Dear CWB developers,

We have installed two separate corpora and added alignment using
command-line CWB methods. However, when we conduct a query, the results
still do not show any alignment.

I am not sure where I should look to identify and resolve this issue. Could
you please provide some guidance on troubleshooting the CWB alignment
process?

Thank you for your help.

conduct a query, it says no alignment found.

Subject: [CWB] Upgrade of CQPweb server
Message-ID: <50a17441-961d-477d-9d7c-9eff289bd827@uni-saarland.de>

Hi everyone,

I would like to upgrade a server running CQPweb. I am aware of the system administrator's manual, but this server was not set up by me. Therefore, I would like to ask a couple of questions in advance to avoid potential pitfalls.

We want to upgrade from Ubuntu 22.04 LTS to 24.04 LTS. Has anyone faced issues with that upgrade? I vaguely remember that an earlier Ubuntu upgrade caused some problems due to changing defaults.

As far as I can see, only Perl will be affected by a major version change. The MySQL version seems to remain the same. I guess that means I'll have to reinstall cwb and cwb-perl from SVN. Our current system (cwb, cwb-perl, CQPweb) is based on revision 1826.

We were also thinking about an update of CQPweb (revision 1826, 3.3.17). However, I am somewhat uncertain about the version policy of CQPweb. The website (https://cwb.sourceforge.io/cqpweb.php#install) mentions 3.3.15 as the latest version. Where, in terms of stability, does revision 1826 stand? Is there a more recent revision that provides the same level of stability?

I checked the administrator's manual and could not find any necessary migration steps for 3.3.17 or later. Does that mean that I can simply compare r1826 with the latest SVN revision and merge any changes into the installed .php files?

While going through the current .php files, I found files named like the following examples:
usr/31/index.php
usr/4a/index.php
...

Do they serve a purpose? They all contain the same line of code:
<?php exit(1);

Finally, is it possible to restrict access to the administration interface (/adm/) to an IP range or would that break any functionality for regular users?

Thank you in advance!
Stefan

? we're still on CQPweb v3.2.44 because 3.3 is still considered unstable / incomplete and we didn't have the courage to upgrade. Did you upgrade your server from 3.2 to 3.3 at some point? And if so, did you have major issues due to the upgrade?

You could also simply install CWB from the .deb-package and cwb-perl from CPAN. Though it's always best to use the latest and least buggy versions from SVN, of course.

Yes, these are weird. We've got two such subdirectories on our CQPweb server (with different numbers), created 5 years apart.

>>Yes, these are weird. We've got two such subdirectories on our CQPweb server (with different numbers), created 5 years apart.

Short explanation: It's a security plug.

Long explanation:

This directory structure is how user-installed corpora are accessed. The system of directory naming (reflected in the URL) is

... / usr / (hex code of first byte of username) / (username) / (underscore then base-36 ID of corpus)

(why split the accounts up according to first byte? cos I have 40,000+ user accounts on my server)

By default, if a browser accesses a folder, Apache EITHER serves up the "index.html~php~whatever", if there is one, OR otherwise prints the directory's content list.

Therefore, making the byte-code directories (and user directories) content-listable over the web would expose usernames (plus the number of corpora each user has installed).

Having an index.php file that runs but produces nothing - ie "<?php exit(1);" - blocks Apache from serving the folder list. Anyone poking around just gets a blank page.

So whenever one of these folders is created (by a user installing a corpus), it's given such an index.php file.

It's probably better in some abstract sense to fix these issues via Apache config, etc. but that would need to be set up by every server admin separately (and procedure would be different for every web daemon). This way doesn't have that issue.

In retrospect I probably should have made them symlinks rather than separate files though, just for tidiness. Ah well, hindsight's a wonderful thing.

best

Andrew.

Did fixing the s_id then fix the alignment display problem?

Hi Stefan,

Re Ubuntu upgrade - it *Should* be OK. I hesitate to say "will" because Ubuntu upgrades have a way of surprising me. But to the best of my knowledge...

Re CQPweb. Stephanie mentioned the version issues. Version 3.3 does have known bugs, but not that many. If you are on 3.3.x already, there is no reason not to upgrade to the latest version on the repo.

The website is not up to date on version numbers, so don't worry about that. The latest in the repo ought to be 3.3.18.

>> Finally, is it possible to restrict access to the administration interface (/adm/) to an IP range or would that break any functionality for regular users?

Doing that should not break anything as far as I can think. The only difference for regular users is that if they go to /adm, they will get whatever your server is configured to provide upon an attempted access to something forbidden, rather than the CQPweb-internal error.

best

Andrew.

The website (https://cwb.sourceforge.io/cqpweb.php#install) mentions 3.3.15 as the latest version. Where, in terms of stability, does revision 1826 stand? Is there a more recent revision that provides the same level of stability?

I checked the administrator's manual and could not find any necessary migration steps for 3.3.17 or later. Does that mean that I can simply compare r1826 with the latest SVN revision and merge any changes into the installed .php files?

While going through the current .php files, I found files named like the following examples:
usr/31/index.php
usr/4a/index.php
...

Do they serve a purpose? They all contain the same line of code:
<?php exit(1);

Finally, is it possible to restrict access to the administration interface (/adm/) to an IP range or would that break any functionality for regular users?

Thank you in advance!
Stefan

Hi Stephanie,

Thanks for looking up the release number. That's already reassuring.

> ? we're still on CQPweb v3.2.44 because 3.3 is still considered unstable / incomplete and we didn't have the courage to upgrade. Did you upgrade your server from 3.2 to 3.3 at some point? And if so, did you have major issues due to the upgrade?

The earliest CQPweb version mentioned in our documentation is 3.2.31. So, I guess that we upgraded successfully from 3.2 to 3.3. However, that happened before I took over administration of the server. I found a short note that installing r1826 caused an issue related to "php upgrade-database.php". Apparently, this was fixed by removing some "saved_catqueries" for the corpus with id=0. I hope that helps.

After you mentioned upgrade issues, I had a closer look at our database. Luckily, all upgrade steps in upgrade-database.php were applied successfully. However, I noted that there are still some MyISAM tables. I guess, before any other upgrades, we should fix this by calling force-innodb.php?

> You could also simply install CWB from the .deb-package and cwb-perl from CPAN. Though it's always best to use the latest and least buggy versions from SVN, of course.

Thanks for mentioning the .deb and CPAN packages. I'd actually prefer these to a manual installation. However, r1826 (2022-10-15) seems to be a couple of months newer than the available .deb and CPAN versions. Could that downgrade cause any issues with a newer version CQPweb? That is, does the unstable version of CQPweb depend on minor bug fixes?

Best,
Stefan

Hi Andrew,

> Re Ubuntu upgrade - it *Should* be OK. I hesitate to say "will" because Ubuntu upgrades have a way of surprising me. But to the best of my knowledge...

Thanks, that is already helpful.

> Re CQPweb. Stephanie mentioned the version issues. Version 3.3 does have known bugs, but not that many. If you are on 3.3.x already, there is no reason not to upgrade to the latest version on the repo.

Well, now I am getting cautious ... Luckily, the current revision works for us and no issues were reported by our users. Maybe, we don't use the more advanced features.

Best,
Stefan

That's good to know. I was concerned that there might be a problem with the user database as the number of files and their creation dates looked random.

Thanks for the detailed explanation and for making administration easier for us by implementing these clever features.

Hi Andrew,

Thank you for following up.

It seems that we are now running into a larger issue (when trying to fix
the alignment display problem). We accidentally removed the
/data/cqpweb/data/data directory with the command rm -rf
/data/cqpweb/data/data. (We then manually create a new ../data/data
directory)

The current situation is that we can no longer query existing corpora, nor
can we install new corpora. The error message is:

[image: image.png]
[image: image.png]


Is there anything we can do to recover or resolve this?

Best,
Qu Min

Hi Min Qu,
rm -rf is pretty drastic. Do you have a regular server backup routine? 
I'd suggest you try that, as I don't think you can recover much easily 
after this.
Best,
Graham.

Well that?s your problem ? all the indexes were in there. Recreating the directory doesn?t make the indexes come back. You?ve deleted all your actual data; all that?s left is the records about the corpora, but no actual text.

Failure to install new corpora is probably because the recreated directory has the wrong read-write permissions for the web daemon user.

If I were in your position I?d be tempted to scrub all the corpus records completely, fix the permissions, and start over from scratch, actually. Probably quicker than trying to repair things manually.

It seems that we are now running into a larger issue (when trying to fix the alignment display problem). We accidentally removed the /data/cqpweb/data/data directory with the command rm -rf /data/cqpweb/data/data. (We then manually create a new ../data/data directory)

The current situation is that we can no longer query existing corpora, nor can we install new corpora. The error message is:

[cid:image001.png at 01DC5A36.769BD450]
[cid:image002.png at 01DC5A36.769BD450]


Is there anything we can do to recover or resolve this?

Best,
Qu Min

Hi everyone,

I believe I have found the root cause of the alignment issue: I realized I forgot to include the s attribute (s_id) when installing the corpora.

I believe I have declared the parallel alignment on CQPweb. However, when I conduct a query, it says no alignment found.

Hello,
Have your declared the parallel alignments, using the left hand menu? You didn't mention this, which is the final step, after the command line stuff!

Objet : [CWB] Corpora alignment issue on CQPweb

Dear CWB developers,

We have installed two separate corpora and added alignment using command-line CWB methods. However, when we conduct a query, the results still do not show any alignment.

I am not sure where I should look to identify and resolve this issue. Could you please provide some guidance on troubleshooting the CWB alignment process?

Thank you for your help.

Best,
Qu Min

However, r1826 (2022-10-15) seems to be a couple of months newer than the available .deb and CPAN versions. Could that downgrade cause any issues with a newer version CQPweb? That is, does the unstable version of CQPweb depend on minor bug fixes?

CQPweb is designed for the stable release versions, so you should not encounter any issues. The main difference is that there are a few less bugs in the SVN versions ?

Steph

Hi everyone,

Thank you all for the quick responses and advice.

Following up on the catastrophic rm -rf issue, the action was taken by an
internship colleague who was attempting to fix the initial alignment
problem based on a set of external AI instructions. Unfortunately, we do
not have a regular backup routine for our CQPweb server.

The good news is that we currently only have 2 or 3 corpora installed, so
losing the indexes is manageable.

Thank you again for your guidance on how to recover from this.

Best,
Qu Min
