drochner 1a9a16338e Remove some code which makes file lookup rely on the fact that
the first two directory entries are "." and "..".
This behaviour is not required by applicable standards, and
actually not provided by "coda".
Now we get the "." and ".." into the per-directiry hash tables,
but this should not hurt.

sjg 78610dd53d Whenever we update .PATH, set the variable ${.PATH} to reflect the
search list that will be used.  Thus 'dot' and 'cur' will appear in
${.PATH} either at the start or end depending on .DOTLAST even though
they are not strictly in dirSearchPath.

When .CURDIR is assigned to - re-set the 'cur' Path.

Finally, when checking subdirs, look in 'dot' and 'cur' (first or last
depending on .DOTLAST) just as we do in other situations.

pk f1ca4b0556 Resurrect revision 1.23: no need to stat .PHONY targets. 2002-02-03 20:08:30 +00:00
pk ce3fe4630a Fix the bug addressed in revision 1.27 properly. Analysis of the problem
(see also PR#15179):

  When looking up names which directory components (i.e. having slashes,
  except when of the form `./name'), FindFile()/DirLookup() first looks
  the final filename component in the cache for each directory on the search
  path and then proceeds to match the prefixed directory components by
  comparing them to the trailing directory components of the the search
  path being probed.

  This is not correct. When looking for `bar/target' in a path `.../src/foo',
  you want it to come up with `.../src/foo/bar/target' (if it exists). There's
  no point in comparing the the `bar' prefix on the target to the `foo' suffix
  on the search path. Indeed, this will cause a false match if those prefix
  and suffix components are actually equal and search path itself also has a
  file called `target'. For example, looking for `foo/target' in `.../src/foo'
  will spuriously match `.../src/foo/target', not `.../src/foo/foo/target'.

  This last bug prompted the change in dir.c, rev 1.27, which happens
  to partially workaround it by avoiding the above matching code in the
  case of the `curdir' search path entry (at the cost of incurring an
  exorbitant amount of cache misses). The situation is unchanged however,
  when processing other entries on the search path (e.g. those other than
  `dot' and `cur').

Drop the prefix matching code in DirLookup() entirely and use DirFindDot()
and DirLookup() only for names without proper directory components (i.e.
`target' and `./target). Otherwise, non-absolute names are dealt with by
DirLookupSubdir(), while absolute names can be checked for an exact match
of the directory components prefix against the directories on the current
search path. This allows for the use of the file cache to check the
existence of the file and additionally, provides a shortcut out of
Dir_FindFile() if we have the prefix match but not a cache entry (this
is especially beneficial for searches in .CURDIR when it's not equal
to `dot').

reinoud a233fbd53e Fix major bug in make(1) ... due to shadowing of the dotLast path used for
the .DOTLAST primitive by a boolean variable with the same name, this whole
mechanism was broken ... it doesn't save much stat calls but it was wrong.

Thanks to Jason Thorpe for the other shadow-variable fixing patches he
made.

tv e4b456f8b8 Redo the hashtable for "." if .OBJDIR changes. 2001-11-12 21:58:17 +00:00
tv 2814f4901b Fix long-standing bug where, if an objdir exists, searching the .PATH for a
file will strip any leading path on the filename when searching ${.CURDIR}.

This bug manifested itself more prominently with xsrc/xfree/xc/lib/GL/GL,
since we now always search ${.CURDIR} as an alternative to ${.OBJDIR}
(PR bin/14499).

thorpej 484fe86089 Correct an inverse initialization of a variable, which caused all .PATHs
to be treated as .DOTLAST.
1999-07-12 17:29:32 +00:00
thorpej 5a0addc0ef Add a mechanism for specifying that ${.CURDIR} will be searched last
in the presence of .PATH directives by specifying:

.PATH: .DOTLAST

This will be used to fixup the build system to work with both crypto-us
and crypto-intl sub-trees.

Instead of adding it in .PATH, handle it specially the same way as "." is
handled.

mycroft bcc725c5e3 Don't do a VPATH or .PATH search for .PHONY targets. (From Christos.) 1997-05-06 20:59:42 +00:00
christos 6cfa2388a9 Make used to add every directory where it found files in the search path.
I.e. if you had a line in your Makefile:
	../foo.o: foo.c
`..' would be added in the search path. The addition of such paths has
been now disabled. If a pathname contains a slash, then the directory
where such a file is found is not added to the search path. Of course
this eliminates most (all?) use of this function.
