Re: "strings core"
You do know you can "fix" that by making all error message strings be in read only memory, which won't be in the core file.

Re: "strings core"
On some cases like memory leak, - and only in that case
strings core | tail -10000 | head -1000
- -10000 and -1000 are not deterministic values-
can sometimes help to identify a pattern.
It can gives sometimes tracks to explore, even if in any case it will not give directly the answer.

Re: "strings core"
even if a user is knowledgeable enough to make sense of the stuff they get out of "strings core", they are very likely to be good enough with a debugger anyway.
a debugger would provide enough tools to see exactly what (and where) one is looking for.
as for shifting error messages into read-only text, that has to be done in all runtime components. but even when that is done, i still don't see how "strings core" could be better than a debugger given the potential wild-goose-chases.
no use making the user print strings, confuse themselves and open the problem up to a hundred interpretations by everyone who wants to help.
i started a new thread to avoid having to repeat this in every other thread. now i (or you) just have to link this one into all those threads :)

Exactly.

There are several reasons:
1) There will be a performance benefit.
2) If the error strings aren't there, nobody will suggest using strings(1).
3) If a string does show up, it may actually be important.
>no use making the user print strings, confuse themselves and open the problem up to a hundred interpretations by everyone who wants to help.
Right.

Re: "strings core"
So in any case there is no need to ask for a strings core if you are trying a remote debug.
You gain time when you ask for corefiles, libs, and executables.
strings core is just a trick which may be used, but not as a first approach in any case.

Re: "strings core"
Please indicate which topic made you write this topic.
I tried to find with a simple google: +site:itrc.hp.com "strings core"
It found many hits, including this, but nothhing otherwise recent.
Google did report something intersting, which I had not really noticed before.
It suggested:
"IT Resource Center forums - core files - This thread has been closed 10 posts - 8 authors - Last post: Mar 16, 2007
:
forums11.itrc.hp.com/service/forums/questionanswer.do?threadId=1107726 "
Does that "10-posts 8 authors - last post" not suggest that Google 'understands' itrc topics?
The 'source' for the page in question does have:
<meta name="replyauthors" content="Sunny Jaisinghani, Adisuria Wangsadinata, Reshma Malusare, Eric Jacklin, Matti Kurkela, Dennis Handly, Johnny Damtoft, prash" />
That could explain the '8 authors', but it does not have an (obvious) reply count of last reply date (GMT vs US?)
Just curious.... and not on topic. Sorry.
Hein.

Re: "strings core"
there's no question on why error messages should be moved to read-only text.
hein,
this is not about one particular thread but the ITRC search shows up these recent ones.
http://forums11.itrc.hp.com/service/forums/questionanswer.do?threadId=1272520

and the stuff that you posted about google search results is interesting. it seems that only some threads have this information, though.
