abort

When abort() is preferred over exit()?

I know the differences between the two . One notable thing is that abort() sends SIGABRT signal, so it may be relevant when your software relies on them. But for a typical application exit() seems to be more safe version of abort()...? Are there any other concerns to use abort() instead of exit()? Using abort will dump core, if the user has core dumps enabled. So as a rule of thumb, I'd use abort if you're so unsure about what's gone wrong that the only way to get useful information about it is by analysing a core dump. If you can safely exit from any given point, and don't need the core dump,

Readfile reads 0 bytes from large file?

痴心易碎 提交于 2019-12-02 09:55:58
I'm trying to send a large file through readfile() . However, nothing is sent to the browser and readfile() returns 0 ( not false !). The file I'm trying to send is 4GiB of size and readable by PHP. I am setting set_time_limit(0) to allow a lengthy download process. I have tried to send the file in a while-loop contraption with fread() in 4K chunks and echo , but that aborts randomly (without error) after 500 - 2500 MiB downloaded and never manages to complete the download. The following test code $f = '/var/www/tmp/largefile.dat'; var_dump(file_exists($f)); var_dump(is_readable($f)); var_dump

By starting from scratch and adding bits of code until I find the error I have narrowed the problem down to the code below. I have included the whole function but can provide more code if necessary.

PHP doesn't detect connection abort at all

I have read and deeply understood these: http://www.php.net/manual/en/features.connection-handling.php http://www.php.net/manual/en/function.register-shutdown-function.php However, I have tested both PHP 5.1.6 and 5.3 and things DON'T work as described there. What I observe is: connection_status() always return true, even after the client has closed the connection. execution of the script keeps going on after the client has closed the connection, even though ignore_user_abort is 0 a function registered with register_shutdown_function() is not run until the script reaches ends. The script is

xmlHttpRequest abort() method does not close the connection in Internet Explorer

I have multiple xmlHttpRequest on my page, and I am attempting to call the abort() method on them all. Works great in FF. IE, on the other hand does not do a darn thing. The connections do not close, and I am unable to navigate to another page until the requests complete. What is this? Why doesn't IE close the connections when abort() is called? I've almost never gotten abort to work in IE. I'm tired and can't remember why - something about not being able to abort until you're in readyState 4 (or maybe that it changed to readyState 4 when it aborts?). Either way, Ajaxian has a work around in

释放上个ajax请求

var ajax = { abort: function () {} //定义一个空的方法, 是为了下面ajax.abort()不报错 }; setInterval(function () { ajax.abort(); //每次提交前, 先放弃上一次ajax的提交, 这样就不会同时有多个ajax正在请求, 卡死浏览器 ajax = $.ajax({ }); }, 1000); 来源: https://www.cnblogs.com/liangmm/p/11677848.html

python import seems to behave differently in mercurial_keyring.py file

我们两清 提交于 2019-12-01 05:44:50
A bizarre import error is preventing me from installing a mercurial extension. I'm trying to get the mercurial_keyring extension running so that I don't have to type in my user name and password every time I use mercurial for a project. I'm using Python 2.7.1. I installed mercurial with the binary provided at https://www.mercurial-scm.org/ . I installed keyring and mercurial_keyring with pip . I first tried to add the extension by adding this to ~/.hgrc : [extensions] ... mercurial_keyring = as indicated in the installation instructions here . However, I got the following error: *** failed to
