Description: When opening large text content (over a few megabytes) in Writer, the loading time takes minutes, and then it slows down so much that even the basic functions are unusable. Steps to Reproduce: 1: Open the attachment in Writer. Actual Results: It loads the attachment very slowly and is then unusable. Expected Results: It loads the attachment quickly and you can work with it.

Unfortunately the test file is too big for bugzilla (76 Mb) Therefore, create your own text document using the following code snippet.: $ seq 10000000 | tr '\n' ' ' ' >numbers.txt $ soffice numbers.txt The problem detail is unchanged except for the attachment.
Regression from commit 745898eb2af2686ffbdfdc0e44984db67b172a59 "tdf#70423 Remove txtimport break in 10k chars line"

Commit description: tdf#154000 tdf#70423 sw: fix crash/freezing with huge text files It was not possible to load or edit text files with very long lines any more, because removed wrapping of the lines resulted freezing and crash. This reverts commit 745898eb2af2686ffbdfdc0e44984db67b172a59 "tdf#70423 Remove txtimport break in 10k chars line", keeping only its unit test. Fix also tdf#70423 by increasing the wrap limit from 10000 to 250000 characters, which still permit to load e.g. 50 MB character or longer text lines, and to edit 5 MB or longer text lines without crash or freezing. Details: trying to load a relatively short 76 MB character length text line shows a non-linear slowing down during the load, resulting program crash after freezing 10 minutes. Now this file is opened within seconds again, allowing to modify, select and copy of the text before the full load of the document (with linear speed). Loading a much shorter 5 MB character length text line resulted an unusably slow editing previously: waiting half minutes for changing, selecting or copying text parts. Manual test Create a text file with a 76 MB character long line, and open it: $ seq 10000000 | tr '\n' ' ' >numbers.txt $ soffice numbers.txt Note: the reverted commit had also a paragraph limit exceeded error using unlimited paragraph length, because that is limited in 4 GiB characters since version 4.3, see tdf#30668 and commit ba27366f3d6bc6b209ecd5c5cb79a9ee5315316a "Resolves: #i17171# Writer paragraph cannot be longer than 65534 characters".
