Is there a Git Server Side Hook to put quota on repository sizes? -

-

i searched around , found related topics, related limiting file sizes or concerns there quotas.

i built git server gitolite place students share course projects. functions under 1 username on server, git, wild card repositories "projects/creator/[a-za-z0-9].*". repositories have writers , readers defined user can modify can write , read repository.

ssh key files implemented user can create repository by:

git clone git@servername.edu:projects/bob/project1 git clone git@xervername.edu:projects/bob/someotherproj

and on. "bob" folder created first time git clone (it's username).

my issue that, being students, there abuse , need limit size of "bob" folder. disk quotas don't work because folders , files owned git, , that's limited.

i can re-engineer serve projects linux home folders , able use disk quotas, however, i'd rather not have re-engineer server have working.

essentially, looking hook did rough shell script:

foldersize=`du -s $gitpath/projects/$username` if [ $foldersize > 250000 ];      echo "quota exceeded"      exit 1 fi

i understand there server side hooks can written, wanted see if wheel created before started carving out. so, hooks limit repository size?

the git pre-receive hook used implement quotas. githooks(5) man page:

this hook invoked git-receive-pack on remote repository, happens when git push done on local repository. before starting update refs on remote repository, pre-receive hook invoked. exit status determines success or failure of update.

so put quota checking logic in script , allow or reject incoming update depending on result. job perform quota management; there number of ways this, simplest being relying on filesystem's support user quotas.

you use du example, although repositories grow in size impose substantial delay (and i/o burden) each update. caching results script amount of time out, although trade-off here exceed quota if push update before cache has expired.

depending on how storage organized, per-directory quotas git repositories (if storage comes supports this, enterprise fileservers), or using lvm volume per repository (as suggested here).

despite suggestions contrary, implementing quotas remote repository common. git-hosting services limit disk storage , reject updates once hit limit.

on website user have 1 group. , user can change group. it's made user.groups.clear() and user.groups.add(new_group) but it's not efficient, because there 2 sql query: delete, insert. how can change group update query? user , group related each other using manytomanyfield . means intersection table exists relating both entities, , if don't specify model map (using through attribute) django creates 1 you. looking @ sources django.contrib.auth.models see that's case. fortunatly, can access intermediary model using through attribute of manager (in case, user.groups.through ). can use regular model. example: >>> alice = user.objects.create_user('alice', 'alice@example.com', 'alicepw') >>> employee = group.objects.create(name='employee') >>> manager = group.objects.create(name='manager') >>> alice.groups.add(employee) >>> alice.groups.all() [<group: employee...

i need set custom soap header attribute on jax-ws generated webservice client. case webservice calls must go through proxy server requiring specific token (recieved web request header) present in soap request header. e.g.: 1 carserviceservice service = null; 2 service = new carserviceservice(new url(url), new qname(qname); 3 carserviceendpoint port = service.getcarserviceport(); it seems in line 3 wsdl retrieved , call fails due missing security token. 1 point direction on how done? a detailed example has been mentioned here: creating , deploying jax-ws web service on tomcat 6 this article shows how create , use security token .
