2016-10-03Assert that only 0-numbered objects are Released()tsepez
This condition holds because numbered objects are brute-force deleted by the indirect object holder, rather than being released. Be careful about recursive deletion, check before advancing, since we no longer count on Release() doing this for us. Fix a few tests where the test was violating ownership rules. This should be the last step before completely removing Release() in favor of direct delete everywhere. Review-Url: https://codereview.chromium.org/2375343004

2016-08-24Removing CPDF_Parser::CloseParser.chromium/2839dsinclair
Currently the only calls to CloseParser() happend in the destructor or the start*Parse methods. The Start*Parse methods are currently only called on freshly constructed parsers in fpdf_dataavail and fpdfview. This CL removes the CloseParser() method and puts the contents in the destructor. We then add an ASSERT that we don't re-enter the parser after it has already completed the parse. Review-Url: https://codereview.chromium.org/2267173005
2016-08-24Flip document and parser ownershipdsinclair
This Cl switches the ownership between the parser and the document. Previously the parser owned the document and we'd jump through hoops during cleanup to delete the right object. This Cl flips the ownership so the document owns the parser and simplifies the cleanup logic where needed. BUG=pdfium:565 Review-Url: https://codereview.chromium.org/2275773003

2016-08-17Move parser pointer to CPDF_Documentdsinclair
The CPDF_IndirectObjectHolder has two subclasses, CPDF_Document and CFDF_Document. The CPDF document requires the parser and the CFDF document does not. This cl moves the parser pointer up to CPDF_Document. Review-Url: https://codereview.chromium.org/2253723002
2016-08-16Rename async to linearized when parsingdsinclair
The parser and document refer to async loading and parsing. The code isn't actually async but loading a linearized PDF. This Cl renames the methods to clarify what the code is doing. The LoadDoc() and LoadLinearizedDoc() methods have been refactored to share a common LoadDocInternal() method. Review-Url: https://codereview.chromium.org/2250163002

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.

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.
