[Users] Accessing data from reply route in failure route

by T.R. Missner

Hello, I have a need to pass info contained in a X-header within a 300 message to the failure-route or branch-route for inclusion in a new INVITE which results from the redirect. Is there a mechanism available that would allow me to do this? AVPs are not available in the reply route. Thanks, T.R.

[Users] NEW FEATURE: branch and script flags

by Bogdan-Andrei Iancu

Hi everybody, Following some discussions with Juha regarding some extension for the branch flags, we decided it is better to have a re-design of flags in openser to allow a better flexibility and extensibility without any consistency penalties. What we had so far: - message flags (or transaction flags) which are transaction persistent - pseudo-branch flags - a set of flags from the message flags were handled by TM as branch flags (saved per branch and not only per transaction). What we have now: - message flags (or transaction flags) will works as they do now, but the branch mask will be removed (rolling back as in 0.9.x versions). These flags are transaction persistent. - branch flags (NEW) are saved also in transaction, but per branch; also they will be saved in usrloc (per contact). A new set of functions were added for manipulating these flags from script. So, there flags will be registration persistent and branch persistent. - script flags (NEW) are no-message-related flags - they are only script persistent and you can strictly use them for scripting. Once you exit a top level route, they will be lost. These flags are useful and they offer an option to de-congest the message flags - many flags have no need to be saved as they just reflect some scripting status. What changes brings this: - NAT flag will become a branch flag all the time. - you can have custom flags to be saved into usrloc (via branch flags). - more flags in script (via script flags). Corresponding Functions: Message/transaction flags: setflag(flag_idx) resetflag(flag_idx) isflagset(flag_idx) Branch flags: setbflag/setbranchflag(branch_idx,flag_idx) resetbflag/resetbranchflag(branch_idx,flag_idx) isbflagset/isbranchflagset(branch_idx,flag_idx) or, the shorter format, working on the default (branch 0) flags: setbflag(flag_idx) resetbflag(flag_idx) isbflagset(flag_idx) Script flags: setsflag/setscriptflag(flag_idx) resetsflag/resetscriptflag(flag_idx) issflagset/isscriptflagset(flag_idx) Flags and Pseudo Variables Message/transaction flags $mf (decimal) , $mF (hexa) Branch flags $bf (decimal) , $bF (hexa) Script flags $sf (decimal) , $sF (hexa) Flags and routes: Message/transaction flags These flags will show up in all routes where messages related to the initial request are processed. So, they will be visible and changeable in onbranch, failure and onreply routes; the flags will be visible in all branch routes; if you change a flag in a branch route, the next branch routes will inherit the change. Branch flags There flags will show up in all routes where messages related to initial branch request are processed. So, in branch route you will see different sets of flags (as they are different branches); in onreply route yo will see the branch flags corresponding to the branch the reply belongs to; in failure route, the branch flags corresponding to the branch the winning reply belongs to will be visible. In request route, you can have multiple branches (as a result of a lookup(), enum query, append_branch(), etc) - the default branch is 0 (corresponding to the RURI); In reply routes there will be only one branch , the 0 one. In branch route the default branch is the current process branch (having index 0); In failure route, initialy there is only one branch (index 0), corresponding the the failed branch. Script flags There flags are available only in script and are reset after each top level route execution (routes internally triggered by OpenSER). They will be persistent per main route, onreply_route, branch_route, failure_route. Note they will be inherit in routes called from other routes. Example: nat flag handling .......... # 3 - the nat flag modparam("usrloc","nat_bflag",3) .......... route { .......... if (nat detected) setbflag(3); # set branch flag 3 for the branch 0 .......... if (is_method("REGISTER")) { # the branch flags (including 3) will be saved into location save("location"); exit; } else { # lookup will load the branch flag from location if (!lookup("location")) { sl_send_reply("404","Not Found"); exit; } t_on_branch("1") t_relay(); } } onbranch_route[1] { xlog("-------branch=$T_branch_idx, branch flags=$bF\n"); if (isbflagset(3)) { #current branch is marked as natted ......... } } if no parallel forking is done, you can get rid of the branch route and add instead of t_on_branch(): ........ if (isbflagset(3)) { #current branch is marked as natted ......... } ......... I will upload this description on the wiki page to be more accessible - in the mean while, any feedback (reports, better ideas, bugd) are welcome! Regards, Bogdan

[Serusers] problem with german characters with exec_msg

by Shazad

Hello ! I got an problem with the exec_msg function. When I use it to start an shell script which sends an Instant Message with german characters the Instant Message arrives to the UA with special german characters replaced with "?" symbol ... When I start the shell script manually on the shell , the error does not occur. I dont know , whether there exists special parameters for exec module or the the exec_msg function to set. Can someone tell me, hoe I can solve the problem with , that the SER doesnt replace special german characters with an "?" . Thanks ___________________________________________________________ Der frühe Vogel fängt den Wurm. Hier gelangen Sie zum neuen Yahoo! Mail: http://mail.yahoo.de

[Users] No memory left errors and Private Memory Size

by Max Gregorian

Firstly, Happy New Year to all, I am seeing quite a few of these memory errors in the openser log file: *build_contact(): No memory left*. These seem to be occurring when the UA tries to register with Openser. In the last instance I saw, this lasted almost half an hour before clearing up. So I guess what I am trying to find out really is: 1. Is this related to the Private memory size issue I remember reading about a while ago? I am using Openser 1.0.1 and so far have not messed with the default memory size settings from the sources I downloaded. The link on the Openser website about increasing Private memory seems to imply that this could be what is producing these errors. (I refer to this link - http://openser.org/dokuwiki/doku.php/troubleshooting:private-memory-size). 2. Also, if I really have to increase the private memory, I would like to know how to go about it. Since I already have openser installed and the server is already in use, do I have to wipe the server and partitions and re-install the modified Openser or is there an easier way? Can I just recompile the sources and re-install openser over the previous one and get it to overwrite the existing directory (without experiencing any problems with left over files)? 3. How much Private memory is enough to stop these errors? For example, for a system with 1GB of installed RAM should it be using say 768MB? 4. Finally, can anyone tell me the difference between *private memory* and *share memory* in this context? The only difference I am aware of is to do with, for example, shared graphics memory (e.g. for onboard graphics cards on some systems which use up some amount of installed physical RAM memory instead of their own onboard graphics memory). Is this the same thing? Sorry if some of these questions sound a bit basic but I'm coming from a Windows background. Thanks in advance.
