Yes, we run DNS through NIS (we think :-) An excerpt from the file /var/yp/Makefile (SunOS 4.1.1 b with numereous patches): # Set the following variable to "-b" to have NIS servers use the domain name # resolver for hosts not in the current domain. B=-b Reading the documentation of sun, I think this should do the trick. Possible "problems" at our site: 1) The NIS server is behind a firewall machine. However, he can reach a machine running named, which is specified in /etc/resolv.conf 2) We have an /etc/hosts file, which gives base set of hosts. I am not sure this are the exact problems -- but I know there are more sites which need the resolv library!

I've got a problem with my ancient X r3 server running chimera on a mono display. It seems that r3 doesn't properly free color cells on a mono display. I don't know if this is a generic r3 bug or if it's specific to my server (Apollo Domain/OS "share mode"). If you have this bug, the symptom is that you get an X protocol error, usually BadAccess, when you go from a page with an inline image to one without. The error happens as the html widget tries to free the color map entries for black and white. The fix is simple. Just don't allocate any cells on a mono display. Use BlackPixel and WhitePixel instead. It seems to me that Mosaic should suffer from the same bug, but I haven't tried it. Let me emphasize that the bug is in the server, not in chimera, and this patch is just a workaround. I think the "right" thing to do is make this behavior contingent on an X resource, but I don't want to fool with it. I suppose it ought to at least be #ifdefed. There is a remote chance that this is the "right" thing in any case, but I'm not enough of a color map expert to know. % diff -c HTMLimages.c- HTMLimages.c *** HTMLimages.c- Thu Nov 18 15:19:02 1993 - --- HTMLimages.c Wed Feb 2 22:38:02 1994 *************** *** 164,169 **** - --- 164,178 ---- static int have_colors = 0; int NumCells; + if (XDisplayCells(dsp, DefaultScreen(dsp)) <= 2) + { + colr->pixel = (colr->red + colr->green + colr->blue > 98304) ? + WhitePixel(dsp, DefaultScreen(dsp)) : + BlackPixel(dsp, DefaultScreen(dsp)) ; + XQueryColor(dsp, colormap, colr); + return; + } + match = XAllocColor(dsp, colormap, colr); if (match == 0) { ------- Message 13 Received: from ACASUN.ECKERD.EDU by JIMI.CS.UNLV.EDU id aa25577; 3 Feb 94 12:11 PST Received: by acasun (5.0/SMI-SVR4) id AA13327; Thu, 3 Feb 94 15:09:40 EST Date: Thu, 3 Feb 94 15:09:40 EST From: Jonathan Roy Message-Id: <9402032009.AA13327@acasun> To: bug-chimera@cs.unlv.edu, thoth@lightning.cis.ufl.edu Content-Length: 414

You probably just need to tell Chimera where this file is located. There are two ways to do this: 1) compile it in by modifying src/conf.h 2) or change the contentFile resource (the quick way) Put the following line in the Chimera app-defaults file: *contentFile: /path/content path is where you installed your content file (/usr/local/infosys/lib ?). You can also set the home page and the help document this way: *homePage: /path/home.html *helpDocument: /path/help.html You can test the resources by using the xrdb command: xrdb -merge *contentFile: /path/content ^D I hope this helps. -john ------- Message 17 Received: from CSTEAM.COM by JIMI.CS.UNLV.EDU id aa23420; 6 Feb 94 11:34 PST Received: from csteam.com by csteam.com with SMTP id AA26595 (5.67a/IDA-1.5 for ); Sun, 6 Feb 1994 14:35:40 -0500 Message-Id: <199402061935.AA26595@csteam.com> To: John Kilburg Cc: bug-chimera@cs.unlv.edu Subject: Re: html displayed In-Reply-To: Your message of "Sun, 06 Feb 1994 08:04:24 PST." <199402061611.AA24786@csteam.com> Date: Sun, 06 Feb 1994 14:35:39 -0500 From: George Boyce Thanks!

If the Print button is pressed for a second time without a request having been made or the Requester window cancelled then MakeRequester Error 1 is printed on stdout and nothing happens to the Requester window. The behaviour should be to map and raise the Requester window (by calling XMapRaised) - it is easy to get interrupted and temporarily lose a window somewhere on the screen. The Save operation should behave similarly. At the moment popping up the Requester makes the Save button insensitive, which is inconsistent with Print. Please don't cure the inconsistency by making Print insensitive! Same goes for Search. The MakeRequester error is also reported if Print is selected while the Save requester is up. Unless they use the same popup I would expect either to be usable independently of the other, i.e. click Print, change mind, click Save, and do so without having to get rid of the Print Requester window first. If they are the same popup with just different labels and callbacks then it should be possible to flip between the different manifestations in the mapped state. It is not obvious what the default is when saving by hitting Return after entering a filename. I think it would be better to have a "one of many" group of radio buttons, plus a Save button, instead of the Command buttons. Then for the future a nice touch would be to have the initial state settable via a resource so that entering a filename and hitting Return gets me the document in my preferred format. I would prefer the last filename entered in the Requester not to be cleared out when it is popped up again. After all I might want to save the next document in the same directory and it is a hassle typing it all in again. It is much easier to delete the old contents than it is to retype. What do others think? Mostly these are not major issues but I think they are important from a user interface point of view, and would make chimera more pleasant to use.

It's easy to see why gopher is broken. 'selector' is used before it's set in gopher_main(). I think you need to add something like selector = alloc_string(filename); near the top of the routine. It was there in 1.38 but is missing now.

It does prevent the core dump, but it still will not work with a short gopher url of the form gopher://machine.site.dom or gopher://machine.site.dom/. It will accept either format if I put the port number on it, eg. gopher://machine.site.dom:70. I believe it should try a default port of 70 if one is not specified. This would be consistent with the behavior of other www browsers.

In order to compile on Solaris 2.3, I had to add the following lines right after the includes in src/net.c: #ifdef SYSV # define bzero(dst,len) memset(dst,0,len) # define bcopy(src,dst,len) memcpy(dst,src,len) #endif /*SYSV*/ I shamelessly stole the defines from pbmplus/pbmplus.h. Speaking of which, I would change the lines near the top of that file that read: #if defined(USG) || defined(SVR4) #define SYSV #endif to read: #if defined(USG) || defined(SVR4) # ifndef SYSV # define SYSV # endif #endif This cleans up a rather harmless redefine warning for Solaris. I can't test these against other SYSV's, but I believe they would need them too.

Stewart Ellis", Tue, 08 Feb 94 15:28:32 EST Jim, how would one go about trying to get the entries into sorted order? That's a good idea, and it wouldn't be hard, just a bit of grunt coding. You would split the loop in ftp_dir() into two parts. The first would read entries out of the buf into bits of storage allocated with alloc_string(), and make a list of the bits (one for each file in the directory). The list would have to be malloc/realloced, or an initial pass would have to be made to determine how many entries there are. The second part would call qsort() on the list, passing strcmp() as the comparison routine, then build the html. I'm glad you've volunteered for this. I'm looking forward to seeing the code. By the way, it would also be fun to switch back to LIST (with a fallback to NLST if the result can't be parsed), and do something with the info that comes back. You could put up file/dir icons like the gopher display does, and list the size of the files. ------- Message 46 Received: from citi.umich.edu by JIMI.CS.UNLV.EDU id aa26941; 8 Feb 94 13:39 PST Received: from citi.umich.edu by citi.umich.edu with SMTP; Tue, 08 Feb 94 16:38:09 -0500 From: Jim.Rees@umich.edu To: bug-chimera@CS.UNLV.EDU Date: Tue, 08 Feb 94 16:38:09 EST Subject: Re: chimera 1.46 - good!

I guess what I mean is that the full set of choices is only appropriate for html and maybe plain text files.

Going through gif works since gif quantizes to 256 colors, but it's not a good solution. I quantize to 16 colors for grayscale, since my grayscale displays are all 4 bit, and to 50 for color, which is what Mosaic uses. One problem is that you'll get a different 50 colors for each image, so if you have lots of inlines on a page, you might still run out. For grayscale, the quantization should be done after converting to grayscale instead of before, but I haven't done that yet. It hasn't been a problem.

Chimera always uses binary mode like Jim says. >2) there are lots of format choices, the html button is the one I >chose, but I did not get a useful file (my guess is the answer to 1 >is no). I will try to clarify this...when you click on "HTML" it takes the raw HTML and sends it to the printer (for the printer command) or put its in a file (for save the command). If you want to print raw HTML to the printer then you will need to save it first as HTML then convert it to postscript (assuming you have a postscript printer) and then send it to the printer. If you click on postscript then the HTML is converted to postscript and chimera either saves it or sends it to the printer (depending on the command). Something tells me I need to write better docs. I am considering adding capabilities to the content file which would do the conversion automatically. What do you guys think? >1) can chimera ftp in binary for appropriate extensions? >2) could the dialog be different for binary files to cut down on the >confusion?, or >3) could we have a binary transfer mode? You can force an ftp-like download by clicking on the anchor with the middle button instead of the left mouse button. If you look in the content file there are extensions which are "unknown". If you attempt to grab one of these types of files Chimera will ask for a filename and save it directly. If there are extensions that have been missed then add them to your content file and send them to me so that they will be included in the next release. I will test these abilities tonight hopefully to make sure they work. I think they worked at one time. By the way, tonight I plan to release a version which fixes the "little" bugs since 1.46 (including the WWW_HOME patch).

I am not a real programmer, so may not understand all the issues well enough to comment on the code, but this seems like a good idea. I use chimera mostly over a term link from Sun to Sun. I suspect that lots of term, slip, ppp (and slap if it is ever released) will use chimera, and this will help all of us.

I have been experiencing a problem whenever I try to connect to a host that is unavailable, then exit chimera, then later reconnect chimera and select an item from the home page. It tries to connect to the unsuccessful url from the previous failed attempt and reports an error. If I try again, then I am successful.

Maybe nothing. But (2) on delayed images: Mosaic has a scheme for making sure that the image cache doesn't grow too large. I haven't looked at all the code, and don't know whether I've done all the necessary hooks for that to work. If not, the result could be excessive and growing memory use. (3) on caching images: (a) There probably needs to be better control over when images are written to the disk. You don't want to save every image permanently. When you go exploring at some site, you don't want to save all of their images permanently. But you probably want better control than I've got. The best thing would probably be a button that says to save all of the images from the current document. This would replace the current -c option, which causes every image seen in the session to be saved. (b) Some thought needs to be given to the file names. Probably it should be a translation of the URL. (It can't be the URL itself, because that contains slashes, which are not legal in filenames.) I didn't do that because I'm running on an old file system that only allows 30-character filenames, and the URL's are typically longer than that. (c) This option needs to interact properly with delayed images. The routine that checks whether we already have an image should also check the cache on disk. Even if delayed loading is set we probably want to see images that we've already got on disk. ------- Message 70 Received: from klinzhai.rutgers.edu by JIMI.CS.UNLV.EDU id aa25853; 12 Feb 94 10:15 PST Received: from geneva.rutgers.edu by klinzhai.rutgers.edu (5.59/SMI4.0/RU1.5/3.08) id AA00688; Sat, 12 Feb 94 13:15:32 EST Received: by geneva.rutgers.edu.lcsr (5.0/SMI-SVR4) id AA09383; Sat, 12 Feb 1994 13:15:44 +0500 Date: Sat, 12 Feb 1994 13:15:44 +0500 From: Charles Hedrick Message-Id: <9402121815.AA09383@geneva.rutgers.edu.lcsr> To: Jim.Rees@umich.edu Subject: Re: various changes Cc: bug-chimera@cs.unlv.edu Content-Length: 625 Oops.

There is actually an http header that gives the length of time a doc should be cached, but I don't think any browsers use it. Here's my version, inspired by (and somewhat copied from) Charles's. It has the advantage that it caches after the doc conversion, so cached images don't have to go through the external giftoppm program. It's slightly more immune to name collisions, but is not production code -- it could use some cleanup and more error checking.

There are a couple of oddities in the way the Path= looks, e.g. Path=GET /path/ HTML/1.0. When I set up the link this way, the gopher2.011 client, using lynx as its html viewer, can parse this, as can Mosaic and lynx by itself, directly accessing the gopher server. Xgopher pukes horribly (no html support at all). Chimera retrieves the info as a properly formatted text file containing html, but refuses to parse the contents. I do not understand the parts of chimera that cause a given text stream to be interpreted or not. This seems conceptually similar to the problem of ftp link information retrieved from a gopher looking like perfectly good gopher pages, but not getting interpreted. Am I off base in thinking that?

The gopher protocol provides for HTML with the 'h' prefix code but I do not think Chimera uses this (minor oversight :). If this is so then I will fix it. The real answer is for everyone to move to the new gopher (2.x) and new HTTP (1.x) servers which provide Content-type information. One problem with the 1.x gopher servers is that they only have that one letter prefix code to identify the file type. The codes that the gopher guys selected were lame and did not specify many file types. Also, the gopher server cuts off the file extensions so that information can't be used. I think the magic thing is a bad idea since the newer servers provide file type information. Also, it is not 100% accurate. -john ------- Message 74 Received: from mayall.CS.UNLV.EDU by JIMI.CS.UNLV.EDU id aa08433; 14 Feb 94 16:30 PST To: bug-chimera@mayall.CS.UNLV.EDU Subject: chimera 1.47 Date: Mon, 14 Feb 1994 16:30:08 -0800 From: John Kilburg Here are the changes I've made so far: 1.47 - ---- Fixed problem in SubmitForm (main.c) so that it handles the isindex stuff correctly.

It also made compilation on SYSV machines work better. Changed main.c so that the command line URL is used before the URL specified by WWW_HOME. Benno Blumenthal benno@ldgo.columbia.edu Put alternate resources in src/Chimera.ajs.ad. ajs@merck.com Fixed unbelievably poorly written mystrcmp and mystrncmp. Grrr. Fixed the '..' code in url.c.

This problem cropped up after I made the user interface changes. I am working on this now. Once I finish it I will run through some tests and then release 1.47. Mostly these are small fixes because I've been busy lately. Also, I've been waiting a bit to make sure no other serious problems were found in 1.46. It would be nice if you guys could send me URLs to use for testing. The easiest way, I think, is to mail me your bookmark file. -john ------- Message 75 Received: from nova.gmi.edu by JIMI.CS.UNLV.EDU id aa11489; 14 Feb 94 18:17 PST Received: by nova.gmi.edu (4.1/SMI-4.1-DNI) id AA07731; Mon, 14 Feb 94 21:19:33 EST From: "R.

The first is the odd glitches in the scrolling area after viewing a pic or doc. On closer observation, it seems to often have the same couple of inches (vertical) of pixels replicated. What is even worse is that if I selected something from the scrolling widget (I am unsure of the proper terms for X stuff) which was scrolled down halfway, then scroll the item I selected to a different area, then when I go BACK the original doc is scrolled to a new spot. This is on Solaris 2.3 with OW 3.3, which is X11R5.

It was handling negative port numbers wrong. Fixing it lets me get at the movie database. By the way, negative port numbers are illegal, but they are still important, because the various protocol routines use port -1 to indicate the default for that transport. However, there is still another bug somewhere. Some of the images don't work, and the url display at the top has a -1 port number. I'm looking at Jeff Abramson's fix now. I'm not convinced it's right but I'll give it a try. *** url.c- Sun Feb 13 00:33:12 1994 - --- url.c Thu Feb 17 11:31:02 1994 *************** *** 510,522 **** */ if (url[i] == ':') { ! for (digit_count = 0, i++, p = 0; ! isdigit(url[i]) || url[i] == '-'; i++) { p = p * 10 + (url[i] - '0'); digit_count++; } if (url[i] != '/' && url[i] != '\0') { - --- 510,533 ---- */ if (url[i] == ':') { ! int isign = 1; ! ! i++; ! ! if (url[i] == '-') ! { ! isign = -1; ! i++; ! } ! ! for (digit_count = 0, p = 0; ! isdigit(url[i]); i++) { p = p * 10 + (url[i] - '0'); digit_count++; } + p *= isign; if (url[i] != '/' && url[i] != '\0') { ------- Message 98 Received: from gw1.att.com by JIMI.CS.UNLV.EDU id aa20774; 17 Feb 94 9:53 PST Received: by emsr0.emsr.att.com (4.1/EMS main.cf 1.33 7/21/93 (SMI-4.1/SVR4)) id AA03475; Thu, 17 Feb 94 12:49:08 EST Received: from emsr1.emsr.att.com by emsr0.emsr.att.com (4.1/EMS main.cf 1.33 7/21/93 (SMI-4.1/SVR4)) id AA03464; Thu, 17 Feb 94 12:49:07 EST Received: by emsr1.emsr.att.com (4.1/EMS main.cf 1.33 7/21/93 (SMI-4.1/SVR4)) id AA05942; Thu, 17 Feb 94 12:57:01 EST Received: from cnvnjb.jazz.att.com by emsr1.emsr.att.com (4.1/EMS main.cf 1.33 7/21/93 (SMI-4.1/SVR4)) id AA05928; Thu, 17 Feb 94 12:56:58 EST Received: by cnvnjb.jazz.att.com (4.1/SMI-4.1) id AA01712; Thu, 17 Feb 94 12:52:06 EST From: Jeff Abramson Message-Id: <9402171752.AA01712@cnvnjb.jazz.att.com> Subject: Re: Chimera-1.46 patches To: "R.

I still don't understand why no one else is having any trouble with it. It doesn't look to me like it would work the way it was. Here's the whole thing, including my previous fix for ParseURL(). There is also another fix to ParseURL() here. If the port is -1, it isn't really a port.

Currently config uses sed to search for the target XAWLIB in Common.tmpl.dist, and substitutes the new config value and redirects to Common.tmpl. But XAWLIB does not exist in C.t.dist. I believe if we were to simply put an "XAWLIB=" line at the bottom of the dist version, that would null out XAWLIB in the makefiles. I am very poor with sed, to the point of writing C programs to avoid sed sometimes, but if the XAWLIB value could be replaced for the end of the file, or catted onto the end that would solve that problem.

One of the config options is to enable PASV. Since DEC and some other vendors do not support PASV, what are the advantages to it that some ftp client packages only support PASV?

If I have the term socket stuff compiled into a program like ncftp, xgopher, Mosaic, chimera, irc, and maybe a few others that I am not thinking of at the moment, I can execute the program on a non-internet connected machine with internet i/o being handled at the other end of the socket on my internet machine.

I poked around a bit and found the following behaviour in http.c: http(). http does a net_read. If the connection is dead, the remote term sends a C_CLOSE message (i.e. an @2), however the link has been switched to C_DUMB, so it doesn't see the control message (I'm guessing here). Anways, net_read returns a string of length 4: @<2\0, chimera says "4 bytes read" and hangs forever in the next read. A simple hack is to put the following code in http.c: (around line 202) #ifdef TERM if( tlen == 4 && !strcmp(buffer,"@>2")) { free(t); d->text = NULL; d->error = alloc_string("

Info

Could not connect to server."); d->type = DocInternal; net_close(s); return; } #endif I suppose there are other places in the code where such things should be done - perhaps in net_read itself, having it return 0 (-1?) if it gets the C_CLOSE control string. I couldn't figure out a nice way to get a "Dead server" message to work for this case, but then I don't know the code that well.

John incorporated the fix into 1.48, but if you really want to stay with 1.47, here it is again. % diff -c ../../../chimera-1.47/src/src/http.c http.c *** ../../../chimera-1.47/src/src/http.c Thu Feb 17 10:19:18 1994 - --- http.c Fri Feb 18 03:56:42 1994 *************** *** 116,122 **** */ if (methodname == MethodGET) /* GET */ { ! query = alloc_string_mem(strlen(filename) + strlen(format_get) + strlen(ext) + 1); if (query == NULL) { net_close(s); - --- 116,123 ---- */ if (methodname == MethodGET) /* GET */ { ! query = alloc_string_mem(strlen(filename) + strlen(format_get) + ! strlen(ext) + 1); if (query == NULL) { net_close(s); ------- Message 139 Received: from hubert.CS.UNLV.EDU by JIMI.CS.UNLV.EDU id aa24967; 26 Feb 94 23:10 PST To: bug-chimera@hubert.CS.UNLV.EDU Subject: Chimera 1.49 Date: Sat, 26 Feb 1994 23:10:22 -0800 From: John Kilburg has been released. ftp://ftp.cs.unlv.edu/pub/chimera/chimera-1.49.tar.gz I didn't fix some gopher stuff that I wanted to fix but I was getting complaints about an annoying new bug which was easy to fix. I guess I should have released a patch for it. Anyways, give it a try. It should be less annoying than 1.48. -john ------- Message 140 Received: from cheviot.ncl.ac.uk by JIMI.CS.UNLV.EDU id aa12896; 28 Feb 94 4:10 PST Received: from ncl.blagdon (blagdon.ncl.ac.uk) by cheviot.ncl.ac.uk id (5.65cVUW/NCL-CMA.1.35 for ) with SMTP; Mon, 28 Feb 1994 12:09:54 GMT From: Jim Wight Date: Mon, 28 Feb 94 12:09:52 GMT Message-Id: To: bug-chimera@cs.unlv.edu Subject: Is this right? Reply-To: J.K.Wight@newcastle.ac.uk When a Form uses the POST method chimera displays the transmitted data in the URL as if the method were GET. There is nothing to stop the user saving the URL as a bookmark, which, when they come to use it later, probably won't work because the CGI program is likely to be expecting its input on standard input only. Should the URL be displayed as it is? Should the URL be savable as a bookmark? I don't know enough to have an opinion on what the answers should be.
