2018-08-08Move ByteString::FromUnicode() to WideString::ToDefANSI()Tom Sepez
Turns out that "FromUnicode" is misleading in that, on linux, it simply removes any characters beyond 0xFF and passes the rest unchanged, so no unicode decoding actually takes place. On Windows, it passes it into the system function specifying FX_CODEPAGE_DefANSI, converting it into the so-called "default ANSI code plane", passing some characters, converting others to '?' and still others to 'A'. Either way, nothing resembling UTF8 comes out of this, so pick a better name. These now immediately look suspicious, so a follow-up CL will see which ones should really be WideString::UTF8Encode() instead. Making this a normal method on a widestring rather than a static method on a bytestring feels more natural; this is parallel to the UTF8Encode and UTF16LE_Encode functions. Add a test that shows these conversions.

2018-06-20Re-work some more c_str() usage.Tom Sepez
Many of these are converting ByteString => c_str => ByteStringView, since the ByteStringView ctor is implicit. This is unfortunate, since that involves a strlen() which the ByteString already knows if we use AsStringView() instead. This changed one test result where we can now return the string "\0" instead of "" -- since strlen no longer eats the NUL. This seems consistent, say, with String.fromCharCode().

Removed some unused assignments and now unused variables. Also rewrote a for loop so that its secondary condition is now in the control block. The static analyzer was claiming it was possible for a division by 0, though following the control path it was claiming, I am pretty sure it should have exited early. This reorganizing of the code makes it a bit more readable and eliminates the div by 0 warning from the static analyzer. Issues found with Clang Static Analyzer.

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.
