2015-10-27Type check the m_pShadingObj before assuming it's a stream.Dan Sinclair
The m_pShadingObj can be a stream or a dictionary depending on how it's used. This CL adds some simple type checking to make sure that the type of the object matches what we expect. BUG=chromium:547706 R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1421973004 .
2015-10-26Revert "Make m_pShadingObj a CPDF_Stream instead of CPDF_Object."Dan Sinclair
There appear to be a bunch of corpus tests which fail with this change such as FAILURE: shading1.pdf This reverts commit 85361b227ad6786d2aeef8409b79a8d077a26ee9. Make m_pShadingObj a CPDF_Stream instead of CPDF_Object. This object is required to be a stream and was being converted as such. With the new type checking this caused us to pass a nullptr where previously we'd have, incorrectly, cast a CPDF_Dictionary to a CPDF_Stream. This CL changes the m_pShadingObj to always be a CPDF_Stream. Then, we never go down the bad code path because we check if m_pShadingObj is nullptr earlier and bail out. BUG=chromium:547706 TBR=tsepez@chromium.org Review URL: https://codereview.chromium.org/1414283003 .

2015-09-29Fix blank page issue caused by too strict correction on bpcchromium/2523Jun Fang
For bit per component (bpc), PDF spec mentions that a RunLengthDecode or DCTDecode filter shall always deliver 8-bit samples. However, some PDF files don't follow this rule. We can find that filter is RunLengthDecode but bpc is 1 in the provided test file. In this case, pdfium will correct bpc to 8 but the actual bpc is 1. It causes a failure because the data is much more than the expected. To handle this case, pdfium doesn't correct bpc to 8 when the original bpc is 1.

2015-09-28Fix test diff caused by v8 version updateTom Sepez
Also changes DEPS to specify a specific v8 version, this will require us to manually update this version from time to time, but also solves a longstanding problem where going back to an older version (say for bisecting) wouldn't always work.

2015-09-25Revert "Fix the issue that pdfium swallows 'fi' or 'ff' in some pdf files"Jun Fang
This reverts commit 9bd18183ba8210c91d71c3060146235750a4c71c.
2015-09-25Fix the issue that pdfium swallows 'fi' or 'ff' in some pdf filesJun Fang
Pdfium swallows 'fi' or 'ff' in some tested files because it doesn't load the embedded font file correctly. The root cause is that there is incorrect keyword like 'ngendstream' in the stream of the embedded font file. Pdfium tries to find another correct keyword but uses wrong offset rather than accumulated offset.

2015-06-30Redo range check in CPDF_SampledFunc::v_Call().Tom Sepez
The current |bitpos1| calculation protects the passed argument to _GetBits32(): |bitpos.ValueOrDie() + j * m_nBitsPerSample|, but doesn't account for adding in the sample length in that routine. Also bound bits per sample to something reasonable to avoid undefined behaviour on the shift to compute the max value.

2015-06-02Automated test case for 487928.Tom Sepez
Reproducing this bug requires the embedder to fire timers, something the single-pass pdfium-test binary doesn't do properly at the present. So we modify the embedder test delegate to allow the immediate triggering of the same. Perform some cleanup along the way by removing EmbedderTestDefaultDelegate -- it buys us nothing over the the no-op one. And, of course, v8 initialization is busted again, and we need v8 here. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1153213004
2015-04-27SEGV in CFX_BaseSegmentedArray::Iterate() when CS has malformed dictionary.Tom Sepez
Failure to check document-controlled value before using it. BUG=481363 R=palmer@chromium.org, thestig@chromium.org Review URL: https://codereview.chromium.org/1110653002
2015-04-23Remove unused nParamNum values from JS method tables.Tom Sepez
The code to validate the number of parameters happens inside each particular method, rather than prior to method dispatch. As such, there's no point in having this number take up space in the table. Add some test to cover at least some of the per-method validations, and update error messages to be more useful. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1084183008
2015-04-03Add embedder test comparing with the last patch.JUN FANG
When there is a wrong keyword like '??ze' in the dictionary of the trailer, PDFium can't recognize it and aborts further parsing. After this change, PDFium continues even it can't get the right size at this moment. It will rebuild the cross reference table later since the size of the table is missing. BUG=459580 R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1055323003
2015-03-17Revert "TEST that the tree goes RED when pixel/javascript tests fail."Tom Sepez

2015-03-02Return error information from pdfium to JS.Tom Sepez
This implements the previously unimplemented JS_Error() function. Along the way: - fix some IWYU when the include order in global.cpp was perturbed. - remove some uses of JS_ErrorString, to increase transparency. - use vp.IsSetting() in place of !vp.IsGetting() for clarity. - specify an error string on several error return paths. - add an error string for writing readonly properties. - rename an error string constant to reflect the actual message. - replace calls to variadic Format() with a function doing string appends. - remove unused JS_GetClassName() R=thestig@chromium.org Review URL: https://codereview.chromium.org/963193003
2015-02-24Convert pdfium expected test results to PNG format.Tom Sepez

2015-02-19Add test for PDF's JS "global".Tom Sepez
Exercises a separate code path that stores some JS objects outside of JS. Needed before re-writing some other portions of the JS_Defines.h code. R=jam@chromium.org Review URL: https://codereview.chromium.org/943783002
2015-02-13Run pixel tests via automated script.Tom Sepez
On origin/master, we only have .ppm format support, so the expected output files would take up a lot of space. Hence, this may not get going until XFA hits with its .png support. Nor is there a good way to diff these; XFA provides this for .png as well. But this will provide at least one automated test to ensure that we've got non-blank output, at least for one trivially simple case.

Along the way, I rename some functions in pdfium_test.cc to match the style guide's FunctionName() syntax, adding "Example" to make them obviously different from the PDF internal code with similar name fragments. The purpose is to at least have some coverage for the setter/getter macros from JS_Define.h R=thestig@chromium.org Review URL: https://codereview.chromium.org/928573002
2015-02-12Create run_javascript_tests.pyTom Sepez
Top level script driver for testing/resources/javascript. Converts each input template file in that directory to a .pdf file in the working directory (typically out/Debug/gen/pdfium/testing/resources/javascript), invokes pdfium_test on it to generate , and crudely diffs the expected output. We can now remove generated .pdfs from source control, keeping only the hand-editable .in templates. R=thestig@chromium.org Review URL: https://codereview.chromium.org/912803004

2015-02-06First JavaScript testing implementation.Tom Sepez
This is a plan for testing JS inside of pdf files under pdfium: Communication of results will be done via app.alert(), rather than console.println(), since the latter is not hooked up to any API callbacks. pdfium_test.cc is modified to be more careful about use of stdout/stderr, so that only the app.alert() and the unsupported feature callback use stdout. Diffing stdout against ..._expected.txt files gives the result. I added a /javascript directory to separate these from the embeddertest resources. The alert callback is backported from XFA. This was an omission. BUG=https://code.google.com/p/pdfium/issues/detail?id=62 R=jam@chromium.org, thestig@chromium.org Review URL: https://codereview.chromium.org/872103003
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).
