Carlos Martín Nieto 10940736 2015-06-01T22:15:11 clone: fall back to copying when linking does not work We use heuristics to make a decent guess at when we can save time and space by linking object files during a clone. Unfortunately checking the device id isn't enough, as those would be the same during e.g. a bind-mount, but the OS still does not allow us to link between mounts of the same filesystem. If we fail to perform the links, fall back to copying the contents into a new file as a last attempt.
Carlos Martín Nieto a4b6452a 2015-04-23T06:55:29 remote: remove git_remote_save() It has now become a no-op, so remove the function and all references to it.
Carlos Martín Nieto 77254990 2015-04-23T06:51:34 remote: remove live changing of refspecs The base refspecs changing can be a cause of confusion as to what is the current base refspec set and complicate saving the remote's configuration. Change `git_remote_add_{fetch,push}()` to update the configuration instead of an instance. This finally makes `git_remote_save()` a no-op, it will be removed in a later commit.
Carlos Martín Nieto 3eff2a57 2015-04-22T16:11:10 remote: move the update_fetchhead setting to the options While this will rarely be different from the default, having it in the remote adds yet another setting it has to keep around and can affect its behaviour. Move it to the options.
Carlos Martín Nieto 8f0104ec 2015-04-21T22:10:36 Remove the callbacks struct from the remote Having the setting be different from calling its actions was not a great idea and made for the sake of the wrong convenience. Instead of that, accept either fetch options, push options or the callbacks when dealing with the remote. The fetch options are currently only the callbacks, but more options will be moved from setters and getters on the remote to the options. This does mean passing the same struct along the different functions but the typical use-case will only call git_remote_fetch() or git_remote_push() and so won't notice much difference.
Carlos Martín Nieto 4e498646 2015-01-15T16:50:31 repository: remove log message override for switching the active branch We want to use the "checkout: moving from ..." message in order to let git know when a change of branch has happened. Make the convenience functions for this goal write this message.
Carlos Martín Nieto 6bfb990d 2015-01-07T14:47:02 branch: don't accept a reflog message override This namespace is about behaving like git's branch command, so let's do exactly that instead of taking a reflog message. This override is still available via the reference namespace.
Carlos Martín Nieto 659cf202 2015-01-07T12:23:05 Remove the signature from ref-modifying functions The signature for the reflog is not something which changes dynamically. Almost all uses will be NULL, since we want for the repository's default identity to be used, making it noise. In order to allow for changing the identity, we instead provide git_repository_set_ident() and git_repository_ident() which allow a user to override the choice of signature.
Carlos Martín Nieto 3f894205 2014-06-06T15:01:45 remote: allow overriding the refspecs for download and fetch With opportunistic ref updates, git has introduced the concept of having base refspecs *and* refspecs that are active for a particular fetch. Let's start by letting the user override the refspecs for download.
Carlos Martín Nieto 15c30b72 2014-09-02T13:23:54 clone: handle overly restrictive refspecs When the fetch refspec does not include the remote's default branch, it indicates an error in user expectations or programmer error. Error out in that case. This lets us get rid of the dummy refspec which can never work as its zeroed out. In the cases where we did not find a default branch, we set HEAD detached immediately, which lets us refactor the "normal" path, removing `found_branch`.
Carlos Martín Nieto e128a1af 2014-09-02T13:10:19 clone: correct handling of an unborn HEAD If the remote does not advertise HEAD, then it is unborn and we cannot checkout that branch. Handle it the same way as an empty repo.
Carlos Martín Nieto 46254467 2014-08-29T15:10:15 clone: support remotes with references but no branches A repository can have any number of references which we're not interested in such as notes or tags. For the default branch calculation we only care about branches. Make the decision about the number of branches rather than the number of refs in general.
Vicent Marti 8f759ac0 2014-08-07T18:00:57 Merge pull request #2471 from jacquesg/compatibility-cleanup Compatibility/Portability cleanup
Jacques Germishuys 959a93e7 2014-07-13T11:50:49 Silence unused variables warnings
Vicent Marti 84a85d1b 2014-07-16T13:03:07 clone: should_clone? Of course we should clone. That's not the question
Edward Thomson 529fd30d 2014-07-08T15:45:50 Handle local file:/// paths on Windows Windows can't handle a path like `/c:/foo`; when turning file:/// URIs into local paths, we must strip the leading slash.
Carlos Martín Nieto 6812afaf 2014-06-30T21:36:38 clone: remote git_clone_into{,_local} from the public API As git_clone now has callbacks to configure the details of the repository and remote, remove the lower-level functions from the public API, as they lack some of the logic from git_clone proper.
Carlos Martín Nieto d58a64e9 2014-06-30T20:55:32 clone: add a callback for repository creation Analogously to the remote creation callback, provide a way for the user of git_clone() to create the repository with whichever options they desire via callback.
Philip Kelley 1697cd6f 2014-06-25T13:20:27 Improvements to git_transport extensibility git_remote_set_transport now takes a transport factory rather than a transport git_clone_options now allows the caller to specify a remote creation callback
Carlos Martín Nieto 18d7896c 2014-06-03T21:47:53 clone: re-use the local transport's path resolution Whe already worked out the kinks with the function used in the local transport. Expose it and make use of it in the local clone method instead of trying to work it out again.
Carlos Martín Nieto 2614819c 2014-05-28T11:28:57 clone: allow for linking in local clone If requested, git_clone_local_into() will try to link the object files instead of copying them. This only works on non-Windows (since it doesn't have this) when both are on the same filesystem (which are unix semantics).
Carlos Martín Nieto c1dbfcbb 2014-05-28T10:07:23 clone: add flag not to link
Carlos Martín Nieto 121b2673 2013-12-23T11:12:31 clone: add flags to override whether to perform a local clone
Carlos Martín Nieto a0b5f785 2013-12-22T15:39:54 clone: store the realpath when given a relative one A call like git_clone("./foo", "./foo1") writes origin's url as './foo', which makes it unusable, as they're relative to different things. Go with git's behaviour and store the realpath as the url.
Carlos Martín Nieto 4386d80b 2013-12-21T17:18:21 clone: perform a "local clone" when given a local path When git is given such a path, it will perform a "local clone", bypassing the git-aware protocol and simply copying over all objects that exist in the source. Copy this behaviour when given a local path.
Carlos Martín Nieto 4c4408c3 2014-05-22T12:28:39 Plug leaks and fix a C99-ism We have too many places where we repeat free code, so when adding the new free to the generic code, it didn't take for the local transport. While there, fix a C99-ism that sneaked through.
Carlos Martín Nieto 2a597116 2014-05-21T11:54:10 clone: get rid of head_info Since we no longer need to push data to callbacks, there's no need for this truct.
Carlos Martín Nieto cdb8a608 2014-05-21T11:51:33 clone: make use of the remote's default branch guessing Let's use the remote's default branch guessing instead of reinventing one ourselves with callbacks.
Albert Meltzer 60cdf495 2014-05-19T09:13:45 Minor fix for cmn/clone-into-mirror. A recently added check might skip initialization of old_fetchhead and go directly to cleanup. So, destruct in the opposite order of construction.
Carlos Martín Nieto 32332fcc 2014-05-19T14:15:40 clone: don't error out if the branch already exists We set up the current branch after we fetch from the remote. This means that the user's refspec may have already created this reference. It is therefore not an error if we cannot create the branch because it already exists. This allows for the user to replicate git-clone's --mirror option.
Carlos Martín Nieto 3c607685 2014-05-19T13:36:00 clone: duplicate the remote Instead of changing the user-provided remote, duplicate it so we can add the extra refspec without having to worry about unsetting it before returning.
Russell Belfer 702efc89 2014-04-30T10:57:42 Make init_options fns use unsigned ints and macro Use an unsigned int for the version and add a helper macro so the code is simplified (and so the error message is a common string).
Edward Thomson 1df8ad01 2014-03-06T16:00:52 clone: don't overwrite original error message
Ben Straub 6affd71f 2014-01-03T17:38:34 git_checkout_opts -> git_checkout_options
Matthew Bowen b9f81997 2014-03-05T21:49:23 Added function-based initializers for every options struct. The basic structure of each function is courtesy of arrbee.
Ben Straub c3ab1e5a 2014-02-04T20:38:13 Add reflog parameters to remote apis Also added a test for git_remote_fetch.

Carlos Martín Nieto bf522e08 2014-01-26T16:59:36 refspec: move to git_buf for outputting strings
Russell Belfer 8f1066a0 2013-12-10T16:02:24 Update clone doc and tests for callback return val Clone callbacks can return non-zero values to cancel the clone. This adds some tests to verify that this actually works and updates the documentation to be clearer that this can happen and that the return value will be propagated back by the clone function.
Russell Belfer 25e0b157 2013-12-06T15:07:57 Remove converting user error to GIT_EUSER This changes the behavior of callbacks so that the callback error code is not converted into GIT_EUSER and instead we propagate the return value through to the caller. Instead of using the giterr_capture and giterr_restore functions, we now rely on all functions to pass back the return value from a callback. To avoid having a return value with no error message, the user can call the public giterr_set_str or some such function to set an error message. There is a new helper 'giterr_set_callback' that functions can invoke after making a callback which ensures that some error message was set in case the callback did not set one. In places where the sign of the callback return value is meaningful (e.g. positive to skip, negative to abort), only the negative values are returned back to the caller, obviously, since the other values allow for continuing the loop. The hardest parts of this were in the checkout code where positive return values were overloaded as meaningful values for checkout. I fixed this by adding an output parameter to many of the internal checkout functions and removing the overload. This added some code, but it is probably a better implementation. There is some funkiness in the network code where user provided callbacks could be returning a positive or a negative value and we want to rely on that to cancel the loop. There are still a couple places where an user error might get turned into GIT_EUSER there, I think, though none exercised by the tests.
Russell Belfer dab89f9b 2013-12-04T21:22:57 Further EUSER and error propagation fixes This continues auditing all the places where GIT_EUSER is being returned and making sure to clear any existing error using the new giterr_user_cancel helper. As a result, places that relied on intercepting GIT_EUSER but having the old error preserved also needed to be cleaned up to correctly stash and then retrieve the actual error. Additionally, as I encountered places where error codes were not being propagated correctly, I tried to fix them up. A number of those fixes are included in the this commit as well.
Carlos Martín Nieto 359dce72 2013-11-02T00:05:32 remote: make _ls return the list directly The callback-based method of listing remote references dates back to the beginning of the network code's lifetime, when we didn't know any better. We need to keep the list around for update_tips() after disconnect() so let's make use of this to simply give the user a pointer to the array so they can write straightforward code instead of having to go through a callback.
Carlos Martín Nieto 266af6d8 2013-10-30T13:44:22 remote: don't allow such direct access to the refspecs Removing arbitrary refspecs makes things more complex to reason about. Instead, let the user set the fetch and push refspec list to whatever they want it to be.
Victor Garcia 40b99d05 2013-11-08T12:14:31 splitting funcionality in two methods to avoid ambiguity with NULL
Victor Garcia 0fe522d1 2013-11-07T14:16:20 allowing create remote with custom fetch spec
Russell Belfer 219d3457 2013-10-01T16:12:15 Initial iconv hookup for precomposed unicode This hooks up git_path_direach and git_path_dirload so that they will take a flag indicating if directory entry names should be tested and converted from decomposed unicode to precomposed form. This code will only come into play on the Apple platform and even then, only when certain types of filesystems are used. This involved adding a flag to these functions which involved changing a lot of places in the code. This was an opportunity to do a bit of code cleanup here and there, for example, getting rid of the git_futils_cleanupdir_r function in favor of a simple flag to git_futils_rmdir_r to not remove the top level entry. That ended up adding depth tracking during rmdir_r which led to a safety check for infinite directory recursion. Yay. This hasn't actually been tested on the Mac filesystems where the issue occurs. I still need to get test environment for that.
Carlos Martín Nieto 0e0cf787 2013-10-02T14:04:44 clone: put the callbacks struct directly in the clone options There's no need for this to be a pointer to somewhere else.
Carlos Martín Nieto fdc7e5e3 2013-09-20T23:14:12 clone: bring back NULL as defaults This wasremoved as part of the large culling a few commits ago.
Carlos Martín Nieto c833893c 2013-09-20T22:57:01 clone: re-allow using a custom remote name This is a small thing that by itself doesn't quite justify making the user use clone_into.
Carlos Martín Nieto eec1c1fe 2013-09-20T22:49:20 clone: const-ify checkout options The removal of many options which lead to the direct usage of the user's checkout options means we should make sure they remain const.
Carlos Martín Nieto b9bf5d70 2013-09-20T22:46:32 clone: re-add a way to ignore certificate errors This used to be done via transport flags, which was removed in a previous commit.
Carlos Martín Nieto 6ac15eff 2013-09-20T22:34:05 clone: remove more options from basic clone The basic clone function is there to make it easy to create a "normal" clone. Remove a bunch of options that are about changing the remote's configuration.
Carlos Martín Nieto e3a92f0d 2013-09-17T05:31:34 clone: implement git_clone on top of git_clone_into Unify the code bases.
Carlos Martín Nieto c8dbec48 2013-09-16T18:42:53 clone: remove the autotag option Downloading all tags is part of what makes it a clone instead of simply a fetch.
Carlos Martín Nieto fe3a40a4 2013-09-16T16:54:37 remote: add a convenience 'fetch' function.
Carlos Martín Nieto d19870d9 2013-09-16T05:10:55 clone: implement git_clone_into This allows you to set up the repository and remote as you which to have them before performing the clone operation.
Carlos Martín Nieto e3c131c5 2013-09-16T05:02:25 remote: move the credentials callback to the struct Move this one as well, letting us have a single way of setting the callbacks for the remote, and removing fields from the clone options.
Carlos Martín Nieto d31402a3 2013-09-16T04:20:05 remote: put the _download() callback with the others The text progress and update_tips callbacks are already part of the struct, which was meant to unify the callback setup, but the download one was left out.
Carlos Martín Nieto 605da51a 2013-09-17T09:50:30 No such thing as an orphan branch Unfortunately git-core uses the term "unborn branch" and "orphan branch" interchangeably. However, "orphan" is only really there for the checkout command, which has the `--orphan` option so it doesn't actually create the branch. Branches never have parents, so the distinction of a branch with no parents is odd to begin with. Crucially, the error messages deal with unborn branches, so let's use that.

Russell Belfer 55ededfd 2013-07-01T10:21:14 Make refspec_transform paranoid about arguments
Russell Belfer 114f5a6c 2013-06-10T10:10:39 Reorganize diff and add basic diff driver This is a significant reorganization of the diff code to break it into a set of more clearly distinct files and to document the new organization. Hopefully this will make the diff code easier to understand and to extend. This adds a new `git_diff_driver` object that looks of diff driver information from the attributes and the config so that things like function content in diff headers can be provided. The full driver spec is not implemented in the commit - this is focused on the reorganization of the code and putting the driver hooks in place. This also removes a few #includes from src/repository.h that were overbroad, but as a result required extra #includes in a variety of places since including src/repository.h no longer results in pulling in the whole world.

Carlos Martín Nieto 2b562c3a 2013-05-04T16:32:58 refs: remove the OID/SYMBOLIC filtering Nobody should ever be using anything other than ALL at this level, so remove the option altogether. As part of this, git_reference_foreach_glob is now implemented in the frontend using an iterator. Backends will later regain the ability of doing the glob filtering in the backend.

Carlos Martín Nieto bc6374ea 2013-04-20T18:49:11 remote: allow querying for refspecs Introduce git_remote_{fetch,push}_refspecs() to get a list of refspecs from the remote and rename the refspec-adding functions to a less silly name. Use this instead of the vector index hacks in the tests.
Carlos Martín Nieto 4330ab26 2013-04-20T04:43:28 remote: handle multiple refspecs A remote can have a multitude of refspecs. Up to now our git_remote's have supported a single one for each fetch and push out of simplicity to get something working. Let the remotes and internal code know about multiple remotes and get the tests passing with them. Instead of setting a refspec, the external users can clear all and add refspecs. This should be enough for most uses, though we're still missing a querying function.

nulltoken d1aee477 2013-01-06T15:09:27 clone: Fix a memory leak
Sascha Cunz 2ba6f3c7 2013-01-06T14:30:52 Allow to clone repositories that don't have a `master` branch Before this, we error out from `reference_matches_remote_head` if the reference we're searching for does not exist. Since we explicitly check if master is existing in `update_head_to_remote` and error out if it doesn't, a repository without master branch could not be cloned. In fact this was later clobbered by what is fixed in #1194. However, this patch introduces a `found` member in `head_info` and sets it accordingly. That also saves us from checking the string length of `branchname` a few times.
