2018-02-23Setup testing XFA using .in fileschromium/3355chromium/3354Ryan Harrison
This adds a number of {{}} style tags to the .in format that allow the fix-up script to inject XFA related boilerplate into the PDF, instead of having the .in file replicate this. A simple example XFA .in file, called xfa_example.in has been added as a template for future files to follow. Finally a run_xfa_tests.py has been added for executing all of the tests in testing/resources/xfa, which from what I can tell are not executed any other way. All of the existing PDFs in that directory are currently suppressed.

This CL simplifies the if expression parsing. The elseif construct has been split into its own list of IfExpressions and no longer gets stuffed into the elseExpression. A loop was added into the output methods for the elseif expressions, which also means we can go from having: if () { } else { if () { } else { } } to if () { } else if () { } else { } Which is a bit nicer.

2018-02-16Correct mapping text to characters for characters missing from fontRyan Harrison
When parsing text streams there is an internal character list that is generated of all the characters in the stream. Additionally a text string is generated that is exposed via the public API. This string will have all of the printing, i.e. non-control characters, in it. For characters that are not in the font of the stream the unicode, but printable, the character 0xFFFE is used in the text to indicate a missing character. This a non-printing character to indicate non-unicode. The internal character list gets a Unicode value 0x0 when there isn't a glyph in the font for it and the original character code is preserved. This means that when generating the mapping between text string and character list, the code is mistakenly thinking that the unprintable character was not present in the text string. I have changed the check in the mapping generation code to correctly account for this. Additional investigation is needed to determine if inserting 0xFFFE in the text is the correct behaviour. This patch resolves an issue where the find highlights in Chrome for a PDF would be offset when there are unprintable characters in a stream.

2018-02-15Revert "Actually enable -Wimplicit-fallthrough for pdfium."dsinclair
This reverts commit 60027a205953e95b230f289118448b55f12f9a94. Reason for revert: This will break the fuzzer build in Chromium because the XFA side is still broken. I think we need to roll the build/ directory or clang to get the new flag and then build locally before re-enabling? Or, build with pdf_enable_xfa = true in a chrome checkout.

2018-02-15Add limit to number of formcalc expressionsDan Sinclair
Currently it's possible to create a formcalc script which creates a large number of expressions. This will eventually cause stack exhaustion as we try to allocate the needed expression objects. This CL limits the number of parsed expressions in the PostExpression section in order to keep from failing due to stack overflow.
