|Status||resolved||Resolution||no change required|
|Target Version||4.00.2+dev||Fixed in Version|
|Summary||0004573: Packing modules without _tag|
|Description||Sorry for my bad english.|
Ocamlbuild try to find submodules for <ident>.mlpack file in same dir when the <ident>.mlpack file exists, but when we get "touch _tags" it's look at subdir <ident> for this modules.
|Tags||No tags attached.|

This is not a bug, but rather a not-well-documented feature of ocamlbuild, related to the default value of the "traverse" tag that controls recursive traversal of subdirectories.
Initially ocamlbuild has "traverse: true" in all circumstances, because that's the most convenient when compiling an OCaml project. However, that was a performance nightmare when ocamlbuild was called from somewhere else: calling ocamlbuild from your home directory could try to traverse it entirely!
So the change that was made (around 3.11 I'd guess) is to use a heuristic to detect whether we're in an real OCaml project, or in a random directory:
- if a "_tags" or a "myocamlbuild.ml" exists in the current working directory, then "traverse" is enabled by default (all subdirectories are recursively traversed)
- if no "_tags" and no "myocamlbuild.ml" file exists, "traverse" is not enabled by default
Note that in either case you can change this default by adding the "traverse" tag to specific subdirectories ("<foo>: traverse") or for everything ("true: traverse"), and conversely disabling it with "-traverse" instead -- either in a _tags file or through the -tag-line "..." option).
PS: I'm not fond of this heuristic, for precisely the reason that it is surprising that adding a "_tags" file would change the observed semantics. But I'm not sure what would be a better choice, and don't see how to change this without breaking compatibility.
