2017-08-09Add a build target and a proper export header for shared library builds.Felix Kauselmann
This CL adds support for Chromium's component build feature to pdfium. The export header stub in fpdfview.h is expanded to match Chromium's export mechanisms and patterns (fixes pdfium:825). A component/shared library build can be triggered by adding is_component_build = true as a gn argument. Please note that setting this will also affect some of pdfiums dependencies like v8, which will be build as components too. Additionally, this CL provides a "pdf_source_set" template which dynamically enables the use of "source_set" when building a complete static library or a shared library to reduce build time. When testing this it is recommended to only build the pdfium target as most of pdfiums test rely on non-public functions which aren't exported by the shared library.

With these factors it is difficult to predict what will be the final file. To reduce volatility use only one method that works in all cases mentioned. This method is parse then serialize.

2017-08-02Remove support for out of bounds params in DeleteRyan Harrison
The existing implementation of Delete on the string classes handles some cases where the range being deleted is out of bounds by clipping it to the valid range. This behaviour can lead to programming problems in the calling code being masked by the fact the Delete method still does something. The new version of these methods does an early return if the parameters are invalid. This change also effectively removes support for negative string sizes from the Delete method, so converting FX_STRSIZE to be unsigned will be easier.

2017-08-02Add CFFL_TextField class.chromium/3175Lei Zhang
This class implements common code used by several CFFL_FormFiller sub-classes. Make those sub-classes inherit from CFFL_TextField, instead of inheriting from CFFL_FormFiller directly and then implementing the same functionality multiple times.

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.
