* config: remove the refresh function and backend fieldcmn/config-refresh-removeCarlos Martín Nieto2014-10-231-1/+0
| | | | | | 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.

| * Introduce reference transactionsCarlos Martín Nieto2014-09-301-0/+13
| | | | | | | | | | | | | | | | | | A transaction allows you to lock multiple references and set up changes for them before applying the changes all at once (or as close as the backend supports). This can be used for replication purposes, or for making sure some operations run when the reference is locked and thus cannot be changed.

|\ | | | | Provide a callback for certificate validation
| * net: remove support for outright ignoring certificatesCarlos Martín Nieto2014-09-161-3/+0
| | | | | | | | | | | | | | | | | | | | This option make it easy to ignore anything about the server we're connecting to, which is bad security practice. This was necessary as we didn't use to expose detailed information about the certificate, but now that we do, we should get rid of this. If the user wants to ignore everything, they can still provide a callback which ignores all the information passed.
| * Provide a callback for certificate validationCarlos Martín Nieto2014-09-161-0/+1
| | | | | | | | | | | | | | | | | | If the certificate validation fails (or always in the case of ssh), let the user decide whether to allow the connection. The data structure passed to the user is the native certificate information from the underlying implementation, namely OpenSSL or WinHTTP.
* | Fix attribute lookup in index for bare reposrb/attr-with-bareRussell Belfer2014-09-151-0/+13
|/ | | | | | | | | | | | | | | | When using a bare repo with an index, libgit2 attempts to read files from the index. It caches those files based on the path to the file, specifically the path to the directory that contains the file. If there is no working directory, we use `git_path_dirname_r` to get the path to the containing directory. However, for the `.gitattributes` file in the root of the repository, this ends up normalizing the containing path to `"."` instead of the empty string and the lookup the `.gitattributes` data fails. This adds a test of attribute lookups on bare repos and also fixes the problem by simply rewriting `"."` to be `""`.
* Custom transport: minor cleanupsEdward Thomson2014-08-141-0/+354
| | | | | | | | | | | | * Move the transport registration mechanisms into a new header under 'sys/' because this is advanced stuff. * Remove the 'priority' argument from the registration as it adds unnecessary complexity. (Since transports cannot decline to operate, only the highest priority transport is ever executed.) Users who require per-priority transports can implement that in their custom transport themselves. * Simplify registration further by taking a scheme (eg "http") instead of a prefix (eg "http://").

|\ | | | | Configuration snapshotting
| * config: refresh before reading a valueCarlos Martín Nieto2014-04-181-1/+1
| | | | | | | | | | | | | | | | | | | | With the isolation of complex reads, we can now try to refresh the on-disk file before reading a value from it. This changes the semantics a bit, as before we could be sure that a string we got from the configuration was valid until we wrote or refreshed. This is no longer the case, as a read can also invalidate the pointer.
| * config: implement config snapshottingCarlos Martín Nieto2014-04-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | In order to have consistent views of the config files for remotes, submodules et al. and a configuration that represents what is currently stored on-disk, we need a way to provide a view of the configuration that does not change. The goal here is to provide the snapshotting part by creating a read-only copy of the state of the configuration at a particular point in time, which does not change when a repository's main config changes.

* | Add filter options and ALLOW_UNSAFERussell Belfer2014-05-061-2/+10
| | | | | | | | | | | | | | | | | | 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.

* Add git_commit_amend APIRussell Belfer2014-02-071-3/+37
| | | | | | | | | This adds an API to amend an existing commit, basically a shorthand for creating a new commit filling in missing parameters from the values of an existing commit. As part of this, I also added a new "sys" API to create a commit using a callback to get the parents. This allowed me to rewrite all the other commit creation APIs so that temporary allocations are no longer needed.

|\ | | | | Reference operations with log
| * refs: expose has_log() on the backendCarlos Martín Nieto2013-12-091-0/+5
| | | | | | | | | | | | The frontend used to look at the file directly, but that's obviously not the right thing to do. Expose it on the backend and use that function instead.
| * refs: expose a way to ensure a ref has a logCarlos Martín Nieto2013-12-091-0/+6
| | | | | | | | | | | | 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.
| * reflog: integrate into the ref writingCarlos Martín Nieto2013-11-231-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | 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.
| * refdb: add a `message` parameter for appending to the logCarlos Martín Nieto2013-11-231-2/+4
| | | | | | | | This is as yet unused.
* | Cleanups, renames, and leak fixesRussell Belfer2013-12-121-0/+1
|/ | | | | | | | | 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.
* Fix saving remotes with several fetch/push ref specs.Daniel Rodríguez Troitiño2013-11-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | 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.

| * | reflog: move the reflog implementation into refdb_fsCarlos Martín Nieto2013-10-022-0/+53
| |/ | | | | | | | | | | | | | | | | | | 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.
* | Rename new fn to git_repository_reinit_filesystemRussell Belfer2013-10-081-2/+2

* | Make reference lookups apply precomposeunicodeRussell Belfer2013-10-081-1/+19
|/ | | | | | | | | | | | | | | | | | | | | 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.

* Bug fixes and cleanupsRussell Belfer2013-09-171-33/+68
| | | | | | | | | | | | | This contains a few bug fixes and some header and API cleanups. The main API change is that filters should now use GIT_PASSTHROUGH to indicate that they wish to skip processing a file instead of GIT_ENOTFOUND. The bug fixes include a possible out-of-range buffer access in the ident filter, a filter ordering problem I introduced into the custom filter tests on Windows, and a filter buf NUL termination issue that was coming up on Linux.
* More filtering tests including orderRussell Belfer2013-09-171-0/+14
| | | | | | | | | | | This adds more tests of filters, including the ident filter when mixed with custom filters. I was able to combine with the reverse filter and demonstrate that the order of filter application with the default priority constants matches the order of core Git. Also, this fixes two issues in the ident filter: preventing ident expansion on binary files and avoiding a NULL dereference when dollar sign characters are found without Id.
* Port tests from PR 1683Russell Belfer2013-09-171-0/+13
| | | | | | This ports over some of the tests from https://github.com/libgit2/libgit2/pull/1683 by @yorah and @ethomson
* Merge git_buf and git_bufferRussell Belfer2013-09-171-9/+9
| | | | | | | | | | | 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 filterRussell Belfer2013-09-171-3/+8
| | | | | | | 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.
* Add functions to manipulate filter listsRussell Belfer2013-09-171-0/+37
| | | | | | | | Extend the git2/sys/filter API with functions to look up a filter and add it manually to a filter list. This requires some trickery because the regular attribute lookups and checks are bypassed when this happens, but in the right hands, it will allow a user to have granular control over applying filters.
* Hook up filter initialize callbackRussell Belfer2013-09-171-0/+2
| | | | I knew I forgot something
* Extend public filter api with filter listsRussell Belfer2013-09-171-10/+10
| | | | | | | | | | | 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.
