2f189cb153 Log manager erroneously wrote string termination character after every log message.
Added a few trivial test cases.

baed0e846f Changed log_manager to use block-siuze buffers instead of small write buffers. Added new test cases and added iterations. Added possibility to test with dummy disk write which sleeps constantly for 5ms instead of performing disk write. 2013-07-23 08:34:43 +03:00
6abd9dbdaa Added profile counters: writebuffer init, done, total and recycle counts. 2013-07-02 16:53:23 +03:00
d11741130d Changed log manager API to support variable length formatted log strings. New API is as follows:
/** No change in these */
bool skygw_logmanager_init(void** buf, int argc, char* argv[]);
void skygw_logmanager_done(void** buf);
void skygw_logmanager_exit(void);
int  skygw_log_flush(logfile_id_t id);

/** writebuf remains unused, but formatted string is now possible and in case 
 * of formatted string, arbitrary long argument list is supported too. Max 
 * length for a log string is defined to BUFSIZ, whose value depends on the 
 * system but typically is 4/8KB.
 */
int  skygw_log_write(void* writebuf, logfile_id_t id, char* format, ...);
int  skygw_log_write_flush(void* writebuf, logfile_id_t id, char* format, ...);

makefile.inc includes new CFLAG : SS_PROF, which is set if PROF=Y on make command line or in build_gateway.inc .
ss_debug.h includes corresponding ss_prof(exp) macro which equals to exp if SS_PROF is defined and to empty if in other case.

mlist_t now includes datadel function which is a callback and it is executed for mlnode_data on node exit.

5c271e1925 Fixed clean-up processes in cases where initialization fails arbitrarily in the middle of startup. Added four descriptive states : UNINIT, INIT, RUN, DONE for flat stucts inside logmanager. Flat structs always have the state which tells what needs to be fred, if any. 2013-06-27 16:43:01 +03:00

2b8c62a7da Added a few more testcases to increase IO and added debug printing for file handling. 2013-06-26 23:40:07 +03:00
b74423121f Removed references to epoll code. 2013-06-26 23:26:21 +03:00
c8831f0a89 I didn't know these even existed in bazaar. Now they are removed. 2013-06-26 23:18:36 +03:00
ef1d198654 Changed log manager API so that pointer reference to logmanager is not used anymore. Every call initializes logmanager now except skygw_logmanager_done and skygw_log_flush.
skygw_logmanager_init is still useful because it allows for providing memory address for log manager where it can store a list of preallocated write buffers. TBD.

Logmanager access is now protected with spinlock familiar from epoll/core/spinlock.c . It is modified to avoid trashing; misses are counted and every tenth subsequent lock acquiring attempt triggers short random sleep.

2ea8e2a05a Added licences and changed the use of zero-length arrays due to compiler problems. 2013-06-26 09:39:38 +03:00
b82ee51b7a Tiny changes, more tests. 2013-06-25 22:13:48 +03:00
8178e4e239 New, yet primitive version of log writing functionality. Fixed some things in utils. 2013-06-25 21:14:03 +03:00
