2012-08-02Remove the _plain thing, use PSEUDO_STATBUF everywhere.Peter Seebach1-7/+0
The _plain thing was added because of clashes between Linux ("struct stat64 for 64-bit file sizes") and Darwin ("struct stat is already 64 bits"). But it turns out not to be enough, because stat will *fail* if it cannot represent a file size, so when something like unlinkat() calls a non-64-bit stat in order to determine whether a file exists, it gets the wrong answer if the file is over 2GB in size. Solution: Continue using PSEUDO_STATBUF, and also provide defines for base_stat() which can be either real_stat() or real_stat64(), etcetera. This eliminates any reason to need the _plain functions. It also suggests that the other real___fxstatat() calls should someday go away because that is an ugly, ugly, implementation detail. As part of testing this, fix up some bitrot which affected Darwin (such as the continue outside of a loop, but inside an #ifdef; that was left over from the conversion of init_one_wrapper to a separate function).
2011-03-25Merge in ports workPeter Seebach1-2/+9
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.
2010-11-30Major shift: All the id_t types have been reworked so that theyPeter Seebach1-14/+2
are generated from text files and templates, making it now (we hope) impossible for the list of strings to get out of sync with the enum.
2010-08-17Draft one effort at making unlink more robust and fixing an obviousseebs1-0/+1
bug in the speculative-unlink operation. The intent is to mark and then confirm or cancel the delete. This removes the quirk where we tried to stash old database entries, which didn't handle directories anyway; "rmdir non-empty-directory" is a bit too common a case to dismiss as unthinkable.
2010-04-26Updates/improvements for loggingPeter Seebach1-0/+4
Send program name (program_invocation_name from glibc) along with the tag. Along the way, restructure the fds/pids/tags arrays to be an array of client structures in pseudo_server, and add the message type to the set of things logged -- logging that a message was a ping is more useful than appending the text "ping" to it. Add support for type and program to pseudolog. Add deletion to pseudolog. Handle usage message formatting when there's an odd number of known specifiers for pseudolog.

2010-03-26Track file open flagsPeter Seebach1-1/+17
This patch adds support for checking whether a file was opened for reading, writing, or both, as well as tracking append flags. It is not very well tested. This is preparation for improved host contamination checking.
