dd: use a more portable definition of O_FULLBLOCK2009-03-20T14:16:50ZEric Blakeebb9@byu.net2009-03-19T19:14:26Zurn:sha1:0b47305caa39c0b11f0488f0cc115fd6b09f7922
* src/dd.c (O_FULLBLOCK): Compute its value without using a 180KB
macro. This avoids triggering a compilation failure with HP-UX's cc.

dd: Better handle user specified offsets that are too big2009-01-28T15:14:57ZPádraig BradyP@draigBrady.com2008-11-20T10:28:31Zurn:sha1:460ebb078ed7bf249af745d8725d6c37e7f15b57
Following are the before and after operations for seekable files,
for the various erroneous offsets handled by this patch:
skip beyond end of file
before: immediately exit(0);
after : immediately printf("cannot skip to specified offset"); exit(0);
skip > max file size
before: read whole file and exit(0);
after : immediately printf("cannot skip: Invalid argument"); exit(1);
seek > max file size
before: immediately printf("truncate error: EFBIG"); exit(1);
after : immediately printf("truncate error: EFBIG"); exit(1);
skip > OFF_T_MAX
before: read whole device/file and exit(0);
after : immediately printf("cannot skip:"); exit(1);
seek > OFF_T_MAX
before: immediately printf("truncate error: offset too large"); exit(1);
after : immediately printf("truncate error: offset too large"); exit(1);
skip > device size
before: read whole device and exit(0);
after : immediately printf("cannot skip: Invalid argument"); exit(1);
seek > device size
before: read whole device and printf("write error: ENOSPC"); exit(1);
after : immediately printf("cannot seek: Invalid argument"); exit(1);
* NEWS: Summarize this change in behavior.
* src/dd.c (skip): Add error checking for large seek/skip offsets on
seekable files, rather than deferring to using read() to advance offset.
(dd_copy): Print a warning if skip past EOF, as per FIXME comment.
* test/Makefile.am: Add 2 new tests.
* tests/dd/seek-skip-past-file: Add tests for first 3 cases above.
* tests/dd/seek-skip-past-dev: Add root only test for last case above.
maint: ensure dd's computation of O_FULLBLOCK uses all O_ symbol names2008-12-26T11:08:51ZJim Meyeringmeyering@redhat.com2008-12-26T11:00:18Zurn:sha1:0c65638b0fe521a47e72f318edfb12c5b3b850f5
* src/dd.c (O_FULLBLOCK): Use a more uniform initializer, that makes
it easier to extract all O_ symbol names.
* maint.mk (syntax-check-rules): Also search for sc_ rules in cfg.mk.
(sc_root_tests): Ensure that this rule sets $diff.
* cfg.mk (sc_dd_O_FLAGS): New rule.
dd: add support for opening files in Concurrent I/O (CIO) mode2008-12-26T09:57:05ZMatt Hardenmatth@mindspring.com2008-12-22T04:06:16Zurn:sha1:5c065bb0cb979dff21c474c0ff45b0c9013791d4
* src/dd.c (O_CIO): New flag.
* src/dd.c (O_FULLBLOCK): Add O_CIO to the list of flags that
O_FULLBLOCK should be greater than.
* src/dd.c (flags): Give the name "cio" to the new O_CIO flag, mirroring
the treatment of O_DIRECT.
* src/dd.c (usage): Add a description of the new flag when it is available.
* doc/coreutils.text (dd invocation): Describe the new flag.
* NEWS: Mention the new feature.
Revert part of "dd: avoid unnecessary memory copies"2008-11-22T09:20:31ZPádraig BradyP@draigBrady.com2008-11-21T22:17:44Zurn:sha1:d5ab05998ca068b9a2e217285b15318ad2e5bdb8
