When we are in a sandboxed situation, bump the priority
of the keyfile settings backend above the dconf one,
so we use a keyfile inside the sandbox instead of requiring
holes in the sandbox for dconf.
Stacked databases and locks are dconf features that allow
management software like Fleet Commander to set system-wide
defaults and overrides centrally for applications.
This patch adds minimal support for the same to the keyfile
backend. We look for a keyfile named 'defaults' and a
lock-list named 'locks'.
Suitable files can be produced from a dconf database with
dconf dump and dconf list-locks, respectively.
The default location for these files is /etc/glib-2.0/settings/.
For test purposes, this can be overwritten with the
GSETTINGS_DEFAULTS_DIR environment variable.
Writes always go to the per-user keyfile.
Make it possible to instantiate a keyfile settings backend
without specifying parameters, by turning the arguments to
the new() function into construct-only properties. If no
filename is specified, default to
$XDG_CONFIG_HOME/glib-2.0/settings/keyfile
It needs investigating and fixing properly, but let’s not let it disrupt

There's a race here, as revealed by Debian's buildds.
We call g_dbus_proxy_new() to create a proxy for the test server, with
callback proxy_ready() Then we call g_spawn_command_line_async() to
start the test server, and then start the main loop.
proxy_ready() assumes that the test server hasn't been started when it
is called. But there is no guarantee that these asynchronous operations
involving spawning a process won't happen in a different order that mean
the bus name *does* have an owner.
What we can do is move starting the server inside of proxy_ready(), so
we know that the test server isn't started until after the proxy is
created. We also add an assertion to check that it is indeed not running
before we execute it.
Rather than storing it as an invalid value in last_position, store it as
a separate boolean.
This introduces no functional changes, but should fix some warnings from
MSVC.

Like for the OpenURI portal, O_PATH file descriptors do not prove access
to the underlying file data. I've used O_RDWR file descriptors here to
mirror the requested read/write permissions.
This change relates to https://github.com/flatpak/xdg-desktop-portal/issues/167
The OpenURI portal requires the caller to pass a file descriptor as
proof of access for local files. Old versions required this file
descriptor to use the O_PATH mode. However, this does not prove access
since you can create O_PATH descriptors for files that you can't read.
Since xdg-desktop-portal 1.0.1, regular file descriptors are also
accepted with O_PATH descriptors restricted to flatpaks for the
transition.
Check for over- and underflow when manipulating positions.
This makes the sequence

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.

The appinfo-test.desktop file is set up with an Exec= path which points
to the compiled and installed appinfo-test utility. When running the
tests uninstalled, however, this might not be present, which causes
loading appinfo-test.desktop to fail.
Split appinfo-test.desktop in two: keep the existing
appinfo-test.desktop for tests which need to launch appinfo-test, and
add a new appinfo-test-static.desktop for tests which don’t launch
anything (and, for example, just inspect GAppInfo properties).
appinfo-test-static.desktop uses an Exec= line which should always be
present (`true`) so it should never fail to load.
Allow the tests using appinfo-test-static.desktop to be run uninstalled
or installed. Allow the tests using appinfo-test.desktop to be skipped
if loading appinfo-test.desktop fails, which is an indicator that the
test is running uninstalled.

This partially reverts commit 799f8dcd46.
This patch seems to break the writability status of the server socket: once
somebody writes to it with success, then it reports it is not writable
anymore. Also, when the client socket has the flag FD_CONNECT set once,
it is never cleared and then it reports it is always writable, also when
it is not.
This checks if the stream is writable before writing
to it. If the write succeeded with no error, then the
stream has to be also writable after the write
Currently a new connection will not be attempted until the previous
one has timed out and as the current API only exposes a single
timeout value in practice it often means that it will wait 30 seconds
(or forever with 0 (the default)) on each connection.
This is unacceptable so we are now trying to follow the behavior
RFC 8305 recommends by making multiple connection attempts if
the connection takes longer than 250ms. The first connection
to make it to completion then wins.
As RFC 8305 recommends we can start multiple DNS queries in parallel
to more quickly make an initial response, especially when one is
particularly slow/broken.
This allows higher levels to have more control over resolving
(ipv4 or ipv6 for now) which allows for optimizations such
as requesting both in parallel as RFC 8305 recommends.
This means the output (including lists of filenames) does not depend on
the order of the input files, which may matter if this tool is invoked
with a glob or some other mechanism that doesn't guarantee an order.
Turns out the fix in commit 93555577c wasn't enough, when using glib as
subproject and the parent project uses only libgio_dep, and include
<gi18n.h>, it won't find libintl.h because it's in the
include_directories of libglib_dep. Fix that by declaring dependencies
explicitly, which is the right thing to do since glib and gobject are
public dependencies of gio. That reflects what we do for the pkg-config
file as well.
Previously, method and signal arguments were sorted by name, which
(assuming you don't happen to give your arguments
lexicographically-ordered names) means the generated signatures were
incorrect when there is more than 1 argument.
While sorting the methods and signals themselves (and properties, and
annotations on all these) is fine, it's easiest to not sort anything.

glib-compile-resources was updated to generate octal byte
representation in a string, but unfortunately this breaks the build
on Visual Studio when the generated string sequence exceeds 65535
characters, which is the imposed limit on Visual Studio compilers.
To make things work on Visual Studio builds and to not slow down things
on other compilers, generate a code path for Visual Studio an array of
octal byte representations, as well as a code path for other compilers
that use the new string representation of octal values, and let the
compiler take the appropriate code path when compiling the
generated code.
Fixes issue #1580.
While uniqueness is great, sometimes you want to restart

When using glib as subproject we are forced to pass glib_dep,
gobject_dep and gio_dep to any build target. If we pass only gio_dep it

Allowing unsafe rehandshakes used to be required for web compatibility,
but this is no longer a concern in 2018. So there should no longer be
compatibility benefits to calling this function. All it does is make
your TLS connection insecure.
Also, rehandshaking no longer exists at all in TLS 1.3.
At some point (maybe soon!) glib-networking will begin ignoring the
rehandshake mode, so let's deprecate it now.
Let's entirely deprecate calling this function for rehandshaking. The
current documentation is OK, but guarantees defined behavior (to attempt
a rehandshake) when TLS 1.2 is in use. But there's no way to force TLS
1.2, and also no way to check which version of TLS is in use. I really
should have deprecated use of this function for rehandshaking entirely
last time I updated it.
Fortunately, there should be no compatibility risk for existing code,
because rehandshaking has no visible effects at the API level.
With the changes to limit GVariant type nesting (commit 7c4e6e9fbe),
it’s now possible to have a valid type signature which is not a valid

This test is intended to verify the fix for
https://bugzilla.gnome.org/show_bug.cgi?id=787731, which was that
g_file_query_filesystem_info() would return stale information for the
mount. After replacing a read-only mount with a read-write mount, this
test used to only fail if G_FILE_ATTRIBUTE_FILESYSTEM_READONLY was TRUE
and yet the file could be opened for writing. In particular, if (due to
a test bug) the file really was still on a read-only filesystem, the
test would pass.
Now that we have fixed that bug in the test, we can make a stronger
assertion.
fusermount -z behaves like umount --lazy, which is documented thus:
> Detach the filesystem from the file hierarchy now, and clean up all
> references to this filesystem as soon as it is not busy anymore.
Without this, the call to `fusermount -u` often fails with:
/usr/bin/fusermount: failed to unmount /home/wjt/src/gnome/glib/_build/dir_bindfs_mountpoint: Device or resource busy
which causes the subsequent call to bindfs to fail:
fuse: mountpoint is not empty
fuse: if you are sure this is safe, use the 'nonempty' mount option
It's not clear what is causing the mount to be busy. Inserting a
g_usleep (100 * 1000) before the calls to `fusermount -u` also works to
make the problem go away, but for the purposes of this test the
important point is that the mount is detached from the directory, for
which a lazy unmount is fine.
Fixes#1590.
In practice, fusermount -u often fails:
/usr/bin/fusermount: failed to unmount /home/wjt/src/gnome/glib/_build/dir_bindfs_mountpoint: Device or resource busy
which causes the subsequent calls to bindfs to fail:
fuse: mountpoint is not empty
fuse: if you are sure this is safe, use the 'nonempty' mount option
This may or may not cause the current test run to fail, but it reliably
causes a repeat run of the test to fail. This change causes the current
run to fail instead.
I made a mistake when last updating the documentation in 94a99ae9. I
wrote that, with TLS 1.3, this would perform a rekey instead of a
rehandshake. In fact, that's only true for client connections. For
server connections, it's a no-op.
I was a bit nervous about how to document the behavior anyway, because
we really don't know what behavior will be reasonable with non-GnuTLS
crypto backends. This behavior is reasonable for the GnuTLS backend, but
might not necessarily make sense for OpenSSL. Ideally, we would
discourage API users from doing things which could have unexpected
effects, so instead of documenting what the GnuTLS backend does, I think
it'd be better to document that this is "undefined but not dangerous,"
since of course we want to make sure that existing code that doesn't
know about TLS 1.3 is not broken.
The docs sound like settings list is a thing, and
a ::children-changed signal exists. That is not the
case, and will never be the case at this point, so
stop pretending.
Closes: #1362
