Description Walther 2012-12-16 17:37:25 UTC
An incorrect call to enchant_dict_check causes spell checking to mark as misspelled every string whose length in characters is different from its length in bytes. This bug was already reported and fixed upstream on the provided url (svn r125791), but it might be a long time before this fix reaches Gentoo's stable ebuild.

Since this bug affects all non-English language users, can I request the correcting patch be included in portage for the time being?

Reproducible: Always

Steps to Reproduce:
1. Launch a webkit-gtk application with enchant spell check enabled
2. Spell check for a foreign language word (e.g.: très français)
Actual Results:  
Enchant reports these words are misspelled.

Expected Results:  
Words are correctly spelled on selected dictionary.

Comment 1 Pacho Ramos gentoo-dev 2013-04-07 08:10:29 UTC
should be fixed in 2.0.x
Comment 2 Walther 2013-04-08 14:24:11 UTC
But webkit-gtk-2.0.0 is not stable yet. I wanted exactly to avoid forcing users to update to a testing version in order to get this bug fixed...

^ This looks like an inefficient solution for a one-line source-code bug. Should international users just stick to using their own overlay with the solution patch?
Comment 3 Pacho Ramos gentoo-dev 2013-04-08 17:31:35 UTC
I guess you are referring then to old slot (whose 1.8.x is the latest version), in that case I can try to apply it. 

Is this patch the one works for you?
Comment 4 Walther 2013-04-10 14:39:52 UTC
Yes, exactly. That's the patch that solves this bug. As far as I know, "the old slot" is still what is considered the stable version, so it isn't like I am requesting support for a deprecated package version.
Comment 5 Pacho Ramos gentoo-dev 2013-04-11 20:20:46 UTC
The patch is applied to a file that doesn't exist in 1.8.3 :|

enchant fix for webkit-1.8.3

Huh, oops. Didn't realize that the patch needed porting. This is the patch I use in my local overlay to correct this problem, for webkit-gtk-1.8.3

Comment 8 jospezial 2013-04-12 02:04:35 UTC
What the heck is this?

Sorry, but after a long time using Gentoo I have learned, there is a .r200 and a .r300 for webkit-gtk and I dont have to mix them.

webkit-gtk-1.8.3-r200.r1.ebuild would be a silly name I know so there will be no other choice for the naming as you chosed.
Have to like new ebuild names.

just wondering.
anyway, thank you for your bugfixing.
Comment 9 Walther 2013-04-12 05:44:59 UTC
I was always under the impression that the gtk2 and gtk3 slots for webkit-gtk were named -r200 and -r300 exactly to allow revisions in the way of -r201/-r301. It may seem a little dirty, but it was required to allow revisions and the separate slots.

Hence, this patch should also be applied to webkit-gtk-1.8.3-r301.ebuild.

Yes, this is needed to allow both versions installed at the same time

For people using latest SLOT, please try to use newer webkit-gtk as possible as I am nearly 100% sure 1.8.x versions have some unresolved security bugs that should be solved in newer releases, for example, I have seen two:

The problem is that I haven't tested 1.10.x at all (and probably 2.0.x will also fix some security issues over 1.10.x), then, I doubt about how safe would be to try to stabilize 1.10.x because it needs a libsoup version that need glib-2.34 (that is incompatible with Gnome2 and I haven't tested it at all :S)
