This is a much simpler way to display simple message-box type dialogs,
whose absence I've previously been working around by laboriously
constructing something in my usual style.
We were using it in the main config box to ensure everything expanded
on window resize, but in GTK3 that's the default anyway. And we were
using it to put padding around the edges of the font selector, which
is now done using the "margin" property.
Using GTK to run on OS X is going to require several workarounds and
behaviour tweaks to be enabled at various points in the code, and it's
already getting cumbersome to remember what they all are to put on the
command line. Here's a central #define (OSX_GTK) that enables them all
in one go, and a configure option (--with-quartz) that sets it.
As part of this commit, I've also rearranged the #include order in the
GTK source files, so that they include unix.h (which now might be
where NOT_X_WINDOWS gets defined) before they test NOT_X_WINDOWS to
decide whether to include X11 headers.
In shortcut_add(), when we add an underlined letter to a GtkLabel, we
were fetching the label's height before changing its text, and
restoring it afterwards. I've no idea why - I can see no difference
with and without the code.
That code's been there since 2003 without explanation. My best guess
is that it was working around a GTK bug of the day, but since no
difference is visible even in current GTK1, I think I'm just going to
remove it. If any problems show up later, I can put it back, with an
actual comment!
The whole of get_label_text_dimensions() should have been outside the
GTK 2 ifdef; I'd left a gtk_label_set_width_chars() unconditional; and
GDK1's gdk_window_set_background() lacks a const in its prototype.
Serves me right for not test-compiling in all three versions!
My trickery in GTK2 to start with some branches of the tree collapsed
but give the widget all the width it will need when they open later
was not working in GTK3, for the same reason I've needed several other
fixes recently: just after creation, GTK3 widgets report their
preferred size as zero.
Fixed by doing basically the same trick I was doing in GTK2, but
deferring it until the "map" event happens later on.
This was another piece of code that determined text size by
instantiating a GtkLabel and asking for its size, which I had to fix
in gtkfont.c recently because that strategy doesn't work in GTK3.
Replaced the implementation of string_width() with a call to the
function I added in gtkfont.c, and now dialog boxes which depend on
that for their width measurement (e.g. the one in reallyclose()) don't
come out in silly sizes on GTK3 any more.
In cases where two controls sit alongside one another such as a label
alongside an edit box, I've previously been arranging for them to be
vertically centred by fiddling with the size request and alignment of
what I assume will be the shorter control. But now I've written
columns_force_same_height(), that's a much easier approach, and it's
also compatible with GTK3 without using a deprecated method; so this
change switches over all vertical centring to doing it that way.
Also, while I'm here, I noticed that the edit box and button of
CTRL_FILESELECT / CTRL_FONTSELECT were not vertically centred, and
since it's now really easy to make sure they are, I've added another
use of columns_force_same_height() there.
This replaces the old GtkColorSelectionDialog, and has the convenience
advantage that the actual chooser (with all the 'set colour', 'get
colour' methods) and the containing dialog box are now the same object
implementing multiple interfaces, so I don't keep having to call 'get
me the underlying chooser for this dialog' accessors. Also you now
hook into both the OK and Cancel buttons (and all other response
codes) at the same time with a single event.
The config box setup code wants a lot of very narrow edit boxes, so it
decreases their minimum width from the GTK default of 150 pixels. In
GTK 3, we have to do this using gtk_entry_set_width_chars() rather
than gtk_widget_set_size_request() as we were previously using, or it
won't work.
This change by itself seems to restore the GTK3 config box to a
sensible layout, in spite of the fact that my Columns layout class is
still doing all its size allocation the GTK2 way, with no attention
paid to the shiny new GTK3 height-for-width system.
GTK 2 has deprecated it and provided no replacement; a bug tracker
entry I found on the subject suggested that it was functionality that
didn't really belong in GTK, and glib ought to provide a replacement
instead, which would be a perfectly fine thing to suggest if they had
waited for glib to get round to doing so *before* throwing out a
function people were actually using. Sigh.
Anyway, it turns out that subsidiary invocations of gtk_main() don't
happen inside GTK as far as I can see, so all I need to do is to make
sure my own invocations of gtk_main() are followed by a cleanup
function which runs any quit functions that I've registered.
That was the last deprecated GTK function, so we now build cleanly
with -DGTK_DISABLE_DEPRECATED. (But, as mentioned a couple of commits
ago, we still don't build with -DGDK_DISABLE_DEPRECATED, because that
has migrating to Cairo drawing as a prerequisite.)
Now that I've got a general place to centralise handling of at least
the simple differences between GTK 1 and 2, I should use it wherever
possible. So this commit removes just a small number of ifdefs which
are either obsoleted by definitions already in gtkcompat.h (like
set_size_request vs set_usize), or can easily be replaced by adding
another (e.g. gtk_color_selection_set_has_opacity_control).
Building with -DGTK_DISABLE_DEPRECATED, we now suffer only one compile
failure, for the use of gtk_quit_add() in idle_toplevel_callback_func.
That function is apparently removed with no replacement in GTK 3, so
I'll need to find a completely different approach to getting toplevel
callbacks to run only in the outermost instance of gtk_main().
Also, this change doesn't do anything about the use of *GDK*
deprecated functions, because those include the entire family of
old-style drawing functions - i.e. the only way to build cleanly with
-DGDK_DISABLE_DEPRECATED will be to switch to Cairo drawing.
I've put in a special #define to control this selection, in case I
decide that for reasons of taste I'd prefer to switch back to
GtkFileSelection in GTK2 which supports both!
Replaces the deprecated gtk_color_selection_set_color() which took an
array of four doubles (RGBA), and instead takes a 'GdkColor' struct
containing four 16-bit integers.
For GTK1, we still have to retain the original version.
All the things like GtkType, GtkObject, gtk_signal_connect and so on
should now consistently have the new-style glib names like GType,
GObject, g_signal_connect, etc.
A major aim of introducing GTK 3 support is to permit compiling for
non-X11 platforms that GTK 3 supports, so I'm going to need to be able
to build as a pure GTK application with no use of X11 internals.
Naturally, I don't intend to stop supporting the hybrid GTK+X11 mode
in which X server-side bitmap fonts are available.
Use of X11 can be removed by compiling with -DNOT_X_WINDOWS. That's
the same compatibility flag that was already used by the unfinished OS
X port to disable the X-specific parts of uxpty.c; now it just applies
to more source files.
(There's no 'configure' option to set this flag at present. I haven't
worked out whether we'll need one yet.)
GTK 2 doesn't _documentedly_ provide a helpful compile option to let
us check this one in advance of GTK 3, but you can fake one anyway by
compiling with -D__GDK_KEYSYMS_COMPAT_H__, so that gdkkeysyms-compat.h
will believe that it's already been included :-) We now build cleanly
under GTK 2 with that predefine.
This is the first of several cleanup steps recommended by the GTK 2->3
migration guide.
I intend to begin work towards compatibility with GTK 3, but without
breaking GTK 2 and even GTK 1 compatibility in the process; GTK 2 is
still useful to _me_ (not least because it permits much easier support
of old-style server-side X11 fonts), and I recall hearing a rumour
that at least one kind of strange system can only run GTK 1, so for
the moment I don't intend to stop supporting either.
Including gdkkeysyms.h is not optional in GTK 2, because gdk.h does
not include it. In GTK 3 it does, so we don't explicitly reinclude it
ourselves.
We now build cleanly in GTK2 with -DGTK_DISABLE_SINGLE_INCLUDES. (But
that doesn't say much, because we did already! Apparently gdkkeysyms.h
was a special case which that #define didn't forbid.)
Having found a lot of unfixed constness issues in recent development,
I thought perhaps it was time to get proactive, so I compiled the
whole codebase with -Wwrite-strings. That turned up a huge load of
const problems, which I've fixed in this commit: the Unix build now
goes cleanly through with -Wwrite-strings, and the Windows build is as
close as I could get it (there are some lingering issues due to
occasional Windows API functions like AcquireCredentialsHandle not
having the right constness).
Notable fallout beyond the purely mechanical changing of types:
- the stuff saved by cmdline_save_param() is now explicitly
dupstr()ed, and freed in cmdline_run_saved.
- I couldn't make both string arguments to cmdline_process_param()
const, because it intentionally writes to one of them in the case
where it's the argument to -pw (in the vain hope of being at least
slightly friendly to 'ps'), so elsewhere I had to temporarily
dupstr() something for the sake of passing it to that function
- I had to invent a silly parallel version of const_cmp() so I could
pass const string literals in to lookup functions.
- stripslashes() in pscp.c and psftp.c has the annoying strchr nature
All the name strings in ssh_cipher, ssh_mac, ssh_hash, ssh_signkey
point to compile-time string literals, hence should obviously be const
char *.
Most of these const-correctness patches are just a mechanical job of
adding a 'const' in the one place you need it right now, and then
chasing the implications through the code adding further consts until
it compiles. But this one has actually shown up a bug: the 'algorithm'
output parameter in ssh2_userkey_loadpub was sometimes returning a
pointer to a string literal, and sometimes a pointer to dynamically
allocated memory, so callers were forced to either sometimes leak
memory or sometimes free a bad thing. Now it's consistently
dynamically allocated, and should be freed everywhere too.
The last use of it, to store the contents of the saved session name
edit box, was removed nearly two years ago in svn r9923 and replaced
by ctrl_alloc_with_free. The mechanism has been unused ever since
then, and I suspect any further uses of it would be a bad idea for the
same reasons, so let's get rid of it.
I'm about to add a list box which expects to contain some very long
but uninformative strings, and which is also quite vertically squashed
so there's not much room for a horizontal scroll bar to appear in it.
So here's an option in the list box specification structure which
causes the constructed GTKTreeView to use the 'ellipsize' option for
all its cell renderers, i.e. too-long strings are truncated with an
ellipsis.
Windows needs no change, because its list boxes already work this way.

Unix GUI programs should not say 'Fatal Error' in the message box
title, and Plink should not destroy its logging context as a side
effect of printing a non-fatal error. Both appear to have been due to
inattentive cut and paste from the pre-existing fatal error functions.

and returns its error message as a string, instead of actually
printing it on standard error and exiting. Now we can preserve the
previous error behaviour when we get a nonexistent font name at
startup time, but no longer rudely terminate in mid-session if the
user configures a bogus font name in Change Settings.

duplicate the strings they pass to gtk_entry_set_text. I was already
doing that in dlg_editbox_set, but forgot to add the same code when I
revamped FontSpec and Filename to contain dynamically allocated
strings (r9314 and r9316 respectively). This fixes a bug where, on
some versions of GTK (but apparently not up-to-date versions), loading
a saved session causes gibberish to appear in file-selector edit boxes
accompanied by a valgrind error.

allocated type.
The main reason for this is to stop it from taking up a fixed large
amount of space in every 'struct value' subunion in conf.c, although
that makes little difference so far because Filename is still doing
the same thing (and is therefore next on my list). However, the
removal of its arbitrary length limit is not to be sneezed at.
[originally from svn r9314]
'Config' in putty.h, which stores all PuTTY's settings and includes an
arbitrary length limit on every single one of those settings which is
stored in string form. In place of it is 'Conf', an opaque data type
everywhere outside the new file conf.c, which stores a list of (key,
value) pairs in which every key contains an integer identifying a
configuration setting, and for some of those integers the key also
contains extra parts (so that, for instance, CONF_environmt is a
string-to-string mapping). Everywhere that a Config was previously
used, a Conf is now; everywhere there was a Config structure copy,
conf_copy() is called; every lookup, adjustment, load and save
operation on a Config has been rewritten; and there's a mechanism for
serialising a Conf into a binary blob and back for use with Duplicate
Session.
User-visible effects of this change _should_ be minimal, though I
don't doubt I've introduced one or two bugs here and there which will
eventually be found. The _intended_ visible effects of this change are
that all arbitrary limits on configuration strings and lists (e.g.
limit on number of port forwardings) should now disappear; that list
boxes in the configuration will now be displayed in a sorted order
rather than the arbitrary order in which they were added to the list
(since the underlying data structure is now a sorted tree234 rather
than an ad-hoc comma-separated string); and one more specific change,
which is that local and dynamic port forwardings on the same port
number are now mutually exclusive in the configuration (putting 'D' in
the key rather than the value was a mistake in the first place).
One other reorganisation as a result of this is that I've moved all
the dialog.c standard handlers (dlg_stdeditbox_handler and friends)
out into config.c, because I can't really justify calling them generic
any more. When they took a pointer to an arbitrary structure type and
the offset of a field within that structure, they were independent of
whether that structure was a Config or something completely different,
but now they really do expect to talk to a Conf, which can _only_ be
used for PuTTY configuration, so I've renamed them all things like
conf_editbox_handler and moved them out of the nominally independent
dialog-box management module into the PuTTY-specific config.c.

during an entire run of unifontsel (because unifontsel_set_name was
either not called at all, or called with a name that didn't

button until a valid font is selected, and we have
unifontsel_get_name return NULL rather than failing an assertion if
it should be called in that state. The current client code in
gtkdlg.c should never encounter a NULL return, since it only calls
it after the OK button is clicked, but I've stuck an assertion in
there too on general principles.

in place of making a network connection. This has involved a couple
of minor infrastructure changes:
- New dlg_label_change() function in the dialog.h interface, which
alters the label on a control. Only used, at present, to switch
the Host Name and Port boxes into Serial Line and Speed, which
means that any platform not implementing serial connections (i.e.
currently all but Windows) does not need to actually do anything
in this function. Yet.
- New small piece of infrastructure: cfg_launchable() determines
whether a Config structure describes a session ready to be
launched. This was previously determined by seeing if it had a
non-empty host name, but it has to check the serial line as well
so there's a centralised function for it. I haven't gone through
all front ends and arranged for this function to be used
everywhere it needs to be; so far I've only checked Windows.
- Similarly, cfg_dest() returns the destination of a connection
(host name or serial line) in a text format suitable for putting
into messages such as `Unable to connect to %s'.

that the global `sesslist' got out of sync with the saved-sessions submenu,
causing the latter to launch the wrong sessions.
Also, Change Settings wasn't getting a fresh session list, so if the set of
sessions had changed since session startup it wouldn't reflect that (at least
until a session was saved). Fixed (on all platforms).
Therefore, since the global sesslist didn't seem to be useful, I've got rid
of it; config.c creates one as needed, as do the frontends. (Not tried
compiling Mac changes.)
Also, we now build the saved-sessions submenu on demand on Windows and Unix.

This was harder than verify_ssh_host_key() and askalg() put
together, because:
(a) askappend() can be called at any time, since it's a side effect
of data-logging functions. Therefore there can be an unfinished
askappend() alert at any time, and hence the OS X front end has
to be prepared to _queue_ other alerts which occur during that
time.
(b) logging.c has to do something with data that comes in while
it's waiting for an answer to askappend(). It buffers it until
it knows what the user wants done with it. This involved
something of a reorganisation of logging.c.
[originally from svn r5344]
now returns an integer: 0 means cancel the SSH connection and 1
means continue with it. Additionally, they can return -1, which
means `front end has set an asynchronous alert box in motion, please
wait to be called back with the result', and each one is passed a
callback function pointer and context for this purpose.
I have not yet done the same to askappend() yet, because it will
take a certain amount of reorganisation of logging.c.
Importantly, this checkin means the host key dialog box now works on
OS X.

ptrs and ints of different size and -Werror makes this serious).
The GTK bits are done by Colin's patch to use GINT_TO_POINTER
(thanks); the uxnet bits are done by cleaning up the rest of the
code. In particular, network.h now typedefs `OSSocket' to be a type
capable of holding whatever the OS's socket data type is that
underlies our socket abstraction. Individual platforms can make this
typedef themselves if they define OSSOCKET_DEFINED to prevent
network.h redoing it; so the Unix OSSocket is now int. Default is
still void *, so other platforms should be unaffected.
