[Lxr-general] Install COBOL add-on to LXR

[Paolo P. <bod...@ho...>]

Hello all.

I recently installed  LXR cross-referencing engine version 0.3, and I 
integrate it with Bonsai.
Following the install instructions, I executed $LCRROOT/bin/genxref 
<mysourcedir>.
It creates cross reference files/indexes but just for "c" file.
I saw in sourceforge some other lang extension (such as java, shell, COBOL, 
shell ...)
Actually I need the COBOL extension.
Please anybody could tell me exactly what I should do.
1) What files I need ?
2) Where to find them ?
3) In particulary, how do I install and integrate it ?
4) There is some other nice extension for search and cross referincing for 
COBOL or CVS to integrate with Bonsai ? ( I already use glimpse!)

Thanks in advance,
paolo.

I haven't heard of anyone doing this - sounds like a good idea, and a 
possibly useful extension to LXR.

Might be, but I can't think of one off the top of my head.  If you could 
send me the SQL you were using I can look to see if it can be built into 
LXR in some way - perhaps by adding a "find unused symbols" search, or 
by showing unused symbols in the ident search?

Cheers,

Here is what I have done.  I am not sure exactly what version of LXR I
am running, here is the CVS Id from the ident script:
  # $Id: ident,v 1.6 1998/04/30 11:58:16 argggh Exp $

Here are some bits to add to Common.pm:
sub uiref {
    my ($desc, $pr, @args) = @_;
    return("<a href=\"unref".
           &urlargs(($pr ? "pr=$pr" : ""),
                    @args).
           "\"\>$desc</a>");
}

This goes at the end of titleexpand:
    } elsif ($who eq 'unref') {
        return($Conf->sourcerootname.' unreferenced identifier search');
    }

This goes after the 'find' part in modeexpand:
    if ($who eq 'unref') {
        push(@mlist, "<b><i>unreferenced identifier search</i></b>");
    } else {
        push(@mlist, &uiref("unreferenced identifier search", ""));
    }

This goes after the 'find' part in varlinks:
            } elsif ($who eq 'unref') {
                $vallink = &uiref($val, $identifier, "$var=$val");
            }

========================================================================
Here is my file called "unref".  It is just a modification of the ident
script, and it belongs in the same directory.

[Lxr-general] Finding unreferenced functions

[Michael O'C. <moc...@ya...>]

Hi,

Apologies if this has been asked before. I'm wondering if anyone's tried using
lxr on a codebase to find unreferenced / unused functions. I tried this on a C
/ C++ codebase I've been working in and found it very useful as part of a
clean-up exercise.

It depends on relational database storage of the lxr data (mysql in my case). A
query counting the number of instances of each symbol in the indexes table can
be compared with an equivalent query on the useages table, where the latter
count is <= the former the symbol can be considered unreferenced (i.e. not
used).

It's not foolproof, depends on indexing of all dependent code, and won't find
all instances (due to the regex nature of lxr's symbol finding / storage),
nonetheless I've found it an easy an quick way of finding unused code.

I guess there are better ways of achieving the same result, I'd like to hear
what people think.

Thanks,

Michael

I'm not hiding anything :-)  LXR can be configured to ignore certain 
directories - typically the CVS directories are hidden.

Sorry, that path doesn't mean anything to me (or I suspect anyone 
outside AOL).

Is this an internal installation of LXR setup by someone else?  If so, I 
suggest contacting them first, before asking the mailing list for help.

Cheers,

Malcolm

I wanted to view some code via LXR and give out some html links to  it, but

This is strange because I can update the module via CVS, so the code seems

Are you just hiding some code in LXR, or did the sysinfo code move or

I am trying to use LXR 0.9.3 whith swish-e and PostgreSQL - and I'm afraid

the Perl scripts (and in initdb-mysql) the table is called lxr_useage (with 
an extra "e")
2) when running genxref I encounter several errors:

Unfortunately the short answer is that there's no way to do this - the 
whole tree has to be re-indexed.

The slightly longer answer is that there were some patches/suggestions 
for how to make this work floating around (check out the lxr project 
page on SourceForge), but I don't think any of them were working.

If you do just re-run genxref, the result is that both the new & old 
positions of the identifiers will show up in the results.  What I've 
done previously was to let these errors accumulate during the week (when 
there wasn't time to fully re-index) and then do a complete clean 
re-index over the weekend.

If anyone wants to finish off the work on making incremental indexing 
work then I'd be glad to merge the patches.

Cheers,

Malcolm

[Lxr-general] genxref out of memory errors

[Neil B. <ne...@eh...>]

Hi,

I've been a long time user of LXR 0.3.  Recently we decided to give 0.9.x a 
crack since there were some nice new features we wanted to take advantage of.

Our CVS repository is rather large - occupying some 40GB of space and 8 years 
of development work.

The problem we are having is that genxref dies with an out of memory error 
after running for about a day.

The hardware isn't too shabby;

Compaq Proliant ML370 1GHz with 1GB of RAM.  After these errors I upped the 
amount of swap from 2 to 10GB and tried again.  Same result.  Last time I saw 
the output from top the process was eating 4GB of memory.

Can anyone suggest any reason why this would be taking this amount of RAM, or 
another way to generate the indexes so that it doesn't fall over?

I thought of indexing a top level directory at a time of the repository but 
then it wouldn't cross reference between the directories would it?

Thanks,

Neil.

Initial Comment:
Excuse me: 

I have some problem of my LXR (lxr-0.3.1). 

I followed the installation instructions from 
http://lxr.linux.no/New-INSTALL, 

install LXR at /var/www/html/lxr (/var/www/html is my 
Web Document root), 

add to httpd.conf: 

<Directory /var/www/html/lxr> 
Options All 
AllowOverride All 
</Directory> 

there is the content of /var/www/html/lxr: 

drwxr-xr-x    2 apache   apache       4096 Oct 20 01:38 
bin 
drwxr-xr-x    3 apache   apache       4096 Oct 20 07:54

dbdir: /var/www/html/lxr/source/ 

glimpsebin: 

map: /include/asm[^\/]*/ /include/asm-$a/ 
map: /arch/[^\/]+/ /arch/$a/ 
  

and restart httpd. 

at /var/www/html/lxr/source, 
executed: 
../bin/genxref preempt 

I use IE to connect 
http://hpcee.ntu.edu.tw/lxr/http/source, 

but some path maybe wrong,

for example, check.c links to lxr/source/check.c, but 
when I clicked it, there's no this file. 

but when I connect 
http://hpc.ee.ntu.edu.tw/lxr/http/source/check.c, 

it appeared right content. 

All of the links include "Cross Reference",  "test" and 
icons is wrong, etc. 

and I tried to fixed lxr.conf but still wrong. 

Could somebody help me to solve this problem? 
  

And how to write the lxr.conf if I want use multi-
sourceroot? 

I found a HOWTO doc at 
http://www.ibiblio.org/gleblanc/webtools-
howto/index.html#lxr, 

an example like this: 

sourceroot: gnome 
      /cvsroot/gnome/tree1 
sourceroot: othertree /cvsroot/gnome/othertree 

but my web page told me that my lxr.conf format was 
invalid. 
  

Thanks for your help!

[Lxr-general] installation problem

[adhiraaz <adh...@in...>]

Hi,


While installing lxr on  my machine I got following error massage after the genxref  :


"Can't locate DB_File.pm in @INC (@INC contains: lib/ /usr/lib/perl5/5.8.0/i386-linux-thread-multi /usr/lib/perl5/5.8.0 /usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.0 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl/5.8.0/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.0
/usr/lib/perl5/vendor_perl .) at /usr/share/lxr/bin/genxref line 31.
BEGIN failed--compilation aborted at /usr/share/lxr/bin/genxref line 31."


There really was not any file named DB_File.pm, what do I do now?


Thanks in advance,


Adhiraj

If the source code is showing up, then Apache isn't treating the file as 
a CGI script.  You can check /var/log/apache/error_log (or wherever your 
apache logs live) to see if it gives you any hints as to why.
My guess would be that your httpd.conf file isn't allowing the file to 
be executed.  You need to make sure  you have permission to execute 
scripts in that directory.  Also make sure that you have given the 
script execute permission to the user that Apache is running as e.g. you 
need a permission of rwxr-xr-x (755).

That's not surprising, since it needs some environment variables to know 
where to find the conf file.  But it does show that the script will 
execute (the error is generated by the script at runtime).

> Don't know what to do. Please help.

It would be helpful when asking for help to say what version of LXR & 
platform you're using etc.

Cheers,

Malcolm

[Lxr-general] Help, Can't get LXR to work

[Curran, D. <dc...@ti...>]

Hi

I'm having trouble getting LXR to work.

Firstly, I'm not trying it on the Linux Kernel, but on some of my own code.
However, I don't think that difference is the cause of the problem.

I have followed the install instructions from
http://lxr.linux.no/New-INSTALL.

My perl didn't have a DB_File module, but I installed it with CPAN.

I run genxref like this:
# cd /var/www/html/lxr/source
# /var/www/html/lxr/bin/genxref v-095

The genxref seems to run till completion.
It creates the files:
/var/www/html/lxr/source/fileidx     12288 bytes
/var/www/html/lxr/source/xref       749568 bytes


 - All files/dir inside /var/www/html/lxr have apache:apache permissions

 - I access the source as follows (it an intranet address):
 	http://madduck.mycomp.com/http/source/
   BUT I just get a standard directory listing like apache would normally
handle it.

 - I have placed a .htaccess file inside the /www/var/html/lxr/http

 - I added 'Cross Reference Stuff' to the only access.conf file I could find
on my system:
     /etc/security/access.conf

 - I have restarted apache.

 - I am using Redhat 8.0

 
What log files can I look at to see why its not working ?

Please help, I think that LXR for the kernel is an excellent resource, which
would really help me with my own code too.

Thank you for your time
dom

Summary: genxref fails on specific file - 'SimpleParse' error

Initial Comment:
When running genxref on a CVS repository I have, I get
the following error:
    Can't call method "getline" on an undefined value
at lib/LXR/SimpleParse.pm line 99.

The previous line states the file it was currently
referencing with a number that I have been unable to
determine the significance of that value.  When
starting genxref again, the same file is not flagged
with the error but another file is with a similar type
of error.  (I assume this file is skipped because its
determined that the file has already been referenced.)
 At times, I can see the previous file before the error
was the last file genxref stopped at.

I have installed LXR 0.9.2 and swish-e 2.2.3 and mySQL
is being used as the database.  I am approaching about
10 times where the genxref has errored and the swish
index files have not been created.

[Lxr-general] search utility not working

[Rick T. <te...@fn...>]

Hi
    I've run into a problem with the search utility for the CDF code
browser.  I tried a freetext search on the string "decayBMeson"
and ended up with no results.  However, I find in the EvtGen
package (EvtGen/src/EvtGenInterface.cc, line 33) the following
line of code.

031 /* Constructor */
032 EvtGenInterface::EvtGenInterface(EvtGen *generator, bool adjustCPAsymm,
033  bool verbose, bool decayBMeson, bool decayBBaryon, bool decayPromptCharm){
034   _generator = generator;

It seems to me that the search utility is not really working.  Would
you please look into this problem?

                            Rick
