- "lzma alone" is superseeded by XZ but it's used by Suse and Mandriva
distros so it's nice to have as it doesn't need much, only open differs
from XZ
- rpmlib() dependency versions are an uuuuuuuugly mess here: Suse used
"PayloadIsLzma = 4.4.2-1" so that's what we provide to be most compatible
(hopefully). Built packages require "PayloadIsLzma <= 4.4.6-1" however
to be compatible with Mandriva 2008.0. Did I already say it's ugly?
- Based on similar patch in Mandriva by Per Øyvind Karlsen, but avoiding
unnecessary renames in rpmio
- what we support now in payloads is XZ, not the former LZMA format, rename
user- and header-visible parts to match this
- rpmlib(PayloadIsXz) dependency versioned 5.2-1 to avoid unnecessary
incompatibility with what rpm5 has and what Mandriva is already using
- only provide the rpmlib dependency if actually built with xz support
- rpmFileIsCompressed() attempts to guess the magicless old lzma format
by file suffix, so it can handle both right now
- allow to run helper programs to check:
- generated SRPM
- each generated RPM after it is successfully written
- whole successfully written binary package set
- it is possible to use it for sanity checks
- only use 64bit variants for packages that actually need it to avoid
breaking compatibility when not needed
- old rpm will bail out "cleanly" (with an obscure error message) if
the 32bit size tags are missing but at least it doesn't crash...
- it'd be far nicer to be able to append single strings to string arrays
through rpmtdFromString() but it'll require some interesting hackery
in header.c
- use temporary const char* pointer where necessary to convert to
const char ** compatible type before passing to rpmtdFromStringArray()
- heavy on asserts() for now to catch out any problems
- sigtags can't use rpmtdFromFoo() as the tag numbers collide with the
regular tag table and would cause failures if we tried
- cpio "new" ascii format limits individual files to UINT32_MAX, no such
limit on the entire archive though
- RPMSIGTAG_PAYLOADSIZE is 32bit type atm, assert that the archive size
fits to UINT32_MAX despite internal presentation being larger
- FD_t limits the real archive to rpm_off_t still
- Actually use mkstemp() for creating the temp file and return a FD_t
dupped from the file descriptor returned by mkstemp().
- Simplify the interface while at it.
- Change callers for the new interface.
- Yes we now require mkstemp() to work, mkstemp() is in POSIX.1-2001 and
this is year 2008...
- Horrible kludgery to get the isa names and bits into platform specific
macros from installplatform script. That beast needs to die. I mean really
- In build, add provides: name(isa) = evr automatically when it makes
sense (similarly to name = evr provides). ISA consists of ISA name and
bitness (or wordsize). This can be used to correctly
express multilib dependencies without resorting to (expensive!) file
dependency kludges, eg for dlopen()'ed libraries where automatic
dep extraction doesn't force dependency on 32bit vs 64bit version, you
can now use:
Requires: foo-plugin%{?_isa}
This expands to foo-plugin(x86-32) for i?86 packages, foo-plugin(x86-64)
to x86_64 etc, and permits spec to be shared with older distros which
don't have ISA provides.
- The same could be expressed with "canon arch" just as well, but
using the ISA to differentiate from %_arch and the like:
eg i386 could be used instead of x86-32 but it's overloaded with meanings
(the actual i386 processor vs i386 compatible cpu family etc)
- put some consistency into include ordering
- everything (apart from bits missed ;) is now ordered like this
1. "system.h"
2. other system includes
3. rpm public headers
4. rpm private headers
5. "debug.h"
