2020-05-25api: add new stream message conventionOle Troan1-14/+36
Instead of having to wrap dump/detail calls in control ping, send details messages in between a normal reply / request pair. As expressed in the below service statement. Example: service { rpc map_domains_gets returns map_domains_get_reply stream map_domain_details; }; define map_domains_get { u32 client_index; u32 context; u32 cursor; }; define map_domains_get_reply { u32 context; i32 retval; u32 cursor; }; To avoid blocking the main thread for too long, the replies are now sent in client message queue size chunks. The reply message returns VNET_API_ERROR_EAGAIN when there is more to read. The API handler must also include a "cursor" that is used to the next call to the get function. API handler example: REPLY_AND_DETAILS_MACRO (VL_API_MAP_DOMAINS_GET_REPLY, mm->domains, ({ send_domain_details (cursor, rp, mp->context); })); The macro starts from cursor and iterates through the pool until vl_api_process_may_suspend() returns true or the iteration reaches the end of the list. Client Example: cursor = 0 d = [] while True: rv, details = map_domains_get(cursor=cursor) d += details if rv.retval == 0 or rv.retval != -165: break cursor = rv.cursor or the convenience iterator: for x in vpp.details_iter(vpp.api.map_domains_get): pass or list(details_iter(map_domains_get)) Change-Id: Iad9f6b41b0ef886adb584c97708dd91cf552749e Type: feature Signed-off-by: Ole Troan <ot@cisco.com>

2020-02-05stats: fix state counter removalVladimir Isaev1-0/+3
Avoid using vec_del1() for directory vector to keep indexes valid all the time. There are state counters for each slave in LACP bond mode which can be dynamically created and removed. Vector index is used to access these counters. But also vec_del1() is used to remove counter from vector. This function changes the index of the last element, so after this we are unable to access ex-last element using old index. As a result it is not possible to add-del-add two interfaces to the LACP bond: DBGvpp# create bond mode lacp BondEthernet0 DBGvpp# create packet-generator interface pg1 DBGvpp# create packet-generator interface pg2 DBGvpp# bond add BondEthernet0 pg1 DBGvpp# bond add BondEthernet0 pg2 DBGvpp# bond del pg1 DBGvpp# bond del pg2 DBGvpp# bond add BondEthernet0 pg1 DBGvpp# bond add BondEthernet0 pg2 bond add: /if/lacp/1/3/partner-state is already register Type: fix Signed-off-by: Vladimir Isaev <visaev@netgate.com> Change-Id: I2c86e13905eefdef6233369cd4ab5c1b53d123bd

In the previous implementation of socket transport for PAPI, socket methods .send and .recv_into were used. But they are not guaranteed to send/receive all the data for the full message. The receive part contained a loop, but it handled only the main message, not the header. This patch replaces .send with .sendall and uses newly defined _read_fixed method.

2019-09-16api: autogenerate api trace print/endianOle Troan1-2/+2
In addition to the external vppapitrace tool, VPP itself supports dumping of API trace files. In two formats, "custom-dump" and "dump". "dump" gives a human friendly list, and "custom-dump" is meant to give a list of commands that can be fed to VAT. This patch only deals with "dump". Prior to this fix, auto-generation was only done for the basic types. This fix adds support for any type, including lists, and supports pretty-printing of enums, strings, IP addresses, MAC addresses and so on.

2019-07-16papi: use the injected logger wherever possibleVratko Polak1-18/+6
As the injected logger is already expected to be used everywhere, this is a fix. The few lines in vpp_serializer.py are not fixed, but they are not encountered in CSIT testing. Functions call_logger and return_logger have single call site each (and confusing names, as they do not log), so saved few lines by inlining them.
