      Description

      Tested and reproduced on XE 7.4.2
      Before testing, you must have these configurations:

      • Set Maximum Upload Size to 1073741824 by editing XWiki.XWikiPreferences in Object mode
      • Set max_allow_packet to 1073741824 bytes (1073 MB) inside MySQL
      • Set -Xmx2g inside Tomcat.

      1. Login with Admin and create a page.
      2. In this bug you will find the files I`ve tested with.
      2. Attach to this page files xls,pdf, sql, mp3 .
      3. While they are loading, attach quick the png.
      4. Now, attach quick again all files xls,pdf, sql, mp3, png.
      5. Wait some minutes to finish loading and check the state of each attachment.
      6. Check also tomcat logs.

      Actual result:

      • The upload of some files will crash and will generate in the bottom of the page this error: "An error has occurred while uploading document..."
      • If you check the tomcat logs, you will find:
        WARN  o.h.u.JDBCExceptionReporter    - SQL Error: 1062, SQLState: 23000
        ERROR o.h.u.JDBCExceptionReporter    - Duplicate entry '1610061591' for key 'PRIMARY'

      • If you attach once all 4 files, they will be successfully uploaded.
      • If you attach these 4 files + another file (while these 4 are loading) and again all 5 files, you will get the error.
      • You will notice in the screen shots that first version of png file was created successfully. The second crashed.
      • I must mention that this scenario is not happening only with bigger files.

      Expected result:

      • I expect to not be able to upload the same file twice if the first one is still loading. For each time I upload the same document, a new version of this document is created. So 1st version must be created successfully to be able to create a 2nd one.
