Priority: medium
Bug ID: 79207
Assignee: [email protected]
Summary: Large paragraph: Slow editing and looping
Severity: normal
Classification: Unclassified
OS: All
Reporter: [email protected]
Hardware: x86 (IA32)
Status: UNCONFIRMED
Version: 4.3.0.0.beta1
Component: Writer
Product: LibreOffice
Background:
Does the welcome new large single paragraph allow reasonable editing?
Test document attached has 700k characters, about 10 times original maximum for
a single para but much less than the new maximum. It's the size of a medium
length book.
Edits attempted are typical of those that would be needed to reformat a poorly
formatted manuscript in a completely standardised way for publication. I have
used this technique successfully before with MSO.
In summary, LO is not yet up to this job.
Win 7/64; 24Mb memory; i7 processor
Steps to reproduce etc:
Do regular expression replace $ with ###NEW### to create a single large
paragraph. Takes c50 sec, no progress bar.
(Ctrl+Z takes c 37 sec, no progress bar)
In single para created as above, attempt to replace ARB with rabb
Progress bar is slow to appear and progress is very slow. After around 15 mins
at about 2/3 complete, the editing results appears at the top of the document
and get the dialogue box: To proceed with this action, you must first turn off
the "undo" function. Do you want to turn off the "undo" function?
Answer ‘yes’ to the prompt.
Control is not returned to the user, even after an extended wait (>> 1 hour),
so assume LO is looping (it's still active in task manager, but 'not
responding'.
A similar and more likely edit, replacing \s+ with a single space is even
slower (about 10% complete after >>1 hour). It does not reach the 'turn off
undo' dialogue and does not return control to the user. The number of edits
required is almost exactly the same as the other one.
Expected result:
Progress bar at all stages
Faster editing
Edit completed and control returned to user for any answer to the 'turn off
undo' dialogue
