As pointed by Coverity, the function 'WMGetTextFieldText' already allocates
memory for its return string, so it is not necessary to wstrdup it.

As pointed by Coverity, there is a possible NULL pointer dereference in the
code that extracts the selected modifier (from a popup button list).
The code assumes that there is always a space between the core name of the
modifier (which is used for saving) and the more user friendly name. This
is true if the list could be successfully generated in fillModifierPopUp,
but it may not be the case if that function has to fall-back to the
default list (XGetModifierMaping failure).

As pointed by Coverity, it is possible to dereference the NULL pointer in
the function 'browseForFile'.
This should have been reported by the compiler ("possible use of
uninitialised variable") but the assignation of a default value to the
variable 'lPtr' hides this, but as the default value is not a good one then
the code could crash.
This patch removes the default value, so we may have some info from the
compiler and handles the case smoothly.
It also fixes a potential memory leak pointed also by Coverity in the
case where the string returned by WMGetFilePanelFileName would be a 0
length non-null string.

As pointed by Coverity, the return value of 'sscanf' is not checked, which
may not be a problem because the fall-back value for 'i' is provided before.
However, if sscanf fails there is no guarantee that all implementation would
leave 'i' untouched in case of parsing error, and for convenience it is more
logical to write the code is such a way that the value assignment looks like
the fall-back value it is.

cppcheck is reporting the msg below:
[../WINGs/winputmethod.c:215] -> [../WINGs/winputmethod.c:209]:
(style) Found duplicate branches for 'if' and 'else'.
The patch is fixing it by setting a default return call.
With a set of images i was able to detect that
the flip functions was shifting the image by 1px.
The 90 and 270 degrees rotation were not working as
the functions were also mirroring the img.
The patch is also fixing the C style based on checkpatch.
when the rotation angle value passed to RRotateImage is a modulo of 90,
the function is working well but in other cases the rotateImage()
function is called. That last function is half implemented but
the half already implemented part is also segfaulting (use the testrot.c
to replay the crash).
So the patch is moving the 'not implemented' msg to disable the whole
rotateImage() function and comment it out.
As pointed by Coverity, the function GetCommandForPid did use a macro
'RETRY' for the 'close' of file descriptor, which is not correct because
on success the function 'close' does not reset errno, and in case of
failure the file descriptor is not more valid anyway.

Factually, the program works because the function 'drawerRemoveFromChain'

As pointer by Coverity, the function wstrappend may move the string in

The function wIconChooserDialog already makes sure that it returns

According to NEWS, the DisplayFont option was removed in version 0.62.0 and
replaced by the WINGs system font. However, it was still referenced in a large
number of style files, as well as the utils getstyle, setstyle, convertfonts,
and the manpages for getstyle and setstyle. This patch removes all of these
references.
In addition, it updates the Czech, Slovak, and Russian translations of these
manpages to match the English versions. Note that I relied on Google translate, and it appears I may have re-encoded some characters when I saved the Czech
and Slovak files -- if you speak these languages, please take a look!
A few minor spelling errors were corrected in the English manpages.
The coding style in wmaker.git follows the conventions of the linux kernel.
Therefore, I'm stealing their 'checkpatch' tool in an attempt to maximize
"perfect" patches to wmaker-dev, at least coding-style wise :-)
Before submitting your patch, please ('please' here means you must) check
it with:
./checkpatch your-patch.diff
and use your common sense to address any violations (error and/or warnings) detected.
There will always be false positives and other complaints that sometimes are better
dealt with by leaving them alone. No tool is perfect, but it _will_ detect obvious
errors which you must fix (warnings can be sometimes ignored).
I modified the script by removing kernel-specific stuff, but I don't guarantee
that I removed everything. I also increased the line length warning to 115.
In any case, it seems to work here and hopefully it will lead to a cleaner
and more consistent code base for wmaker.
PS: You can also check existing files, e.g.,
./checkpatch.pl --file src/icon.c
The color well contains two views: view, consisting of the outer "button", and
colorView, consisting of the color itself. Previously, only clicking on view
would bring up the corresponding color panel, resulting in nonintuitive
behavior.
In response to Amadeusz's comments regarding my patch "WPrefs: Add ability to
edit FrameBorderColor/FrameSelectedBorderColor", this new patch attempts to
reduce the confusion between focused and selected windows. In particular,
only the frame border color for non-selected windows appears in the preview.
The frame border color for selected window colors can still be changed, but it
does not appear in the preview. In addition, the hand icon has been removed
from the preview for these two options.
I also looked into the possibility of adding a new border color for focused
windows. This appears to be nontrivial, as the border color belongs to
WFrameWindow, but the state of being focused belongs to WWindow.
When the condition can be simply checked in an if, it is better to do that
than to use a flow breaking goto.
