strace traces system calls, the border between userland programs and
the kernel. You can strace the whole apache processes from startup
(strace -f -ff -F -s 200 -o xxxxxxx /etc/init.d/apache start) or
attach to individual worker backends afterwards (-p PID).

Apache is one of the harder programs to properly strace, because it
does so much surrounding work, which all results in a lot of issued
system calls, bloating the logs. It's kind of an art to read those,
guessing what happens here and there :)  However, you won't really
notice suspicious stuff unless you're used to C programming.

Sorry, don't know much about strace. Didn't know it could be useful in 
debugging my problem. Also, saw no errors in apache logs since I think 
the "sources" script detected the error and generated OK html which just 
said file not found. No permission denied or such messages.
Actually, didn't take 2 weeks to fix, just didn't reply immediately.

Possibly you will say rtfm, but how do you use strace to debug lxr 
problems (if I dare ask).

I created a user/group "test" and within test account I was unable to 
cat files or list files in /home/me/lxr-file (set to 755) unless I 
changed /home/me to 705 so permission seemed to be inherited for this 
simple case (unless I am missing something here).

By the way, thanks for your excellent work on LXR. I use it constantly!

I hope you didn't need full two weeks to look at either strace output?
Were there no error messages in apache's error.log? No specific error
messages in HTTP output?

To answer my own post, the reason was because the files accessed by lxr 
were in my home directory with permission 700 and apache could not go 
there. Pretty simple actually but not much hint from apache or lxr as to 
what the problem was. Just was looking at the /home/me/lxr-file/ 
directory which was set to 755, I think, but was was overriden by the 
/home/me/ setting of 700. (Didn't realize the permission are inherited 
but I guess they are.)

[Lxr-general] apache (httpd) on f8 vs. fc6 running LXR

[Gene S. <gd...@ch...>]

I have a LXR setup on fc6 that works fine. When I moved it to f8 (which 
seems to have the same versions of httpd, perl, mysql etc) I can only 
get it to work if I change the user/group in httpd.conf from 
apache:apache to myusername:myusername.  The files accessed by httpd, 
perl etc are world readable and executable but owned by root, as they 
were in fc6. These are in /usr/lib/perl5/site_perl/....

I have tried changing all the files to owner/group apache:apache but 
that does not help. I have disabled selinux and that makes no 
difference, but saw no errors before disabling. I have made httpd.conf 
user/group nobody:nobody and that does not work. Only when I use my own 
UID/GID in httpd.conf does LXR work.

I have set-up LXR several times before with other fedora/rh versions 
with no problem this difficult. Why would the apache account not work in 
f8 but it did work with the same files in fc6? Or should I just run 
apache as myself and be happy. This is only really used from localhost 
for the most part, not on the internet.

By "not work" what I mean is all I see when I go to a link in LXR is
"The directory / does not exist." which is produced in the 
/usr/local/lxr/sources script. No errors appear in the httpd logs since 
the script is producing a valid page.

Got no answer on Fedora list when I asked this. Hope this makes it 
through the spam.

[Lxr-general] query about lxr

[ashitosh w. <a.d...@gm...>]

Respected sir,

 I complete Installations of  Lxr with apache server and  glimpse.

 When I use URL : http://10.52.64.100:8080

                     it shows it works.But when I tried to access the code

     URL:http://10.52.64.100:8080/kernel/source it gives error  "You don't
have permission to access /kernel/source on this server"

I added

ScriptAlias /home/kernel "/home/lxr/http"

<Directory "/home/lxr/http">
    AllowOverride None
    Options None
    Order allow,deny
    Allow from all
</Directory>


in  httpd.conf  .


Can anybody please tell me what is the problem ?

 Thanks in advance.


Thanks  & Regards

Use CVS, the "Concurrent Versioning SystEM" (or "Crappiest Version
System ever made" for what it's worth...)

You once need to log on:

$  cvs -d:pserver:ano...@lx...:/cvsroot/lxr login=20

(Just press the Enter key when asked for a password.)

Now you can proceed downloading the sources:

$ cvs -z9 -d:pserver:ano...@lx...:/cvsroot/lxr co -P l=
xr

As further development taked place, you may want to update your
checked-out sources (from the above step) to whatever it up-to-date
right now:

$ cd lxr/
$ cvs update -d -P

That's all :)

Additionally, keep in mind that files beginning with a dot are
"hidden" files.  For `ls', you need to add the "-a" switch to the

lxr.sf.net points to a "new site" -> http://sourceforge.net/projects/lxr
There is a menu item "Code" with an item CVS in it which leeds to

[Lxr-general] Finding strings with LXR

[Steven G. <Ste...@ce...>]

Dear Help,

I would like to do a "general search" with LXR to find all of the  
"MSG::ERROR" statements under MuonSpectrometer.  If I enter  
"MuonSpectrometer" in the "Files named:" window, I get a listing of  
all of the MuonSpectrometer software.  If I enter "MSG::ERROR" in the  
"Containing:" window, I get a listing of the first 1000 files  
containing "MSG::ERROR", but this does not even get close to  
"MuonSpectrometer" in the alphabet.  If I enter both, I come up empty!

I suspect that only the first 1000 files are searched for the string,  
as I know that I have plenty of "MSG:ERROR" statements in the  
MuonSpectrometer software.  Does anyone know how to change that  
behavior?  I would like to avoid renaming my package to  
AAMuonSpectrometer!  Thanks.

Best Regards,
Steve

Mr Jan-Benedict Glaw

Its so sweet of you to look at all the configuration. Its always a
pleasure to know people like you are out there to help such newbies
like me.

I will work on your hints and let you know about the conclusions. I

Either the spam filter ate it, or it simply didn't find its way to the
mailing list.

Please resend--this version was missing the mentioned attachments.

You can use any existing user, but in general, it's wise to separate
stuff that's, well, separate. So better create a fresh user for LXR.

> > Does mysql server have local users?

It does. Usually, all the SQL servers have their own user management
that's not at all related to system users.

> > Is lxr linux user of sqlserver user?

I don't understand this question.

At most, I see these users being in the game:

  * One (system) user that Apache is using. This usually is "www",
    "apache", "www-data" or something like that, rarely "root" is
    uses.
  * One (system) user that's owning the LXR related files. The Apache
    web server's user (www, apache, www-data, ... as above) must have
    read access to the LXR files. Using the same user is the simple
    approach, but depending on your setup, you may want some real user
    to be able to update LXR or change its configuration, so it may be
    a regular user accoung.
  * A (system) user that the database server is using, usually named
    like the RDBMS system (eg. "postgres", "oracle", ...)  You
    possibly need to have access to this user to create the next one,
    a DB-specific user for use with LXR.
  * A (DB-specific) LXR user, which lifes entirely inside the DB,
    including its password, access management etc. Account data for
    this user is usually placed into the lxr.conf file.

> > My database is empty even after generating the indexes

That means that either there was nothing to index, or that some error
happened. Tough you didn't post error messages (and the config
attachments aren't in this resent email), we this is a guess--at best.

> > I do not use CVS so should I comment out its requirements? Like CVS bin

LXR is a system to present source code with the help of a web browser.
You need to give LXR the source code you want to present. How did you
do that? (Your lxr.conf file would probably tell us...)

There are several ways:

  * Offer a Bitkeeper repository to LXR.
  * Offer a CVS repository to LXR.
  * Offer a GIT repository to LXR.
  * Offer plain files to LXR (eg. extract tarballs of the project:
	mkdir /data/sources/linux-0.01 &&  ( cd /data/sources/linux-0.01  && tar x=
jf /path/to/linux-0.01.tar.bz2  )
	mkdir /data/sources/linux-1.0.0 && ( cd /data/sources/linux-1.0.0 && tar x=
jf /path/to/linux-1.0.0.tar.bz2 )
	mkdir /data/sources/linux-2.0.0 && ( cd /data/sources/linux-2.0.0 && tar x=
jf /path/to/linux-2.0.0.tar.bz2 )
	mkdir /data/sources/linux-2.6.1 && ( cd /data/sources/linux-2.6.1 && tar x=
jf /path/to/linux-2.6.1.tar.bz2 )
    )

Without sources, nothing will be indexed, because there's nothing to
index.

> > I have no idea how to install the test units! What to do?

Ignore it.  It's mostly used to test LXR after hacking it.

Apache2? Apache1? httpd.conf?  Thses handler options have to be set
for the <Location>:

    SetHandler perl-script
    PerlHandler Apache::Registry
    Options +ExecCGI

ISTR that this should be fixed in the CVS version of LXR.

Thought about offering somebody login data to the machine to install
it together with you in a screen -x session?

Eh? No access to no machine?

Won't work that easily. In theory, a script could be written to fetch
all and any content off a LXR server, but after all, LXR is a
server-based technology.  So there's no "easy" way to simply "dump"
all pages for offline use, but it has been considered (for speed
reasons) to locally cache requested pages.

> Did any body try to use lxr locally in his machine?=20

You can install it locally, but this needs a local source repository,
a database and a web server...

I'm sorry, but there's no easy way in doing that, except installing
it.

This is an important step.  What exact LXR version do you use
(released 0.9.x or from CVS?) and what exact kind of web server
(Apache 1.x? Apache 2.x?) are you using?

>From the INSTALL file:
Apache2, modperl2 and LXR

|Edit the .htaccess file and change "Apache::Registry" to
|"ModPerl::Registry".  You also need to let modperl2 know about

|		"/usr/local/lxr/lib/Files");
|1;
|- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
\---------------

For me, it worked by just installing the appropriate Debian packages
(libapache2-mod-perl2 and apache2) and enabling the module (link it
into /etc/apache2/mods-enabled from mods-availabl).

[Lxr-general] lxr for local use

[Swarup S. <me...@ya...>]

Hi All,
I don't have access to a machine for which I don't have admin privileges. I want to use lxr in that machine. 

Is it possible to configure lxr so that I can browse the source code in my PC locally, without suing any httpd, Apache?

Did any body try to use lxr locally in his machine? 

It would be great if i get some suggestions to do this locally in my machine.
