weblinkchecker.py slows down (itself, OS) to freeze after a while reaching 100% of RAM
Open, Stalled, HighPublic

Description

Steps to reproduce

  1. run python pwb.py weblinkchecker -start:! -ns:0 on a large wiki (cswiki with 400 000 articles is enough)

Expected behavior
weblinkchecker.py should run through all pages in chosen namespace smoothly

Current behavior
weblinkchecker.py after some amount of time/pages read begins to slow itself down (let's say 1 hour). After another amount of time (2 hours) it slows also the whole OS by increasing RAM usage up to 100% (4 hours). It finally stops on 100% RAM usage when processing some page (>>> Some page <<< is the last what it outputs) and does nothing more (freezes). The whole OS (per RAM usage) is making itself slower until it freezes too. If I interrupt it by keyboard when RAM usage less than 100%, it usually says: Waiting for remaining 49 threads to finish, please wait...; on 100% RAM usage I can not do anything else than hard shutdown my PC (100% RAM usage makes the whole OS freeze).

Yes, I can set my OS not to reach 100% (still slows the whole OS after a while). Yes, I can limit weblinkchecker (pywikibot) to use only some memory max (OS and RAM ok, but weblinkchecker.py still slows and freezes itself). Yes, I can interrupt it after a while and start it from the last article checked (currently the best solution I think, I use timeout --signal=SIGINT 20m python pwb.py weblinkchecker -ns:0 -start:"Last article processed in last run" and hope the data will not be broken at the end). But I think there is some issue in weblinkchecker.py, maybe duplicite calling of threads or functions; or threads or functions not properly terminated after a success or fail; or maybe functions or threads exceeds some limits which should not. And this issue makes weblinkchecker.py slowly grow until it reaches the cutoff and freezes.

Configuration
Python 3.6.4, Pywikibot last master commit, OS: Arch Linux; 80 Mbit/s connection; 1,9 GiB RAM (+ 4 GiB of swap space)

@Dvorapa, Could you try https://gerrit.wikimedia.org/r/#/c/415687/2/scripts/weblinkchecker.py and see if it helps?
(It is not supposed to reduce the number of active threads, I'm hoping to control RAM usage by stopping page fetches while threads are full)

treat_page is sequential. No more than one extra page (not being processed by a thread) should be loaded at once.

Right, thanks, nevermind then.

I have not reproduced the problem of entire OS freeze yet, but what I can confirm is that the memory consumption of the script is increasing non-stop.

@Dvorapa:

  • Does the freeze only happen after the script reach near 100% RAM?
  • What is the CPU usage during the freeze? What is the state of the processes during the freeze?
    • I'm especially interested in the load (/proc/loadavg), # of threads in D-state (uninterpretable sleep), and the IO wait CPU %.

Oh, and if you are using Linux, really don't hard shutdown. I crashed one of my SSDs once (had to do some messy recovering, but went successful) and learned it the hard way. Linux kernel will process SysRq at #1 priority as long as the kernel is alive.

The script has frozen. No new threads have been created in a few minutes, according to strace). Getting a python traceback on all threads with gdb:

weblib.getWebCitationURL(url) received an error propagated from requests. The semaphore was not released.

Change 415771 had a related patch set uploaded (by Zhuyifei1999; owner: Zhuyifei1999):
[pywikibot/core@master] weblinkchecker: use with-statement to acquire and release semaphore

I will now start doing memory profiling and see what is using so much memory.

(Tests below are done with the patch above applied)

I forced garbage collection on each sleep with __import__('gc').collect(), but the memory usage kept increasing, so it is not an issue with garbage collection not running frequently enough.

For simpler memory profiling, I captured a few memory mem_top snapshots:

The most significant from my first read, is that, <class 'http.cookiejar.Cookie'> is being insane, from <1156 instances, to 12078 instances, to 66076 instances.

Will now look into its referrers with guppy.

Does the entire database have to persist in memory? If not I'll submit a patch to use dbm (py3 py2) instead. Yes it will be slower, but the gain is, the memory consumption can be much smaller and avoids OOM.

Like a rabbit hole. I'll implement it, but the estimated time of code review ... forever.

[pywikibot/core@master] weblinkchecker: use with-statement to acquire and release semaphore

https://gerrit.wikimedia.org/r/415771

I just realized there is the shelve module that wraps around dbm to make life easier, although in python 2 keys can’t be unicode. Good part is that it’s already used by interwiki.py so I might use it as a reference.

@Dvorapa:

  • Does the freeze only happen after the script reach near 100% RAM?
  • What is the CPU usage during the freeze? What is the state of the processes during the freeze?
    • I'm especially interested in the load (/proc/loadavg), # of threads in D-state (uninterpretable sleep), and the IO wait CPU %.

The script freezed, when it went to 49 threads openned. The OS freezed, when the script was working for more than a few hours. I don't know if this is a usual behavior, but my PC freezes every time RAM reaches 100% (It did on Ubuntu quite a lot when I openned like 200 tabs in Chrome and it does on Arch Linux now when I run weblinkchecker). The only option I know is to hard shutdown, neither switching to terminal interface, nor some magic key combinations work in this case. CPU usage when script freezes is normal or low, when OS freezes I've nnever tested.

I'll look into patches and test them tommorow. Thanks both Dalba and zhuyifei1999 for analysis and fixes. Is there something I can help with/test?

Fix your OOM killer :). Hard shutdown is for when the kernel itself crashes (and in my case I have kexec/kdump to avoid hard shutdowns in most of kernel crashes).

The script freeze was caused by a semaphore not being released properly, as least in one case. I was unable to reproduce it after the submitted patch is applied.
The OS freeze is most likely a memory leak, causing OOM condition. My memory profiling shows the giant memory usage is, at least in part, due to the entire history dict being processed entirely in memory rather than in disk. I'm investigating using shelve to workaround it (and submit a patch), and see if the memory still increase unbounded.

With https://gerrit.wikimedia.org/r/415771 there is still no difference for -repeat. It still behaves as I described in T185561#4015457

Please give me the traceback of:

I will, but I think this can be some error in the data file.

Currently I am trying to collect new data using https://gerrit.wikimedia.org/r/415771 and it works more smoothly, the memory consumption still slowly grows (from initial cca 200 MB to 500 MB now), but it seems to me threads are closed properly now, the script does not slow down much at all (It will when RAM consumption will be close to 100 %, but now on 90 % it works really fast).

It will when RAM consumption will be close to 100 %, but now on 90 % it works really fast.

That definitely sounds like an OOM condition.

Linux typically overcommits memory (see /proc/sys/vm/overcommit* in proc(5)), allowing more memory to be allocated via malloc(3) (which would return NULL if overcommit ratio is exceeded, or if overcommit is disabled and the system is out of memory) than the system actually has. This allows many programs to allocate more memory than the system actually has, and the system would not fail if a lot of memory is only allocated, but not used; otherwise the system would fail malloc(3) quite frequently due to many programs over-allocating.
The problem comes when huge chunks of memory have been allocated, exceeding the physical memory limit, and then large chunks of memory are actually used, exceeding the physical memory limit. As far as I understand it (may contain misunderstandings), when such condition occurs, and a program starts to use a new memory virtual address that is not backed by any physical address, a page fault occurs and the exception is sent to the kernel interrupt handler, which will put the currently running task into D-state (uninterruptable /IO wait sleep), while the kernel waits for more memory being available to allow the virtual address being written. This is kept as a task in the run queue until the memory is available and therefore load increases.
Typically, the linux OOM killer will start to ask eventually, freeing some memory to keep the system running. So far, OOM killer on my machine is rarely triggered automatically, but most of the time by me manually triggering via SysRq. The default OOM killer may sometimes have trouble doing the analysis of what to kill using the oom scores, and an alternative is to kill whichever task that triggers OOM (see /proc/sys/vm/oom_kill_allocating_task in proc(5)).

Change 415928 had a related patch set uploaded (by Zhuyifei1999; owner: Zhuyifei1999):
[pywikibot/core@master] [WIP] weblinkchecker: use shelve to persist data in disk real-time

https://gerrit.wikimedia.org/r/415928

^ The patch uses shelve for persistence, but memory is still increasing non-stop.

Linux typically...

Thank you!

From my current measurement:

  1. $ python pwb.py weblinkchecker -start:! -ns:0 on freshly booted system
  2. Python memory usage after start 200 MB
  3. Worked quite smoothly for 3 hours only increasing memory usage
  4. Python memory usage stopped on 1.1 GB and last 1 hour it was on the level of 1 GB. The whole system memory usage was cca 90 % (the other 0.9 GB from 1.9 GB RAM is used by Linux and Gnome), It sometimes came up to 99 % but quickly allocated swap space and lowered back to 90 %. If I would open Firefox browser when on 90 %, it would quickly add 20 % (and freeze the whole OS), therefore I was AFK.
  5. Finally the last 30 minutes the whole system memory usage 90 %, python memory usage 1 GB, 800 MB swap space used, the OS was fast, but the script was a little bit slower.
  6. I interrupted it by keyboard and got 37 threads openned, quickly reduced to last 7, which were killed by weblinkchecker finally.

Since the original mem_top measurement blamed Cookies, I looked into wheere they are referenced with guppy:

That would confirm the original deadlocking problem fixed :)

For collecting phase probably yes! :)

But...

I tested the -repeat with weblink_dead_days set to 0 on newly created data file (containing freshly collected links from ! to Adam Lambert) and got stuck on [[.lb]] again in the same way as before :( So there is still some issue with this in repeat phase. I'll try T185561#4018624

I captured two guppy heaps (same process, the second is captured later the the first):

The OS still reports the memory resident size is increasing, but guppy says it's decreasing... I guess core dumps is the way to go :(

With https://gerrit.wikimedia.org/r/415771 there is still no difference for -repeat. It still behaves as I described in T185561#4015457

Please give me the traceback of:
