2020-08-20Moved isolation related code to "nxt_isolation.c".Tiago Natel de Moura1-581/+4
2020-08-11Moving file descriptor blocking to libunit.Max Romanov1-6/+0
The default libunit behavior relies on blocking the recv() call for port file descriptors, which an application may override if needed. For external applications, port file descriptors were toggled to blocking mode before the exec() call. If the exec() call failed, descriptor remained blocked, so the process hanged while trying to read from it. This patch moves file descriptor mode switch inside libunit.
2020-08-11Libunit refactoring: port management.Max Romanov1-1/+13
- Changed the port management callbacks to notifications, which e. g. avoids the need to call the libunit function - Added context and library instance reference counts for a safer resource release - Added the router main port initialization
2020-07-23Fixing main and application port structs file descriptor init.Max Romanov1-0/+2
Correct value for non-initialized file descriptor is -1, because most of the checks in libunit compares file descriptor with -1 before performing an action. Using 0 as default value, may cause to close file descriptor #0, this may affect application logic. It is not required to list this patch in changelog because impact is not seen by end users.
2020-07-22Fixing buffer overflow check in discovery.Max Romanov1-1/+1
Incorrect check prevents Unit to start without modules. This issue was introduced in 4a3ec07f4b19.
2020-06-23Isolation: fixed build when features aren't detected.Tiago Natel de Moura1-93/+110
2020-05-28Added "rootfs" feature.Tiago Natel de Moura1-38/+443
2020-03-09Refactor of process management.Tiago Natel de Moura1-19/+344
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.

2018-10-09Renamed "go" application type to "external".Valentin Bartenev1-4/+4
There's nothing specific to Go language. This type of application object can be used to run any external application that utilizes libunit API.
2018-08-06Unit application library.Max Romanov1-427/+49
Library now used in all language modules. Old 'nxt_app_*' code removed. See src/test/nxt_unit_app_test.c for usage sample.
2018-07-12Enabled body buffer shared memory segmentation.Max Romanov1-23/+22
Changeset #699 fixes shared memory allocation: continous buffer with requested size should be allocated or function failed. For body longer than 10 Mb, this allocation will definitely fails. For body buffer it is not required to send it in a single continous buffer, so, need to request minimum reasonable amount of shared memory and try to extend it, if possible or allocate next buffer.

2017-10-04Using request mem pool for req<->app link.Max Romanov1-1/+1
Request <-> application link structure (nxt_req_app_link_t) used to register the request in application request queue (nxt_app_t.requests) and generate application-specific port message. Now it is allocated from request pool. This pool created for request parsing and used to allocate and store information specific to this request.
2017-09-16Fixed memory leak caused by mempool related to request context.Valentin Bartenev1-7/+3
The previous attempt of fixing this in e5a65b58101f hasn't been really successful, because the actual memory leak was caused not by the request parse context itself, but its memory pool.
