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.
73dce1f6	2015-03-16T18:57:57	checkout: allow baseline to be specified as index Allow the baseline to be specified as an index, so that users need not write their index to a tree just to checkout with that as the baseline.
4beab1f8	2015-03-31T16:29:35	checkout: break case-changes into delete/add When checking out with a case-insensitive working directory, we want to change the case of items in the working directory to reflect changes that occured in the checkout target. Diff now has an option to break case-changing renames into delete/add.
05f69012	2015-03-31T16:28:13	checkout: remove blocking dir when FORCEd
3520c970	2015-03-27T15:39:28	Revert "Always checkout with case sensitive iterator" This reverts commit 40d791545abfb3cb71553a27dc64129e1a9bec28.
69f0032b	2015-04-28T12:40:20	Fix some build warnings In checkout.c and filter.c we were casting a sub struct to a parent struct which breaks the strict aliasing rules in C. However we can use .parent or .base to access the parent struct to avoid the build warnings. In remote.c the local variable error was not initialized or updated in some cases. For unintialized error a build warning will be generated. So always keep error variable up-to-date.
d3282680	2015-04-20T23:41:04	Fix index-adding functions to know when to trust filemodes. The idea...sometimes, a filemode is user-specified via an explicit git_index_entry. In this case, believe the user, always. Sometimes, it is instead built up by statting the file system. In those cases, go with the existing logic we have to determine whether the file system supports all filemodes and symlinks, and make the best guess. On file systems which have full filemode and symlink support, this commit should make no difference. On others (most notably Windows), this will fix problems things like: * git_index_add and git_index_add_frombuffer() should be believed. * As a consequence, git_checkout_tree should make the filemodes in the index match the ones in the tree. * And diffs with GIT_DIFF_UPDATE_INDEX don't write the wrong filemodes. * And merges, and probably other downstream stuff now fixed, too. This makes my previous changes to checkout.c unnecessary, so they are now reverted. Also, added a test for index_entry permissions from git_index_add and git_index_add_frombuffer, both of which failed before these changes.
6598aa7e	2015-04-16T14:10:34	Oops...need bitwise, not logical negation.
67db2bde	2015-03-10T12:02:45	Fix git_checkout_tree() to do index filemodes correctly on Windows. git_checkout_tree() has some fallback behaviors for file systems which don't have full support of filemodes. Generally works fine, but if a given file had a change of type from a 0644 to 0755 (i.e., you add executable permissions), the fallback behavior incorrectly triggers when writing hte updated index. This would cause a git_checkout_tree() command, even with the GIT_CHECKOUT_FORCE option set, to leave a dirty index on Windows. Also added checks to an existing test to catch this case.

3cda9cf2	2015-03-23T11:30:30	checkout: report correct invalid path
9a97f49e	2014-12-21T15:31:03	config: borrow refcounted references This changes the get_entry() method to return a refcounted version of the config entry, which you have to free when you're done. This allows us to avoid freeing the memory in which the entry is stored on a refresh, which may happen at any time for a live config. For this reason, get_string() has been forbidden on live configs and a new function get_string_buf() has been added, which stores the string in a git_buf which the user then owns. The functions which parse the string value takea advantage of the borrowing to parse safely and then release the entry.
96b82b11	2015-02-14T11:44:05	checkout: remove `GIT_CHECKOUT_SAFE_CREATE` as a strategy
e6da3e44	2015-02-14T10:33:06	checkout: upgrade to `SAFE_CREATE` when no index file When the repository does not contain an index, emulate git's behavior and upgrade to `SAFE_CREATE`. This allows us to check out repositories created with `git clone --no-checkout`.
9c9aa1ba	2015-02-19T11:32:55	filter: take `temp_buf` in `git_filter_options`
d05218b0	2015-02-19T11:25:26	filter: add `git_filter_list__load_ext` Refactor `git_filter_list__load_with_attr_reader` into `git_filter_list__load_ext`, which takes a `git_filter_options`.
795eaccd	2015-02-19T11:09:54	git_filter_opt_t -> git_filter_flag_t For consistency with the rest of the library, where an opt is an options structure.

646364e7	2015-02-17T20:25:31	checkout: maintain temporary buffer for filters Let the filters use the checkout data's temporary buffer, instead of having to allocate new buffers each time.
e78f5c9f	2015-01-22T16:11:36	checkout: stream the blob into the filters Use the new streaming filter API during checkout.
c8e02b87	2015-02-15T21:07:05	Remove extra semicolon outside of a function Without this change, compiling with gcc and pedantic generates warning: ISO C does not allow extra ‘;’ outside of a function.
8639ea5f	2015-01-17T22:47:03	checkout: introduce GIT_CHECKOUT_DONT_WRITE_INDEX
500ec543	2015-02-03T01:46:01	checkout: hold seen dir paths in a map
9f779aac	2015-01-29T14:40:55	attrcache: don't re-read attrs during checkout During checkout, assume that the .gitattributes files aren't modified during the checkout. Instead, create an "attribute session" during checkout. Assume that attribute data read in the same checkout "session" hasn't been modified since the checkout started. (But allow subsequent checkouts to invalidate the cache.) Further, cache nonexistent git_attr_file data even when .gitattributes files are not found to prevent re-scanning for nonexistent files.
11888039	2015-01-23T00:18:42	checkout: free last created directory
e74340b0	2015-01-14T18:47:00	checkout: remove files before writing new ones On case insensitive filesystems, we may have files in the working directory that case fold to a name we want to write. Remove those files (by default) so that we will not end up with a filename that has the unexpected case.
c2dee0fc	2015-01-14T13:20:21	checkout: drop newline in error message
b4cbd67f	2015-01-13T13:02:58	checkout: don't recreate previous directory Don't bother trying to recreate the previously created directory during checkout, for a modest reduction in the number of stats.
1fbfcdfc	2015-01-12T15:48:53	git_path_join_unrooted: return base len The documentation for `git_path_join_unrooted` states that the base length will be returned, so that consumers like checkout know where to start creating directories instead of always creating directories at the directory root.
1d50b364	2015-01-12T16:16:27	checkout: introduce git_checkout_perfdata Checkout can now provide performance data about the number of (some) syscalls performed using an optional callback.
40d79154	2014-05-09T19:32:52	Always checkout with case sensitive iterator On a case-insensitive filesystem, we need to deal with case-changing renames (eg, foo -> FOO) by removing the old and adding the new, exactly as if we were on a case-sensitive filesystem. Update the `checkout::tree::can_cancel_checkout_from_notify` test, now that notifications are always sent case sensitively.
a64119e3	2014-11-25T18:13:00	checkout: disallow bad paths on win32 Disallow: 1. paths with trailing dot 2. paths with trailing space 3. paths with trailing colon 4. paths that are 8.3 short names of .git folders ("GIT~1") 5. paths that are reserved path names (COM1, LPT1, etc). 6. paths with reserved DOS characters (colons, asterisks, etc) These paths would (without \\?\ syntax) be elided to other paths - for example, ".git." would be written as ".git". As a result, writing these paths literally (using \\?\ syntax) makes them hard to operate with from the shell, Windows Explorer or other tools. Disallow these.
692c0408	2014-11-09T08:09:25	Fixed a couple Clang warnings
62a617dc	2014-11-06T16:16:46	iterator: submodules are determined by an index or tree We cannot know from looking at .gitmodules whether a directory is a submodule or not. We need the index or tree we are comparing against to tell us. Otherwise we have to assume the entry in .gitmodules is stale or otherwise invalid. Thus we pass the index of the repository into the workdir iterator, even if we do not want to compare against it. This follows what git does, which even for `git diff <tree>`, it will consider staged submodules as such.
2d24816b	2014-11-06T18:49:37	checkout_index: Remove stage 0 when checking out conflicts
9f664347	2014-11-06T14:40:21	checkout_index: remove conflicts when checking out new files
55cb4999	2014-10-23T19:05:02	config: remove the refresh function and backend field We have been refreshing on read and write for a while now, so git_config_refresh() is at best a no-op, and might just end up wasting cycles.

5e2cf2ca	2014-10-10T13:22:11	Ensure filters (i.e. CRLF) are applied when checking out conflict content
7d0ab0fa	2014-07-22T15:08:24	Merge remote-tracking branch 'origin/master' into fix-git-status-list-new-unreadable-folder
967f5a76	2014-05-23T14:50:51	git_checkout_index: checkout other indexes git_checkout_index can now check out other git_index's (that are not necessarily the repository index). This allows checkout_index to use the repository's index for stat cache information instead of the index data being checked out. git_merge and friends now check out their indexes directly instead of trying to blend it into the running index.
61bef72d	2014-05-20T23:57:40	Start adding GIT_DELTA_UNREADABLE and GIT_STATUS_WT_UNREADABLE.
5269008c	2014-05-06T16:01:49	Add filter options and ALLOW_UNSAFE Diff and status do not want core.safecrlf to actually raise an error regardless of the setting, so this extends the filter API with an additional options flags parameter and adds a flag so that filters can be applied with GIT_FILTER_OPT_ALLOW_UNSAFE, indicating that unsafe filter application should be downgraded from a failure to a warning.
bc91347b	2014-04-30T11:16:31	Fix remaining init_options inconsistencies There were a couple of "init_opts()" functions a few more cases of structure initialization that I somehow missed.
94fb4aad	2014-04-28T14:48:41	Add diff option to update index stat cache When diff is scanning the working directory, if it finds a file where it is not sure if the index entry matches the working dir, it will recalculate the OID (which is pretty expensive). This adds a new flag to diff so that if the OID calculation finds that the file actually has not changed (i.e. just the modified time was altered or such), then it will refresh the stat cache in the index so that future calls to diff will not have to check the oid again.
0fc8e1f6	2014-04-28T14:34:55	Lay groundwork for updating stat cache in diff This reorganized the diff OID calculation to make it easier to correctly update the stat cache during a diff once the flags to do so are enabled. This includes marking the path of a git_index_entry as const so we can make a "fake" git_index_entry with a "const char *" path and not get warnings. I was a little surprised at how unobtrusive this change was, but I think it's probably a good thing.
240f4af3	2014-04-28T14:04:29	Add build option for diff internal statistics
219c89d1	2014-04-23T16:28:45	Treat ignored, empty, and untracked dirs different In the iterator, distinguish between ignores and empty directories so that diff and status can ignore empty directories, but checkout and stash can treat them as untracked items.
37da3685	2014-04-22T21:51:54	Make checkout match diff for untracked/ignored dir When diff finds an untracked directory, it emulates Git behavior by looking inside the directory to see if there are any untracked items inside it. If there are only ignored items inside the dir, then diff considers it ignored, even if there is no direct ignore rule for it. Checkout was not copying this behavior - when it found an untracked directory, it just treated it as untracked. Unfortunately, when combined with GIT_CHECKOUT_REMOVE_UNTRACKED, this made is seem that checkout (and stash, which uses checkout) was removing ignored items when you had only asked it to remove untracked ones. This commit moves the logic for advancing past an untracked dir while scanning for non-ignored items into an iterator helper fn, and uses that for both diff and checkout.
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.
52bb0476	2014-03-14T13:53:15	Clean up index snapshot function naming Clear up some of the various "find" functions and the snapshot API naming to be things I like more.
3dbee456	2014-02-07T14:10:35	Some index internals refactoring Again, laying groundwork for some index iterator changes, this contains a bunch of code refactorings for index internals that should make it easier down the line to add locking around index modifications. Also this removes the redundant prefix_position function and fixes some potential memory leaks.
c67fd4c9	2014-02-07T11:20:36	Some vector utility tweaks This is just laying some groundwork for internal index changes that I'm working on.
49653665	2014-04-02T18:21:41	checkout: Fix submodule_is_config_only's return value
591e8295	2014-03-25T16:52:01	Fix submodule leaks and invalid references This cleans up some places I missed that could hold onto submodule references and cleans up the way in which the repository cache is both reloaded and released so that existing submodule references aren't destroyed inappropriately.
a15c7802	2014-03-25T09:14:48	Make submodules externally refcounted `git_submodule` objects were already refcounted internally in case the submodule name was different from the path at which it was stored. This makes that refcounting externally used as well, so `git_submodule_lookup` and `git_submodule_add_setup` return an object that requires a `git_submodule_free` when done.
05d47768	2014-03-10T22:30:41	Introduce git_merge_file for consumers
6affd71f	2014-01-03T17:38:34	git_checkout_opts -> git_checkout_options
b9f81997	2014-03-05T21:49:23	Added function-based initializers for every options struct. The basic structure of each function is courtesy of arrbee.
25babd02	2014-01-30T11:38:59	Fix checkout NONE to not remove file If you are checking out NONE, then don't remove.
71ae7601	2014-01-30T11:30:16	Force explicit remove of files instead of defer The checkout code used to defer removal of "blocking" files in checkouts until the blocked item was actually being written (since we have already checked that the removing the block is acceptable according to the update rules). Unfortunately, this resulted in an intermediate index state where both the blocking and new items were in the index which is no longer allowed. Now we just remove the blocking item in the first pass so it never needs to coexist. In cases where there are typechanges, this could result in a bit more churn of removing and recreating intermediate directories, but I'm going to assume that is an unusual case and the churn will not be too costly.
9950bb4e	2014-01-24T20:23:17	diff: rename the file's 'oid' to 'id' In the same vein as the previous commits in this series.
d541170c	2014-01-24T11:36:41	index: rename an entry's id to 'id' This was not converted when we converted the rest, so do it now.
ab4bcc03	2014-01-22T14:14:37	Plug a small memory leak
e8b81c69	2014-01-22T13:24:32	Preserve tree filemode in index during checkout Don't try to determine whether the system supports file modes when putting the tree data in the index during checkout. The tree's mode is canonical and did not come from stat(2) in the first place.
0ef19fe1	2014-01-20T17:13:55	Merge submodules
6891a862	2014-01-19T18:12:22	Load merge.conflictstyle setting from config
e651e8e2	2014-01-19T15:05:08	Introduce diff3 mode for checking out conflicts
6b92c99b	2014-01-19T01:20:25	Don't try to merge binary files
c1d648c5	2014-01-08T18:29:42	merge_file should use more aggressive levels The default merge_file level was XDL_MERGE_MINIMAL, which will produce conflicts where there should not be in the case where both sides were changed identically. Change the defaults to be more aggressive (XDL_MERGE_ZEALOUS) which will more aggressively compress non-conflicts. This matches git.git's defaults. Increase testing around reverting a previously reverted commit to illustrate this problem.
bf4a577c	2013-12-13T10:10:32	Overwrite ignored directories on checkout
81a2012d	2013-12-12T11:30:50	Overwrite ignored files on checkout
9cfce273	2013-12-12T12:11:38	Cleanups, renames, and leak fixes This renames git_vector_free_all to the better git_vector_free_deep and also contains a couple of memory leak fixes based on valgrind checks. The fixes are specifically: failure to free global dir path variables when not compiled with threading on and failure to free filters from the filter registry that had not be initialized fully.
cbd04896	2013-12-10T14:38:35	Fix checkout notify callback docs and tests The checkout notify callback behavior on non-zero return values was not being tested. This adds tests, fixes a bug with positive values, and clarifies the documentation to make it clear that the checkout can be canceled via this mechanism.
26c1cb91	2013-12-09T09:44:03	One more rename/cleanup for callback err functions
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.
fcd324c6	2013-12-06T15:04:31	Add git_vector_free_all There are a lot of places that we call git__free on each item in a vector and then call git_vector_free on the vector itself. This just wraps that up into one convenient helper function.
96869a4e	2013-12-03T16:45:39	Improve GIT_EUSER handling This adds giterr_user_cancel to return GIT_EUSER and clear any error message that is sitting around. As a result of using that in places, we need to be more thorough with capturing errors that happen inside a callback when used internally. To help with that, this also adds giterr_capture and giterr_restore so that when we internally use a foreach-type function that clears errors and converts them to GIT_EUSER, it is easier to restore not just the return value, but the actual error message text.
1d3a8aeb	2013-11-04T18:28:57	move mode_t to filebuf_open instead of _commit
44acdd1f	2013-11-04T08:09:58	Merge pull request #1937 from scunz/checkout_assert Don't assert in git_checkout_tree
7b3959b2	2013-11-02T03:45:32	Checkout: git_checkout_head is git_checkout_tree without a treeish The last commit taught git_checkout_tree to actually do something meaningfull, when treeish was NULL. This lets us rewrite git_checkout_head to simply call git_checkout_tree without giving it a treeish.
35221441	2013-11-02T03:43:34	Checkout: Don't assert if treeish is NULL In git_checkout_tree, the first check tests if either repo or treeish is NULL and says that eithor of them has to have a valid value. But there is no code to handle the treeish == NULL case. So, do something meaningful in that case: use HEAD instead.
10749f6c	2013-11-02T03:20:05	Checkout: Unifiy const-ness of `opts` parameter Since all 3 checkout APIs perform the same operation with the options, all of them should use the same const-ness.
8e5a8ef8	2013-11-01T09:51:01	Convert git_index_read to have a "force" flag This is a little more intuitive than the turned-around option that I originally wrote.
4bf630b6	2013-10-31T14:36:52	Make diff and status perform soft index reload This changes `git_index_read` to have two modes - a hard index reload that always resets the index to match the on-disk data (which was the old behavior) and a soft index reload that uses the timestamp / file size information and only replaces the index data if the file on disk has been modified. This then updates the git_status code to do a soft reload unless the new GIT_STATUS_OPT_NO_REFRESH flag is passed in. This also changes the behavior of the git_diff functions that use the index so that when an index is not explicitly passed in (i.e. when the functions call git_repository_index for you), they will also do a soft reload for you. This intentionally breaks the file signature of git_index_read because there has been some confusion about the behavior previously and it seems like all existing uses of the API should probably be examined to select the desired behavior.
95352b70	2013-11-01T16:55:20	checkout: Remove unused vector

7fa73de1	2013-09-23T17:52:40	Move functions in checkout_conflicts to checkout.c It seemed exceptionally silly to have a split there where no split needed to be.
216f97e4	2013-09-23T09:47:47	Two-step conflict checkout (load / perform) Move conflict handling into two steps: load the conflicts and then apply the conflicts. This is more compatible with the existing checkout implementation and makes progress reporting more sane.

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.
14997dc5	2013-10-08T12:45:43	More filemode cleanups for FAT on MacOS This cleans up some additional issues. The main change is that on a filesystem that doesn't support mode bits, libgit2 will now create new blobs with GIT_FILEMODE_BLOB always instead of being at the mercy to the filesystem driver to report executable or not. This means that if "core.filemode" lies and claims that filemode is not supported, then we will ignore the executable bit from the filesystem. Previously we would have allowed it. This adds an option to the new git_repository_reset_filesystem to recurse through submodules if desired. There may be other types of APIs that would like a "recurse submodules" option, but this one is particularly useful. This also has a number of cleanups, etc., for related things including trying to give better error messages when problems come up from the filesystem. For example, the FAT filesystem driver on MacOS appears to return errno EINVAL if you attempt to write a filename with invalid UTF-8 in it. We try to capture that with a better error message now.
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.
0e32635f	2013-09-12T14:47:15	Move binary check to CRLF filter itself Checkout should not reject binary files from filters, as a filter may actually wish to operate on binary files. The CRLF filter should reject binary files itself if it wishes to. Moreover, the CRLF filter requires this logic so that users can emulate the checkout data in their odb -> workdir filtering. Conflicts: src/checkout.c src/crlf.c
a9f51e43	2013-09-11T22:00:36	Merge git_buf and git_buffer This makes the git_buf struct that was used internally into an externally available structure and eliminates the git_buffer. As part of that, some of the special cases that arose with the externally used git_buffer were blended into the git_buf, such as being careful about git_buf objects that may have a NULL ptr and allowing for bufs with a valid ptr and size but zero asize as a way of referring to externally owned data.
4b11f25a	2013-09-11T16:38:33	Add ident filter This adds the ident filter (that knows how to replace $Id$) and tweaks the filter APIs and code so that git_filter_source objects actually have the updated OID of the object being filtered when it is a known value.
2a7d224f	2013-09-10T16:33:32	Extend public filter api with filter lists This moves the git_filter_list into the public API so that users can create, apply, and dispose of filter lists. This allows more granular application of filters to user data outside of libgit2 internals. This also converts all the internal usage of filters to the public APIs along with a few small tweaks to make it easier to use the public git_buffer stuff alongside the internal git_buf.

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.

Fix some build warnings In checkout.c and filter.c we were casting a sub struct to a parent struct which breaks the strict aliasing rules in C. However we can use .parent or .base to access the parent struct to avoid the build warnings. In remote.c the local variable error was not initialized or updated in some cases. For unintialized error a build warning will be generated. So always keep error variable up-to-date.

Fix index-adding functions to know when to trust filemodes. The idea...sometimes, a filemode is user-specified via an explicit git_index_entry. In this case, believe the user, always. Sometimes, it is instead built up by statting the file system. In those cases, go with the existing logic we have to determine whether the file system supports all filemodes and symlinks, and make the best guess. On file systems which have full filemode and symlink support, this commit should make no difference. On others (most notably Windows), this will fix problems things like: * git_index_add and git_index_add_frombuffer() should be believed. * As a consequence, git_checkout_tree should make the filemodes in the index match the ones in the tree. * And diffs with GIT_DIFF_UPDATE_INDEX don't write the wrong filemodes. * And merges, and probably other downstream stuff now fixed, too. This makes my previous changes to checkout.c unnecessary, so they are now reverted. Also, added a test for index_entry permissions from git_index_add and git_index_add_frombuffer, both of which failed before these changes.

Fix git_checkout_tree() to do index filemodes correctly on Windows. git_checkout_tree() has some fallback behaviors for file systems which don't have full support of filemodes. Generally works fine, but if a given file had a change of type from a 0644 to 0755 (i.e., you add executable permissions), the fallback behavior incorrectly triggers when writing hte updated index. This would cause a git_checkout_tree() command, even with the GIT_CHECKOUT_FORCE option set, to leave a dirty index on Windows. Also added checks to an existing test to catch this case.

config: borrow refcounted references This changes the get_entry() method to return a refcounted version of the config entry, which you have to free when you're done. This allows us to avoid freeing the memory in which the entry is stored on a refresh, which may happen at any time for a live config. For this reason, get_string() has been forbidden on live configs and a new function get_string_buf() has been added, which stores the string in a git_buf which the user then owns. The functions which parse the string value takea advantage of the borrowing to parse safely and then release the entry.

iterator: submodules are determined by an index or tree We cannot know from looking at .gitmodules whether a directory is a submodule or not. We need the index or tree we are comparing against to tell us. Otherwise we have to assume the entry in .gitmodules is stale or otherwise invalid. Thus we pass the index of the repository into the workdir iterator, even if we do not want to compare against it. This follows what git does, which even for `git diff <tree>`, it will consider staged submodules as such.

Add diff option to update index stat cache When diff is scanning the working directory, if it finds a file where it is not sure if the index entry matches the working dir, it will recalculate the OID (which is pretty expensive). This adds a new flag to diff so that if the OID calculation finds that the file actually has not changed (i.e. just the modified time was altered or such), then it will refresh the stat cache in the index so that future calls to diff will not have to check the oid again.

This includes marking the path of a git_index_entry as const so we can make a "fake" git_index_entry with a "const char *" path and not get warnings. I was a little surprised at how unobtrusive this change was, but I think it's probably a good thing.

Treat ignored, empty, and untracked dirs different In the iterator, distinguish between ignores and empty directories so that diff and status can ignore empty directories, but checkout and stash can treat them as untracked items.

37da3685

2014-04-22T21:51:54

Make checkout match diff for untracked/ignored dir When diff finds an untracked directory, it emulates Git behavior by looking inside the directory to see if there are any untracked items inside it. If there are only ignored items inside the dir, then diff considers it ignored, even if there is no direct ignore rule for it. Checkout was not copying this behavior - when it found an untracked directory, it just treated it as untracked. Unfortunately, when combined with GIT_CHECKOUT_REMOVE_UNTRACKED, this made is seem that checkout (and stash, which uses checkout) was removing ignored items when you had only asked it to remove untracked ones. This commit moves the logic for advancing past an untracked dir while scanning for non-ignored items into an iterator helper fn, and uses that for both diff and checkout.

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.

Force explicit remove of files instead of defer The checkout code used to defer removal of "blocking" files in checkouts until the blocked item was actually being written (since we have already checked that the removing the block is acceptable according to the update rules). Unfortunately, this resulted in an intermediate index state where both the blocking and new items were in the index which is no longer allowed. Now we just remove the blocking item in the first pass so it never needs to coexist. In cases where there are typechanges, this could result in a bit more churn of removing and recreating intermediate directories, but I'm going to assume that is an unusual case and the churn will not be too costly.

One more rename/cleanup for callback err functions

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.

Improve GIT_EUSER handling This adds giterr_user_cancel to return GIT_EUSER and clear any error message that is sitting around. As a result of using that in places, we need to be more thorough with capturing errors that happen inside a callback when used internally. To help with that, this also adds giterr_capture and giterr_restore so that when we internally use a foreach-type function that clears errors and converts them to GIT_EUSER, it is easier to restore not just the return value, but the actual error message text.

2013-10-31T14:36:52

Make diff and status perform soft index reload This changes `git_index_read` to have two modes - a hard index reload that always resets the index to match the on-disk data (which was the old behavior) and a soft index reload that uses the timestamp / file size information and only replaces the index data if the file on disk has been modified. This then updates the git_status code to do a soft reload unless the new GIT_STATUS_OPT_NO_REFRESH flag is passed in. This also changes the behavior of the git_diff functions that use the index so that when an index is not explicitly passed in (i.e. when the functions call git_repository_index for you), they will also do a soft reload for you. This intentionally breaks the file signature of git_index_read because there has been some confusion about the behavior previously and it seems like all existing uses of the API should probably be examined to select the desired behavior.

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.

More filemode cleanups for FAT on MacOS This cleans up some additional issues. The main change is that on a filesystem that doesn't support mode bits, libgit2 will now create new blobs with GIT_FILEMODE_BLOB always instead of being at the mercy to the filesystem driver to report executable or not. This means that if "core.filemode" lies and claims that filemode is not supported, then we will ignore the executable bit from the filesystem. Previously we would have allowed it. This adds an option to the new git_repository_reset_filesystem to recurse through submodules if desired. There may be other types of APIs that would like a "recurse submodules" option, but this one is particularly useful. This also has a number of cleanups, etc., for related things including trying to give better error messages when problems come up from the filesystem. For example, the FAT filesystem driver on MacOS appears to return errno EINVAL if you attempt to write a filename with invalid UTF-8 in it. We try to capture that with a better error message now.

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.

Move binary check to CRLF filter itself Checkout should not reject binary files from filters, as a filter may actually wish to operate on binary files. The CRLF filter should reject binary files itself if it wishes to. Moreover, the CRLF filter requires this logic so that users can emulate the checkout data in their odb -> workdir filtering. Conflicts: src/checkout.c src/crlf.c

Merge git_buf and git_buffer This makes the git_buf struct that was used internally into an externally available structure and eliminates the git_buffer. As part of that, some of the special cases that arose with the externally used git_buffer were blended into the git_buf, such as being careful about git_buf objects that may have a NULL ptr and allowing for bufs with a valid ptr and size but zero asize as a way of referring to externally owned data.

Add ident filter This adds the ident filter (that knows how to replace $Id$) and tweaks the filter APIs and code so that git_filter_source objects actually have the updated OID of the object being filtered when it is a known value.

Extend public filter api with filter lists This moves the git_filter_list into the public API so that users can create, apply, and dispose of filter lists. This allows more granular application of filters to user data outside of libgit2 internals. This also converts all the internal usage of filters to the public APIs along with a few small tweaks to make it easier to use the public git_buffer stuff alongside the internal git_buf.
