Jay Berkenbilt 5f0708418a Add iterators to name/number tree helpers 2021-01-24 03:22:59 -05:00
Jay Berkenbilt 4a1cce0a47 Reimplement name and number tree object helpers 
Create a computationally and memory efficient implementation of name
and number trees that does binary searches as intended by the data
structure rather than loading into a map, which can use a great deal
of memory and can be very slow.

Jay Berkenbilt bcea54fcaa Revert removal of unreadCh change for performance 
Turns out unreadCh is much more efficient than seek(-1, SEEK_CUR).
Update comments and code to reflect this.

Jay Berkenbilt bed165c9fc Stop using InputSource::unreadCh 2020-10-18 07:43:05 -04:00
Jay Berkenbilt 18b34a5649 InputSource::unreadCh -- only unread most recently read character 
This is all that ever worked. The test suite was trying to do
something different from ClosedFileInputSource.

Jay Berkenbilt 578c5ac66c Use more references when iterating 
When possible, use `for (auto&` or `for (auto const&` when iterating
using C++-11 style iterators.

Fabrice Fontaine d043c6b828 libtests/cxx11.cc: fix build with gcc 4.8 
Build fails on gcc 4.8 since version 9.1.1 and commit
752416554086d5d34323bc14164d5084db83cfbd:

libtests/cxx11.cc: In function 'void do_regex()':
libtests/cxx11.cc:347:42: error: 'strlen' is not a member of 'std'
     std::cregex_iterator m3(str7, str7 + std::strlen(str7), expr4);
                                          ^

To fix the build failure, add missing include on cstring

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 1639d972ea Run libtests for crypto with all available providers 
If QPDF_CRYPTO_PROVIDER is set, just run the tests for the given
provider. This is to support cases of running the entire test suite
for each provider. If QPDF_CRYPTO_PROVIDER is not set, run the tests
that exercise the cyrpto provider for each available provider.

standalone_fuzz_target_runner.

Jay Berkenbilt 79f6b4823b Convert remaining public classes to use Members pattern 
Have classes contain only a single private member of type
PointerHolder<Members>. This makes it safe to change the structure of
the Members class without breaking binary compatibility. Many of the
classes already follow this pattern quite successfully. This brings in
the rest of the class that are part of the public API.

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 da7c2c0ee9 Fix json serialization for {x | -1 < x < 1} (fixes #308)
