Previously, _kh_cancel_sub assumed that it only needed to call
_km_remove if sub did not exist in subs_hash_table. This is erroneous
because the complementary operation, _km_add_missing, can be called
from process_kqueue_notifications, in which context sub can *only* have
come from subs_hash_table.
Since _km_remove is implemented using g_slist_remove, which is
documented to be a noop if the list does not contain the element to be
removed, it is safe to call _km_remove unconditionally here.

It was suggested that the project files be moved here as we don't actually
need to go two directory layers from $(srcroot), and would help us to
standardize on things in the future across the board.
When performing the verify and building the error string there were two
possibilities of an infinite loop. The first is the missing twos-complement
to unset the bit in the filtered flags. The second is the lack of handling
G_SUBPROCESS_FLAGS_NONE which can return a valid GFlagsValue (and cannot
unset the bit since the value is zero).
This walks all known values in the GSubprocessFlags type class and check
if they are set. This has the benefit that we don't call needless functions
which walk the same table as well as avoiding mutating values to build
the error string.

Previously, this would not work, as it would result in comparing the

compare higher than other versions so it's always treated as the latest

The two known use-cases for autolaunching are:
* X-forwarding: "ssh -Y myhost myapp" resulting in a
session bus on myhost but an X server on the original host
* Legacy desktop environments on OSs without D-Bus integration:
e.g. running a single GNOME or KDE app under fvwm or something,
without a session dbus-daemon being started by either systemd,
gnome-session, or OS integration scripts analogous to Debian's
/etc/X11/Xsession.d/75dbus_dbus-launch
In either case, an X11 DISPLAY is also needed.
"dbus-launch --autolaunch" doesn't do anything useful when unable
to connect to an X11 display; this has been the case since the feature
was added in 2006, and is useful to avoid "split brain" situations in
which two processes that ought to be part of the same session end up
on separate session buses. Since dbus commit 407c111 in 2011,
libdbus hasn't even attempted to run "dbus-launch --autolaunch"
unless getenv("DISPLAY") returns non-null in the parent: this avoids
doing a relatively complicated fork-and-exec that is clearly not
going to lead to success. This commit gives GDBus the same policy.
This change was originally made to work around a race condition in
subprocess spawning (Debian bug #737380, GNOME bug #711090) but
it seems valid in its own right.
In my opinion as D-Bus maintainer, "dbus-launch --autolaunch" should
be considered to be an X11 feature, and any future D-Bus enhancements
(e.g. kdbus) or successors for X11 (e.g. Wayland, Mir) should obtain
a session bus address by other means - either a session manager
such as "systemd --user", gnome-session or Upstart, or a wrapper
for the user session like dbus-run-session(1).

gdbus-tool prints a hint about the expected arguments to a function call
in case of errors. Unfortunately, it prints this message on all errors.
I've seen this confuse users several times -- they go on tweaking the
arguments trying to get the correct type, even though they had it
correct in the first place.
Let's limit the hint to the case where it was actually invalid arguments
that triggered the problem. Also, adjust the code that prints the
message so that it will also report on the case that no arguments were
expected.
We could possibly get closer to what we want by comparing the list of
expected arguments with the parameter list, as it was parsed from the
user, but that would involve composing the expected type. Let's keep
this simple for now.

When debugging a program or testing a change to an installed version, it
is often useful to be able to replace resources in the program or a
library, without recompiling.
To support this, for debugging and hacking purposes, it's now possible
to define a G_RESOURCE_OVERLAYS environment variable as a
colon-separated list of substitutions to perform when looking up
GResources.
A substitution has the form
"/org/gtk/libgtk=/home/desrt/gtk-overlay"
The part before the '=' is the resource subpath for which the overlay
applies. The part after is a filesystem path which contains files and
subdirectories as you would like to be loaded as resources with the
equivalent names.
In the example above, if an application tried to load a resource with
the resource path '/org/gtk/libgtk/ui/gtkdialog.ui' then GResource would
check the filesystem path '/home/desrt/gtk-overlay/ui/gtkdialog.ui'. If
a file was found there, it would be used instead.
Substitutions must start with a slash, and must not have a trailing
slash before the '='. It is possible to overlay the location of a
single resource with an individual file.
https://bugzilla.gnome.org/show_bug.cgi?id=765668
Replace the hand-written equivalent of this with the call to the
GHashTable built-in version to save a few lines of code.
The GResource code was written a couple of years before this function
existed.
Similarly, replace a set-mode usage of g_hash_table_insert() with a call
to g_hash_table_add().

GContextSpecificGroup has been somewhat broken for a rather long time:
when we remove the last reference on an object held in the group, we try
to clean up the source, but fail to actually remove it from the
mainloop.
We will soon stop emitting signals on the source (due to it having been
removed from the hash table) but any "in flight" signals will still be
delivered on the source, which continues to exist. This is a problem if
the event is being delivered just as the object is being destroyed.
This also means that we leave the source attached to the mainloop
forever (and next time will create a new one)...
This is demonstrated with the GtkAppChooser dialog which writes an
update to the mimeapps.list file just as it is closing, triggering the
app info monitor to fire just as it is being destroyed.
Karl Tomlinson correctly analysed the problem and proposed this fix.

GApplication has accepted any valid bus name as an application ID since
before the time of D-Bus activation. This includes bus names with '-'.
Several applications have even attempted support bus activation with
these names, going as far as installing D-Bus service files, without
realising that they are silently falling back to fork()/exec() on
account of the name containing a dash.
The reason for the problem is that D-Bus object paths cannot contain
dashes. We solved this problem privately in an unspecified way inside
of GApplication but substituting '_' in this case, but never made this
part of the Desktop Entry Specification.
The fact that these apps with '-' in the desktop file names aren't
actually using D-Bus activation is beside the point: their intent here
was clear. Let's avoid forcing them to rename their desktop files again
by simply accepting '-' in desktop file names and munging the path in
the way that GApplication did so historically.
The new path escaping code here has been copied more or less verbatim
from GApplication's own code for the same purpose, with only the removal
of one irrelevant part.
An update to the desktop entry specification will follow.

Even though GetStartupInfo() in g_win32_run_session_bus() would
tell us that STARTF_FORCEONFEEDBACK flag is not set, it still
affects the rundll32 process for some reason.
This means that Windows WM changes mouse cursor to IDC_APPSTARTING for
a few seconds when rundll32 runs g_win32_run_session_bus(). Since
g_win32_run_session_bus() never satisfies the conditions set by
STARTF_FORCEONFEEDBACK, the busy cursor only goes away after a
timeout.
Fix this by explicitly running GetMessage(). To ensure that GetMessage()
doesn't block, post a quit message immediately before calling it.

Some applications support running in a mode where they present

Perform conversion before writing a value out of the cache into the registry,
and convert back when reading a value into the cache out of the registry.
The registry holds UTF-8 strings.
This is a flag used to understand if a key exists on the registry
and if it is readable. It makes more sense to rename it as readable
since anyway a key that does not exists anymore is a key that is
not readable.
The documentation of g_file_info_copy_into() was misleading. The
attributes are not just copied, @dest_info is also cleared at the
beginning. So any previously set attributes in @dest_info are lost.
There was a bug in gedit about this function, where some metadata were
not saved. So it might make sense to change the implementation to not
clear @dest_info, and copy one by one the attributes from @src_info to
@dest_info.

I'm tired of seeing 'No such file or directory' in the logs without
a hint as to what is actually wrong. Including the filename here
may help me tracking down a bug in the continuous infrastructure.
Visual Studio, at least the older versions, cannot use L on macros which
are defined as a constant string, plus the L must be applied to all string
literals here. This does not look nice, but this is life...
Rather than calculating it at configure time. This means it can expand
$libdir properly, and use the Make $(realpath) function rather than
invoking the non-portable `readlink -f`.
This fixes problems where `readlink` would be called on an invalid path
(due to a variable not being expanded) and would evaluate to "", which
would then cause things to be installed in the wrong place.

This reverts commit e5c752371c.
I think it is a recursion from the GUnixMountMonitor constructor, to a
GLocalFileMonitor on /etc/fstab, and into GUnixMountMonitor again, now
with a mutex already held, so it deadlocks.
https://bugzilla.gnome.org/page.cgi?id=traceparser/trace.html&trace_id=235354
That mutex in glocalfile.c:g_local_file_find_enclosing_mount() doesn't
seem necessary any more IMHO. Inside it, only 'mount' is modified, but
that's just a stack variable local to this function. When
klass->get_mount_for_mount_path is called, it's given one const
parameter and the other is unused, so they're unchanged. 'klass'
doesn't seem it could be modified either inside that function.
It doesn't recurse infinitely, but seems to work correctly and pass the
testsuite after this change.
The FreeBSD project already applied my patch in their ports tree, and
their users seem happy with it.

As g_win32_get_command_line() calls CommandLineToArgvW() to acquire the
arguments passed into a GApplication program, it actually returns the
whole command line which is used to invoke the program, including the
script interpreter and its flags when a script using GNOME bindings
(e.g. PyGObject and so on) is being invoked.
The issue here is that g_application_run() would most probably have
trouble in the scripts scenario on Windows as it is likely unable to
"recognize" the script interpreter, causing such scripts to fail to run.

Otherwise, we'll acquire it on every loop iteration, which can leave us
vulnerable to racing another thread for the acquisition of the main
context.
This can break methods like g_main_context_invoke, which try to acquire
a context to figure out if it can invoke the method synchronously or
need to defer to an idle. In these cases, it isn't guaranteed that the
invocation function will be invoked in the default main context,
e.g. the one that GApplication is holding.
This also matches what GMainLoop is doing.

Recent changes to file monitors removed the delay before events were
reported. Among other things, this caused the trash backend of gvfs to
notice trashed files sooner than before.
On noticing trashed files, the backend tries to read the info file to
discover (among other things) the original location of the file.
Unfortunately, g_local_file_trash() does a strange dance when trashing a
file. It does a loop of open(O_EXCL) in order to file an empty filename
in the trash to write an info file to, trashes the file, and only then
writes the contents of the info file. This means that at the time the
file is moved to the trash, the info file is an empty stub.
Change the order so that we write out the actual content of the info
file first. If the actual trash files then we will unlink the info file
anyway.

Previously, GLib returned text/plain for empty files.
This is important because people may want to open empty (eg:

An unintended side-effect of b6fc1df022

This commit is essentially a revert of that commit, with a different
solution: we move the special-case up a bit in the function and
hard-code it to text/plain.
This change does not exactly maintain the old behaviour: previously, a
"fast" lookup would have returned application/octet-stream on an empty

We don't need to run binaries we just built in order to successfully

This means that we don't need to check for existing, native binaries

gvfs commit b358ca "Make sure metadata is always returned by
query_writable_namespaces()" changed the
query_writable_namespaces vfunc to never return NULL, but the error
checking in g_daemon_file_query_writable_namespaces still assumes vfunc
failure implies NULL return value and GError set. This causes a memory
leak as on failure the GError will be set but the vfunc implementation
will have created its own default list so NULL will not be returned, and
the GError will never be cleared.
This commit directly checks if the GError is set to detect failures,
my_error is directly dereferenced in the error block anyway.
This also removes an unneeded call to g_file_attribute_info_new(); as
the vfunc always returns us a non-NULL GFileAttributeInfoList.

for missing locations, so the test needs to take that into
account.
This is meant for opaque, non-POSIX-like backends to indicate that the
URI is not persistent. Applications should look at
G_FILE_ATTRIBUTE_STANDARD_SYMLINK_TARGET for the persistent URI.
Examples of such backends could be a portal for letting sandboxed
applications access the file-system, or a database-backed storage like
Google Drive.
In these cases, the user visible file and folder names are different
from the real identifiers, used by the backend. So, a request to
create google-drive://user@gmail.com/foo/New\ File, would actually
lead to google-drive://user@gmail.com/foo/bar on the server even though
the user visible name is still "New File". Since the server-defined URI
is persistent and sanity-checked by the backend, it is recommended that
applications switch to it as soon as possible. Backends will try to
keep a mapping from "fake" to "real" URIs, but those are only on a
best effort basis. They might not be persistent or have the same
guarantees as the "real" URIs.

g_dbus_method_invocation_return_value(), etc, don't have GError
parameters (which makes sense since they won't usually return errors,
and there's not much you could do if they did), so in the rare case
when something does go wrong, they print a warning.
However, there is at least one situation where the warning is a bad
idea: if you are using private bus connections, and a client connects,
makes a request, and then disconnects before getting the response.
Given that there's nothing the caller can do to prevent this case from
getting hit (since the client might not disconnect until after the
call to g_dbus_method_invocation_return_value() starts) and given that
the server can never actually know for sure that the client has
received the response (it might disconnect after reading the response,
but before processing it), just kill the warning in this case.

Add a new test which checks that atomically replacing a file that
is being monitored by GFileMonitor produced the expected events.
The test can easily be expanded to cover other file monitoring
scenarios.
After the big file monitoring rewrite, we only put the IN_MOVED_FROM event
in the queue for such pairs. It matches INOTIFY_DIR_MASK and thus we call
ip_dispatch_event on it, but that function was filtering it out because
the filename in the 'from' event is the one of the temp file, not the
one we are monitoring. That name is in the 'to' event, so compare it as
well, and let the event passin that case.
There is another instance of this check in glocalfilemonitor.c, which is
corrected here as well.

exit-on-close for a DBus connection is a completely normal thing. On
a regular GNOME login, gdm retains the X server, but terminates the
session login bus and associated helpers like gnome-settings-dameon,
the a11y tools, etc.
I've seen several downstream reports of confusion as to what these
apparent error messages mean in the system log. It doesn't help
that they're so obtuse.
We're also printing them to stderr, when this is not an error.
The reason this was introduced is presumably some people were confused
as to why their process exited when the system bus did. But the
solution for that I believe is documentation, not printing stuff to
everyone's system log in normal operation.

A signal accumulator can return TRUE to continue signal emission, and
FALSE to stop signal emission. handle-local-options callbacks can return
« return a non-negative option if you have handled your options and
want to exit the process ».
Currently, g_application_handle_local_options_accumulator (the
accumulator for the handle-local-options signal) returns TRUE on
non-negative return value (ie continue signal emission), and returns
FALSE on negative return values (ie when the default option processing
should continue).
This return value seems backward as on >= 0 values, subsequent
handle-local-options callbacks could overwrite the 'exit request' from
the handler, while on < 0 values, the handle-local-options processing
could end up early if several callbacks are listening for this signal.
In particular, the default handler for this signal
(g_application_real_handle_local_options) always returns -1 and will
overwrite >= 0 return values from other handlers.
This commit inverts the check so that signal emission stops early when
one of the handle-local-options callbacks indicates it wants processing
to stop and the process to exit.

We already have start, stop and is_active methods, but turning it

This is the right thing to do for the "a session is a user-session"
model implemented in dbus 1.9.14, which is described in
<http://lists.freedesktop.org/archives/dbus/2015-January/016522.html>.
It also resembles sd-bus' behaviour, although sd-bus will only try
kdbus and XDG_RUNTIME_DIR/bus, and never runs dbus-launch.
On systems following the more traditional "a session is a login-session"
model, X_R_D/bus won't exist, so it is harmless to check for it before
falling back to X11 autolaunching. Again, this matches the behaviour
of current libdbus and sd-bus versions.
Now that we do this, g_test_dbus_unset() needs to clear XDG_RUNTIME_DIR
as well as everything else.

This only alters what happens if we specifically connect to

This matches libdbus' behaviour and the D-Bus Specification, in which

In order to maintain a logical stream of events, we need to make sure we
flush and queued change notifications before responding to any requests
for information from clients.
If we don't do this, it's possible that we emit an 'add' event that was
queued at the time of a 'DescribeAll' call _after_ the reply to that
call (which already contained the description of the new action).
In practice, this is not only logically incorrect, but it can also cause
problems. If a change to action 'state' or 'enabled' occurs after the
DescribeAll but before the signal has been dispatched, it will be
ignored because an 'add' signal is already pending. When that add
signal is sent, it will contain the correct data, but the receiver will
ignore it because it already saw the action in the DescribeAll reply.

But they aren't, anymore, so just return the standard names.
This code used to look at the SCM_CREDENTIALS and ignore every message
not from uid 0. However, when user namespaces are in use this does not
work, as if uid 0 is not mapped you get overflowuid instead. Right now
this means we ignore all messages in such user namespaces and glib
apps hang on startup.
We can't look at pids either, as pid 0 is returned for processes
outside your pid namespace.
Instead the correct approach is to look at the sending sockaddr and

Always run the full algorithm for a given mime type before considering
fallback types.
This includes considering installed applications capable of handling a
particular mimetype, even if such an app is not explicitly marked as
default, and there is a default app for a less-specific type.
Specifically, this often helps with cases of installing apps that can
handle a particular subtype of text/plain. We want to take those apps
in preference to a generic text editor, even if that editor is listed as
the default for text/plain and there is no default listed for the more
specific type.
Because of the more holistic approach taken by the algorithm, it is now

https://bugzilla.gnome.org/show_bug.cgi?id=747542
Fix a couple of issues in error handling in glib-compile-schemas.
The first problem is that, in case of repeated <summary> or
<description> tags we were still allocating a GString which was never
being freed (due to the throwing of the error resulting in immediate
termination of the parse).
The second problem is that if the repeated <summary> tag also had
attributes, we would attempt to set the GError twice.
https://bugzilla.gnome.org/show_bug.cgi?id=747542
Bug 747209 introduced an error when multiple <summary> or <description>
tags are found for a single key in a GSettings schema. This check
should have been present from the start, but it was left out because the
schema compiler doesn't include these items in the cache file. Even
still -- part of the schema compiler's job is validation, and it should
be enforcing proper syntax here.
Repeated <summary> and <description> tags are a semi-common problem when
intltool has been misconfigured in the build system of a package, but
it's possible to imagine mistakes being made by hand as well.
The idea is that these problems would be caught during the build of a
package and maintainers would be forced to fix their build systems.
An unintended side-effect of this change, however, is that the schema
compiler started ignoring already-installed schemas that contained these
problems, when rebuilding the cache. This means that the installation
of _any_ application would cause the regeneration of the entire cache,
with these already-installed applications being excluded. Without the
schema in the cache, the application would crash on next startup.
The validation check in the gsettings m4 macro passes --strict to the
compiler, which is not used when rebuilding the cache after
installation. Pass this flag down into the parser and only throw the
error in case --strict was given. This will result in the (desired)
build failure without also causing already-installed apps to stop
functioning.
This means that we will not get even a warning about the invalid schema
file in the already-installed case, but that's fine. There is no sense
spamming the user with these messages when they are already quite fatal
for the developer at build time.

Add support for copying session data between client connections.
This is needed for implementing FTP over SSL. Most servers use a separate
session for each control connection and enforce sharing of each control
connection's session between the related data connection.
Copying session data between two connections is needed for two reasons:
1) The data connection runs on a separate port and so has a different
server_identity which means it would not normally share the session with
the control connection using the session caching currently implemented.
2) It is typical to have multiple control connections, each of which
uses a different session with the same server_identity, so only one of
these sessions gets stored in the cache. If a data connection is opened,
(ignoring the port issue) it may try and reuse the wrong control
connection's session, and fail.
This operation is conceptually the same as OpenSSL's SSL_copy_session_id
operation.

operation to complete. Previously there was a workaround for this, by
bumping up the thread limit when that case was detected, but deadlocks
could still happen if there were non-GTask threads involved. (Eg, task
A sends a message to thread X and waits for a response, but thread X
needs to complete task B in a thread before returning the response to
task A.)
So, allow GTask's thread pool to be expanded dynamically, by watching
it from the glib worker thread, and growing it (at an
exponentially-decreasing rate) if too much time passes without any
tasks completing. This should solve the deadlocking problems without
causing sudden breakage in apps that assume they can queue huge
numbers of tasks at once without consequences.

This schema compiler was completely ignoring <summary> and
<description> tags. Unfortunately, there are modules out there
who merge translations for these back in, with xml:lang. And
this is giving dconf-editor a hard time. Since this is not
how translations of schemas are meant to be done, just
reject such schema files.
Also add tests exercising the new error handling.

Due to a typo, a rename reported via a pair of delete/create events (due
to the watcher not giving the flag for moves to be paired) was
accidentally reported as being created with the old name instead of the
new name.
Fix that.
We declare the typedefs for GListModel and GListStore in giotypes.h, as
a matter of convention. This is not actually required, since the
typedef is emitted as part of the G_DECLARE_* macros.
The giotypes.h approach is only used to avoid cyclic dependencies
between headers, which is not a problem in this case.
Type redefinition is a C11 feature, and although it was around in some
compilers before then, gcc 4.2.1 (from 2007) is apparently still in wide
use, being the default compiler for OpenBSD.
Eventually, we will probably hit a case where we actually need to
redefine a type, but since we're not there yet, let's back off a bit.
This WIP patch moves the Windows Directory Monitoring code to the new
GLocalFileMonitor mechanism, and adds file monitoring in the process.
Progress from previous patch:
-File renames are now properly supported, but G_FILE_MONITOR_EVENT_MOVED_IN
and G_FILE_MONITOR_EVENT_MOVED_OUT needs to be investigated, as
ReadDirectoryChangesW() seems to send FILE_ACTION_REMOVED when a file is
moved out of a directory.
-Events are handled for both the long and short (8.3) variants of the
filenames, and files monitored will report changes when it is changed
via its short or long filenames.
Things to be done:
-Perhaps find out about attribute changes in files in a monitored
directory; if a file is monitored, attribute changes are correctly
handled.
-Investigate on G_FILE_MONITOR_EVENT_MOVED_OUT,
G_FILE_MONITOR_EVENT_MOVED_IN, G_FILE_MONITOR_EVENT_PRE_UNMOUNT,
G_FILE_MONITOR_EVENT_UNMOUNTED.
-Investigate on the "boredom" algoritm, and see how we can do it on
Windows.

Completely rewrite the FAM file monitor. Major changes:
- now runs in the worker thread
- dispatches events in a threadsafe way via GFileMonitorSource
- uses unix fd source instead of a GIOChannel
- is now simple enough to fit into one short file
This is the bare minimal effort. This seems not to crash immediately,
but it definitely needs some better testing.
The backend is not in good shape. It could use some serious work.
Use the "interesting" value from g_file_monitor_source_handle_event() to
decide if we're currently being flooded by a stream of boring events.
The main case here is when one or more files is being written to and the
change events are all being rate-limited in the GFileMonitor frontends.
In that case, we become "bored" with the event stream and add a backoff
timeout. In the case that it is exactly one large file being written
(which is the common case) then leaving the event in the queue also lets
the kernel perform merging on it, so when we wake up, we will only see
the one event. Even in the case that the kernel is unable to perform
merging, the context switch overhead will be vastly reduced.
In testing, this cuts down on the number of wake ups during a large file
copy, by a couple orders of magnitude (ie: less than 1% of the number of
wake ups).
Return an "interesting" boolean from the event handler function on
GFileMonitorSource.
An event was "interesting" if it will result in a signal actually being
dispatched to the user. It is "uninteresting" if it only hit an
already-dirty rate limiter.
We will use this information to do some backing off in the backends when
faced with a flood of uninteresting events.
We generally assume that an IN_CREATE event is the start of a series of
events in which another process is doing this:
fd = creat (...) -> IN_CREATE
write (fd, ..) -> IN_MODIFY
write (fd, ..) -> IN_MODIFY
close (fd) -> IN_CLOSE_WRITE
and as such, we use the CHANGES_DONE_HINT event after CREATED in order
to show when this sequence of events has completed (ie: when we receive
IN_CLOSE_WRITE when the user closes the file).
Renaming a file into place is handled by IN_MOVED_FROM so we don't have
to worry about that.
There are many other cases, however, where a new file 'appears' in a
directory in its completed form already, and the kernel reports
IN_CREATE. Examples include mkdir, mknod, and the creation of
hardlinks. In these cases, there is no corresponding IN_CLOSE_WRITE
event and the CHANGES_DONE_HINT will have to be emitted by an arbitrary
timeout.
Try to detect some of these cases and report CHANGES_DONE_HINT
immediately.
This is not perfect. There are some cases that will not be reliably
detected. An example is if the user makes a hardlink and then
immediately deletes the original (before we can stat the new file).
Another example is if the user creates a file with O_TMPFILE. In both
of these cases, CHANGES_DONE_HINT will still eventually be delivered via
the timeout.
Remove all event merging and dispatch logic from GFileMonitor. The only
implementation of GFileMonitor outside of glib is in gvfs and it already
does these things properly.
Get rid of GLocalDirectoryMonitor. We will use a single class,
GLocalFileMonitor, for both directory and file monitoring. This will
prevent every single backend from having to create two objects
separately (eg: ginotifydirectorymonitor.c and ginotifyfilemonitor.c).
Introduce GFileMonitorSource as a thread-safe cross-context dispatch
mechanism. Put it in GLocalFileMonitor. All backends will be expected
to dispatch via the source and not touch the GFileMonitor object at all
from the worker thread.
Remove all construct properties from GLocalFileMonitor and remove the
"context" construct property from GFileMonitor. All backends must now
get the information about what file to monitor from the ->start() call
which is mandatory to implement.
Remove the implementation of rate limiting in GFileMonitor and add an
implementation in GLocalFileMonitor. gvfs never did anything with this
anyway, but if it wanted to, it would have to implement it for itself.
This was done in order to get the rate_limit field into the
GFileMonitorSource so that it could be safely accessed from the worker
thread.
Expose g_local_file_is_remote() internally for NFS detection.
With the "is_remote" functionality exposed, we can now move all
functions for creating local file monitors to a proper location in
glocalfilemonitor.c
Port the inotify backend to adjust to the changes above. None of the
other backends are ported yet. Those will come in future commits.
Remove the hardwired 1 second event queue logic from inotify-kernel and
replace it with something vastly less complicated.
Events are now reported as soon as is possible instead of after a
delay.
We still must delay IN_MOVED_FROM events in order to look for the
matching IN_MOVED_TO events, and since we want to report events in order
this means that events behind those events can also be delayed. We
limit ourselves, however:
- no more than 100 events can be delayed at a time
- no event can be delayed by more than 10ms
https://bugzilla.gnome.org/show_bug.cgi?id=627285
Add a new internal constructor for GLocalFile (which itself is private).
This new constructor allows creating a GLocalFile from a dirname and a
basename, assuming that the dirname is already in canonical form and the
basename is a regular basename.
This will be used for creating GLocalFile instances from the file
monitoring code (for signal emissions).
For all of the effort spent ensuring that this algorithm would be
correctly threadsafe, I messed up the order of operations within a
single thread when porting to the new approach.
Fix that up.
Also: fix some overzealous asserting in the testcases. Since shutdown
is now lazy, we can never surely say !is_running at any particular point
in time.
This can be used to query whether the task has completed, in the sense
that it has had a result set on it, and has already – or will soon –
invoke its callback function.
Notifications for this property are emitted immediately after the task’s
main callback, in the same main context as that callback. This allows
for multiple bits of code to listen for completion of the GTask, which
opens the door for blocking on cancellation of the GTask and improved
handling of ‘pending’ behaviour.

Currently, the Windows code use Winsock2-specific APIs to try to emulate
calls such as inet_pton(), inet_ntop() and if_nametoindex(), which may not
do the job all the time. On Vista and later, Winsock2 does provide a
proper implementation for these functions, so we can use them if they exist
on the system, by querying for them during g_networking_init(). Otherwise,
we continue to use the original code path for these, in the case of XP and
Server 2003.
This enables many of the network-address tests to pass on Windows as a
result, when the native Winsock2 implementations can be used.

There was a theoretical deadlock between the worker trying to emit a
signal at the same time as we were waiting for it to shutdown the
notification (while holding the lock).
The deadlock was particularly annoying because we didn't really need to
wait for the shutdown and because it wasn't possible to signals to
arrive while waiting for a start. Attempting to deal with start and
stop in an asymmetric way could have lead to other weird situations,
however.
Drop the lock while waiting for the worker thread to start. This means
that we face the possibility of multiple waiters on the cond at the same
time, so we need to make more of a state machine.

GUnixMountMonitor was not threadsafe before. It was a global singleton
which emitted signals in the first thread that happened to construct it.

Deprecate g_unix_mount_monitor_set_rate_limit() and turn it into a

This function doesn't behave as advertised. It only controls rate
limiting for filesystem-based monitors. It has no impact over reporting
mount changes on Linux, for example, because those are based on polling
for changes in /proc (which doesn't use filesystem monitors). It also
has no impact on Mac OS because a library interface is used there.
This was added in https://bugzilla.gnome.org/show_bug.cgi?id=521946 in

Add an implementation of non-thread-emulated async close of a GIOStream

GApplication set the prgname to the application's id when it was running
in service mode. This broke with the addition of new --app-id option,
because g_set_prgname() was called before parsing the options. Calling
it after option parsing doesn't work, because GOptionContext sets
prgname to argv[0] unconditionally.
Instead of changing the semantics of GOptionContext, simply remove this
functionality from GApplication. It is very unusual to have the prgname
set to the app id instead of the binary's name and might confuse people
when looking at logs etc.
When overriding local_command_line() from a subclass,
g_option_context_parse() might never be invokded. Thus, continue setting

Make sure that we only match the _get_type() function name by

the default rule of '*' being greedy).
This affected G_DECLARE_*_TYPE which puts several uses of _get_type()

When implementing blocking operations on top of
nonblocking sockets we should always first try to
perform the operation and then if needed handle
EAGAIN and wait with g_socket_wait_condition.
This is an optimization since we avoid calling
wait condition when it is not needed, but most
importantly this fixes hangs on win32 where some
events (in particular FD_WRITE) are only emitted
after the operation fails with EWOULDBLOCK.

Add a unit test that checks g_socket_new_from_fd by creating
a gsocket, obtaining its fd, duplicating the fd and then creating
a gsocket from the new fd. This shows a hang on win32 since the

because we wait for the condition without first trying to write
and windows signals the condition only after a EWOULDBLOCK error.

Fix two problems:
1) If g_socket_service_stop is called before the accept call is requeued,
then the reference count won't decrease and this code will hang forever:
while (G_OBJECT (service)->ref_count == ref_count)
g_main_context_iteration (NULL, TRUE);
2) Sometimes the testcase fails (maybe 1 in 200 times for me):
GLib-GIO:ERROR:socket-listener.c:73:connection_cb: assertion failed
(G_OBJECT (service)->ref_count == 2): (3 == 2)
Aborted (core dumped)
The problem is that depending on ordering, cancellation of the async
listener can require further main context iterations before it releases
the reference on the socket service. Furthermore, in some cases, it
requires at least one iteration.

It doesn't really make sense to try to distinguish EPIPE and
ECONNRESET at the GLib level, since the exact choice of which error
gets returned in what conditions depends on the OS. Given that, we
ought to map the two errors to the same value, and since we're already
mapping EPIPE to G_IO_ERROR_BROKEN_PIPE, we need to map ECONNRESET to
that too. But the existing name doesn't really make sense for sockets,
so we add a new name.

This is a convenience method for creating a GNetworkAddress which is
guaranteed to return IPv4 and IPv6 loopback addresses. The program
cannot guarantee that 'localhost' will resolve to both types of
address, so programs which wish to connect to a local service over
either IPv4 or IPv6 must currently manually create an IPv4 and another
IPv6 socket, and detect which of the two are working. This new API
allows the existing GSocketConnectable machinery to be used to
automate that.

g_settings_has_signal_handlers() checks whether any of the signals has

Add a GSocketListener test program. Currently the only test is a
regression test for bug 712570 (based on a standalone bug reproducer

If all users of a GThreadedSocketService release their references to the
service while a connection thread is running, the thread function will
release the last reference to the service which causes the finalize to
deadlock waiting for all threads to finish (because it's called from the
thread function).
To fix this, don't wait for all threads to finish in the service's
finalize method. Since the threads hold a reference to the service,
finalize should only be called when all threads are finished running (or
have unrefed the service and are about to finish).

If SSL 3.0 has been disabled (at the host, application, or library
level), then the "use-ssl3" property becomes a "fail-immediately"
property.
Despite the name, the point of the property wasn't really specifically
to use SSL 3.0; it was to allow fallback when talking to broken
servers that do SSL/TLS negotiation incorrectly and break when they
see unexpectedly-high version numbers. So if we can't fall back to SSL
3.0, then the "use-ssl3" property should fall back to TLS 1.0 instead
(since there are hosts that will reject a TLS 1.2 handshake, but
accept a TLS 1.0 one).

the documentation here.

In commit 8ff5668, we are subscribing the GSettings backend later, but this
meant that we need to initialize cache_lock earlier, as we might try to
use that lock before a change notification is issued to subscribe the
backend, which would then cause an access violation if we are trying to
read GSettings values, as that lock is used to access the Windows Registry.
Initialize cache_lock once we initialize the GSettings Registry backend,
and delete it upon finalize, so that g_settings_read_from_backend() can
proceed normally, even if the GSettings backend is not yet subscribed.

GSettings objects begin watching for changes as soon as they are created
in order that they can emit the "changed" signal.
In the case of dconf, if we want to be able to emit the changed signal,
we need to go on the bus and add some match rules. This requires
creating the dconf helper thread and also requires initialising GDBus
(which creates another thread).
Some users of GSettings are never interested in the "changed" signal.
One of these users is the glib-networking code that gets run every time
a new network connection is created.
Some users are reporting that they are annoyed that simply establishing
a network connection would spawn two extra threads and create a D-Bus
connection.
In order to avoid doing unnecessary work for these simple uses, delay
the subscription until we know that we will actually need to do it.
We do this in a simple way, using a simple argument: in order for the
user to care that a value changed then they must have:
1) watched for a change signal; and then
2) actually read a value
If the user didn't actually read a value then they cannot possibly be
interested in if the value changed or not (since they never knew the old
value to begin with and therefore would be unable to observe that it
ever changed, since they have nothing to compare the new value with).
This really is a behaviour change, however, and it does impact at least
one user: the 'monitor' functionality of the GSettings commandline tool,
which is interested in reporting changes without ever having known the
original values. We add a workaround to the commandline tool in order
to ensure that it continues to function properly.
It's also possible to argue that it is completely valid to have read a
value and _then_ established a change signal connection under the
(correct) assumption that it would not have been possible to miss a
change signal by virtue of not having returned to the mainloop.
Although this argument is true, this pattern is extremely non-idiomatic,
and the problem is easily avoided by doing things in the usual order.
We never really talked about change notification in the overview
documentation for GSettings, so it seems like now is a good time to add
some discussion, including the new rules for when one can expect change
signals to be emitted.

There are two consistent interpretations that could be taken for memory
handling of the 'invocation' parameter passed to the method_call() virtual
function of GDBusInterfaceVTable
- A reference is passed (transfer full) to the method_call() virtual function,
and that reference is then passed (transfer full) to the return_value/error
functions on GDBusMethodInvocation.
- An internal reference is retained from the point where method_call() is called
until the return_value/error function is called.
Since the return_value/error functions were already marked (transfer full),
we use the first interpretation, annotate the invocation parameter of
method call as (transfer full) and describe this in the documentation, along
with the idea that you are always supposed to call one of the return_value/error

See bug 738122 for the leak this caused in GJS.

Clarify in the documentation that a GSource created with
g_cancellable_source_new() must be explicitly removed from its
GMainContext before the GCancellable can be finalised.
This could be a common way of leaking GCancellables.

da053e34 broke the tls-certificates test by requiring the backend to
implement g_tls_certificate_verify() (which the test TLS backend
didn't). Add a trivial implementation to make the test pass again;
we'll need something more complicated when we add tests that are
supposed to get errors.
So shortcut it.
I wrote this patch less as a performance optimization and more as a
clarification, so that people looking at the code can be assured of this
invariant.

These functions are inconsistent with our normal conventions in that
they set an output variable to a specified value, even in the case that
an error is thrown.
Document very clearly that this should be considered exceptional.

Similar to the previous patch, this commit contains a minor violation of
normal API conventions. See the explanation in the previous commit
message.
Heavily based on a patch from Ignacio Casal Quinteiro.

Add an asynchronous version of _read_all().
This API is not fully consistent with the normal expectations of a
non-asynchronous version. Consistency between the sync and async version is
probably more important.
The API will still bind correctly, but access to all functionality will
not be available: specifically, in the case of an error, higher level
languages will be unable to determine how many bytes were successfully
read before the error. Most users will probably not want to use this
information anyway, so this is OK -- and if they do need the
information, then they can just write the loop for themselves.

Commit e24e89b accidentally ironically introduced a typo when replacing
the code with symbolic contents. Specifically, "Added Associations" was
replaced with "Default Applications" when reading defaults.list, giving
a warning about the file containing a "Default Applications" group.
If this was intended, it should have not been lumped in with a cleanup.
This patch changes the behavior of the following functions:
g_tls_certificate_new_from_pem
g_tls_certificate_new_from_file
g_tls_certificate_new_from_files
If more than one certificate is found it will try to load the chain.
It is assumed that the chain will be in the right order (top-level
certificate will be the last one in the file). If the chain cannot be
verified, the first certificate in the file will be returned as before.

g_thread_pool_push() only returns an error if it fails to spawn a new
thread. However, it unconditionally adds the task to its worker queue,
so:
• if _any_ threads exist in the pool, the task will eventually be
handled; and
• if _no_ threads exist in the pool, the task will be handled if one
is eventually successfully spawned.
If no more threads are ever spawned, the process probably has bigger
problems than a single GTask which is taking forever to complete.

For the GPtrArray example, several variables declared on the same line
is harder to read and to work with (to move, remove or comment a single
variable declaration).
Some desktop file directories, like /usr/local/share/applications may be
missing on some systems.
When we try to inotify on these directories, this will result in a
every-4-seconds poll being setup which is quite bad.
This is an issue that should be fixed in inotify itself but the problem
is much larger there. For now, we can work around it in GDesktopAppInfo
by refusing to monitor missing directories.
We may get some spurious notifications of changes in the case that
/usr/local/share or /usr/local/share/applications is created without
actually adding desktop files, but spurious changes can already be
reported in other cases, so that's OK. We won't get (user-visible)
notification for a simple case of a completely unrelated file being
created (however we cannot avoid the wakeup in this case due to how
inotify works). That's probably pretty theoretical, though, since files
in /usr don't change much and for the home directory we're likely to
have at least ~/.config and ~/.local existing.

We use "tweaks" structures to track how a particular directory impacts
the list of added, removed and default applications. We maintain this
set of tweaks for each directory, in a hash table, keyed by unaliased
mime type name, in order to facilitate fast lookups.
A typo in the logic for creating and maintaining the uniqueness of these
structures was causing the default app to be selected incorrectly from
time to time. Fix that.
