* vcs-svn: move remaining repo_tree functions to fast_export.hjn/vcs-svn-cleanupJonathan Nieder2017-08-231-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | These used to be for manipulating the in-memory repo_tree structure, but nowadays they are convenience wrappers to handle a few git-vs-svn mismatches: 1. Git does not track empty directories but Subversion does. When looking up a path in git that Subversion thinks exists and finding nothing, we can safely assume that the path represents a directory. This is needed when a later Subversion revision modifies that directory. 2. Subversion allows deleting a file by copying. In Git fast-import we have to handle that more explicitly as a deletion. These are details of the tool's interaction with git fast-import. Move them to fast_export.c, where other such details are handled. This way the function names do not start with a repo_ prefix that would clash with the repository object introduced in v2.14.0-rc0~38^2~16 (repository: introduce the repository object, 2017-06-22) or an svn_ prefix that would clash with libsvn (in case someone wants to link this code with libsvn some day).

* vcs-svn: rename repo functions to "svn_repo"bc/vcs-svn-cleanupbrian m. carlson2017-08-201-3/+3
| | | | | | | | | | There were several functions in the Subversion code that started with "repo_". This namespace is also used by the Git struct repository code. Rename these functions to start with "svn_repo" to avoid any future conflicts. Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that there is no internal representation of the repo, it is not necessary to tokenise paths. Use strbuf instead and bypass string_pool. This means svn-fe can handle arbitrarily long paths (as long as a strbuf can fit them), with arbitrarily many path components. While at it, since we now treat paths in their entirety, only quote when necessary. Signed-off-by: David Barr <david.barr@cordelta.com> Signed-off-by: Jonathan Nieder <jrnieder@gmail.com>

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently there are two functions to retrieve the mode and content at a path: const char *repo_read_path(const uint32_t *path); uint32_t repo_read_mode(const uint32_t *path) Replace them with a single function with two return values. This means we can use one round-trip to get the same information from fast-import that previously took two.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rely on fast-import for information about previous revs. This requires always setting up backward flow of information, even for v2 dumps. On the plus side, it simplifies the code by quite a bit and opens the door to further simplifications.

* | | vcs-svn: handle log message with embedded NULJonathan Nieder2011-03-261-2/+2
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pass the log message by strbuf instead of as a C-style string and use fwrite instead of printf to write it to fast-import so embedded '\0' bytes can be preserved. Currently "git log" doesn't show the embedded NULs but "git cat-file commit" can. While at it, stop including system headers from repo_tree.h. git source files need to include git-compat-util.h (or cache.h or builtin.h) sooner to ensure the appropriate feature test macros are defined.

* | vcs-svn: use strbuf for author, UUID, and URLDavid Barr2011-03-221-2/+3
|/ | | | | | | | | | | | | | | | Use strbufs and strings instead of interned strings for values of rev, dump, and node fields that happen to be strings. After this change, the only remaining string_pool use is for paths in the repo_tree API and internals. Functional change: treat an empty author, UUID, or URL as none at all. So for example, in repos where the first revision has an empty svn:author property, the first rev will be treated as by "nobody" rather than by a person with empty name and email address created by prepending an @ sign to the repository UUID.

* vcs-svn: simplify repo_modify_path and repo_copyJonathan Nieder2011-03-071-2/+2
| | | | | | | | | | | | | | | Restrict the repo_tree API to functions that are actually needed. - decouple reading the mode and content of dirents from other operations. - remove repo_modify_path. It is only used to read the mode from dirents. - remove the ability to use repo_read_mode on a missing path. The existing code only errors out in that case, anyway.

* vcs-svn: introduce repo_read_path to check the content at a pathJonathan Nieder2011-03-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | The repo_tree structure remembers, for each path in each revision, a mode (regular file, executable, symlink, or directory) and content (blob mark or directory structure). Maintaining a second copy of all this information when it's already in the target repository is wasteful, it does not persist between svn-fe invocations, and most importantly, there is no convenient way to transfer it from one machine to another. So it would be nice to get rid of it. As a first step, let's change the repo_tree API to match fast-import's read commands more closely. Currently to read the mode for a path, one uses repo_modify_path(path, new_mode, new_content); which changes the mode and content as a side effect. There is no function to read the content at a path; add one.

* vcs-svn: Combine repo_replace and repo_modify functionsJonathan Nieder2010-11-241-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | There are two functions to change the staged content for a path in the svn importer's active commit: repo_replace, which changes the text and returns the mode, and repo_modify, which changes the text and mode and returns nothing. Worse, there are more subtle differences: - A mark of 0 passed to repo_modify means "use the existing content". repo_replace uses it as mark :0 and produces a corrupt stream. - When passed a path that is not part of the active commit, repo_replace returns without doing anything. repo_modify transparently adds a new directory entry. Get rid of both and introduce a new function with the best features of both: repo_modify_path modifies the mode, content, or both for a path, depending on which arguments are zero. If no such dirent already exists, it does nothing and reports the error by returning 0. Otherwise, the return value is the resulting mode.

* Infrastructure to write revisions in fast-export formatDavid Barr2010-08-141-0/+26
repo_tree maintains the exporter's state and provides a facility to to call fast_export, which writes objects to stdout suitable for consumption by fast-import. The exported functions roughly correspond to Subversion FS operations. . repo_add, repo_modify, repo_copy, repo_replace, and repo_delete update the current commit, based roughly on the corresponding Subversion FS operation. . repo_commit calls out to fast_export to write the current commit to the fast-import stream in stdout. . repo_diff is used by the fast_export module to write the changes for a commit. . repo_reset erases the exporter's state, so valgrind can be happy.
