2014-12-17Add a small LRU cache for the JBIG2 symbol dictionary.Bo Xu
This reduces rendering time on my test document by over 10 seconds. It is super common for a JBIG2 dictionary to span multiple pages, so we don't want to decode the same dictionary over and over again. Original patch from Jeff Breidenbach (breidenbach@gmail.com) BUG=https://code.google.com/p/pdfium/issues/detail?id=85 R=bo_xu@foxitsoftware.com, thestig@chromium.org Review URL: https://codereview.chromium.org/761313004
2014-12-12Avoid duplicate definitions of JSCONST_n*Hash and QeTable variables.Bruce Dawson
QeTable is a 752 byte array that was defined in a header file. This caused it to be instantiated by the VC++ compiler 12 times, wasting 8,272 bytes of space in the data segment. Because 'const' implies 'static' this did not cause any duplicate symbol errors. JSCONST_n*HASH are a set of eight variables that are defined in a header file. This causes them to be replicated 15 times. The variables themselves are tiny but they are dynamically initialized and this dynamic initialization code is replicated 15 times. When tested on pdfium_test.exe the effect of this change is to: Reduce the .text (code) segment by 3,616 bytes. Reduce the .rdata section by 8,656 bytes. Reduce the total binary file size by 13312 bytes. These are the worst offenders for pdf.dll as shown in: https://drive.google.com/open?id=1BvubxoA2SU_2e4T5cq7jHTjc1TlT0qOndpIfX3DMeA8&authuser=0 This will also drastically simplify the list of work to be done for bug 441899 (getting rid of initializers).

2014-09-02Tidy up opj_ callback functions in fx_codec_jpx_obj.cppTom Sepez
This is code cleanup rather than bug fixing. The motivation for this was to fix the casts at line 97 of the original file. These are wrong; you cannot correct via casting a function signature mismatch when passing a function as an argument. In theory, there's no reason to believe that the compiler will pass args in the same manner for a function of type (void*, size_t, void*) as for a function of type (void*, size_t, some_struct*). The cast will suppress the compile error, but you can't be assured the call will work as intended. In practice, it does, since the last architecture where a void* had a different representation than a struct* went extinct in the late 80s. In the functions themselves, note that we currently bail out if srcData->offset >= srcData->src_size, so the expression bufferLength = (OPJ_SIZE_T)(srcData->src_size - srcData->offset) will always be > 0. Hence the check if(bufferLength <= 0) is pointless, esp. since bufferLength is a signed type and < 0 makes no sense. The opj_seek_from_memory() has a bool return value, so returning -1 on error doesn't seem reasonable. Change this to TRUE/FALSE, and return false on seek past end. If we're truly passing readonly data, then perhaps it makes sense to make the write() function always return -1. I didn't do this. Lastly, I capitalize "DecodeData" so that it looks like a struct, and change its members to be size_t's to avoid casting back and forth.

- Silence -Wheader-hygiene warning on Clang. Between fx_agg_driver.cpp and fxjs_v8.h there are hundreds or thousands of things that depend on "using namespace", so it is best to just suppress this warning than fix it. - gzguts.h: Include unistd.h on all non-Windows platforms, not just Apple platforms. Fixes implicit include warnings on Linux. - Added parens to silence a warning about mixing && and ||. - Removed a check if an enum is negative. Enums can be unsigned, generating an always-false warning. The check isn't necessary. - Removed some statements that are just names of variables that do nothing.
