Re: [Lxr-general] Wildcards in general search

[Dr R. <drr...@gm...>]

Hi and thanks for your reply Adrian,

I have read that Swish-e documentation and there's this limitation:
"The wildcard * may only be used at the end of a word."

Using * in the middle of word/before word outputs error:
Search failed: internal error
err: Wildcard not allowed within a word

? works in the middle of word, but it can replace only one character..

I'll have to find out
1. if there are some tricks to get * wildcard work in the middle of
word using e.g. MySQL/perl search formats or scripts.
2. or I'll just study whether the Glimpse supports other than trailing
wildcards and switch engine from Swish-e to Glimpse.

Re: [Lxr-general] Wildcards in general search

[Adrian I. <adr...@ho...>]

Hi Heikki,

In the general search I believe the search term is given straight to  
the underlying indexer, which in your case is Swish-e. Hence, the best  
place to look for documentation on searching is their website (http://swish-e.org/docs/swish-search.html 
).

It suggests that * would solve your problem as that matches zero or  
more characters. Their example shows it in quotes so that might also  
be needed.

Hope that helps,
Adrian

[Lxr-general] Wildcards in general search

[Dr R. <drr...@gm...>]

Hi,

Is there any other wildcards than '?', that can be used in the middle
of word when I am using general search? Or is there any way to
implement such a feature to Lxr? E.g. I need to find every word that
begins with "Please" and ends to "Me" => Please*Me could find words
PleaseHelpMe and PleaseYearghMe.

There were already one mail about this, but it was related to
identifier search and I was not able to use dot (.) as a wildcard. [
[Lxr-general] wildcard identifier search ]

I am using Lxr-0.9.6 and Swish-e-2.4.7.

What I really meant to say was:

./genxref --url=http://localhost/lxr/source/metis
./genxref --url=http://localhost/lxr/source/geant


However, that was probably obvious.  Back to the issue at hand though...

Thinking the problem over further this morning though, I think I've
answered my own question about how to use a multiple configuration block
section in lxr.conf.

I'm guessing I should create the directory path

/var/www/localhost/htdocs/lxr

Then under this directory create something like a master directory

/var/www/localhost/htdocs/lxr/master

I should move lxr.conf, .htaccess, and all of the html template files to
this directory.  Then, for every source tree I want to index, I just
create a different symbolic link to this master directory for the
webserver to access.

/var/www/localhost/htdocs/lxr/geant->/var/www/localhost/htdocs/lxr/master

/var/www/localhost/htdocs/lxr/metis->/var/www/localhost/htdocs/lxr/master

etc.

I'll be working with the same html template files, .htaccess file and
the lxr.conf file across all directories.  However, when accessing the
directories through the webserver, I'll be coming in through different
URLs, and the different blocks in lxr.conf will be activated.

So I'd index this setup with:

./genxref --url=http://localhost/lxr/geant/source
./genxref --url=http://localhost/lxr/metis/source

... and access with:

http://localhost/lxr/geant/source
http://localhost/lxr/metis/source


Was this the intended setup for a multi-block lxr.conf setup? Or is
there a way that avoids all of the symlink directories and works
directly through the various source, diff, find, ident, etc. scripts.

Thanks,

[Lxr-general] Multiple configurations question

[Robert D. P. <ROB...@sa...>]

Hi,

I've installed lxr-0.9.6 on a Gentoo system and have some configuration
issues that I'm hoping someone familiar with lxr can quickly answer.

I can set up lxr to cross reference a single source directory tree and
it works like a charm.  What I'd like to do though is have lxr
cross-reference multiple separate source trees and present this through
different urls.  I'm looking for recommendations on the right way to do
this.  

Clearly, lxr.conf can hold multiple configuration sections that are
matched against the 'baseurl' or 'baseurl_aliases' for each section.
However, I can't quite work out the correct variable values to get the
multiple configuration setup to work.

I currently have lxr installed under /var/www/localhost/htdocs/lxr

My lxr.conf for indexing a single source tree (only one version)
in /usr/local/src/metis-4.0 is set up as:

{
'baseurl'  => 'http://localhost/lxr'
'virtroot' => '/lxr',

'variables' => {
	'v' => {
		'name'  => 'Version',
		'range' => [sq(metis-4.0)],
		'default' => 'metis-4.0'
		},
....

'sourceroot' => '/usr/local/src',

}

... and this all works fine.  (Probably I should have sourceroot
=> /usr/local/src/metis-4.0 and the version => '', but that's probably
not relevant to this.)

I can ./genxref --url=http://localhost/lxr to generate the cross
references then browse to http://localhost/lxr/source to view the
directories and cross-referenced files.

What I'd like to be able to do is access different source trees through
different urls.  Something like:

http://localhost/lxr/source/metis
http://localhost/lxr/source/geant

Is this possible?

I obviously could just duplicate the script directories.... create
something like:

/var/www/localhost/htdocs/lxr/metis
/var/www/localhost/htdocs/lxr/geant

and "cp -r" the various  scripts like source, find, genxref,ident,
search and *.html to the duplicate directories.  Or, I could even just
symlink them.  Or, for that matter, I could symlink the various source
tree directories together under one root directory and index this.
However, the fact that lxr.conf handles multiple configuration sections
makes me think there should be a more elegant way to set this up.

I can

./genxref --url=http://localhost/lxr/source/metis
./genxref --url=/var/www/localhost/lxr/source/geant

and generate the appropriate indexes.  However, when I try to access

http://localhost/lxr/source/metis

the path to the file or directory being looked for typically has a
spurious extra "metis" or "geant" in it.  

Is there some trick I'm missing?

What would be fabulous is a sample lxr.conf with multiple configurations
in it and the corresponding cgi script directory layout to match.

Thanks,

Hi,

Every problem we experienced were caused because lack of access
rights. Last problem was caused because search (general search) was
unable to open index files from /home/admin/swish-e. Index files can
be accessed from folder under root (e.g. /some_folder).

Thank you for your help and quick replies Malcolm.

Re: [Lxr-general] Problem installing: "The directory / does not exist"

[Dr R. <drr...@gm...>]

Hi,

At the moment this root is just fine place to keep our sources, so
I'll leave that fighting with Apache later.

- Did genxref generate swish-e index files in $swishdir?

Yes. Folder /home/admin/swish-e contains following files:
-rw-r--r-- 1 root root       0 Nov  3 12:54 testFolder.filenames
-rw-r--r-- 1 root root       4 Nov  3 12:54 testFolder.index.prop.temp
-rw-r--r-- 1 root root  802160 Nov  3 12:54 testFolder.index.temp

I just created new index from new folder and I got only
myFileName.filenames file. Point is that indexing seems to do
something, and I get at least .filenames file.

- Using swish-e from the command line, can you search using the indexes created?

Looks like command line search is trying to use wrong index file,
because I get error:
"err: Index file error: Could not open the index file 'index.swish-e':
No such file or directory"
I can not find any parameters that could be used to search using my
own testFolder.* -indexes. I have set variable:
swishdir=/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/home/admin/bin:/home/admin/swish-e,
like described in installation instructions.

- Can the user that apache is running as access those indexes?

I don't have answer for this yet. Might be the problem as well, and I
am investigating this.

That would suggest that /home/admin/indexed-src was not readable by
the user that apache is running as.

A simple test of this is to configure /home/admin/indexed-src as a
normal Apache document directory and see if it can be read.

Possibly the same problem?
Things to check:

- Did genxref generate swish-e index files in $swishdir?
- Using swish-e from the command line, can you search using the indexes created?
- Can the user that apache is running as access those indexes?

Re: [Lxr-general] Problem installing: "The directory / does not exist"

[Dr R. <drr...@gm...>]

Hi,

Old issues are solved now, but substituted by new ones. Here's current
situation.

By moving sources from "/home/admin/indexed-src/SW_200936/" to
"/testFolder/SW_200936/" solved most of the problems. Currenly sources can
be browsed via web interface and identifier search works ok. Remaining
problem is general search. Even if I search text that is included in indexed
files for sure, I get reply "0 files found." and error "*Version 'SW_200936'
has not been indexed and is unavailable for searching.*"

There seems to be one reported bug that is related to this same issue with "
*Version 'XXXXXXX' has not been indexed and is unavailable for searching.*".
I wonder is this fixed into lxr version lxr-0.9.6 or fixed at all.

LXR loads the source files directly from there, they are not saved in
the database.

This is puzzling - as far as I can see the configuration is correct
and you should be seeing the source files.

Can you confirm that genxref has successfully put data in the database
- ie you saw a log of each file processed when you ran genxref, and
the database has contents?  If that's the case then LXR can definitely
find the code.

When you say the portal displays fine at http://myip/lxr/source/, do
you mean you see the LXR header etc but where you would expect to see
a listing of the top level directory of the source code you see "The
directory / does not exist"?

If none of those provide a eureka moment then could you try adding
some debug prints to LXR to see what's going wrong?

- At around line 150 of source, where it reads:
  151 @nodes = $files->getdir($dir, $releaseid);
  152 	unless (@nodes) {
  153 		print(  "<p align=\"center\">\n<i>The directory " . $dir
  154 			  . " does not exist.</i>\n");

Can you add a print of $releaseid and $files

Then in lib/LXR/Files/Plain.pm at line 99
  99    sub getdir {
  100 	my ($self, $pathname, $releaseid) = @_;
  101 	my ($dir, $node, @dirs, @files);

Add a print of $pathname, $releaseid, and at line 108
107 	$dir = $self->toreal($pathname, $releaseid);
  108 	opendir(DIR, $dir) || return ();

add a print of $dir which will show what directory LXR is trying to open.

Hopefully one of these will reveal what's going wrong!

Cheers,

Malcolm

Yes it does. It and its sub directories also all have read and execute
rights for u/g/o (which might not be a good idea, but I wanted to make sure
it's not causing problems). Is Apache looking for the source files directly
from there or from the DB?

Looking at the config file, your source code should be in the directory:

/home/admin/indexed-src/SW_200936/

does this directory exist?

The general pattern is that the source code lives in $sourceroot/$version/

where $version is one of the versions configured for $v in the lxr.conf file.

Hope this helps!

Re: [Lxr-general] Problem installing: "The directory / does not exist"

[Malcolm B. <mal...@gm...>]

It sounds like there's some misconfiguration in the lxr.conf file.
Can you post the file?

And don't worry, LXR works fine with Symbian C++ (since I used to work
for Symbian!)

[Lxr-general] Problem installing: "The directory / does not exist"

[Tommi H. <to...@dr...>]

Hi!

I've installed LXR 0.9.6 on Centos 5.3.
Using aAache2, mySQL, Swhish-e

I've followed all the installation instructions and (hopefully) have
remembered to execute all the steps.

http://myip/lxr/source/ displays the portal fine, but doesn't show any
source code. It says "The directory / does not exist."

LXR is in /usr/local/lxr/
The source code itself is in /home/admin/indexed-src, which has been
configured to lxr.conf. (src is Symbian C++, please don't let that
affect=
:)
Swish-e has written 3 files in /home/admin/swish-e/
The mySQL DB was configured by initdb-mysql and genxref has written into
it.


Right now I'm running out of ideas what to check next. Please ask more
details about my environment / setup, the above probably doesn't have
all
the needed info.

Thanks for any help!

[Lxr-general] Large installations running on Postgres?

[Malcolm B. <mal...@gm...>]

Hi,

I'm wondering what the performance (dis)advantage is of having
DBI::AutoCommit switched off for Postgresql.  As part of a general
tidy-up of the Index classes I'm considering switching AutoCommit to
on - but I don't have a decent-sized install to check the performance
impact.

Has anyone got a large-ish installation running using Postgres who
could measure the performance with AutoCommit switched on and off -
the relevant line to change is line 43 in lib/LXR/Index/Postgres.pm.

Any data would be much appreciated!

Cheers,

Malcolm

[Lxr-general] LXR needs your help!

[Malcolm B. <mal...@gm...>]

Shockingly LXR has managed to get to v0.9.6 and thousands of downloads
without one of the crucial elements for a great piece of software.

No, not a great UI.

No, not lots of features.

No, not even very few bugs.

What LXR lacks is a logo.  How can LXR hold its head up in the
pantheon of free software when it is handicapped, nay crippled by such
a dreadful lack?

I say enough is a enough.  No longer must LXR make do with three
simple letters - from now on LXR shall have a logo to dazzle, impress
and wow its friends.

This is a call to create that logo for LXR and win fame and fortune
around the world.  (OK, I'm kidding about the fortune.  And the fame.
But anyway...)

I'm no graphic artist, as will be obvious from the feeble attempt
attached.  So please, if you can do better then send in your
suggestions and ideas to lxr...@li....  The winner will be
selected by members of the LXR mailing lists, so get your pixels or
paintbrushes out and show the world what you can do!

Cheers,

Malcolm

[Lxr-general] LXR updating

[Nicholas T. K. <nic...@ce...>]

Hello,

I'm trying to look up code in the LXR for 
SUSYBSMAnalysis/Zprime2muAnalysis/ in CMSSW_2_1_0.

I am able to check out the code, but I am unable to see it in 
http://cmslxr.fnal.gov/lxr/source/SUSYBSMAnalysis/

This simply confuses me.  It would seem that if I can check out code for 
this CMSSW release, it would be in the LXR for viewing / searching. Help?

     Thank you,
        Nick Kypreos

I'm fine with it, but I haven't even really recognized that there's a
lot of spam coming from this list. My two-staged spam filter seems to

Hi,

Due to the large amount of spam this list is seeing, I'm considering

Unless there is a significant objection I'll do so in the near future.

This is standard Unix behaviour: You can open any file with proper
priviliges (knowing its filename beforehand), but to open a directory
(needed for reading the filenames within), you need a complete chain
of e'x'ecure rights for all directories back to / .
