Jeff King 6e454b9a31 clear parsed flag when we free tree buffers
Many code paths will free a tree object's buffer and set it
to NULL after finishing with it in order to keep memory
usage down during a traversal. However, out of 8 sites that
do this, only one actually unsets the "parsed" flag back.
Those sites that don't are setting a trap for later users of
the tree object; even after calling parse_tree, the buffer
will remain NULL, causing potential segfaults.

It is not known whether this is triggerable in the current
code. Most commands do not do an in-memory traversal
followed by actually using the objects again. However, it
does not hurt to be safe for future callers.

In most cases, we can abstract this out to a
"free_tree_buffer" helper. However, there are two
exceptions:

  1. The fsck code relies on the parsed flag to know that we
     were able to parse the object at one point. We can
     switch this to using a flag in the "flags" field.

  2. The index-pack code sets the buffer to NULL but does
     not free it (it is freed by a caller). We should still
     unset the parsed flag here, but we cannot use our
     helper, as we do not want to free the buffer.

Michael Haggerty 8d9c50105f Change check_ref_format() to take a flags argument
Change check_ref_format() to take a flags argument that indicates what
is acceptable in the reference name (analogous to "git
check-ref-format"'s "--allow-onelevel" and "--refspec-pattern").  This
is more convenient for callers and also fixes a failure in the test
suite (and likely elsewhere in the code) by enabling "onelevel" and
"refspec-pattern" to be allowed independently of each other.

Also rename check_ref_format() to check_refname_format() to make it
obvious that it deals with refnames rather than references themselves.

Thiago Farina 47e44ed1dc commit: Add commit_list prefix in two function names.
Add commit_list prefix to insert_by_date function and to sort_by_date,
so it's clear that these functions refer to commit_list structure.

René Scharfe 59c69c0c65 make alloc_ref_from_str() the new alloc_ref()
With all calls to alloc_ref() gone, we can remove it and then we're free
to give alloc_ref_from_str() the shorter name.  It's a much nicer
interface, as the callers always need to have a name string when they
allocate a ref anyway and don't need to calculate and pass its length+1
any more.

Brandon Casey f285a2d7ed Replace calls to strbuf_init(&foo, 0) with STRBUF_INIT initializer
Many call sites use strbuf_init(&foo, 0) to initialize local
strbuf variable "foo" which has not been accessed since its
declaration. These can be replaced with a static initialization
using the STRBUF_INIT macro which is just as readable, saves a
function call, and takes up fewer lines.

Jeff King 541fc218e6 Fix "git clone http://$URL" to check out the worktree when asked
The builtin-clone now does the http commit walking and the tree unpacking
in the same process, and the commit walker leaves the in-core objects in a
funny state.  When forgetting the data read from the tree object, the
object should be marked "not parsed yet" for later users.

Daniel Barkalow c13b2633f4 Make walker.fetch_ref() take a struct ref.
This simplifies a few things, makes a few things slightly more
complicated, but, more importantly, allows that, when struct ref can
represent a symref, http_fetch_ref() can return one.

Incidentally makes the string that http_fetch_ref() gets include "refs/"
(if appropriate), because that's how the name field of struct ref works.
As far as I can tell, the usage in walker:interpret_target() wouldn't have
worked previously, if it ever would have been used, which it wouldn't
(since the fetch process uses the hash instead of the name of the ref
there).

Shawn O. Pearce 2e13e5d892 Merge branch 'master' into db/fetch-pack
There's a number of tricky conflicts between master and
this topic right now due to the rewrite of builtin-push.
Junio must have handled these via rerere; I'd rather not
deal with them again so I'm pre-merging master into the
topic.  Besides this topic somehow started to depend on
the strbuf series that was in next, but is now in master.
It no longer compiles on its own without the strbuf API.

* master: (184 commits)
  Whip post 1.5.3.4 maintenance series into shape.
  Minor usage update in setgitperms.perl
  manual: use 'URL' instead of 'url'.
  manual: add some markup.
  manual: Fix example finding commits referencing given content.
  Fix wording in push definition.
  Fix some typos, punctuation, missing words, minor markup.
  manual: Fix or remove em dashes.
  Add a --dry-run option to git-push.
  Add a --dry-run option to git-send-pack.
  Fix in-place editing functions in convert.c
  instaweb: support for Ruby's WEBrick server
  instaweb: allow for use of auto-generated scripts
  Add 'git-p4 commit' as an alias for 'git-p4 submit'
  hg-to-git speedup through selectable repack intervals
  git-svn: respect Subversion's [auth] section configuration values
  gtksourceview2 support for gitview
  fix contrib/hooks/post-receive-email hooks.recipients error message
  Support cvs via git-shell
  rebase -i: use diff plumbing instead of porcelain
  ...

Daniel Barkalow 30ae764b1e Modularize commit-walker
This turns the extern functions to be provided by the backend into a
struct of pointers, renames the functions to be more
namespace-friendly, and updates http-fetch to this interface. It
removes the unused include from http-push.c. It makes git-http-fetch a
builtin (with the implementation a separate file, accessible
directly).
