Edward Thomson 9d88300a 2022-02-05T12:35:46 fetch: support oids in fetch specs
Edward Thomson 07264ea7 2022-02-06T14:07:36 fetch: add a test for local fetching
Edward Thomson 7a00adcc 2022-02-06T14:58:33 remote: introduce git_remote_capabilities Provide a mechanism for (internal) users to determine a remote's capabilities from the transport.
Edward Thomson b5237767 2022-02-05T10:43:08 remote: refactor update tips function Move the functionality to update an individual tip out of the loop; although the update tip function remains rather gnarly, at least the outer function is a bit less onerous.
Edward Thomson b1e83cca 2022-02-05T09:26:54 remote: refactor ref updating Pull ref updating into its own function for future uses.
Edward Thomson fda59a76 2022-01-04T07:05:20 remote: honor `http.followRedirects` configuration option
Edward Thomson 515daeaf 2022-01-04T06:16:30 remote: introduce `follow_redirects` connect option Give callers the ability to select how to handle redirects - either supporting redirects during the initial connection (so that, for example, `git.example.com/repo` can redirect to `github.com/example/repo`) or all/no redirects. This is for compatibility with git.
Edward Thomson 6fc6eeb6 2021-12-24T15:14:38 remote: introduce `git_remote_connect_options` The existing mechanism for providing options to remote fetch/push calls, and subsequently to transports, is unsatisfactory. It requires an options structure to avoid breaking the API and callback signatures. 1. Introduce `git_remote_connect_options` to satisfy those needs. 2. Add a new remote connection API, `git_remote_connect_ext` that will take this new options structure. Existing `git_remote_connect` calls will proxy to that. `git_remote_fetch` and `git_remote_push` will proxy their fetch/push options to that as well. 3. Define the interaction between `git_remote_connect` and fetch/push. Connect _may_ be called before fetch/push, but _need not_ be. The semantics of which options would be used for these operations was not specified if you specify options for both connect _and_ fetch. Now these are defined that the fetch or push options will be used _if_ they were specified. Otherwise, the connect options will be used if they were specified. Otherwise, the library's defaults will be used. 4. Update the transports to understand `git_remote_connect_options`. This is a breaking change to the systems API.
Edward Thomson f99a0d69 2022-01-04T15:17:01 remote: improved error reporting Several places in the remote code identify an error and then swallow it; return the error.
Edward Thomson 33d0ad9c 2021-12-23T21:18:54 remote: refactor insteadof application Using the insteadof helper would leak memory when we didn't really want the pushInsteadOf configuration. Refactor the choice into the function that allocates memory (or now, not) and use a more idiomatic `int` return code.
Martin Kühl de665a43 2021-11-11T21:55:28 remote: improve apply_insteadof function signature

Edward Thomson f0e693b1 2021-09-07T17:53:49 str: introduce `git_str` for internal, `git_buf` is external libgit2 has two distinct requirements that were previously solved by `git_buf`. We require: 1. A general purpose string class that provides a number of utility APIs for manipulating data (eg, concatenating, truncating, etc). 2. A structure that we can use to return strings to callers that they can take ownership of. By using a single class (`git_buf`) for both of these purposes, we have confused the API to the point that refactorings are difficult and reasoning about correctness is also difficult. Move the utility class `git_buf` to be called `git_str`: this represents its general purpose, as an internal string buffer class. The name also is an homage to Junio Hamano ("gitstr"). The public API remains `git_buf`, and has a much smaller footprint. It is generally only used as an "out" param with strict requirements that follow the documentation. (Exceptions exist for some legacy APIs to avoid breaking callers unnecessarily.) Utility functions exist to convert a user-specified `git_buf` to a `git_str` so that we can call internal functions, then converting it back again.

Honor an empty configuration URL to override a proxy configuration. Add tests to ensure that configuration specificity is honored.

Edward Thomson 7442c000 2021-08-27T11:25:51 remote: deprecate resolve_url callback Using a callback to set a resolve_url is not particularly idiomatic. Deprecate it in favor of the `set_instance_url` and `set_instance_pushurl` functions which can now be called from the `git_remote_ready_cb` callback.
Edward Thomson 72df17c6 2021-08-27T10:59:51 remote: introduce git_remote_ready_cb Introduce a new callback that fires when the remote is ready to connect.
Edward Thomson 67240677 2021-05-14T00:33:08 remote: introduce set_instance_url Users may want to override the URL on a particular instance of a remote, instead of updating the configuration. Previously, users could use a callback to do this, but this is not particularly idiomatic.

Edward Thomson 32350e89 2021-01-07T14:01:30 remote: don't update invalid refs If a symbolic reference points to something invalid, then do not try to update it.
Edward Thomson d4196c06 2020-04-05T19:42:16 remote: use GIT_ASSERT
Edward Thomson cb4bfbc9 2020-04-05T11:07:54 buffer: git_buf_sanitize should return a value `git_buf_sanitize` is called with user-input, and wants to sanity-check that input. Allow it to return a value if the input was malformed in a way that we cannot cope.
Edward Thomson c7143d7c 2020-10-11T13:56:16 remote: deprecate git_remote_is_valid_name
Edward Thomson 55a7117d 2020-10-11T13:55:44 remote: use git_remote_name_is_valid
Edward Thomson 023ebb9a 2020-10-11T13:48:07 refs: introduce git_remote_name_is_valid Provide a function that can check remote name validity but can also signal when an error occurs. Use the name "name_is_valid", which is more suggestive of checking a given name, rather than "is_valid_name", which suggests that the function checks the validity of the current remote's name.
Edward Thomson 68e35588 2020-10-11T13:35:35 refspec: return GIT_EINVALIDSPEC for invalid specs Disambiguate invalid specifications in `git_refspec__parse` so that callers can determine the difference between invalid specifications and actual errors. No call sites wil propagagte this new error message to an end-user, so there is no user-facing API change.
Edward Thomson b52bb4d4 2020-10-11T13:20:52 refs: use git_reference_name_is_valid
Edward Thomson e3f065ea 2020-07-15T22:13:47 remote: update the default remote branch When the remote does not tell us its default, we have to guess what the default branch should be. Use our local initial branch configuration to inform the remote branch default when we clone.
Patrick Steinhardt c6184f0c 2020-06-08T21:07:36 tree-wide: do not compile deprecated functions with hard deprecation When compiling libgit2 with -DDEPRECATE_HARD, we add a preprocessor definition `GIT_DEPRECATE_HARD` which causes the "git2/deprecated.h" header to be empty. As a result, no function declarations are made available to callers, but the implementations are still available to link against. This has the problem that function declarations also aren't visible to the implementations, meaning that the symbol's visibility will not be set up correctly. As a result, the resulting library may not expose those deprecated symbols at all on some platforms and thus cause linking errors. Fix the issue by conditionally compiling deprecated functions, only. While it becomes impossible to link against such a library in case one uses deprecated functions, distributors of libgit2 aren't expected to pass -DDEPRECATE_HARD anyway. Instead, users of libgit2 should manually define GIT_DEPRECATE_HARD to hide deprecated functions. Using "real" hard deprecation still makes sense in the context of CI to test we don't use deprecated symbols ourselves and in case a dependant uses libgit2 in a vendored way and knows it won't ever use any of the deprecated symbols anyway.
Patrick Steinhardt a6c9e0b3 2020-06-08T12:40:47 tree-wide: mark local functions as static We've accumulated quite some functions which are never used outside of their respective code unit, but which are lacking the `static` keyword. Add it to reduce their linkage scope and allow the compiler to optimize better.
Edward Thomson 51eff5a5 2020-05-29T13:13:19 strarray: we should `dispose` instead of `free` We _dispose_ the contents of objects; we _free_ objects (and their contents). Update `git_strarray_free` to be `git_strarray_dispose`. `git_strarray_free` remains as a deprecated proxy function.
Patrick Steinhardt aa4cd778 2020-01-30T10:40:44 Merge pull request #5336 from libgit2/ethomson/credtype cred: change enum to git_credential_t and GIT_CREDENTIAL_*
Edward Thomson 3f54ba8b 2020-01-18T13:51:40 credential: change git_cred to git_credential We avoid abbreviations where possible; rename git_cred to git_credential. In addition, we have standardized on a trailing `_t` for enum types, instead of using "type" in the name. So `git_credtype_t` has become `git_credential_t` and its members have become `GIT_CREDENTIAL` instead of `GIT_CREDTYPE`. Finally, the source and header files have been renamed to `credential` instead of `cred`. Keep previous name and values as deprecated, and include the new header files from the previous ones.
Edward Thomson 82154e58 2020-01-18T17:41:21 remote functions: return an int Stop returning a void for functions, future-proofing them to allow them to fail.
Patrick Steinhardt e23c0b18 2019-08-02T07:52:58 remote: remove unused block of code In "remote.c", we have a chunk of code that is #ifdef'fed out via `#if 0` with a comment that we could export it as a helper function. The code was implemented in 2013 and ifdef'fed in 2014, which shows that there's clearly no interest in having such a helper at all. As this block has recently created some confusion about `p_getenv` due to it containing the only reference to that function in our codebase, let's remove this block altogether.
Edward Thomson 0b5ba0d7 2019-06-06T16:36:23 Rename opt init functions to `options_init` In libgit2 nomenclature, when we need to verb a direct object, we name a function `git_directobject_verb`. Thus, if we need to init an options structure named `git_foo_options`, then the name of the function that does that should be `git_foo_options_init`. The previous names of `git_foo_init_options` is close - it _sounds_ as if it's initializing the options of a `foo`, but in fact `git_foo_options` is its own noun that should be respected. Deprecate the old names; they'll now call directly to the new ones.
Erik Aigner 59647e1a 2019-04-08T15:54:25 remote: add callback to resolve URLs before connecting Since libssh2 doesn't read host configuration from the config file, this callback can be used to hand over URL resolving to the client without touching the SSH implementation itself.
Edward Thomson a1ef995d 2019-02-21T10:33:30 indexer: use git_indexer_progress throughout Update internal usage of `git_transfer_progress` to `git_indexer_progreses`.

Etienne Samson 10cba764 2018-07-06T21:58:34 remote: lower the default vector size to 8 As it is, this is space for 32 refs pointers, which feels a little much. Lower it to 8, as it is the minimum vector size anyway.
Etienne Samson d3650294 2018-06-20T02:27:14 remote: add a flag to prevent generation of the default fetchspec

Etienne Samson 3cbaebdf 2018-06-20T02:27:11 remote: provide a generic API for creating remotes This supersedes the functionality of remote_create_with_fetchspec, remote_create_anonymous and remote_create_detached.
Etienne Samson 43b4b2fa 2018-06-20T02:27:09 remote: merge if-statements We need a repo/config and a name to be able to do anything to the configuration. As such, those two tests can be merged so their conditions are shared.

Etienne Samson 1c176883 2018-09-07T10:36:15 remote: store the connection data in a private struct This makes it easier to pass connection-related options around (proxy & custom headers for now). This fixes a bug in git_push_finish, which didn't reuse the provided proxy if the connection closed between the call to `git_remote_push` and the finish step.

Patrick Steinhardt af3088e4 2018-06-29T11:45:15 refspec: rename `git_refspec__free` to `git_refspec__dispose` Since commit 630a67366 (refspec: add public parsing api, 2018-02-07), we now have two functions `git_refspec_free` and `git_refspec__free`. The difference is that the first one will free the structure itself, while the second one will only free the structure's contents. Use our new `dispose` naming pattern for the latter function to help avoid confusion.
Patrick Steinhardt ecf4f33a 2018-02-08T11:14:48 Convert usage of `git_buf_free` to new `git_buf_dispose`
Etienne Samson df4937b8 2018-04-18T20:57:16 remote: repo is optional here As per CID:1378747, we might be called with a NULL repo, which would be deferenced in write_add_refspec
Carlos Martín Nieto 1b4fbf2e 2017-11-19T09:47:07 remote: append to FETCH_HEAD rather than overwrite for each refspec We treat each refspec on its own, but the code currently overwrites the contents of FETCH_HEAD so we end up with the entries for the last refspec we processed. Instead, truncate it before performing the updates and append to it when updating the references.
Edward Thomson 1560b580 2017-08-15T10:35:47 Merge pull request #4288 from pks-t/pks/include-fixups Include fixups
Patrick Steinhardt 0c7f49dd 2017-06-30T13:39:01 Make sure to always include "common.h" first Next to including several files, our "common.h" header also declares various macros which are then used throughout the project. As such, we have to make sure to always include this file first in all implementation files. Otherwise, we might encounter problems or even silent behavioural differences due to macros or defines not being defined as they should be. So in fact, our header and implementation files should make sure to always include "common.h" first. This commit does so by establishing a common include pattern. Header files inside of "src" will now always include "common.h" as its first other file, separated by a newline from all the other includes to make it stand out as special. There are two cases for the implementation files. If they do have a matching header file, they will always include this one first, leading to "common.h" being transitively included as first file. If they do not have a matching header file, they instead include "common.h" as first file themselves. This fixes the outlined problems and will become our standard practice for header and source files inside of the "src/" from now on.
Eric Myhre 4bc16c37 2016-07-08T01:37:22 remote: add function to create detached remotes Right now it is only possible to create remotes from a repository. While this is probably the most common use-case, there are commands which make sense even without a repository, e.g. the equivalence of `git ls-remote`. Add a new function `git_remote_create_detached`, which simply accepts a URL.
Patrick Steinhardt 8897f8fe 2017-05-05T09:47:54 remote: reject various actions for detached remotes There are only few actions which actually make sense for a detached remote, like e.g. `git_remote_ls`, `git_remote_prune`. For all the other actions, we have to report an error when the remote has no repository attached to it. This commit does so and implements some tests.
Patrick Steinhardt fd2ff8c9 2017-05-05T09:21:58 remote: improve error message if no URL is set The current error message when connecting to a remote when no URL is set is missing information on whether it is missing a fetch or push URL. Furthermore, it results in undefined behavior when using a remote without name. Fix both issues.

Edward Thomson 909d5494 2016-12-29T12:25:15 giterr_set: consistent error messages Error messages should be sentence fragments, and therefore: 1. Should not begin with a capital letter, 2. Should not conclude with punctuation, and 3. Should not end a sentence and begin a new one
David Turner d81cb2e4 2016-07-15T13:32:23 remote: Handle missing config values when deleting a remote Somehow I ended up with the following in my ~/.gitconfig: [branch "master"] remote = origin merge = master rebase = true I assume something went crazy while I was running the git.git tests some time ago, and that I never noticed until now. This is not a good configuration, but it shouldn't cause problems. But it does. Specifically, if you have this in your config, and you perform the following set of actions: create a remote fetch from that remote create a branch off of the remote master branch called "master" delete the branch delete the remote The remote delete fails with the message "Could not find key 'branch.master.rebase' to delete". This is because it's iterating over the config entries (including the ones in the global config) and believes that there is a master branch which must therefore have these config keys. https://github.com/libgit2/libgit2/issues/3856

Patrick Steinhardt ec0c4c40 2015-05-04T11:59:20 remote: apply insteadOf configuration. A remote's URLs are now modified according to the url.*.insteadOf and url.*.pushInsteadOf configurations. This allows a user to replace URL prefixes by setting the corresponding keys. E.g. "url.foo.insteadOf = bar" would replace the prefix "bar" with the new prefix "foo".
Carlos Martín Nieto 9566ce43 2015-05-18T14:42:35 remote: call the update_tips callback for opportunisitc updates These are updates, same as the rest, we should call this callback. As we are using the callback, let's make sure to skip unnecessary updates.
Carlos Martín Nieto c6e942fb 2015-05-17T15:19:22 remote: validate refspecs before adding to config When we moved from acting on the instance to acting on the configuration, we dropped the validation of the passed refspec, which can lead to writing an invalid refspec to the configuration. Bring that validation back.
Carlos Martín Nieto ae5b9362 2015-05-17T15:11:45 remote: remove fetch parameter from create_anonymous An anonymous remote is not configured and cannot therefore have configured refspecs. Remove the parameter which adds this from the constructor.
Carlos Martín Nieto 70f7484d 2015-05-14T09:35:08 remote: get rid of the run-time refspec setters These were left over from the culling as it's not clear which use-cases might benefit from this. It is not clear that we want to support any use-case which depends on changing the remote's idea of the base refspecs rather than passing in different per-operation refspec list, so remove these functions.
