* http: initial rewrite using ringbuffer + pthreadsEric Wong2008-06-301-556/+793
| | | | | | | | | | | | | | | | | This institutes the usage of a separate thread to buffer HTTP input. It is basically practice code for using the ringbuffer code which I plan on reusing for the OutputBuffer as well as further input buffering for disk (networked filesystems over WAN, laptops on battery, etc). Each readFromInputStream() call on an HTTP stream can take several seconds to complete, short reads are avoided. A single-threaded solution for systems supporting large enough SO_RCVBUF values should also be possible and will likely be done in the future; but this lock-free(except when full/empty) ringbuffer is cool :) git-svn-id: https://svn.musicpd.org/mpd/trunk@7393 09075e82-0dd4-0310-85a5-a0d7c8717e4f

* networking: more assertions and cleanups to size_t/unsigned changesEric Wong2008-03-261-31/+33
| | | | | | | | | | | | Basically, I don't trust myself nor Max to not have bugs in our code when switching over to unsigned types, so I've added more assertions which will hopefully trip and force us to fix these bugs before somebody can exploit them :) Some cleanups for parameter parsing using strtol and error reporting to the user. Also, fix some completely garbled indentation in inputStream_http.c git-svn-id: https://svn.musicpd.org/mpd/trunk@7209 09075e82-0dd4-0310-85a5-a0d7c8717e4f
* use size_tMax Kellermann2008-03-261-19/+18
| | | | | | | | When dealing with in-memory lengths, the standard type "size_t" should be used.

* Cleanup #includes of standard system headers and put them in one placeEric Wong2008-01-031-14/+1
| | | | | | | | | | | | | 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

* inputStream_http: signal the server to close after all requestsEric Wong2007-09-081-1/+1
| | | | | | | | | | | | | | We want the partial content goodies of HTTP/1.1 without requiring persistent connections. Persistent connections across multiple HTTP requests don't really help in the case of MPD, either, because our content is usually big and heavy. Note: this puts MPD at the hands of the server to correctly close() the TCP connection we're using. If we connect to a rogue server that keeps the connection alive even when request not to, we'll spin :( However, encountering such a server is very unlikely... git-svn-id: https://svn.musicpd.org/mpd/trunk@6867 09075e82-0dd4-0310-85a5-a0d7c8717e4f

* inputStream_http: cleanup GET request code (finishHTTPInit)Eric Wong2007-02-191-29/+29
| | | | | | | | | | | | | | | | | Avoid unnecessary memset to zero, snprintf always puts a trailing '\0'. We also have no need to subtract one from the buffer we're snprintf-ing it to. We also check the return value of snprintf to ensure it's not too long. I have a feeling we might as well avoid snprintf altogether so we don't have to worry about buffer sizing/stack overflow and just do a bunch of write(2)s, letting Nagle sort it out... Also, centralize some of the exit error handling in with goto. This makes the code a bit more consistent and maintainable as well as reducing code and binary size. git-svn-id: https://svn.musicpd.org/mpd/trunk@5395 09075e82-0dd4-0310-85a5-a0d7c8717e4f

* Replace strdup and {c,re,m}alloc with x* variants to check for OOM errorsEric Wong2006-08-261-20/+20
| | | | | | | | | | | | | | | | | | | 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
* remove clumsy strncpy useEric Wong2006-07-301-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | strncpy isn't really safe because it doesn't guarantee null termination, and we have had to work around it in several places. strlcpy (from OpenBSD) isn't great, either because it often leaves errors going unchecked (by truncating strings). So we'll add the pathcpy_trunc() function with is basically strlcpy with a hardcoded MAXPATHLEN as the limit, and we'll acknowledge truncation since we only work on paths and MAXPATHLEN should be set correctly by the system headers[1]. file-specific notes: inputStream_http: eyeballing the changes here, it seems to look alright but I haven't actually tested it myself. ls: don't even bother printing a file if the filename is too long (and when is it ever?) since we won't be able to read it anyways. metadataChunk: it's only metadata, and it's only for showin the user, so truncating it here souldn't be a big issue. memset to zero in init is unecessary, so lets not waste cycles [1] - If the system headers are screwed up, then we're majorly screwed regardless of what we do :x git-svn-id: https://svn.musicpd.org/mpd/trunk@4491 09075e82-0dd4-0310-85a5-a0d7c8717e4f
