Proposal
Please describe your proposal in detail. Include:
An overview of your proposal
Shumgrepper is a project to get md5sum, sha1sum and sha512sum of every file in every package in Fedora. I think I could fork the project named datagrepper, and use the project summershum to get the information of the md5sum, sha1sum and sha512sum.
The need you believe it fulfills
When this project is finished, any user can easily get md5sum, sha1sum and sha512sum of every file in every package. The data is formatted in json. So I think it is easy to use it in other projects, such as finding the relationship among some open-source projects.
Any relevant experience you have

There are some other projects, you can view my Github account.
How you intend to implement your proposal
Shumgrepper is a new project that is similar with datagrepper. So it could fork from Datagrepper. Shumgrepper is a project based on Flask, SQLAlchemy and summershum. Datagrepper is a project based on Flask, SQLAlchemy and fedmsg.
I think the view of datagrepper and shumgrepper is similar, so I think the modify for view is easy, just change the word that returned.
Summershum and shumgrepper can be connected with each other in database and Python data. For the query that has been generated, it’s okay just to return the database query from the database. As for the old data, shumgrepper should use summershum modules and datagrepper to download the packages. Then calculate md5sum, sha1sum and sha512sum of the file, return to user in json and store it in database.
I looked carefully at the code of summershum. There has been a model of database in summershum. I could use this model in shumgrepper which will make the connection between summershum and shumgrepper smooth.
A rough timeline for your progress
- 21 April - 1 May: Read the code of shumgrepper and datagrepper. (Maybe fix some small bug in passing)
- 1 May - 10 May: Make the blueprint (such as which way to use to get the connect between shumgrepper , the name of the method to use …) of the project.
- 1 May - 15 June: Code, finish the basic function of the project. (user can get json information of md5sum, sha1sum and sha512sum)
- 16 June - 25 June: Review the code , find bug and write a mid-term evaluations.
- 25 June - 30 July: Imporve the function of the project, fix the bug and enhance performance.
- 30 July - 18 August: Make some test and finish the documents of the project.
Any other details you feel we should consider
I think we should consider of the ocasion when there are a great amount of requests, and they may be in parallel.
First we should deal with concurrency conflict, for example, there is two request querying for the hash num that is not in the database, the core judge both of them need to generate new data. If the two operation done parallelly, there may cause two data which is same in the database. So we should confirm the operation is an atom operation.
Second one is performance problem, we should review the code and make it run fast, in order to deal with a great amount of request.
Have you communicated with a potential mentor? If so, who?
No.
