Re: [Bug 1768166] Re: Random crashes

[Ping-Wu]

I tried your ibus-pinyin ppa; the problem still persists.  I will explain
that in better detail later.  Basically, after 18.04 (no problem there),
ibus-pinyin fails to update the hierarchy of an "entered" word or phase in
the "candidate list".   This is one of the most important features of a
Chinese input tool.  Without it, thhis tool is unusable.

The Chinese Ubuntu forum member who helped testing ibus-libpinyin 1.11
(百草谷居--btw, he is also a CPA）mentioned two important features that are
lacking in ibus-libpinyin which actually also prevented him from using this
input tool (except for doing this test).  Both features are available (&
kicking) in ibus-pinyin.

However, my most critical concern is always about stability.  I have used
the same old ibus-pinyin Chinese input tool since 18.04 daily built first
became available and have not had any problem.  As I mentioned in previous
communications, for some unknown reason ibus-pinyin doesn't work well in
Fedora/RedHat (though it can be installed without any problem), in reasons
probably similar to why ibus-pinyin is not working well in 19.04/19.10.
This is the main reason that I am not too thrilled about Fedora.

* My own verification measures according to comment #23

* The reporter of bug #1829947 expressed a positive testimony as to

[Bug 1768166] Re: Random crashes

[Ping-Wu]

I followed the steps as described in #24 and have tested the new ibus-
libpinyin 1.11 in 18.04.2 for more than two weeks.  So far, I have not
encountered any sudden crash problem as experienced in 1.10.

Moving the proposed upgrade of ibus-libpinyin and associated
dependencies to bionic-updates should be a no-brainer. As I mentioned
prior, I couldn't find anyone in the Chinese Ubuntu forum who is using
ibus-libpinyin.  No one can tolerate an input tool that will
"eventually" crash--and cannot be recovered unless the user possesses
certain CLI skills and is willing to delete the user-established
vocabulary that is the most important part of a Chinese input method.

That said, the most important question is, whether the upgrade of ibus-
libpinyin as proposed adversely affects other packages?  I have not
noticed that upgrade of ibus-libpinyin as proposed affected any of my
daily operations.  One of the Chinese Ubuntu forum members ("百草谷居士") who
agreed to participate in the testing, also expressed that there is no
interference with other packages.  This is what he wrote:

"功能上还是老问题：不支持拼音输入特殊符号；紧随数字的逗号和句号不能自动转换为半角符号。
然后发现汉字里面夹杂了不少表情符号，我觉得奇怪，既然可以夹杂表情符号，为什么不能加上特殊符号呢
目前在终端、gnome桌面、geany、libreoffice中使用正常。"

(No problem with gnome-terminal, gnome desktop apps, geany,
libreoffice.)

With the above-mentioned positive results, I recommend that the proposed
move should go ahead.  Indeed, if Ubuntu wants to regain its China
market, this is a necessary first step.

[Bug 1768166] Re: Random crashes

[Gunnar Hjalmarsson]

Hello,

This is a friendly reminder of my "call for testing" about a week ago.

Before moving the proposed upgrade of ibus-libpinyin and friends to
bionic-updates, it would be highly desirable to get feedback from a few
users who speak Simplified Chinese. So if you can help with this, and
assuming you are on a 18.04 machine, you find the details about how to
install from -proposed in comment #24 of this bug report.

Re: [Bug 1768166] Re: Random crashes

[Ping-Wu]

Duly noted.

I am hitting a brick wall in the Chinese Ubuntu forum.  It turns out that
nobody is using the ibus-libpinyin input method.

Would you be interested in using, as part of your daily routine, an input
tool that can suddenly crash and cannot be recovered until you delete all
the vocabulary that you have painstakingly built?  I won't blame them.

Switching to a different Chinese input method is much more involved than
you may think.  Even temporarily.  I might be able to personally force one
or two Chinese Ubuntu forum participants to test your proposed changes.
But that's about it for now.

[Bug 1768166] Re: Random crashes

[Gunnar Hjalmarsson]

@Ping-Wu: Which tools for inputting Chinese should be available on
Ubuntu going forward is indeed a valid discussion, but this bug report
is not a proper place for it. I notice your strong interest in the
topic, and if you want to start such a discussion, I would suggest that
you start a thread at .

For Ubuntu 18.04 we have the tools which are in the archive, and ibus-
libpinyin ("Intelligent Pinyin") is the default method for Simplified
Chinese. This bug (filed by yourself) is about upgrading the software
for that method, and only that.

So can we please focus here on testing the proposal to upgrade, and hold
the wider discussion in e.g. the Ubuntu Community Hub?

Re: [Bug 1768166] Re: Random crashes

[Ping-Wu]

I have been hearing this swan song for several years now that ibus-pinyin
is being or has been deprecated.  Actually it is a miracle that ibus-pinyin
still works in Ubuntu--*and only in Ubuntu*.  For unknown and very strange
reasons, I can never make ibus-pinyin work in Fedora, or even in Debian.
Indeed, this is the main reason that I am sticking with Ubuntu, even though
I was one of the very first supporters of the Fedora Linux when it was
being developed at the University of Hawaii.

Most Linux users in the Chinese Ubuntu forum actually use Sogou pinyin
(搜狗拼音）, this is a proprietary program running on the fcitx input
framework.  Sogou pinyin is definitely better than ibus-libpinyin (very few
people actually use ibus-libpinyin), but is inferior to ibus-pinyin in
terms of speed and stability.  We have a pro bono project in Honolulu
teaching seniors to be proficient in computers. Since many of our students
are of Chinese descent, our program also includes teaching them how to
input Chinese characters.  Ibus-pinyin has been our choice of Chinese input
tool because of its snappiness and being trouble-free.  You would think
that these two characters should also make ibus-pinyin a favorable Chinese
input engine?  But since so few people in China are using Linux desktops,
logic doesn't make sense.  It is the so-called upstream developers (mainly
Peng Wu of Red Hat), or the lack thereof (ibus-pinyin developers), that
prevails.

Based on my interactions with many Chinese Ubuntu forum elders, I am NOT
surprised that the upstream developers do not think highly of ibus-pinyin.
The reasons are three-fold: first, they are not using the right distro
(i.e., not using Ubuntu); second, they did not install a Ubuntu-specific
ibus-pinyin database (i.e., system-wide vocabulary); and third, they have
not used ibus-pinyin long enough (i.e., they do not have their own user
vocabulary).

I think upstream developers do not like ibus-pinyin also because it does
not have many bells and whistles (e.g., inputting emojis which I absolutely
could care less).  But ibus-pinyin also has some of the critical features
that are lacking in ibus-libpinyin.  For example, the latter cannot
conveniently input special symbols (many in the Chinese Ubuntu forum think
this a main reason not to use ibus-libpinyin).  Also, ibus-libpinyin will
treat a decimal point as a Chinese period, such as 19。04 (which should be
19.04）.   But most important AFAIC, ibus-pinyin uses a simple,
straightforward sqlite database structure that is very easy to comprehend.
How the table-lookup database is structured in ibus-libpinyin is
complicated and undocumented.

Many members of the Chinese Ubuntu forum have a very negative attitude
towards ibus-libpinyin partly because of the personality of its principal
developer Peng Wu.  They have always complained about being contemptuously
snobbed when they visited the ibus-libpinyin GitHub forum (many were told
to switch to Fedora).  I myself also could never get a straight answer from
Peng Wu.

I sincerely hope that your effort to make ibus-libpinyin stable ("stable"
in an absolute sense) will help attracting more users--ibus-libpinyin in
specific and Ubuntu in general.  I will definitely use it at least
occasionally to make sure that everything is OK.  Should Ubuntu
powers-that-be make an unfortunate decision and drop ibus-pinyin from its
archive, I will simply freeze my version of Ubuntu at 18.04, which is now
turning out to be exceptionally good.

[Bug 1768166] Re: Random crashes

[Gunnar Hjalmarsson]

@Ping-Wu: ibus-pinyin will soon be removed from the archive.

$ zcat /usr/share/doc/ibus-pinyin/NEWS.Debian.gz
ibus-pinyin (1.5.0-5) unstable; urgency=medium

Package ibus-pinyin is now deprecated; its upstream has stopped development
for years in favour of new ibus-libpinyin. New ibus users should install
ibus-libpinyin instead of this package. This package (ibus-pinyin) will be
removed after Debian Buster (Debian 10) release.

 -- Boyuan Yang   Tue, 18 Sep 2018 16:53:42 -0400

Seems like it won't be present in the Ubuntu 20.04 archive.

So let's focus 100% on ibus-libpinyin at this bug report.

[Bug 1768166] Re: Random crashes

[Gunnar Hjalmarsson]

Call for testing


I hope for help by both Ping-Wu (the bug reporter) and other Chinese
users to test the proposed upgrade of the ibus-libpinyin package in
Ubuntu 18.04. I have subscribed the Ubuntu CJK Testers team to this bug
report to reach out to more possible testers.

"Intelligent Pinyin", which is provided by ibus-libpinyin, is the
default input method in Ubuntu for inputting Simplified Chinese. While
we want to address the crash problem reported in this bug, we want to
minimize the regression risk.

The new versions of the affected packages are available in bionic-
proposed. These are the steps to install them:


1. Enable bionic-proposed
-

* Open Software & Updates and select the "Developer Options" tab.

* Check the "Pre-released updates" option.

2. Update the package information on your system


sudo apt update

3. Install/upgrade the packages
---

sudo apt install ibus-libpinyin libpinyin-data libpinyin13

(Please note that it's not sufficient for this test to only upgrade
ibus-libpinyin.)

4. Disable bionic-proposed
--

* Open Software & Updates and select the "Developer Options" tab.

* Uncheck the "Pre-released updates" option.

5. Update the package information on your system


sudo apt update


With that your system is back to normal, except for those three packages from 
-proposed. You can confirm that you got the right versions by using this 
command:

dpkg-query -W ibus-libpinyin libpinyin-data libpinyin13

It should show this info:

ibus-libpinyin  1.11.0-1ubuntu0.18.04.1
libpinyin-data:amd642.2.2-1~ubuntu18.04.1
libpinyin13:amd64   2.2.2-1~ubuntu18.04.1


Then I simply ask you to use "Intelligent Pinyin" for your daily needs, and 
submit a comment here after a few days about your experience. Any kinds of 
comments are helpful, both "works well" and info about issues you stumble upon. 
Most important, of course, is that no new issues are introduced via this 
upgrade.

Thanks in advance for your help with this!

Installed from cosmic-proposed these packages:

* ibus-libpinyin 1.11.0-1ubuntu0.18.10.1
* libpinyin-data 2.2.2-1~ubuntu18.10.1
* libpinyin13 2.2.2-1~ubuntu18.10.1

Used the Intelligent Pinyin method for inputting some Chinese
characters. Didn't observe any oddities.

fcitx-libpinyin and ibus-libzhuyin
--
Installed fcitx-libpinyin 0.5.3-1 and ibus-libzhuyin 1.8.2-1 from 
bionic-release, and libzhuyin13 2.2.2-1~ubuntu18.04.1 from bionic-proposed.
Used
- the Pinyin (LibPinyin) (Fcitx) method (on Unity)
- the New Zhuyin method
for inputting some Chinese characters. Didn't observe any issues due to the 
upgraded packages built from libpinyin.

Successfully rebuilt the bionic-release versions of fcitx-libpinyin and
ibus-libzhuyin with libpinyin 2.2.2.

Conclusion: We can stay with the current bionic versions of fcitx-
libpinyin and ibus-libzhuyin. Upgrading those would be beyond the scope
of this bug.

** Description changed:

  [Impact]
  
  ibus-libpinyin has proved to crash far too often. One or more files in
  ~/.cache/ibus/libpinyin get corrupted somehow, and emptying that
  directory allows the user to keep using ibus-libpinyin.
  
  In disco (and eoan) ibus-libpinyin 1.11.0 and libpinyin 2.2.2 are
  present, and the number of crashes has been reduced significantly:

  I have experienced random ibus-libpinyin crashes in bionic.  I cannot

  official bionic release.  Same crashes were also reported in the Ubuntu
  Chinese forum.
  
  Currently, the workaround is to delete the ~/.cache/ibus/libpinyin
  folder.
  
  I talked to Peng Wu, ibus-libpinyin's creator and main maintainer, he
  suggested that we update the version of ibus-libpinyin to 1.10.
  
  Can we give this update a trial?

[Bug 1768166] Re: Random crashes

[Łukasz Zemczak]

Currently ibus-libpinyin FTBFS on bionic-proposed, but this is unrelated
to the changes in our package. There seems to be some SRUs ongoing there
(particularly one for libio-socket-ssl-perl) that are causing some
installability issues for gnome-common. It's a long dependency chain
leading there, but yeah. Anyway, I have informed the people driving the
other SRU to see what we can do to resolve the issue - maybe it's just
transient?

[Bug 1768166] Re: Random crashes

[Łukasz Zemczak]

So generally, with my SRU hat on, after a longer discussion with Gunnar
I think we should give the backport a spin - but under specific
conditions. We would be keeping the SRU in -proposed for longer than 7
days and I'd appreciate some wider-testing during that time (maybe some
call for testing?).

Re: [Bug 1768166] Re: Random crashes

[Ping-Wu]

As I stated in the Chinese Ubuntu forum, I almost always stick to only the
LTS versions of Ubuntu.  I made an exception wrt 18.04 LTS and moved up to
19.04 and even 19.10 because ibus-libpinyin 1.11 is not available in
18.04.  However, 19.04 and 19.10 have their own problems and are not
recommended at least for now.

[Bug 1768166] Re: Random crashes

[Gunnar Hjalmarsson]

I have hesitated about upgrading, since the problem seems to have been
present also with version 1.10 according to the crash reports.

However, in Ubuntu 19.04 ibus-libpinyin was upgraded to 1.11, and it
looks like there is a significant reduction of crashes in 19.04 compared
to 18.04 and 18.10.

https://errors.ubuntu.com/?package=ibus-libpinyin=month

So I'm going to do this now.

I just encountered the problem again, after upgrading to libpinyin-1.10.0, but 
we can temporarily
solve the problem if we delete this two file:

~/.cache/ibus/libpinyin/opengram.dbin
~/.cache/ibus/libpinyin/user_bigram.db

and I got in this bug again, after deleting it for about 20 days

[Gunnar Hjalmarsson]

This problem in Bionic has also been reported via bug #1768192, which I
have marked as a duplicate of this one. Ubuntu's error tracker reports
quite a few occurrences of crashes with ibus-libpinyin 1.9.2-2:

https://errors.ubuntu.com/problem/cd3fa9b145c79364f535cede0267ffe384b9ced8

So we should really make a Bionic SRU to deal with it.

@Gunnar Hjalmarsson: yep, I had frequent crashes and that upgrading via
the PPA fixed the problem. I have using it for a week and didn't find
any problem, maybe the upgrading solved the problem.

Re: [Bug 1768166] Re: Random crashes

[Ping-Wu]

I don't know if upgrading via the ppa actually solved the random crash
problem, but I never had any crash after the upgrade.  There could be other
reasons including gnome upgrades.  But AT LEAST upgrading via the ppa did
not cause any negative effects.  Thus, I suggest applying the
ibus-libpinyin upgrade to the newer version for Ubuntu 18.04.1.

Thanks.  I have posted the new ppa to the Ubuntu China forum.  Believe it
will be greatly appreciated.

Try to compile it (Ubuntu 18.04), got the following error message:


configure: error: Package requirements (
ibus-1.0 >= 1.5.11
) were not met:

No package 'ibus-1.0' found


Execution of dpkg -l ibus command shows that the ibus version is
1.5.17-3ubun amd64 .
