2017-08-30Rebuild CFDE_TextEditEngine.Dan Sinclair
This CL rebuilds the text edit engine in a simpler fashion. Instead of depending on multiple pages, paragraphs and buffer fields there is a single text edit engine which contains a gap buffer. This makes the code easier to understand and follow.

2017-08-28Add a global font loader in XFA testsDan Sinclair
This CL creates a global font loader for use in XFA tests. This is needed because the CFGAS_FontMangaer takes a linearly increasing amount of time to load fonts each time it's loaded. This can get excessively slow for test suites which run a lot of tests.

2017-08-23Convert string Find methods to return an OptionalRyan Harrison
The Find and ReverseFind methods for WideString, WideStringC, ByteString, and ByteStringC have been converted from returning a raw FX_STRSIZE, to returning Optional<FX_STRSIZE>, so that success/failure can be indicated without using FX_STRNPOS. This allows for removing FX_STRNPOS and by association makes the conversion of FX_STRSIZE to size_t easier, since it forces checking the return value of Find to be explictly done as well as taking the error value out of the range of FX_STRSIZE. New Contains methods have been added for cases where the success or failure is all the call site to Find cared about, and the actual position was ignored.

2017-08-02Rewrite how string Insert() methods handle out of bound indicesRyan Harrison
The existing behaviour was to clamp the provided index to the valid bounds. This would lead to programming errors being hidden, since inserting would still do something even if the index calculation was wrong. The behaviour of these methods has been changed to instead early return when this occurs, returning the old length value. The caller can check if the call to Insert actually did anything by comparing the returned value to the length before calling insert. All of the existing calls to Insert have been tested by running all of the tests with asserts in the Insert method to check the index is in bounds. Additionally the call sites have been manually inspected. The majority of them are of the form Insert(0, foo) and the rest tend to be in a loop advancing from 0 to length. Convenience methods InsertAtFront/InsertAtBack have been added to handle calling Insert when the intent is for the character to be added to the beginning or end of the string. Existing call sites to Insert that do this have been converted. This work was originally being performed to check if there would be any issues in these methods with making FX_STRSIZE unsigned.

2017-08-01Replace raw value for constant error value in string operationsRyan Harrison
Currently Find() and other methods that return a FX_STRSIZE return -1 to indicate error/failure. This means that there is a lot of magic numbers and magic checks floating around. The standard library for similar operations uses a npos constant. This CL implements FX_STRNPOS, and replaces usages of magic number checking. It also does some type cleanup along the way where it was obvious that FX_STRSIZE should be being used. Removing the magic numbers should make eventually changing FX_STRSIZE to be unsigned easier in the future.

2017-07-28Convert calls to Mid() to Left() or Right() if possibleRyan Harrison
The various string/byte classes support Mid(), Left(), and Right() for extracting substrings. Mid() can handle all possible cases, but Left() and Right() are useful for common cases and more explicit about what is going on. Calls like Mid(offset, length - offset) can be converted to Right(length - offset). Calls like Mid(0, length) can be converted to Left(length). If the substring being extracted does not extend all the way to one of the edges of the string, then Mid() still needs to be used.

CFGAS_GEFonts are ref counted, and its a good thing since they are managed by at least three different font managers: CFGAS_FontMgr, CXFA_PDFFontMgr, and CXFA_FontMgr. None of these have a clear claim to ownership of the CFGAS_GEFont. CFGAS_GEFont has back-pointers to two of these, CFGAS_FontMgr, and CXFA_PDFFontMgr, and they could each outlive the other. Thus the font needs to watch for destruction of either of its managers, so as to stop using it after its gone.

2017-05-16Introduce CFX_UnownedPtr to detect lifetime inversion issues.Tom Sepez
There are places where an object "child" has a raw pointer back to object "owner" with the understanding that owner will always outlive child. Violating this constraint can lead to use after free, but this requires finding two paths: one that frees the objects in the wrong order, and one that uses the object after the free. The purpose of this patch is to detect the constraint violation even when the second path is not hit. We create a template that is used in place of TYPE*. It's dtor, when a memory tool is present, goes out and probes the first byte of the object to which it points. Used in "child", this allows the memory tool to prove that the "owner" is still alive at the time the child is destroyed, and hence the constraint is never violated.

2017-04-18Subclass the stream implementations from CFGAS_StreamDan Sinclair
Rename CFGAS_TextStream to CFGAS_Stream. CFGAS_Stream is converted to a base class instead of accepting an IFGAS_StreamImp. Things which inherted from IFGAS_StreamImp now inherit from CFGAS_Stream. The stream type inputs are changed to IFX_SeekableStream so that they can accept the same type (IFX_SeekableStream is an IFX_SeekableWriteStream and an IFX_SeekableReadStream). This way the storage can be shared in the base class.
