2018-08-07Add test for {Byte,Wide}String Operator+().Tom Sepez
Precursor to converting some Format() operations to simple string addition. Change-Id: I3a159f5ac548ea14586d87e7d56d1ec288898b0d Reviewed-on: https://pdfium-review.googlesource.com/39590 Reviewed-by: Lei Zhang <thestig@chromium.org> Commit-Queue: Tom Sepez <tsepez@chromium.org>
2018-08-07Combine redundant CJBig2_Image code.Tom Sepez
Once upon a time, someone cut-n-pasted ~300 lines of code to avoid creating a default rectangle and to save a couple of additions. Then one path got one set of fixes (safe ints) and the other path got a second set of fixes (source bounds checks). Re-unify, picking up all the fixes, since they are identical otherwise.

2018-08-07Speculative fix for null deref above ThrowNoDefaultPropertyExceptionTom Sepez
Avoid possibility of an unterminated string or nullptr by avoiding stringviews, since the non-view classes copy and always provide a suitable result. Always use %ls and widestrings in wprintf() variants, since that combination is consistent across our platforms (%s, %S, etc. have idiosyncracies).

2018-08-03Make CFX_XMLParser less permissiveRyan Harrison
Currently the parser will accept arbitrary garbage before the first element begins. This is causing issues with ClusterFuzz since it generates a lot of trash inputs which take a long time to parse inspite of being invalid. This CL adds in a check of how deep the parse is when dealing with text, and if it is at the top level scope, then only accept the beginning of the root node.
