hashmap: use *_entry APIs for iteration
hashmap_cmp_fn takes hashmap_entry params
hashmap_get{,_from_hash} return "struct hashmap_entry *"
hashmap: use *_entry APIs to wrap container_of
hashmap_get_next returns "struct hashmap_entry *"
introduce container_of macro
hashmap_put takes "struct hashmap_entry *"
hashmap_remove takes "const struct hashmap_entry *"
hashmap_get takes "const struct hashmap_entry *"
hashmap_add takes "struct hashmap_entry *"
hashmap_get_next takes "const struct hashmap_entry *"
hashmap_entry_init takes "struct hashmap_entry *"
packfile: use hashmap_entry in delta_base_cache_entry
coccicheck: detect hashmap_entry.hash assignment
diff: use hashmap_entry_init on moved_entry.ent

Since these macros already take a `keyvar' pointer of a known type,
we can rely on OFFSETOF_VAR to get the correct offset without
relying on non-portable `__typeof__' and `offsetof'.
Argument order is also rearranged, so `keyvar' and `member' are
sequential as they are used as: `keyvar->member'

Add a new option, --mark-tags, which will output mark identifiers with
each tag object. This improves the incremental export story with
--export-marks since it will allow us to record that annotated tags have
been exported, and it is also needed as a step towards supporting nested
tags.

fast-import has support for both an --import-marks flag and an

file does not exist. fast-export only had support for an --import-marks
flag; add an --import-marks-if-exists flag for consistency.

fast-export allows specifying revision ranges, which can be used to
export a tag without exporting the commit it tags. fast-export handled
this rather poorly: it would emit a "from :0" directive. Since marks
start at 1 and increase, this means it refers to an unknown commit and
fast-import will choke on the input.
When we are unable to look up a mark for the object being tagged, use a
"from $HASH" directive instead to fix this problem.
Note that this is quite similar to the behavior fast-export exhibits
with commits and parents when --reference-excluded-parents is passed
along with an excluded commit range. For tags of excluded commits we do
not require the --reference-excluded-parents flag because we always have
to tag something. By contrast, when dealing with commits, pruning a
parent is always a viable option, so we need the flag to specify that
parent pruning is not wanted. (It is slightly weird that
--reference-excluded-parents isn't the default with a separate
--prune-excluded-parents flag, but backward compatibility concerns
resulted in the current defaults.)

There are no callers left of lookup_object() that aren't just passing us
the "hash" member of a "struct object_id". Let's take the whole struct,
which gets us closer to removing all raw sha1 variables. It also
matches the existing conversions of lookup_blob(), etc.
The conversions of callers were done by hand, but they're all mechanical
one-liners.

Automatic re-encoding of commit messages (and dropping of the encoding
header) hurts attempts to do reversible history rewrites (e.g. sha1sum
<-> sha256sum transitions, some subtree rewrites), and seems
inconsistent with the general principle followed elsewhere in
fast-export of requiring explicit user requests to modify the output
(e.g. --signed-tags=strip, --tag-of-filtered-object=rewrite). Add a
--reencode flag that the user can use to specify, and like other
fast-export flags, default it to 'abort'.

The find_encoding() function returned the encoding used by a commit
message, returning a default of git_commit_encoding (usually UTF-8).
Although the current code does not differentiate between a commit which
explicitly requested UTF-8 and one where we just assume UTF-8 because no
encoding is set, it will become important when we try to preserve the
encoding header. Since is_encoding_utf8() returns true when passed
NULL, we can just return NULL from find_encoding() instead of returning
git_commit_encoding.

When fast-export encounters a commit with an 'encoding' header, it tries
to reencode in UTF-8 and then drops the encoding header. However, if it
fails to reencode in UTF-8 because e.g. one of the characters in the
commit message was invalid in the old encoding, then we need to retain
the original encoding or otherwise we lose information needed to
understand all the other (valid) characters in the original commit
message.

Small fixes and features for fast-export and fast-import, mostly on
the fast-export side.
* en/fast-export-import:
fast-export: add a --show-original-ids option to show original names
fast-import: remove unmaintained duplicate documentation
fast-export: add --reference-excluded-parents option
fast-export: ensure we export requested refs
fast-export: when using paths, avoid corrupt stream with non-existent mark
fast-export: move commit rewriting logic into a function for reuse
fast-export: avoid dying when filtering by paths and old tags exist
fast-export: use value from correct enum
git-fast-export.txt: clarify misleading documentation about rev-list args
git-fast-import.txt: fix documentation for --quiet option
fast-export: convert sha1 to oid
|
|
Knowing the original names (hashes) of commits can sometimes enable
post-filtering that would otherwise be difficult or impossible. In
particular, the desire to rewrite commit messages which refer to other
prior commits (on top of whatever other filtering is being done) is
very difficult without knowing the original names of each commit.
In addition, knowing the original names (hashes) of blobs can allow
filtering by blob-id without requiring re-hashing the content of the
blob, and is thus useful as a small optimization.
Once we add original ids for both commits and blobs, we may as well
add them for tags too for completeness. Perhaps someone will have a
use for them.
This commit teaches a new --show-original-ids option to fast-export
which will make it add a 'original-oid <hash>' line to blob, commits,
and tags. It also teaches fast-import to parse (and ignore) such
lines.

git filter-branch has a nifty feature allowing you to rewrite, e.g. just
the last 8 commits of a linear history
git filter-branch $OPTIONS HEAD~8..HEAD
If you try the same with git fast-export, you instead get a history of
only 8 commits, with HEAD~7 being rewritten into a root commit. There
are two alternatives:
1) Don't use the negative revision specification, and when you're
filtering the output to make modifications to the last 8 commits,
just be careful to not modify any earlier commits somehow.
2) First run 'git fast-export --export-marks=somefile HEAD~8', then
run 'git fast-export --import-marks=somefile HEAD~8..HEAD'.
Both are more error prone than I'd like (the first for obvious reasons;
with the second option I have sometimes accidentally included too many
revisions in the first command and then found that the corresponding
extra revisions were not exported by the second command and thus were
not modified as I expected). Also, both are poor from a performance
perspective.
Add a new --reference-excluded-parents option which will cause
fast-export to refer to commits outside the specified rev-list-args
range by their sha1sum. Such a stream will only be useful in a
repository which already contains the necessary commits (much like the
restriction imposed when using --no-data).
Note from Peff:
I think we might be able to do a little more optimization here. If
we're exporting HEAD^..HEAD and there's an object in HEAD^ which is
unchanged in HEAD, I think we'd still print it (because it would not
be marked SHOWN), but we could omit it (by walking the tree of the
boundary commits and marking them shown). I don't think it's a
blocker for what you're doing here, but just a possible future
optimization.

If file paths are specified to fast-export and a ref points to a commit
that does not touch any of the relevant paths, then that ref would
sometimes fail to be exported. (This depends on whether any ancestors
of the commit which do touch the relevant paths would be exported with
that same ref name or a different ref name.) To avoid this problem,
put *all* specified refs into extra_refs to start, and then as we export
each commit, remove the refname used in the 'commit $REFNAME' directive
from extra_refs. Then, in handle_tags_and_duplicates() we know which
refs actually do need a manual reset directive in order to be included.
This means that we do need some special handling for excluded refs; e.g.
if someone runs
git fast-export ^master master
then they've asked for master to be exported, but they have also asked
for the commit which master points to and all of its history to be
excluded. That logically means ref deletion. Previously, such refs
were just silently omitted from being exported despite having been
explicitly requested for export.

If file paths are specified to fast-export and multiple refs point to a
commit that does not touch any of the relevant file paths, then
fast-export can hit problems. fast-export has a list of additional refs
that it needs to explicitly set after exporting all blobs and commits,
and when it tries to get_object_mark() on the relevant commit, it can
get a mark of 0, i.e. "not found", because the commit in question did
not touch the relevant paths and thus was not exported. Trying to
import a stream with a mark corresponding to an unexported object will
cause fast-import to crash.
Avoid this problem by taking the commit the ref points to and finding an
ancestor of it that was exported, and make the ref point to that commit
instead.

If --tag-of-filtered-object=rewrite is specified along with a set of
paths to limit what is exported, then any tags pointing to old commits
that do not contain any of those specified paths cause problems. Since
the old tagged commit is not exported, fast-export attempts to rewrite
such tags to an ancestor commit which was exported. If no such commit
exists, then fast-export currently die()s. Five years after the tag
rewriting logic was added to fast-export (see commit 2d8ad4691921,
"fast-export: Add a --tag-of-filtered-object option for newly dangling
tags", 2009-06-25), fast-import gained the ability to delete refs (see
commit 4ee1b225b99f, "fast-import: add support to delete refs",
2014-04-20), so now we do have a valid option to rewrite the tag to.
Delete these tags instead of dying.

When printing variables which contain a size, today "unsigned long"
is used at many places.
In order to be able to change the type from "unsigned long" into size_t
some day in the future, we need to have a way to print 64 bit variables
on a system that has "unsigned long" defined to be 32 bit, like Win64.
Upcast all those variables into uintmax_t before they are printed.
This is to prepare for a bigger change, when "unsigned long"
will be converted into size_t for variables which may be > 4Gib.

Using the more restrictive oideq() should, in the long run,
give the compiler more opportunities to optimize these
callsites. For now, this conversion should be a complete
noop with respect to the generated code.
The result is also perhaps a little more readable, as it
avoids the "zero is equal" idiom. Since it's so prevalent in
C, I think seasoned programmers tend not to even notice it
anymore, but it can sometimes make for awkward double
negations (e.g., we can drop a few !!oidcmp() instances
here).
This patch was generated almost entirely by the included
coccinelle patch. This mechanical conversion should be
completely safe, because we check explicitly for cases where
oidcmp() is compared to 0, which is what oideq() is doing
under the hood. Note that we don't have to catch "!oidcmp()"
separately; coccinelle's standard isomorphisms make sure the
two are treated equivalently.
I say "almost" because I did hand-edit the coccinelle output
to fix up a few style violations (it mostly keeps the
original formatting, but sometimes unwraps long lines).

- indentation
- some messages are turned to BUG(), or prefixed with "BUG:" and will

- some messages are improved to give more information
- some messages are broken down by sentence to be i18n friendly

refspec_item's.

In preparation for introducing an abstraction around a collection of
refspecs (much like how a 'struct pathspec' is a collection of 'struct
pathspec_item's) rename the existing 'struct refspec' to 'struct
refspec_item'.

This should make these functions easier to find and cache.h less
overwhelming to read.
In particular, this moves:
- read_object_file
- oid_object_info
- write_object_file
As a result, most of the codebase needs to #include object-store.h.
In this patch the #include is only added to files that would fail to
compile otherwise. It would be better to #include wherever
identifiers from the header are used. That can happen later
when we have better tooling for it.

Clang 6 reports the following warning, which is turned into an error in a
DEVELOPER build:
builtin/fast-export.c:162:28: error: performing pointer arithmetic on a null pointer has undefined behavior [-Werror,-Wnull-pointer-arithmetic]
return ((uint32_t *)NULL) + mark;
~~~~~~~~~~~~~~~~~~ ^
1 error generated.
The compiler is correct, and the error message speaks for itself. There
is no need for any undefined operation -- just cast mark to void * or
uint32_t after an intermediate cast to uintptr_t. That encodes the
integer value into a pointer and later decodes it as intended.
While at it remove an outdated comment -- intptr_t has been used since
ffe659f94d (parse-options: make some arguments optional, add callbacks),
committed in October 2007.

"git fast-export" had a regression in v2.15.0 era where it skipped
some merge commits in certain cases, which has been corrected.
