8 years ago I found it.
with:
/usr/local/bin/flake8 --version
2.5.0 (pep8: 1.5.7, pyflakes: 1.0.0, mccabe: 0.3.1) CPython 2.7.9 on Linuxinstalled elpy stops working
uninstall flake8 and all problems gone .. but flake should be nice ....
forget it, it wasn´t flake8, on my other maschine the syntaxchecker was the case, but not here :(

8 years ago Thanks for the report! This sounds very weird – can you do M-x toggle-debug-on-quit and use C-g again to get out of the locking? This should produce a backtrace, could you post that here? Thank you!

8 years ago Thank you! Emacs is apparently hanging trying to send data to the Elpy process. Which would indicate that Elpy is not actually reading data, but hanging in some loop.
When this happens, can you check with top (and P) whether the Elpy process is consuming 100% CPU? Either way, could you do an strace like you did for Emacs on that process?
I'm suspecting Rope as the primary culprit, but I could be wrong. If you want, try uninstalling Rope and see if that fixes the problem? :-)
Sorry for this somewhat aimless debugging here. This is a weird problem.

8 years ago Same problem without Rope? Did you M-x elpy-rpc-restart?
That confuses me a lot now. The Elpy process you show does not actually do anything, so it should keep reading from stdin. And as such, Emacs should not block.
I'm afraid I'm at a loss there :-(

8 years ago yes same problem without rope, i started emacs completly new
first i thought i has to do with the oh-my-emacs config package, but the same affect with a new plain setup and your installation howto ....
when i start with an empty test.py, completion works for 2 lines, after some lines more nothing ... happens ... some lines more and it hangs.
if i open a file with about 50 lines it happens faster that emacs hangs

8 years ago Same problem here, using emacs 25.1.50.2 on Ubuntu 14.04, latest version of elpy. Output after toggle-debug-on-quit looks similar. If I can provide any other helpful input, please let me know.

8 years ago @webhamster sent me the backlog in private mail, the lock happens in the same place: process-send-string. That's incredibly confusing. That can only mean that Elpy's input is blocked and it does not accept further input, so it's consuming slower than it receives data. But that should mean the Elpy process is using up all CPU. Apparently, it isn't.
@webhamster, can you confirm that? The Elpy process is not consuming CPU time?
danielfett
commented
8 years ago Yes, can confirm, no significant CPU load caused by either emacs or elpy process.

8 years ago Yay. Shotgun debugging! To verify if this is really the problem, please evaluate this form. The *Messages* buffer then will contain messages listing the duration of each such call. Does the duration increase over time, and is comparatively large when Emacs has locked up?
(defun elpy-rpc--call (method-name params success error)
"Call METHOD-NAME with PARAMS in the current RPC backend.
When a result is available, SUCCESS will be called with that
value as its sole argument. If an error occurs, ERROR will be
called with the error list.
Returns a PROMISE object."
(let ((start (float-time))
(promise (elpy-promise success error)))
(with-current-buffer (elpy-rpc--get-rpc-buffer)
(setq elpy-rpc--call-id (1+ elpy-rpc--call-id)
elpy-rpc--last-call (float-time))

(method . ,method-name)
(params . ,params)))
"\n")))
(message "elpy-rpc--call duration %s" (- (float-time) start))
promise))Will run the debug script as soon as the next lockup happens (restarted elpy just now).
NB: strace should show new output when I scroll through a file (it should show that the get_calltip request and others are received, right)?
Because mine does not. This is the only strace output directly relating to elpy since elpy was started. Since then, nothing happened. [pid 23354] lstat("/home/daniel/.emacs.d/elpa/elpy-20160131.118/elpy/main.py", {st_mode=S_IFREG|0644, st_size=551, ...}) = 0 [pid 23354] futex(0x7facf0903a04, FUTEX_WAIT_PRIVATE, 1, NULL <unfinished ...> [pid 23351] <... read resumed> "{\"id\":3,\"method\":\"get_calltip\",\""..., 4096) = 160 [pid 23351] futex(0x1814640, FUTEX_WAIT_PRIVATE, 0, NULL

8 years ago Huh. That's really strange.
What's the value of default-process-coding-system in Emacs and os.linesep in Python?
danielfett
commented

8 years ago Ok, that's not the problem, then. I remain confused! :-)
danielfett
commented
8 years ago Well, I tried the debug script above, but it does not create any output when elpy has crashed and I have to abort with C-g.
jorgenschaefer
commented
8 years ago It should cause output when Elpy tries to send more stuff to the backend. As in, if you have to C-g things, evaluate that, and continue to work, it should emit things to *Messages*. Or does Emacs lock up right away again when you go to a Python buffer?
danielfett
commented
8 years ago This is what it looked like: elpy-rpc--call duration 0.0004696846008300781 <-- non-crashing output elpy-rpc--call duration 0.0009064674377441406 <-- non-crashing output, at the next cursor movement the crash happened Quit [3 times] <-- I pressed C-g ... <- other unrelated output
To help with debugging, I added the following lines into read_json in elpy/rpc.py:
with open('/tmp/elpy-debug-python-server.log', 'a') as f:
f.write(line[:120] + "\n")The output shows an interesting behavior: For every "project" that I open, output is created upon each cursor movement... until it suddenly stops after some messages (3, 10, 7, then 18, see below). Even though I continued to move the cursor, no new output was created until I opened a file in a different folder. I didn't try long enough, but probably elpy will soon start to crash again.

8 years ago Hm. Can you add os.getpid() to the output, to check if that's a new process every time?
Also, does the following lock up after some time?
(let* ((buf (get-buffer-create "*Elpy Test*"))
(process-connection-type nil)
(process-environment (elpy-rpc--environment))
(proc (start-process "Elpy Test" buf "/bin/cat")))
(display-buffer buf)
(sit-for 0.1)
(with-current-buffer buf
(let ((n 0))
(while t
(process-send-string proc (format "Line %s\n" n))
(setq n (+ n 1))
(sit-for 0.01)))))Different "projects" yield different pids, yes. It looks like the longer the messages are, the earlier the crash happens (smells like a buffer running full).
The script above does not crash even after 8000 messages (added about 100 characters after Line %s to make the messages longer).

8 years ago I added the following code to read_json:
line = ""
with open('/tmp/elpy-debug-python-server.log', 'a') as f:
f.write(str(os.getpid()))
f.write(" ")
while True:
byte = self.stdin.read(1)
f.write(byte)
f.flush()
line += byte
if byte == "\n":
breakreplacing the line = ...readline() stuff.
The output of this does never break in the middle of a message (tried 4 times and with long JSON messages).

commented
8 years ago Oh, but it also never stops with just the PID written to the file, meaning that elpy does not wait for new messages, but is occupied itself.

You're missing f.flush() to be certain of that, I think?
danielfett
commented
8 years ago Yes, that came to me just right now. With flush, the output ends after the pid. So the server IS waiting.

8 years ago Emacs is doing something very weird there. Does this reproduce the problem?
(with-temp-buffer
(python-mode)
(elpy-mode)
(let ((n 0))
(while t
(message ">>> %S" (elpy-rpc "echo" (list n)))
(setq n (+ 1 n))

8 years ago Thank you! 26611 is Emacs, 26684 is Python, 26687 is some thread within Emacs I think.
[pid 26611] read(19, <unfinished ...>
[pid 26611] <... read resumed> "{\"result\": [1065], \"id\": 1067}\n", 4096) = 31This is the last time Emacs actually reads from fd 19. Shortly thereafter, it sends another request:
[pid 26611] write(18, "{\"id\":1068,\"method\":\"echo\",\"para"..., 44 <unfinished ...>
[pid 26687] <... open resumed> ) = -1 ENOENT (No such file or directory)
[pid 26611] <... write resumed> ) = 44
[pid 26684] <... read resumed> "{\"id\":1068,\"method\":\"echo\",\"para"..., 4096) = 44
[pid 26684] futex(0x1d6b6a0, FUTEX_WAIT_PRIVATE, 0, NULL <unfinished ...>
[pid 26611] pselect6(20, [3 7 8 11 19], [], NULL, {1, 0}, {NULL, 8} <unfinished ...>Here, Emacs sent the last JSON-RPC method call. Elpy responds a bit later:
[pid 26684] write(4, "{", 1) = 1
[pid 26684] write(4, "\"", 1) = 1
[pid 26684] write(4, "i", 1) = 1
[pid 26684] write(4, "d", 1) = 1
[pid 26684] write(4, "\"", 1) = 1
[pid 26684] write(4, ":", 1) = 1
[pid 26684] write(4, "1", 1) = 1
[pid 26684] write(4, "0", 1 <unfinished ...>
[pid 26684] <... write resumed> ) = 1
[pid 26684] write(4, "6", 1) = 1
[pid 26684] write(4, "8", 1 <unfinished ...>
[pid 26684] <... write resumed> ) = 1
[pid 26684] futex(0x1d6b6a0, FUTEX_WAIT_PRIVATE, 0, NULL <unfinished ...>Then it hangs. The line is incomplete, but Python does not try to resume sending here. Actually, it does not do anything at all. It hangs.
I'm not even sure how it would do that, I mean Elpy is doing self.stdout.write(json.dumps(kwargs) + "\n") – it's not like it's doing anything in Pythen when emitting those things.
It would be interesting to see the Elpy backtrace. Could you see if you can get Python to produce a backtrace there? E.g. using https://stackoverflow.com/questions/132058/showing-the-stack-trace-from-a-running-python-application or similar methods?
Elpy should show the backtrace automatically. If not, it might be hiding in the *elpy-rpc...* buffers.

8 years ago (Hope this helps or I can get some help.)
When elpy is enabled, Emacs hangs frequently, even in Shell-script mode. And, when elpy is disabled, no hang any more.
No process consumes significant CPU when Emacs hangs.
I think elpy interfered with company-mode, or my scheme of tweaking Emacs does something wrong.
All used packages are cloned from their repositories (checking out master branch),
and with no other preparation nor installation operation
except adding the following lines in my ~/.emacs.d/init.el.
Elpy and its Emacs Lisp dependencies.
(add-to-list 'load-path "~/.emacs.d/vendor/company-mode/")
(require 'company)
(add-hook 'after-init-hook 'global-company-mode)
(add-to-list 'load-path "~/.emacs.d/vendor/pyvenv/")
(add-to-list 'load-path "~/.emacs.d/vendor/highlight-indentation/")
(add-to-list 'load-path "~/.emacs.d/vendor/yasnippet/")
(require 'yasnippet)
(yas-global-mode)
(add-to-list 'load-path "~/.emacs.d/vendor/elpy/")
(require 'elpy)
(elpy-enable)Say, keep the following lines in init.el.
(add-to-list 'load-path "~/.emacs.d/vendor/elpy/")
(require 'elpy)
(elpy-enable)Say, comment the following lines in init.el.
(add-to-list 'load-path "~/.emacs.d/vendor/elpy/")
(require 'elpy)
(elpy-enable)Step 1. Open a non-existent shell script file (Yes, shell script), e.g. emacs test.sh.
Step 2. Enter /root (/ will activate path completion, you may try other paths like /foobar),
and then C-a (a.k.a move-beginning-of-line), C-k (kill-line), C-x C-s (save-buffer).
Step 3. Repeat Step 2 about 10 times or so.
With Elpy enabled, Emacs hangs frequently after typing /root,
which leaves me no chance to continue.
I can C-ggg and continue experiments.
With Elpy disabled, no hang observed.
If Elpy is enabled, frequent hangs are observed when completing path in C-x C-f (find-file)
and M-! (shell-command).
Emacs continues to hang even I checked out the 0.8.0 release of compay-mode,
with other packages also checked out to the version specified in elpy/Cask.

For more information about these matters, see the file named COPYING.@NoviceLive, that is some excellent report and debugging, thank you!
The problem you encounter is that find-file tries to run tramp, and tramp then tries to ssh to some unknown host, which hangs Emacs. (I personally hate tramp with a passion because it rarely works well for me and most of the time just breaks, like in this case, so I disabled it completely, but that might not be an option for everyone)
Elpy does not actually do anything with tramp, so I am a bit confused why that would happen.
Can you try and (setq elpy-modules nil) before (elpy-enable) and see if the problem persists?
If yes, can you try to replace all of the Elpy configuration with the following and see if one of them is the culprit?
(require 'cus-edit)
(require 'etags)
(require 'files-x)
(require 'grep)
(require 'ido)
(require 'json)
(require 'python)Thanks for pointing it out. Let me see. (I just started learning Emacs Lisp.)

8 years ago (setq elpy-modules nil) before (elpy-enable): Emacs hangs as usual.
Comment (require 'ido) will not hang!
(require 'cus-edit)
(require 'etags)
(require 'files-x)
(require 'grep)
(require 'ido)
(require 'json)
(require 'python)Huh. Looks like even just loading ido is hooking up tramp somehow, which gives you a broken file-finding history. This sounds like a bug to me.
If you replace the whole Elpy stuff with just (require 'ido) and that hangs Emacs, I think you can M-x report-emacs-bug :-(

I am getting this issue on Emacs 25.3.2, Ubuntu 16.04. Things get sluggish and my laptop started breathing heavily. htop shows it is the elpy process taking 100% of one of my cores and (after some waiting around) never coming out of that loop. Using elpy-restart-rpc gets things back to normal, but it happens again a few minutes later.
I had been working most the day and didn't change anything in my config when this started happening... however - I noticed something strange. I was in customize-group ENT elpy. I saw the option Show Value Elpy Profile Visualizer... I clicked on it and, well, it disappeared! After that, the menu-bar buttons were not working either! If I click on e.g. YASnippet, I just see and empty grey box appear. If I hit f10 to cycle through the menu-bar items, I get the functionality back. But this behaviour then continues. I have tried logging out and back in, as well as simply restarting emacs/elpy/python process etc - didn't help.
Could these things be related? Both symptoms of something else?

6 years ago Hello, and thanks for the report. Can you post the output of M-x elpy-config? Does the problem go away when you uninstall importmagic?
As for the second problem, I have no idea I'm afraid :-(

There is a newer version of Jedi available.
[run] python3 -m pip install --upgrade jedi
The yapf package is not available. Commands using this will not work.
[run] python3 -m pip install yapf
The configured syntax checker could not be found. Elpy uses this
program to provide syntax checks of your programs, so you might want
to install one. Elpy by default uses flake8.
[run] python3 -m pip install flake8Which doesn't make sense for flake8 or importmagic as they are both installed, in both the environment as well as site site-packages of Anaconda. You can notice that I set the WORKON variable to the anaconda environments and not virtualenv, which works great. Can't imagine that is causing the menu-bar issue.
The hanging, I thought, might be something to do with me using ipython as the interpreter, but that has also been working today without any issue. I think there may be a bug there when loops are sent. If I run e.g.
for i in range(1000):
do_something(args, i)... then either cancel the loop or not, I believe there is some broken link between elpy, ipython and python, which leaves the loop running. This is the only explanation I have right now.

6 years ago Is the flake8 command available for Emacs? That's what elpy looks for.
Does the hanging go away if you uninstall importmagic?
Nicholas-Autio-Mitchell

6 years ago It works in Emacs with a simple command and a more extravagent one.
If I just run python-check and pass the string flake8 file.py --> it works
If I run python-check and pass flake8 --ignore=E266,E501 --max-line-length=100 file.py --> it works
I have actually fixed my problem by using flycheck, which allows me to specify the flake8 config file setting the variable flycheck-flake8rc.
I still don't know for sure if this issue is linked to the hanging processes or not. I haven't had a hanging elpy/python process since I configured things using flycheck. But that was only yesterday ;)

The hanging issue is still occuring. I took a screenshot of the process shown in Terminal's htop:
You can see if is the elpy.__main__ file that is stuck.
It seems to happen after I have had the error:
Company: backend elpy-company-backend async timeout with args (candidates so)
I did once try to increase the time Company is allowed to find completions, but that didn't help.
Turning of company by deactivating global-company-mode did not help, but executing elpy-rpc-restart did.
I updated all packages in Emacs and things seem to be running a little smoother. Interestingly, I got this output in the buffer *Elpy Output*, after about 15 minutes of use:
Output from Backend
There was some unexpected output from the Elpy backend. This is usually some module that does not use correct logging, but might indicate a configuration problem.
Output /home/n1k31t4/anaconda3/envs/env-name/bin/python3: Error while finding spec for 'elpy.main' (ImportError: No module named 'elpy')

6 years ago Elpy uses a bunch of libraries. In that case, it should use jedi. That seems to be stuck in some kind of loop, apparently? Try upgrading Jedi?
Hi there, i´m new to elpy and my emacs hangs after a while.
beginning to type "import argp" works with a tooltip and completion and then no more ...
after writing some lines more emacs hangs completly
strace the emacs process:
with C+ggg emacs comes back and hangs again C+gggg M+x elpy-rpc-restart and i can write some lines
First i thought with the oh-my-emacs config collection is sometthig wrong, but some behavior with a plain setup
My versions:
i checked the related issues but with no success ...
any ideas?
Cheers
