2020-02-06vlib: add plugin override supportDave Barach1-0/+3
Allow a plugin to override (suppress loading of) other plugins. This mechanism allows a developer to prevent specific plugins from being loaded. To do so, provide an "overrides" list in the plugin definition: VLIB_PLUGIN_REGISTER () = { <snip> .overrides = "avf_plugin.so,ioam_plugin.so,dpdk_plugin.so", }; or some such. Simply list the plugins in question as shown above. The .overrides structure member is limited to 256 octets. The named .elf section mechanism used to discover the vlib_plugin_registration_t's precludes the use of a variable-length array of strings. Use the vlib log to eliminate plugin and built-in vat plugin loader console spew. Added vlib_log_register_class_rate_limit(...) to allow procedural configuration of the log rate-limit. We *never* want to rate-limit plugin loader messages. Type: feature Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I0a9327b8cf5508482f057342783252112cb44170
2019-07-08api: Implement log_dump/log_detailsPaul Vinciguerra1-0/+54
- Replaces the need to screen scrape "show log". - Adds an api to return the system time. When running over a socket, the api client may have different time than the vpp host. expected use: vpp_time_before_command = self.vapi.show_vpe_system_time_ticks().vpe_system_time_ticks <run some commands> log_output = self.vapi.log_dump(start_timestamp=vpp_time_before_command) Depends-on: https://gerrit.fd.io/r/20484 Depends-on: https://gerrit.fd.io/r/#/c/19581/ ============================================================================== TestVpeApi ============================================================================== log_details(_0=838, context=3, timestamp_ticks=2.4954863503546518e+48, level=<vl_api_log_level_t.VPE_API_LOG_LEVEL_WARNING: 4>, timestamp=u'2019/07/04 20:35:41:281', msg_class=u'buffer', message=u'vlib_physmem_shared_map_create: clib_mem_create_hugetlb_fd: open: No such file or directory\n\n') log_details(_0=838, context=3, timestamp_ticks=1.6101902879480125e+159, level=<vl_api_log_level_t.VPE_API_LOG_LEVEL_WARNING: 4>, timestamp=u'2019/07/04 20:35:41:281', msg_class=u'buffer', message=u'falling back to non-hugepage backed buffer pool') test_log_dump_default (test_vpe_api.TestVpeApi) OK log_details(_0=838, context=13, timestamp_ticks=2.4954863503546518e+48, level=<vl_api_log_level_t.VPE_API_LOG_LEVEL_WARNING: 4>, timestamp=u'2019/07/04 20:35:41:281', msg_class=u'buffer', message=u'vlib_physmem_shared_map_create: clib_mem_create_hugetlb_fd: open: No such file or directory\n\n') log_details(_0=838, context=13, timestamp_ticks=1.6101902879480125e+159, level=<vl_api_log_level_t.VPE_API_LOG_LEVEL_WARNING: 4>, timestamp=u'2019/07/04 20:35:41:281', msg_class=u'buffer', message=u'falling back to non-hugepage backed buffer pool') test_log_dump_timestamp_0 (test_vpe_api.TestVpeApi) OK test_log_dump_timestamp_future (test_vpe_api.TestVpeApi) SKIP test_show_vpe_system_time_ticks (test_vpe_api.TestVpeApi) SKIP ============================================================================== TEST RESULTS: Scheduled tests: 4 Executed tests: 4 Passed tests: 2 Skipped tests: 2 ============================================================================== Test run was successful Type: feature Change-Id: I893fc0a65f39749d2091093c2c604659aadd8447 Signed-off-by: Paul Vinciguerra <pvinci@vinciconsulting.com>
