These functions were deprecated via comments in 1.5 but never got the
deprecated attribute; now is the time!
Using deprecated functions produces a warning; to silence it, this
change moves the relevant tests to a separate translation unit that has
deprecation disabled.
Unify build paths in all MSBuild VS projects and extract common build
logic into functions.
Note that this change changes both VS2010 and VS2013 projects to have
more predictable output paths and fixed output file name (pugixml).
We'd like to build pugixml with both static & dynamic CRT and put it
all in one NuGet package.
CoApp sort of allows us to do this via dynamic/static pivots, but it
does not let us customize the names of the pivots and additionally has
some bugs with the project setup. Their project modifications are also
much more complicated - really, at this point we should do this
ourselves.
Create a simple native NuGet package with Linkage setting that picks the
right library, and package all libraries appropriately. Note that we use
the unified path syntax to make it simple to just get the right .lib
file from the toolset/platform/configuration/linkage combo.
The macro only works correctly when the input argument is an array with
a statically known size - pointers or arrays decayed to pointers won't
work silently.
While this is unlikely to surface issues that aren't caught in
tests/code review, use _countof for MSVC to prevent such code from
compiling.
Correctly check for error codes and don't run .bat file since it doesn't
work anyway (the variables it sets aren't accessible in PowerShell, and
the path to the script doesn't seem to be the same in VS2017).
Add memory allocation failure test for concact with a very large list
and make sure we have every single axis covered with and without a
predicate, with and without a previous step.
Instead of branching code at each invocation site, use variadic macros
to create a wrapping macro that use snprintf for the buffer of a
statically known size.
Variadic macros are supported by all C++11 compilers, as is snprintf;
on MSVC 2005+ we don't necessarily have snprintf, but we can use
_snprintf_s with _TRUNCATE to get the same behavior. In all other cases
we fall back to sprintf, that (theoretically) can lead to a stack buffer
overflow.
In practice all snprintfs used in pugixml use buffers that should be
large enough to never be overflown but snprintf is safe even if this is
not the case.
We use references to arrays elsewhere in the codebase and there's just
one caller for this function so it's easier to fix the size.
This will simplify snprintf refactoring.
codecov.io does not seem to support lcov regex customization;
additionally, we can't just replace unreachable with LCOV_LINE_EXCL
in gcov file - so we have to patch the ##### indicator (which suggests
the line hasn't been hit) with 1.

New tests try to load a folder as an XML document, and a device. Both
are intended to exercise some otherwise non-hittable error paths in
load_file implementation.
This adds tests that complete branch coverage in compact pointer
encoding/decoding code (previously first_attribute was always encoded
using compact encoding in the entire test suite).
Integer sanitizer is flagging unsigned integer overflow in several
functions in pugixml; unsigned integer overflow is well defined but it
may not necessarily be intended.
Apart from hash functions, both string_to_integer and integer_to_string
use unsigned overflow - string_to_integer uses it to perform
two-complement negation so that the bulk of the operation can run using
unsigned integers. This makes it possible to simplify overflow checking.
Similarly integer_to_string negates the number before generating a
decimal representation, but negating is impossible without unsigned
overflow or special-casing certain integer limits.
For now just silence the integer overflow using a special attribute;
also move unsigned overflow into string_to_integer from get_value_* so
that we have fewer functions marked with the attribute.
Fixes#133.
This reverts commit 79109a8546f963d17522d75112cffcfd8cbe35fc.
This warning does not happen on gcc-4.8.4; the workaround introduces an
unsigned integer overflow which results in a runtime error when compiled
with integer sanitizer.
This is accomplished by putting a // fallthrough
comment at the right place.
This seems to be more portable than an attribute-based
solution like [[fallthrough]] or __attribute__((fallthrough)).
Instead of a separate implementation for find/insert, use just one that
can do both. This reduces the code size and simplifies code coverage;
the resulting code is close to what we had in terms of performance and
since hash table is a fall back should not affect any real workloads.
