8ccd3a8a89 Mark weak encryption with API changes (fixes #576) 2022-04-30 17:24:15 -04:00
Jay Berkenbilt
4f24617e1e Code clean up: use range-style for loops wherever possible
Where not possible, use "auto" to get the iterator type.

Editorial note: I have avoid this change for a long time because of
not wanting to make gratuitous changes to version history, which can
obscure when certain changes were made, but with having recently
touched every single file to apply automatic code formatting and with
making several broad changes to the API, I decided it was time to take
the plunge and get rid of the older (pre-C++11) verbose iterator
syntax. The new code is just easier to read and understand, and in
many cases, it will be more effecient as fewer temporary copies are
being made.

m-holger, if you're reading, you can see that I've finally come
around. :-)

c71e41e9d9 Change handling of qpdf fuzz corpus
Files are copied into the build area rather than left in the source
tree, and the test suite looks for them there. Also remove special
case around counting files in the qpdf corpus.

cb769c62e5 WHITESPACE ONLY -- expand tabs in source code
This comment expands all tabs using an 8-character tab-width. You
should ignore this commit when using git blame or use git blame -w.

In the early days, I used to use tabs where possible for indentation,
since emacs did this automatically. In recent years, I have switched
to only using spaces, which means qpdf source code has been a mixture
of spaces and tabs. I have avoided cleaning this up because of not
wanting gratuitous whitespaces change to cloud the output of git
blame, but I changed my mind after discussing with users who view qpdf
source code in editors/IDEs that have other tab widths by default and
in light of the fact that I am planning to start applying automatic
code formatting soon.

9044a24097 PointerHolder: deprecate getPointer() and getRefcount()
Use get() and use_count() instead. Add #define
NO_POINTERHOLDER_DEPRECATION to remove deprecation markers for these
only.

This commit also removes all deprecated PointerHolder API calls from
qpdf's code except in PointerHolder's test suite, which must continue
to test the deprecated APIs.

e4ef3d1540 Remove original qpdf fuzz seed corpus from tests
Since the introduction of fuzz testing, there has never been a problem
found because of a failure of a file in the fuzzer seed corpus. As the
fuzzer has found problems, they have been added to the test suite, and
that should be adequate to exercise the fuzzers in the tesing
environment as well as providing adequate regression testing.

Removing these original files shaves many minutes off the builds in CI.

ef127001b3 Remove some fuzz files with Mal/PDFEx-H (fixes #460)
There isn't really an issue with these files causing a real problem,
but malware and virus checkers trip on them, and the value to leaving
them in the test suite is too low to be worth the hassle.

0e51a9aca6 Don't encrypt trailer, fixes fuzz issue 15983
Ordinarily the trailer doesn't contain any strings, so this is usually
a non-issue, but if the trailer contains strings, linearizing and
encrypting with object streams would include encrypted strings in the
trailer, which would blow out the padding because encrypted strings
are longer than their cleartext counterparts.

47a38a942d Detect stream in object stream, fixing fuzz 16214
It's detected in QPDFWriter instead of at parse time because I can't
figure out how to construct a test case in a reasonable time. This
commit moves the fuzz file into the regular test suite for a QTC
coverage case.

8f06da7534 Change list to vector for outline helpers (fixes #297)
This change works around STL problems with Embarcadero C++ Builder
version 10.2, but std::vector is more common than std::list in qpdf,
and this is a relatively new API, so an API change is tolerable.

Thanks to Thorsten Schöning <6223655+ams-tschoening@users.noreply.github.com>
for the fix.
