[TxMt] Re: "Half focused" windows bug

[Graham Heath]

Hello again,

Unfortunately my previous letter's solution is not much of a solution. It's
only temporary and, in retrospect, I’m not even sure its more effective
than quitting and relaunching TextMate. I must have tried that at the time,
but I don’t recall doing so.

I’m back to basics, disabling and re-enabling bundles on whims.

This time around I’m suspicious of the machine itself. It seems odd to me
that sometimes even the most minor changes in a small text file can cause
my TextMate to hang for up to 6 or 7 seconds. It seems like if I switch
from and back to TextMate while its saving I frequently get the "half
focus" state to reproduce. Does this sound familiar?

Ed, and anyone else interested, are you using the Save On Focus Lost
bundle? Or something another bundle that has a command thats triggered on
"callback.application.did-deactivate"?

What about .bash_profile, could introducing a delay there be causing the
delay on save?

And finally;

Is there a chance that TextMate and my development scripts (gulp
<http://gulpjs.com/> w/ file monitoring and lots of tasks) are introducing
some sort of file lock, that TextMate is failing to resolve?

I’ll work to answer these questions on my own, but I’m concerned (and
optimistic) that I’ll no longer be able to reproduce these issues when I
upgrade to my new machine.

Thanks,

Graham Heath

Hi Graham,

I can’t reliably reproduce it so I don’t think my use cases are going to be
any help. For instance I haven’t experienced this problem in a few weeks
because it shows up sporadically for me, not enough to be a major nuisance.
But it is annoying when it happens and I start typing and nothing shows. :-)

Times I’ve seen it happen is when I have a lot of files open in one window
(> 30) with some of them extremely large files so it could be a speed issue
as you’ve mentioned in the past. My main level machine is a vintage 2011
MBP but I’ve upgraded it with a 1TB SDD so it’s not too bad, just the CPU
is showing it’s age at times. The other one is a recent MBA and I’ve never
had it happen on that one.

Hello Ed, All,

None of my previous theories worked out, but I think I’ve had a break
through on this.

I can trivially reproduce it now by switching between iTerm2 and TextMate,
very quickly. Finder might work too, but I’ve been using iTerm. The key
seems to have less to do with which app, and more to do with how fast. My
machine is slow which may make the problem worse.

What I do know is if I reset my configs to their defaults (by removing
~/Library/Application Support/TextMate), this problem is eliminated. Adding
folders back one at a time TextMate still works until I add the
Session/Info.plist back.

I’ve attached my info.plst and made a video of what I see while I’m working
on this; https://youtu.be/C0nyIr5_dTQ

Ed, does removing this file do anything for you?

Everyone; Does this make any sense? Does anyone know where to begin solving
this bug? I sure don’t.

Thanks,

Graham Heath

Graham, I don’t have Diff Gutter enabled, just the standard line numbers,
folding arrows, bookmarks in the gutter.

Thanks for the answers. What all is happening here is still a mystery but
I’ve got an update;

I’ve now had 24 hours without incident. My current theory is this relates
to SCM Diff Gutter, as after disabling it I haven’t seen the issue, but
thats just a theory. I’m re-enabling Emmet today, and I’ll add my linters
tomorrow.

Ed, do you have SCM Diff Gutter, or anything adding icons to your gutter?

Thanks,

Usually many windows with many tabs. Some windows are minimized (those that
I’m not actively working on at the moment).

2: have a customized window bar title?


Yes - full document path.

3: have expensive to render documents?


A few files with > 5000 lines but generally < 1500 lines of PHP, ObjC,
HTML, JS or CSS. Some customizations done to PHP bundle and Mac Classic
theme.

4: SCM integration?


Git on some projects.

Hope this helps.

Some days are worse, maybe better after a reboot, but thats not for sure.

Some more theories for you Ed, and anyone else :)

Do you …

Here’s what I’m thinking _might_ be happening for each of these. Hopefully
one of these sparkles for someone.

1) TM is confused about what tab / window should have focus, and fails to
pick one.
2) I have a pretty complex stack of replacements to build my window title,
perhaps one of these replacements has a edge case that causes an error
3) TM may be selecting the right tab, but the selection doesn’t happen in a
reasonable time and aborts
4) The timing between focus and TM failing to select a tab seems related to
when the title bar updates when SCM is working

I’ve been experimenting with disabling plugins and add ons. Today I’m going
to try disabling the SCM plugin :(

If that doesn’t work I guess I’ll build TM and see what I can find. Short
of building it, there’s not a way better debug this issue, is there?

Thanks,

Graham Heath

Hi Graham,

My TM setup is pretty basic. No plug-ins, Shell Support installed, Git
support sometimes depending on the project.

I think Allan may be right though as I’ve seen this behaviour with Safari
and Finder as well so it could be an general OS issue.

Allan, I’m sorry to say, that this is behavior that I associate with
TextMate, not the os at large. I will keep an eye out for it and let you
know if I change my mind. But, as you’ll see below, I don’t really blame
your code either, I’m just wondering whats causing it. Its so erratic that
its probably not something simple.

Jacob, Ed, and others; Do you have any plugins? I haven’t done the full
reset, but I have disabled things that I feel might be offending. Its too
early to say, but I wonder if a plugin might be triggering when the app
gets focus, but something isn’t going quite right.

Tossing this on the pile; I’m using a early 2013 mbp that does seem to have
issues with apps hanging or freezing fairly often, so maybe whatever’s
causing that, is causing this.

Thanks,

Graham Heath

This issue has existed with macOS for as long as I can remember, and I
have seen it for other apps as well, though it is visually much more
obvious with TextMate because of the tabs bleeding into the title bar.

I do not think the issue is with any of my code, since window management
is not the responsibility of the individual app and I am not aware of
code in TextMate that could affect this.
