As you probably have noticed the git repository for sip-router is now online. It was started from ser core and tm. git urls: git://git.sip-router.org/sip-router (read only) http://git.sip-router.org/sip-router (read only, slower, git://... recomended) ssh://git.sip-router.org/sip-router (read write but account on git.sip-router.org needed) Web interface: http://git.sip-router.org/cgi-bin/gitweb.cgi Branches acl: the repository is setup so that you can write/commit only to the following branches: <your_username>/.* tmp/.* master We'll add access to more branches as needed (I've added this rules to avoid creating lots of "root" branches by mistake, e.g. git pull from a local branch without a refspec). Please create the commit messages following the git convention (start with one short line, preferably less then 50 chars summarizing the changes, then one empty line and then a more detailed description). See: http://www.kernel.org/pub/software/scm/git/docs/user-manual.html#creating-g… http://www.tpope.net/node/106 Quick git introduction: # clone the repo into the sip-router directory git clone git://git.sip-router.org/sip-router cd sip-router git branch -a # show all branches # create a local branch based on origin/andrei/mod_f_params git checkout --track -b my_branch origin/andrei/mod_f_params git log # see commit log git log --pretty=oneline # only the first line from each commit vim Makefile.defs git add Makefile.defs git commit # or git commmit -a to skip the add step and commit all # changed files # push changes back (note you need ssh access for this) # note: the next command will fail, unless your username is andrei :-) # publish changes on the local "my_branc" to the remote # andrei/mod_f_params git push origin my_branch:andrei/mod_f_params # or push them into the master branch if you are sure about them git push origin my_branch:master For more info about git try: http://git.or.cz/gitwiki/GitDocumentation and if you want to know how it works: http://eagain.net/articles/git-for-computer-scientists/ (highly recommended) CVS access: CVS_SERVER="git cvsserver" cvs \ -d :ext:andrei@git.sip-router.org/sip-router co master (instead of master you can use any other branch name that doesn't include a '/') The initial checkout takes a while, but after that cvs update seems fast enough. SVN access: unfortunately we do not have it. It looks like the git svnserver is in the project stage (there is some python code but not runnable yet). There is a way around it, but it would be quite complex to setup: a git to svn gateway and then svn to git imports. Other repositories on git.sip-router.org: ser - entire ser updated from cvs ser_core - only ser_core, automatically updated from cvs, read-only test - test repository, contains an early sip-router version, it has the same access rules as sip-router (if you have something you want to test, please use it rather then trying directly on sip-router). Special thanks go to Jan, who not only did setup git.sip-router.org (including automatic cvs sync for some of the repos), but he's also hosting it on one of his private machines. Andrei

The sip-router.cfg will look like: route{ ... dns_prefetch("uri", ROUTE_DNS_OK); # end of script } route[ROUTE_DNS_OK]{ if (dns_error){ ... } # continue normal processing # the uri was resolved and is in the dns cache ... t_relay() ... } However don't expect something quickly as everybody is quite busy and we would still need to write a dns resolver process pool (time consuming). Note that this is not the "final" async. solution since it's not transparent for the script writer (scripts would have to be written in a special way), works only with tm and it's also a little inefficient for dns usage. In the long term we will have completely transparent async. support for dns and maybe db lookups (though it's controversial if we really need it for normal db lookups). This will take much longer and will require among other things reviewing all the global variable use (most of the global variables will either need to be registered or allocated in some known special place). If Miklos doesn't beat me to it, I'll probably start working on it only after the core merging is complete. > > Can this also be used for DNS lookups and TCP/TLS connection setup? Yes for DNS (see above) and in general for any route-level async processing involving tm (e.g. lookup some part of the message in a slow DB and execute automatically another route when the DB responds). It cannot be used for TCP/TLS, but it's not needed anyway. In ser TCP connection setup and TCP send is already asynchronous, at least if you have tcp_buf_write=yes in ser.cfg (I agree it's not a very well chosen name :-)). TLS does not support it yet, so if you use TLS you should not set this option (that's why it's not yet the default). TLS support for it requires non-trivial changes in the tcp core and it will probably come after the merge (it's started already but far from finished). (BTW: most of the core new options documentation in ser can be found in NEWS) Andrei > > Further, also for Kamailio cooperation better documentation would be > needed.

append_branch() inside modules

by Daniel-Constantin Mierla

Hello, there are couple of modules that change the R-URI and automatically call append_branch() if the execution takes place in failure_route, other modules don't. Perhaps we should get to a coherent behavior, if not for existing code, then for the future. Probably the most flexible, better in my opinion, is to let script writer to call append_branch() in config -- once done, it is no way now to revert. A new branch should be automatically done only if it is a specific operation, e.g., location lookup with more than one record. What do you think? Cheers, Daniel PS. this blending of the ser-kamailio sources gives me ideas to do some cleanup as I review the code ... especially after midnight ... -- Daniel-Constantin Mierla http://www.asipto.com

static buffers

by Daniel-Constantin Mierla

Hello, There seem to be many places where static buffers are used for building strings. It is clear they are used just for usage inside some functions, with no need to keep the value for usage somewhere else. Would defining a global static buffer to be used for such cases make sense? The access to the pointer and size can be given via functions. There could be couple of such buffers to be used in the cases one function need concurrent access to more than one ... opinions? It will reduce memory space reserved and used... Cheers, Daniel -- Daniel-Constantin Mierla http://www.asipto.com

git version >= 1.5.6

by Andrei Pelinescu-Onciul

It's highly recommended to use git versions >= 1.5.6 (e.g. 1.5.6.1, 1.6.0.4 a.s.o) if you use/do git merge. Older versions do not support the merge.log options or git merge --log and _will_ not generate merge summaries in the merge commit messages (which are very nice to have). If you have an older version and you don't want to upgrade try setting merge.summary (git config merge.summary true). Andrei
