2020-03-06vcl: refactor vls to minimize lock usageFlorin Coras2-105/+418
Type: refactor - per vls worker private pool of sessions - deep copy of vls worker data structures on fork - maintain a global, i.e., heap allocated, and lock protected pool of elements that track sessions that are shared between workers (due to forking).

2020-02-25svm: refactor fifoFlorin Coras1-2/+4
Type: refactor Switch from a wrapped byte space to a "continuous" one wherein fifo chunks are appended to the fifo as more data is enqueued and chunks are removed as data is dequeued. The fifo is still subject to a maximum size, i.e., maximum number of bytes that can be enqueued, so the max number of chunks associated to the fifo is also constrained. When enqueueing data, which must fit within the available free space, if not enough "supporting" chunk memory is available, the fifo asks the fifo segment for enough chunk memory to ensure that the write can succeed. To avoid allocating large amounts of small chunks due to small writes, if possible, the size of the chunks requested is lower capped by min_alloc. When dequeuing data, all the chunks that have been completely drained, i.e., head moved beyond the chunks’ end bytes, are unlinked from the fifo and returned to the fifo segment. The one exception to this is the last chunk which is never unlinked. Change-Id: I98c1dbd9135fb79650365c7e40c29238b96cd4ee Signed-off-by: Florin Coras <fcoras@cisco.com>

2019-12-30vcl: hold errno when calling LDBGhanlin1-1/+5
Type: fix Call trace of LDBG: LDBG->clib_warning->_clib_error->dispatch_message->os_puts->writev However, writev will hijacked by LDP, and then execute following code: if ((errno = -ldp_init ())) return -1; Now, errno will be set. Because we always call LDBG just before return from ldp_accept4, listen, and etc. So errno will be overwritted after LDBG called.

2019-12-04build: fix make test with distributed srcDave Wallace1-0/+815
This patch addresses the functionality that is missing for distributed make test source files. In addition it extends the concept of colocating test source code with functional source code (eg. src/vcl/test). It also cleans up deficiencies in the make test makefiles. NOTE: Due to the way sphinx document tools work, all test, all of the make test python code is gathered using soft links into the directory: .../build-root/build-test/src Change summary: - Remove 'make test' help details from main makefile help output to reduce clutter and redundant help output - Move all generated build output to .../build-root/build-test - Move test_vcl.py as first usecase for distributed core feature make test code - Add test-wipe-all target and fix wipe targets to remove all generated files - Fix 'make test-doc' to generate module documentation for all source files - Remove unused targets in test/doc/Makefile - Fix 'make test-shell' - Fix test/ext Makefile to not generate bogus output Type: fix Fixes: a43c93f8554ad7418e31be3791b3fb71232f60ac Change-Id: Icc2ddb81d474081c3ede4548ecd7a0624651f62d Signed-off-by: Dave Wallace <dwallacelf@gmail.com>
