database to preserve the meaning of log messages in old databases
in case of renumbering... but these tables were never used, and
the tables used to create them were, in fact, out of date and
inconsistent with the range of operations now supported. Remove
the vestigial remains of the never-implemented feature.
Also, update .gitignore to stop git from complaining about some
more generated files.

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.

one device to another, for instance.

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.

Add PSEUDO_BINDIR, PSEUDO_LIBDIR, and PSEUDO_LOCALSTATEDIR to allow for more
easy customization of PSEUDO components at run-time. If these are not set
they will be automatically generated based on the existing PSEUDO_PREFIX path.
PSEUDO_BINDIR = PSEUDO_PREFIX /bin
PSEUDO_LIBDIR = PSEUDO_PREFIX /lib
PSEUDO_LOCALSTATEDIR = PSEUDO_PREFIX /var/pseudo

When moving a directory, pseudo performs the following sequence: stat
old, unlink new, link old and then rename. When linking a file, pseudo
first makes sure the file does not already exist in the database and
does an unlink. So the full sequence was stat old, unlink new, link
old ( unlink old, unlink contents of old, relink old ), rename. The
fix removes the unlinking of the contents of old.

Address a couple of compiler warnings, add a couple of signals to the
list of caught signals, etcetera.
|
|
pdb_history was overloaded as a delete function. Separated this
out into a query-builder and a pair of functions to use it, which
makes it cleaner.

Stop vacuuming the logs database under normal usage -- it's expensive
and slow, and not useful.
Make link(2) "correctly" (following Linux, rather than POSIX) link
to a symlink rather than to the file the symlink links to.

When you rename across devices, inode can change. Until now,
pseudo had no tools for handling a change in inode, but this
is clearly a legitimate case.

It is possible for the database to get out of sync with the
filesystem. Detecting this after the fact can be hard. Provide a
hook for requesting a check.
Also merge in some LD_LIBRARY_PATH fixes.

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.

This allows us to track execution, although the tracking for it
requires some additional thought -- the basic assumption is that we
don't want to canonicalize names into the chroot() directory, but
since all the filename canonicalization assumes that we want this,
that will take some sneaking. It's a little useful as is, though,
so I'm running with it.

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.
|
|
None of them seem to have been genuine problems, but it's prettier now,
and some were questionable.
|
|
Add chroot() and a large number of things needed to make it work.
The list of intercepted calls is large but not exhaustive.
