assertion failed; looks like a bug 24 years

Hamish Macdonald

In XEmacs 21.2 (beta32) "Kastor & Polydeukes" [Lucid] (sparc-sun-solaris2.7) of Fri Mar 31 2000 on rhea configured using `configure --prefix=/export/users/hamishm/xemacs --site-prefixes=/export/users/hamishm/gnome:/export/users/hamishm --pdump' CVS updated at 9:10am EST March 31 2000. Please describe exactly what actions triggered the bug and the precise symptoms of the bug: I recently started playing around with eshell by John Wiegley (http://www.emacs.org/~johnw/eshell.html) I'm using version 2.2.1, with a couple of bug fixes for my non-MULE XEmacs: (defun process-coding-system (blug) (cons nil nil)) (defun coding-system-eol-type (coding) nil) I discovered that when attempting to do some piping in eshell (e.g. "ls | head"), my XEmacs was dying. I started to do some investigation. I got the following backtrace: #0 assert_failed (file=0x22bda8 "lstream.h", line=33, expr=0x22bdb8 "RECORD_TYPEP (obj, lrecord_type_lstream)") at emacs.c:2748 #1 0xdace4 in unix_send_process (proc=5188096, lstream=0x37fc00) at lstream.h:33 #2 0x167b38 in send_process (proc=5188096, relocatable=5573876, nonrelocatable=0x0, start=0, len=315) at process.c:988 #3 0x16a2a8 in Fprocess_send_string (process=5188096, string=5573876, from=-24697440, to=-24697440) at process.c:1118 This backtrace is actually somewhat misleading, since the lstream passed in to unix_send_process is perfectly valid. The lstream that is being barfed on in p->pipe_outstream (where p is the process structure referred to by Lisp_Object argument proc. It looks like the problem is that "head" exits before reading all its input (pretty normal for "head", I think). It turns out that the following loop (lines 1148-1158 of process-unix.c) is the culprit: while (Lstream_was_blocked_p (XLSTREAM (p->pipe_outstream))) { /* Buffer is full. Wait, accepting input; that may allow the program to finish doing output and read more. */ Faccept_process_output (Qnil, make_int (1), Qnil); old_sigpipe = (SIGTYPE (*) (int)) signal (SIGPIPE, send_process_trap); Lstream_flush (XLSTREAM (p->pipe_outstream)); signal (SIGPIPE, old_sigpipe); } The following backtrace shows p->pipe_outstream being set to Qnil as part of the above call to Faccept_process_output: #0 deactivate_process (proc=5698048) at process.c:1865 #1 0x169ed8 in remove_process (proc=5698048) at process.c:1878 #2 0x16802c in status_notify () at process.c:1408 #3 0xe0ad4 in execute_internal_event (event=5698048) at event-stream.c:3045 #4 0xdfd84 in Faccept_process_output (process=-24697440, timeout_secs=165, timeout_msecs=3406848) at event-stream.c:2641 #5 0xdaca4 in unix_send_process (proc=5698048, lstream=0x37f600) at process-unix.c:1175 #6 0x167b38 in send_process (proc=5698048, relocatable=5985204, nonrelocatable=0x0, start=0, len=315) at process.c:988 Subsequently, at line 1156, Lstream_flush is called, using XLSTREAM(p->pipe_outstream) as an argument. At this point, p->p->pipe_outstream is no longer an lstream, but is nil; the assertion fails, BOOM. I'm not sure what the correct fix is here. Regards, Hamish.

gutter/tab display oddity, then crash 24 years

John A. Turner

env as in: http://www.xemacs.org/list-archives/xemacs-beta/200003/msg00021.html but 21.2b32, CVS update this AM crashes have decreased significantly since the recent fixes, but I'm still occasionally (once/day?) seeing things like this: or... followed by a crash (often before I can start snapshot, rubberband the region, and grab it) the only stack trace I have is from one of the crashes before the recent fixes (I tried running optimized for a while after the fixes), so I'm thinking that would only confuse matters - so I'll wait until I get a new one to pass on... -- John A.

Re: Package status and some time off 24 years

Please excuse my silence. This week is student advising, and I've had a long line at my door. It's making it difficult to get around to my research work, much less my hobbies. :-) On 30 Mar 2000 at 16:26:29 +0200, Andreas Jaeger <aj(a)suse.de> wrote: > - psgml package needs some testers. I'd like get feedback from Jerry > [1] or somebody else if I've done everything correctly [2]. There's > also the question of the generation of some files which is not > solved yet. The etc/cdtd directory should be wiped. Its current contents are inapplicable to the new version, and they can now be generated at build time anyway. Or can they? When you say the question of generating some files, do you mean the correct contents of etc/cdtd? You need to call sgml-compile-all-dtds at some point, although frankly, I'm not sure what elisp files need to be loaded first before that will work. Certainly psgml and psgml-parse, and maybe psgml-dtd as well. I see that I forgot to update the CATALOG when I did a last-minute update of the XML Schemas DTD. This should be applied: --- xemacs-psgml/etc/CATALOG Mon Mar 27 06:57:47 2000 +++ xemacs-psgml/etc/CATALOG Thu Mar 30 15:33:20 2000 ＠＠ -148,8 +148,8 ＠＠ DTDDECL "-//W3C//DTD XHTML 1.0 Strict//EN" xhtml1.dcl DTDDECL "-//W3C//DTD XHTML 1.0 Transitional//EN" xhtml1.dcl - -- XML Schemas (17 December 1999 Working Draft) -- -PUBLIC "-//W3C//DTD XML Schema 17121999WD//EN" structures.dtd + -- XML Schemas (25 February 2000 Working Draft) -- +PUBLIC "-//W3C//DTD XML Schema 25022000WD//EN" structures.dtd PUBLIC "datatypes" datatypes.dtd -- MathML 2.0 (11 February 2000 Working Draft) -- Otherwise, it looks fine to me. I'm using it to edit some web pages with no apparent difficulties. I should also warn you that I used the DTDDECL construct to identify SGML declarations. However, nsgmls does not have support for DTDDECL, and warns about this ... per instance of a DTDDECL in the CATALOG. The upshot is that if you validate your HTML page with nsgmls, you get a page full of warnings about DTDDECL before anything relevant appears. Expect complaints. (I'm hoping this will motivate someone to add DTDDECL support to nsgmls, or at least make it so it complains once per CATALOG instead of once per DTDDECL.) -- Jerry James Email: james(a)eecs.ukans.edu WWW: http://www.eecs.ukans.edu/~james/

Package status and some time off 24 years

Andreas Jaeger

I tried to release the packages and SUMO tarballs this week but didn't succeed.:-( The current problems are: - xemacs-base is broken for Adrian Aichner (loading of compile fails) on NT and I can't reproduce this on Linux. - psgml package needs some testers. I'd like get feedback from Jerry [1] or somebody else if I've done everything correctly [2]. There's also the question of the generation of some files which is not solved yet. I'm leaving for California on Saturday for three weeks of working. I've got a laptop with the checked out xemacs-packages with me. I hope I can access my emails and the CVS archive to check in patches and perhaps even release the packages. But I will not promise anything and I do know that I don't have much time for this. Therefore if we can't resolve those issues properly in the next 20 hours, you'll have to wait a bit longer for new packages. Andreas Footnotes: [1] He made the patch I've checked in. [2] I'm not using psgml. -- Andreas Jaeger SuSE Labs aj(a)suse.de private aj(a)arthur.rhein-neckar.de
