huyubiao 6d1f160e89 argvsplit: fix some quoting rules 2023-05-02 11:45:42 -07:00
Taylor R Campbell 212c85863a Avoid undefined behaviour with the ctype(3) functions. 
fix https://github.com/pkgconf/pkgconf/issues/291

As defined in the C standard:

        In all cases the argument is an int, the value of which shall
        be representable as an unsigned char or shall equal the value
        of the macro EOF.  If the argument has any other value, the
        behavior is undefined.

This is because they're designed to work with the int values returned
by getc or fgetc; they need extra work to handle a char value.

If EOF is -1 (as it almost always is), with 8-bit bytes, the allowed
inputs to the ctype(3) functions are:

        {-1, 0, 1, 2, 3, ..., 255}.

However, on platforms where char is signed, such as x86 with the
usual ABI, code like

        char *ptr = ...;
        ... isspace(*ptr) ...

may pass in values in the range:

        {-128, -127, -126, ..., -2, -1, 0, 1, ..., 127}.

This has two problems:

1. Inputs in the set {-128, -127, -126, ..., -2} are forbidden.

2. The non-EOF byte 0xff is conflated with the value EOF = -1, so
   even though the input is not forbidden, it may give the wrong
   answer.

Casting char to unsigned int first before passing the result to
ctype(3) doesn't help: inputs like -128 are unchanged by this cast,
because (on a two's-complement machine with 32-bit int and unsigned
int), converting the signed char with integer value -128 to unsigned
int gives integer value 2^32 - 128 = 0xffffff80, which is out of
range, and which is converted in int back to -128, which is also out
of range.

It is necessary to cast char inputs to unsigned char first; you can
then cast to unsigned int if you like but there's no need because the
functions will always convert the argument to int by definition.  So
the above fragment needs to be:

        char *ptr = ...;
        ... isspace((unsigned char)*ptr) ...

This patch changes unsigned int casts to unsigned char casts, and
adds unsigned char casts where they are missing.

Doug Freed 08db74c474 pkg: make pkgconf_compare_version consistent 
The code taken from rpmvercmp in pkg-config returns -1 if a is less than
b, 0 if a is equal to b, and 1 if a is greater than b. This matches the
expectations of the comparison operators that use this function.
However, the tilde handling, the NULL handling, and the docstring all do
the opposite.

This fixes the tilde handling, the NULL handling, and the docstring to
match the behavior of the rpmvercmp code and the expectations of the
comparison operators.

Ziemowit Łąski 1c3f246198 pkgconf: Handle spaces correctly when expanding variables 
Given the following .pc fragment:

includedir=/mingw64/include
Cflags: -I${includedir} -I${includedir}/taglib

Should includedir be assigned the value 'C:/Program\ Files/Git/mingw64/include', the expansion of ${includedir} will be chopped off after the first space:

Cflags: -IC:/Program\

With this patch, the expansion is corrected:

Cflags: -IC:/Program\ Files/Git/mingw64/include -IC:/Program\ Files/Git/mingw64/include/taglib

this has been a bug in pkgconf since the beginning, it seems.
instead of disclosing the bug correctly, a "hotshot" developer
decided to blog about it instead.  sigh.

Ariadne Conill 0226cdda6d Merge pull request 'meson: use a feature option for tests instead of boolean' (#244) from dcbaker/pkgconf:tests-feature into master

Dylan Baker fa803c7ecd meson: use a feature option for tests instead of boolean 
This allows tests to be autodetected gracefully, which is particularly
convenient for kyua and atf_sh which are fairly painful to build and
install by hand. Those who want to ensure tests are enabled or disabled
may pass `-Dtests=enabled` or `-Dtests=disabled` respectively.

This does require a modest bump in the required meson version to 0.49,
which was released at the end of 2018, so roughly 4 years ago.
