| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a pack.packSizeLimit is set, we may split the pack data across multiple packfiles. This means we cannot generate .bitmap files, as they require that all of the reachable objects are in the same pack. We check that condition when we are generating the list of objects to pack (and disable bitmaps if we are not packing everything), but we forgot to update it when we notice that we needed to split (which doesn't happen until the actual write phase). The resulting bitmaps are quite bogus (they mention entries that do not exist in the pack!) and can cause a fetch or push to send insufficient objects.

This makes "git am" work for people who erroneously paste the whole output from format-patch: From 12345abcd...fedcba543210 Mon Sep 17 00:00:00 2001 From: them Subject: [PATCH] whatever into their email body (assuming that an mbox writer then quotes "From" as ">From", as otherwise we would actually mailsplit on the in-body line). However, this has false positives if somebody actually has a commit body that starts with "From "; in this case we erroneously remove the line entirely from the commit message. We can make this check more robust by making sure the line actually looks like a real mbox "From" line. Inspect the line that begins with ">From " a more carefully to only skip lines that match the expected pattern (note that the datestamp part of the format-patch output is designed to be kept constant to help those who write magic(5) entries).

However, it will not exit non-zero for any missing ref tips, meaning that a severely broken repository may still pass "git fsck && echo ok". The problem is that we use for_each_ref to iterate over the ref tips, which hides broken tips. It does at least print an error from the refs.c code, but fsck does not ever see the ref and cannot note the problem in its exit code. We can solve this by using for_each_rawref and noting the error ourselves. In addition to adding tests for this case, we add tests for all types of missing-object links (all of which worked, but which we were not testing).

The problem lies with the regexp used for simulating --add in `git_config_set_multivar_in_file()`, "^$", which in ideal case should not match with any string but is true for empty strings. Instead use a regexp like "a^" which can not be true for any string, empty or not. For removing the segfault add a check for NULL values in `matches()` in config.c.

In this case, it is used to check whether we have an already-parsed object before calling parse_object, to save us from reading the object from disk. Using lookup_object would be fine for that purpose, but we can take it a step further. Since this code was written, parse_object already learned the "check lookup_object" optimization, so we can simply call parse_object directly.

Individual instances are allocated as concrete types (or as a union type that can store any object), and a "struct object *" can be cast into its real type after examining its "type" enum. This means it is dangerous to have a type field that does not match the allocation (e.g., setting the type field of a "struct blob" to "OBJ_COMMIT" would mean that a reader might read past the allocated memory). In most of the current code this is not a problem; the first thing we do after allocating an object is usually to set its type field by passing it to create_object. However, the virtual commits we create in merge-recursive.c do not ever get their type set. This does not seem to have caused problems in practice, though (presumably because we always pass around a "struct commit" pointer and never even look at the type). We can fix this oversight and also make it harder for future code to get it wrong by setting the type directly in the object allocation functions. This will also make it easier to fix problems with commit index allocation, as we know that any object allocated by alloc_commit_node will meet the invariant that an object with an OBJ_COMMIT type field will have a unique index number.

When we resolve a particular delta, we flip its "real_type" field from OBJ_{REF,OFS}_DELTA to whatever the real type is. We assume that traversing the objects this way will visit each delta only once. This is correct for most packs; we visit the delta only when we process its base, and each object (and thus each base) appears only once. However, if a base object appears multiple times in the pack, we will try to resolve any deltas based on it once for each instance. We can detect this case by noting that a delta we are about to resolve has already had its real_type field flipped, and we already do so with an assert(). However, if multiple threads are in use, we may race with another thread on comparing and flipping the field. We need to synchronize the access. The right mechanism for doing this is a compare-and-swap (we atomically "claim" the delta for our own and find out whether our claim was successful). We can implement this in C by using a pthread mutex to protect the operation. This is not the fastest way of doing a compare-and-swap; many processors provide instructions for this, and gcc and other compilers provide builtins to access them. However, some experiments showed that lock contention does not cause a significant slowdown here. Adding c-a-s support for many compilers would increase the maintenance burden (and we would still end up including the pthread version as a fallback). Note that we only need to touch the OBJ_REF_DELTA codepath here. An OBJ_OFS_DELTA object points to its base using an offset, and therefore has only one base, even if another copy of that base object appears in the pack (we do still touch it briefly because the setting of real_type is factored out of resolve_data).

However, it can sometimes fail when pushing over http, because we have to spawn "git send-pack --stateless-rpc" to do the heavy lifting, and we pass each refspec on the command line. This can cause us to overflow the OS limits on the size of the command line for a large push. We can solve this by giving send-pack a --stdin option and using it from remote-curl. We already dealt with this on the fetch-pack side in 078b895 (fetch-pack: new --stdin option to read refs from stdin, 2012-04-02). The stdin option (and in particular, its use of packet-lines for stateless-rpc input) is modeled after that solution.

Unlike a Git-generated patch, a non-Git patch is taken to have the pathnames relative to the current working directory. The names found in such a patch are modified by prepending the prefix by the prefix_patches() helper function introduced in 56185f49 (git-apply: require -p<n> when working in a subdirectory., 2007-02-19). However, this prefixing is done after the patch is fully parsed and affects only what target files are patched. Because the attributes are checked against the names found in the patch during the parsing, not against the final pathname, the whitespace check that is done during parsing ends up using attributes for a wrong path for non-Git patches. Fix this by doing the prefix much earlier, immediately after the header part of each patch is parsed and we learn the name of the path the patch affects.

Whereas a shallow repository (or a shallow operation in a repository) is inherently cutting off the object graph with a graft. We explicitly disallow the use of bitmaps in shallow repositories by checking is_repository_shallow(), and we should continue to do that. However, we also want to disallow bitmaps when we are serving a fetch to a shallow client, since we momentarily take on their grafted view of the world. It used to be enough to call is_repository_shallow at the start of pack-objects. Upload-pack wrote the other side's shallow state to a temporary file and pointed the whole pack-objects process at this state with "git --shallow-file", and from the perspective of pack-objects, we really were in a shallow repo. But since b790e0f (upload-pack: send shallow info over stdin to pack-objects, 2014-03-11), we do it differently: we send --shallow lines to pack-objects over stdin, and it registers them itself. This means that our is_repository_shallow check is way too early (we have not been told about the shallowness yet), and that it is insufficient (calling is_repository_shallow is not enough, as the shallow grafts we register do not change its return value).

If we don't have a space, then we set our pointer to the end-of-line. However, we don't double-check that our end-of-line pointer is valid (e.g., if we got a truncated diff input), which could lead to some wrap-around pointer arithmetic. In most cases this would probably get caught by our "40 < len" check later in the function, but to be on the safe side, let's just use strchrnul to treat end-of-string the same as end-of-line.

In this case, it is used to check whether we have an already-parsed object before calling parse_object, to save us from reading the object from disk. Using lookup_object would be fine for that purpose, but we can take it a step further. Since this code was written, parse_object already learned the "check lookup_object" optimization, so we can simply call parse_object directly.

Individual instances are allocated as concrete types (or as a union type that can store any object), and a "struct object *" can be cast into its real type after examining its "type" enum. This means it is dangerous to have a type field that does not match the allocation (e.g., setting the type field of a "struct blob" to "OBJ_COMMIT" would mean that a reader might read past the allocated memory). In most of the current code this is not a problem; the first thing we do after allocating an object is usually to set its type field by passing it to create_object. However, the virtual commits we create in merge-recursive.c do not ever get their type set. This does not seem to have caused problems in practice, though (presumably because we always pass around a "struct commit" pointer and never even look at the type). We can fix this oversight and also make it harder for future code to get it wrong by setting the type directly in the object allocation functions. This will also make it easier to fix problems with commit index allocation, as we know that any object allocated by alloc_commit_node will meet the invariant that an object with an OBJ_COMMIT type field will have a unique index number.
