Change Log

Version	Changes
0.9.24 Mon Jul 21 2008	Put some more sense into the application templates created by grace mkproject. Add <xml.option.defaulttagkey/> to the xmlschema option section, indicates that any tags with an unknown type should assume their tagname to be the node's key. Fixed offset-bug in string::strcat(). Added class udpsocket for sending and receiving datagrams.
0.9.23 Mon Jun 30 2008	Fixed a bug in string::replace() when dealing with high ASCII or UTF characters. Rigged the process class to never get the child process confused about outstanding lock objects, by declaring its environment to be single-threaded (which it is). This makes the systemprocess class more robust. Rewrote the mkproject utility to be more flexible. It now also allows for setting up projects that don't use the .app bundle directory structure. Rewrote the mkapp utility. Fixed an issue where value::sort() would still lead to a messed up tree linking node keys. Changed value::sort()'s sorting algorithm from fugly bubblesort to something a bit more sane.
0.9.22 Fri Jun 13 2008	Removed a lot of unnecessarily inlined code. Added flag::savetype default argument to value::saveshox(). Added a top-level Makefile and configure script. Built-in schemas are now grace-encoded in the source.
0.9.21 Fri Jun 6 2008	Fixed a problem where httpsocket would sometimes deal badly with a dropped connection when it was using HTTP keepalive. Fixed a bug in string::strstr that would overflow memory bounds in some circumstances. Fixed timezone handling inside class timestamp. Fixed a bug in httpsocket GET handler (it never sent a valid HTTP request due to control flow misalignment). Fixed a parser bug in system regular expression handling.
0.9.20 Fri May 23 2008	Rudimentary support for formatting UTF-8 text in terminal screens.
0.9.19 Fri May 16 2008	Minor bugfix to terminal handling.

0.9.17 Wed Mar 19 2008	Improvements to command line handling code.
0.9.16 Thu Mar 13 2008	A string object can now contain a substring of another string object without keeping a private copy. Added support for Bitvise Tunnelier's braindead interpretation of vt100/xterm emulation (sending <ESC>+'O' where grownups send <ESC>+'[').

0.9.6 Thu Feb 14 2008	Fix interaction between class value and class ipaddress Fix bug in parsing a currency value out of a string.
0.9.5 Tue Feb 12 2008	Fix keyboard readahead in class terminal.
0.9.4 Fri Feb 8 2008	Support JSON-encoding through %format. Grace is now a shared library. Applications using daemon can now use the globally available log::write() function instead of daemon::log(). The fin, fout and ferr file objects are now globally available (no longer tied to the application class). Trees of value objects can now easily be constructed using the '$(key,value) -> $(key, value)' notation. Added support for reading and writing JSON-encoded strings. Added $appobject() macro, deprecates APPOBJECT(). Added $version() macro. Added $exception() macro, deprecates THROWS_EXCEPTION().

0.9.0 Private release	Support JSON-encoding through %format. Grace is now a shared library. Applications using daemon can now use the globally available log::write() function instead of daemon::log().

0.8.15 Fri Oct 5 2007	Fixed a memory leak in value::rmval(). Fixed a memory leak in the assignment of a tcpsocket object to pointer. Added python-style string formatting using %format. Tweak arguments for value::toxml() and value::savexml(). Apple .plist is now a built-in schema. Tweak thread messaging: It now officially makes more sense to use thread::sendevent ("command") or, its brother, thread::sendevent ("command", (value) data). Add new database library 'querido'. Currently only supports sqlite. Add value::insertval() as a sidekick to value::newval(). Fixed some issues with scriptparser. Added class sessionlist for implementing sessions with timeout over stateless protocols. kernel.pwcrypt.verify() now supports salted MD5 passwords regardless of what the native crypt() supports.
0.8.14 Tue Mar 13 2007	Fixed a number of tab-handling bugs in terminal/cli. Cleaned up some casting issues that surfaced when using dbfile. Removed hardcoded mapping between keys like ^D and ^Z from the cli/terminal class. Added a mechanism to extract the command line history from the terminal class, allowing the application to load/save it. Improved handling of extraneous whitespace in cli. When daemon::daemonize() was called without a delayed exit setting, stdin/stdout/stderr were not closed properly, leading to terminal leakage. Fixed a memory leak error in the dictionary<kind> template class.
0.8.13 Fri Jan 05 2007	Internalized md5 crypt can now generate BSD-style MD5 hashes natively. Fixed a timing bug in class conditional. The XML parser is much stricter now and will complain about such things as unbalanced tags. More forgiving behavior can still be requested through a global flag. Added leak detection to the management of memory involving temporary objects. Added perthread<kind> template class to wrap the behavior of keeping thread-local copies of instances of a class. Improved resolving of the location of the application bundle directory. Executables will look for a function called grace_init and call this before creating the main application object, allowing you to override default settings for the runtime at the earliest opportunity. Moved lots of default limits and sizes into a static tree of global namespaces/variables that can be altered at runtime. Added 'Serialized Hierarchical Object eXchange' (SHOX) as a method for storing varlue objects in a compact binary format that is endian-safe. Improved behavior of value objects in const context that are cast to a string. Improved handling of escaped data inside XML attributes. Migrated inter-thread event messaging to a specialty class eventq. Improved usability of the array and dictionary templates. Added an exception base class, making it easier to catch targeted exceptions. Added sub-project libdbfile for accessing database files through an easy interface. Currently supports gdbm and berkeleydb version 4. Added a template iterator class to improve the foreach macro. Added VT100 terminal emulation for keyboard input, including classes to set up a fully fledged assistive IOS-style command line interface with complex syntaxes and callbacks. Moved default values from macro-definition to initialized globals. Runtime changes to these defaults can be achieved by defining an optional init function in your code that gets executed before the application object is created. This is in preparation for the 0.9 series that will be built as a shared library (which also implies we need to focus on stabilizing the API/ABI at that point). Fixed a bug in the retained copy-constructor of string. Added exclusivesection (var) {...}, sharedsection (var) and unprotected (var) {...} macros to access values wrapped inside a lock<> template with a clear indication of the scope of the lock. Cleaned up test system. Added caseselector { incaseof() : ...; defaultcase : ...; } macros that allow switch/case with string keys. Created new baseclass memory::retainable, uses more efficient preallocation for temporary return values. Added "returnclass (type) name retain" macro to make it easy to create return values that can be passed as a pointer but can be accessed with a reference throughout the function. Added nifty foreach macro to visitor.h. Moved codebase to a mercurial repository. Allow xml schemas to define the tag type of an xml node as implied by the object's datatype. <danny@illogic.nl> Overhauled class timestamp, phase 1. Added test scenarios. Cleaned up value_ascii (formatting code was bug-ridden). Added the smtpd class and friends for implementing an SMTP daemon with flexible delivery handling. Fixed proper handling of <grace.help/> and <grace.default/> for runoptions. Default runoption handler for --help. Added new class currency, representing fixed point arithmetic with 3 decimals accuracy. Added a currency internal type to the value class. Fixed export of floating point numbers. Added timeofday class for microsecond measurements and higher precision 'wait until' functionality. Submitted by <danny@illogic.nl>. Improved handling of PHP serialized arrays. Fixed handling of SSL cipher exchange for connections that act non-blocking. Fixed buffer allocation strategy for SSL initialization. Fixed handling of timeout conditions in SSL context. Fixed handling of timeout conditions in HTTP/1.1 chunked- encoding transfers. Added string::chomp(). Added string::replace(). Added <xml.option.rootclass/> specification to the xml.schema language. Added smtpsocket class for sending email through SMTP. The file class now recognizes an optional iocodec member object that can be linked to handle transparent coding of the data stream. Integrated the MatrixSSL library as part of the optional grace-ssl component, which offers the sslclientcodec, sslsocket and httpssocket classes (server classes will follow, as well as proper certificate checking). The mkproject utility now creates better project templates for application or daemon based programs. The daemon::log() function emits to stdout when the application has not yet been daemonized. The new configdb template class makes it easier to handle configuration and live configuration changes. By binding methods of your application class to different paths of your configuration file, you can easily translate a configuration layout to an object hierarchy and keep track of changes. Integrated new sval utility for validating xml.schema and grace.validator.
0.8.12 Fri Sep 2 2005	XML schema support for union objects. XML schema support for wrapping/unwrapping chained object hierarchies into a single object. XML schema support for implicit arrays according to object class. The httpd class would not return a content-length for a reply body with zero length. Added more operators to string/statstring/value to deal with const/non-const. Added class validator for handling data-validation. Added schema specifics for the <grace.validator> objects. Fixed strutil::pad() to not crop data if the string is longer than the padding size. That stunt interfered with the possiblity of jumping up and down in a binary stream through the string::binputfoo() methods. Added support for encoding value objects to serialized PHP arrays (with or without attributes) through string::phpserialize() and string::phpdeserialize(). The "home:", "var:", "log:" and "run:" aliases were screwed up on initialization. Now they're not, so the checkpid()/writepid() stuff in daemon actually works:). If a null character (or no second argument) is passed to strutil::splitquoted, the split will be on the basis of any whitespace character. This was necessary to make strutil::xmlreadtag() understand tags where attributes only have tabs inbetween.
0.8.11 Mon Jul 18 2005	GCC4.0 compatibility fixes. Added str::cutatlast, cutafter, cutafterlast. Added str::copyuntil, copyuntillast, copyafter, copyafterlast. Added doxygen documentation to all classes. Added file::writeln. Added class serverpage, a httpdobject that pre-parses HTTP POST variables. XML schemas can now defina a doctype inside the options section. The cmdtoken_root class is now natively called scriptparser.
0.8.10 Sat May 15 2005	Bugfix: tcpsocket::connect() was using a thread-unsafe method for resolving the hostname. Bugfix: the reference counting of the stringref database tracked for statstring objects was not entirely threadsafe, this screwed up during garbage collection. Datablocks allocated for a string now contain a thread-specific reference. In situations where a string was copied to several threads, an issue could rise where the stringref got decreased in ways that are not 100% threadsafe. The value class now uses a somewhat less intensive power-of-two allocation scheme for arrays. This saves on reallocations. New class ringbuffer implements a fixed-size ringbuffer for character data. File i/o now takes place through a ringbuffer instead of a string object. Especially in situations where lots of bandwidth passes a file or tcpsocket this operation is now much speedier. Added a readuntil() method to the file class, allowing for convenient streaming of file/socket data up to a provided marker. Bugfix: value::rmval() had some issues under duress. Bugfix: string::pad() didn't work properly A string object can now be initialized with a defined initial allocation size. A checksum64() function is added, this is a fairly quick hash from a string to a unique 64 bit integer. It has a very low tested collision rate against message-ids. A non-blocking version of file::read() was added as well as a file::waitforline() method that allows for a timed wait for a terminated line (<LF> or <CRLF>). Line reading methods of the file class now have a maximum length parameter. A tcpsocket yields to false if it is not initialized. Added tcplistener::tryaccept() method for a timed wait on a new connection.
0.8.9 Mon Feb 14 2005	Applications now actually work if they are in your $PATH and you invoke them without an explicit path. The startup code only checked the apps: alias but never the tools: alias which is where the old $PATH is hiding. Added a ::tryaccept method to tcplistener which allows for a timeout. The httpd class now has a ::shutdown method that gracefully exits all threads after handling any outstanding connections. New default aliases var:, state:, log: and run: implement the /var hierarchy. All these can be overruled with $PATH_VAR &c. The daemon class now creates a proper pid-file on daemonize() and will not start if an earlier copy is already running. All logfiles (coming out of daemon and httpdlogger) allow for automatic logrotation. Created a new grace/defaults.h to collect all those more or less arbitrary integer defaults for things like buffer sizes. Created a test/ subtree with some unit tests.
0.8.8 Sun Oct 31 2004	Resurrected the dictionary template class into working condition. Added an array template class. Added a more convenient name 'scriptparser' for the cmdtoken_root class. There is also a grace/scriptparser.h header file. The httpd class can now incorporate the scriptparser class for handling documents with a provided extension. A httpdfiletypehandler base class allows for specific handling of certain filetype extensions. The http class can now deal with chunked encoding. Added string::cutatlast methods Fixed some compilation issues with SGI MIPSPro compilers
0.8.7 Mon Sep 6 2004	Added a timestamp class that can assist in bridging various date formats. The stringrefdb was a mess. It now retains values for a while, only if the grand total of abandoned nodes amounts to more than 32K will the reaper be invoked. I'm not a big fan of garbage collection, but key data tends to get reused a lot and immediately flushing nodes puts an unreasonable strain on the treelock. The XML schema language now supports the concept of containers that can adequately morph seriously weird tag-wrapping concepts like apple's plist and xmlrpc easy. The XML schema now has a concept for nodes that indicate a boolean that is set to either true or false, as used for plist bool types (you have to wonder why they chose to be compact and elegant _just_ for this _one_ type). For reasons stated above, value::*plist is now depcrecated and is now just an attempt to load the file "schema:com.apple.plist.schema.xml" as a schema followed by a load/save/from/toxml with that schema. Specific string classes in an XML schema can now contain base64-encoded data. Path volumes now support entries that can have a low priority but are skipped by the right-to-left considerations of transw(). This allows for the "conf:" volume to point to 'app:Contents/Configuration Defaults' as a source of last resort without defaulting to that directory when writing changed preferences to disk. Implemented upstream changes in tina in the configure script to help out compilation on more platforms. The lock::trylockw() and lock::trylockr() methods now have an optional timeout argument in seconds. Added httpd.cpp/httpd.h implementing a multithreaded daemon that can easily be embedded into other programs that wish to interface with the outside world with a http daemon. By creating a chain of classes, the exact functionality needed can be added. Added support for sendfile() to class tcpsocket. On platforms that do not support this system call (currently meaning every OS but linux) this will trigger a normal read()/write() cycle. Added a filesystem::size (filename) method. Value attributes are now themselves value objects when asked for through operator(). Thus ends the era of braindead string conversions on attributes within a class that itself can deal perfectly well with other data types. Fixed a metric buttload of errors dealing with statstring objects that contained a null-value. Individual threads were already spawned with their flags set to ignore SIGPIPE. This signal is now deferred globally. The
0.8.6 Sat Aug 28 2004	Fixed memory leaks in xmlschema. Fixed memory leaks in visitor. Fixed memory leaks in httpsocket. Fixed bugs in string. Fixed up leaky nature of regexpression.
0.8.5 Sat Aug 21 2004	Got the loading of configuration files through conf: right for a change. Fixed configure scripts for proper rpm builds. Added a mkconf util that will install the default configuration in the proper place. Fixed compiling issues with FreeBSD and NetBSD. Added peer_name and peer_host to tcpsocket. Added more robustness to httpsocket.
0.8.4 Sun Aug 1 2004	Added support for Unix Domain sockets to tcpsocket. Added passing of credentials/filedescriptors to tcpsocket. Fixed proper implementation of grace.runoptions in the application class. Added a 'daemon' application class for service application models. Includes a background log thread that can relay events to a file or unix syslog. Fixed thread implementation and event passing between thread objects. Added a default file 'resources.xml' to be loaded into the application::rsrc value object. The daemon class uses this to determine log dispatching. Ideally, the definition of commandline arguments should move to this file as well. Currently the file operates without a schema.
0.8.3 Tue May 11 2004	Added methods for parsing windows-style INI files in various iterations of this "standard". Cleaned up some inlining to reduce library size with 300K. Added mkproject/mkapp tools for creating project directories and application bundles. Split up some files to ease up compilation.
0.8.2 Thu May 06 2004	XML schema files now have a section that can define namespaces by their URI and actions to perform when encountering tag types or attribute names that have a namespace prefix corresponding to an xmlns-definition with that URI. The value class can now destinguish child nodes with a key from those without much easier; Unkeyed items are always inserted in front of keyed items. A value::arraysize() method returns the count of unkeyed items. Given an arraysize() as of 4 for value foo, it is a given that foo[0]...foo[3] are unkeyed children. Merged the dictionary template class, to be used for keeping a container of keyed objects of any class. Fixed XML parser to not break when encountering an XML string like <foo></foo>.
0.8.1 Mon Mar 29 2004	New methods in value to import and export CSV-format files into/from two-dimensional arrays (optionally with named keys). This is not entirely perfect yet with regard to native encoding of special characters. Cleaned up some mess that stops cygwin's gcc from yelling at me. Implemented an atoll replacement for the same purpose.
0.8.0 Fri Jan 9 2004	Extra value-types: bool, unsigned, long, ulong, short, ushort, char, uchar, date Visitor template class defines a way to browse tree data objects without resorting to manual pointer-chasing. Support for "tdict"-style text schemas has been replaced with the "xml.schema" schema-definition syntax Support for recursion in volume paths, ie: PATH_SCHEMAS=app\:schemas:etc\:schemas Can now interact with DAAP-style binary XML streams, with definitions within the XML schemas Default scheme to start a GRACE application on a Unix system now uses a bundle directory combined with a softlink, ie: MyApplication -> MyApplication.app/exec MyApplication.app/ .:<mime> system/application-bundle exec -> code/linux.i386/exec icon/ 64.png schemas/ nl.madscience.schemas.myapp.defaults.xml defaults/ nl.madscience.defaults.myapp.xml This makes it relatively easy to define schemas that determine the layout of the data when it is serialized to XML or CXML. myValue[-1] now returns the last child in the array
0.7.2 Fri Oct 24 2003	Split up the value class implementation over several files. The XML functionality of the value class has been greatly enhanced, including automatic translation between keys and tag types on load and save. Metadata moved to dotfiles. Implement "app:" volume pointing to the directory that contains application resources.
0.7.1 Fri Sep 12 2003	Added a valueindex class as a means of indexing a value array by an arbitrary attribute or child value. The application class now picks up all environment variables.
0.7.0 Sat Aug 30 2003	The value class can now read and write XML files using an extended version of the Apple plist DTD. UDBC has been changed to return an array of records instead of a record of arrays. Record keys are now statstring objects, making this possible without memory waste. The main() loop is now defined in the library. This means today's message is: Derive the application class or die. Added fs::load() and fs::save() for reading data directly to a string object.
0.6.4 Sun Jun 29 2003	Created a new class statstring, intended for referencing large number of constant strings containing a high number of duplicates. The value class now uses statstring for its label, making it practical to use an array of values-acting-as-structs as a return type without wasting space on $ARRAYSIZE times the allocation overhead of the label names.
0.6.3 Tue Jun 10 2003	Added db.insert_id() method and backend handling to save on stupid-looking select last_insertid() queries. Added pathvolume parsing for locating database driver module.
0.6.2 Fri Feb 28 2003	Added extra parsing of cmdtoken templates with support for function calls through pseudo-tags. Fixed minor bug
0.6.1 Wed Feb 26 2003	Added cmdtoken handlers as a replacement for the existing cgitemplate class, added benefit is loop-control and conditionals from within the parsed template. Makes it easier to generate row-output for queries, since the template can now better control its own dataflow. Added kernel.time.now() to system.h
0.6.0 Sun Feb 23 2003	Added loads of infrastructure to fs, including fs.ls() with preliminary support for both extension- based mimetypes and inherent mimetypes through generated softlinks. Path Volumes with overlays now work correctly for all file operations.
