What (small set of) steps will reproduce the problem?
"require" and "use" support a ":reload-all" flag that is intended to
cause the specified libs to be reloaded along with all libs on which
they directly or indirectly depend. This is implemented by temporarily
binding a "loaded-libs" var to the empty set and then loading the
AOT compilation added another "already loaded" mechanism to
clojure.lang.RT.load() which is currently not sensitive to a "reload-
all" being in progress and breaks its operation in the following case:
A, B, and C are libs
A depends on B. (via :require in its ns form)
B depends on C. (via :require in its ns form)
B has been compiled (B.class is on classpath)
At the repl I "require" A which loads A, B, and C (either from
class files or clj files)
I modify C.clj
At the repl I "require" A with the :reload-all flag, intending to
pick up the changes to C
C is not reloaded because RT.load() skips loading B: B.class
exists, is already loaded, and B.clj hasn't changed since it was compiled.
What is the expected output? What do you see instead?
I expect :reload-all to be effective. It isn't.
What version are you using?
svn 1354, 1.0.0RC1
Was this discussed on the group? If so, please provide a link to the
Please provide any additional information below.
I'll upload a patch soon that creates a "*reload-all*" var with a
root binding of nil and code to bind it to true when the current
thread has a :reload-all call pending. When *reload-all* is true,
RT.load() will (re)load all libs from their ".clj" files even if
they're already loaded.
The fix for this may need to be coordinated with a fix for issue #3.
