Add a repository argument to allow callers of is_repository_shallow to be more specific about which repository to handle.

2018-05-16object-store: move object access functions to object-store.hLibravatar Stefan Beller1-0/+1
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.

2018-05-06{fetch,upload}-pack: support filter in protocol v2Libravatar Jonathan Tan1-1/+14
The fetch-pack/upload-pack protocol v2 was developed independently of the filter parameter (used in partial fetches), thus it did not include support for it. Add support for the filter parameter. Like in the legacy protocol, the server advertises and supports "filter" only if uploadpack.allowfilter is configured. Like in the legacy protocol, the client continues with a warning if "--filter" is specified, but the server does not advertise it.

2018-03-29upload-pack: disable object filtering when disabled by configLibravatar Jonathan Nieder1-4/+4
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.

2017-09-24object_array: use `object_array_clear()`, not `free()`Libravatar Martin Ågren1-1/+1
Instead of freeing `foo.objects` for an object array `foo` (sometimes conditionally), call `object_array_clear(&foo)`. This means we don't poke as much into the implementation, which is already a good thing, but also that we release the individual entries as well, thereby fixing at least one memory-leak (in diff-lib.c). If someone is holding on to a pointer to an element's `name` or `path`, that is now a dangling pointer, i.e., we'd be turning an unpleasant situation into an outright bug. To the best of my understanding no such long-term pointers are being taken. The way we handle `study` in builting/reflog.c still looks like it might leak. That will be addressed in the next commit.

2017-04-27timestamp_t: a new data type for timestampsLibravatar Johannes Schindelin1-2/+2
Git's source code assumes that unsigned long is at least as precise as time_t. Which is incorrect, and causes a lot of problems, in particular where unsigned long is only 32-bit (notably on Windows, even in 64-bit versions). So let's just use a more appropriate data type instead. In preparation for this, we introduce the new `timestamp_t` data type. By necessity, this is a very, very large patch, as it has to replace all timestamps' data type in one go. As we will use a data type that is not necessarily identical to `time_t`, we need to be very careful to use `time_t` whenever we interact with the system functions, and `timestamp_t` everywhere else.

2017-04-23PRItime: introduce a new "printf format" for timestampsLibravatar Johannes Schindelin1-1/+1
Currently, Git's source code treats all timestamps as if they were unsigned longs. Therefore, it is okay to write "%lu" when printing them. There is a substantial problem with that, though: at least on Windows, time_t is *larger* than unsigned long, and hence we will want to switch away from the ill-specified `unsigned long` data type. So let's introduce the pseudo format "PRItime" (currently simply being defined to "lu") to make it easier to change the data type used for timestamps.

There are certain house-keeping tasks that need to be performed at the very beginning of any Git program, and programs that are not built-in commands had to do them exactly the same way as "git" potty does. It was easy to make mistakes in one-off standalone programs (like test helpers). A common "main()" function that calls cmd_main() of individual program has been introduced to make it harder to make mistakes. * jk/common-main: mingw: declare main()'s argv as const common-main: call git_setup_gettext() common-main: call restore_sigpipe_to_default() common-main: call sanitize_stdfds() common-main: call git_extract_argv0_path() add an extra level of indirection to main()

"upload-pack" allows a custom "git pack-objects" replacement when responding to "fetch/clone" via the uploadpack.packObjectsHook. * jk/upload-pack-hook: upload-pack: provide a hook for running pack-objects t1308: do not get fooled by symbolic links to the source tree config: add a notion of "scope" config: return configset value for current_config_ functions config: set up config_source for command-line config git_config_parse_parameter: refactor cleanup code git_config_with_options: drop "found" counting

This should be part of every program, as otherwise users do not get translated error messages. However, some external commands forgot to do so (e.g., git-credential-store). This fixes them, and eliminates the repeated code in programs that did remember to use it. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
