Auto-completion broken and causing Sublime Text to hang

[anissen]

Here's a real-time GIF showing the problem in action:

The status bar reads "no info/hxml for flow file, caching..." (printet from here).

The console outputs this:

Traceback (most recent call last):
  File "/Applications/Sublime Text.app/Contents/MacOS/sublime_plugin.py", line 359, in on_query_completions
    res = callback.on_query_completions(v, prefix, locations)

The HXML-part of the JSON that is parsed in refresh_info in flow.py seems to be correct:

... and the complete JSON-data is valid JSON.

I'm running OS X El Capitan with Haxe 3.2.1 and the newest flow, sublime_flow and sublime_haxe. The problem started occurring after I upgraded to El Capitan, but not immediately after.

[hamaluik]

I can confirm the exact same behaviour but on OSX Yosemite, with (to my knowledge) nothing changing on the system from before breaking to after breaking.

[ruby0x1]

This is tricky to debug given that it's working fine for me on both my machines! I'm running sublime 3083 btw. Can either of you test re-installing the package? It almost looks as if the newer commit on 28 Oct may influence this but since I'm unable to get it to misbehave I can only start with narrowing down the obvious - a lot of which anissen has done on the validation front.

[anissen]

I'm running sublime 3083 btw.

Me too.

Can either of you test re-installing the package?

I've tried reinstalling sublime_flow but the issue persisted.

[ruby0x1]

Can you update both this and sublime_haxe and try again?

[anissen]

Can you update both this and sublime_haxe and try again?

I've updated both plug-ins and the issue still remains :cry:

[ruby0x1]

Check the console (sublime, view -> show console) for a message about how long completion took. I suspect this is some configuration issue that has nothing to do with the plugin itself.

[ruby0x1]

Can you uncomment and paste this line? https://github.com/snowkit/sublime_flow/blob/master/flow.py#L91

I know you pasted the HXML, but I want to see the full log please :)

[hamaluik]

Seems to be fixed for me, I'm getting things like the following:

[flow] saved file for completion
[haxe completion] complete
[flow] restore file post completion
[flow] completion took 0.642874002456665

[ruby0x1]

I'm still finding and fixing some issues that I found that might be related but is hard to tell. The JSON failing to parse is a red flag though.

[ruby0x1]

I've pushed the remaining fixes for now as well, let me know if that changes anything.

Quite rarely, I've managed to have it hang completely - but killall haxe (i.e kill the completion cache server) returns back to sublime, so the hanging is inside of the haxe executable. While it was hanging I sampled the app using the mac activity monitor, and it was in a stack inside neko regex stuff. I'm trying to track down a more reproducible case, testing against the latest haxe.

[anissen]

I've updated to the latest sublime_flow but it didn't fix my issue.

I've uncommented line 91 in flow.py but for some reason, I couldn't get sublime text to accept the changed package (some encoding error).

The error I'm getting seems to occur at line 89 (in decode) so I think I would need to write out the result of run_process(cmd) instead.

However, running haxelib run flow info web --project project.flow yields the following JSON:

Oh yea, if you want to change / debug, just uninstall the plugin via package control, then clone it into Sublime -> Preferences -> Browse Packages. as long as it's in the packages folder as a cloned repo folder it will pick it up, then hitting save inside of flow.py it will reload the flow plugin each save (but that will clear the flow file, so you set it each time you test or hardcode the path in the init to iterate fast).

[ruby0x1]

Yea that looks like a BOM character and a color sequence, interesting. So somewhere that invalid sequence up front is sneaking into the string, do you use any particular shell other than the default?

[anissen]

Yea that looks like a BOM character and a color sequence, interesting.

I think that may be the console in Sublime Text that inserted those characters? Anyway, on my laptop and work computer I've tried running the Python code to load just the HXML-part of the JSON (as shown above). On both computers (both running Python 2.7) I'm getting the error shown above. My Sublime Text runs Python 3.3.3

Doing some further tests, it seems that Python throws up if trying to parse JSON that contains newlines or \". Here's some command line tests showing the issue:

>>> json.loads('{ "hxml": "blah" }')
{u'hxml': u'blah'}

This works (do'h).

>>> json.loads('{ "hxml": "blah\n" }')

Later today, I can try changing flow.py to replace \n with space and \" with \\" and see if that works.

Edit: Haxe seems to have similar problems parsing the HXML: http://try.haxe.org/#79Fe2

[ruby0x1]

Yea, I find it curious however that for the last say year+ this hasn't come up before (and still isn't for 99%).

See the latest flow and sublime_flow commits, let me know if you see anything weird.

I've also been using the sublime_flow plugin in ST for months without issue but even after the latest updates to flow and the ST plugins, I'm still not getting any auto-completion:

This is on Windows 8 with Haxe 3.2.0 and ST build 3083 using Flow commit b8520ea244d62c3c929439eb7709451c01b1c5b4.

[ruby0x1]

For reference, the initial step (set as active flow file) is most relevant, everything is hinged on the set step working initially so any errors that result from trying to complete against invalid state may be misleading.

@ImDeity @anissen I pushed the logging to the console of the received json so it's easier to debug. I suspect whatever made the py JSON parser sporadically pedantic on some machines is potentially disliking the windows paths in the string.

@ImDeity can you paste the block that the sublime consoles prints out between these;

[flow] json source: >>

Updated to latest sublime_flow and on setting the active flow file, this is in console:

@ImDeity before you update can you run flow info on the command line and see what happens? I'm basically wondering how your hxml can be invalid, that's not a state that's expected in flow.

After that, can you update flow, and then paste the same section (which presumably may have an invalid hxml node rather than a crash log)

[ImDeity]

Output from flow info within project folder: http://pastie.org/pastes/10576161/text?key=uyjpqetlby1knbuten8m2g

Crash log on neither one (they seem identical).

That's definitely not right, but I consider that unrelated to this issue at hand. Can you open another issue, But start with pasting what sublimetext sees (since console seems fine) after commenting this line in flow itself (there is no rebuild step for flow or anything, just a quick test). https://github.com/underscorediscovery/flow/blob/master/src/flow/flow.js#L173

That should print more info (which will invalidate the sublime part, expectedly) but I'm curious why the state of your project when queried from sublime is somehow blank. I don't know a code path that can get there.

[anissen]

I really appreciate all your work in getting this to work. Unfortunately, it still doesn't :disappointed:

[ruby0x1]

Yea you can't escape the whole JSON, that won't work. "hxml" would become invalid json as \"hxml\", the keys are strings.

�(B�[m this is still printed in the output which bothers me.

Are you on the latest commits? I removed the logging but since you had a clone you edit it back in and try, I'm fairly certain that the logic is sound now, I put the new lines and >> so that we could pinpoint if those characters come from the result, or if they come from sublime. The above means that somehow your actual result from flow has some preceding characters that are breaking the json. I suppose one thing to try is to strip() the source, see if it takes those characters out before moving on.

[anissen]

I've found the best, most elegant solution to my problem!

Changing line 94 to self.info_json = json.loads(self.info_json_src[6:]) :P

It does in fact work! So the problem was the wild escape characters. However, auto-completion is not looking too hot either: I suppose it might be related. But I have no idea why or how there's escape characters everywhere...

[ruby0x1]

Yea, here's something you can run in the sublime console for debugging there,

import subprocess; t=subprocess.Popen(['haxe','-version'],stdout=subprocess.PIPE, stderr=subprocess.STDOUT).communicate()[0]; print(t.decode('utf-8'))

This just runs haxe -version but since that might not be found you could try /usr/local/bin/haxe instead, or any command. I'm curious if it does it from here too.

You might be able to mess with the decode option to see if you can output raw binary or hex to try and understand what byte sequence it's getting (instead of the replacement character).

[anissen]

Yea, here's something you can run in the sublime console for debugging there,

No escape chars:

>>> import subprocess; t=subprocess.Popen(['haxe','-version'],stdout=subprocess.PIPE, stderr=subprocess.STDOUT).communicate()[0]; print(t.decode('utf-8'))
3.2.1

You might be able to mess with the decode option to see if you can output raw binary or hex to try and understand what byte sequence it's getting (instead of the replacement character).

No decoding gives b'{.... I've tried a few others; utf-8-sig, utf-16, latin-1 that didn't give different results. I haven't been able to find a hex or binary encoding option.

[ruby0x1]

Btw I meant encode rather, i.e convert the raw output to viewable bytes, so we can see what the stream looks like. Often you can google a byte sequence like BOM, color codes etc.

Here's what happens in this set of commands:

• [sublime] set flow file calls the run_process, reads stdout/stderr
• [haxelib] haxelib run flow info --project <file> does run script
• [haxelib run] neko run script here
• [flow src/]* works out flow-local node binary path, calls Sys.command (prints to stdout/stderr)
• [flow.js] here, run by node, printed using console.log, and other output muted*

That's the end of the chain. I starred two things, above. First, maybe a custom build of haxelib or something is causing this, but it's somewhere to add logging and check if it's sane. Just run compile.hxml to rebuild that step. You can maybe pinpoint where exactly it gets transformed this way.

Second, the muted line, flow has verbose logging, forcing that to 3 or 4 instead of 0 might yield more information, you could look for the entry point and simple console.log('test') and try pinpoint where it's being mangled. This will generate invalid json (via prefixed logging in the output)
