- Does away with the O_BINARY abomination
- as a byproduct, plugs an fd leak in wcolorpanel.c:fetchFile()
- sprinkle some fsync()s to files that have been written to (this
needs to be done everywhere)
+ fix brown paper bag thinko in configure.ac
As the README used to say, it was a unfinished work. If someone
wants to finish it after all these years it can be recovered
from the logs. But meanwhile let's not carry dead code around.
- add new wglobaldefaultspathfordomain() to wings (replaces several
hand-rolled individual implementations in utils/)
- make all of 'em handle -h|--help, -v|--version
- try making them not to nothing silently
- change various ways of knowing thyselves to using __progname
- generally try to make them feel similar (NOT right, similar --
right is a completely different matter)
- make it use wings functions, remove duplicated code from getstyle
- de-static necessary functions in wings
- add new wrmdirhier to wings
- rename WMMkDirHier to wmkdirhier (fits better)
- remove calling shell from getstyle (what were they thinking?)
i couldn't quite test getstyle (no idea about themes), but it still
basically works.
do back your ~/G dir up... wrmdirhier might eat it!
definitely needs testing, especially by people who have any idea
how themes work.
Some more getstyle
- missed a shell invocation
- maybe copyFile should be in wutils too...?
[crmafra: Folded second patch into the first]
make wtrimspace() use wings' own function for a task
semantics change: it used to segfault given null, now it returns null.
this doesn't affect any current use (there's exactly one..), and i see
no harm in this behaviour, and perceive this to be more natural.
The result is not much more convoluted than the original was, but much shorter.
Several vararg macros were added -- no idea what !gcc compilers make of this.
The messages sent to these functions are inconsistent across the source tree.
I have now decided that the logging function will add the final newline -
messages will need to be modified accordingly.
I have no idea why the original implementation was as complicated and ugly as
it was. My guess is that it was anticipated that these are be called from
sighandlers, but why no snprintf when they are all stuffed up with vsnprintf...
Still, the result is not worse in this regard either.
It addresses this warning
dialog.c: In function ‘LoadHistory’:
dialog.c:209: warning: passing argument 2 of ‘WMFindInArray’ from incompatible pointer type
../WINGs/WINGs/WUtil.h:455: note: expected ‘int (*)(void *, void *)’ but argument is of type ‘int (*)(const void *, const void *)’
but induces others in other places. One of them was this one
window.c: In function ‘wManageWindow’:
window.c:782: warning: passing argument 2 of ‘WMFindInArray’ from incompatible pointer type
../WINGs/WINGs/WUtil.h:455: note: expected ‘int (*)(const void *, const void *)’ but argument is of type ‘int (*)(void *, void *)’
which is fixed by constifying the arguments of matchIdentifier(). The other warnings are
fixed similarly.
remove the choice of atomic/non-atomic writes. firstly, the only users
of non-atomic writes were getstyle and geticonset; secondly, who in their
right minds would ever want non-atomic writes; thirdly, the file system
will screw you anyway *G*.
...which creates directory hierarchies under $GNUSTEP_USER_ROOT
- make WMWritePropListToFile() use this
readily solves the "run dialog history vs nonexistent state dir" case.
if other consumers are found for this, just de-static and move the
prototype to WUtil.h or some other appropriate place.
This patch modifies the linking of the WINGs libraries
to create a shared library. wmaker used to do this, but
it was dropped around wmaker-0.90/0.91.
The shared .so library is needed when compiling and running
the wdm display manager and any other programs which link
to libWINGs.

The man page of XChangeProperty() says:
"If the specified format is 32, the property data must be a
long array."
And as we call it with format 32, the type of 'data' must
be 'long'. It happens to work nowadays in 32-bit architectures
because sizeof(CARD32) = sizeof(long), but that is no longer
true in 64-bit mode.
This patch was downloaded from
www.openbsd.org/cgi-bin/cvsweb/ports/x11/windowmaker/patches/patch-WINGs_wwindow_c
and I thank Alexey I. Frolov and Vladimir Nadvornik for helping me
to understand it on a wmaker-dev thread.
This patch adds history to some dialog boxes. To use it replace %a with
%A in menu file (like in "Run..." menu item). You can specify third
parameter to %A to use different histories for differen dialogs.
All history files is kept in ~/GNUstep/.AppInfo/WindowMaker/ and the number of
history lines controlled by DialogHistoryLines parameter (one for
all dialogs) defaults to 500 lines.
It also adds Tab completion.

These are some of the fixes sent to the wmaker-dev list by
Vladimir Nadvornik, with minor modifications to address Dan
Pascu's concerns.
Original-post: http://lists.windowmaker.info/dev/msg00293.html
wtokenfree() does not free the first entry of an array.
If count is 1 then
while (--count)
will be
while (0)
and the inner body of that while-loop will not be entered.
Therefore a memory leak happens every time wtokenfree() is called.

[crmafra: This patch, altough correct, breaks WPrefs.app, which will be
fixed by the next patch. ]
Problems:
1.
During expansion of path, the resulting path can overflow the supplied
area of PATH_MAX+2 (buffer as well as buffer2). A tampered environment
variable can be used to modify program flow.
Proof:
[note: wmaker has been compiled with propolice]
$ export A="[tested with 4096x A]"
$ GNUSTEP_USER_ROOT="\$A\$A/\$A/\$A/" wmaker --for-real
*** stack smashing detected ***: wmaker terminated
Aborted
2.
Way too many functions handle a return value of NULL for wexpandpath
improperly, resulting in segfaults (and maybe other problems). To
prove the existance of these issues:
Proof:
$ GNUSTEP_USER_ROOT=~nouser wmaker --for-real
wmaker error: could not get password entry for user nouser: Success
Segmentation fault
Solution:
hard exit with error message about what is going on.
3.
The improper parsing of environment variables can lead to expansion
of path names that were not intended to be expanded.
(a) If a string like "$(var" is found, Window Maker tries to expand "var"
(environment variable) although the syntax is wrong.
Proof:
$ export PROOF=foo
$ GNUSTEP_USER_ROOT=/\$\(PROOF wmaker --for-real
wmaker warning: could not find user GNUstep directory (/foo/Defaults/WindowMaker).
(b) If the variable out of a) cannot be resolved, a closing bracket will be
added.
Proof:
$ unset PROOF
$ GNUSTEP_USER_ROOT=/\$\(PROOF wmaker --for-real
./wmaker warning: could not find user GNUstep directory ($(PROOF)/Defaults/WindowMaker).

This patch addresses this warning of gcc:
wfontpanel.c: In function 'listFamilies':
wfontpanel.c:588: warning: missing sentinel in function call
Fix it by using the 'NULL' pointer instead of 0 (zero) as the
sentinel.
For more information, see
http://www.linuxonly.nl/docs/2/2_GCC_4_warnings_about_sentinels.html
in particular,
"On most systems, there is no difference between 0 and (char *)0.
On 64 bit systems, however, the integer 0 is 32 bits and the
pointer 0 is 64 bits. The compiler does not know whether it is
an integer or a pointer, and defaults for the integer. This will
not clear the upper 32 bits and the function will not stop
scanning its parameters."
Note that here in my 64-bit Mandriva I don't need to cast (char *)NULL.
There may be issues with running applications in 64-bit mode when
they were written with tacit assumptions about 32-bit platforms.
For example,
* Assuming that a pointer can be cast back and forth to an integer
The reason is that the size of the integer and pointer may be different.
See the description of "[PATCH] Warn when casting a pointer (constant)
to an integer of different size." in the gcc mailing list
http://gcc.gnu.org/ml/gcc-patches/2005-12/msg01881.html
where it was also suggested the use of casts to uintptr_t. This is
what this patch does.

This patch adds the --disable-verbose-compile switch to the
configure script.
When this option is used it reduces the verbosity of compilation
messages to the essential. However compiler warnings are not affected
and thus gain visibility by not standing in the middle of a storm
of other messages.
In summary, the compilation messages are reduced to a stream of
CC array.o
CC bagtree.o
CC configuration.o
CC connection.o
CC data.o

WPrefs tries to use the fonts listed in the WMCreateFont() call (from WPrefs.c),
font = WMCreateFont(scr, "Lucida Sans,URW Gothic L,Times New Roman,serif"
":bold:pixelsize=26:antialias=true");
and 'font' is later used without accounting the possibility of it being NULL in
WMSetLabelFont(WPrefs.nameL, font);
WMReleaseFont(font);
In particular, WMReleaseFont(font) will kill WPrefs ungracefully with the
following message if font=NULL
WPrefs: wfont.c:193: WMReleaseFont: Assertion `font!=((void *)0)' failed.
Aborted
That happens because the return value of WMCreateFont() can be NULL, so this
patch makes WMCreateFont() never return NULL. If the font creation fails for
some reason (see below), we try to use the emergency DEFAULT_FONT and print
debugging information telling what's going on. If the use of DEFAULT_FONT
also fails, then we terminate WPrefs with exit(1) and let the user know
why exactly if failed.
This bug happened because the font "Lucida Sans" (the first possibility
in the initial call to WMCreateFont()) "exists" in my system as a stale
symbolic link to a location which no longer exists after an upgrade from
java from 1.5.0.14 to 1.5.0.15
/etc/alternatives/LucidaSansDemiBold.ttf ->
/usr/lib/jvm/java-1.5.0-sun-1.5.0.14/jre/lib/fonts/LucidaSansDemiBold.ttf
So the call to XftFontOpenName(display, scrPtr->screen, fname) with
"Lucida Sans" being the first possibility for Xft to try out ended up in 'font'
being NULL because, as far as the Xft library was concerned, "Lucida Sans"
produced a positive match (due to it existing as a symbolic link) but in the end
a NULL result was produced due to the missing symbolic link destination. This later
exposed the bug of WMCreateFont() returning font=NULL and WPrefs.c not checking
whether font=NULL before using it. Bang!
If "Lucida Sans" was the _second_ entry to try and the first one had suceeded,
this bug would not have surfaced.

This patch removes wmaker from PowerTop's shame list, where
it appeared with ~3-4 wakeups/second.
It adds the linux kernel's dnotify mechanism (adapted from
the example in Documentation/dnotify.txt in the kernel source),
to detect when a configuration file in ~/GNUStep/Defaults has
changed to load it again on-the-fly. For me it usually means that
modifications to ~/GNUStep/Defaults/WMRootMenu via the 'genmenu'
script are automatically detected and loaded.
The use of dnotify makes the ancient behaviour of polling unecessary
and cuts down the wakeups count.
Other 'apparently' useless timers are also deleted and it's been almost
one year now that I use this patched exclusively without problems, so
I am pretty sure that it doesn't hurt to remove them.
The end result of all this is that wmaker generates 0 (zero) wakeups
when idle in a Linux system.

This also fixed an endless loop that could be entered by the previous code
in certain situations, after the patch to fix navigation/selection in a
textfiled with UTF8 chars was applied.
fix the 2 problems mentioend below:
- Fixed buggy handling of UTF8 characters in textfields in WINGs.
- Fixed segfault in WPrefs when some font description is missing from the
configuration file.
WINGs based applications should now work with both KDE and GNOME
applications (Sylvain Reynal <sreynal@nerim.net>)
- better check for the XDND protocol version when interoperating with other
applications. As it seems xdnd version 3 (which WINGs supports) and newer
are not backward compatible with xdnd version 1 and 2. This is why WINGs
applications cannot interoperate with GNUstep applications (which uses
xdnd version 2). Xdnd version 4 and 5 are backwards compatible with
version 3 though. (Sylvain Reynal <sreynal@nerim.net>)
