2017-04-17replace: plug a memory leakLibravatar Junio C Hamano1-0/+1

2017-03-30avoid using fixed PATH_MAX buffers for refsLibravatar Jeff King1-23/+27
Many functions which handle refs use a PATH_MAX-sized buffer to do so. This is mostly reasonable as we have to write loose refs into the filesystem, and at least on Linux the 4K PATH_MAX is big enough that nobody would care. But: 1. The static PATH_MAX is not always the filesystem limit. 2. On other platforms, PATH_MAX may be much smaller. 3. As we move to alternate ref storage, we won't be bound by filesystem limits. Let's convert these to heap buffers so we don't have to worry about truncation or size limits. We may want to eventually constrain ref lengths for sanity and to prevent malicious names, but we should do so consistently across all platforms, and in a central place (like the ref code).

2017-02-20delete_ref: accept a reflog message argumentLibravatar Kyle Meyer1-1/+1
When the current branch is renamed with 'git branch -m/-M' or deleted with 'git update-ref -m<msg> -d', the event is recorded in HEAD's log with an empty message. In preparation for adding a more meaningful message to HEAD's log in these cases, update delete_ref() to take a message argument and pass it along to ref_transaction_delete(). Modify all callers to pass NULL for the new message argument; no change in behavior is intended. Note that this is relevant for HEAD's log but not for the deleted ref's log, which is currently deleted along with the ref. Even if it were not, an entry for the deletion wouldn't be present in the deleted ref's log. files_transaction_commit() writes to the log if REF_NEEDS_COMMIT or REF_LOG_ONLY are set, but lock_ref_for_update() doesn't set REF_NEEDS_COMMIT for the deleted ref because REF_DELETING is set. In contrast, the update for HEAD has REF_LOG_ONLY set by split_head_update(), resulting in the deletion being logged.

2015-06-12Allow to control where the replace refs are looked forLibravatar Mike Hommey1-3/+3
It can be useful to have grafts or replace refs for specific use-cases while keeping the default "view" of the repository pristine (or with a different set of grafts/replace refs). It is possible to use a different graft file with GIT_GRAFT_FILE, but while replace refs are more powerful, they don't have an equivalent override.

2015-05-25each_ref_fn: change to take an object_id parameterLibravatar Michael Haggerty1-1/+3
Change typedef each_ref_fn to take a "const struct object_id *oid" parameter instead of "const unsigned char *sha1". To aid this transition, implement an adapter that can be used to wrap old-style functions matching the old typedef, which is now called "each_ref_sha1_fn"), and make such functions callable via the new interface. This requires the old function and its cb_data to be wrapped in a "struct each_ref_fn_sha1_adapter", and that object to be used as the cb_data for an adapter function, each_ref_fn_adapter(). This is an enormous diff, but most of it consists of simple, mechanical changes to the sites that call any of the "for_each_ref" family of functions. Subsequent to this change, the call sites can be rewritten one by one to use the new interface.

2014-07-21replace: check mergetags when using --graftLibravatar Christian Couder1-0/+47
When using --graft, with a mergetag in the original commit, we should check that the commit pointed to by the mergetag is still a parent of then new commit we create, otherwise the mergetag could be misleading. If the commit pointed to by the mergetag is no more a parent of the new commit, we could remove the mergetag, but in this case there is a good chance that the title or other elements of the commit might also be misleading. So let's just error out and suggest to use --edit instead on the commit. Signed-off-by: Christian Couder <chriscool@tuxfamily.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2014-06-25replace: add a --raw mode for --editLibravatar Jeff King1-10/+21
One of the purposes of "git replace --edit" is to help a user repair objects which are malformed or corrupted. Usually we pretty-print trees with "ls-tree", which is much easier to work with than the raw binary data. However, some forms of corruption break the tree-walker, in which case our pretty-printing fails, rendering "--edit" useless for the user. This patch introduces a "--raw" option, which lets you edit the binary data in these instances. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2014-06-25avoid double close of descriptors handed to run_commandLibravatar Jeff King1-2/+0
When a file descriptor is given to run_command via the "in", "out", or "err" parameters, run_command takes ownership. The descriptor will be closed in the parent process whether the process is spawned successfully or not, and closing it again is wrong. In practice this has not caused problems, because we usually close() right after start_command returns, meaning no other code has opened a descriptor in the meantime. So we just get EBADF and ignore it (rather than accidentally closing somebody else's descriptor!). Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2014-04-29replace: refactor command-mode determinationLibravatar Jeff King1-8/+6
The git-replace command has three modes: listing, deleting, and replacing. The first two are selected explicitly. If none is selected, we fallback to listing when there are no arguments, and replacing otherwise. Let's figure out up front which operation we are going to do, before getting into the application logic. That lets us simplify our option checks (e.g., we currently have to check whether a useless "--force" is given both along with an explicit list, as well as with an implicit one). This saves some lines, makes the logic easier to follow, and will facilitate further cleanups.

2013-12-12builtin/replace: unset read_replace_refsLibravatar Christian Couder1-0/+2
When checking to see if some objects are of the same type and when displaying the type of objects, git replace uses the sha1_object_info() function. Unfortunately this function by default respects replace refs, so instead of the type of a replaced object, it gives the type of the replacement object which might be different. To fix this bug, and because git replace should work at a level before replacement takes place, let's unset the read_replace_refs global variable at the beginning of cmd_replace().

2013-12-12builtin/replace: teach listing using short, medium or full formatsLibravatar Christian Couder1-7/+54
By default when listing replace refs, only the sha1 of the replaced objects are shown. In many cases, it is much nicer to be able to list all the sha1 of the replaced objects along with the sha1 of the replacment objects. And in other cases it might be interesting to also show the types of the replaced and replacement objects. This patch introduce a new --format=<fmt> option where <fmt> can be any of the following: 'short': this is the same as when no --format option is used, that is only the sha1 of the replaced objects are shown 'medium': this also lists the sha1 of the replacement objects 'full': this shows the sha1 and the type of both the replaced and the replacement objects Some documentation and some tests will follow.

Users replacing an object with one of a different type were not prevented to do so, even if it was obvious, and stated in the doc, that bad things would result from doing that. To avoid mistakes, it is better to just forbid that though. If -f option, which means '--force', is used, we can allow an object to be replaced with one of a different type, as the user should know what (s)he is doing. If one object is replaced with one of a different type, the only way to keep the history valid is to also replace all the other objects that point to the replaced object. That's because: * Annotated tags contain the type of the tagged object. * The tree/parent lines in commits must be a tree and commits, resp. * The object types referred to by trees are specified in the 'mode' field: 100644 and 100755 blob 160000 commit 040000 tree (these are the only valid modes) * Blobs don't point at anything.

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.
