This enables the reuse of process creation functions.
|
|
|
|
|
|
The process abstraction has changed to:
setup(task, process)
start(task, process_data)
prefork(task, process, mp)
The prefork() occurs in the main process right before fork.
The file src/nxt_main_process.c is completely free of process
specific logic.
The creation of a process now supports a PROCESS_CREATED state. The
The setup() function of each process can set its state to either
created or ready. If created, a MSG_PROCESS_CREATED is sent to main
process, where external setup can be done (required for rootfs under
container).
The core processes (discovery, controller and router) doesn't need
external setup, then they all proceeds to their start() function
straight away.
In the case of applications, the load of the module happens at the
process setup() time and The module's init() function has changed
to be the start() of the process.
The module API has changed to:
setup(task, process, conf)
start(task, data)
As a direct benefit of the PROCESS_CREATED message, the clone(2) of
processes using pid namespaces now doesn't need to create a pipe
to make the child block until parent setup uid/gid mappings nor it
needs to receive the child pid.

This closes #386 on GitHub.

This is required to avoid include cycles, as some nxt_clone_* functions
depend on the credential structures, but nxt_process depends on clone
structures.

- Introduced nxt_runtime_process_port_create().
- Moved nxt_process_use() into nxt_process.c from nxt_runtime.c.
- Renamed nxt_runtime_process_remove_pid() as nxt_runtime_process_remove().
- Some public functions transformed to static.
This closes #327 issue on GitHub.

Library now used in all language modules.
Old 'nxt_app_*' code removed.
See src/test/nxt_unit_app_test.c for usage sample.

This and previous commit close #131 issue on GitHub.
|
|
The bug had appeared in 5cc5002a788e when process type has been
converted to bitmask. This commit reverts the type back to a number.
This commit is related to #131 issue on GitHub.

Finalizing Python interpreter.
This closes #65 issue on GitHub.

|
This helps to decouple process removal from port memory pool cleanups.
|
|
Use counter helps to simplify logic around port and application free.
Port 'post' function introduced to simplify post execution of particular
function to original port engine's thread.
Write message queue is protected by mutex which makes port write operation
thread safe.

Now configuration survives server reloads.

A pid file name can be relative.
The default pid file name is "nginext.pid".
|
|
A prefix is prepended to all relative names at configure stage.
There is no prefix by default.
A log file name can be relative.
The default log file name is "nginext.log".

Configuration and building example:
./configure
./configure python
./configure php
./configure go
make all
or
./configure
make nginext
./configure python
make python
./configure php
make php
./configure go
make go
Modules configuration options and building examples:
./configure python --module=python2 --config=python2.7-config
make python2
./configure php --module=php7 --config=php7.0-config
--lib-path=/usr/local/php7.0
make php7
./configure go --go=go1.6 --go-path=${HOME}/go1.6
make go1.6

Application process start request DATA message from router to master.
Master notifies router via NEW_PORT message after worker process become ready.
|
|
Now controller serializes all reconfiguration requests
and waits for result from router.
|
|
New port message type introduced NXT_PORT_MSG_REMOVE_PID. Default handler
removes process description from nxt_runtime_t with all ports, incoming and
outgoing mmaps etc.
|
|
Usage on the router side:
nxt_app_wmsg_t wmsg;
nxt_app_parse_ctx_t parse_ctx;
nxt_app_http_req_init(task, &parse_ctx);
/* parse incoming request data */
if (nxt_app_http_req_parse(task, &parse_ctx, buf) == NXT_DONE) {
/* choose app */
nxt_app = nxt_select_app(... &parse_ctx.r ...);
/* find port */
wmsg.port = nxt_get_app_port(... nxt_app ...);
wmsg.buf = &wmsg.write;
/* fill write message buffer in shared mem */
nxt_app->prepare_msg(task, &parse_ctx.r, &wmsg);
/* send message to app for processing */
nxt_port_socket_write(task, wmsg.port, NXT_PORT_MSG_DATA,
-1, 0, 0, wmsg.write);
}
|
|
|
|
|
|
|
|
|
|
Usage:
b = nxt_port_mmap_get_buf(task, port, size);
b->mem.free = nxt_cpymem(b->mem.free, data, size);
nxt_port_socket_write(task, port, NXT_PORT_MSG_DATA, -1, 0, b);

The cycle has been renamed to the runtime.
