This fixes the router's crash on buildbot; the reason was an unexpected 'last'
response from the application to the router arriving before the response
headers. The last buffer is not a memory buffer, so the result of accessing
memory fields is unpredictable.
The unexpected 'last' message was caused by an error in libunit; fixed in
fee8fd855a00.
PyUnicode_GET_SIZE() in deprecated since 3.3 and will be removed in 3.12.
In version 3.9 it was explicitly marked by deprecation warning causing
compilation error with Unit.
PyUnicode_GET_LENGTH() must be used instead.
Data in the queue and the socket are transmitted independently; special
READ_QUEUE and READ_SOCKET message types are used for synchronization.
The warning was accidentally committed with changeset 1d84b9e4b459.
The connection's local socket address is allocated from the connection
pool before the request is passed to the application; however, with keep-alive
connections, this field was unconditionally reset by a socket configuration
value that could be NULL. For the next request, the address was allocated
again from the same connection pool. Nonetheless, all leaked addresses
were released when the connection was closed.
The issue introduced in changeset 5c7dd85fabd5.
Large-bodied requests are added to the request hash to be found when the body
arrives. However, changeset 1d84b9e4b459 introduced a bug: the 'in_hash' flag,
used to remove the request from the hash at request release, was cleared after
the first successful request lookup. As a result, the entry was never removed.
AVIF is a modern image format based on the AV1 video codec. It generally has
better compression than other widely used formats (WebP, JPEG, PNG, and GIF)
and is designed to supersede them. Support was already added to the latest
version of Chrome.
APNG extends PNG to permit animated images that work similarly to animated GIF.
It's supported by most modern browsers.
Also removed duplicated ".svg" entry.
This change aids heap usage analysis in applications.
The alloc and free functions are also required for lvlhash due to the upcoming
threading support, because using main nxt_memalign() and nxt_free() isn't safe
in a multithreaded app environment. The reason is that these functions may use
thread-local structures which aren't initialized properly in applications.
The issue was introduced in changeset 1d84b9e4b459. The request buffer was
transferred via the shared application queue, but the buffer position and the
'sent' flag were not updated after the buffer had been sent.
The Apache HTTP server benchmarking tool, ab, issues HTTP/1.0 requests with
the 'Connection: Keep-Alive' header and expects a 'Connection: Keep-Alive'
header in the response.
Now it is possible to specify the name of the application callable using
optional parameter 'callable'. Default value is 'application'.
This closes#290 issue on GitHub.
If idle connection was closed before h1proto had been allocated
then c->socket.data is NULL. This happens if nxt_h1p_idle_response()
is called by nxt_h1p_idle_close(). However, h1p->conn_write_tail
is used only in nxt_h1p_request_send() that would not be called
after nxt_h1p_idle_response().
The bug was introduced in f237e8c553fd.
Messed up return values in nxt_upstream_find() caused error in applying any
configuration with a valid "pass" value in router configuration pointing to
upstream. That wasn't the case in "listeners" objects, where the return value
wasn't checked.
Also, it caused segfault in cases where the "pass" option was configured with
variables and resulting value was pointing to a non-existent upstream.
Added missing return checks as well to catch possible memory allocation errors.
The bug was introduced in d32bc428f46b.
This closes#472 issue on GitHub.
Now it's possible to disable default bind mounts of
languages by setting:
{
"isolation": {
"automount": {
"language_deps": false
}
}
}
In this case, the user is responsible to provide a "rootfs"
containing the language libraries and required files for
the application.
It's not used since cbcd76704c90.
This option is a leftover from previous IPC between router and applications
processes. It was never documented, though.

Buffer for application prefork request allocated from temp conf mem_pool.
If error response from main process received before buffer completion handler,
temp conf mem_pool destroyed and router may crash in completion handler.
Assertion "src/nxt_buf.c:208 assertion failed: data == b->parent" triggered
when NXT_DEBUG_ALLOC enabled in configure.
This patch disables completion handler and memory allocated for buffer
released with memory pool.
Previously, an error during the prefork phase triggered assert:
src/nxt_port.c:27 assertion failed: port->pair[0] == -1
and resulted in exiting of the main process.
This could be easily reproduced by pushing a configuration with "rootfs",
when daemon is running without required permissions.
