2016-09-08Fix memory management errors for font loading and copyingweili
A few issues are fixed: --Change variable |m_bLogic| in CFX_Font to |m_bShallowCopy| to reflect its meaning better; --For a shallow copy of font, we must guarantee that the copied font will not be deleted until the shallow copy is deleted. So need to increase the src font's refcount when copying it; --The stream |m_pOwnedStream| needs to have matched new/delete These errors need to be fixed before we can properly delete all the fonts to address the leaks.

2016-09-08Replace CJS_Runtime::Observer with CFX_Runtime<CJS_Runtime>::Observertsepez
Previously, the observer set a flag which conditionalized a null pointer return. Now, we just clear the pointer. Destruction order matters, so add a method to trigger notifications. Review-Url: https://codereview.chromium.org/2322743002
2016-09-08Switch to ValueOrDiedsinclair
We know the values are always valid at this point, so use ValueOrDie instead of ValueOrDefault. BUG=chromium:637984 Review-Url: https://codereview.chromium.org/2319343003

2016-09-07Verify pattern start values.dsinclair
When calculating the starting x and y for a pattern it is possible to overflow the int value. Use checked math to make sure we don't overflow. BUG=chromium:637984 Review-Url: https://codereview.chromium.org/2317283002
2016-09-07Maybe avoid a copy in CPDF_RenderStatus::SelectClipPathtsepez
Use the shared copy-on-write version instead of the underlying CFX_GraphStateData since it may not always get modified. Review-Url: https://codereview.chromium.org/2316823002
2016-09-06Make CPDF_TextStateData private to CPDF_TextState.chromium/2853tsepez
Review-Url: https://codereview.chromium.org/2313083002
2016-09-06Move CPDF_GraphState to CFX_GraphStatetsepez
The FX layer is spying on its private data, so make the job of ref-counting it live in FX as well, instead of up a layer at pdfapi. Pre-cursor to making this private and passing the graph state itself everywhere. Review-Url: https://codereview.chromium.org/2314223002

2016-09-06Move CFX_Font definition to its own file and clean upnpm
- Rename fx_ge_font.cpp to cfx_font.cpp - Deleted unused CONTRAST_RAMP_STEP in fx_ge_text.cpp - Move CFX_Font definitions and auxiliary methods in fx_ge_text to cfx_font - Remove extern "C", static, and underscore prefixes in new namespace methods in cfx_font.cpp Review-Url: https://codereview.chromium.org/2304493005
2016-09-06Move ShouldGenerateAPForAnnotation check to CPDF_Annot::GenerateAPIfNeededtonikitoo
By doing this, we simplify the code in cpvt_generateap.cpp, and avoid calling CPVT_GenerateAP methods altogether, when it is known that they are bailing out. This is a preparation to fix pdfium bug 585. BUG=pdfium:585 Review-Url: https://codereview.chromium.org/2310873002

Review-Url: https://codereview.chromium.org/2310693002
2016-09-02Make CPDF_ClipPath have a CPDF_ClipPathData rather than inheriting.tsepez
Make Data private to the ClipPath class which manages it transparently for its callers. This prevents the callers from having to remember to make a copy before dirtying the shared data, since the operations that modify state will do this under the covers for us. Review-Url: https://codereview.chromium.org/2301263003
2016-09-02Remove CFX_Matrix::Copy() in favor of assignmenttsepez
The default assignment operator will suffice and allows us to write matrix1 = matrix2; Review-Url: https://codereview.chromium.org/2307953003
2016-09-02Make CPDF_GeneralStateData private.tsepez
All interaction goes through the CPDF_GeneralState, which manages the underlying storage transparently to the callers. Make StateData use a real string and a real matrix rather than C-style arrays. Review-Url: https://codereview.chromium.org/2302683002

2016-09-01Fix leaks due to created popup annotationschromium/2847weili
When we create popup annotations, we also create the dictionary associated with it. For regular annotations, the dictionary associated with an annotation is not owned by annotation, and will be released separately. But our created dictionary is not associated with any other data structure, it would be leaked if not released by the associated annotation. Add a boolean to indicate the ownership to the dictionary, and release the owned dictionary during the destruction of an annotation.

2016-09-01Fix CPDF_CIDFont::GlyphFromCharCode for fonts flagged with PDFFONT_SYMBOLICnpm
UnicodeFromCharCode should be tried even if the font is flagged as PDFFONT_SYMBOLIC. The result should be checked in case it's empty. This fixes some corpus tests that were being incorrectly rendered, as well as the bug below. A deps change will be required before landing this CL.

This one doesn't require an explict Emplace(), as the object seems to get constructed only as a side-effect of making a private copy. Review-Url: https://codereview.chromium.org/2298953002

Get callers out of the copy-before-write business, and let the class manage it instead. Review-Url: https://codereview.chromium.org/2292363002
2016-08-31Use enum class for subtypes of CPDF_Annot.jaepark
Comparing CFX_ByteString for annotation subtypes is inefficient and error-prone. This CL uses enum class to compare annotation subtypes. Also, remove unused IPDFSDK_AnnotHandler::GetType() and FSDK_XFAWIDGET_TYPENAME. Review-Url: https://codereview.chromium.org/2295953002
2016-08-31Free the GifPlainText object when complete.dsinclair
We allocate the GifPlainText object on line ~685 inside GIF_D_STATUS_EXT_PTE. We cleanup the internal pointers in the gif_destroy_decompress() but we failed to cleanup the pointer itself. This CL frees the allocated pointer once the data is cleaned up. BUG=chromium:638499 Review-Url: https://codereview.chromium.org/2291143003

2016-08-30Guard against overflow when calculating font weight.dsinclair
This CL uses the safe math libraries when calculating the font weight from the StemV value as very large values for StemV can cause the signed int to overflow. BUG=chromium:641418 Review-Url: https://codereview.chromium.org/2293633002
2016-08-30More better const-ness in CFX_CountRef<>tsepez
There are a couple of places where code is calling GetObject() that should be calling GetPrivateCopy(), but works because the value may not be shared at the time. This just makes it safer. Review-Url: https://codereview.chromium.org/2290863002
2016-08-29Display content of the annotation when mouse hover.jaepark
Each annotation has its contents, and users should be able to see the contents. In this patch, PDFium creates a Popup annotation for each annotation and stores the author and the content. When a user mouse hover on the annotation, PDFium draws the corresponding Popup annotation and displays the content. Also, roll DEPS for testing/corpus to 5867fa6. BUG=62625 Review-Url: https://codereview.chromium.org/2273893002
2016-08-29Skip the channel if there is no data.dsinclair
The JPX decoder needs to verify there is data associated with an image channel before access. This was already done in one side of the if() but seems to be missing from the other. This Cl updates the loop to check the existance of channel data and to continue iteration if none found. BUG=chromium:637232 Review-Url: https://codereview.chromium.org/2291813002

2016-08-29Verify element exists before accessing.dsinclair
Currently when the parser utility classes are outputting to a text buffer we do not verify that an element from an array exists before accessing. We can have null items in arrays (and dictionaries but the dictionary case is already handled). This Cl updates the code to check the element exists before attempting to use the element.

These just invoked exaclty the same methodes in the underlying xxxData class, which we can now do with just a ->() Move some methods to the xxxData class, where they belong.
