version control - UCM Clear Case: Hiereachy of streams in one project vs multiple projects -

-

We have a project and otherwise adding a new piece of functionality to a stable codebase, without fixing a big change. This scheme is making intermediate construction and testing of new facility for different time (maybe one month) and the facility is ending and merged the code of new facility in the main branch in the quality admissible.

The question below is better in case of a clear case of two scenarios:

  1. A new project based on the baseline in the existing project integration stream With the intermediate distribution for the integration of the developing new project, the construction of this new project in a separate project and the integration from the stream created. And ultimately delivers changes to the new project integration stream for the main project (aka or dev).

  2. Using the hierarchy of streams in the main project: Child stream of integration stream (it is called template_in) in main project and a child stream of temp_iit (it is called temp_adv ). Develops a new feature in Temp_dev, from temp_int and temp_int with periodic distribution, and then provides new functionality from temp_int to the main integration stream.

The question is whether you need to create or create a new project Sub-section is a classical one.

In my opinion, both options are quite similar.

The only important difference is the base baseline, which you will be able to choose during the new creation, for this special development effort, Section:

  • For sub-section, you Only will be able to select the base line produced on the original stream.
  • A new project for the mainstream, you will be able to choose any of the baseline as you wish.

In addition to:

  • A new project provides a new location to isolate several streams in a consistent container but if you have new feature development If there is a need to include some small development of the static code made, the quote will be in order.
  • After the development is over, a sub-stream end allows the client to visualize clearly: Distributed original stream will be a natural operation for the merger. In addition, it is possible to keep it up to date in your development stream from the periodic rebase original stream.

So if you have only one stream with clear delivery, the sub-stream option is sufficient.
If you are getting more complex than ever before, then a good project is good.

MySql variables and php -

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
