[CWB] CQPweb could not create a directory for the frequency index

[Hardie, Andrew]

The code that generates this error is quite simple – it’s just a mkdir calll:

          if (! mkdir($datadir))
                   exiterror("CQPweb could not create a directory for the frequency index. Check filesystem permissions!");

There must be something at the system level stopping the directory being created (that is, the directory {$your_corpus_index_data_directory}/{$name_of_corpus}__freq )being created. If the directory is owned by www-data, perhaps you should check whether user has permission to write to this directory?

On the basis of the other issue you report, the problem may be that an earlier run of the frequency-table setup code has created a __freq directory that cannot be deleted. Then, mkdir fails, because the directory already exists (because it could not be deleted).

The message “has already been created” indicates that that __freq directory does exist (which should only be the case if frequency table setup was successful).

My advice: manually remove the __freq corpus (its data directory and registry file). Then check all relevant filesystem permissions. Then, once you’re sure they are correct run frequency list setup from scratch.

If in doubt use offline freqlists instead of the interface buttons; that may give more informative error messages if there is still a problem.

I get this error when I try to "Cretate the CWB Frequency table"
CQPweb could not create a directory for the frequency index. Check filesystem permissions!

But there is no error for text position records or frequency tables,

directories:  registry, data and cqpweb are all owned: www-data:www-data

but then if I refresh the Corpus frequency list controls page, I can see: The text-by-text list for this corpus has already been created.


Another problem that I still have is the creation of new users:

A MySQL query did not run successfully!

Original query: INSERT INTO user_info ( username, realname, email, passhash, acct_status, expiry_time, acct_create_time, conc_kwicview, conc_corpus_order, cqp_syntax, context_with_tags, use_tooltips,
thin_default_reproducible, coll_statistic, coll_freqtogether, coll_freqalone, coll_from, coll_to, max_dbsize, linefeed ) VALUES ( 'jhuser', 'unknown person', 'jhuser at upf.edu',
'$2a$11$......................yl0Kl8h3xhUATbrHP7sKOq.GXmLA0AS', 0, 0, CURRENT_TIMESTAMP, 1, 1, 0, 0, 1, 1, , 5, 5, -3, 3, 1000000, 'au' ) /* from User: admin | Function: do_append_mysql_comment() | 2016-Oct-13 19:02:22 */

Error # 1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' 5, 5, -3, 3, 1000000, 'au' ) /* from User: admin |
