If a complete response is delivered in many buffers, then calling
gwbuf_length() whenever you need the complete size starts to hurt.
By caching the length of the data received sofar and by updating
the length in clientReply(), gwbuf_length() will be called exactly
once for each buffer(chain) delivered to routeQuery().
When the databases are mapped, it is desirable to get the complete
response in one contiguous buffer. This removes the need to manually
process the partial packets in the router code.
test_poll was calling poll_init() two times since it's already included in
init_test_env().
test_queuemanager was missing a bunch of frees. This doesn't fix it completely,
but removes most of the leaks and valgrind errors.
If the output buffer given to pcre2_substitute is too small, an error
value is written to the last parameter (output length). That value
should not be used for calculations. This patch gives a copy as
parameter instead.
Coincidentally, this commit fixes the crashes of query classifier tests.
Also, increase buffer growth rate in utils.c.
If a client connects from an IPv4 address, but the listener listens on an
IPv6 address, the client IP will be a IPv6 mapped IPv4 address
e.g. ::ffff:127.0.0.1. A grant for an IPv4 address should still match an
IPv6 mapped IPv4 address.
When users were loaded, the permissions for the service user were
checked. The conditional that makes sure the check is executed only at
startup was checking the listener's users instead of the SQLite handle
which caused all reloads of users to check the permissions.
This reverts commit f3c83770903151a0a3b53593c3e05fa0af94cd5f. The
functionality was used implicitly by modules that declare the
RCAP_TYPE_CONTIGUOUS_OUTPUT capability.
The help messages are now more descriptive and have usage information in
them. This should help users use the commands without relying on the
online documentation.
The line length limitation is now increased to 16384 bytes. It is now
clearly documented in the limitations document.
The configuration parser now uses memory from the heap instead of the
stack. This should remove any problems caused by the larger line length.
The RCAP_TYPE_STMT_OUTPUT is not used in its previous form. It can be
altered to route only complete packets back to the client. This allows
routers to do safer parsing on the results.
