Implementation of PUGIXML_STATIC_CRT for newer CMake versions (3.15+)
depend on MSVC_RUNTIME_LIBRARY, but this only works if the policy
is defined *before* the project.
Different OSes have different behavior when trying to fopen/fseek/ftell
a folder. On Linux, some systems return 0 size, some systems return an
error, and some systems return LONG_MAX. LONG_MAX is particularly
problematic because that causes spurious OOMs under address sanitizer.
Using fstat manually cleans this up, however it introduces a new
dependency on platform specific headers that we didn't have before, and
also has unclear behavior on 64-bit systems wrt 32-bit sizes which will
need to be tested further as I'm not certain if the behavior needs to be
special-cased only for MSVC/MinGW, which are currently not handled by
this path (unless MinGW defines __unix__...)
We use snprintf when stdc is set to C++11, however in C++98 mode we can't use variadic macros,
and Xcode 14 complains about the use of sprintf.
It should be safe however to use variadic macros on any remotely recent version of clang on Apple,
unless -pedantic is defined which warns against the use of variadic macros in C++98 mode...
This change fixes the problem for the builds that don't specify -pedantic, which is a problem for
another day.
This also turns the define for PUGIXML_API into an `$<IF:>`, instead of an
`$<IF:>` with an empty true condition. If this is inadequate, I will
undo it, and place them on separate lines as they were before, but will
most likely use an inverse `$<NOT:>` instead of an `$<IF:>`.
There were two conditions under which xml_document::save_file could
previously return true even though the saving failed:
- The last write to the file was buffered in stdio buffer, and it's that
last write that would fail due to lack of disk space
- The data has been written correctly but fclose failed to update file
metadata, which can result in truncated size / missing inode updates.
This change fixes both by adjusting save_file to fflush before the check,
and also checking fclose results. Note that while fflush here is
technically redundant, because it's implied by fclose, we must check
ferror explicitly anyway, and so it feels a little cleaner to do most of
the error handling in save_file_impl, so that the changes of fclose()
failing are very slim.
Of course, neither change guarantees that the contents of the file are
going to be safe on disk following a power failure.
This cleans up xml_attribute::set_value to be uniform wrt
xml_node::set_value and xml_text::set_value - for now we duplicate the
body since the logic is trivial and this keeps debug performance
excellent.
This fixes compilation of pugixml with -fvisibility=hidden. Without
this patch, one would get lots of unresolved symbols when consuming
pugixml as a shared library.
This is the same fix as #497, but we're using auto_deleter instead
because if allocation function throws, we can't rely on an explicit call
to deallocate.
Comes along with two tests that validate the behavior.
Instead of trying to detect if we can safely use random shuffle simply reimplement it ourselves.
The quality of the RNG is not essential for these tests.
WinCE lacks most recent CRT additions to MSVC; we used to explicitly disable specific sections
of code, but it's more comprehensive to just specify that the CRT is from MSVC7 instead of MSVC8.
Fixes#401
Fix include in test_document.cpp when building against libc++. The _GLIBCXX_HAVE_UNISTD_H relies on pugixml and its tests being built against libstdc++, with LLVM's libc++ this won't be defined
Options marked as advanced are hidden by default in the CMake GUI.
The `PUGIXML_HEADER_ONLY` are redundant when during CMake builds, hence
removed.
The `PUGIXML_HAS_LONG_LONG` should be handled automatically and needs to
be rewritten, hence these options has been removed.
This commit reverts back to exposing the global variable
BUILD_SHARED_LIBS.
Since building static libraries are the default for CMake
(i.e. BUILD_SHARED_LIBS=OFF) the option to build both static and shared
libraries were moved into a conditional option. So the option
PUGIXML_BUILD_SHARED_AND_STATIC is now only visible when the global
BUILD_SHARED_LIBS variable is set to ON.
The change also prevents the case were the user first enables
BUILD_SHARED_LIBS and then enables PUGIXML_BUILD_SHARED_AND_STATIC to
then again disable BUILD_SHARED_LIBS.
Replace `add_definitions` with `target_compile_definitions` for
specified targets. Multiple options are separated using the
`separate_arguments` function, which converts any string using
space-separated arguments into a semicolon-separated list.
The ability to use custom build defines were removed in commit:
1c5a0bb32583fd294022e68e66b541bf6ff71a67
This commit will reintroduce this feature, but using a prefixed variable
name.
Added PUGIXML as prefix to all CMake options to avoid naming collisions
with downstream projects.
Removed the cached variable BUILD_DEFINES, since it was unused.
Previously when copying the allocator state we would copy an incorrect
root pointer into the document's current state; while this had a minimal
impact on the allocation state due to the fact that any new allocation
would need to create a new page, this used a potentially stale field of
the moved document when setting up new pages, which could create issues
in future uses of the pages.
This change fixes the core problem and also removes the use of the
_root->allocator from allocate_page since it's not clear why we need it
there in the first place.
Since foo//bar//baz adds two nodes for each //, we need to increment the
depth by 2 on each iteration to limit the AST correctly.
Fixes the stack overflow found by cluster-fuzz (I suspect the issue
there is a bit deeper, but this part is definitely a bug and as such I'd
rather wait for the next test case for now).
