testsuite.
2017-08-05Minor fixSergey Poznyakoff1
2016-04-21Rewrite SQL configuration support.Sergey Poznyakoff4
Multiple configurations can be provided, by calling dbrw.config from branches of a conditional VCL statement. The only requirement is that exactly one dbrw.config is executed within a single HTTP session. This allows the user to select rewrite data from various databases depending on some conditions. Open SQL connections are stored in a pool and reused as needed. So far no limit on the number of connections is imposed. This is a TODO. Connections remain open during the lifetime of the module (i.e. for as long as varnish is not restarted). * src/dbrw.h (dbrw_config): New members: param_str, magic and list. (dbrw_connection): New members: magic, busy, list. * src/vmod_dbrw.c (dbrw_connection_get) (dbrw_connection_release): New functions. (dbrw_event): Install atexit function. (vmod_config): Keep a pool of configurations. (dbrw_sethdr) [VARNISHVERSION]: Remove leftover code. (vmod_rewrite): Rewrite. * src/vmod_dbrw.vcc (config, rewrite): Mark as PRIV_TASK. * doc/vmod-dbrw.3: Update docs. * doc/vmod-dbrw.texi: Update docs. * configure.ac: Raise version number

* src/vmod_dbrw.c (WS_Copy): Fix definition.
2014-11-12Improve the testsuiteSergey Poznyakoff1
New macro AT_DBRW_INIT ensures the test database is initialized. When finished, it creates the file .TESTINIT if the initialization succeeded or FAILURE, if it did not. The latter contains the error output from initdb. These files are then used to decide whether to proceed with the tests. All tests include this macro at the very beginning. * tests/Makefile.am (CLEANFILES): Add files. * tests/atlocal.in (INITFILE, FAILFILE): New variables. * tests/initdb.at: Rewrite as a new define AT_DBRW_INITDB. * tests/exact01.at: Include AT_DBRW_INIT at the start, Use AT_DBINIT_PREREQ * tests/testsuite.at (AT_DBRW_INIT, AT_DBINIT_PREREQ): New macros. * tests/rewrite01.at: Likewise. * tests/rewrite02.at: Likewise. * tests/rewrite03.at: Likewise. * tests/rewrite04.at: Likewise. * tests/rewrite05.at: Likewise. * tests/rewrite06.at: Likewise.

2013-07-12Optional flags modify the regexp handling, return status and query disposition.Sergey Poznyakoff2
The flags can be supplied globally, using the "flags=X" parameter to drw.config, or for each record individually, by returning X in the fourth column of a tuple. In both cases X is a comma-separated list of: NC or nocase - force case-insensitive regexps case - force case-sensitive regexps (the default) QSA or qsappend - treat destination field as URL; append any query string from the original request URL to it QSD or qsdiscard - treat destination field as URL; discard any query string attached to the incoming URI R=NNN or redirect=NNN - on success, set the X-VMOD-DBRW-Status header to NNN, which must be a valid HTTP status code. * src/dbrw.h [HTTP_STATUS_LEN]: New define. <dbrw_config> (qdisp, regflags, status): New members. * src/vmod_dbrw.c (QDISP_NONE, QDISP_APPEND) (QDISP_APPEND): New constants. (dbrw_init): Fill allocated memory with zeroes. (is_http_status,parse_flags): New static functions. (vmod_config): Re-initialize conf on failure. Initialize new members of struct dbrw_config. (expand_backref): Additional argument 'qry' supplies the query part to be appended to the resulting string. (findmatch): Accept four fields per tuple, the optional fourth one supplying flags.
