What would be a better solution, I've wondered? Here's a proposal for one I think fits in much nicer. Find basically does the following job: Walk a set of specified directory trees, apply a set of predicates to the contents, and perform some action if the result is true. However, find could be thought of as a pipeline of filters that operate on a stream of filenames; discarding some that don't find some criteria, and printing the rest to the next stage. The final stage of the pipeline performs some action, such as printing the file names or making them arguments to some command. So, I wrote two commands: walk, and sor. Walk walks over a directory tree, printing it's contents, possibly with quoting in the style of the new "%q" format (using ls's ``lsquote'' routine), and possibly with a limitation on the depth to which it'll descend. Sor (Stream OR, get it?) is an rc script that reads a set of filenames from it's input, and applies a set of tests to them, echoing those names that pass a test, discarding the rest. The effect is that one can now create arbitrary pipelines that mimic what find does under Unix, only are much more flexible. It isn't the fastest thing in the world, but it works, and seems to work pretty well. Now, I think sor is genuinely useful, but why walk when we have du -a? Two reasons. (1) du is the program to collect disk usage statistics, not the program to do general walks of a file tree. As such, it misses a feature to limit depth, and contains logic to make sure it doesn't ``count'' a file twice. That's useful for du, but not really for a general file walker; what if I want to see all names of a file? What if I want to look for multiple names with the same qid? It certainly makes no sense to augment du with that functionality: du is the disk usage summarizer, not the general file tree walker. Also, not being able to limit the depth of one's search can be annoying. What if I want to look for a file, but only in the first three levels of a hierarchy? It can be argued that it might be useful to summarize the disk usage information of everything up to n levels in a hierarchy, but I'd argue that that's not generally useful enough to warrant a change to du. Besides, what if I wanted to find all the names of a given file within n levels in a hierarchy? It could be argued that du could be used along with some clever sed script to achieve the effect of depth limiting, but we still loose the ability to see a file more than once. Hence walk. Anyway, I append both here in case others find them useful. It'd be nice to see them go into the distrubition if there's enough general appeal (and if they don't suck too badly). In any event, some feedback on the idea and the tools would be nice. - Dan C. ------- =_aaaaaaaaaa0 Content-Type: text/plain; charset="us-ascii" Content-ID: <6479.1036099195.2@augusta.math.psu.edu> /* * Walk a directory tree, in the style of du(1), * but with some additional flourishes. * * Dan Cross */ #include #include static int mkdepth(int); static char *mkname(char *, int *, char *, char *); static void walk(char *, int, int); static void walkname(char *, int, int); static int walkquote(int c); char *fmt; void main(int argc, char *argv[]) { char *dir; int depth; Dir *d; dir = "."; fmt = "%s\n"; depth = -1; ARGBEGIN { case 'd': depth = atoi(ARGF()); break; case 'q': quotefmtinstall(); doquote = walkquote; fmt = "%q\n"; break; }ARGEND if (argc == 0) walkname(".", depth, 1); else { for (dir = *argv; dir; dir = *++argv) { if ((d = dirstat(dir)) == nil) { fprint(2, "dirstat %s: %r\n", dir); continue; } walkname(dir, depth, d->mode & DMDIR); free(d); } } exits(0); } /* Cribbed from ls(1) source. */ static int walkquote(int c) { if (c <= ' ' || strchr("`^#*[]=|\?${}()'", c)) return(1); return(0); } static void walkname(char *dirname, int depth, int isdir) { int fd; if (strcmp(dirname, ".") != 0 && strcmp(dirname, "..") != 0) print(fmt, dirname); if (isdir) { fd = open(dirname, OREAD); if (fd < 0) { fprint(2, "open %s: %r\n", dirname); return; } walk(dirname, fd, depth); close(fd); } } static char * mkname(char *name, int *l, char *basename, char *filename) { char *nname; int t; t = strlen(basename) + 1 + strlen(filename) + 1; if (*l == 0 || name == nil) { *l = t; name = malloc(t); if (name == nil) sysfatal("malloc %d: %r\n", l); } else if (*l < t) { nname = realloc(name, t); if (nname == nil) { free(name); sysfatal("malloc %d: %r\n", l); } *l = t; name = nname; } snprint(name, t, "%s/%s", basename, filename); cleanname(name); return(name); } static int mkdepth(int depth) { return((depth == -1) ? depth : depth - 1); } static void walk(char *dirname, int fd, int depth) { Dir *dir, *dp; char *name, *nname; int i, l, n, t; if (depth == 0) return; l = 0; name = nil; n = dirreadall(fd, &dir); for (dp = dir, i = 0; i < n; dp++, i++) { if (strcmp(dp->name, ".") == 0 || strcmp(dp->name, "..") == 0) continue; name = mkname(name, &l, dirname, dp->name); walkname(name, mkdepth(depth), dp->mode & DMDIR); } free(dir); if (name != nil) free(name); } ------- =_aaaaaaaaaa0 Content-Type: text/plain; charset="us-ascii" Content-ID: <6479.1036099195.3@augusta.math.psu.edu> #!/bin/rc rfork e fn runtests { file=$1; shift while (! ~ $#* 0 && ! eval $1 ''''^$file^'''') shift if (! ~ $#* 0) echo $file } while (file = `{read}) { runtests $file $* } ------- =_aaaaaaaaaa0-- From cse.psu.edu!9fans-admin Fri Nov 1 06:32:58 JST 2002 remote from ar Received: from vega.aichi-u.ac.jp ([202.16.124.3]) by ar; Fri Nov 1 06:32:58 JST 2002 Received: (qmail 24831 invoked by uid 1020); 1 Nov 2002 06:32:47 +0900 Delivered-To: arisawa@aichi-u.ac.jp Received: (qmail 24827 invoked from network); 1 Nov 2002 06:32:46 +0900 Received: from psuvax1.cse.psu.edu (HELO mail.cse.psu.edu) (130.203.4.6) by vega.aichi-u.ac.jp with SMTP; 1 Nov 2002 06:32:46 +0900 Received: from psuvax1.cse.psu.edu (psuvax1.cse.psu.edu [130.203.30.6]) by mail.cse.psu.edu (CSE Mail Server) with ESMTP id 7978C19A6B; Thu, 31 Oct 2002 16:32:42 -0500 (EST) Delivered-To: 9fans@cse.psu.edu Received: from mailnw.centurytel.net (mailnw.centurytel.net [209.206.160.237]) by mail.cse.psu.edu (CSE Mail Server) with ESMTP id 30AB619981 for <9fans@cse.psu.edu>; Thu, 31 Oct 2002 16:31:10 -0500 (EST) Received: from term4e (pppoe2231.gh.centurytel.net [64.91.54.239]) by mailnw.centurytel.net (8.12.6/8.12.6) with SMTP id g9VLV846015200 for <9fans@cse.psu.edu>; Thu, 31 Oct 2002 13:31:08 -0800 (PST) Message-ID: To: 9fans@cse.psu.edu Subject: Re: [9fans] rc on U/WIN?

I forgot to say how to use these. Sorry, my bad. Basically, compile walk and put it and sor in your bin directories. Walk takes ``-d n'' to limit the depth of the walk to the nth level in the target directory (walk -d 0 prints nothing), and ``-q'' to quote the output in the style of ls(1). These can of course be used in concert. For example, `walk -d 3 -q /dev' prints out everything up to 3 levels deep in /dev, quoting everything that needs to be. `walk -d 3 -q /dev /env' might be a better demonstration, as I think it's a rare thing indeed that something in /dev needs to be quoted. Sor works sort of like grep, except that you pass it tests. For instance, `walk -d 3 -q /dev /env | sor 'test -d' '' will print out the names of all the directories up to depth 3 in /dev and /env. Multiple tests can be put on the same line, effectively creating a logical `or' operator. For example, walk -d 3 -q /sys/lib | sor 'test -d' 'test -x' (interestingly, this shows /sys/lib/ghostscript/font/mkfile is executable on my system; how odd.) Of course, the usual combinations with grep, sed, etc, will work. A few Unix find idioms and their translations are: unix% find $home -name '*foo*' -print term% walk $home | grep foo unix% find $home -name '*foo*' -type d -print term% walk $home | grep foo | sor 'test -d' unix% find $home '(' -name '*foo*' -o -name '*bar*' ')' -type d -print term% walk $home | grep '(foo|bar)' | sor 'test -d' unix% find $home/* $home/*/* -prune '(' -name '*foo*' -o -name '*bar*' ')' -type d -print term% walk -d 2 $home | grep '(foo|bar)' | sor 'test -d' unix% find $home -name foo.c -exec ls '{}' ';' term% ls `{walk $home | grep '^foo.c$'} Incidentally, sor internally sets the environment variable ``file'' to the name of the current file being examined. This can be useful for some tests. For example: term% walk -d 1 | sor '/sys/lib/texmf/bin/386/newer $file' Which is basically a goofy way of printing the names of files in the current directory. Or the perhaps more useful: term% walk -d 1 | sor 'grep README $file > /dev/null' Which is a goofy way of doing: grep -l README `{walk -d 1} Anyway, further examples exist, but already the combination of walk and sor is just as expressive, but a lot shorter and simpler than find, et al. Also, it's easy to write other programs that perform tests similar to the rest of the find predicates (I have some simple scripts, for instance, that pull the size and owner/group of a file out of ls -l's output). - Dan C.

I find it's a little too good. FINGERS: "lc" MOUTH: "Damn!" I'm also thinking of rewriting some of the little tools I use so they work relatively well whether I'm on Linux or Windows or Plan 9 (much like Dan missing 'find') and I don't care for bash as much as I used to. I like rxvt on Windows (when I'm stuck on Windows) because X-style copy & paste is hard for me to unlearn (I always want to stop and read the menus in rio/9term, and I reflexively try to use the history when I'm busy), and it just seems natural to want to replace bash with rc so I can just keep copying & pasting my way through life.

In text mode, the keyboard handler seems to be a little erratic. In RIO no problems seem to occur. The behaviour seems to be caused by the occasional backspace and consists of the addition of spurious characters that are not echoed to the screen. Hard to describe, even harder to pinpoint. The most common situation is an invalid command name or command argument value that has a space or some other character in it not present in the command line itself. It is frequent enough to be a bit of a bother on an auth or cpu server. I can't recall if I ever encountered on the FS. I think the problem appeared in 4th Edition, I can probably check later this month. Hm, I haven't ever checked if switching to VGA mode makes a difference or not. 2. My Intellimouse seems to be misunderstood: the right button quite regularly starts duplicating the middle button function in RIO, SAM and ACME; a wloc command in any window restores it to its more useful behaviour. I only noticed this recently, I'm using a stand-alone workstation with the second ISO image (the one I asked Russ about a few days before its recent release - I think it's current, send me a digest and I'll compare). 3. I started getting vncv lockouts so I switched to a newer workstation, keeping the disks unchanged and the lockouts as well as frequent vncv failures have stopped. I find this quite baffling, but not unexpected. I also have a Gygabyte motherboard that seems incapable of handling any OSes like Plan 9, NetBSD or WinNT that need real memory protection. I think it's MMU related. Hm, could be CPU-related, too, the chip is Cyrix/IBM rather than Intel, but I think I tried a different CPU once. Can't think of anything else presently, I may follow up on this if I recall or encounter any other small issues that one can easily live with. ++L From cse.psu.edu!9fans-admin Fri Nov 1 14:07:17 JST 2002 remote from ar Received: from vega.aichi-u.ac.jp ([202.16.124.3]) by ar; Fri Nov 1 14:07:17 JST 2002 Received: (qmail 3128 invoked by uid 1020); 1 Nov 2002 14:07:15 +0900 Delivered-To: arisawa@aichi-u.ac.jp Received: (qmail 3124 invoked from network); 1 Nov 2002 14:07:14 +0900 Received: from psuvax1.cse.psu.edu (HELO mail.cse.psu.edu) (130.203.4.6) by vega.aichi-u.ac.jp with SMTP; 1 Nov 2002 14:07:14 +0900 Received: from psuvax1.cse.psu.edu (psuvax1.cse.psu.edu [130.203.4.6]) by mail.cse.psu.edu (CSE Mail Server) with ESMTP id CC45119A7A; Fri, 1 Nov 2002 00:07:06 -0500 (EST) Delivered-To: 9fans@cse.psu.edu Received: from collyer.net (adsl-63-192-14-226.dsl.snfc21.pacbell.net [63.192.14.226]) by mail.cse.psu.edu (CSE Mail Server) with SMTP id AF88819A75 for <9fans@cse.psu.edu>; Fri, 1 Nov 2002 00:06:47 -0500 (EST) Message-ID: <0394cbfb2c4ecc3d90d0b2a8d9f8bf20@collyer.net> To: 9fans@cse.psu.edu Subject: Re: [9fans] Niggles From: Geoff Collyer MIME-Version: 1.0 Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit Sender: 9fans-admin@cse.psu.edu Errors-To: 9fans-admin@cse.psu.edu X-BeenThere: 9fans@cse.psu.edu X-Mailman-Version: 2.0.11 Precedence: bulk Reply-To: 9fans@cse.psu.edu List-Id: Fans of the OS Plan 9 from Bell Labs <9fans.cse.psu.edu> List-Archive: Date: Thu, 31 Oct 2002 21:06:28 -0800 I've seen the invisible spurious character business on CPU server consoles with the serial console enabled, but while typing on the PS2 keyboard and watching the CGA display.

It's now also possible to change FIXEDSIZES in /sys/src/fs/*/9*.c rather than having to edit dev/juke.c before compiling each distinct kernel. The way it used to work was that DSIZE was the size in RBUFSIZE-byte blocks of each optical disc *side*. However, it is possible to use discs of different sizes within a single jukebox: you set FIXEDSIZES to 0 and pay with a delay at each boot while the file server pulls each disc side in and asks the drive how big it is. It's probably wiser to use discs of the same size and set FIXEDSIZES to 1, which makes the file server just look at one disc and assume that all the sides are the size of its. So DSIZE was only used for computing the statistics that "statw" prints on the console, for working out sizes in the cache save and restore commands, and in the implementation of "check touch". Those operations could be led astray if DSIZE wasn't the size in Plan 9 blocks of all the optical discs in all jukeboxes on a given file server. If one wanted to put a jukebox with 5.2GB discs and one with 2.6GB discs on the same file server, it wouldn't work perfectly. DSIZE is gone. It's now possible to mix jukeboxes with discs of different sizes, and even, if you're willing to put up with the delays, to use discs of different sizes within a single jukebox, and everything should now work right. The whole thing compiles but I want to test it tomorrow (after the third jukebox arrives) before I offer the code to anyone else.

I'm not sure, but possibly. I'm involved in starting a company built around various sorts of 24/365 on-call and contract IT and programming services built around Open Technology. Plan 9 and Inferno will feature in that to a significant degree. The company is In Silica, LLC. Though it will operate under a DBA (Open Forge). The Hangar 18 project is only one of the things we've got going. Our focus is on reliable distributed computing, global sign on, business informatics & automation. If all went well the paperwork hit the state's desk this afternoon. Should be in business (technically) sometime next week. If you would like more details please contact me directly. -- ____________________________________________________________________ We don't see things as they are, ravage@ssz.com we see them as we are. www.ssz.com jchoate@open-forge.org Anais Nin www.open-forge.org -------------------------------------------------------------------- From cse.psu.edu!9fans-admin Sat Nov 2 08:31:17 JST 2002 remote from ar Received: from vega.aichi-u.ac.jp ([202.16.124.3]) by ar; Sat Nov 2 08:31:17 JST 2002 Received: (qmail 19399 invoked by uid 1020); 2 Nov 2002 08:31:16 +0900 Delivered-To: arisawa@aichi-u.ac.jp Received: (qmail 19395 invoked from network); 2 Nov 2002 08:31:16 +0900 Received: from psuvax1.cse.psu.edu (HELO mail.cse.psu.edu) (130.203.4.6) by vega.aichi-u.ac.jp with SMTP; 2 Nov 2002 08:31:16 +0900 Received: from psuvax1.cse.psu.edu (psuvax1.cse.psu.edu [130.203.4.6]) by mail.cse.psu.edu (CSE Mail Server) with ESMTP id 46A0B19A59; Fri, 1 Nov 2002 18:31:07 -0500 (EST) Delivered-To: 9fans@cse.psu.edu Received: from unicorn.math.spbu.ru (unicorn.math.spbu.ru [195.19.226.166]) by mail.cse.psu.edu (CSE Mail Server) with ESMTP id BF12319A06 for <9fans@cse.psu.edu>; Fri, 1 Nov 2002 18:30:40 -0500 (EST) Received: (from vugluskr@localhost) by unicorn.math.spbu.ru (8.9.3/8.9.3) id CAA30935 for 9fans@cse.psu.edu; Sat, 2 Nov 2002 02:30:39 +0300 From: "Roman V.

The dot-com bubble burst and many of the customers couldn't pay their bills, and some people thought that there weren't going to be many new customers. There was also political maneuvering by competing groups within the company. I forget the exact timing; I think PathStar was cancelled in late 2000; certainly no later than March 2001. I thought PathStar was Lucent's last hope, but apparently management thought that people are going to buy 7R/Es (the follow-on to the 5ESS). If they couldn't afford PathStars, which were relatively inexpensive, they certainly won't be able to afford 7R/Es (except perhaps used, on ebay, where I see various 5ESS components).

I've tested it with an HP 80EX with 5.2GB discs and an HP 40FX with 2.6GB discs on one file server. I've enclosed the diffs (a little over 200 lines) and a bundle of the changed files. I've done a little other file server work, including incorporating nigel's/forsyth's wormcopy, since I last synced kernels with nemo, but I don't think these changes will be hard to integrate.

I have just been informed by family attorney Barrister Chike Egobia that my late husband operated a secret account with fictitious name in a Nigeria bank into which total sum of Nineteen Million, Five Hundred Thousand US Dollars ($19.5) was transferred and credited in his favour. The attorney now advised me to seek in confidence a foreign account into which this fund could be transferred for disbursement as directed by my late husband in his will. It has been resolved that 25% will be your share for nominating an account for this purpose and any other assistance you will give in that regard. 10% has been mapped out to payback all local and international expenses, which may be, incurred in the transfer process and 5% has been conceded to the local bank manager here assisting facilitating the transfer. Finally, 60% will come to myself and my children and good part of this shall be directed towards executing his will which is to buy shares and stocks in foreign country to securities his childrens future to facilitate the conclusion of this transaction if accepted do send to me promptly by fax through family attorney, the following. 1. The account number to be used for remittance 2. Name and address of your bank 3. Fax and telephone numbers, through which you will be contacted 4. Promptly whenever you attorney/ assistance may be required Please note that i have been assured that the transaction will be concluded in ten (10) banking working days upon my receiving from you the above listed information will commence the process of retrieving the will immediately i hear from you. May at this point emphasize the high level of confidentiality, which this business demands hope you will not betray the trust and confidence, which is reposed in you. However, you may need to give me sufficient assurance that you will not sit on this fund when it is finally remitted into your account. Please direct your reply by email to my box in which the family attorney will communicate with him towards effective completion of this transaction. Regards.

I assume you are talking about `hold mode.' When a window is in hold mode (is blue), none of the input you type is sent to whatever is reading from that console. When you exit hold mode (by typing esc), the input starts flowing again. Hold mode doesn't cause EOFs to be sent, though. You still need to type ^D to send mail an EOF.

Something like: the proxy/firewall device doesn't know the protocol, therefore the IT department wont allow it, which forces the HTTP tunneling, which gives the system/protocol a chance to become popular, which makes it a legitimate protocol and gets it on the vendors' radars, which is then supported, obviating the need for tunneling. > non-http protocols are dangerous. > therefore we'll only allow http. > > only http is allowed. > therefore we'll tunnel everything over http.

This is an oversimplification. The companies that I know that have this problem are actually in a situation where they have an internal network that is not directly routed to the Internet at all, and all traffic must pass through application-layer gateways (aka proxies). The protocols which are proxied tend to vary. But everyone proxies HTTP in this environment. There often isn't an intent to stop the use of other applications; just no resources (time and money) to explicitly enable them. It seems to me like this sort of thing is going away and becoming less common, not more common. (If everyone used Plan 9 and people could just import /net, this problem wouldn't exist... people in these environments would just tunnel everything over 9P! Is this any more acceptable?) > only http is allowed. > therefore we'll tunnel everything over http. So often this is a matter of resources; if the application developer knows that in some situations only HTTP is allowed, but doesn't want to write everything for both cases, said application developer will tend to just do everything over HTTP so that it "just works" for people on weird networks. --jss.

Come on. Buy a router that does ip filtering. They all do. HTTP proxies would have to be changed to admit WebDAV (they added new verbs!), so we're talking about modifications either way. My point was that it makes more sense just to open another port. > (If everyone used Plan 9 and people could just import /net, this > problem wouldn't exist... people in these environments would just > tunnel everything over 9P! Is this any more acceptable?) No, it's not. It would be just as dumb (although more convenient for me) to allow only 9P through a firewall. > > only http is allowed. > > therefore we'll tunnel everything over http. > > So often this is a matter of resources; if the application developer > knows that in some situations only HTTP is allowed, but doesn't want to > write everything for both cases, said application developer will tend > to just do everything over HTTP so that it "just works" for people on > weird networks. If you're actually _using_ HTTP then fine. Tunneling WebDAV over HTTP requires changing all the proxies because you're really speaking WebDAV/HTTP, which bears only a passing resemblance to HTTP. Who says the weird networks are going to allow WebDAV/HTTP through? My point was that it's work either way. It's dumb that WebDAV and friends are trying to pretend that it's not.

Once all the clients have stopped, you can run the new command venti/sync (you'll have to pull to get the one I just installed on sources), which won't return until the write queues have emptied. Of course, they might fill up again after venti/sync returns, but if you stop all the Venti clients and then run venti/sync, you can be guaranteed the queues stay empty afterward. Vac now syncs before exiting, so if vac is your only client, you don't have to worry about ever running venti/sync. As long as your vacs have exited, all the data is on the disk.
