2017-11-01Split JS code out of CXFA_Node.Dan Sinclair
This CL moves JS code out of CXFA_Node and places it into fxjs/cjx_node. The CXFA_Node then has a CJX_Node as a member and, currently, proxies JS calls to the CJX_Node member.

2017-11-01Move some XFA JS code into fxjs/Dan Sinclair
This CL renames cxfa_scriptcontext to cfxjse_engine and cxfa_fm2jscontext to cfxjse_formcalc_context. From reading the code, the script context appears to handle the v8 setup and object code. The formcalc context code is related to handling the JS code generated from the transpiler. I, think, these new names make the intended usage clearer. They also move the code into fxjs/ to keep along side the rest of the JS code.

2017-09-06Convert FX_STRSIZE int->size_tRyan Harrison
Change the underlying type for FX_STRSIZE to size_t from int. This will make the value unsigned and thus all values in the range of the type will be valid. This allows for the final remove of negative length strings, but also introduces a some casting and functional errors, since many parts of the code base assume that FX_STRSIZE is int or another signed type.

2017-09-01Cleanup usages of Mid(foo, 1), Right(1), and Left(1)chromium/3203Ryan Harrison
Mid(foo, 1) is equivalent to [foo], if all you want is the character. Similarly Left(1) is [0]. It is faster also, since it does not need to create intermediate strings. Right(1) is a touch more tricky, since it requires something like GetLength() ? [GetLength() - 1] : 0;. A new method, Last() has been added to perform this character extraction. Multiple call sites have been updated to use more efficient/simpler syntax. There are a number of call sites that use on these patterns, but based on the surrounding context we actually need/want a string, so they have not been modified.

2017-08-30Convert int* references to FX_STRSIZERyan Harrison
Through out the code base there are numerous places where variables are declared using a signed integer type when interacting with the string classes, since they assume that FX_STRSIZE is 'int'. As part of changing the underling type of FX_STRSIZE to be unsigned, these locations are being changed to use FX_STRSIZE. This is necessary as part of converting the type, but has been broken off into a separate CL, since it should be low risk. Some related cleanups that are low risk are included as part of this CL.

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.

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.

The old behaviour of calculating the length for the user if -1 is passed in for the count has been removed.

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.
