2019-09-18Fixing request release order to avoid crashes on exit.Max Romanov1-6/+10
Each request references the router process structure that owns all memory maps. The process structure has a reference counter; each request increases the counter to lock the structure in memory until request processing ends. Incoming and outgoing buffers reference memory maps that the process owns, so the process structure should be released only when all buffers are released to avoid invalid memory access and a crash. This describes the libunit library mechanism used for application processes. The background of this issue is as follows: The issue was found on buildbot when the router crashed during Java websocket tests. The Java application receives a notification from the master process; when the notification is processed, libunit deletes the process structure from its process hash and decrements the use counter; however, active websocket connections maintain their use counts on the process structure. After that, when the master process is stopping the application, libunit releases active websocket connections. At this point, it's important to release the connections' memory buffers before the corresponding process structure and all shared memory segments are released.
2019-09-18Go: do not store pointer to Go object.Max Romanov2-2/+49
To pass Go object references to C and back we use hack with casting to unsafe and then to uintptr. However, we should not store such references because Go not guaratnee it will be available by the same address. Introducing map with integer key helps to avoid dereference stored address. This closes #253 and #309 issues on GitHub.
2019-09-18Reducing number of warning messages.Max Romanov1-6/+5
One alert per failed allocation is enough.
2019-09-18Protecting context structures with mutex.Max Romanov1-4/+63
By design, Unit context is created for the thread which reads messages from the router. However, Go request handlers are called in a separate goroutine that may be executed in a different thread. To avoid a racing condition, access to lists of free structures in the context should be serialized. This patch should fix random crashes in Go applications under high load. This is related to #253 and #309 issues on GitHub.
2019-09-18Configuration: added ability to modify object members with slashes.Valentin Bartenev1-39/+49
Example: PUT/POST/DELETE /config/listeners/unix:%2Fpath%2Fto%2Fsocket This follows a49ee872e83d.

2019-09-17Tests: head() method introduced.Andrey Zelenkov1-0/+3
2019-09-17HTTP parser: fixed parsing of target after literal space character.Valentin Bartenev3-3/+63
In theory, all space characters in request target must be encoded; however, some clients may violate the specification. For the sake of interoperability, Unit supports unencoded space characters. Previously, if there was a space character before the extension or arguments parts, those parts weren't recognized. Also, quoted symbols and complex target weren't detected after a space character.
2019-09-16HTTP parser: removed unused "plus_in_target" flag.Valentin Bartenev3-48/+15

2019-09-16Configuration: added ability to access object members with slashes.Valentin Bartenev6-4/+104
Now URI encoding can be used to escape "/" in the request path: GET /config/listeners/unix:%2Fpath%2Fto%2Fsocket/

2019-08-30Fixed WebSocket implementation that was broken on some systems.Max Romanov1-1/+1
The "nxt_http_websocket" request state, defined in "nxt_http_websocket.c", is used in "nxt_router.c" and must be linked with external symbol declared in "nxt_router.c". Due to the missing "extern" keyword, building Unit with some linkers (notably gold and LLD) caused WebSocket connections to get stuck or even crash the router process.

Request state ready_handler required for further websocket events processing. It is not required for regular response transferring.
