* const pointersMax Kellermann2008-09-021-4/+4
| | | | Yet another patch which converts pointer arguments to "const".
* tag: try not to reallocate tag.items in every add() callMax Kellermann2008-09-021-1/+15
| | | | | | | | | | | | | | | | If many tag_items are added at once while the tag cache is being loaded, manage these items in a static fixed list, instead of reallocating the list with every newly created item. This reduces heap fragmentation. Massif results again: mk before: total 12,837,632; useful 10,626,383; extra 2,211,249 mk now: total 12,736,720; useful 10,626,383; extra 2,110,337 The "useful" value is the same since this patch only changes the way we allocate the same amount of memory, but heap fragmentation was reduced by 5%.
* tag: added a pool for tag itemsMax Kellermann2008-09-021-1/+2
| | | | | | | | | | | | | | | | | | | The new source tag_pool.c manages a pool of reference counted tag_item objects. This is used to merge tag items of the same type and value, saving lots of memory. Formerly, only the value itself was pooled, wasting memory for all the pointers and tag_item structs. The following results were measured with massif. Started MPD on amd64, typed "mpc", no song being played. My music database contains 35k tagged songs. The results are what massif reports as "peak". 0.13.2: total 14,131,392; useful 11,408,972; extra 2,722,420 eric: total 18,370,696; useful 15,648,182; extra 2,722,514 mk f34f694: total 15,833,952; useful 13,111,470; extra 2,722,482 mk now: total 12,837,632; useful 10,626,383; extra 2,211,249 This patch set saves 20% memory, and does a good job in reducing heap fragmentation.
* tag: converted tag_item.value to a char arrayMax Kellermann2008-09-021-2/+2
| | | | | | | The value is stored in the same memory allocation as the tag_item struct; this saves memory because we do not store the value pointer anymore. Also remove the getTagItemString()/removeTagItemString() dummies.
* tag: converted MpdTag.items to a pointer listMax Kellermann2008-09-021-1/+1
| | | | | | This prepares the following patches, which aim to reduce MPD's memory usage: we plan to share tag_item instances, instead of just their values.
* tag: moved code to tag_id3.cMax Kellermann2008-09-021-12/+0
| | | | | The ID3 code uses only the public tag API, but is otherwise unrelated. Move it to a separate source file.
* tag: converted tag_add_item() to an inline functionMax Kellermann2008-09-021-2/+5
|
* tag: renamed functions, no CamelCaseMax Kellermann2008-09-021-14/+14
|
* tag: renamed MpdTag and MpdTagItem to struct mpd_tag, struct tag_itemMax Kellermann2008-09-021-15/+15
| | | | | Getting rid of CamelCase; not having typedefs also allows us to forward-declare the structures.
* const pointersMax Kellermann2008-08-311-1/+1
| | | | The usual bunch of pointer arguments which should be const.
* unsigned integers and size_tMax Kellermann2008-08-311-1/+2
| | | | | Use "unsigned int" whenever negative values are not meaningful. Use size_t whenever we are going to describe buffer sizes.
* converted MpdTagItem.type to an enumMax Kellermann2008-08-301-16/+18
| | | | | Don't use CPP macros when you can use C enum... this also allows better type checking.
* fix -Wconst warningsMax Kellermann2008-02-051-1/+1

* Cleanup #includes of standard system headers and put them in one placeEric Wong2008-01-031-3/+0
| | | | | | | | | | | | | This will make refactoring features easier, especially now that pthreads support and larger refactorings are on the horizon. Hopefully, this will make porting to other platforms (even non-UNIX-like ones for masochists) easier, too. os_compat.h will house all the #includes for system headers considered to be the "core" of MPD. Headers for optional features will be left to individual source files. git-svn-id: https://svn.musicpd.org/mpd/trunk@7130 09075e82-0dd4-0310-85a5-a0d7c8717e4f

* interface/connection malloc reductions from mpd-keEric Wong2006-07-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch massively reduces the amount of heap allocations at the interface/command layer. Most commands with minimal output should not allocate memory from the heap at all. Things like repeatedly polling status, currentsong, and volume changes should be faster as a result, and more importantly, not a source of memory fragmentation. These changes should be safe in that there's no way for a remote-client to corrupt memory or otherwise do bad stuff to MPD, but an extra set of eyes to review would be good. Of course there's never any warranty :) No longer do we use FILE * structures in the interface, which means we don't have to allocate any new memory for most connections. Now, before you go on about losing the buffering that FILE * +implies+, remember that myfprintf() never took advantage of any of the stdio buffering features. To reduce the diff and make bugs easier to spot in the diff, I've kept myfprintf in places where we write to files (and not network interfaces). Expect myfprintf to go away entirely soon (we'll use fprintf for writing regular files). git-svn-id: https://svn.musicpd.org/mpd/trunk@4483 09075e82-0dd4-0310-85a5-a0d7c8717e4f
