Always enable ASLR and DEP when building GKrellM on Windows. Since
GKrellM also does network communication bugs like buffer overflows and
the like may eventually allow remote code execution. By enabling these
build flags such attacks should be quite a bit more complicated
(although still not impossible).
Add a dependency on the windows build target to allow building and
installing GKrellM using a single target. This fixes calling "make
install_windows" without a prior call to "make windows".
- Export the CC and PKG_CONFIG variables before calling configure scripts,
especially for cross compilation and modified environments, otherwise
configure might detect libraries that are not usable by the compiler
later on
- Replace the hardcoded pkg-config calls in configure with a variable
that may be overridden by Makefile
- Make the server configure script log the environment just like the
configure script used for the client.
- Honour the CFLAGS env var too since the other configure does the same
Do not try to execute generated executables. Altough this is a nice
idea in theory it breaks on cross compile environments which usually
cannot execute binaries of the target platform.
Remove Gtk+2 compile and link flags from all configure tests because:
- no test code depends on Gtk+2
- gkrellmd does not need Gtk+2 at all
- the cflags variable in the src/configure was misspelled and thus did
not have any effect
Override all tools with prefixed versions if the CROSS variable has
been set. This is the recommended way to enable cross compilation using
mxe without touching lots of environment variables first.
Move all make variables and rules duplicated between gkrellm and
gkrellmd makefiles into a common file that can be included. This
avoids duplication and hopefully avoids the two makefiles getting out
of sync too much. This is also a preparation to ease overriding
toolchain binaries (compiler, linker, pkgconfig) as part of windows
cross compiling.
This change also puts the "ar" tool into a variable that can be
overridden if needed.
Please note that this change uses the GNU Make specific include
statement but AFAICS the makefiles already depend on GNU extensions in
other areas (":=" and "ifdef" are non-standard make syntax).
Apply a slightly modified version of a patch provided by Pierre Neyron
that allows to enable/disable new network interfaces by default.
This feature is especially helpful for VM or container setups where many
network interfaces are created.
Adding md5c to the build is already handled by src/Makefile but that
one only kicks in if EXTRAOBJS is not set at all.
This fixes accidental build (and inclusion) of the md5 code that is
normally used from OpenSSL or GnuTLS if one of them is detected.
GLib version 1 is very outdated by now and not available in any recent
Linux distribution. Keeping this code around without actually being
able to test it makes little sense so let's get rid of that.
- Always check the return value of
g_win32_get_package_installation_directory_of_module, this call may
fail and return NULL
- g_build_filename is documented as never returning NULL, no need to
check for that
- Use g_thread_new instead of g_thread create
- Drop explicit call of g_thread_init, it is done implicitely by GLib
since 2.32
- Since this bumps the minimum required GLib version add and extend the
pkg-config based version checks to error out on older GLib versions
The remaining codebase uses g_strdup() already so do the same for the
chime command too. This fixes a gcc warning caused by a missing include
for strdup().
Move all variable and struct init code into if 0 blocks like the code
that is supposed to use this. Eventually this whole cruft can be
dropped altogether in case GKrellM can be ported to use Gtk+ session
management.
- Adding a sensor in the mbmon support stored the added sensor in a
pointer but never used it afterwards
- Drop pixbuf width in draw_left_frame_overlap, the code unlike other
drawing helpers does not use the pixbuf width
- Remove unused scroll selection from net_stats_page
This fixes several set but unread warnings when compiling with a recent
gcc (encountered with gcc 4.8.2).
Read sensor information from the GPU-Z shared memory area if present.
As with all sensor backends on Windows this needs the GPU-Z tool
running in the background.
Do not use a fixed 5 second delay after having a started a windows
sensor application, instead try to access the shared memory area
repeatedly and only give up after 10 seconds. Please note that for this
feature to be usable the sensor app must be found in PATH.
- Move opening and closing of a win32 shared memory area into helper
functions. shm_open ensures that the data pointer is valid and
otherwise gets rid of the opened file handle right away. shm_close
cleans up both the handle and the data pointer if needed.
- Redo the initial check for presence of a sensor tool that uses a
shared memory area for its sensor data by using the above two
functions
- Port all sensor value reading to use shm_open/shm_close as well
This gets rid of some code duplication and also lowers the indentation
level in several areas which hopefully makes the code a bit easier to
read. Additionally all the win32 API calls are limited to two functions.
Do not use the default LINK_FLAGS value for windows builds, the default
"-E" linker option only causes warnings for MinGW since it's essentially
ignored by the linker.
The flag is also unneeded since linking plugins against the gkrellm
binary is not done on win32 so none of the gkrellm/gkrellmd functions
need to be exported, the API is manually exposed via the win32-specific
libgkrellm/libgkrellmd static libs.
Honor the BINEXT variable in the gkrellm and gkrellmd target to enforce
building with the correct extension. This is needed for recent mingw-w64
cross toolchains since those do not automatically append ".exe" when
linking.
On Thinkpads T410s sysfs may switch between energy_full/_now and
charge_full/_now files across suspend/resume. Instead of polling only
one set of files always try all variants when checking battery levels.
This fixes a battery level of 0 in GKrellM after resume.
Thanks to Joern Engel for tracking this down and for providing a patch
via the Debian bugtracker.

Explicitely add needed include arguments as well as linker arguments
for gmodule. Before this change we relied on gmodule being an implicit
dependency pulled in via the gtk+-2.0 module, this does not seem to be
the case anymore with >=gdk-pixbuf-2.24 and >=pango-1.30.
Thanks for Alexandre Rostovtsev for bringing this up on the mailinglist
and for providing a first patch.

Mark mount points of type cifs as remote filesystems to make gkrellm use
nfs-timeout as polling interval instead of the standard fs-timeout which
should only be used to poll local filesystems.
Thanks to Gerard Neil for submitting this patch.
Accessing mount points to determine free space actually triggers a
mounting operation of autofs mounts. This results in all autofs mount
points to be always-mounted while gkrellm is running, something which
is hardly desirable.
Thanks to Gerard Neil for submitting this patch.
Not linking against Libgcrypt is not enough, we also should not try to
include headers. This fixes GnuTLS >= 2.12 detection when Libgcrypt
headers are not installed/found.
Only initialize Libgcrypt threading functions on GnuTLS < 2.12 which
does not do this automatically. Also drop explicit linking against
Libgcrypt on newer GnuTLS version.
This should allow GKrellM to work with a GnuTLS that uses Nettle instead
of Libgcrypt as its cryptographic backend.
