This is a variant of g_file_get_path() which returns a const string to
the caller, rather than transferring ownership.
I've been carrying `gs_file_get_path_cached()` in libgsystem and it
has seen a lot of use in the ostree and flatpak codebases. There are
probably others too.
I think language bindings like Python/Gjs could also use this to avoid
an extra malloc (i.e. we could transparently replace
`g_file_get_path()` with `g_file_peek_path()`.
(Originally by Colin Walters. Tweaked by Philip Withnall to update to
2.56, change the function name and drop the locking.)

In order to enrich information displayed by GApplication command line
handling when --help is invoked, 3 new methods are proposed:
. g_application_set_option_context_parameter_string
. g_application_set_option_context_summary
. g_application_set_option_context_description
Those methods interact with the GApplication's internal GOptionContext
which is created for command line parsing in g_application_parse_command_line.
(please refer to the GOptionContext class for more information about option
context, parameter string, summary and description.)
To illustrate the 3 methods, an example is provided:

In the vast majority of cases, we can avoid temporary
allocations for paths in g_resources_enumerate_children().
In the case we need to add a suffix "/", we can usually just
build the path on the stack. In other cases, we can completely
avoid the strdup, which appears to only have been added for
readability. If the path is really long, we fallback to doing
what we did before, and use g_strconcat().
In the case of Builder, this saved 5.3mb of temporary
allocations in the process of showing the first application
window.
https://bugzilla.gnome.org/show_bug.cgi?id=790275
Previously, the path canonicalization for resources had liberal use of
strlen() and memmove() while walking through the path. This patch avoids
any secondary strlen() and removes all use of memmove().
A single allocation is created up front as we should only ever need one
additional byte more than then length of the incoming path string.
To keep the implementation readable, the mechanics are kept in external
functions. memrchr() was not used due to its lack of portability.
This is faster in every test case I've tested. Paths that contain
relative ../ have the most speedup.

The patch basically just grabs the implementation of g_content_type_get_icon_internal()
from gcontenttype.c - the only difference is that it first converts UTI to MIME using
g_content_type_get_mime_type() and at the end frees this temporary MIME type.

This commit adds new W32-only functions to gstdio.c,
and a new header file, gstdioprivate.h.
These functions are:
g_win32_stat_utf8()
g_win32_lstat_utf8()
g_win32_fstat()
and they fill a private structure, GWin32PrivateStat,
which has all the fields that normal stat has, as well as some
extras.
These functions are then used throughout glib and gio to get better
data about the system. Specifically:
* Full, 64-bit size, guaranteed (g_stat() is forced to use 32-bit st_size)
* Full, 64-bit file identifier (st_ino is 0 when normal stat() is used, and still is)
* W32 File attributes (which stat() doesn't report); in particular, this allows
symlinks to be correctly identified
* Full, 64-bit time, guaranteed (g_stat() uses 32-bit st_*time on 32-bit Windows)
* Allocated file size (as a W32 replacement for the missing st_blocks)
st_mode remains unchanged (thus, no S_ISLNK), so when these are given back to
glib users (via g_stat(), for example, which is now implemented by calling g_win32_stat_utf8),
this field does not contain anything unexpected.
g_lstat() now calls g_win32_lstat_utf8(), which works on symlinks the way it's supposed to.
Also adds the g_win32_readlink_utf8() function, which behaves like readlink()
(including its inability to return 0-terminated strings and inability to say how large
the output buffer should be; these limitations are purely for compatibility with
existing glib code).
Thus, symlink support should now be much better, although far from being complete.
A new W32-only test in gio/tests/file.c highlights the following features:
* allocated size
* 64-bit time
* unique file IDs

We're eventually going to drop Autotools, but in the meantime we should
probably use idiomatic options and reduce warnings.
GLib is pretty much already safe for subdir-objects to be enabled,
except in the GIO tests, where the build references files that are
generated in a different level. For that, we can use the same solution
employed by GTK+, and link the appropriate file in the right
sub-directory.

During testing with gdk-pixbuf I noticed failures during content type
to mime conversion. The root reason was the unsafe conversion used
in create_cstr_from_cfstring. The problem was addressed in commit
c60226e0a1 but that was reverted. I noticed the commit only
when I had fixed the problem. In addition I added a test to check
the content type to mime conversion on MacOS. This problem is
discussed in Bug #788936.

This patch introduces the use of the xdgmime system to guess

Add testcase for function g_file_query_filesystem_info()
reporting outdated info for "filesystem::readonly" attribute
when said attribute was different in a previous mounted
partition in the same device (as GIO maintains a mounts cache
per 'st_dev' stat() member).
To trigger a mount operation, testcase uses program 'bindfs'
instead of 'mount --bind' as bindfs does not require root
privileges. And 'fusermount -u' command is used to unmount said
bindfs mount.
As a reference in Fedora, 'bindfs' is installed from 'bindfs'
package and 'fusermount' from 'fuse' package (this one is installed
by default as being part of 'System Tools' group).
The test creates a directory with a file in it, then mounts it
readonly over another directory (the mountpoint), it then checks
that g_file_query_filesystem_info() for the file in it indeed reports
"filesystem::readonly" as TRUE. Then unmounts and mounts again this
time rw (not readonly), it then checks again if g_file_query_filesystem_info()
is reporting "filesystem::readonly" as TRUE, if that's the case, it
confirms the bug by opening said file in write mode.
Testcase is only added for Unix builds.

Some of the dependencies' build systems for Visual Studio do not provide a
pkg-config file upon build, so we use find_library() for them when the
corresponding pkg-config files are not found during Visual Studio builds,
so that one will not need to make up pkg-config files for them, which
could be error-prone. These .lib names match the names that are built
with the officially supported build system that is used by their
respective Visual Studio support.
For ZLib, this will make gio-2.0.pc reflect on the zlib .lib based on
what is found, or whether we use the fallback/bundled ZLib, when we
don't have a pkg-config file for ZLib on MSVC. We still need to depend
on Meson to be updated to put the correct link argument for linking ZLib
in the pkg-config case.

Prevent the situation where errno is set by function A, then function B
is called (which is typically _(), but could be anything else) and it
overwrites errno, then errno is checked by the caller.
errno is a horrific API, and we need to be careful to save its value as
soon as a function call (which might set it) returns. i.e. Follow the
pattern:
int errsv, ret;
ret = some_call_which_might_set_errno ();
errsv = errno;
if (ret < 0)
puts (strerror (errsv));
This patch implements that pattern throughout GLib. There might be a few
places in the test code which still use errno directly. They should be
ported as necessary. It doesn’t modify all the call sites like this:
if (some_call_which_might_set_errno () && errno == ESOMETHING)
since the refactoring involved is probably more harmful than beneficial
there. It does, however, refactor other call sites regardless of whether
they were originally buggy.
