Re: mkisofs multi-extent: more bugs

[Andy Polyakov]

 Interesting that you seem to have time to write this

This as communicate with growisofs user [and spend 7% of my post to 
point out misleading statement about cdrecord]? Well, how I dispose my 
time is my business, but if you have to know it's more important to me 
to communicate with dvd+rw-tools users. In other words yes, if I have 
few minutes I'd rather do that.


 but to not like to support
 mkisofs.

I don't understand... You have time ... to not like support mkisofs? 
Like have time to dislike doing something [without actually doing it]? 
No, I don't have time for such things either and don't do that. Or was 
it *do* not like [*to*] support mkisofs? Is it my job to support it? I 
spend several hours on bug hunting and this is thanks? Well, thanks for 
encouraging words!


 If you really have problems with mkisofs,

In a spirit of personal remarks I personally don't really have problems 
with mkisofs. I personally use home-patched version at my own 
discretion and don't really have problem with this.


 please make reports in a way that
 allows to fix them.

As I already said I'm *sorry* I can't do better, primarily because of 
lack of time. I'm ready to answer specific questions [but not about form 
of my report], if they don't take very much time [minus time I've spent 
reflecting over the remark and writing this], but I don't have time to 
reformulate my report[s]. A.

 http://lists.debian.org/cdwrite/2008/07/msg00082.html 6 (six) a=40 
 multi.c bugs were reported:

 #1. end-less loop [or premature exit from it] in read_merging_directory;
 #2. incorrect merge of extents from previous session [generated by 
 alternative iso9660 formatter];
 #3. files or extents are omitted from multi-session recording due to 
 incorrect value returned by read_merging_directory;
 #4. failure to sort merged directory because of insufficient clean-up in 
 check_prev_session;
 #5. failure to sort merged directory if multi-extent files share same 
 iso9660 name;
 #6. apparent memory leak in check_prev_session;

 Of these 6 bugs two were fixed, #1 and #4, and one, #3, kind of fixed. 

If you found real problems, it would help a lot if we could discuss things in a 
way that allows us to forward.

The problem with your reports is that you mix several problems into one report
and that you only partially describe the problems in a way that allows to 
repeat 
them. You also send cumulated patches that include changes that itself introduce
bugs. This is why I could only fix about three problems from the list you send
half a year ago.

I am going to fix all problems that can be verified, but I am not going to
apply patches if I see a single problem in a provided patch. I am adopting 
patches only if they do not introduce obvious new problems and in case that some
basic tests pass with the new code.

As ISO-9660 allows to introduce many dirty tricks, many of them are unsupported
by mkisofs, so please reorder your list to let #2 appear last.

For the reasons mentioned above, I propose that you present each item in your 
list separately together with a description that allows to repeat the problem. 
If you have a fix that is specific to this problem, you are of course welcome to
present your fix.
