pcntl_wait not interrupted by SIGTERM

由 限于喜欢 提交于 2019-12-10 17:26:24
问题 According to the PHP docs for pcntl_wait, The wait function suspends execution of the current process until a child has exited, or until a signal is delivered whose action is to terminate the current process or to call a signal handling function. However, when I run the following code and send SIGTERM to the parent process with kill -s SIGTERM [pid] the signal handler is only called after the child exits (i.e. I have to wait for the sleep to finish. Shouldn't pcntl_wait() be interrupted by

php添加pcntl扩展(Linux)

pcntl扩展可以支持php的多线程操作（仅限linux） 原本需要重新编译PHP的后面configrue提示加上--enable-pcntl 由于我的php是采用yum安装的，所以不能采用上面的方式 下面介绍一个php动态添加扩展的方式 phpize 1、首先看下 phpize命令 所在的目录 （ps：我的目录/usr/bin/phpize） 如果没有找到的话 执行安装 yum install php53_devel （ps：请注意自己的版本) 安装完毕后。会生成phpize命令 2、去php.net下载相应版本的php源文件 咱们以php-5.3.17 为例吧，解压后，进入相应的模块下 cd ext/pcntl #先执行phpize /usr/bin/phpize ./configure --with-php-config=/usr/bin/php-config （ps:请正确的指定php-config的目录） #编译、安装 make && make install 这时候出了一个错误 ./configure编译正常，但make出错 error: ‘PHP_FE_END’ undeclared here (not in a function) 解决方法： 源代码有错误，进入php-5.3.17目录 sed -i 's|PHP_FE_END|{NULL,NULL,NULL}|'

Call to undefined function pcntl_fork() php-fpm nginx

I'm trying to use pcntl_fork() in php-fpm but it is not available and I get: Call to undefined function pcntl_fork() Even though I've out-commented the disable_functions in the php.ini . phpinfo() shows the author and php -m also lists pcntl . If I'm executing my script from cli, it works. Is there any other option I need to enable? As MWE I've prepared a minimal docker environment at https://github.com/white-gecko/pcntl-mwe resp. docker pull whitegecko/pcntl-mwe if you run it with docker run -it --rm --name pcntl -p 8080:80 pcntl you will have the example at http://localhost:8080/ and phpinfo

Can APC improve the speed of CLI scripts when used with pcntl_fork()?

由 给你一囗甜甜゛ 提交于 2019-12-04 14:14:43
问题 APC works by storing the opcodes from PHP files in shared memory. When PHP is used with a web server (eg Apache) then the shared memory has a long life. When called from the commandline, then the APC cache is created and destroyed for each process. APC is disabled on the commadnline by default, probably due to this. I have a theory that there will be benefits from using APC if a PHP process is forked (with pcntl_fork() as presumably the same opcode cache can be used. This may only apply to
