            What we can see in the html table, is that the first row holds a cell for every hierarchy level which is represented as a column. This means it has to be generated a row with all elements from the highest till the deepest hierarchy level. The element on the deepest hierarchy level is the one without further descendants. To get these we can use this xpath expression

            How do you fix a memory leak within Django tests?
            Asked 2021-Mar-23 at 13:01

            Recently I started having some problems with Django (3.1) tests, which I finally tracked down to some kind of memory leak. I normally run my suite (roughly 4000 tests at the moment) with --parallel=4 which results in a high memory watermark of roughly 3GB (starting from 500MB or so). For auditing purposes, though, I occasionally run it with --parallel=1 - when I do this, the memory usage keeps increasing, ending up over the VM's allocated 6GB.

            I spent some time looking at the data and it became clear that the culprit is, somehow, Webtest - more specifically, its response.html and response.forms: each call during the test case might allocate a few MBs (two or three, generally) which don't get released at the end of the test method and, more importantly, not even at the end of the TestCase.

            I've tried everything I could think of - gc.collect() with gc.DEBUG_LEAK shows me a whole lot of collectable items, but it frees no memory at all; using delattr() on various TestCase and TestResponse attributes and so on resulted in no change at all, etc.

            I'm quite literally at my wits' end, so any pointer to solve this (beside editing the thousand or so tests which use WebTest responses, which is really not feasible) would be very much appreciated.

            (please note that I also tried using guppy and tracemalloc and memory_profiler but neither gave me any kind of actionable information.)

            Update

            I found that one of our EC2 testing instances isn't affected by the problem, so I spent some more time trying to figure this out. Initially, I tried to find the "sensible" potential causes - for instance, the cached template loader, which was enabled on my local VM and disabled on the EC2 instance - without success. Then I went all in: I replicated the EC2 virtualenv (with pip freeze) and the settings (copying the dotenv), and checked out the same commit where the tests were running normally on the EC2.

            Et voilà! THE MEMORY LEAK IS STILL THERE!

            Now, I'm officially giving up and will use --parallel=2 for future tests until some absolute guru can point me in the right directions.

            Second update

            And now the memory leak is there even with --parallel=2. I guess that's somehow better, since it looks increasingly like it's a system problem rather than an application problem. Doesn't solve it but at least I know it's not my fault.

            Third update

            Thanks to Tim Boddy's reply to this question I tried using chap to figure out what's making memory grow. Unfortunately I can't "read" the results properly but it looks like some non-python library is actually causing the problem. So, this is what I've seen analyzing the core after a few minutes running the tests that I know cause the leak:

            Guppy color change problem with if/else. how to solve it?
            Asked 2021-Feb-27 at 01:43

            I have a guppy strategy which should enter either long (when guppy becomes green under certain conditions) or short (when guppy becomes red under certain conditions). To determine the colour in pine script I used if/else. What the problem is? I'm getting the third type of colour when none of two conditions are met (let's say grey colour) and in the situation where, for example, i get red1=>grey=>red2 My strategy sends signal to close previous trade when red2 occurs and open new one with the same direction. In my strategy grey is not a signal for entering/exiting the position, so i want to make the current 'grey' to be coloured the same way the previous segment was colored until fully opposite condition was met. I tried else na, but those intermediate condition still gives me wrong signals, i also tried to put plotcolor=plotcolor[1] in 'else' but this type of command cannot be placed in pine script. Can please anyone help me to solve this?

            Assume they are in sorted order first. Then return as soon as you find ones that aren't. No need to keep checking upon encountering the first failure. This does a simple verification and does not print any information. It returns true if sorted in ascending order and false otherwise. It also presumes the id number is an int.

            When you're opening a file in Python, by default you're opening it in Text-mode. That means that the binary data is decoded based on operating system defaults or explicitly given codecs.

            Like all data, textual data is represented by bytes in your computer. Most of the English alphabet is representable in a single byte, e.g. the letter "A" is usually translated to the number 65, or in binary: 01000001. This encoding (ASCII) is good enough for many cases, but when you want to write text in languages like Romanian, it is already not enough, because the characters ă, ţ, etc. are not part of ASCII.

            For a while, people used different encodings per language (group), e.g. the Latin-x group of encodings (ISO-8859-x) for languages based on the latin alphabet, and other encodings for other (especially CJK) languages.

            If you want to represent some Asian languages, or several different languages, you'll need encodings that encode one character to multiple bytes. That can either be a fixed number (e.g. in UTF-32 and UTF-16) or a variable number, like in the most common "popular" encoding today, UTF-8.

            Back to Python: The Python string interface promises many properties, among them random access in O(1) complexity, meaning you can get the 1245th character even from a very long string very quickly. This clashes with the compact UTF-8 encoding: Because one "character" (really: one unicode codepoint) is sometimes one and sometimes several bytes long, Python couldn't just jump to the memory address start_of_string + length_of_one_character * offset, as the length_of_one_character varies in UTF-8. Python therefore needs to use a fixed-bytelength encoding.

            For optimization reasons it doesn't always use UCS-4 (~UTF-32), because that will waste lots of space when the text is ASCII-only. Instead, Python dynamically chooses either Latin-1, UCS-2, or UCS-4 to store strings internally.

            To bring everything together with an example:

            Say you want to store the string "soluţie" in memory, from a file encoded as UTF-8. Since the letter ţ needs two bytes to be represented, Python chooses UCS-2:

            Vulnerabilities

            Multiple static code injection vulnerabilities in error.php in GuppY 4.5.16 and earlier allow remote attackers to inject arbitrary PHP code into a .inc file in the data/ directory via (1) a REMOTE_ADDR cookie or (2) a cookie specifying an element of the msg array with an error number in the first dimension and 0 in the second dimension, as demonstrated by msg[999][0].
            Directory traversal vulnerability in error.php in GuppY 4.6.3, 4.5.16, and earlier allows remote attackers to include and execute arbitrary local files via a .. (dot dot) in the id parameter. NOTE: this can be leveraged to bypass authentication and upload arbitrary files by including admin/inc/upload.inc and specifying certain multipart/form-data input for admin/inc/upload.inc.
            Multiple cross-site scripting (XSS) vulnerabilities in GuppY before 4.6.28 allow remote attackers to inject arbitrary web script or HTML via the (1) "an" parameter to agenda.php or (2) cat parameter to mobile/thread.php.

            Install guppy

            To use Guppy, you'll first need to have a modern version of Node (a Javascript runtime) installed. Download Node. The "Current" version is recommended over LTS due to a bug in NPM 5.6.0 that can corrupt dependencies. Once Node is installed, you can download Guppy. Double-click the downloaded executable to open Guppy. Mac users may need to right-click and select "Open" if MacOS complains about the fact that this was downloaded from the internet.
