Yep, it opens within 5 seconds for me

A new bug report seems the smarter choice. It only causes trouble & confusion
tracking the bug; IMHO

OK, let's do that. So I profiled this with callgrind and as far as I see the
next thing we could do is to improve the sdext/ code to produce flat ODF which
has no replacement graphics, since it'll be just discarded on ODF import
anyway.

But that always worked like this, so then let's not call this a regression.
Basically Noel already did what I would have done when it comes to fixing the
perf regression. Thanks.

These are my findings:

in

Version: 5.3.0.0.alpha1+
Build ID: 4136757b4e51c4e6f7cb4132c95538a7f831ef2c
CPU Threads: 4; OS Version: Linux 4.15; UI Render: default; VCL: gtk3; Layout
Engine: new; 
Locale: ca-ES (ca_ES.UTF-8); Calc: group

it takes

real0m10,072s
user0m9,171s
sys 0m0,250s

in

Version: 6.2.0.0.alpha1+
Build ID: a20a2d7e0d28658f2d9089da076961a599833a28
CPU threads: 4; OS: Linux 4.15; UI render: default; VCL: gtk3; 
Locale: ca-ES (ca_ES.UTF-8); UI-Language: en-US
Calc: threaded

it takes

real1m54,790s
user1m50,198s
sys 0m0,787s

and in

Version: 6.4.0.0.alpha0+
Build ID: 850693273970be2662cce8f4d2710b3657a02f65
CPU threads: 4; OS: Linux 4.15; UI render: default; VCL: gtk3; 
Locale: ca-ES (ca_ES.UTF-8); UI-Language: en-US
Calc: threaded

it takes

real0m40,405s
user0m36,665s
sys 0m0,444s

so in master and 6.3 it's much better than 6.2, but not as good as it was in
5.4 ( 4 times slower for me ). I think it's fair to keep it open

This improved a lot in the 6.2 -> 6.3 timeframe. Oldest 6.3 is around 50s for
me, newest 6.3 is rather in the 20s range. Reverse bisecting points out:

commit bd44b3eef62f4325a189539d6ab1b90ca63cfc28

tdf#89522 PERF FILEOPEN xlsx, part 1

Inherit from tools::WeakBase non-virtually, so that we can use a
static_cast in tools::WeakReference::get instead of a dynamic_cast.

This takes the file-open time from 1m21 to 40s for me.

Add a clang plugin to make sure we don't accidentally end up inheriting
from tools::WeakBase more than once.

Thanks Noel. :-) I guess we can close this, then.

--- Comment #7 from QA Administrators  ---
Dear Dmitry Yakimov,

To make sure we're focusing on the bugs that affect our users today,
LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed
bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this
bug report. During that time, it's possible that the bug has been fixed, or the
details of the problem have changed. We'd really appreciate your help in
getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice
from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information
from Help - About LibreOffice.

If the bug is NOT present, please set the bug's Status field to
RESOLVED-WORKSFORME and leave a comment that includes the information from Help
- About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular
meaning that is not 
appropriate in this case)


If you want to do more to help you can test to see if your issue is a
REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your
bug pertains to a feature added after 3.3) from
http://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword


Feel free to come ask questions or to say hello in our QA chat:
https://kiwiirc.com/nextclient/irc.freenode.net/#libreoffice-qa

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
QA Team

tdf#107392 ODF import: fix z-order sorting of SVG images
The problem was that in case the document has shapes where the order
does not match the z-index order, so sorting is needed, then sorting
failed to take the multi-image feature into account. E.g. SVG images
have a PNG fallback, but at the end of the shape import the PNG
fallback is removed, which means the "actual" (not the "wished") z-index
of the shapes after the SVG image has to be adjusted.

Without this happening SvxDrawPage::getByIndex() (or in case of Writer,
SwTextBoxHelper::getByIndex()) will throw when the importer calls
getByIndex(3) but we only have 3 shapes. This results in not honoring
the z-index request of the remaining shapes.

Regression from commit 44cfc7cb6533d827fd2d6e586d92c61d7d7f7a70 (re-base
on ALv2 code. Includes (at least) relevant parts of:, 2012-10-09), from

Confirmed.

The pdfium Insert filter rather than pdfio Open filter (to Draw by default)
handles the rotated table pages without issue.
