#4630 (4.3.3) AJAX request infinite loop

[Michael]

Hello,

we are using the same config as in 4.2.13. After upgrading to 4.3.1 we have the following issue:

• login with db user
• phpmyadmin homepage is shown as usual
• then a not ending AJAX request infinite loop is triggered till the browser crashes (tested with Google Chrome and Mozilla Firefox)

The request is sent to index.php, but it is not waited for the answer. The same request is sent immediately again (50+ per second in my case).

Here is some debug info:

Request Header:

Here is the rest of the bug report (sorry cannot edit original post):

JSON answer:

message "<div id="maincontainer">...dort vorzunehmen.</div>"
success true
_title  "<title>[my.domain.com]...hpMyAdmin 4.3.1</title>"
_menuHash   "335d1f47"
_menu   "<div id='floating_menuba...at"></div></ul>\n</div>\n"
_scripts [Object { name="jquery/jquery-1.8.3.min.js", fire=0}, Object { name="sprintf.js", fire=1}, Object { name="ajax.js", fire=0}, 18 mehr...]
_selflink "index.php?db=&table=&ser...4051747101c6e630ab13cca"
_displayMessage ""
_errors "<div class="clearfloat" id="pma_errors"></div>"
_promptPhpErrors false
_reloadQuerywindow Object { db="", table="", sql_query=""}
_params Object { common_query="?token=ffd6e14b84051747101c6e630ab13cca", opendb_url="db_structure.php", safari_browser=0, mehr...}

This request loops till the browser crashes with the same content again and again.

Best wishes

Does https://github.com/phpmyadmin/phpmyadmin/commit/8795f7a104e8bfa85c6df14a68927f0a9d88efaf commmit fixe the issue for you?

[Michael]

The patch does not fix the issue. The loop does still exist.

[Madhura Jayaratne]

From the Network tab of Chrome Developer Tool, can you tell me the Request URL where continuous requests are sent to.

[Michael]

Initiator:

send @ get_scripts.js.php?token=df6d00692befbcc14e29e93c1585ee37&scripts[]=jquery/jquery-1.8.3.min.js&scri…:2

Can you also tell me the value you get when you execute PMA_commonParams.get('LoginCookieValidity') on the Chrome console?

[Michael]

PMA_commonParams.get('LoginCookieValidity')
"2592000"

Fixed with https://github.com/phpmyadmin/phpmyadmin/commit/e79bfbdbeb949dfa0347b005a797b2bd322801cd

[Michael]

confirmed, no loop anymore

Thanks
