81a2012d	2013-12-12T11:30:50	Overwrite ignored files on checkout
452c7de6	2013-12-12T14:16:40	Add git_treebuilder_insert test and clarify doc This wasn't being tested and since it has a callback, I fixed it even though the return value of this callback is not treated like any of the other callbacks in the API.
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.
7697e541	2013-12-11T15:02:20	Test cancel from indexer progress callback This adds tests that try canceling an indexer operation from within the progress callback. After writing the tests, I wanted to run this under valgrind and had a number of errors in that situation because mmap wasn't working. I added a CMake option to force emulation of mmap and consolidated the Amiga-specific code into that new place (so we don't actually need separate Amiga code now, just have to turn on -DNO_MMAP). Additionally, I made the indexer code propagate error codes more reliably than it used to.
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.
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.
19853bdd	2013-12-10T13:01:34	Update git_blob_create_fromchunks callback behavr The callback to supply data chunks could return a negative value to stop creation of the blob, but we were neither using GIT_EUSER nor propagating the return value. This makes things use the new behavior of returning the negative value back to the user.
373cf6a9	2013-12-09T10:17:47	Update docs for new callback return value behavior
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.
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.
9f77b3f6	2013-11-25T14:21:34	Add config read fns with controlled error behavior This adds `git_config__lookup_entry` which will look up a key in a config and return either the entry or NULL if the key was not present. Optionally, it can either suppress all errors or can return them (although not finding the key is not an error for this function). Unlike other accessors, this does not normalize the config key string, so it must only be used when the key is known to be in normalized form (i.e. all lower-case before the first dot and after the last dot, with no invalid characters). This also adds three high-level helper functions to look up config values with no errors and a fallback value. The three functions are for string, bool, and int values, and will resort to the fallback value for any error that arises. They are: * `git_config__get_string_force` * `git_config__get_bool_force` * `git_config__get_int_force` None of them normalize the config `key` either, so they can only be used for internal cases where the key is known to be in normal format.

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.

97ad85b8	2013-12-02T13:30:05	Add GIT_DIFF_FIND_DELETE_UNMODIFIED flag When doing copy detection, it is often necessary to include UNMODIFIED records in the git_diff so they are available as source records for GIT_DIFF_FIND_COPIES_FROM_UNMODIFIED. Yet in the final diff, often you will not want to have these UNMODIFIED records. This adds a flag which marks these UNMODIFIED records for deletion from the diff list so they will be removed after the rename detect phase is over.
13c9e44a	2013-11-14T19:41:09	reflog: remove git_reflog_append_to() This was a convenience method for the refs front-end to do the reflog writing. This is now done in the backend and it has no more reason for being.
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.
110df893	2013-11-13T13:36:37	refdb: add a `message` parameter for appending to the log This is as yet unused.

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.
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.

This is helpful when you need to call some code that may alter the error and you want to restore it later on and/or report it via some other mechanism.

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.
2f03050f	2013-10-26T16:21:31	remote: download HEAD when no refspecs are given The correct behaviour when a remote has no refspecs (e.g. a URL from the command-line) is to download the remote's HEAD. Let's do that. This fixes #1261.
a5c16f3c	2013-11-01T10:18:03	Add git_diff_options_init helper Sometimes the static initializer for git_diff_options cannot be used and since setting them to all zeroes doesn't actually work quite right, this adds a new helper for that situation. This also adds an explicit new value to the submodule settings options to be used when those enums need static initialization.
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.
ac5e507c	2013-11-01T09:31:52	Merge pull request #1918 from libgit2/cmn/indexer-naming indexer: remove the stream infix
3793fa9b	2013-10-31T01:08:50	Fix saving remotes with several fetch/push ref specs. At some moment git_config_delete_entry lost the ability to delete one entry of a multivar configuration. The moment you had more than one fetch or push ref spec for a remote you will not be able to save that remote anymore. The changes in network::remote::remotes::save show that problem. I needed to create a new git_config_delete_multivar because I was not able to remove one or several entries of a multivar config with the current API. Several tries modifying how git_config_set_multivar(..., NULL) behaved were not successful. git_config_delete_multivar is very similar to git_config_set_multivar, and delegates into config_delete_multivar of config_file. This function search for the cvar_t that will be deleted, storing them in a temporal array, and rebuilding the linked list. After calling config_write to delete the entries, the cvar_t stored in the temporal array are freed. There is a little fix in config_write, it avoids an infinite loop when using a regular expression (case for the multivars). This error was found by the test network::remote::remotes::tagopt.

a6154f21	2013-10-30T15:00:05	indexer: remove the stream infix It was there to keep it apart from the one which read in from a file on disk. This other indexer does not exist anymore, so there is no need for anything other than git_indexer to refer to it. While here, rename _add() function to _append() and _finalize() to _commit(). The former change is cosmetic, while the latter avoids talking about "finalizing", which OO languages use to mean something completely different.

ab46b1d8	2013-10-23T15:08:18	indexer: include the delta stats The user is unable to derive the number of deltas in the pack, as that would require them to capture the stats exactly in the moment between download and final processing, which is abstracted away in the fetch. Capture these numbers for the user and expose them in the progress struct. The clone and fetch examples now also present this information to the user.
70a8c78f	2013-10-23T12:08:54	Rename the ssh credentials The names from libssh2 are somewhat obtuse for us. We can simplify the usual key/passphrase credential's name, as well as make clearer what the custom signature function is.

3b5f7954	2013-10-21T13:42:42	Create git_diff_line and extend git_diff_hunk Instead of having functions with so very many parameters to pass hunk and line data, this takes the existing git_diff_hunk struct and extends it with more hunk data, plus adds a git_diff_line. Those structs are used to pass back hunk and line data instead of the old APIs that took tons of parameters. Some work that was previously only being done for git_diff_patch creation (scanning the diff content for exact line counts) is now done for all callbacks, but the performance difference should not be noticable.

92dac975	2013-10-08T16:35:57	Make reference lookups apply precomposeunicode Before these changes, looking up a reference would return the same precomposed or decomposed form of the reference name that was used to look it up, so on MacOS which ignores the difference between the two, a single reference could be looked up either way and git_reference_name would return the form of the name that was used to look it up! This change makes lookup always return the precomposed name if core.precomposeunicode is set regardless of which version was used to look it up. The reference iterator was already returning the precomposed form from earlier work. This also updates the CMakeLists.txt rules for enabling iconv usage because the clar tests for this code were actually not being activated properly with the old version. Finally, this moves git_repository_reset_filesystem from include/ git2/repository.h to include/git2/sys/repository.h since it is not really a function that normal library users should have to think about very often.
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.
13f670a5	2013-04-15T09:07:57	tree: allow retrieval of raw attributes When a tool needs to recreate the tree object (for example an interface to another VCS), it needs to use the raw attributes, forgoing any normalization.
5173ea92	2013-10-04T16:32:16	Add git_repository_reset_filesystem and fix tests When a repository is transferred from one file system to another, many of the config settings that represent the properties of the file system may be wrong. This adds a new public API that will refresh the config settings of the repository to account for the change of file system. This doesn't do a full "reinitialize" and operates on a existing git_repository object refreshing the config when done. This commit then makes use of the new API in clar as each test repository is set up. This commit also has a number of other clar test fixes where we were making assumptions about the type of filesystem, either based on outdated config data or based on the OS instead of the FS.

Test cancel from indexer progress callback This adds tests that try canceling an indexer operation from within the progress callback. After writing the tests, I wanted to run this under valgrind and had a number of errors in that situation because mmap wasn't working. I added a CMake option to force emulation of mmap and consolidated the Amiga-specific code into that new place (so we don't actually need separate Amiga code now, just have to turn on -DNO_MMAP). Additionally, I made the indexer code propagate error codes more reliably than it used to.

Update git_blob_create_fromchunks callback behavr The callback to supply data chunks could return a negative value to stop creation of the blob, but we were neither using GIT_EUSER nor propagating the return value.

Update docs for new callback return value behavior

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.

Add config read fns with controlled error behavior This adds `git_config__lookup_entry` which will look up a key in a config and return either the entry or NULL if the key was not present. Optionally, it can either suppress all errors or can return them (although not finding the key is not an error for this function). Unlike other accessors, this does not normalize the config key string, so it must only be used when the key is known to be in normalized form (i.e. all lower-case before the first dot and after the last dot, with no invalid characters). This also adds three high-level helper functions to look up config values with no errors and a fallback value. The three functions are for string, bool, and int values, and will resort to the fallback value for any error that arises. They are: * `git_config__get_string_force` * `git_config__get_bool_force` * `git_config__get_int_force` None of them normalize the config `key` either, so they can only be used for internal cases where the key is known to be in normal format.

Add GIT_DIFF_FIND_DELETE_UNMODIFIED flag When doing copy detection, it is often necessary to include UNMODIFIED records in the git_diff so they are available as source records for GIT_DIFF_FIND_COPIES_FROM_UNMODIFIED. Yet in the final diff, often you will not want to have these UNMODIFIED records. This adds a flag which marks these UNMODIFIED records for deletion from the diff list so they will be removed after the rename detect phase is over.

reflog: remove git_reflog_append_to() This was a convenience method for the refs front-end to do the reflog writing. This is now done in the backend and it has no more reason for being.

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.

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.

Add git_diff_options_init helper Sometimes the static initializer for git_diff_options cannot be used and since setting them to all zeroes doesn't actually work quite right, this adds a new helper for that situation.

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.

3793fa9b

2013-10-31T01:08:50

Fix saving remotes with several fetch/push ref specs. At some moment git_config_delete_entry lost the ability to delete one entry of a multivar configuration. The moment you had more than one fetch or push ref spec for a remote you will not be able to save that remote anymore. The changes in network::remote::remotes::save show that problem. I needed to create a new git_config_delete_multivar because I was not able to remove one or several entries of a multivar config with the current API. Several tries modifying how git_config_set_multivar(..., NULL) behaved were not successful. git_config_delete_multivar is very similar to git_config_set_multivar, and delegates into config_delete_multivar of config_file. This function search for the cvar_t that will be deleted, storing them in a temporal array, and rebuilding the linked list. After calling config_write to delete the entries, the cvar_t stored in the temporal array are freed. There is a little fix in config_write, it avoids an infinite loop when using a regular expression (case for the multivars). This error was found by the test network::remote::remotes::tagopt.

This other indexer does not exist anymore, so there is no need for anything other than git_indexer to refer to it. While here, rename _add() function to _append() and _finalize() to _commit(). The former change is cosmetic, while the latter avoids talking about "finalizing", which OO languages use to mean something completely different.

Create git_diff_line and extend git_diff_hunk Instead of having functions with so very many parameters to pass hunk and line data, this takes the existing git_diff_hunk struct and extends it with more hunk data, plus adds a git_diff_line. Those structs are used to pass back hunk and line data instead of the old APIs that took tons of parameters. Some work that was previously only being done for git_diff_patch creation (scanning the diff content for exact line counts) is now done for all callbacks, but the performance difference should not be noticable.

Make reference lookups apply precomposeunicode Before these changes, looking up a reference would return the same precomposed or decomposed form of the reference name that was used to look it up, so on MacOS which ignores the difference between the two, a single reference could be looked up either way and git_reference_name would return the form of the name that was used to look it up! This change makes lookup always return the precomposed name if core.precomposeunicode is set regardless of which version was used to look it up. The reference iterator was already returning the precomposed form from earlier work. This also updates the CMakeLists.txt rules for enabling iconv usage because the clar tests for this code were actually not being activated properly with the old version. Finally, this moves git_repository_reset_filesystem from include/ git2/repository.h to include/git2/sys/repository.h since it is not really a function that normal library users should have to think about very often.

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.

tree: allow retrieval of raw attributes When a tool needs to recreate the tree object (for example an interface to another VCS), it needs to use the raw attributes, forgoing any normalization.

Add git_repository_reset_filesystem and fix tests When a repository is transferred from one file system to another, many of the config settings that represent the properties of the file system may be wrong. This adds a new public API that will refresh the config settings of the repository to account for the change of file system. This doesn't do a full "reinitialize" and operates on a existing git_repository object refreshing the config when done. This commit then makes use of the new API in clar as each test repository is set up. This commit also has a number of other clar test fixes where we were making assumptions about the type of filesystem, either based on outdated config data or based on the OS instead of the FS.

indexer: fix thin packs When given an ODB from which to read objects, the indexer will attempt to inject the missing bases at the end of the pack and update the header and trailer to reflect the new contents.
