SID-01547: PublishWebPlugin causes hang on save of EditTable table

Status:	Unanswered	TWiki version:	5.1.1	Perl version:	5.10
Category:	PublishWebPlugin	Server OS:	RedHat 6.2, kernel 2.6.32	Last update:	10 years ago

I have both PublishWebPlugin and EditTablePlugin installed. They both appear to be working normally except when a user tries to save an edit to a table using the EditTablePlugin feature.

Any page which has a table that uses the EditTablePlugin can be edited and saved normally (i.e editing the page and saving). But if you just edit the table using the little button at the bottom of the table there is a hang. The edit commits, but something somewhere times out and the result is a 504 error.

Discussion and Answer

The data/debug.txt log contains about 6,000 lines of the following per table save attempt.

| 2012-10-03 - 14:55 | - PublishWebPlugin: afterSaveHandler( TestPage ) | 2012-10-03 - 14:55 | - PublishWebPlugin: publishTopic( DemoLab, TestPage ) | 2012-10-03 - 14:55 | - PublishWebPlugin: commonTagsHandler( TestPage )

The log indicates the save and the warn log doesn't have any entries related to the attempt.

The apache logs gives some pointers (IP's and site names redacted)

I've updated my EditTablePlugin to the 2012-07-11 version per bug Item6900. but I still get the timeouts and errors.

The errors now start with this in the httpd error log
