* gcc: define mpd_sizeof_str_flex_arrayEric Wong2008-10-121-0/+5
| | | | | | This can save a few bytes here on newer gcc and there and will hopefully make it more obvious what we're doing with that last struct element
* gcc.h: fix compilation with !(gcc >= 3)Eric Wong2008-01-271-0/+1

* gcc.h: support mpd_fprintf__, with arguments shifted even further rightEric Wong2008-01-261-0/+1
| | | | | This will be used to check errors in command.c git-svn-id: https://svn.musicpd.org/mpd/trunk@7148 09075e82-0dd4-0310-85a5-a0d7c8717e4f

* Replace strdup and {c,re,m}alloc with x* variants to check for OOM errorsEric Wong2006-08-261-1/+0
| | | | | | | | | | | | | | | | | | | I'm checking for zero-size allocations and assert()-ing them, so we can more easily get backtraces and debug problems, but we'll also allow -DNDEBUG people to live on the edge if they wish. We do not rely on errno when checking for OOM errors because some implementations of malloc do not set it, and malloc is commonly overridden by userspace wrappers. I've spent some time looking through the source and didn't find any obvious places where we would explicitly allocate 0 bytes, so we shouldn't trip any of those assertions. We also avoid allocating zero bytes because C libraries don't handle this consistently (some return NULL, some not); and it's dangerous either way. git-svn-id: https://svn.musicpd.org/mpd/trunk@4690 09075e82-0dd4-0310-85a5-a0d7c8717e4f
* No code change, just add headersAvuton Olrich2006-07-311-0/+18

* commandError() cleanups, fixup gcc checksEric Wong2006-07-301-5/+5
| | | | | | | stripped binary size reduced by 9k on my machine from making commandError a function. We'll print out error messages slightly slower before, but the smaller binary is more than worth it. git-svn-id: https://svn.musicpd.org/mpd/trunk@4488 09075e82-0dd4-0310-85a5-a0d7c8717e4f
* interface/connection malloc reductions from mpd-keEric Wong2006-07-301-0/+50
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
