[Firebird-devel] [FB-Tracker] Created: (CORE-4208) IIF and LF CR bug
IIF and LF CR bug
-
Key: CORE-4208
URL: http://tracker.firebirdsql.org/browse/CORE-4208
Project: Firebird Core
Issue Type: Bug
Components: Engine
Affects Versions: 2.5.2
Reporter: Attila Molnár
Priority: Minor
Hi!
SELECT REPLACE('a' || IIF(1 = 1, ' ', ASCII_CHAR(13) || ASCII_CHAR(10)) || 'b',
' ', '*')
FROM rdb$database
returns a*b, but it shold be a**b, due to padding to 2.
SELECT REPLACE('a' || IIF(1 = 1, ' ', x'0D0A') || 'b', ' ', '*')
FROM rdb$database
returns a*, but it shold be a**b, due to padding to 2. Also in this case
padding char is #0, not #32.

If you're planning for Firebird to hang around another 27 years, it's time to define a modern OO API that is easy to use from modern languages, is flexible and extensible, supports an efficient remote protocol, and can fully support the legacy SQL APIs as a proper client layer and maybe even BLR, if that's still important.

Memory is *only* freed when all users disconnect. To reproduce it, just follow the simple procedure below: - Open an ISQL session or an instance of any application using FB. (This session will be the last one to be closed) - Try working with others instances of the same application or open several ISQL sessions using the same DB. Make some heavy operations. - Keep checking the memory every time. (use 'top' command or 'ps axl | grep fbserver') - Close all instances, except the first one. - Check the memory. It is *not* released as it should. - Now close that ISQL session you opened in the beginning. - Check the memory. Now it is all there, given back to the system. I can supply additional information and made additional tests if needed.

SQLDA API is implemented as a layer over it (in FB3 - directly in yvalve, i.e. yvalve currently supports both APIs). OK, I haven't looked at the protocol for about a million years, so consider this a critique of my earlier work, not necessarily the current state of affairs. Network efficiency has a number of elements. The most important is reducing the number of round trips to a bare minimum. Following that (distantly) is minimizing the number of bytes sent. Last is minimizing the CPU load to encode/decode communication packets. The keys to reducing round trips are to bundle metadata with data to eliminate the need for info trips and, most importantly, to batch record retrievals and batch inserts into single large packets. Sending a MB worth of records is obviously a great win. So is implementing the equivalent of the JDBC batch update semantics. The encoding we've been talking about for record encoding is also an excellent encoding for communication, being both dense and platform independent, eliminating the need for separate homogenous / heterogeneous modes of the original Interbase protocol. And, since all numbers and strings can be arbitrarily large without wasting bytes, there are no tradeoffs necessary on field size (as Ann loves to point out, I'm a victim of the bit depression and tend to makes things a little smaller than I should to save space). For both Netfrastructure and NuoDB I've used JDBC as the client API, though the protocols were quite different. One of the advantages of starting over from time to time is that you get/have to re-evaluate everything thing you've done in past, partly for efficiency and partly to avoid accusation of piracy. It's a good habit to get into, however. When you find a better way to something, go for it. A good example of this came up in a master class class I was teaching before I left NuoDB. Somehow we stumbled onto the topic of string to date conversions. While I was pointing out that the worst part of starting a new software company was rewriting stringToDate, a completely new, incredibly efficient, open ended algorithm for that class of conversions occurred to me. It's really cute, and if anyone is interested, I'll describe it. -- Learn the latest--Visual Studio 2012, SharePoint 2013, SQL 2012, more!

[Firebird-devel] Complex String Decoding
A couple of folks asked, so here it is. The scheme centers around pattern strings. A pattern string represents one of any number of possible interpretations of a target string. A pattern string consists of punctuation characters and the characters A and 9 representing consecutive sequences of alphabetical characters or digits. At initialization time, a hash table is generated containing all possible legitimate target string patterns and respectiive rule codes. At decode time, a target string is scanned constructing a) its pattern string and b) a vector of address, length of all alphabetic or numeric sequences found. Since the max length of a legitimate pattern and the maximum number of possible sequences, these can be statically allocated. Some sample string and corresponding patterns: 9/5/20139/9/9with segments 9 5 2013 5.9.13 9.9.9with segments 5 9 13 September 5, 2013A9,9 with segments September 5 2013 After a target string is scanned the hash table is checked for a matching pattern rule. If found, resulting the rule is used as the argument for a case statement to apply the rule to the vector of segments. There is usually a little more work to be done. For dates, for example, it is necessary to validate day and month, look up alphabetic months, and expand two digit years, etc. -- Learn the latest--Visual Studio 2012, SharePoint 2013, SQL 2012, more!
