2018-10-09Renamed "go" application type to "external".Valentin Bartenev1-21/+21
There's nothing specific to Go language. This type of application object can be used to run any external application that utilizes libunit API.
2018-09-20Resetting init->stream for ready process.Max Romanov1-0/+4
Router requests application start by sending port message with application parameters to master. In response router gets application port. Stream id used to link request and response. If application process terminates unexpectedly (e.g. before ready state), it is required to notify router about application start failure. For this purpose stream id is stored in process initialization parameters. Stream id sequentially incremented and starts from 1 in case of router resurrection. New router application start stream id may coincide with stream id of currently running/terminating application processes. In such cases router may receive REMOVE_PID message with same stream id as used in application start request and mistakenly reports application start failure. This commit tries to avoid such errors by resetting stream for processes in ready state.
2018-09-20Controller: certificates storage interface.Valentin Bartenev1-16/+38
2018-09-07Misspelled variable names fixed.Max Romanov1-1/+1
2018-08-10Stopping all application processes if router process dies.Max Romanov1-1/+27
Unit master process restarts the router if the router accidentally dies. New router process receives the configuration from controller and starts configured applications. The information of running applications cannot be transferred to router because currently there is no persistent application identifier. To avoid orphan application processes started by died router, master process stops all currently running applications once it receives SIGCHLD for router process.
2018-06-18Fixed exit status on start failure.Igor Sysoev1-3/+3
This and previous commit close #131 issue on GitHub.
2018-06-18Removing Unix control socket on start failure.Igor Sysoev1-1/+1
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.

2018-02-20Removed unwanted assertions.Max Romanov1-2/+3
2018-02-14Fixed race condition while discovering modules.Valentin Bartenev1-0/+9
Previously, the discovery process might exit before the main process received a list of available modules.
2018-02-13Improving configuration field mapping names.Max Romanov1-16/+25
Avoiding word 'common' as too common. Couple of assertions reduced to error messages.
2018-02-09Fixed starting of applications with specified version.Valentin Bartenev1-5/+15
The "type" option can contain version number that need to be cut off before calling nxt_app_parse_type(). The bug was introduced in 4979fe09d9cd.
2018-02-02Fixed typo in assertion statement introduced in 4979fe09d9cd.Max Romanov1-1/+1
Found by Coverity (CID 260375).
2018-01-31Added Perl support.Alexander Borisov1-2/+42
2018-01-29Introducing extended app process management.Max Romanov1-6/+0
- Pre-fork 'processes.spare' application processes; - fork more processes to keep 'processes.spare' idle processes; - fork on-demand up to 'processes.max' count; - scale down idle application processes above 'processes.spare' after 'processes.idle_timeout'; - number of concurrently started application processes also limited by 'processes.spare' (or 1, if spare is 0).
2018-01-24Fixed formatting in nxt_sprintf() and logging.Sergey Kandaurov1-1/+1
2018-01-24Using size_t for the field width type of the "%*s" specifier.Sergey Kandaurov1-6/+8
2018-01-11Changing relative php scripts paths to real ones.Max Romanov1-1/+1
This is required to run phpMyAdmin.
2017-12-28Removed duplicate declaration.Igor Sysoev1-1/+1
2017-11-29Introducing python virtualenv configuration.Max Romanov1-0/+6
New parameter 'home' for python application allows to configure application-specific virtualenv path. This closes #15 issue on GitHub.

2017-10-19Fixed controller restarting.Valentin Bartenev1-23/+35
Previously, stored configuration wasn't reread on controller process restart, which resulted in segmentation fault.
2017-10-19Filtering process to keep connection.Max Romanov1-0/+7
- Main process should be connected to all other processes. - Controller should be connected to Router. - Router should be connected to Controller and all Workers. - Workers should be connected to Router worker thread ports only. This filtering helps to avoid unnecessary communication and various errors during massive application workers stop / restart.
2017-10-10Optimized application type handling.Valentin Bartenev1-8/+4
2017-10-05Improved applications versions handling.Valentin Bartenev1-11/+4
2017-10-04Port message fragmentation supported.Max Romanov1-8/+28
- Each sendmsg() transmits no more than port->max_size payload data. - Longer buffers are fragmented and send using multiple sendmsg() calls. - On receive side, buffers are connected in chain. - Number of handler calls is the same as number of nxt_port_socket_write() calls. - nxt_buf_make_plain() function introduced to make single plain buffer from the chain.
2017-10-04Introducing process use counter.Max Romanov1-2/+7
This helps to decouple process removal from port memory pool cleanups.
2017-10-04Introducing use counters for port and app. Thread safe port write.Max Romanov1-5/+10
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.
2017-10-04Using engine memiory pool for port write allocations.Max Romanov1-2/+4
To allow use port from different threads, the first step is to avoid using port's memory pool for temporary allocations required to send data through the port. Including but not limited by: - buffers for data; - send message structures; - new mmap fd notifications; It is still safe to use port memory pool for incoming buffers allocations because recieve operation bound to single thread.
