This is a wrapper around g_private_set() which allocates the desired
amount of memory for the caller and calls g_private_set() on it.
This is intended to make it easier to suppress Valgrind warnings about
leaked memory, since g_private_set() is typically used to make one-time
per-thread allocations. We can now just add a blanket suppression rule
for any allocations inside g_private_set_alloc0().

Check for over- and underflow when manipulating positions.
This makes the sequence
g_list_model_get_item (store, 0);
g_list_model_get_item (store, -1u);
return NULL for the second call, as it should.
Closes: #1639
Calling
g_list_model_get_item (store, 0);
g_list_model_get_item (store, -1u);
does not return NULL for the second call, as it should.
This was showing up in GTK+ list model tests.
Since commit 290bb0dd, where various members of GTask were converted to
a bitfield, some of the getters:
• g_task_get_check_cancellable()
• g_task_get_return_on_cancel()
• g_task_get_completed()
have been returning truthy ints (zero or an arbitrary non-zero integer)
as boolean values, rather than the canonical boolean ints of 1 and 0.
This broke the `yield` statement in Vala, whose generated C code
compares `g_task_get_completed (…) != TRUE`. i.e. Whether the
`completed` field has a value not equal to 1.
Fix this by explicitly converting truthy ints to canonical boolean ints
in all getters.

This is a new polling method allowing to poll more than 64 handles
based on the glib one.
When we reach the limit of 64 we create a thread and we poll
on that thread for a batch of handles this way we overcome the limit.

And mention why it’s not a GInterfaceInitFunc as people who have read
the GObject docs cover-to-cover might expect.

According to msdn documentation last backslash(es) of quoted argument
in a win32 cmdline need to be escaped, since they are
directly preceding quote in the resulting string:
https://docs.microsoft.com/en-us/cpp/c-language/parsing-c-command-line-arguments
Glib <=2.58.0 passed children arguments like C:\Program Files\
without escaping last backslash(es).
So it had been passed as "C:\Program Files\"
windows command line parsing treated this as escaped quote,
and later text was treated as argument continuation instead of separate
arguments.
Existing implementation wasn't easily adoptable to fix this problem,
so escaping logic was rewritten.
Since the resulting length need to be increased due to extra escaping
it was rewritten too. Now the calculated length assumes that all
escapable chars would be escaped in a resulting string,
so the length may be a bit bigger than actually needed,
since backslashes not preceding quotes are not escaped.
This fixes the glib/tests/spawn-singlethread.c test
(which introduced testing for special chars to make this problem
testable).
The problem itself was found during investigations about fixing
related https://gitlab.gnome.org/GNOME/glib/issues/1566
The logic is duplicated in protect_argv_string() and protect_wargv() funcs.
However there is no single obvious way to get rid of duplication -
https://gitlab.gnome.org/GNOME/glib/merge_requests/419#note_371483
So by now adding a note referencing protect_wargv from protect_argv_string,
the other direction is already referenced.
This fixes test that were added in previous commit:
checking for empty stderr failed with coverage enabled, since
coverage warnings printed from gspawn-win32-helper process were treated
as child output. This is fixed by removing redirection after child
finishes execution.
The dup_noninherited renamed to reopen_noninherited,
since it actually always closes passed file descriptor.
Problem was just a typo - wrong variable was checked before enabling
stderr redirection.
This fixes error-only redirection spawn-test added in previous commit.
Behavior while redirecting only stdout should be unaffected,
since old code tried to redirect stderr to -1 in such case,
which silently failed I think.
The spawn_test is enabled on win32 meson build, both msys and msvc.
Some modifications to make it useful for auto-testing on win32:
- use own argv0 to find helper win32-specific subprogram
- helper subprogram and conditions changed, so testing is fully
automated instead of manually checking contents of some MessageBoxes
Redirection test checks "sort" output for locale-independent string
instead of relying on "netstat" locale-dependent string.
Also with "sort" it become usable on unix, so enabled there too.
Currently this fails on win32 with coverage since
some coverage-realted error output from gpawn-win32-helper
is unexpectedly treated as executed subprocess output.
Added test checking "sort" with error-only redirection. This also fails
on win32 by now, due to a typo in gspawn-win32.c (checks for stdout
redirection instead of stderr)
The existing singlethread g_spawn_sync test is modified and now tests
that special characters in arguments are correctly passed to child.
The test is added before spawn escaping fixing on win32
and covers the case currently broken on win32:
'trailing \ in argument containing space'.
It has different semantics from _Alignof and our G_STRUCT_OFFSET
fallback. See the comments in the diff for details.
