2018-05-31Make XFA pixel tests more stablechromium/3447Ryan Harrison
When generating PDFs using the fixup script and a .in, specify them to to use Ahem.ttf as the text font. Ahem is a font designed to reduce flakiness in pixel tests due to font rendering differences between platforms. Specifically the glyphs in the font are standard size black boxes, so though the specific text content cannot be easily compared, things like layout and high level changes to the content can still be tested. Testing things like specific text changes should be done via an embedder test, where the strings in the elements can be extracted and inspected. The font itself is is CID type 2 font, which is relatively complex to correctly embed in a PDF due to subsetting and other features. Instead of embedding it in the generated PDFs, which was originally attempted, it is being supplied to pdfium_test via the --font-dir flag. This flag overrides where the binary looks for system fonts. This works correctly on Mac and Linux, but not on Windows, which is why that platform remains suppressed.

2018-02-07Handle removed fonts correctly in GetFontByCodePageRyan Harrison
The existing code has a couple of issues that need to be addressed. First it assumes that for a hash, there will be an entry in the map and blindly calls the [] operator and takes the address of the result. If there isn't an entry for the hash then this will cause a crash. This has been converted to a call to find and returning nullptr, which is the fail result, if it cannot find an entry for the hash. The other issue is that it assumed that the first entry in the vector would be a valid pointer. When removing fonts from the vector, RemoveFont, first nulls out entries. Once all of the entries have been removed from a vector on subsequent calls to RemoveFont, then the vector is removed from the map. Thus the first entry in the vector might not be the correct value to return. This has been changed to a linear scan of the vector for a valid pointer.
