Pike autodocs scripts, a helping hand, please?
by Marek Habersack (Grendel) ＠ Pike (-) developers forum 05 Oct '02

05 Oct '02

Just one, little question :) - is there any documentation about the meaning of the tags/attributes in refdoc/structure/modref.xml? I'm trying to make autodocs work on Caudium tree and I'm having problems with one subtree where the documentation extracted from this sample tree: Cache.pmod/Client.pike Storage.pmod/Client.pike Is merged in a flat fashion (the sub_module.xml files from those dirs are merged as if they were in one directory) which generates a 'Duplicate class' error. I imagine it has something to do with the structure defined in modref.xml (or, rather, it's Caudium equivalent) - I'd really, really appreciaty any hints and help on that one. :) TIA

I started looking at why the Gz module won't load on W*ndows with dynamic modules, while most others (such as Regexp) do. DLDEBUG had the following to say: First the Regexp module (which works): dlopen(z:/home/peter/hack/Pike/7.3/build/microsoft-windows-xp-5.1.2600-x86/lib/modules/___Regexp.so,0) filesize(z:/home/peter/hack/Pike/7.3/build/microsoft-windows-xp-5.1.2600-x86/lib/modules/___Regexp.so) filesize(z:/home/peter/hack/Pike/7.3/build/microsoft-windows-xp-5.1.2600-x86/lib/modules/___Regexp.so) Opening file: z:/home/peter/hack/Pike/7.3/build/microsoft-windows-xp-5.1.2600-x86/lib/modules/___Regexp.so Reading ... tmp=0 len=17764 x=17764 errno=2 Done reading dl_load_file dl_loadcoff dl_load_coff_files(01325BE0,00EDBDBC,1) DL: counting DL: 16dcb28 20 0 40 DL: section[0,0], 1536 bytes, align=16 (0x60500020) DL: section[0,1], 518 bytes, align=4 (0xc0300040) DL: section[0,2], 6080 bytes, align=16 (0x60500020) DL: section[0,3], 804 bytes, align=4 (0xc0300040) DL: section[0,4], 36 bytes, align=4 (0xc0300080) DLINFO(113): -defaultlib:uuid.lib -defaultlib:LIBCMT -defaultlib:OLDNAMES -export:_pike_module_exit -export:_pike_module_init Parse link info ptr=0 Parse link info ptr=0 len=20 '-default' Parse link info ptr=21 Parse link info ptr=21 len=18 '-default' Parse link info ptr=40 Parse link info ptr=40 len=20 '-default' Parse link info ptr=61 Parse link info ptr=61 len=25 '-export:' Parse link info ptr=87 Parse link info ptr=87 len=25 '-export:' Parse link info done.

First, there is no "-export:_pike_module_exit -export:_pike_module_init" in the DLINFO. Second, and even more alarming: Not a single symbol is found in the file. Ok, now running strings on the Gz.so to see if the symbols are actually missing or of it's only dlopen.c which fails to read them: [marcus@danae modules]$ strings -a Gz/module.so |less .drectve /DEFAULTLIB:"uuid.lib" -defaultlib:uuid.lib -defaultlib:LIBCMT -defaultlib:OLDNAMES [marcus@danae modules]$ Hm. That's it?? Suspicion starts to dawn. [marcus@danae modules]$ ls -l Gz/module.so -rw-rw-r-- 1 peter peter 144 Sep 24 16:33 Gz/module.so [marcus@danae modules]$ Right. I think it's safe to say that not only are the symbols missing, the actual code is too. Runnings strings on Gz/zlibmod.o shows that the symbols are there at least, so it's the linking that has failed. The buildlog only says Making Gz make[5]: Entering directory `/mnt/aphraelraid/home/peter/hack/xenofarm/client/pike/vmwarexp.bortas.org/buildtmp/Pike7.3-20020924-135500/build/microsoft-windows-xp-5.1.2600-x86/modules/Gz' Compiling /mnt/aphraelraid/home/peter/hack/xenofarm/client/pike/vmwarexp.bortas.org/buildtmp/Pike7.3-20020924-135500/src/modules/Gz/zlibmod.c Linking Gz Pike Win32 partial linker. $Id: pntld,v 1.14 2002/09/12 17:11:40 peter Exp $ Written by Fredrik Hubinette 2000 - 2001 Creating module.so make[5]: Leaving directory `/mnt/aphraelraid/home/peter/hack/xenofarm/client/pike/vmwarexp.bortas.org/buildtmp/Pike7.3-20020924-135500/build/microsoft-windows-xp-5.1.2600-x86/modules/Gz' so no clues there. The only difference I can see in the Makefiles for Regexp and Gz is that Gz has MODULE_LDFLAGS= -R/lib -L/lib -R/usr/local/lib -L/usr/local/lib -R/usr/X11R6/lib -L/usr/X11R6/lib -lshell32 -lkernel32 -lws2_32 -ladvapi32 -lm while Regexp just has MODULE_LDFLAGS= -R/lib -L/lib -R/usr/local/lib -L/usr/local/lib -R/usr/X11R6/lib -L/usr/X11R6/lib but I don't think that's the problem, since Gmp has virtually the same MODULE_LDFLAGS as Gz (including all the -lshell32 etc) and that module works. What's going on here? Hubbe?

Autoconf macros and aclocal
by Niels M�ller () ＠ Pike (-) developers forum 01 Oct '02

01 Oct '02

In theory, I think the best way is to do as follows: When hacking XML2-support (or whatever support) for pike, copy the XML2-recommended m4 macros into aclocal.m4 or some other file included into configure.in in one way or another. Check all that into the Pike cvs. configure.in should be system independent, and should use the same macros no matter if XML2 happens to be installed at buildtime or not. Is there any reason that can't work? / Niels Möller () Previous text: >2002-08-29 22:42: >Subject: Autoconf macros and aclocal >-------------------------------------------------------------------- >Guys, what's the policy about using the aclocal .m4 macro files provided >with some libraries (like GTK+, XML2 etc.)? Should I include the macro in >the src/aclocal.m4 or just put the AM_* macro right in the configure.in and >rely on the .m4 file presence on the system where Pike is compiled/exported? > > / Marek Habersack (Grendel) >

Gz testsuite memory usage
by Marcus Comstedt (ACROSS) (Hail Ilpalazzo!) ＠ Pike (-) developers forum 30 Sep '02

30 Sep '02

I did some simple memory profiling of the testsuite wrt the Gz module. Before testing Gz: [...] 001CC000 64576K read/write/exec [ heap ] [...] total 116856K After tests with constant strings, before tests with random strings: [...] 001CC000 64576K read/write/exec [ heap ] [...] total 116856K After all Gz tests: [...] 001CC000 95936K read/write/exec [ heap ] [...] total 148216K The last randomness test uses about 32 megs, so it's natural for the heap to grow to 96M if all the 64M that made up the previous heap is actually used. Question is, why would there be 64M used heap space at the entry to the tests? A freshly started pike has only 2.5M of heap, so the previous tests must have left 61M of now unused data still referenced somehow. (Some of it can be attributed to internal fragmentation of course, but considering the size of the block we shouldn't have _that_ much fragmentation.) I'm going to try it again with some gc()'s sprinkled through the tests.

so about image processing. sure I know that tgere is gxml but I dont have any samples or documentation how to edit some image and show it to user in web browser there is some stuff I done by my self. this is maximum I can figure out in attachments you can see what I have done and there it is on web http://katalogs.core.lv/demo peace of script. this section will build thumbnails from images in selected folder (on the web page you can see) buff = Stdio.read_bytes("/box1/demo/"+id->variables->cat+"/"+id->variables->img); if (buff != 0 ) { object OurImage; OurImage = Image.JPEG.decode(buff); float xsize = (float) OurImage->xsize(); float ysize = (float) OurImage->ysize(); float scale = 1.0; if (xsize > ysize) scale = ((float) 90)/xsize; else scale = ((float) 70)/ysize; OurImage = OurImage->scale(scale); reply = Image.JPEG.encode(OurImage); array dir = get_dir("/box1/boss/demothumbs/"+id->variables->cat+"/"); if (arrayp(dir)==0) { mkdir("/box1/boss/demothumbs/"+id->variables->cat+"/"); } open_res = me->open("/box1/boss/demothumbs/"+id->variables->cat+"/" + id->variables->img,"cw"); if (open_res == 1) me->write(reply); me->close(); } else { open_res = me->open("/box2/fotodata/default/not_found.gif","r"); reply = me->read(); me->close(); } so there I made decode and encode jpg image and image resizing so I wan to add there more image pike options like sharpen blur colorize lighten darken and more (or also draw some ither image transparent gif as logo ) of course these options will be seperated by if conditions it would give ability to proccess images on the fly and add some effects on the web site you can see some samples I have done with cimg and gtext but I dont like this pike is faster and more options more actualy I wan to create a web site where users can pick some image put some nice text on it some masks effects borders . in one word . add on image some stilistic stuff and in result will get very nice personalised postcard .. also it is important for web site creation dinamicaly draw texts effects and more on images

I'm trying to keep up this this conference, but the signal-to-noise ratio is getting really low. Now I'm going to kill-file this particular thread and hope that (i) it really doesn't lead anywhere, and (ii) that it's an exception in this forum. (I'm commenting a random text in the thread, I'm not saying that the particular commented text is noise). / Niels Möller () Previous text: >2002-09-03 18:03: >Subject: argv[0]? >-------------------------------------------------------------------- >That's not really an all that common usage. >You usually have some code in between fork() and exec(). > >Otherwise you generally speaking use the system functions to start >programs, such as popen(). > > / Per Hedbor () >

Scarpening: ... OurImage = Image.JPEG.decode(buff); OurImage = OurImage-> apply_matrix( ({({-1,-1,-1}), ({-1, 12,-1}), ({-1,-1,-1})}) ); ... This is not the right forum for these kind of questions.
