        * src/rrd_client.c, src/rrd_daemon.c: rrd_client, rrd_daemon: Do not
          require hostnames to contain a dot. Non-FQDN (e.g. "localhost")
          are now supported as well. Anything that does not start with '['
          should be (and is now) treated as <name>[:<port>]. -- Sebastian

        * src/rrd_client.c: rrd_client: Improved error handling / reporting.
          * Report getaddrinfo() errors using gai_strerror(). * Replaced
          "Internal error" with a more verbose error message, if available.
          -- Sebastian Harl

2009-10-04 11:35  oetiker

        * src/rrd_client.c: rrd_client: Do not rewrite path names when
          accessing remote daemons. When talking to a local daemon (thru a
          UNIX socket), relative path names are resolved to absolute path
          names to allow for transparent integration into existing solutions
          (as requested by Tobi). However, when talking to a remote daemon,
          absolute path names are not allowed, since path name translation
          is done by the server (relative to the base directory). --

          -- Sebastian Harl

2009-10-04 11:29  oetiker

        * src/rrd_daemon.c: rrdcached: Improved the "base-dir symlink
          check". The daemon checks if the specified base directory contains
          symlinks by comparing the canonicalized path name (by realpath())
          with the path name specified on the command line. The GNU libc's
          implementation of realpath() removed trailing slashes ('/') from
          the pathname. Thus, specifying a base directory with a trailing
          slash results in rrdcached aborting, complaining about an invalid
          base directory, which is quite annoying imho. Now, trailing
          slashes are removed before comparing the two path names. --

        * src/rrd_daemon.c: rrdcached: Create the pidfile and (UNIX) socket
          directories as well. Those files may be located in a subdirectory
          of, e.g., /var/run/. To avoid the need to manually create (and
          recreate, e.g. in case /var/run/ is on a tmpfs) that subdirectory,
          let the daemon handle the creation of those directories. --

        * src/rrd_fetch_libdbi.c, src/rrd_tool.h: rrd_fetch_libdbi: Fixed

          functions as static. -- Sebastian Harl

          directory, similar to "mkdir -p" on the command-line. -- Sebastian

        * doc/rrdcached.pod, src/rrd_daemon.c: From: Florian Forster
          <octo@leeloo.lan.home.verplant.org> This patch introduces
          per-socket, per-command permissions to the RRD caching daemon,
          RRDCacheD. This allows administrators to limit access to the
          daemon in a fine-grained manner. The patch removes the command
          line option `-L' and introduces `-P' instead. The option must
          appear *before* the `-l' option and the given permissions are set
          for all following sockets or another `-P' option. For example:
          rrdcached -P FLUSH,PENDING -l 10.2.3.4 -P UPDATE -l
          unix:/some/path Allow `FLUSH' and `PENDING' commands to clients
          connected via IPv4 networking and `UPDATE' to clients connected
          via a UNIX domain socket only. There are a couple of exceptions: -
          The commands `HELP' and `QUIT' are always allowed. - If the
          command `BATCH' is allowed, the command `.' is automatically
          allowed, too. By default, i. e. if no `-P' option is specified,
          all commands will be allowed. As a shortcut to reset the behavior
          to the default behavior, you can use the slightly hackish `-P ""'
          syntax. Signed-off-by: Florian Forster

          If running with -F, rrdcached may have crashed due to assertion
          failure before writing all values. -- kevin

        * src/rrd_tune.c: rrd_tune HW Update Allow to set the smoothing
          window (alpha, beta, gamma) to zero. I'm using rrdtool 1.3.8 with
          abberant behavior detection from the Brutlag method. I need to use
          a week seasonality and no smoothing for the SEASONAL and
          DEVSEASONAL. So I use rrdtune in order to set the smoothing window
          to 0.0. This calls the set_hwarg(). But this method is also used
          to tune the alpha, beta and gamma that can't be set to 0.0 So when
          I tune my smoothing window size to 0.0, it returns -1 due to the
          if(window<=0.0) then do nothing. I join here a small correction
          with a differnent method used to set only the smoothing window
          size and allowing it to be zero. -- sylvain.luiset gmail.com

        * src/rrd_restore.c: While restoring, rrd_restore uses between 30
          and 40 times as much memory as the size of the rrd file to be
          restored. This is due to the use of libxml2 for parsing the the
          whole file prior to turning it into rrd structs. This patch
          switches rrd_restore to using the xmlTextReader interface for
          incremental consumtion of xml files. This reduces the memory
          requirements to about twice the size of the rrd file which should
          be quite manageable for most cases. The parsing is about 25% less
          efficient than with the original libxml2 version of rrd_restore.
          This could be in part due to the more liberal use of malloced
          memory. Optimizing this is for another day though. --tobi

        * configure.ac, src/rrd_thread_safe.c: Even though POSIX/XSI
          requires "strerror_r" to return an "int", some systems (e.g. the
          GNU libc) return a "char *" _and_ ignore the second argument (user
          provided buffer). The configure script now checks for that
          behavior using AC_FUNC_STRERROR_R. rrd_strerror() in
          rrd_thread_safe.c has been updated to (hopefully) handle all
          possible cases. Previously, rrd_strerror() would have returned
          "strerror_r failed. sorry!" in mostly any cases when using glibc,
          since "if (strerror_r())" had been used to check for errors which
          evaluates to true if a (non-NULL) pointer was returned. Now, we,
          at least, return the error number in case anything else fails.

          unable to load the driver was producing segmentation faults. b)
          better parsing of datasources * until now timestamp fields had to
          be integer and had to contain a unix timestamp - now you can now
          also use DateTime fields (you still need to specify it, as the
          time-range needs to be defined correctly) * data fields are now no
          longer limited to (var)char or DOUBLE fields - FLOAT, INTEGER,...
          are now also supported. c) there is a bug with at least LIBDBI
          0.8.1 in conjunction with mysql that can result in segmentation
          faults when BINARY/BLOB fields are accessed - rrdtool will now
          tell you about this fact before dying ;) d) also the value of
          rrdderivemaxstep only gets applied if derive has been selected
          correctly. e) "GROUP BY timestamp" has been removed from SQL
          statement. f) "ORDER BY timestamp" will be added only in the case
          of fetching "derived" data. -- Martin Sperl

        * doc/rrdcached.pod, src/rrd_daemon.c: This patch allows for
          multiple RRD writer threads to service the queue. Now, rrdcached
          can have more simultaneous I/O requests into the kernel. This may
          allow the kernel to re-order disk writes, resulting in better disk
          throughput. In practice, throughput is increased by 2-3x. The
          flush (-f) timer maintenance has been moved from queue_thread_main
          into its own thread. Be more careful about when to use
          pthread_cond_signal vs _broadcast, since multiple threads may be
          waiting on &queue_cond. --kevin

        * CONTRIBUTORS, configure.ac, src/Makefile.am, src/rrd_fetch.c,
          src/rrd_tool.h: As some of you may know that I have created a
          patch for rrdtool 1.2 a few years ago, so that a database could be
          queried for values for graphing. The patch has been mostly
          rewritten and the following changes have been made: * high
          dependency on mysql has been reduced by avoiding the temporary
          tables (which was bad for mysql replication) * The number of
          executed SQL-Statements for one CDEF has been reduced to 1
          compared to 11 SQLs (including CREATE TEMPORARY TABLE) - for patch
          against version 1.2 * All consolidation is done in rrdtool itself
          (MIN,MAX,AVERAGE) * Additional consolidation functions are COUNT
          and SIGMA, which give information on statistics on a per
          "time-bin" basis. * All these consolidation values are always
          returned as separate columns, that are returned by RRD and the
          consolidation function given as Argument is ignored. Main reason
          is that this way there is only one call to rrd_fetcht and thus the
          database even if we need to fetch for example min, avg and max.
          Compare this to 3 calls in case of different consolidation
          functions - and if you want to get SIGMA and COUNT as well it is
          still only one call to the backend and the database. * Some
          previous existing features have been taken out at the moment to
          allow for this reduced set of SQL queries. o prediction using the
          values from the last X days at the same time o the corresponding
          sigma calculation * The idea is to create generic CDEF's that will
          do the same thing, but that is also available when using RRD-files
          (similar to TREND, but with another scope) This will get posted as
          a separate patch. * Overall performance should be much better and
          the patch as a whole simpler. * The patch also includes
          modifications to the configuration infrastructure, to make libdbi
          support optional. -- Martin Sperl

        * src/rrd_daemon.c: Much simpler handling of timestamp errors.
          Return an error to the user when any of the time stamp values are
          invalid. This is similar to RRDTool's normal behavior. Removed the
          complex logic previously used to return error codes to the user.
          This solves a bug where non-advancing timestamps could have
          produced incorrect error output during "BATCH" mode. The bug was
          cause by using the sock->wbuf pointer for the error output. --

          I added that line in my first patch, following perl, python and
          ruby build style, but it's not needed after I switched to

        * src/rrd_daemon.c: The previous code relied on the assumption that

        * src/rrd_daemon.c: remove_cache_item() did not check whether a file
          was in queue before modifying the cache head/tail pointers.
          Therefore, the process of flushing old files may perturb the
          cache_queue_head pointer. This caused some nodes with
          CI_FLAGS_IN_QUEUE to be un-linked from the queue list. Thereafter,
          they would not be flushed by any periodic process (although they
          could be revived with FLUSH or UPDATE). This caused a slow memory
          leak for files that are no longer updated. Pending updates for
          these "abandoned" files would remain in memory ad infinitum. With
          this patch, remove_from_queue() will check that the item is queued
          before modifying the head/tail pointers. This restores the
          intended behavior. --kevin

          This moves selection of the initial RRA row into the rrd_open.c

          However, it now provides an opportunity for alternative
          implementations to integrate with rrdtool in a single place. Maybe
          there are other places in rrdtool where I should insert calls to
          the function rrd_notify_row()? This has been tested with rrdtool
          create and rrdtool info to verify that random rows are selected by

          multiple output lines. All routines now pass around
          listen_socket_t objects instead of file descriptors. All I/O is
          now contained in two routines. It's no longer necessary to specify
          the line count in multi-line outputs, since that is calculated
          automatically. This is the foundation for accepting batched

        * doc/rrdcached.pod, src/rrd_daemon.c: Now, moving a value to the
          head of the queue is O(1). Before it was O(queue size). This
          improves performance of individual flushes when there is a large
          number of files in the queue. As a result, we don't hold the
          cache_lock as much. Revamped enqueue_cache_item to take advantage
          of the new structure. Renamed _wipe_ci_values to look nicer with
          other code. --kevin

        * doc/rrdcached.pod, src/rrd_daemon.c: This patch introduces the
          concept of socket privilege levels. "UPDATE" and "FLUSHALL"
          commands are restricted to high-privilege sockets. "FLUSH"
          commands can be executed on any socket. This is ideal for
          multi-user installations where only certain users need write
          access to the RRD files. Now, nearly all socket information is
          passed around the daemon in listen_socket_t data structures. In
          case there is other per-socket state (i.e. if we add
          authentication) we can put it there. Also, I created a new
          "open_listen_socket_network" and removed the network setup from
          "open_listen_socket". -- kevin

        * src/rrd_daemon.c: The PID file is created with open() in the

          created, it complains verbosely to stderr. The PID file is written
          in the child process. The only way the fdopen() will fail on a fd
          that is already open is if you're completely out of memory. As in
          other places in the code, I didn't consider this a case that
          required a very verbose message. (Search for "strdup failed"). If
          you still think a more verbose message is called for, please
          suggest one. The attached patch corrects the error message to
          complain about fdopen() vs fopen(). I hadn't noticed that until

        * doc/rrdcached.pod, src/rrd_daemon.c: Support for IPv6 has been

          destroy correctly formatted IPv6-addresses. This patch checks for
          dots '.' in the address. If the address contains at least one dot,
          it is considered to be a hostname or an IPv4-address and a simple
          search for a colon is done. If no dot is found, the code will
          check for an opening square bracket '[' at the beginning of the
          address. If one if found, the format [address]:port is assumed. If
          neither applies, the default port will be used. -- Florian Forster

          read. This patch changes the communication code to use the (line
          based) `fgets' function rather than the lower level `read'
          function. After reading the first line (which contains the total
          number of line to be expected), this precise number of lines is
          read - blocking if necessary. Also, the missing four new statistic

        * src/rrd_gfx.c: The attached patch converts the given string to
          UTF-8 using glib's g_locale_to_utf8() function. This function
          expects the string to be encoded as specified by the locale
          settings, so this will fail if e.g. you're using some script which
          is encoded in some way incompatible to the locale settings. In
          this case, the patch falls back to use the original string as
          provided by the user as there is no way to tell how to interpret
          that string. So, in this case, you will still get the old behavior
          (that pango warning and messed up strings in the graph). However,
          imho this is perfectly fine since it should be up to the user to
          take care of a sane environment. -- Sebastian Harl

          tokkee.org Date: Sun, 8 Jun 2008 15:01:05 +0200 Subject: [PATCH]
          Cleanup the symbols exported by librrd. Up to know librrd exported
          a lot of symbols, most of which are to be regarded as private
          symbols. This somewhat pollutes the API as the symbols could, in
          theory, be used by external software and, more importantly, makes
          symbol based dependencies (as recently introduced in e.g. Debian)
          somewhat harder to implement. This patch does a somewhat
          large-scale cleanup of the exported symbols: * Introduced a
          librrd.sym file which contains all symbols that are to be
          exported. This file is then passed to libtool using the
          -export-symbols option which tells the linker to export the given
          symbols only (note: according to the libtool manual, this has no
          effect on some architectures - however, I assume that most
          architectures in use today do support it). librrd.sym contains all
          symbols originally defined in rrd.h sans LockRRD() (which has been
          moved to rrd_tool.h). The following functions have been added to
          rrd.h and the list of exported symbols (some of them have been
          renamed, see below): - rrd_info() - rrd_info_free() -
          rrd_info_print() - rrd_info_push() - rrd_lastupdate() -
          rrd_update_v() - rrd_strerror() * Prefixed all public functions
          and types with "rrd_" to avoid name clashes with other libraries.
          Also, while I was at it, I introduced typedefs for all custom
          types and prefixed the time names with "_t" to improve
          consistency: - enum info_type -> rrd_info_type_t - enum timetype
          -> rrd_timetype_t - union infoval -> rrd_infoval_t - struct info_t
          -> rrd_info_t - struct rrd_context -> rrd_context_t - struct
          rrd_time_value -> rrd_time_value_t - info_free() ->
          rrd_info_free() - info_free() -> rrd_info_free() - info_print() ->
          rrd_info_print() - info_push() -> rrd_info_push() - LockRRD() ->
          rrd_lock() (not public though) - parsetime() -> rrd_parsetime()
          (and: src/parsetime.c -> src/rrd_parsetime.c) - proc_start_end()
          -> rrd_proc_start_end() - set_to_DINF() -> rrd_set_to_DINF() -
          set_to_DNAN() -> rrd_set_to_DNAN() * Moved readfile() from
          rrd_open.c to rrd_cgi.c and declared it static. This function is
          used in rrd_cgi.c only. * rrd_lock() (f.k.a. LockRRD()) now
          accepts a rrd_file_t pointer instead of an integer to increase
          encapsulation.

          time. There was a long standing (even documented) missfeature in
          rrdtool which caused uknown-data to be accepted as long as it was
          less than the mrhb. This was never the intended behaviour and had
          interesting side effects
          (http://oss.oetiker.ch/rrdtool-trac/ticket/125): If you have a 60
          Second step with 59s unknown data and 1 second of known data the
          whole become known data as long as the mrhb was > step. The
          intended behaviour was that a step should become unknown as soon
          as it contains more than 50% of unknown data. The patch fixes both
          the documentation and the code.

          cross block boundaries simultaneously, which is sub-optimal. Also,
          this patch enables the user to see the RRA's cur_row pointer via

        * src/rrd_update.c: Fix for HoltWinters phase-shift bug described
          below. When one or more primary data point times were missed, the
          SEASONAL and DEVSEASONAL archives were marked as being up-to-date,
          so that they would not be written to. It was correct not to write
          to these archives, but the code failed to advance the pointers
          within the SEASONAL and DEVSEASONAL archives so that future
          updates would go to the correct location in the archives. Rather
          than mark these archives as up-to-date (by setting
          rra_step_cnt[rra_idx] = 0), my patch allocates a new "skip_update"
          array that is set to 1 for SEASONAL and DEVSEASONAL archives that
          have missed one or more primary data points. When an RRA is
          written to, the cur_row pointer advancement happens for all
          archives, but the skip_update array is checked just before
          actually writing out the changes. Please give it a whirl! -- Evan

          src/rrd_tune.c, src/rrd_update.c: There are two popular variants
          of the Holt-Winters forecasting method; RRDtool supports the
          "additive" method, which means that seasonal variation is simply
          added to the baseline. For our application, it would be more
          appropriate to use the "multiplicative" Holt-Winters method, where
          seasonal variation is a coefficient multiplied by the baseline.
          Quick example to illustrate the difference: if the average doubles
          season-over-season, the additive method would predict the delta
          between min and max to be constant, whereas the multiplicative
          method would predict the delta to double as well. Attached is a
          patch against trunk to support the multiplicative method. I've
          done this with a new consolidation function, MHWPREDICT, which is
          essentially interchangeable with HWPREDICT. There is a noticeable
          improvement in prediction deviations for certain types of
          functions; the attachments show HWPREDICT and MHWPREDICT
          predictions for a function with an x*sin(x) component. Because
          HWPREDICT and MHWPREDICT differ only in their equations, I've
          factored out their math into rrd_hw_math.c. The appropriate
          smoothing functions are passed to the update functions in a
          container of function pointers, which are called where
          appropriate. Thus the additive and multiplicative methods use the
          same update functions, and the right equations are evaluated
          without having flag checks everywhere. This approach, I think,
          makes the algorithms quite clear, with minimal duplicate code. I
          have moved update_hwpredict, update_seasonal, update_devpredict,
          update_devseasonal, and update_failures into a separate file,
          rrd_hw_update.c, with some slight refactoring related to
          rrd_hw_math.c. I ran some regression tests against trunk to make
          sure I didn't break anything with the existing HWPREDICT code.
          MHWPREDICT uses the same deviation smoothing and failure detection
          algorithms as HWPREDICT. Some helpful references on the
          multiplicative Holt-Winters method:

          variations to the multiplicative Holt-Winters, including variance
          calculations; FYI, my implementation uses "Model 1") My employer
          and the owner of this patch (IMVU, Inc.) is happy to license it
          under the same terms as RRDtool, i.e. give it to the project. --

          src/rrd_tool.h, src/rrd_update.c: Updates from Bernhard Fischer
          rep dot nop gmail com - fix typo in rrd_fetch where rrd_read
          result was checked against an incorrect size. - in rrd_fetch, drop
          rrd_head_size in favour of rrd_file->header_len - in rrd_fetch,
          make the message "post fetch" unambiguous (now past vs. post). -
          change usage of param rdwr of rrd_open: allow for RRD_READONLY,
          RRD_READWRITE, RRD_CREAT, RRD_READAHEAD; adjust callers
          accordingly: + rrd_resize needs CREAT + rrd_dump may want
          READAHEAD - implement FD based I/O in rrd_open, rrd_read,
          rrd_write, rrd_seek. - in rrd_update, unify write_RRA_row(). -
          sort | uniq the -T in .indent.pro (info_t was duplicated) - add
          stub of an option to use O_DIRECT to the configury - in
          Makefile.am, simplify the "indent" invocation of find: My find may
          not support "-o" resp. "-or" nor braces. Using -name "*.[ch]"
          works everywhere, AFAIK.
