| Summary | 0002108: PHPMyAdmin fails with NullPointerException | ||||||||
| Description |
Tested phpMyAdmin 2.11.1.2 and found a NullPointerException caused by a null Env ref in the thread local Env table. This issue was reported on the quercus forum with the following trace: 500 Servlet Exception java.lang.NullPointerException at com.caucho.quercus.env.Value.toStringValue(Value.java:700) at _quercus._libraries._js_0escape__lib__php$fun_PMA_escapeJsString.call(D:/resin-pro-3.1.3/webapps/phpmyadmin/libraries/js_escape.lib.php:65) at com.caucho.quercus.program.CompiledFunction.callRef(CompiledFunction.java:56) at _quercus._index__php.execute(D:/resin-pro-3.1.3/webapps/phpmyadmin/index.php:127) at com.caucho.quercus.page.QuercusPage.executeTop(QuercusPage.java:119) at com.caucho.quercus.servlet.ResinQuercusServlet.service(ResinQuercusServlet.java:146) at com.caucho.quercus.servlet.QuercusServlet.service(QuercusServlet.java:353) |
||||||||
| Additional Information |
This problem seems to be the result of a missing call to Env.start(), so the thread local Env ref never gets initialized. |

After further review, the problem actually seems to be a result of a call to session_write_close near the top of index.php. This case seems to already be covered by the following QA test. php/1k6l.qa |

Verified that the attached patch fixes the 1k6l.qa test. |

The first NullPointerException issue is now fixed. Now I am seeingthe following error: 500 Servlet Exception com.caucho.quercus.QuercusExecutionException: java.lang.NullPointerException at java.lang.System.arraycopy(Native Method) at com.caucho.quercus.env.LargeStringBuilderValue.append(LargeStringBuilderValue.java:492) at com.caucho.quercus.env.LargeStringBuilderValue.subSequence(LargeStringBuilderValue.java:367) at com.caucho.quercus.lib.string.StringModule.trim(StringModule.java:4072) |
