问题 I have a table to make temporary id`s . When i delete all of the rows of my table , auto increment value for this table will reset to 0 . but i don't want to reset the auto increment.

How to detect cold boot versus warm boot on an ARM processor?

由 不问归期 提交于 2019-12-22 04:43:15
问题 I'm looking for a way to determine whether an ARM processor is booting from a cold boot (i.e. initial power-on) versus a warm boot (i.e. reset assertion without actual power loss). Specifically I'm using an ARM968 core, will be making the determination using C or assembly, and I will use the determination so certain operations only run on the initial power-on and not on subsequent resets. In previous projects I've leveraged external circuitry (e.g. FPGA) to detect the different boot scenarios

Sqlite: How do I reset all database tables?

由 让人想犯罪 __ 提交于 2019-12-22 04:35:10
问题 I want a debug function to do this, but I'm unaware of whether one already exists. Going through and using 'drop table' for each of my tables will be a pain. Help appreciated. 回答1: Since the database is just one file, you can indeed just erase it. If you want something more automatic, you can use the following to do it all programmatically: Recover your schema: SELECT group_concat(sql,';') FROM sqlite_master; Disconnect from the database Delete the database file Create your schema again with

nginx php fastcgi Connection reset by peer的原因及解决办法

由 穿精又带淫゛_ 提交于 2019-12-21 07:24:23
Connection reset by peer 这个错误是在nginx的错误日志中发现的，为了更全面的掌握nginx运行的异常，强烈建议在nginx的全局配置中增加 error_log logs/error.log notice; 这样，就可以记录nginx的详细异常信息。 nginx的错误日志中会出现Connection reset by peer) while reading response header from upstream, client: 1.1.1.1, server: 102.local, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000 后来反复检查，发现这是因为php运行较慢，并超出php-fpm.conf的request_terminate_timeout设置的秒数。 request_terminate_timeout用于设置当某个php脚本运行最长时间，若超出php-fpm进程管理器强行中止当前程序，并关闭fastcgi和nginx的网络连接，然后nginx中就会出现Connection reset by peer的错误了。 也就是说，产生这个错误的原因是： php 程序的运行时间超出request_terminate_timeout设置的值。 在php-fpm环境下

由 我们两清 提交于 2019-12-21 02:41:37
问题 I've integrated the zxing library into my app but part of my requirement is to be able to continually scan QR codes. I've accomplished this to a certain degree by dismissing and re-presenting the zxing widget but it appears to be too slow for my client. Is there another way to reset the widget to start scanning again? 回答1: You will have to tamper with the ZXing library, fortunately it's not hard. Add the following method to the ZXingWidgetController In ZXingWidgetController.h - (void)reset;

Perform Javascript action after reset button handles click

由 走远了吗. 提交于 2019-12-21 01:57:44
问题 How do I perform an action immediately after an <input type="reset"/> has already reset the form elements? 回答1: Forms have a reset event that you can listen for. <script> function resetHandler() { // code } </script> <form ... onreset="resetHandler();"> </form> Of course, it's bad practice to add javascript handlers this way, so you'd want to use .addEventListener/.attachEvent or jQuery.bind() , but you get the idea. 回答2: Try : <input type="reset" onclick="return resetForm();"/> function
