In particular, failure of the external program is detected a lot earlier, which gives much more reasonable error handling. 2009-04-12T05:33:34Z Tim Kientzle kientzle@FreeBSD.org 2009-04-12T05:33:34Z urn:sha1:e2421f76676c33a8de3054504f3ecb9ca3d1ee75 corrections to the Windows support to reconcile differences between Visual Studio and Cygwin. Includes parts of revisions 757, 774, 787, 815, 817, 819, 820, 844, and 886. Of particular note, r886 overhauled the UTF-8/Unicode conversions to work correctly regardless of whether the local system uses 16-bit or 32-bit wchar_t. (I assume that systems with 16-bit wchar_t use UTF-16 and those with 32-bit wchar_t use UCS-4.) This revision also added a preference for wcrtomb() (which is thread-safe) on platforms that support it. 2009-03-07T02:47:04Z Tim Kientzle kientzle@FreeBSD.org 2009-03-07T02:47:04Z urn:sha1:de01c3b1eb13cee76fc0a11545d7bb90ea487047 Refactor the read_compression_program to add two new abilities: * Public API: You can now include a signature string when you register a program; the program will run only on input that matches the signature string. * Internal API: You can use the init() function to instantiate an external program as part of a filter pipeline. This can be used for graceful fallback (if zlib is unavailable, use external gzip instead) and to use external programs with bidders that are more sophisticated than a static signature check. 2009-03-06T05:58:56Z Tim Kientzle kientzle@FreeBSD.org 2009-03-06T05:58:56Z urn:sha1:634fb9dd4872ad89170b514d8c0bf9125bfa0d3e This implements the new generic options framework that provides a way to override format- and compression-specific parameters. 2009-03-06T04:22:34Z Tim Kientzle kientzle@FreeBSD.org 2009-03-06T04:22:34Z urn:sha1:74aced1051fd7b49111cde220c7d12a449ab53e5 object was allocated before we try to use it. 2009-03-05T02:19:42Z Tim Kientzle kientzle@FreeBSD.org 2009-03-05T02:19:42Z urn:sha1:facbbae9f9c0085b9c8ccc26b5c42069f14eb5f1 This is the last phase of the "big decompression refactor" that puts a lazy reblocking layer between each pair of read filters. I've also changed the terminology for this area---the two kinds of objects are now called "read filters" and "read filter bidders"---and moved ownership of these objects to the archive_read core. This greatly simplifies implementing new read filters, which can now use peek/consume I/O semantics both for bidding (arbitrary look-ahead!) and for reading streams (look-ahead simplifies handling concatenated streams, for instance). The first merge here is the overhaul proper; the remainder are small fixes to correct errors in the initial implementation. 2008-12-06T06:45:15Z Tim Kientzle kientzle@FreeBSD.org 2008-12-06T06:45:15Z urn:sha1:b1ff9c25b85752421491eb42f56c4cf65f451f98 This is an attempt to eliminate a lot of redundant code from the read ("decompression") filters by changing them to juggle arbitrary-sized blocks and consolidate reblocking code at a single point in archive_read.c. Along the way, I've changed the internal read/consume API used by the format handlers to a slightly different style originally suggested by des@. It does seem to simplify a lot of common cases. The most dramatic change is, of course, to archive_read_support_compression_none(), which has just evaporated into a no-op as the blocking code this used to hold has all been moved up a level. There's at least one more big round of refactoring yet to come before the individual filters are as straightforward as I think they should be... 2008-09-12T03:53:54Z Tim Kientzle kientzle@FreeBSD.org 2008-09-12T03:53:54Z urn:sha1:6d35d9a6e9aacf7465613823d434f2336a371209 (which always returns an error when invoked) needs its prototype. 2008-06-15T10:45:57Z Tim Kientzle kientzle@FreeBSD.org 2008-06-15T10:45:57Z urn:sha1:936d273c3ae5d1589b5789392b3603bed46af91c programs: * Support platforms that have fork() but not vfork() * Don't write(), select(), or poll() against closed file descriptors
