2012-03-27Allow static sqlitePeter Seebach
Some systems prefer to avoid messing with LD_LIBRARY_PATH as much, and instead link sqlite statically.
2012-03-27Configuration cleanup for OE-core:Peter Seebach
In OE-Core we need to be able to configure for both 32-bit and 64-bit libpseudo libraries. In order to avoid some complex manipulations, we adjust the configure and Makefile to facilitate this. Upstream-Status: Submitted Signed-off-by: Mark Hatle <mark.hatle@windriver.com>
2012-03-27add popen() callPeter Seebach
We weren't trapping popen(), so if environment variables were in an inconsistent state when popen() was called, Bad Things Happened. Add a popen() wrapper. Like a couple of other special cases, is applied even when pseudo is theoretically disabled, and that includes the antimagic case. (But we never use popen() so that's fine.)
2012-02-06The O_LARGEFILE value was getting merged into mode (where it wasPeter Seebach
ignored) rather than flags (where it was needed), meaning that the open64 type functions didn't work as intended on 32-bit hosts.
2012-02-06fix spaces/tabs in python againPeter Seebach
2012-02-06Fix *at() function interface holesPeter Seebach
1. Fix *at() where dirfd is obtained through dirfd(DIR *). The dirfd(DIR *) interface allows you to get the fd for a DIR *, meaning you can use it with openat(), meaning you can need its path. This causes a segfault. Also fixed the base_path code not to segfault in that case, but first fix the underlying problem. 2. Implement renameat() After three long years, someone tried to use this. This was impossibly hard back when pseudo was written, because there was only one dirfd provided for. Thing is, now, the canonicalization happens in wrapfuncs, so a small tweak to makewrappers to recognize that oldpath should use olddirfd if it exists is enough to get us fully canonicalized paths when needed.

2011-11-02Rework the clone wrapper to add an intermediate function to resolve a defect.Mark Hatle
Previously the clone(2) wrapper unconditionallity restored the system environment. It also invokes the checks to see if the user has requested pseudo to be disabled or unloaded. Due to the semantics of clone, this caused both the parent and child processes to be disabled or unloaded. The new code adds an intermediate function, wrap_clone_child, that only runs within the child context. This way we can be sure to only disable/unload pseudo from within the child process. In addition, we avoid mucking with the environment if CLONE_VM is set, since this will affect both parent and child. Signed-off-by: Mark Hatle <mark.hatle@windriver.com>
2011-11-02Implement PSEUDO_UNLOAD, replacing existing PSEUDO_RELOADED semantics.Mark Hatle
Change from internal PSEUDO_RELOADED to external PSEUDO_UNLOAD environment variable. Enable external programs to have a safe and reliable way to unload pseudo on the next exec*. PSEUDO_UNLOAD also will disable pseudo if we're in a fork/clone situation in the same way PSEUDO_DISABLED=1 would. Rename the PSEUDO_DISABLED tests, and create a similar set for the new PSEUDO_UNLOAD. Signed-off-by: Mark Hatle <mark.hatle@windriver.com>
2011-07-19Fix uninitalized variable.Peter Seebach
You might be wondering why this wasn't caught. Answer: gcc's too smart. Consider: int x; if (condition) x = 23; return x; This function will just return 23. Since gcc knows that it doesn't matter what happens if x is used uninitialized (it's an indeterminate value, thus a possible trap representation, thus undefined behavior to use it), it simplifies the initial part of this away. Thus there's no use of an uninitialized value. Something similar seems to be at issue with the use of the uninitialized f in pseudo_init_one_wrapper. The variable wasn't initialized in the pre-realpath-fix version either, but in that version, the assignment from dlsym was completely unconditional.
2011-06-09Fix realpath(name, NULL) when PSEUDO_DISABLED=1Peter Seebach
On some Linux systems, dlsym("realpath", RTLD_NEXT) prefers for reasons of its own to give a symbol that is also known as old_realpath, which fails and yields EINVAL when called with a null pointer as the second argument. This can be avoided, on some systems, by using dlvsym() to request the GLIBC_2.3 version of the symbol. The wrapper logic is enhanced to allow for specifying versions, although this currently only works for Linux (Darwin has no dlvsym, apparently?). The test case is a trivial program which calls realpath(name, NULL) run with PSEUDO_DISABLED=1.

2011-06-02Call this "version 1.1".Peter Seebach
2011-06-02Add system() wrapper to force setup of the pseudo environment. NotePeter Seebach
that we add an extra fork() so we can do the setup in a child process, but still just pass the command string to the standard system() call.
2011-05-31Change logic on file creation/chmod so that we only secretly mask inPeter Seebach
the 0100 bit for directories. The reason is that otherwise we create plain files which are 0700 on disk, which means they're non-zero &0111, which breaks euidaccess(X_OK).

2011-05-02Merge pull request #1 from cgwalters/master.Peter Seebach
Build improvements (better compatibility with how other people do things)
2011-05-02configure: Ignore unknown argumentsColin Walters
This is what GNU configure does, for valid reasons. My build wrapper unconditionally passes --enable-maintainer-mode.
2011-05-02Accept --libdirColin Walters
The way multilib works on at least Fedora is that --libdir=$prefix/lib64 is passed to configure. The source build system should not attempt to guess at architecture or take other configure flags (like --bits); instead it should default to whatever the given $(CC) does. This patch preserves the ability to specify --bits however.

debugger messages from going to the wrong place. No longer fclose(stderr) after grabbing log file, because stderr is likely still using fd 2.
2011-03-25Make subports/preports executable.Peter Seebach
2011-03-25Merge in ports workPeter Seebach
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.
2011-03-25Fix execvp crashPeter Seebach
2011-02-10Whoops! If LOCALSTATEDIR doesn't exist, and you invoke pseudoPeter Seebach
directly rather than via an on-demand spawn from the client, the directory is never created.

2011-02-08Expand paths on exec.Peter Seebach
This is fussy, because we have to actually do the path search ourselves as best we can to handle unqualified paths. The result, though, is more meaningful logs. Along the way, fix some bitrot in the comments in pseudo_fix_path and friends.

This reverts commit 49d4d35918d457b0e9206679ecad3b9c84f11e66.
2011-01-18Do not cache OP_EXEC callsMark Hatle
The cached data values were being collected when an OP_EXEC call was made. This is incorrect as the values are only for logging purposes. It's believed this caused an occasional crash in certain instances. Signed-off-by: Mark Hatle <mark.hatle@windriver.com>
2011-01-14Automatically create state/prefix directoriesPeter Seebach
It'd be handy for the WR build system if new state directories could be created as needed. It is made so. And to answer the first question everyone, including me, has on reading this: You can't do system("mkdir -p ...") because the invoked shell would need to run under pseudo, so it'd have to check for a server, and...

2011-01-13Fixup: The path code could double-free.Peter Seebach
The problem is that path_by_ino could end up being the same pointer as cache_path, after which, if cache_path were freed (or kept around for later), there would be malloc arena problems. Also, fix the calculation for pathlen to increase cache hits. The IPC messages use length of path *plus one* as the length, because the buffer is defined to include its terminating null byte.
2010-12-17Fix the msg cache codeMark Hatle
The pathlen that is cached could be wrong in certain operations (RENAME). Fix this by resetting it to the proper path length. Signed-off-by: Mark Hatle <mark.hatle@windriver.com>
2010-12-17When pseudo is disabled avoid directory processing...Mark Hatle
When pseudo is disabled, we skip a bunch of the prefix, localstate, etc processing. This allows pseudo to run with a directory that does not yet exist. Signed-off-by: Mark Hatle <mark.hatle@windriver.com>

2010-12-16Change the file journal from PERSIST to OFFMark Hatle
Changing the file journal to OFF, this makes things a bit more susceptible to failure in cases where pseudo crashes or the system crashes.. however, this is believed to be unlikely. Timing: Before: real 6m42.093s user 0m34.321s sys 2m46.086s (with journal set to MEMORY) real 6m33.037s user 0m33.133s sys 2m48.668s After (journal set to OFF) real 6m17.313s user 0m32.757s sys 2m47.654s Signed-off-by: Mark Hatle <mark.hatle@windriver.com>
2010-12-16Optimize the sql database indexes differently...Mark Hatle
We change the index from simply "path" to "path, dev, ino". This allows for slightly faster searches for the exact file information, and does not cause any penalty for a simple "path" based search. Signed-off-by: Mark Hatle <mark.hatle@windriver.com>
2010-12-16Add a cache of the last object found in pseudo_opMark Hatle
Add a cache of the last object found in pseudo_op. Profiling has indiciated that many operations come in clusters. So instead of doing select, operation for each item in the cluster, we check to see if we already know the item and perform the op.. Performance improvement when processing 500k or so files: Previous: real 7m11.778s user 0m35.929s sys 2m46.723s This commit: real 6m42.093s user 0m34.321s sys 2m46.086s Also validation of the component can be added by compiling with NVALIDATE. This verifies the result of the cache is the same as what would have come from the database. Differences are logged to the standard pseudo.log. Signed-off-by: Mark Hatle <mark.hatle@windriver.com>
