Re: [Plplot-devel] Java tests on Mac OS X fail
Hi Andrew, Werner, From what you have said this looks like a problem with the plcont routine. This uses a common block to share the transform data between plplot and the user code. From what is being plotted I think this is not being properly shared. There is some comment magic to import / export this for some compilers. Can you confirm which fortran compiler you are using? Do you have any idea if there are any special pragmas required for exporting common blocks on this compiler? The compiler is gfortran (it's used for f77 and f95) GNU Fortran (GCC) 4.2.3 Copyright (C) 2007 Free Software Foundation, Inc. GNU Fortran comes with NO WARRANTY, to the extent permitted by law.

For more information about these matters, see the file named COPYING I can't remember where I downloaded it from and I'm not sure, which gfortran compiler I should get for Mac OS X to update the compiler. Regards, Werner This is all a bit of a kludge to fix up for not using function pointers in fortran. In fact we've now worked out how to do this properly (see e.g example 19 with mapform). How do people feel about fixing the pltr functions properly for fortran? This probably requires working out what to do with PLPointer data. It would be nice if we could get all languages working the same. Andrew -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

[Plplot-devel] [PATCH] Compiler warning fixes
Hi,
The attached patches fix some compiler warnings:
plargs-patch Make sure the functions return a value.
cairo-patch Properly place parentheses, avoiding code having no effect.
I also noticed with gcc -Wall there are a lot of unused variables in
plplot, if wanted I could provide a patch which removes those variables.

There is obviously a conflict, but nothing that would stop the software to work, so it is a choice for the developer to filter out or not the -bg arguments or make them available to either QApplication or the widget. Maybe we should add a comment there? I have fixed this issue in revision 10347. I set argc (but not Argc) to 1 so that QApplication sees only an empty command line (other than the command, itself). I prefer the simplicity of this approach for our qt_example, and I assume most Qt/PLplot GUI application developers will stick with that model where the command-line options are completely ignored by Qt and only interpreted by PLplot. However, I put additional commentary in so that if application developers want to allow both Qt options and PLplot options (say by splitting the two kinds of options by a special -- option like startx does for its two kinds of options), and putting one kind into argc for QApplication and the other kind into Argc for PLplot, it should be straightforward for them to do so.

I am somewhat concerned about adding another function to the core API because of the costs of propagating that function to other languages, documenting it, and extending a standard example (in all our languages) to use it. Could this be implemented as a driver option instead that is set either on the command-line or with plsetopt?

[Plplot-devel] Segmentation fault with qt driver
While testing the qtwidget and other PLplot qt output devices I ran in to two issues. This is on Ubuntu 9.04 64bit, with the system Qt version (4.5.0). The first issue is similar in feel to an long-lived, ongoing Cairo problem - calling plinit and selecting a qt device after a call to plend causes a segmentation fault. Simply calling plinit(); plend(); plinit(); (selecting a qt device each time) is enough to trigger the bug here. I don't know if this happens for every qt device, but it happens consistently for me with the qtwidget device. Similar to the Cairo bug, calling plend1 rather than plend avoids this bug. Unlike the Cairo bug, no text rendering is required to trigger the qt segmentation fault. The second issue relates to using plend1. For example: plsdev qtwidget; plinit (); plenv 0. 1. 0. 1. 1 0; plend1 (); plsdev qtwidget; plinit (); plenv 0. 1. 0. 1. 1 0; plend1 (); The first call to plend1 will not display a plot, just the plot window with (on my system) a grey hatched background. The second plend1 call will show the plot. I don't use the qt driver except for occasional testing, so I'm not sure if these are PLplot bugs or bugs in some other library (for example, Qt 4.5.0 vs a later release). Hez -- Hezekiah M.

This is on Ubuntu 9.04 64bit, with the system Qt version (4.5.0). The first issue is similar in feel to an long-lived, ongoing Cairo problem - calling plinit and selecting a qt device after a call to plend causes a segmentation fault. Simply calling plinit(); plend(); plinit(); (selecting a qt device each time) is enough to trigger the bug here. I don't know if this happens for every qt device, but it happens consistently for me with the qtwidget device. Similar to the Cairo bug, calling plend1 rather than plend avoids this bug.

When persistent memory management problems (segfaults, etc.) are identified like this, I think it is important to add a simple C test routine to demonstrate the problem so we have an exact test case to talk about since _the symptoms_ of fundamental memory management issues can come and go depending very much on minor programming detail variations as well as platform, phase of the moon, etc. IOW, relying on segfaults to tell us about memory management issues is a first step, but valgrind is the only way (at least on Linux) to get definitive results. I have made such a test case in revision 10348 (which demonstrates exactly how to add such a test for our build system). It will build automatically in the build tree for BUILD_TEST=ON and also automatically in the installed examples tree. For this particular test (plend1, then plend), all is well even for valgrind tests of -dev qtwidget and -dev xcairo, but if that first plend1 is replaced by plend there are huge memory management problems revealed by valgrind for both -dev xcairo and -dev qtwidget (but not -dev xwin or -dev psc). This is for Qt version 4.5.1 downloaded from trolltech. I have forgotten the exact differences between plend and plend1, but I know the former calls the latter than does a bit more to completely close the plplot library. I guess that bit more is causing the problems (or else the subsequent plinit after a complete close of plplot is exposing reinitialization bugs for both the cairo and qt devices.) Andrew, I intend to look at this (especially the differences between plend and plend1) a bit more, but you are our expert on memory management issues so I hope you take a look as well.

It turned out there was a bug in our build system for the case where the Qt4 development environment was not found. I have now fixed that (revision 10349). Could you please try the exact same build again to make sure everything works now for the no Qt4 case? Once you confirm that works, you will probably want to build your Fedora rpms in an environment where Qt4.5.x has been installed so Fedora users get access to all the qt device goodies.

Re: [Plplot-devel] Segmentation fault with qt driver
Hi Hez: This is mostly for you but there are some reassuring remarks for Alban here as well. On 2009-08-26 15:13-0700 Alan W. Irwin wrote: When persistent memory management problems (segfaults, etc.) are identified like this, I think it is important to add a simple C test routine to demonstrate the problem so we have an exact test case to talk about since _the symptoms_ of fundamental memory management issues can come and go depending very much on minor programming detail variations as well as platform, phase of the moon, etc. IOW, relying on segfaults to tell us about memory management issues is a first step, but valgrind is the only way (at least on Linux) to get definitive results.

This is for Qt version 4.5.1 downloaded from trolltech. I have changed plend1 to plend in the test example as of revision 10350. So it now reads in its heart as follows: plinit(); plenv(0., 1., 0., 1., 1, 0); plend(); plinit(); plenv(0., 10., 0., 10., 1, 0); plend(); exit(0); After a cmake configuration with BUILD_TEST=ON, and make, examples/c/test_plend -dev xcairo now produces a segfault as I said above. However, that same application is valgrind clean for -dev qtwidget (and other qt devices I have tested such as svgqt and epsqt)! I scrolled up my xterm to where I did my qt tests before, and I definitely got a segfault before with -dev qtwidget, but this was an original test case which was built by hand, and the cmake build system build seems to have eliminated all memory management problems with qt (but not cairo). So this is an excellent illustration of my point above to use easily reproducible results when dealing with memory management issues. :-) Anyhow, Alban, we are back down to zero known errors for qt (with Qt4.5) on Linux. I suggest everybody (especially Hez who got -dev qtwidget segfaults with his own hand-built plend/qt tests like I did) try examples/c/test_plend for various qt devices for their Qt4 version and OS platform to make sure all is well with that test example for qt in a platform-independent way. I wonder how many minutes the zero known errors remark will last this time for qt. :-) I have forgotten the exact differences between plend and plend1, but I know the former calls the latter than does a bit more to completely close the plplot library. I guess that bit more is causing the problems (or else the subsequent plinit after a complete close of plplot is exposing reinitialization bugs for both the cairo and qt devices.) Hez, I suggest you look at plend for yourself to see the really innocuous things that are going on. It calls plend1 for all streams, then releases all memory associated with Hershey fonts, dynamic drivers, and static drivers. That's basically it. In fact, if you modify test_plend.c to comment out the second plinit, plenv, and plend then the result is valgrind clean for -dev xcairo. So the problem cannot have anything to do specifically with the combined memory management of xcairo and plend alone. plend does set lib_initialized = 0 which means pllib_init (called by plinit) actually does something (restores the memory freed by plend and sets lib_initialized = 1), but again this is pretty innocuous stuff. So I doubt very much the problem lies specifically with pllib_init, and that view is supported by every other device driver having no troubles with revision 10350 of test_plend.c. Thus, I would look carefully at what happens with the cairo devices when you initialize them for a second time after memory associated with dynamic drivers has been freed and reinitialized. Wild guess: do the cairo devices hang on to some memory when they shouldn't so at reinitialization time they are still pointing at the old dynamic driver (dispatch table) memory that no longer exists because it has been freed (and allocated again) in the plend case? That freeing and allocation is the most prominent difference between plend followed by plinit versus plend1 followed by plinit. Hez, I hope this overview of plend, plinit, and pllib_init and the knowledge that no other device driver has problems (at least for the test_plend case), helps you to quickly find the issue in the cairo case.

[Plplot-devel] Problematic floating-point comparisions
Valery Pipin reported the following warning to me: *** PLPLOT WARNING *** Unrecognized cmap1 format #ff 100 0 At first glance that is impossible. The line in question is the last line in cmap1_default.pal, and that is just as perfectly formatted as the other lines in that file. However, a closer look at the code in plctrl.c showed a problematic floating-point test for whether pos[i] (calculated from the above 100 value by converting to double and multiplying by 0.01) was in the range from 0. to 1. I have now fixed that test as of revision 10351 to account for small floating-point errors in the calculation of pos[i]. Valery hasn't yet gotten back to me, but when he does I presume he will tell me that fix worked. This whole issue shows how important it is to run PLplot on a large variety of hardware with different floating point errors so that we find problematic floating-point comparisons like what I just spotted and fixed in plctrl.c. Anyhow, if you have access to PowerPC's, sparcstations, Dec Alphas, IBM mainframes or other non-Intel hardware, now would be a good time to do some thorough checking of PLplot on that hardware.
