restriction

问题 I knew that I can add a Valve in context.xml in tomcat server to allow or deny some IP address : <Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="127\.0\.0\.1" denyStatus="403" /> Except above configuration, Are there any other method that I can config IP restriction? For example, can I use text file or database to store IP addresses for IP restriction propose? Thank you very much!!! 回答1: You can dynamically register Tomcat's Remote Address Filter. http://tomcat.apache.org

问题 I have populated my ontology with data defining among others Hour. Now, I want to make a restriction on that specific datatype (hour) which is defined as int and has values from 0-23. The restriction would be set on the division of the hour according to day and night for example (hour min 6 int) and (hour max 17 int) for the day and that defined as object Property isDay, but the problem is the inferences does not happen. Thank you in advance, Eliot 回答1: You can create a :DayEvent class as

问题 I have migrated a site from one host to another, on this site there is a crm working or at least used to work. Since the migration was done the link to the crm responded with error500-internal server error and I contacted the host in order to check it. They said they fixed it and now it shows me the following PHP Warning: include_once(): open_basedir restriction in effect. File(/var/www/vhosts/mysite.com/httpdocs/crm/includes/adodbtime/adodb-time.inc.php) is not within the allowed path(s): (G

问题 I want to restric user from entering any special character or number into edit text, but programmatically it should allow. I know I can make inputType="text" but it deals only with the softkeyboard. I think it can be achived with TextWatcher, but I am not able to gel evrything. Can anyone help ? 回答1: editTextView.setInputType(InputType.TYPE_TEXT_VARIATION_NORMAL); There are many other types of inputs available for Password, Email address etc. Please see This API Link Thanks :) 回答2: You can

问题 Is it possible to create an environment to safely run arbitrary Python scripts under Linux? Those scripts are supposed to be received from untrusted people and may be too large to check them manually. A very brute-force solution is to create a virtual machine and restore its initial state after every launch of an untrusted script. (Too expensive.) I wonder if it's possible to restrict Python from accessing the file system and interacting with other programs and so on. 回答1: Consider using a

问题 Note: This is basically the same question as another one I've posted on Stackoverflow yesterday. However, I figured that I used a poor example in that question that didn't quite boil it down to the essence of what I had in mind. As all replies to that original post refer to that first question I thought it might be a better idea to put the new example in a separate question — no duplication intended. Model Game Characters That Can Move Let's define an enum of directions for use in a simple

问题 I have problem with CROSS APPLY with parametrised table valued function. Here is simplified pseudo code example: SELECT * FROM ( SELECT lor.* FROM LOT_OF_ROWS_TABLE lor WHERE ... ) AS lor CROSS APPLY dbo.HeavyTableValuedFunction(lor.ID) AS htvf INNER JOIN ANOTHER_TABLE AS at ON lor.ID = at.ID WHERE ... Inner select on table LOT_OF_ROWS_TABLE is returning many rows. Joining tables LOT_OF_ROWS_TABLE and ANOTHER_TABLE returns only one or few rows. Table valued function is very time consuming and

问题 Can anyone help me to add a restriction to this schema file (for OwnerEnglishName)? I know how to do it with a simpletype, while in a complextype I don't know how to do it. Can anyone help? Thanks a lot. Original XML: <PACIDemoSignedDoc PaciSDocID="HouseOwnerSignedEndorsement"> <OwnerEnglishName OENID="Name"></OwnerEnglishName> </PACIDemoSignedDoc> Schema (without restriction): <?xml version="1.0" encoding="utf-8"?> <xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified"

问题 Python's threading documentation states: Other than in the main module, an import should not have the side effect of spawning a new thread and then waiting for that thread in any way. Failing to abide by this restriction can lead to a deadlock if the spawned thread directly or indirectly attempts to import a module. I'm looking for example code that demonstrates this restriction. 回答1: I tried this, a module that spawns a thread whose target tries to import sys : from threading import Thread

问题 In a MySQL table, naming a column, can I use spaces uppercase letters UTF8 characters What other rules shall I follow? ( MySQL5 ) 回答1: Yes, Yes, and Yes. I like underscores between field names and no uppercase, but I don't want to start a flame war. Another good reason to not use special characters in column names is you, or others are eventually going to have to type that over and over in your application. I'd stick to the standard english alphabet. Good column names: account_id user_id
