|
||
* @brief A path manipulation library
|
||
*
|
||
* All incoming and outgoing paths are non-NULL and in UTF-8, unless
|
||
* otherwise documented.
|
||
*
|
||
* No result path ever ends with a separator, no matter whether the
|
||
* path is a file or directory, because we always canonicalize() it.
|
||
*
|
||
* Nearly all the @c svn_path_xxx functions expect paths passed into
|
||
* them to be in canonical form as defined by the Subversion path
|
||
* library itself. The only functions which do *not* have such
|
||
* expectations are:
|
||
*
|
||
* - @c svn_path_canonicalize()
|
||
* - @c svn_path_is_canonical()
|
||
* - @c svn_path_internal_style()
|
||
* - @c svn_path_uri_encode()
|
||
*
|
||
* For the most part, we mean what most anyone would mean when talking
|
||
* about canonical paths, but to be on the safe side, you must run
|
||
* your paths through @c svn_path_canonicalize() before passing them to
|
||
* other functions in this API.

|
||
*
|
||
* Here's the short version:
|
||
*
|
||
* 1. Disclaimer: if you wish to debate the following, talk to Karl. :-)
|
||
* Order matters for updates because a multi-arg update is not
|
||
* atomic, and CVS users are used to, when doing 'cvs up targetA
|
||
* targetB' seeing targetA get updated, then targetB. I think the
|
||
* idea is that if you're in a time-sensitive or flaky-network
|
||
* situation, a user can say, "I really *need* to update
|
||
* wc/A/D/G/tau, but I might as well update my whole working copy if
|
||
* I can." So that user will do 'svn up wc/A/D/G/tau wc', and if
|
||
* something dies in the middles of the 'wc' update, at least the
|
||
* user has 'tau' up-to-date.
|
||
*
|
||
* 2. Also, we have this notion of an anchor and a target for updates
|
||
* (the anchor is where the update editor is rooted, the target is
|
||
* the actual thing we want to update). I needed a function that
|
||
* would NOT screw with my input paths so that I could tell the
|
||
* difference between someone being in A/D and saying 'svn up G' and
|
||
* being in A/D/G and saying 'svn up .' -- believe it or not, these
|
||
* two things don't mean the same thing. svn_path_condense_targets()
|
||
* plays with absolute paths (which is fine, so does
|
||
* svn_path_remove_redundancies()), but the difference is that it
|
||
* actually tweaks those targets to be relative to the "grandfather
|
||
* path" common to all the targets. Updates don't require a
|
||
* "grandfather path" at all, and even if it did, the whole
|
||
* conversion to an absolute path drops the crucial difference
|
||
* between saying "i'm in foo, update bar" and "i'm in foo/bar,
|
||
* update '.'"
