2015-10-09Pass IJS_Runtime, not IJS_Context, to native object constructors.Tom Sepez
This better separates the two IJS_ classes, with the IJS_Context taking on its proper role of describing an event. There's no need for the event details for object creation, so this gets much cleaner. Move some JS error reporting code from CJS_Context to CJS_Runtime. Make InitInstance() and ExitInstance() voids, they always return TRUE and we never check the result anyways. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1389163007 .
2015-10-09Allow compiling PDFium without V8.Tom Sepez
Original patch from issue 1391843004 at patchset 1 (http://crrev.com/1391843004#ps1) Introduce a pdf_enable_v8 GYP variable, which controls a corresponding PDF_ENABLE_V8 #define, and bring in the real JS library when set. Otherwise, link against a stub JS runtime. BUG=pdfium:211 R=dml@google.com, jochen@chromium.org, thestig@chromium.org Review URL: https://codereview.chromium.org/1395733006 .
2015-10-08Wean CJS_Value off of v8::Isolate.Tom Sepez
CJS_Values should belong to CJS_Runtimes so that we may eventually cram much of the v8 dependencies down into fxjs. This is a first step; the remaining split in this code between isolate and CJS_Runtime goes away when fxjs provides a CFXJS_Runtime object, and the CJS_Runtime is-a/has-a CFXJS_Runtime. But that can't happen until this is resolved. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1394103002 .
2015-10-07Rename IFXJS_Runtime and IFXJS_Context to IJS_.Tom Sepez
Nothing but sed. FXJS is a layer that makes it easier to define objects in V8, but has no knowledge of PDF-specific native objects. It could in theory be used to implement other sets of native objects. JS is the layer that implements PDF-specific native objects on top of FXJS. Therefore, the classes used to interface to JS should be named using IJS_. IFXJS_ is reserved for someday adding better API for FXJS iteslf.

2015-10-06Store object definition ID in each js_class.Tom Sepez
Avoids doing a lookup via FXJS_V8 for something already known in CJS layer. Also: Consolidate repeated code in JS macros. Remove knowledge that Document is global from FXJS layer R=thestig@chromium.org Review URL: https://codereview.chromium.org/1382263002 .

2015-10-06Make the vast majority of JS headers private to src/javascript.Tom Sepez
The fpdfsdk/include/javascript/IJavascript.h is the sole API. This required moving a creaton method to it from JS_Runtime. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1389783002 .
2015-10-05Remove JavaScript.hTom Sepez
It merely includes a bunch of other .h files which are handled better since we fixed IWYU. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1385983002 .

2015-10-02Pass v8::Isolate to PDFium at init time.Tom Sepez
Move the external isolate and embedder slot from the IPDF_JSPlatforms struct supplied at the FPDFDOC_InitFormFillEnvironment() call time to arguments to the FPDF_InitLibraryWithConfig() call. This has several benefits: -- Avoids the crash that could happen if multiple FPDFDOC_InitFormFillEnvironmen() calls should happen to be made by an embedder with different slot values. -- Down the road, for XFA, there may be XFA but no FormFill environment. We support both forms for the time being, until the chrome side catches up, at which point we will deprecate the old way.

Right now we're freeing per-isolate data everytime a document is destroyed even though it may be in use by other documents. For now we leak the per-isolate data until crbug.com/531339 is fixed.

Follow-up from https://codereview.chromium.org/1366053003/ - use kPerIsolateDataIndex rather than magic constant 1. - make a helper function for common code in JS_Define.h - remove dead prototypes missed in earlier CL. - fxjs_v8 can't include generic fpdfsdk includes (layering).

2015-09-25Revert "Revert "Merge to master: contention over isolate data slots""Tom Sepez
This reverts commit 3b4382a847b5a7439a3107512dbe54c317108579. The difference between this CL and the one that failed is fxjs_v8.cpp:271. In master, we pass the runtime information as: v8::isolate -> v8::Context -> FXJS Runtime, but in XFA: V8::Isolate -> PerIsolate struct -> FXJS Runtime. The master way is more correct, in that FXJS_Runtime is 1:1 with v8 contexts and many:1 (in theory) with isolates. It looks like the XFA branch missed a patch along the way. I'll do that next. Having made this change, the only data in the per-isolate struct will be the ptr array (on master); it will also include the XFA context (on XFA). I've kept the struct on master for the sake of similarity. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1365733003 .
2015-09-22Revert "Merge to master: contention over isolate data slots"Tom Sepez
Reason for revert: embeddertests failed. This reverts commit 70bc04b16646c92f221c5aa56831b01d6ec7c1ca. TBR=thestig@chromium.org Review URL: https://codereview.chromium.org/1358263004 .
2015-09-22Merge to master: contention over isolate data slotsTom Sepez
Work on this was first performed on the XFA branch, since it has additional requirements (FXJSE layer) that needed to be accomodated by the solution.

2015-09-22Use std::set<> to track active event handlers.Tom Sepez

2015-09-16Ensure functions in FXJS_V8 are prefixed by FXJS_.Tom Sepez
Currently, its hard to tell which functions come from the JS_ layer at fpdfsdk/include/javascript vs. which functions come from the FXJS_V8 layer at fpdfsdk/include/jsapi. Until we take up the task of using namespaces, at least make the prefix consistent. Move objects out of FXJS_V8 that are really part of JS_.

2015-09-15Refactor fxjs_v8 and add embeddertests for it.Tom Sepez
This forces the layer defined by fxjs_v8.h to be (more) self-contained, so that it can be tested apart from the CJS_* objects (in fpdfsdk/{src,include}/javascript. This implies the array buffer allocator must be part of fxjs_v8. One wrinkle is that we'd like to be able to test an isolate upon which no native objects have been added, so some initialization that would have occurred as part of object definition must be made explicit.

2015-09-14Get CJS_RuntimeFactory out of the CJS_GlobalData management business.Tom Sepez
First part of getting rid of CJS_RuntimeFactory. The factory design pattern isn't appropriate here since we only ever make one kind of object. CJS_GlobalData is now perfectly capable of managing itself through internal ref counts. I'm philosophically opposed to keeping ref-counts outside the object (do you hear me std::shared_ptr, you're bad!) R=thestig@chromium.org Review URL: https://codereview.chromium.org/1338993005 .

2015-09-10Remove some abstractions in fxjs_v8.h.Tom Sepez
It's too hard to keep mapping between v8 and fx abstractions; the lack of transparency prevents those skilled in v8 only from working on this code. Apparently, the original intention was to confine v8 types to fpdfsdk/{include,src}/jsapi, but fpdfsdk/{include,src}/javascript is already well-polluted with v8 types. Also remove no-op JS_SetThisObj(). Also remove unused ParserParams() [noticed because it was incorrectly passing handles as pointers]. Also remove cast operator from CJS_Runtime and call GetIsolate() explicitly. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1332973002 .

2015-09-10Resolve bad cast to CJS_EventHandlerfoxit
At line 2026 in pdfsdk/src/javascript/PublicMethods.cpp, the writer wants to perform type cast like line 2027 but he made a mistake to make type conversion on m_pValue. Even at line 2027, it's redundant to make type conversion. The returned type of pContext->GetEventHandler() is CJS_EventHandler*.

2015-09-09Fix heap use after free in CPDFSDK_Annot::GetPDFAnnot.Tom Sepez

2015-09-01Remove IPDFSDK_AnnotHandler interface.Tom Sepez
It's pointless to have an abstract interface and its only concrete implementation defined in the same header. We can de-virtualize along the way and get a small savings. Rename CPDFSDK_BFAnnotHandler along the way, since its the only kind of AnnotHandler, and I can't imagine what BF stands for.
