* Teach fast-import to recursively copy files/directoriesShawn O. Pearce2007-07-15
| | | | | | | | | | | | | | | | | | | | | | Some source material (e.g. Subversion dump files) perform directory renames by telling us the directory was copied, then deleted in the same revision. This makes it difficult for a frontend to convert such data formats to a fast-import stream, as all the frontend has on hand is "Copy a/ to b/; Delete a/" with no details about what files are in a/, unless the frontend also kept track of all files. The new 'C' subcommand within a commit allows the frontend to make a recursive copy of one path to another path within the branch, without needing to keep track of the individual file paths. The metadata copy is performed in memory efficiently, but is implemented as a copy-immediately operation, rather than copy-on-write. With this new 'C' subcommand frontends could obviously implement an 'R' (rename) on their own as a combination of 'C' and 'D' (delete), but since we have already offered up 'R' in the past and it is a trivial thing to keep implemented I'm not going to deprecate it.

* Support wholesale directory renames in fast-importShawn O. Pearce2007-07-09
| | | | | | | | | | | | | | | | | Some source material (e.g. Subversion dump files) perform directory renames without telling us exactly which files in that subdirectory were moved. This makes it hard for a frontend to convert such data formats to a fast-import stream, as all the frontend has on hand is "Rename a/ to b/" with no details about what files are in a/, unless the frontend also kept track of all files. The new 'R' subcommand within a commit allows the frontend to rename either a file or an entire subdirectory, without needing to know the object's SHA-1 or the specific files contained within it. The rename is performed as efficiently as possible internally, making it cheaper than a 'D'/'M' pair for a file rename. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>

| * Fix possible coredump with fast-import --import-marksShawn O. Pearce2007-05-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When e8438420bb7d368bec3647b90c557b9931582267 allowed us to reload the marks table on subsequent runs of fast-import we really broke things, as we set pack_id to MAX_PACK_ID for any objects we imported into the marks table. Creating a branch from that mark should fail as we attempt to read the object through a non-existant packed_git pointer. Instead we have to use the normal Git object system to locate the older commit, as we ourselves do not have a reference to the packed_git it resides in. This bug only occurred because t9300 was not complete enough. When we added the --import-marks feature we didn't actually test its implementation enough to verify the function worked as intended. I have corrected that, and included the changes as part of this fix. Prior versions of fast-import fail the new test(s); this commit allows them to pass. Credit for this bug find goes to Simon Hausmann <simon@lst.de> as he recently identified a similiar bug in the tree lazy-loading path. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>

* | Don't repack existing objects in fast-importShawn O. Pearce2007-04-20
|/ | | | | | | | | | | | | | | | | | | | | Some users of fast-import have been trying to use it to rewrite commits and trees, an activity where the all of the relevant blobs are already available from the existing packfiles. In such a case we don't want to repack a blob, even if the frontend application has supplied us the raw data rather than a mark or a SHA-1 name. I'm intentionally only checking the packfiles that existed when fast-import started and am always ignoring all loose object files. We ignore loose objects because fast-import tends to operate on a very large number of objects in a very short timespan, and it is usually creating new objects, not reusing existing ones. In such a situtation the majority of the objects will not be found in the existing packfiles, nor will they be loose object files. If the frontend application really wants us to look at loose object files, then they can just repack the repository before running fast-import. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building up a tree for a commit, fast-import dynamically allocates memory for the tree entries. When more space is needed, the allocated memory is increased by a constant amount. For very large trees, this means re-allocating and memcpy()ing the memory O(n) times. To compound this problem, releasing the previous tree resource does not free the memory; it is kept in a pool for future trees. This means that each of the O(n) allocations will consume increasing amounts of memory, giving O(n^2) memory consumption. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Shawn O.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we allow fast-import frontends to reload a mark file from a prior session we want to let them use the same file as they exported the marks to. This makes it very simple for the frontend to save state across incremental imports. But we don't want to lose the old marks table if anything goes wrong while writing our current marks table. So instead of truncating and overwriting the path specified to --export-marks we use the standard lockfile code to write the current marks out to a temporary file, then rename it over the old marks table.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I'm about to teach fast-import how to reload the marks file created by a prior session. The general approach that I want to use is to immediately parse the marks file when the specific argument is found in argv, thereby allowing the caller to supply multiple marks files, as the mark space can be sparsely populated. To make that work out we need to allocate our object tables before we parse the command line options. Since none of these tables depend on the command line options, we can easily relocate them.

By using off_t, the POSIX type that is declared to mean an offset within a file, we support whatever maximum file size the underlying operating system will handle.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We shouldn't attempt to assign constant strings into char*, as the string is not writable at runtime. Likewise we should always be treating unsigned values as unsigned values, not as signed values. Most of these are very straightforward. The only exception is the (unnecessary) xstrdup/free in builtin-branch.c for the detached head case. Since this is a user-level interactive type program and that particular code path is executed no more than once, I feel that the extra xstrdup call is well worth the easy elimination of this warning.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Johannes Sixt noticed during one of his own imports that fast-import did not fail if a non-existant commit is referenced by SHA-1 value as an argument to the 'merge' command. This allowed the user to unknowingly create commits that would fail in fsck, as the commit contents would not be completely reachable. A side effect of this bug was that a frontend process could mark any SHA-1 object (blob, tree, tag) as a parent of a merge commit. This should also fail in fsck, as the commit is not a valid commit. We now use the same rule as the 'from' command. If a commit is referenced in the 'merge' command by hex formatted SHA-1 then the SHA-1 must be a commit or a tag that can be peeled back to a commit, the commit must already exist, and must be readable by the core Git infrastructure code. This requirement means that the commit must have existed prior to fast-import starting, or the commit must have been flushed out by a prior 'checkpoint' command. Signed-off-by: Shawn O.

| * fast-import: Avoid infinite loop after resetShawn O. Pearce2007-03-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Johannes Sixt noticed that a 'reset' command applied to a branch that is already active in the branch LRU cache can cause fast-import to relink the same branch into the LRU cache twice. This will cause the LRU cache to contain a cycle, making unload_one_branch run in an infinite loop as it tries to select the oldest branch for eviction. I have trivially fixed the problem by adding an active bit to each branch object; this bit indicates if the branch is already in the LRU and allows us to avoid trying to add it a second time. Converting the pack_id field into a bitfield makes this change take up no additional memory. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>

* fast-import: Support reusing 'from' and brown paper bag fix reset.Shawn O. Pearce2007-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was suggested on the mailing list that being able to use `from` in any commit to reset the current branch is useful in some types of importers, such as a darcs importer. We originally did not permit resetting an existing branch with a new `from` command during a `commit` command, but this restriction was only to help debug the hacked up cvs2svn that Jon Smirl was developing in parallel with git-fast-import. It is probably more of a problem to disallow it than to allow it. So now we permit a `from` during any `commit`. While making the changes required to permit multiple `from` commands on the same branch, I discovered we no longer needed the last_commit field to be set to 0 during a reset, so that was removed. (Reset was originally setting the field to 0 to signal cmd_from() that it was OK to execute on the branch.) While poking around in this section of fast-import I also realized the `reset` command was not working as intended if the corresponding `from` command was omitted (as allowed by the BNF grammar and the code). If `from` was omitted we cleared out the tree but we left the tree SHA-1 and parent commit SHA-1 intact. This is not what the user intended in this case. Instead they would be trying to reset the branch to have no parent and to have no tree, making the branch look new-born during the next commit. We now clear these SHA-1 values during `reset`, ensuring the branch looks new-born if `from` does not get supplied. New test cases for these were also added. Signed-off-by: Shawn O.

* Teach fast-import how to clear the internal branch content.Shawn O. Pearce2007-02-07
| | | | | | | | | | | | | | | | | | | Some frontends may not be able to (easily) keep track of which files are included in the branch, and which aren't. Performing this tracking can be tedious and error prone for the frontend to do, especially if its foreign data source cannot supply the changed path list on a per-commit basis. fast-import now allows a frontend to request that a branch's tree be wiped clean (reset to the empty tree) at the start of a commit, allowing the frontend to feed in all paths which belong on the branch. This is ideal for a tar-file importer frontend, for example, as the frontend just needs to reformat the tar data stream into a gfi data stream, which may be something a few Perl regexps can take care of. :) Signed-off-by: Shawn O.

| | | | | | | | | | | | | | | | | If fast-import is being used to update an existing branch of a repository, the user may not want to lose commits if another process updates the same ref at the same time. For example, the user might be using fast-import to make just one or two commits against a live branch. We now perform a fast-forward check during the ref updating process. If updating a branch would cause commits in that branch to be lost, we skip over it and display the new SHA1 to standard error. This new default behavior can be overridden with `--force`, like git-push and git-fetch. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
* Support RFC 2822 date parsing in fast-import.Shawn O. Pearce2007-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Since some frontends may be working with source material where the dates are only readily available as RFC 2822 strings, it is more friendly if fast-import exposes Git's parse_date() function to handle the conversion. This way the frontend doesn't need to perform the parsing itself. The new --date-format option to fast-import can be used by a frontend to select which format it will supply date strings in. The default is the standard `raw` Git format, which fast-import has always supported. Format rfc2822 can be used to activate the parse_date() function instead. Because fast-import could also be useful for creating new, current commits, the format `now` is also supported to generate the current system timestamp. The implementation of `now` is a trivial call to datestamp(), but is actually a whole whopping 3 lines so that fast-import can verify the frontend really meant `now`. As part of this change I have added validation of the `raw` date format. Prior to this change fast-import would accept anything in a `committer` command, even if it was seriously malformed. Now fast-import requires the '> ' near the end of the string and verifies the timestamp is formatted properly. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
* Remove unnecessary null pointer checks in fast-import.Shawn O. Pearce2007-02-06
| | | | | | | There is no need to check for a NULL pointer before invoking free(), the runtime library automatically performs this check anyway and does nothing if a NULL pointer is supplied. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
* Correct minor style issue in fast-import.Shawn O. Pearce2007-02-06
| | | | | | | | | Junio noticed that I was using a different style in fast-import for returned pointers than the rest of Git. Before merging this code into the main git.git tree I'd like to make it consistent, as this style variation was not intentional. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
