Edward Thomson f673e232 2018-12-27T13:47:34 git_error: use new names in internal APIs and usage Move to the `git_error` name in the internal API for error-related functions.
Edward Thomson 4919e495 2018-02-18T23:55:56 stash: use _an_ index not _the_ index Don't manipulate the repository's index during stash; instead, manipulate a temporary index and check it out. This allows us to use the checkout mechanism to update the workdir and the repository's index, and allows checkout to use its common mechanisms to write data and handle errors.
Patrick Steinhardt ecf4f33a 2018-02-08T11:14:48 Convert usage of `git_buf_free` to new `git_buf_dispose`
Etienne Samson cdd0bc2f 2018-03-26T18:44:13 checkout: change default strategy to SAFE As per #4200, our default is quite surprising to users that expect checkout to just "do the thing".
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.
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
Edward Thomson 9be638ec 2016-04-19T15:12:18 git_diff_generated: abstract generated diffs
Arthur Schreiber 3679ebae 2016-02-11T23:37:52 Horrible fix for #3173.
Edward Thomson ed1c6446 2015-07-28T11:41:27 iterator: use an options struct instead of args
Matthew Plough 768f8be3 2015-06-30T19:00:41 Fix #3094 - improve use of portable size_t/ssize_t format specifiers. The header src/cc-compat.h defines portable format specifiers PRIuZ, PRIdZ, and PRIxZ. The original report highlighted the need to use these specifiers in examples/network/fetch.c. For this commit, I checked all C source and header files not in deps/ and transitioned to the appropriate format specifier where appropriate.
Edward Thomson 149d5d8a 2015-06-29T15:17:58 stash: drop unused variable
Edward Thomson b7f5cb8d 2015-06-20T19:33:15 stash: stage new files when unstashing them Files that were new (staged additions) in the stash tree should be staged when unstashing, even when not applying the index.
Edward Thomson 82b1c93d 2015-06-20T13:44:22 stash: don't allow apply with staged changes
Edward Thomson 90177111 2015-06-23T16:27:33 stash: save the workdir file when deleted in index When stashing the workdir tree, examine the index as well. Using a mechanism similar to `git_diff_tree_to_workdir_with_index` allows us to determine that a file was added in the index and subsequently modified in the working directory. Without examining the index, we would erroneously believe that this file was untracked and fail to include it in the working directory tree. Use a slightly modified `git_diff_tree_to_workdir_with_index` in order to avoid some of the behavior custom to `git diff`. In particular, be sure to include the working directory side of a file when it was deleted in the index.
Pierre-Olivier Latour e35b947b 2015-06-21T01:06:20 Write modified index in git_stash_apply() Same as with git_stash_save(), there's no reason not to write the index to disk since it has been modified.
Edward Thomson 885b94aa 2015-05-28T15:26:13 Rename GIT_EMERGECONFLICT to GIT_ECONFLICT We do not error on "merge conflicts"; on the contrary, merge conflicts are a normal part of merging. We only error on "checkout conflicts", where a change exists in the index or the working directory that would otherwise be overwritten by performing the checkout. This *may* happen during merge (after the production of the new index that we're going to checkout) but it could happen during any checkout.
Carlos Martín Nieto 3e529e9d 2015-05-13T16:12:45 Fix a few leaks The interesting one is the notification macro, which was returning directly on a soft-abort instead of going through the cleanup.
Edward Thomson 44972873 2015-05-11T14:02:53 stash: propagate the error when writing a tree

Edward Thomson 90f8408d 2015-02-18T16:33:50 stash: ensure a reflog has entries
Edward Thomson d0dd3fce 2015-02-18T15:16:05 stash apply: check out a tree, not piecewise
Edward Thomson 7f26b1b9 2015-02-18T13:24:07 stash: use git_commit_summary for a summary
Pierre-Olivier Latour bf8dd3f5 2014-11-14T12:32:47 Added git_stash_apply() and git_stash_pop() APIs
Edward Thomson 018fdbb5 2015-03-03T10:08:28 Merge pull request #2913 from ethomson/stash_fixup stash: correctly stash wd modified/index deleted
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.
Edward Thomson 09866d6f 2015-02-18T11:26:03 stash: correctly stash wd modified/index deleted
Carlos Martín Nieto c327d5db 2014-10-09T16:29:30 transaction: rename lock() to lock_ref() This leaves space for future expansion to locking other resources without having to change the API for references.
Carlos Martín Nieto f99ca523 2014-06-30T06:38:45 stash: use a transaction to modify the reflog The stash is implemented as the refs/stash reference and its reflog. In order to modify the reflog, we need avoid races by making sure we're the only ones allowed to modify the reflog. We achieve this via the transactions API. Locking the reference gives us exclusive write access, letting us modify and write it without races.
Jacques Germishuys 7b7aa75f 2014-09-24T13:24:39 Recurse ignored directories when stashing
Arkady Shapkin 5cd81bb3 2014-09-03T01:01:25 Several CppCat warnings fixed
Russell Belfer 24d17de2 2014-04-02T12:07:27 Make stash and checkout ignore contained repos To emulate git, stash should not remove untracked git repositories inside the parent repo, and checkout's REMOVE_UNTRACKED should also skip over these items. `git stash` actually prints a warning message for these items. That should be possible with a checkout notify callback if you wanted to, although it would require a bit of extra logic as things are at the moment.

Jacques Germishuys 4636ca93 2014-03-04T12:22:27 Remove ignored files from the working directory if they were stashed
Carlos Martín Nieto 0b28217b 2014-01-15T12:51:31 refs: remove the _with_log differentiation Any well-behaved program should write a descriptive message to the reflog whenever it updates a reference. Let's make this more prominent by removing the version without the reflog parameters.
Vicent Marti 4e1f517c 2013-12-18T09:33:45 Merge pull request #1920 from libgit2/cmn/ref-with-log Reference operations with log
Russell Belfer 26c1cb91 2013-12-09T09:44:03 One more rename/cleanup for callback err functions
Russell Belfer c7b3e1b3 2013-12-06T15:42:20 Some callback error check style cleanups I find this easier to read...
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 8d5ec910 2013-11-23T14:13:01 refs: expose a way to ensure a ref has a log Sometimes (e.g. stash) we want to make sure that a log will be written, even if it's not in one of the standard locations. Let's make that easier.
Carlos Martín Nieto a57dd3b7 2013-11-13T18:15:20 reflog: integrate into the ref writing Whenever a reference is created or updated, we need to write to the reflog regardless of whether the user gave us a message, so we shouldn't leave that to the ref frontend, but integrate it into the backend. This also eliminates the race between ref update and writing to the reflog, as we protect the reflog with the ref lock. As an additional benefit, this reflog append on the backend happens by appending to the file instead of parsing and rewriting it.
Ben Straub 8f4a8b09 2013-10-28T06:20:28 Merge pull request #1802 from libgit2/cmn/reflog-backend Make reflog part of refdb
Russell Belfer 10672e3e 2013-10-15T15:10:07 Diff API cleanup This lays groundwork for separating formatting options from diff creation options. This groups the formatting flags separately from the diff list creation flags and reorders the options. This also tweaks some APIs to further separate code that uses patches from code that just looks at git_diffs.
Russell Belfer 3ff1d123 2013-10-11T14:51:54 Rename diff objects and split patch.h This makes no functional change to diff but renames a couple of the objects and splits the new git_patch (formerly git_diff_patch) into a new header file.
Carlos Martín Nieto b976f3c2 2013-08-19T13:01:49 reflog: move the reflog implementation into refdb_fs References and their logs are logically coupled, let's make it so in the code by moving the fs-based reflog implementation to live next to the fs-based refs one. As part of the change, make the function take names rather than references, as only the names are relevant when looking up and handling reflogs.
Justin Spahr-Summers 4fe0b0b3 2013-09-27T17:07:06 Never consider submodules for stashing
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.
Etienne Samson 2274993b 2013-07-09T12:52:25 Make the git_signature const in the stash API.
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.

Russell Belfer 6f58332f 2012-12-20T16:15:02 Fix use of uninitialized variable
Russell Belfer a6a82e1a 2012-12-19T15:06:40 Improve error propagation in stash Stash was sometimes obscuring the actual error code, replacing it with a -1 when there was more descriptive value. This updates stash to preserve the original error code more reliably along with a variety of other error handling tweaks. I believe this is an improvement, but arguably, preserving the underlying error code may result in values that are harder to interpret by the caller who does not understand the internals. Discussion is welcome!
Russell Belfer cf208031 2012-12-06T13:36:17 Rework checkout internals (again) I've tried to map out the detailed behaviors of checkout and make sure that we're handling the various cases correctly, along with providing options to allow us to emulate "git checkout" and "git checkout-index" with the various flags. I've thrown away flags in the checkout API that seemed like clutter and added some new ones. Also, I've converted the conflict callback to a general notification callback so we can emulate "git checkout" output and display "dirty" files. As of this commit, the new behavior is not working 100% but some of that is probably baked into tests that are not testing the right thing. This is a decent snapshot point, I think, along the way to getting the update done.
Russell Belfer 56c72b75 2012-12-17T11:00:53 Fix diff constructor name order confusion The diff constructor functions had some confusing names, where the "old" side of the diff was coming after the "new" side. This reverses the order in the function name to make it less confusing. Specifically... * git_diff_index_to_tree becomes git_diff_tree_to_index * git_diff_workdir_to_index becomes git_diff_index_to_workdir * git_diff_workdir_to_tree becomes git_diff_tree_to_workdir

Russell Belfer 793c4385 2012-11-20T16:36:06 Update diff callback param order This makes the diff functions that take callbacks both take the payload parameter after the callback function pointers and pass the payload as the last argument to the callback function instead of the first. This should make them consistent with other callbacks across the API.
Ben Straub 2508cc66 2012-11-18T21:38:08 Rename ref and reflog apis for consistency
nulltoken b15df1d9 2012-11-17T18:29:51 reflog: make entry_byindex() and drop() git compliant Passing 0 as the index now retrieves the most recent entry instead of the oldest one.
Russell Belfer bbe6dbec 2012-11-14T23:29:48 Add explicit git_index ptr to diff and checkout A number of diff APIs and the `git_checkout_index` API take a `git_repository` object an operate on the index. This updates them to take a `git_index` pointer explicitly and only fall back on the `git_repository` index if the index input is NULL. This makes it easier to operate on a temporary index.
Russell Belfer 5735bf5e 2012-11-13T13:58:29 Fix diff API to better parameter order The diff API is not in the parameter order one would expect from other libgit2 APIs. This fixes that.
Russell Belfer ad9a921b 2012-11-08T17:05:07 Rework checkout with new strategy options This is a major reworking of checkout strategy options. The checkout code is now sensitive to the contents of the HEAD tree and the new options allow you to update the working tree so that it will match the index content only when it previously matched the contents of the HEAD. This allows you to, for example, to distinguish between removing files that are in the HEAD but not in the index, vs just removing all untracked files. Because of various corner cases that arise, etc., this required some additional capabilities in rmdir and other utility functions. This includes the beginnings of an implementation of code to read a partial tree into the index based on a pathspec, but that is not enabled because of the possibility of creating conflicting index entries.
