Hello,
I have this tool that shows me Git log (screenshot attached). I've
added a commit whose message apparently triggers cores. Luckily I have
-g, no -O2, near-HEAD (ccc0b6f) zsh running with ulimit -c unlimited.
Making things visual, the collection of cores is:
core.54623 core.80705 core.89143 core.89731 core.90081
easily to extend. The back traces are the same in 4 tested back traces:
(lldb) target create "/usr/local/bin/zsh-5.2-dev-2" --core "/cores/core.90081"
warning: (x86_64) /cores/core.90081 load command 134 LC_SEGMENT_64 has
a fileoff + filesize (0x28b73000) that extends beyond the end of the

First frame points to pattern.c:651. It is "next = PATNEXT(pscan);"
(my exact HEAD is: ccc0b6f). I did:

(lldb) p pscan
(Upat) $1 = 0x0000ff9324b59968

Not sure what to do next. Two complete back traces are attached.

PS. Last runshfunc() uses this file:
https://github.com/psprint/zcommodore/blob/master/__zcmdr-process-buffer
I've added debug marks to this file – attached is diff where I've
added them. The resulted debug-prints file contains also the text
processed, with the ^A, ^B, etc. – this is what patcompile() is feed
with. Mark 8 is the last one generated before core, and points to this
lines as the source of core-triggering patcompile():
# Remove the word
MATCH=""
buf="${buf#(#m)$word}"
Best regards,
Sebastian Gniazdowski

OK – here's minimal test case. It contains error in first filename,
but the core was triggered anyway, in each run of two that I've done.
Two files, input1.txt, input2.txt, with the problematic strings, then:

I have extended_glob set in zshenv. It is needed. However it seems
that the additional ABSD setting (huh I did fork in .zshenv, turns
out) helps to make the core more often. With only extended_glob ~15
runs are needed. I attach complete test.zsh.

My new observations:
– ^A, ^B, ^F, ^Y don't have meaning: replacing them with A, B, F, Y
doesn't stop core dump
– the "ndash", .i.e. this char: >>> – <<<, has a role, because
replacing it with other char, also one like §, stops core dump
– length of the string has a role, tired shortening the string on the
left and no core dump then
I attach input2b.txt with no control chars and test2.zsh (zsh -f) that
opens that file

Your stack trace in the first message on this thread has a string as the
"exp" argument of patcompile() that makes me suspicious. The comments say
that this argument is expected to be metafied (pattern.c 522), but as best
I can tell it's passed down from paramsubst() tokenized but not metafied.
(I don't have access to my usual debugging platform this week.) One of the
multibyte characters in the string

... in that exp argument, the character in the position where you
identified ndash in input2b.txt, has a byte with hex value 0x83 which would
cause it to be incorrectly interpreted as a metacharacter. If this is the
case, this probably results in the pattern being mishandled.
There were some changes made a while ago to try to optimize memory
(re)allocation during pattern compilation and globbing. It's quite
possible that miscounting of the number of characters in the pattern is
causing problems with the allocated buffer. At this point though, I'm just
speculating.

Pardon me if this has been discussed before, but why don't we introduce
the type definitions
.
struct metafied_t { char *v; };
struct unmetafied_t { char *v; };
.
and start incrementally replacing uses of "char *" with uses of these
types? This will gain type checking for metafied v. unmetafied strings,
as these two types do not implicitly convert into each other (attempts
to do so generate a compiler warning).
Cheers,
Daniel

That comes from "s" within paramsubst(), which is just the minimally
modified parameter substitution string from the command line, which
should still be both metafied and containing tokens (the ability to
quote characters that look like tokens being the main use of
metafication). It's not the value of the parameter, which goes a
different way. The pattern just gets compiled once.
Here's an xxd of the complete expression from the backtrace --- the
exp=" and the final double quote before the newline are therefore not
part of the string (this is also a bit confusing since I've left in the
\x.. escapes put in by the debugger but they aren't immediately
relevant):

The dodgy sequence is around "e2 80 83 ef bf bd" from byte 0xa4. That
83 is indeed a Meta, and it looks like it's the only one in the input.
Unmetafiying the following ef gives cf, which is not in the range that
would have caused it to be metafied.
So it looks like this did indeed get previously unmetafied when it
shouldn't. The question is where... If this is the case, the crash
could be to do with the lack of null determination rather than
misinterpretation of characters.
The text in that pattern has come from the $word in Sebastian's script:
buf="${buf#(#m)$word}"
Note that (barring accidents with /etc/zshenv) GLOB_SUBST is not on, so
$word should be substituted literally. This came from:
word="$(<input2b.txt)"
which contains evidently valid multibyte characters (they're fine in the
output I'm seeing but I don't dare mail them raw). xxd gives

Here we have "e2 80 93" where we previously had "e2 80 83 ef bf bd". The
93 becomes B3 on metafication, which should give "e2 80 83 B3", which
isn't what we've got.
The function readoutput() that inputs the word does do metafication.
That's no great surprise as part of the mayhem is evidently due to the
fact it has been metafied at some point. I've confirmed by stepping
through this gives 83 b3 [except gdb helpfully says \203\263, but that's
what you get with old technology].
However, when I hit getmatch() I've still got what I expect, the
correctly metafied input string with \203\263:
$11 = 0xb78a8d70 "\210\204m\212\001glogB\001\060\001/Diff/\001/Users/sgniazdowski/github/zsh-navigation-tools.git\001\060a87c8044c1c6677a38ccdabd36334cc2aaab496\002\006\"znt-tmux.zsh \263 initial commit of skylite21 submission\"\031"
So some option / variant behaviour / extraneous memory effect is coming
into this.

This probably is a good idea, although the intermediate state where this
has been only partly done is likely to be a bit of a mess. Modern
compilers should be able to keep this working efficiently.
Some thought could be given as to whether the unmetafied structure should
contain the length, too. The only uses of unmetafied strings I can
think of that wouldn't need it are at the library / system interface,
which requires unmetafied null-terminated strings.

I'd expect to encounter a lot of problems with (char **) arrays where
every element of the array is (or not) metafied. (Hopefully there
aren't any that are mixed). As was noted in the discussion of passing
around lengths of arrays when manipulating array parameters, the older
code makes a lot of assumptions about pointer arithmetic and s[1][1]
subscripting and so on.

A 'char **' would become a 'struct metafied_t *', i.e., an array of
structs. This is not equivalent: the array stride of the latter may be
larger than the array stride of the former.¹ However, this would only
be a problem if the code makes assumptions about where elements are
allocated relative to each other, e.g., if the code assumes that
«ary[1] - ary[0] == 1+strlen(ary[0])» or otherwise uses the values of
ary[N] and ary[M] in a single expression.
Does the code make such assumptions?
Cheers,
Daniel
¹ The array stride is sizeof() of the array element's type. The
sizeof() of the struct type may be larger than sizeof() of its member
because structs are allowed to contain padding after the last element.

No, char ** is used fairly generically.
I don't think arrays of unmetafied strings are that common, and in at
least one case (the print builtin) having the length as part of the
unmetafied_t structure, avoiding a parallel length structure, is
beneficial.

I am more concerned about the large number of places where s[0][1]
would have to become s[0].v[1] than about whether the strings are
metafied or not. Similarly *s++ and so on.
Including the even larger number of places where we'd have to convert
e.g. "if (!s)" to "if (!s.v)" because it's not possible to pass a
null struct by value.

Ack. I saw you say this in your previous mail; I didn't respond since
I don't have an opinion one way or the other as to how often the length
would be needed.

Starting out with a simple typedef would at least add documentation and
allow an incremental approach. Would still need to add .v everywhere en
masse when going to a struct, though.
I did some work on a code base that had a convention of uint8_t*
for UTF-8. Seemed to work well as far as I could tell.
For the history file we should perhaps consider not using locale
dependent metafied strings. UTF-8 with an overlong encoding for a null
perhaps? grep etc might still not like the overlong null but they should
be rarer.

Even with char**, that condition is only likely if the array was
created with a literal assignment. And it is easy to test for
problems by forcing the size of the struct and running the test
cases.

Does anyone have a way to get type checking that doesn't involve
adding .v everywhere? The solution doesn't _have_ to be portable; we
can use compiler-specific magic of gcc or clang, for example, so long as
some developers use that compiler routinely.
If we do the typedefs first, then adding .v later should be easy with
something like coccinelle's patching tool. (It allows doing
search/replace in terms of the C syntax tree.)

+1 to making the history file locale-agnostic.

I was thinking of code that allocates multiple elements in a single
malloc() chunk:
char **array, *storage;
for (i = 0; i < LENGTH_OF_LIST; i++)
sum_of_lengths += strlen(list[i]) + 1;
storage = malloc(sum_of_lengths);
for (i = 0; i < LENGTH_OF_LIST; i++) {
array[i] = strcpy(storage, list[i]);
storage += strlen(array[i]) + 1;
}

Wouldn't it suffice to use
typedef char *unmeta_t;
typedef unsigned char *meta_t;
(or the reverse if we believe we're mostly going to be working on
meta_t). If we do that and also enable the GCC warnings -Wtype-limits
-Wconversion -Wformat-signedness would we not get adequate verbosity
without changing pointer arithmetic and dereferencing?
I hadn't even considered all the places where using a struct would
change memory allocation strategy. Oof.

Maybe my inexperienced point of view will help? Typical pscan, next values are:
====== BEGIN ====== exp: zplugin�saved�visual�line�mode
pscan: 0x7fd9b425d820, next: 0xffffffe700000000
AFTER pscan: 0x7fd9b425d820, next: 0x7fd9b425d850
pscan: 0x7fd9b425d850, next: 0x7fd9b425d850
AFTER pscan: 0x7fd9b425d850, next: 0x0
When core is triggered, this looks like:

Cannot print last "next" from debugger, inaccessible memory. What can
be seen here? First next value seems to be weird in both cases. Either
0xffffff at the beginning, or low value 0x10886db73 (low when compared
to pscan's value). Then, AFTER message shows the weird value is fixed.
First log says there should be 0x0 after successful processing. In
second log it is seen that instead of 0x0 another weird value is
assigned to "next" – it starts with 0xff. I did many runs and it was
always that the odd value appeared before core.
I also did step by step walk through patcompile(). Unluckily it wasn't
a core-triggering dump (next ended with 0x0). I attach screenshots
with some crucial places.
dbg_metacharinc_detecting_meta.gif

Traversing the string METACHARINC() is called. It rather correctly
detects special characters and skips them, as shown.

Almost ceratinly you need to hit misbehaviour (or be about to hit
misbehaviour :-() before we're going to get anywhere. It's not
fundamentally broken in normal cases.
If you can provoke it frequently enough, valgrind is the most likely
thing to help. In your case, you might think a few runs under valgrind
should produce some interesting out.
I tried turning on the additional valgrind integration for heaps, but
that was doing weird things, in fact rather dishearteningly two sits of
different weird things on two different machines (one rather out of
date).

Subject: valgrind of patcompile() errors
To: zsh-workers@zsh.org
I do not get these errors on a second machine architecture I tried. The
difference seems to be that the error happens on the 64bit architecture
but not on 32bit.
This one line may be telling:
==26676== by 0x49F539: patcompile (pattern.c:672)
That is inside a block where a metafied string is converted back to an
unmetafied one to do a literal match.

Thanks, I think we're getting somewhere. Yes, I think the actual
problem is in the block where you've been adding the debugging.
It's the same one Bart noted when he managed to get this to show up with
the line numbers.
I think this:
if (nmeta) {
char *oldpatout = patout;
patadd(NULL, 0, nmeta, 0);
/*
* Yuk.
*/
p = (Patprog)patout;
opnd = patout + (opnd - oldpatout);
dst = patout + startoff;
}
can have an effect on where pscan should be pointing because of the
reallocation. A better way of doing this would be loop first to count
the space needed then allocate it.
See if this helps (I think next is the key one to update):

Still segfaults in the same place, and Valgrind reports two 8-byte reads.

Hmm... well, what I've posted fixes the pointers at line 650 of
pattern.c
for (; pscan; pscan = next) {
next = PATNEXT(pscan);
where they would have been wrong before, so if you're *still* seeing
problems after the change, you've found something else.

Valgrind points at patadd(NULL, 0, nmeta, 0). Wonder why not to its
interior? But to all logic, problem should be inside patadd() because
nothing else near dereferences a pointer. So there might be two
problems. Debugger didn't report inaccessible memory when I did
step-over on the patadd(), maybe memory is accessible but invalid from
other reason recognized by Valgrind.

Just to be sure, could you confirm the problem goes away if you change
line 292 of pattern.c
/* Default size for pattern buffer */
#define P_DEF_ALLOC 256
to
/* Default size for pattern buffer */
#define P_DEF_ALLOC 512
? That's not a fix, it's just putting off the problem, but if it's
initially allocating something larger than what your pattern needs I'd
expect the crash not to happen.

I'm now starting to wonder if the realloc is a red herring and the key
point is this...
* Careful in case we've overwritten the node for the next ptr.
It's a long time since I did this but if the P_PURESTR flag is set,
I don't think there can be more than one P_EXACTLY. So the solution may
be to break out of the for loop at the end of the
if (P_OP(pscan) == P_EXACTLY) {
/* .... */
break; /* <- here... */
}
immediately after line 692 in the modified code since the "next" can't
be relevant any more.

Tested the change, no segfault, also when break is added to unmodified
code. Also checked if the pattern still matches (made use of the
prepared input1.txt, input2.txt) and it does, in both versions.

Thanks.
I think that *is* the correct fix --- we add PAT_PURES to the flag that
will later be used when we run the pattern, and in that case any of the
usual wordcode infrastructure is irrelevant because we do indeed treat
it just as a single (metafied :-() string. So breaking out of the loop
immediately is the right thing to do.
