72bd486337 Refactor QPDF::parse_xrefEntry 
Move reading of the entry from read_xrefTable to parse_xrefEntry.

Split parse_xrefEntry into two new methods read_xrefEntry and
read_bad_xrefEntry. read_xrefEntry is optimised for reading
correct entries. To handle incorrect entries it calls read_bad_xrefEntry,
which is largely unchanged from parse_xrefEntry.

e9166457fa Tweak pull request contribution on fixing non-standard basic_string_view 2024-03-03 13:40:59 -05:00
Zoe Clifford
07bc363224 string_view leads to char_traits which is not standard C++ (background in #1024). 
This triggers compilation failures with certain C++20 compiler configurations.

To avoid this I moved the cast to the loop's body.

cb0f390cc1 Handle parse error stream data (fixes #1123) 
A parse error in stream data in which stream data contained a nested
object would cause a crash because qpdf was not correctly updating its
internal state. Rework the QPDF json reactor to not be sensitive to
parse errors in this way.

6e3b7982db Fix incorrect handling of invalid negative object ids 
Fix two errors introduced in #1110 and #1112. Since
#1110, encountering the invalid indirect reference #1110
-2147483648 n R produces an integer underflow which, if
 undetected, immediately trigger a logic error. Since
 #1112, object -1 0 R may be incorrectly identified as
 an earlier generation of itself and deleted,
 invalidating a live iterator.
