Needed to fix the failed pdfium_unittests on windows. Ironically, I created these constants so I wouldn't mix up size_t's and off_t's in these tests, but I didn't apply them consistently. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1036743005

2015-03-19Fix subtle issues in opj_skip_from_memory and add unit tests.Tom Sepez
Follow on to https://codereview.chromium.org/990683002/. This more closely mimics what fseek() actually does, so as to avoid subtle bugs down the road. Move the DecodeData struct into a header so the test can use it, and provide a constructor for it. Along the way, I added include guards, removed the p_ prefix from some non-pointer vars, fixed some IWYU, and resolved some signed/unsigned comparison warnings with careful casting.

space is used" This reverts commit 5a0e504d53195892458d819e52c62bea0c710bd5. Original review URL https://codereview.chromium.org/1009513003 Reason for revert: New "corpus" tests show that this is no longer rendering some images.

2015-03-16Fix a problem that JP2 image is not displayed because index color space is usedJUN FANG
There are two issues in this bug. One is that JP2 image is not displayed because it aborts loading Jpx bitmap when the number of components in color space is different with that one in JPX images. I found that the number of components in color space isn't updated after it's initialized. For index color space, the component shall inherit from its base color space. The second issue is that displayed color is not correct after I fixed the first issue. The root cause is that sRGB is used in JPX image, it doesn't need to map from index to RGB again.

2015-03-16Fix a bug that JPX images can't be shownJUN FANG
In the process of opj_end_decompress, it will return fail when the end of coding stream is reached. However it returns true in the same scenario implemented in openJPEG. So the final solution is from openJPEG. Return true when the end of coding stream is reached. BUG=452671 R=tsepez@chromium.org Review URL: https://codereview.chromium.org/990683002

2015-03-12Kill CFX_GrowOnlyPool.Tom Sepez
It's unused, and when the time comes, we'll want to put pdfium onto a hardened allocator like partitionAlloc anyways. Along the way, merge adjacent #ifdef __cplusplus blocks, remove a pointless check for __cplusplus inside a .cpp file, and remove a redundant cast.

2015-03-06Make conversions for CPDF_Link explicit.Tom Sepez
Precursor to taking a second shot at cleaning up the FPDF_* APIs. A FPDF_LINK is a CPDF_Dictionary, and a CPDF_Link is a structure holding a FPDF_LINK. This goes against the convention that FPDF_ types get cast to CPDF_* types, so we want to make it clear where objects are getting constructed.

Precursor to taking a second shot at cleaning up the FPDF_* APIs. A FPDF_Dest is a CPDF_Array, and a CPDF_Dest is a structure holding a FPDF_Dest.

Precursor to taking a second shot at cleaning up the FPDF_* APIs. A FPDF_Action is a CPDF_Dictionary, and a CPDF_Action is a structure holding a FPDF_Action. This goes against the convention that FPDF_ types get cast to CPDF_* types, so we want to make it clear where objects are getting constructed, etc. Also tidy fpdf_actionhandler.cpp because it bugs me.

2015-02-05Fix segv in CPDF_DataAvail::CheckRoot() when /Root object is a string.Tom Sepez
Handles the case of this malformed PDF without crashing. Note that to get a reproducible test case, a small fix is applied to our .py script which results in some whitespace/numbering difs across the resources (down the road, we ought to generate them on the fly in an intermediate directory).

2015-02-05Add namespace and-re-arrange PDFium's local copy of chromium /base.Tom Sepez
Any projects DEPS'd into chromium and requiring a /base subset should have a local copy of that subset in a separate namespace. This will avoid future naming conflicts. Re-arrange the directory structure to better identify what came from chromium's base, and to make drop-in replacement easier for files that contain hard-coded "base/" in their #include directives.

2015-01-31Fix heap buffer overflow in CPDF_SampledFunc::v_CallJUN FANG
This issue was caused by integer overflow in CPDF_SampledFunc::v_Call. The root cause of this issue is that the content in the test pdf file was damaged.

2015-01-29Fix infinite recursion in CPDF_RenderStatus::RenderSingleObject().Tom Sepez
Introduce a local static to track the recursion depth, thereby removing the burden for callers to track and pass a level parameter correctly through all call paths.

2015-01-26Fix infinite recursion in CPDF_Parser::ParseIndirectObjectAt().Tom Sepez
A suitably corrupted file can cause the parser(s) to repeatedly re-read sections of the file at increasing parser recursion depth until the stack is exhausted. There is supposed to be a check for this based upon the parser "level", but not all call paths pass or update the level as required. Much as I hate per-class statics, this introduces one to track the depth so that the check is enforced no matter how screwy the call path might be that leads the parser to re-enter itself. This is more palatable than trying to find all these paths and fix them. We know this is OK since there is only one thread in here modifying the static.

2015-01-22Use IPDF_DataAvail interface to hide CPDF_DataAvail.Tom Sepez
Currently, no callers go through the Interface, which makes having a separate interface class kind of pointless. After converting callers away from using the CPDF_DataAvail concrete class, it can be moved from the header to the .cpp file.

This is done by explicitly adding a virtual dtor to interface classes, since the cost is small given that there are already virtual functions.

pdfium builds on Win32 have about 85 warnings (250 in the XFA branch, totaling over 480 lines!), mostly from four lines in a header file and a warning that should be disabled. This change resolves all but two of them and turns on warning-as-errors. Bugs have been filed for the two remaining warnings: https://code.google.com/p/pdfium/issues/detail?id=100 the 64-bit warnings: https://code.google.com/p/pdfium/issues/detail?id=101 and the Linux warnings: https://code.google.com/p/pdfium/issues/detail?id=102 The fix to the double->float truncation bugs will also improve code-generation.
