2015-05-06Fix a couple of divide by zero crashes in PNG/TIFF predictors.Lei Zhang
BUG=484002 R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1124563002
2015-05-05Expose additional flags for rasterization.Scott Byer
These flags are unused in Chromium, but are needed for the Cloud Print conversion process, which takes PDF and produces a raster for low-end printers. Certain low-end printers (e.g., B&W laser printers) will turn anti-aliased text into a mess. The existing printing flag isn't sufficient, as other kinds of printers will still want some kinds of anti-aliasing to occur for best results. BUG=482253 TEST=none R=vitalybuka@chromium.org Review URL: https://codereview.chromium.org/1115513002 Patch from Scott Byer <scottbyer@chromium.org>.
2015-05-05Make sure string constructors are efficient on literalsTom Sepez
Separate out the overload when the length is not known, and be sure that strlen() call is in the header so that strlen("foo") => 3 (since many compilers support this optimization). Also delete some unused types. BUG=pdfium:151 R=thestig@chromium.org Review URL: https://codereview.chromium.org/1117263004
2015-05-04Fix issues with != and == in fx_basic_wstringTom Sepez
Part two. Fix same issue in wide strings as in their bytestring counterparts. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1127753002
2015-05-04Kill FX_DEFINEHANDLETom Sepez
I spent at least 2 minutes grep'ing for a class or struct (on the other branch) that was delcared using this. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1129433002
2015-05-04Fix issuse with != and == shown by fx_basic_bstring unit tests.Tom Sepez
R=thestig@chromium.org Review URL: https://codereview.chromium.org/1125703004
2015-05-01Backfill some FX StringC unit tests for == and !=.Tom Sepez
Continuation of https://codereview.chromium.org/1122573002 Applies similar test to immutable versions of strings. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1118973005
2015-05-01Backfill some FX String unit tests for == and !=.Tom Sepez
... and there are a few inconsistencies which we can now fix. Also add a comment about why these strings aren't headed for the dust-bin long term. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1122573002
2015-05-01Save 4 bytes per CFX_ByteString where intptr_t smaller than long.Tom Sepez
Also prevent theoretical roll-over where long smaller than intptr_t. See bug for discussion. BUG=pdfium:149 R=thestig@chromium.org Review URL: https://codereview.chromium.org/1117413002
2015-05-01Save 8 bytes in each CFX_ByteString/WideString (on "LP64" platforms).Tom Sepez
(Also makes the calculation robust in face of changes to the header). BUG=pdfium:149 R=thestig@chromium.org Review URL: https://codereview.chromium.org/1118983003
2015-05-01Adjust the visibility of the standalone targets in the GN build.Dirk Pranke
As part of the migration from GYP->GN, we want to make sure that we can track when new targets are added to either the GYP or GN builds and that we are building everything we expect to build. In GN, unlike GYP, if a build file gets referenced from other files, building 'all' will cause every target to be built in it. This means in particular, that we can end up trying to build targets that are not necessarily intended to be visible to the rest of the build. To get around this, any target that is defined but hidden (like 'pdfium_unittests', ) should still be visible to a top-level target called "//:gn_visibility".

2015-04-30Take adavange of unused bytes at end of widestringTom Sepez
Follow-on to https://codereview.chromium.org/1120703003/ R=thestig@chromium.org Review URL: https://codereview.chromium.org/1112423003
2015-04-30Try to take advantage of unused bytes at end of CFX_ByteString.Tom Sepez
Given the representation of StringData, it seems sub-optimal not to be doing this. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1120703003
2015-04-30Provide an array buffer allocator to V8.chromium/2395chromium/2394chromium/2393chromium/2392chromium/2391chromium/2390chromium/2389chromium/2388Tom Sepez
This allows PDFium to work with current V8, so unpin v8 in the pdfium DEPS file. (I also re-ordered one field in CJS_Runtime, just to put two bools together (may pack tighter), and to put all the v8 stuff together). BUG=pdfium:146 R=thestig@chromium.org Review URL: https://codereview.chromium.org/1118043002
2015-04-29Add suppressions for all new failing corpus tests.Tom Sepez
TBR=thestig@chromium.org Review URL: https://codereview.chromium.org/1111393004
2015-04-29Corpus roll to pick up the 2015-04-28 Foxit drop.Tom Sepez
This will undoubtedly red up the tree, as we don't have trybots. A follow-up CL will add the suppressions required for each platform at the moment. The new suppressions in this CL are for cases where we didn't generate an expected result file (due to the issue in fx/FRC_3.5_part1/Introduction.txt).

2015-04-27Fix windows-specific usage of CFX_WideStr::operator LPCWSTR().Tom Sepez
Carry-on from https://codereview.chromium.org/1108903002/ R=brucedawson@chromium.org Review URL: https://codereview.chromium.org/1103343002
2015-04-27Reduce usage of operator LPCWSTR from CFX_WideString().Tom Sepez
This involves adding some explicit c_str() calls. Doing so flagged PDF_EncodeText() and FindOptionValue() as having suboptimal signatures, in that we are often throwing away a perfectly fine length and recomputing it. There are still some platform-specific code that needs the operator. R=brucedawson@chromium.org Review URL: https://codereview.chromium.org/1101933003
2015-04-27Revert "Kill operator LPCWSTR from CFX_WideString()."Tom Sepez
This reverts commit 15a62973b9b89c3e229cc0ab501c45967f91b325. Reason for revert: broke build on windows, mac. I must have missed some platform-specific conversions. TBR=brucedawson@chromium.org Review URL: https://codereview.chromium.org/1108883002

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
2015-04-23Kill overloaded cast operators in CJS_Value.Tom Sepez
The red-flag here is the explicit invocation of things like params[1].operator CFX_WideString() rather than static_cast<CFX_WideString>(params[1]) to invoke the conversion. Turns out the above won't compile due to ambiguity given the number of implicit constructors for widestrings. CJS_Value has both constructors and assignment operators for the primitive types, which means that conversions can take place unexpectedly in both directions, a second red flag. We don't want the compiler invoking these at will since it may hide bugs. In fact, when they are removed, three such places were discovered. Also rename ToJSValue to ToV8Value to match the other ToV8xxxxx functions added. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1096813008

2015-04-22Add missing operators for CFX_ByteStringC.Tom Sepez
Removing the implicit cast operator forces a build breakage should we use ByteStringC in STL containers. Adding an operator< restores correct behaviour. Adding an operator[] avoids re-writing some code to call GetPtr() prior to array indexing. Part 1 of 4. R=thestig@chromium.org TBR=brucedawson@chromium.org BUG=pdfium:142.

This is a copy of breakpad's standalone scoped_ptr, which has been renamed to nonstd::unique_ptr, and from which more complicated classes have been removed.
