2020-12-28Add QPDFObjectHandle::setFilterOnWriteJay Berkenbilt
2020-12-28Add ostream << for QPDFObjGenJay Berkenbilt
2020-12-28Let optimize filter stream parameters instead of making them directJay Berkenbilt
Also removes preclusion of stream references in stream parameters of filterable streams and reduces write times by about 8% by eliminating an extra traversal of the objects.
2020-12-28Restructure optimize to allow skipping parameters of filtered streamsJay Berkenbilt
2020-12-28Refactor: separate code that determines whether to filter a streamJay Berkenbilt
2020-12-28Test empty function detectionJay Berkenbilt
2020-12-28Implement user-provided stream filtersJay Berkenbilt
Refactor QPDF_Stream to use stream filter classes to handle supported stream filters as well.

2020-10-31Fix stack overflow on direct root (fuzz issue 26761)Jay Berkenbilt
2020-10-31Add comments explaining the foreign object copying codeJay Berkenbilt
These are the comments I would have liked to have been able to read while fixing #449 and #478.
2020-10-31Fix foreign stream copying bug (fixes #478)Jay Berkenbilt
This reverts an incorrect fix to #449 and codes it properly. The real problem was that we were looking at the local dictionaries rather than the foreign dictionaries when saving the foreign stream data. In the case of direct objects, these happened to be the same, but in the case of indirect objects, the object references could be pointing anywhere since object numbers don't match up between the old and new files.
2020-10-31Better indirect filter test caseJay Berkenbilt
The test suite now contains test cases that fail with both 10.0.1 and 10.0.2 and reproduce the internal error from #449.

2020-10-27Improve efficiency of number to string conversionJay Berkenbilt
2020-10-27Revert removal of unreadCh change for performanceJay Berkenbilt
Turns out unreadCh is much more efficient than seek(-1, SEEK_CUR). Update comments and code to reflect this.

2020-10-27Release notes for 10.0.2Jay Berkenbilt
2020-10-26Add some missing ChangeLog entriesJay Berkenbilt
2020-10-25Use sha256 for signing release filesJay Berkenbilt
2020-10-25Build Windows releases with openssl; automate external librariesJay Berkenbilt
External libraries for Windows are now built automatically in the qpdf/external-libs repository and include openssl in addition to zlib and jpeg. Use these, and update the Windows build to build with the openssl crypto provider by default. We leave the native crypto provider enabled in case there is a problem with openssl and also to continue to exercise that code.
2020-10-25Make libtests depend on qpdfJay Berkenbilt
We need to run qpdf --show-crypto.
2020-10-23TODO and comments item for pipeContentStreamsJay Berkenbilt
2020-10-23With --no-warn, suppress warnings in split-pagesJay Berkenbilt
Warnings issued on the output QPDF object were not suppressing warnings since that option was only set on the input QPDF object.

* Return rather than exiting from realmain in qpdf.cc * Remove extraneous blank line * Don't assign temporary to const reference
2020-10-22Handle jpeg library fuzz false positivesJay Berkenbilt
The jpeg library has some assembly code that is missed by the compiler instrumentation used by memory sanitization. There is a runtime environment variable that is used to work around this issue.
