Jay Berkenbilt 9a398504ca Refactor QUtil::read_lines_from_file 
This commit adds the preserve_eol flags but doesn't implement EOL
preservation yet.

Jay Berkenbilt c4478e5249 Allow odd/even modifiers in numeric range (fixes #364) 2019-11-09 13:23:12 -05:00
Jay Berkenbilt 4fa7b1eb60 Add remove_file and rename_file to QUtil 2019-08-31 15:51:04 -04:00
Jay Berkenbilt 6c39aa8763 In shippable code, favor smart pointers (fixes #235) 
Use PointerHolder in several places where manually memory allocation
and deallocation were being used. This helps to protect against memory
leaks when exceptions are thrown in surprising places.

Jay Berkenbilt 1bde5c68a3 Add QUtil::read_file_into_memory 
This code was essentially duplicated between test_driver and
standalone_fuzz_target_runner.

Jay Berkenbilt c6cfd64503 Rename QUtil::strcasecmp to QUtil::str_compare_nocase (fixes #242) 2019-06-21 22:29:31 -04:00
Jay Berkenbilt a35d4ce9cc Fix bounds error in utf16_to_utf8 conversion 2019-06-21 17:40:24 -04:00
Jay Berkenbilt d71f05ca07 Fix sign and conversion warnings (major) 
This makes all integer type conversions that have potential data loss
explicit with calls that do range checks and raise an exception. After
this commit, qpdf builds with no warnings when -Wsign-conversion
-Wconversion is used with gcc or clang or when -W3 -Wd4800 is used
with MSVC. This significantly reduces the likelihood of potential
crashes from bogus integer values.

There are some parts of the code that take int when they should take
size_t or an offset. Such places would make qpdf not support files
with more than 2^31 of something that usually wouldn't be so large. In
the event that such a file shows up and is valid, at least qpdf would
raise an error in the right spot so the issue could be legitimately
addressed rather than failing in some weird way because of a silent
overflow condition.

Jay Berkenbilt 4ecd1df6f2 Add configure option AVOID_WINDOWS_HANDLE

to Windows builds.
