2019-05-15Add SPDX-License-Identifier: LGPL-2.1-only to filesRichard Purdie25-12/+49
This adds SPDX license headers to all source files in pseudo so license identification models current best practise. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2018-01-16Handle long lines in /etc/groupSeebs3-9/+68
This allows the pseudo /etc/group to contain extremely long lines, e.g. when a group has a lot of members. Without this, chown and chgrp fail for group names that occur after such long lines.

2013-06-25Change debugging to use flags rather than levelsPeter Seebach1-1/+1
This is a moderately intrusive change. The basic overall effect: Debugging messages are now controlled, not by a numeric "level", but by a series of flags, which are expressed as a string of letters. Each flag has a single-letter form used for string specifications, a name, a description, a numeric value (1 through N), and a flag value (which is 1 << the numeric value). (This does mean that no flag has the value 1, so we only have 31 bits available. Tiny violins play.) The other significant change is that the pseudo_debug calls are now implemented with a do/while macro containing a conditional, so that computationally-expensive arguments are never evaluated if the corresponding debug flags weren't set. The assumption is that in the vast majority of cases (specifically, all of them so far) the debug flags for a given call are a compile-time constant, so the nested conditional will never actually show up in code when compiled with optimization; we'll just see the appropriate conditional test. The VERBOSE flag is magical, in that if the VERBOSE flag is used in a message, the debug flags have to have both VERBOSE and at least one other flag for the call to be made. This should dramatically improve performance for a lot of cases without as much need for PSEUDO_NDEBUG, and improve the ability of users to get coherent debugging output that means something and is relevant to a given case. It's also intended to set the stage for future development work involving improving the clarity and legibility of pseudo's diagnostic messages in general. Old things which used numeric values for PSEUDO_DEBUG will sort of continue to work, though they will almost always be less verbose than they used to. There should probably be a pass through adding "| PDBGF_CONSISTENCY" to a lot of the messages that are specific to some other type.
2011-03-25Merge in ports workPeter Seebach26-0/+551
This is a spiffied-up rebase of a bunch of intermediate changes, presented as a whole because it is, surprisingly, less confusing that way. The basic idea is to separate the guts code into categories ranging from generic stuff that can be the same everywhere and specific variants. The big scary one is the Darwin support, which actually seems to run okay on 64-bit OS X 10.6. (No other variants were tested.) The other example given is support for the old clone() syscall on RHEL 4, which affects some wrlinux use cases. There's a few minor cleanup bits here, such as a function with inconsistent calling conventions, but nothing really exciting.
