2008-02-19Oops. I made the Bu::Heap API look like a stack, not a queue, that's beenMike Buland
fixed, and the Bu::ItoHeap is working and tested. Note that when multiple items have the same sort order, they will come out in random order.
2008-02-19I believe this will do the trick. The Bu::Heap class now uses the appropriateMike Buland
allocators for all work, every data type used in a Bu::Heap must support the equals operator and <= or >=, or you need to write your own comparison functor. The heap works as both a min-heap and max-heap, just change out the functor used for camparison, kinda' cool. The print function I'll leave in for a little while, but not in the long run, it just prints a dot graph to stdout. Next up, the Ito version.
2008-02-19Bu::Heap is a real class, it works great, except it doesn't grow right now.Mike Buland
I'm thinking the heap should add one layer to the binary tree each time it grows, which means double+1 each time. The Bu::ItoHeap will be implemented as soon as the rest of Bu::Heap is done. Also, I finally added bu/util.h which is mainly handy template functions like Bu::swap, Bu::min, Bu::max, and Bu::mid. A few more may be added.
2008-02-07Just updated the copyright date.Mike Buland
2007-12-12Corrected some issues with the new trace system. It's now working fine. ↵Mike Buland
It's backword compatible, and the new features are a lot of fun. Since it uses template functions you can add any new variable types to be formatted.
2007-12-12Added the new TRACE test.Mike Buland
2007-12-11Fixed the bu directory, now the code should compile and be usable evenMike Buland
installed. That was odd. Anyway, also set props on the bu, unit, and test directories so that the contents won't be listed on svn status.
2007-12-03Just added the MiniMacro test, it could actually be a unit test without a lot ofMike Buland
effort.
2007-11-30Added some helpers to fstring, and fixed a bug in Bu::Process, it wasn't closingMike Buland
the pipes properly, resulting in the child process going defunct and not dying, it also wasn't buffering properly, it now collects as much data as it can before returning from a read operation.
2007-11-23Added the Process stream class, this will allow us to do some really cool stuffMike Buland
coming up...it's just like popen only cool and managed, and streamey.
2007-11-15Final changes moving to the actually liscense-ified version, plus I fixed aMike Buland
compile error I introduced last commit.
2007-11-15Added liscense info at the front of many, many files. Debating the old files.Mike Buland
2007-11-09Fixed a silly bug in the taf system that interpreted the */ at the end of aMike Buland
comment block as a tag...oops.
2007-11-08Bu::FString now has the functions format, formatAppend, and formatPrepend, allMike Buland
of which use printf style formatting and accept the same parameters as printf.
2007-10-20Made the logger use a uint32_t for it's mask, no more negative confusion. AlsoMike Buland
brought back the formula class with some cool twists, and added a basic stack class, very cute, fast, and little.
2007-10-20Just marked Bu::FString::c_str as deprecated, don't use it, it'll go away later.Mike Buland
2007-10-14Fixed an interesting ideosyncacy in Bu::Hash in a safe way, I should try to doMike Buland
this with the Bu::Archive next. Basically, there's one generic template function that will convert anything that can safely cast to a uint32_t and that supports direct comparisson, and doesn't have it's own override already to be a Hash key, such as char, uint8_t, uint64_t, etc. The Telnet protocol handler does everything I need it too for now, next up for it is escape sequence handling, it would be nice to make this general too, by using the termcap database or something, but there is an ANSI/ISO standard now, I may just go ahead and use that. Also, it looks like it'd be pretty easy to make the canonical mode editing functions be pluggable to facilitate different types of editing, but that can be done down the road as well.
2007-10-03Nothing about function. I added a bunch of docs and re-arranged a bunch ofMike Buland
the existing docs. Taking advantage of some of the cooler extra features of doxygen I've started writing extra how-to pages covering working with sections of the library. Also, I started grouping the classes by function so they show up on the Modules page together, very cute.
2007-09-11Everything seems to work with the new Bu::ItoServer class, it operates very,Mike Buland
very similarly to the Bu::Server class, except that every incoming connection gets it's own thread. This functionality may have to be tuned later, to allow for maintaining a pool of connections as an option, but this is fine for now.
2007-08-26Corrected a bug in the Bu::TafReader, it was getting confused when a stray colonMike Buland
(common in web addresses) was put in the middle of a property list, now it doesn't get confused, it just complains bitterly and refuses to work.
2007-07-18Incorporated a patch contributed by Brandon CS Sanders that allows libbu++ toMike Buland
compile under OSX. So far, no problems with anything else, it looks like build and nango both build without problems, libbu++ is truly becoming a full cross- platform toolkit.
2007-07-11I guess I fixed some list stuff...Mike Buland
2007-07-10Fixed the atom, it wasn't copying from other atoms properly.David
2007-07-09The new logHexDump function seems to work just fine.Mike Buland
2007-07-03Ah, that explains much, I did the big reorg -> trunk move and forgot to commitMike Buland
some things, so here they are, after being manually copied.
2007-06-29The plugger was dying on a HashException it should have caught, and the LoggerMike Buland
now allows you to include extra printf formatting in your fields just like the docs say you can.
2007-06-27The taf system is new and improved. The writer works, we added C++ styleMike Buland
comment blocks, and it retains the order of all nodes.
2007-06-26Fixed a minor bug in FString, and added the Logger and a test...it's cool, andMike Buland
a decent replacement for multilog now that we use runit.
2007-06-19david - got some things compiling on win32 (wine/devc++)David
2007-06-18Added more helper guys to atom, it seems weird, but I think it's ok...Mike Buland
2007-06-18Added the atom class and did some more client work, it will close the socketMike Buland
now when the end has been reached.
2007-06-12Removed the xml test...the xml system is effectively gone.Mike Buland
2007-06-11Few minor tweaks to bzip2, it reports errors now...and there's a bug in odpmMike Buland
that could be in this, but it's going to be hard to tell...
2007-06-10Bunch of maintenence type things. Minor tweaks and the like. The file classMike Buland
has a lot more helper functions and the like, the filters give more info back to the caller, minor updates to taf.
2007-06-09Alright, looks like the bzip2 filter can decompress just fine. It won't try ↵Mike Buland
to compensate for overshooting the end of the compression block yet, which it won't be able to do on streams that don't support seeking...I think I'll make it only try on stop commands, and try to re-use the buffer otherwise...maybe...it's an interesting problem since it *always* overshoots (unless you're really, really lucky...)
2007-06-07The Stream Filter archetecture is finished, it's actually much cooler than IMike Buland
had anticipated, and much cleaner. I'll have to add some documentation to it, because it's not really obvious how any of it fits together from the outset, although I have to say that the bzip2 test program is the easiest general bzip2 compression program I've ever made...it just goes :) Decompression in Bu::BZip2 isn't finished yet, but that's ok, it's coming soon.
2007-06-07The new taf interfaces seem to work just fine, except for saving and that loadedMike Buland
TafNode structures are immutable, it all looks really good. Saving should be a snap, and the immutable part I'm not sure is bad...we'll see what happens. Also, I'm contemplating looking into a way to add "named data structure" support to the Archive at a lower level, then allow it to use a nameing system to apply names to each data structure and then output to any backend that supports naming, like taf, xml, etc.
2007-06-07Except for an excessive amount of debug info, I finally got the delete codeMike Buland
working. Now you can load Taf structures and clean up, you just can't access all of the data inside 100%.
2007-06-06Except for storing the data somewhere, the TafReader is more or less done.Mike Buland
Some more generalizations are in order, then we'll stuff the data somewhere.
2007-06-05Added a basic ringbuffer, it should be nice and quick, but may be bad to useMike Buland
with objects at the moment, still contemplating that one...
2007-05-17As evidenced by my latest test, the Bu::FString copy is actually slower thanMike Buland
the std::string copy by a rather large margin. This seems very odd, so I'm going to do a few tests, the first one is stripping out the FString shared pointer stuff and seeing if that makes an appreciable difference.
2007-05-17Lots of cool new stuff, the Server class actually works for everything exceptMike Buland
actually interacting with clients, and the Client class is almost there, except that it doesn't really do anything yet.
2007-05-15SPtr is now Bu::ified, and the List class now acts the way we think const listsMike Buland
should act, you can't change anything in there. I'm still debating changing the const_iterator to a constIterator, or something else that's more Bu::worthy. Heh, the namespaces are funny...ok...I'm really tired.
2007-05-11Added a list template class, seems to work pretty well for now, I may haveMike Buland
forgotten proper cleanup in the deconstructor, but besides that you can do almost everything you need. I'll make a slist/stack next, probably with the same basic code, just a different structure (not doubley-linked). The xml system from old-libbu++ is almost completely converted, I was going to re-write it, but this seemed easier at first, it may not have been, we'll see. It almost parses everything again, and almost outputs again, and it does use streams now. The FString is partway to doing minimum chunk allocations, so that adding single-characters will be really fast up to the minimum chunk size. I also figured out how to add this optimization without any extra variables taking up space, and it's optional in the template, which is cool. You can specify the size of the blocks (default 256 bytes), if it's 0 then they'll be like the old FString, 1 chunk per operation. The next FString update should be allowing efficient removal from the begining of the string by faking it, and simply moving a secondary base pointer ahead, and then optimizing appends after that fact to simply move the existing data around if you shouldn't have to re-allocate (alla FlexBuf). The final fun addition that I'm planning is a simple switch in the template (boolean) that will switch an FString into a thread-safe mode without changing the interface or anything that you can do with them at all. It may increasing memory usage, but they should still be better than std::strings, and totally thread-safe. The best part of that is that if it's done with a boolean template parameter and if statements that only test that parameter controlling flow, the code that you don't want (threadsafe/non-threadsafe) won't be included at all post-optimization.
2007-05-08Added the TAF format structures and XML format structures, I'm making up TAFMike Buland
(textual archive format), but named it wrong, this seemed easier than redoing it all.
2007-04-26Merged Ito and put it in the BU namespace. I should probably clean up theMike Buland
formatting on the comments, some of the lines wrap, but I'm not too worried about it right now. I also fixed up the doxygen config and build.conf files so that everything is building nice and smooth now.
2007-04-10I did it, the streams don't start with an S now.Mike Buland
2007-04-03The file stream is imported and works, as does our first test, and the newMike Buland
tweaks to archive. The && operator is now a template function, and as such requires no special handling. It could be worth it to check this out for other types, yet dangerous, since it would let you archive anything, even a class, without writing the proper functions for it...we shall see what happens...
2007-04-03The first batch seem to have made it alright. Unfortunately the Archive classMike Buland
isn't done yet, I'm going to make it rely on streams, so those will be next, then we can make it work all sortsa' well.
2007-04-03Ok, no code is left in src, it's all in src/old. We'll gradually move code backMike Buland
into src as it's fixed and re-org'd. This includes tests, which, I may write a unit test system into libbu++ just to make my life easier.
