
2016-09-22Null CPDF_CountedObj::m_pObj prior to deletiontsepez
This gives additional protection in case of re-entry. Also make CFX_CountRef more robust in face of errors. BUG=649229 Review-Url: https://codereview.chromium.org/2364673002
2016-09-22Rename App to Env where needed.dsinclair
More instances of CPDFSDK_Environment being called m_pApp in the code. Renamed to m_pEnv to be clear that it's the environment not an app object. Review-Url: https://codereview.chromium.org/2354413002
2016-09-22Simplify memory management for per isolate dataweili
Use smart pointers for FXJS_PerIsolateData owned member variables. Also move creation and deletion of dynamic object map into FXJS_PerIsolateData's constructor and destructor. Overall, the interfaces and memory management should be simpler. BUG=pdfium:518 Review-Url: https://codereview.chromium.org/2358343002

2016-09-22Move CPDFSDK_Environment code to cpp filedsinclair
This CL moves the code from the .h file into the .cpp file. Review-Url: https://codereview.chromium.org/2354363003
2016-09-21Remove some objnum locals with AddIndirectObjecttsepez
Also, it's idempotent, so simplify some logic in callers to not care if objnum is zero. The alternate forms are rarely used, using the objnum form makes it clear that SetReferenceFor() can't possibly register the object as a side-effect. Review-Url: https://codereview.chromium.org/2361713002
2016-09-21Move win_xfa_clang bot back into regular commit queueweili
win_xfa_clang bot was marked as experimental due to https://crbug.com/626120 which was fixed a while ago. Now no longer need to keep it as experimental. Review-Url: https://codereview.chromium.org/2363603002

Review-Url: https://codereview.chromium.org/2358243002
2016-09-21Make ownership explicit in CPDF_ContentMarkItem.tsepez
The old SetParam() method had "maybe take ownership" semanitcs based upon the type argument. Make GetParam() handle the None case and simplify callers based upon that behaviour. Review-Url: https://codereview.chromium.org/2358043003
2016-09-21Check for overflow in CMap_GetCode.dsinclair
Given a large enough value for the character code it's possible to overflow the conversion to an int. This Cl updates the code to guard against overflow. BUG=chromium:648739 Review-Url: https://codereview.chromium.org/2358023002
2016-09-21Avoid static initializers and global variables in 'pdfium_test'.tonikitoo
This CL aims to follow up on thestig's past-land feedback receveid on https://codereview.chromium.org/2277063003/#msg15 . In order to avoid static initializers and global data declaration, CL adds a data struct named PDFiumTest_FPDF_FORMFILLINFO, which has FPDF_FORMFILLINFO as the first struct member definition. This allows the use of reinterpret_cast to/from PDFiumTest_FPDF_FORMFILLINFO and PDF_FORMFILLINFO. PDFiumTest_FPDF_FORMFILLINFO also two more struct members, 'loadedPages' and 'formHandle', which were previously global variables. Review-Url: https://codereview.chromium.org/2330043002
2016-09-21Clear LeakSanitizer's suppression listweili
We have cleared all the leaks in our code. There is no need for those suppressions. Plus, most of them are obsolete due to code refactoring. Still keep this file around so that suppressions can be added if needed in the future. BUG=pdfium:242,pdfium:260 Review-Url: https://codereview.chromium.org/2360743002
2016-09-21Make the I in IFormFiller explicitdsinclair
Typically the I prefix means Interface, except for CFFL_IFormFiller where it means Interactive. Rename CFFL_IFormFiller to CFFL_InteractiveFormFiller to make the meaning explicit. Review-Url: https://codereview.chromium.org/2357203003
2016-09-21Set up isolate in CFXJS_Engine's constructorweili
CFXJS_Engine class should always be constructed with an isolate, except for its subclasses which may need to create an isolate by themselves. Move SetIsolate() function to be protected so that only subclasses can access it. Review-Url: https://codereview.chromium.org/2354353002
2016-09-21Fix leaks related to the usage of JSE runtime dataweili
Per isolate runtime data should be deleted when the associated isolate's destructed. Also, the internal of per isolate runtime data is obscure to the JS engine. So XFA or this class itself has to be in charge of the memory management. Use smart pointer for it so that the resource could be released properly. BUG=pdfium:242 Review-Url: https://codereview.chromium.org/2354923003
2016-09-21Rename m_pApp to m_pEnvdsinclair
The m_pApp variable holds a CPDFSDK_Environment. This Cl renames the variable to be m_pEnv so as not to confuse with the various App classes that exist. Review-Url: https://codereview.chromium.org/2357293002

2016-09-20Make CPDF_Array not do indirect object creation.tsepez
We remove the indirect object holder argument and check that call sites pass ownable objects, adding a reference in one place that always was passing an indirect object. Also check that the invariant isn't violated, we need to fail here in the wild and investigate -- these are existing UAFs. Review-Url: https://codereview.chromium.org/2355083002
2016-09-20CPDF_Document friend cleanupdsinclair

BUG=79367, 48791 The fonts was not cleared after unloading pages. Test pdf: http://www.nasa.gov/pdf/750614main_NASA_FY_2014_Budget_Estimates-508.pdf For this file, we have ~5 fonts per page, which equal ~1 Mb per page. In this PDF we have 670 pages, as result after slow scrolling(reading) full document we have ~600 Mb fonts data in memory. Memory usage of PDF Plugin: before this CL: ~660 Mb after this CL: ~100 Mb This is last part of reverted CL: Original CL: https://codereview.chromium.org/2158023002 Revert reason: BUG=647612 Fix bug CL: https://codereview.chromium.org/2350193003 Previous CL: https://codereview.chromium.org/2350243002 Review-Url: https://codereview.chromium.org/2351193002
2016-09-20Assert that dictionary can own the objects it is given.tsepez
Upon indirect object holder destruction, all indirect objects are destroyed -- currently by order of increasing object number -- but ideally without ordering constraints. So currently, we can get away with a dictionary pointing directly at an indirect object with a higher number. It gets destroyed first, invoking Release() on its subordinates, which skips destroying them if they are indirect objects. But we don't want to rely on this artifact of destruction order. Should it happen to be reversed, the dictionary would invoke Release() on freed memory. Interestingly, CPDF_Array skirts the issue by replacing any indirect objects it is given with references. Not clear whether we should do the same thing for dictionaries, or remove it from arrays. The technique certainly complicates understanding ownership. The one violation found is in the unittest that broke the previous CL which tried to use unique_ptrs in indirect object holder. Review-Url: https://codereview.chromium.org/2353093002
2016-09-20Refactor CFX_FontCache to have only one in GE Module.art-snake

If the --if-needed argument is passed to the clang update script then we depend on GYP_DEFINES to be set in order to update clang. We no longer define GYP_DEFINES so we fail to update clang (or checkout clang). BUG=chromium:647380 Review-Url: https://codereview.chromium.org/2350093002
2016-09-19Clean up CPDF_Stream.tsepez
Replace the CPDF_Stream(nullptr, 0, nullptr) pattern with a default ctor. Remove unused parameters from CPDF_Stream::SetData(). Both are always passed as FALSE. CPDF_Stream declared its own m_GenNum, which shadowed the one in CPDF_Object. It was used only to distinguish file/memory streams, so add a bool explicitly for this purpose. Remove the union, it would be sad if we confused user data with a C++ object with virtual function calls. Use unique_ptrs with appropriate deleters to manage memory.
