2017-06-29Cleanup call expression handling in fm2jsRyan Harrison
Remove handling of arbitrary function calls, and only allow supported function calls. Issues with the lexer being overly permissive led to large blobs of javascript being dropped into the output. Specifically driver code was assuming that anything marked as a function would just be an identifier that could be inserted into the javascript, but the lexer marks things like ()()() as a function, which would lead to the following JS being inserted as an identifier. This change is intended to be a patch for the specific issue that was being seen from the fuzzer test, and further work will be needed to make the lexer more strict. BUG=724913 TEST=Ran fuzzer test case. Ran unittests,embeddertests,corpustests.

2017-06-28XFA: Add test to show Oneof() works correctly.Lei Zhang
The new embedder test shows Oneof() works, whereas the corpus test does not. It turns out the corpus test was bad, and trying to fix it exposed a different bug. So roll DEPS for the testing corpus anyway to get improved tests, but keep the suppression for now.

2017-06-28Set default graphics before generating page contentsNicolas Pena
In this CL, the content generator sets some default graphics states before processing the page objects. In particular, a default ExtGState is now set before processing, and the last CTM is now stored right after parsing finishes: the only command to change matrix is ctm, and it concatenates, so inverting requires knowing the current value.

2017-06-22Minor change to AP generation logicJane Liu
Current behavior: Our CPVT_GenerateAP::Generate*AP() functions do not get called as long as the annotation dictionary has an "AP" entry. Problem: We always need the "N" entry in AP dictionary to display an annotation. Even though the spec requires "AP" dictionary to have an "N" entry for normal mode appearance, in case of a malformed pdf with "AP" but without "N" in "AP", we won't be able to display the annotation at all. Fix: Always check if "AP" has "N" entry to decide whether AP needs to be generated. If not, then we still need to generate AP, and add to the AP dictionary under the key "N".

2017-06-20Cleanup tiling and shading patterns in correct orderDan Sinclair
When a Shading is created we have both a ShadingPattern and a ShadingObject. The ShadingPattern is a ref-counted object that is stored in the CPDF_DocPageData. The ShadingObject, when we have a tiling pattern parent, is stored in the CPDF_Form of the tiling pattern. Currently during destruction it is possible for the ShadingPattern to get cleaned up before the ShadingObject which causes the UnownedPtr probe to fire. This CL loops over all patterns and for each Tiling pattern forces the CPDF_Form to get cleared. This then removes the ShadingObject before we remove the ShadingPattern.
