Priority: medium
Bug ID: 70537
Assignee: [email protected]
Summary: FILTER: Bad performance/unable to open 3.3MB Excel XML
file
Severity: normal
Classification: Unclassified
OS: Linux (All)
Reporter: [email protected]
Hardware: Other
Whiteboard: BSA
Status: UNCONFIRMED
Version: unspecified
Component: Spreadsheet
Product: LibreOffice
Problem description:
When I got the problem file I was running LO 3.6.4.3-3 (as downloaded from
www.libreoffice.org). I then upgraded to 4.1.2.3-3 to see if it would help,
but the problem persists.
Calc can't open a spreadsheet generated by another system. Calc freezes for a
long time and eventually pops up an error message that reads:
General input/output error.
[Retry] [Cancel]
Retry does not help.
Clicking Cancel results in another error message saying:
General Error.
General input/output error.
[OK]
Excel complains that the format doesn't match the extension (or something like
that) and after clicking on OK it opens the file in a fraction of a second.
The file is a plain XML file. Not an Office OpenXML file. The first tag looks
like this:
<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet"
xmlns:x="urn:schemas-microsoft-com:office:excel"
xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet"
xmlns:ns0="http://netcare.co.za/xi/hl7_data";
xmlns:o="urn:schemas-microsoft-com:office:office">
Steps to reproduce:
1. Open badperf.xls
2. See CPU spike and Calc freeze for about 1 minute.
3. See I/O error messages.
Current behavior:
Calc freezes for about one minute, using up 100% of one core before displaying
an error.
The file does not open.
Expected behavior:
The file opens successfully in a reasonable amount of time.
Operating System: Ubuntu
Version: unspecified
