2017-04-17Fix buffer management issues in CFX_SAXReader.Tom Sepez
Re-write to use std::vectors rather than self-managed buffers. Includes test case that breaks before patch. Formerly, we had two independent buffers whose position were tracked by the same variable, assuming that only one was being written to at a given time. This is a bad idea because it's easy to forget to zero the index when switching buffers, and start indexing into one using previously computed offsets from the other. Additionally, there were cases where the location of a partial entity wasn't discarded when switching states thus clearing the buffer tracking said entity.

2017-04-07Remove the ICC transform where it is never initialized.Nicolas Pena
- All callers of CFX_DIBitmap methods use nullptr as the ICC Transform. - The CFX_ScanlineCompositor is always initialized with a null ICC transform. Many of its methods call TranslateScanline from the ICC module. This method casts just uses ((CLcmsCmm*)pTransform)->m_hTransform, and this should not be done when pTransform is nullptr.

2017-04-07Remove the "old way" of performing FlateUncompress.Tom Sepez
Repeated looping over Realloc() with a linearly increasing buffer size is going to be O(N^2) which is why it was limited to small cases. But it's wrong to do it anyways, and it kicks out a lurking issue in PartitionAlloc as it turns out. See https://crbug.com/709271, but this doesn't actually fix that issue, it just avoids it.
