spec: Clarify behaviour of o.f.D.P.GetAll

Clarify its intended behaviour in two situations:
 • For interfaces which have no properties.
 • Where some properties are not visible to the caller (due to access
   control, for example).

The intention here is for this behaviour to be mandatory, but given that
this is quite late on in the specification’s life, and various D-Bus
libraries like dbus-glib and telepathy-glib cannot support access
control at a per-property level, for example. GDBus can, although it’s
questionable whether this is a good idea. Deliberately leave the
specification open to allow access control at a higher level as well

Be more const-correct

As a general design principle, strings that we aren't going to modify

string constants are of type "const char *", causing compiler warnings

Unfortunately, we need to add casts in a few places:

* _dbus_list_append(), _dbus_test_oom_handling() and similar generic
  "user-data" APIs take a void *, not a const void *, so we have
  to cast
* For historical reasons the execve() family of functions take a
  (char * const *), i.e. a constant pointer to an array of mutable
  strings, so again we have to cast
* _dbus_spawn_async_with_babysitter similarly takes a char **,
  although we can make it a little more const-correct by making it
  take (char * const *) like execve() does

This also incorporates a subsequent patch by Thomas Zimmermann to

8 years agoRename distro-style CI build from "release" to "production"
Simon McVittie [Sat, 1 Oct 2016 14:20:11 +0000 (15:20 +0100)]
Rename distro-style CI build from "release" to "production"

This avoids confusion with the meaning of "release" used by
AX_IS_RELEASE. AX_IS_RELEASE is about facts about the source tree,
namely the distinction between releases (tags) and random snapshots.
The build variants in .travis.yml are about facts about the build
being done, namely the distinction between production and
debug/developer builds.

Production builds are sometimes referred to as "release builds",
for example in typical CMake and MSVC build environments, but a
different term seems better here.

DBusMessage: Fix UB (misaligned access) in call to _dbus_header_set_field_basic()

The const void* 'value' pointer that is passed the address of a
uint32_t here eventually ends up in _dbus_marshal_write_basic(), which
casts it to a DBusBasicValue, a union type that has an alignment of

The read of a value of a more-aligned type through a pointer to a less

8 years ago_dbus_warn, _dbus_warn_check_failed: unify with _dbus_logv
Simon McVittie [Wed, 20 Jul 2016 08:25:57 +0000 (09:25 +0100)]
_dbus_warn, _dbus_warn_check_failed: unify with _dbus_logv

This means that dbus-daemon will log something like

    dbus-daemon[123]: Unable to add reload watch to main loop

to syslog and/or stderr according to its configuration, while other
libdbus users will print something like this to stderr:

    dbus[4567]: arguments to dbus_foo() were incorrect, assertion
    "connection != NULL" failed at file dbus-foo.c line 123.
    This is normally a bug in some application using the D-Bus library.

This slightly changes the meaning of the argument to _dbus_warn()
and _dbus_warn_check_failed. Previously, a trailing newline was
expected, and a missing newline would have resulted in incorrect
output. Now, a newline is supplied automatically by the
library (like g_warning()), and messages that end with a newline will
result in an unnecessary extra newline in output.

This extra newline is harmless, so I'm not going to change all the
callers immediately.

8 years ago_dbus_logv: configurably log to syslog and/or stderr
Simon McVittie [Fri, 12 Aug 2016 16:59:45 +0000 (17:59 +0100)]
_dbus_logv: configurably log to syslog and/or stderr

This changes the behaviour of _dbus_logv() if _dbus_init_system_log() was
not called. Previously, _dbus_logv() would always log to syslog;
additionally, it would log to stderr, unless the process is dbus-daemon
and it was started by systemd. Now, it will log to stderr only,
unless _dbus_init_system_log() was called first.

This is the desired behaviour because when we hook up
_dbus_warn_check_failed() to _dbus_logv() in the next commit, we don't
want typical users of libdbus to start logging their check failures to
syslog - we only want the dbus-daemon to do that.

In practice this is not usually a behaviour change, because there was
only one situation in which we called _dbus_logv() without first calling
_dbus_init_system_log(), namely an error while parsing configuration
files. Initialize the system log "just in time" in that situation
to preserve existing behaviour.
