* [multiple] reduce redundant NULL buffer checksGlenn Strauss2021-08-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit is a large set of code changes and results in removal of hundreds, perhaps thousands, of CPU instructions, a portion of which are on hot code paths. Most (buffer *) used by lighttpd are not NULL, especially since buffers were inlined into numerous larger structs such as request_st and chunk. In the small number of instances where that is not the case, a NULL check is often performed earlier in a function where that buffer is later used with a buffer_* func. In the handful of cases that remained, a NULL check was added, e.g. with r->http_host and r->conf.server_tag. - check for empty strings at config time and set value to NULL if blank string will be ignored at runtime; at runtime, simple pointer check for NULL can be used to check for a value that has been set and is not blank ("") - use buffer_is_blank() instead of buffer_string_is_empty(), and use buffer_is_unset() instead of buffer_is_empty(), where buffer is known not to be NULL so that NULL check can be skipped - use buffer_clen() instead of buffer_string_length() when buffer is known not to be NULL (to avoid NULL check at runtime) - use buffer_truncate() instead of buffer_string_set_length() to truncate string, and use buffer_extend() to extend Examples where buffer known not to be NULL: - cpv->v.b from config_plugin_values_init is not NULL if T_CONFIG_BOOL (though we might set it to NULL if buffer_is_blank(cpv->v.b)) - address of buffer is arg (&foo) (compiler optimizer detects this in most, but not all, cases) - buffer is checked for NULL earlier in func - buffer is accessed in same scope without a NULL check (e.g. b->ptr) internal behavior change: callers must not pass a NULL buffer to some funcs. - buffer_init_buffer() requires non-null args - buffer_copy_buffer() requires non-null args - buffer_append_string_buffer() requires non-null args - buffer_string_space() requires non-null arg
* [core] make insert_dup an optional array methodGlenn Strauss2021-08-271-7/+1
| | | | | make insert_dup an optional array method in data_methods (currently used only for merging strings of type data_string)
* [core] move data_{array,integer,string} to array.cGlenn Strauss2021-05-201-4/+1
| | | | | | | | | | | move native data_* types into array.c (the types are already declared in array.h) The array data structure remains extendable, as is done with data_config (configfile) and data_auth (mod_auth), though array data structure primary uses are at startup (config time) and header parsing. The insertion logic into sorted list can be expensive for large lists, so header parsing might choose a different data structure in the future.
* [core] consolidate config printing codeGlenn Strauss2021-05-201-71/+0

* [multiple] PCRE w/ PCRE_STUDY_JIT_COMPILE (fixes #2361)Glenn Strauss2021-03-221-19/+29
| | | | | | | | | | | | | | | | | | | | | | | | | enabled by default disable using server.feature-flags += ("server.pcre_jit" => "disable") Available since pcre-8.20 (2011), and improved in pcre-8.32 (2012), PCRE_STUDY_JIT_COMPILE can greatly speed up repeated execution of PCRE patterns. (https://zherczeg.github.io/sljit/pcre.html) lighttpd continues to use pcre_exec() instead of pcre_jit_exec(), even though doing so does not realize all of the performance increase potentially available with PCRE_STUDY_JIT_COMPILE and pcre_jit_exec(). pcre_jit_exec() is available with PCRE 8.32 and later, if PCRE is compiled with --enable-jit, but lighttpd does not currently use pcre_jit_exec() since the PCRE library might not have been compiled with --enable-jit (though this could be solved with a weak symbol). Similarly, lighttpd does not currently configure the pcre_jit_stack. (Using pcre_jit_exec() may be revisited in the future.) x-ref: "add support for pcre JIT" https://redmine.lighttpd.net/issues/2361

* quiet clang analyzer scan-build warningsGlenn Strauss2020-07-081-0/+1
| | | | | | | | | | (expansion of buffer_string_lenth() inline function and CONST_BUF_LEN() macro, which always check for NULL, appears to cause the analyzer to believe that a pointer might be NULL in cases where it otherwise can not be NULL) x-ref: http://clang-analyzer.llvm.org/faq.html

* [core] perf: array.c performance enhancementsGlenn Strauss2020-02-241-1/+1
| | | | | | | | | | | | | | | | | | | | | mark array_get_index() as hot, rewrite to be pure and return sorted pos mark routines as pure, as appropriate mark routines as cold if used only at startup for config processing mark params const, as appropriate array_get_buf_ptr() for modifiable value buffer after insert into array uint32_t used and size members instead of size_t remove a->unique_ndx member; simply add to end of array for value lists remove du->is_index_key member; simply check buffer_is_empty(du->key) array_insert_key_value() used to be a hint that lookup could be skipped, but the state from array_get_index() is now saved and reused internally, so the distinction is no longer needed. Use array_set_key_value().
* [core] perf: simple, quick buffer_clear()Glenn Strauss2018-11-231-3/+3
| | | | | | | | | quickly clear buffer instead of buffer_string_set_length(b, 0) or buffer_reset(b). Avoids free() of large buffers about to be reused, or buffers that are module-scoped, persistent, and reused. (buffer_reset() should still be used with buffers in connection *con when the data in the buffers is supplied by external, untrusted source)

* [core] fix conditional cache handlingStefan Bühler2016-02-211-6/+6
| | | | | | | | | | | | | | | - add new "skip" result to mark conditions that didn't actually get evaluated to false but just skipped because the preconditions failed. - add "local_result" for each cache entry to remember whether the condition itself matched (not including the preconditions). this can be reused after a cache reset if the condition itself was not reset, but the preconditions were - clear result of subtree (children and else-branches) when clearing a condition cache From: Stefan Bühler <stbuehler@web.de> git-svn-id: svn://svn.lighttpd.net/lighttpd/branches/lighttpd-1.4.x@3082 152afb58-edef-0310-8abb-c4023f1b3aa9

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * remove unused structs and functions (buffer_array, read_buffer) * change return type from int to void for many functions, as the return value (indicating error/success) was never checked, and the function would only fail on programming errors and not on invalid input; changed functions to use force_assert instead of returning an error. * all "len" parameters now are the real size of the memory to be read. the length of strings is given always without the terminating 0. * the "buffer" struct still counts the terminating 0 in ->used, provide buffer_string_length() to get the length of a string in a buffer. unset config "strings" have used == 0, which is used in some places to distinguish unset values from "" (empty string) values. * most buffer usages should now use it as string container. * optimise some buffer copying by "moving" data to other buffers * use (u)intmax_t for generic int-to-string functions * remove unused enum values: UNUSED_CHUNK, ENCODING_UNSET * converted BUFFER_APPEND_SLASH to inline function (no macro feature needed) * refactor: create chunkqueue_steal: moving (partial) chunks into another queue * http_chunk: added separate function to terminate chunked body instead of magic handling in http_chunk_append_mem(). http_chunk_append_* now handle empty chunks, and never terminate the chunked body.
