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.)?

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

Bored!

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. Here we discuss how to extend Pike, not how to use it. Isn't there still a Pike user-list at pike(a)roxen.com?

get_url_data
by Peter Bortas ＠ Pike developers forum 28 Sep '02

28 Sep '02

Protocols.HTTP.get_url_data and Protocols.HTTP.get_url_nice are in my opinion flawed. According to the docs "0 is returned upon failure". That failure will have to be pretty severe though. It will return data as long as the server responds properly. Error codes are ignored. They would gain usefullness if at least the 4xx and 5xx series of errors are considered "failures". Unless the 1xx and 3xx-series are handle somewhere they should also return 0. I'll fix the code if noone protests.

Gz testsuite memory usage
by Henrik Grubbstr�m (Lysator) ＠ Pike (-) developers forum 27 Sep '02

27 Sep '02

Since many of the structures are allocated via block_alloc.h, it would probably be a good idea to let block_alloc.h:really_free_DATA() be able to free entire blocks too.
