shallow: migrate shallow information into the object parser

We need to convert the shallow functions all at the same time
as we move the data structures they operate on into the repository.

path.c: migrate global git_path_* to take a repository argument

Migrate all git_path_* functions that are defined in path.c to take a
repository argument. Unlike other patches in this series, do not use the
#define trick, as we rewrite the whole function, which is rather small.

This doesn't migrate all the functions, as other builtins have their own
local path functions defined using GIT_PATH_FUNC. So keep that macro
around to serve the other locations.

cache: convert get_graft_file to handle arbitrary repositories

This conversion was done without the #define trick used in the earlier
series refactoring to have better repository access, because this function
is easy to review, as all lines are converted and it has only one caller.

object-store: move object access functions to object-store.h

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.

We have to convert all of the alloc functions at once, because alloc_report
uses a funky macro for reporting. It is better for the sake of mechanical
conversion to convert multiple functions at once rather than changing the

We record all memory allocation in alloc.c, and free them in
clear_alloc_state, which is called for all repositories except
the_repository.

repository: introduce parsed objects fieldStefan Beller Tue, 8 May 2018 19:37:24 +0000 (12:37 -0700)

repository: introduce parsed objects field

Convert the existing global cache for parsed objects (obj_hash) into
repository-specific parsed object caches. Existing code that uses
obj_hash are modified to use the parsed object cache of
the_repository; future patches will use the parsed object caches of
other repositories.

Another future use case for a pool of objects is ease of memory management
in revision walking: If we can free the rev-list related memory early in
pack-objects (e.g. part of repack operation) then it could lower memory
pressure significantly when running on large repos. While this has been
discussed on the mailing list lately, this series doesn't implement this.

cache.h: allow oid_object_info to handle arbitrary repositories

This involves also adapting oid_object_info_extended and a some
internal functions that are used to implement these. It all has to
happen in one patch, because of a single recursive chain of calls visits
all these functions.

oid_object_info_extended is also used in partial clones, which allow
fetching missing objects. As this series will not add the repository
struct to the transport code and fetch_object(), add a TODO note and
omit fetching if a user tries to use a partial clone in a repository
other than the_repository.

Among the functions modified to handle arbitrary repositories,
unpack_entry() is one of them. Note that it still references the globals
"delta_base_cache" and "delta_base_cached", but those are safe to be
referenced (the former is indexed partly by "struct packed_git *", which
is repo-specific, and the latter is only used to limit the size of the
former as an optimization).

replace-object: add repository argument to do_lookup_replace_object

Add a repository argument to allow the do_lookup_replace_object caller
to be more specific about which repository to handle. This is a small
mechanical change; it doesn't change the implementation to handle
repositories other than the_repository yet.

As with the previous commits, use a macro to catch callers passing a
repository other than the_repository at compile time.

replace-object: check_replace_refs is safe in multi... Stefan Beller Thu, 12 Apr 2018 00:21:08 +0000 (17:21 -0700)

replace-object: check_replace_refs is safe in multi repo environment

In e1111cef23 (inline lookup_replace_object() calls, 2011-05-15) a shortcut
for checking the object replacement was added by setting check_replace_refs
to 0 once the replacements were evaluated to not exist. This works fine in
with the assumption of only one repository in existence.

The assumption won't hold true any more when we work on multiple instances
of a repository structs (e.g. one struct per submodule), as the first
repository to be inspected may have no replacements and would set the
global variable. Other repositories would then completely omit their
evaluation of replacements.

This reverts back the meaning of the flag `check_replace_refs` of
"Do we need to check with the lookup table?" to "Do we need to read
the replacement definition?", adding the bypassing logic to
lookup_replace_object after the replacement definition was read.
As with the original patch, delay the renaming of the global variable

replace-object: eliminate replace objects prepared... Stefan Beller Thu, 12 Apr 2018 00:21:07 +0000 (17:21 -0700)

replace-object: eliminate replace objects prepared flag

Make the oidmap a pointer.

That way we eliminate the need for the global boolean
variable 'replace_object_prepared' as we can put this information
into the pointer being NULL or not.

Another advantage of this is that we would more quickly catch
code that tries to access replace-map without initializing it.

This also allows the '#include "oidmap.h"' introduced in a previous
patch to be replaced by the forward declaration of 'struct oidmap;'.
Keeping the type opaque discourages circumventing accessor functions;
not dragging in other headers avoids some compile time overhead.

One disadvantage of this is change is performance as we need to
pay the overhead for a malloc. The alternative of moving the
global variable into the object store is less modular code.

object-store: move lookup_replace_object to replace-object.h

lookup_replace_object is a low-level function that most users of the
object store do not need to use directly.

Move it to replace-object.h to avoid a dependency loop in an upcoming
change to its inline definition that will make use of repository.h.

replace-object: move replace_map to object store

The relationship between an object X and another object Y that
replaces the object X is defined only within the scope of a
single repository.

The exception in reachability rule around these replacement objects
is also local to a repository (i.e. if traversal from refs reaches
X, then both X and Y are reachable and need to be kept from gc).

changes made to 468165c1d8a442994a825f3684528361727cd8c0.

The topic appears to inflict severe regression in renaming merges,
even though the promise of it was that it would improve them.

We do not yet know which exact change in the topic was wrong, but in
the meantime, let's play it safe and revert it out of 'master'
before real Git-using projects are harmed.

cases, fetching into a repository with many loose objects from a
repository with small number of refs.

Rename detection logic in "diff" family that is used in "merge" has
learned to guess when all of x/a, x/b and x/c have moved to z/a,
z/b and z/c, it is likely that x/d added in the meantime would also
want to move to z/d by taking the hint that the entire directory
'x' moved to 'z'. A bug causing dirty files involved in a rename
to be overwritten during merge has also been fixed as part of this
work.

git-svn: allow empty email-address using authors-prog... Andreas Heiduk Sat, 24 Mar 2018 10:20:46 +0000 (11:20 +0100)

git-svn: allow empty email-address using authors-prog and authors-file

The email address in --authors-file and --authors-prog can be empty but
git-svn translated it into a fictional email address in the form

jondoe <jondoe@6aafaa21e0fb4338a68ab372a049893d>

containing the SVN repository UUID. Now git-svn behaves like git-commit:
If the email is *explicitly* set to the empty string using '<>', the
commit does not contain an email address, only the name:

jondoe <>

Allowing to remove the email address *intentionally* prevents automatic
systems from sending emails to those fictional addresses and avoids
cluttering the log output with unnecessary stuff.

git-svn: search --authors-prog in PATH too

In 36db1eddf9 ("git-svn: add --authors-prog option", 2009-05-14) the path
to authors-prog was made absolute because git-svn changes the current
directory in some situations. This makes sense if the program is part of
the repository but prevents searching via $PATH.

The old behaviour is still retained, but if the file does not exists, then
authors-prog is searched for in $PATH as any other command.

add -p: fix 2.17.0-rc* regression due to moved code

Fix a regression in 88f6ffc1c2 ("add -p: only bind search key if
there's more than one hunk", 2018-02-13) which is present in
2.17.0-rc*, but not 2.16.0.

In Perl, regex variables like $1 always refer to the last regex
match. When the aforementioned change added a new regex match between
the old match and the corresponding code that was expecting $1, the $1
variable would always be undef, since the newly inserted regex match
doesn't have any captures.

As a result the "/" feature to search for a string in a hunk by regex
completely broke, on git.git:

$ perl -pi -e 's/Git/Tig/g' README.md
$ ./git --exec-path=$PWD add -p
[..]
Stage this hunk [y,n,q,a,d,j,J,g,/,s,e,?]? s
Split into 4 hunks.
[...]
Stage this hunk [y,n,q,a,d,j,J,g,/,s,e,?]? /Many
Use of uninitialized value $1 in string eq at /home/avar/g/git/git-add--interactive line 1568, <STDIN> line 1.
search for regex? Many

I.e. the initial "/regex" command wouldn't work, and would always emit
a warning and ask again for a regex, now it works as intended again.

upload-pack: disable object filtering when disabled... Jonathan Nieder Wed, 28 Mar 2018 20:33:03 +0000 (13:33 -0700)

upload-pack: disable object filtering when disabled by config

When upload-pack gained partial clone support (v2.17.0-rc0~132^2~12,
2017-12-08), it was guarded by the uploadpack.allowFilter config item
to allow server operators to control when they start supporting it.

That config item didn't go far enough, though: it controls whether the
'filter' capability is advertised, but if a (custom) client ignores
the capability advertisement and passes a filter specification anyway,
the server would handle that despite allowFilter being false.

This is particularly significant if a security bug is discovered in
this new experimental partial clone code. Installations without
uploadpack.allowFilter ought not to be affected since they don't
intend to support partial clone, but they would be swept up into being
vulnerable.

Simplify and limit the attack surface by making uploadpack.allowFilter
disable the feature, not just the advertisement of it.

credential: ignore SIGPIPE when writing to credential... Erik E Brady Thu, 29 Mar 2018 18:00:56 +0000 (11:00 -0700)

credential: ignore SIGPIPE when writing to credential helpers

The credential subsystem can trigger SIGPIPE when writing to an
external helper if that helper closes its stdin before reading the
whole input. Normally this is rare, since helpers would need to read
that input to make a decision about how to respond, but:

1. It's reasonable to configure a helper which only handles "get"
while ignoring "store". Such a handler might not read stdin
for "store", thereby rapidly closing stdin upon helper exit.

2. A broken or misbehaving helper might exit immediately. That's an
error, but it's not reasonable for it to take down the parent Git
process with SIGPIPE.

Even with such a helper, seeing this problem should be rare. Getting
SIGPIPE requires the helper racily exiting before we've written the
fairly small credential output.
