2020-05-31fast-import: add new --date-format=raw-permissive formatLibravatar Elijah Newren1-1/+8
There are multiple repositories in the wild with random, invalid timezones. Most notably is a commit from rails.git with a timezone of "+051800"[1]. A few searches will find other repos with that same invalid timezone as well. Further, Peff reports that GitHub relaxed their fsck checks in August 2011 to accept any timezone value[2], and there have been multiple reports to filter-repo about fast-import crashing while trying to import their existing repositories since they had timezone values such as "-7349423" and "-43455309"[3]. The existing check on timezone values inside fast-import may prove useful for people who are crafting fast-import input by hand or with a new script. For them, the check may help them avoid accidentally recording invalid dates. (Note that this check is rather simplistic and there are still several forms of invalid dates that fast-import does not check for: dates in the future, timezone values with minutes that are not divisible by 15, and timezone values with minutes that are 60 or greater.) While this simple check may have some value for those users, other users or tools will want to import existing repositories as-is. Provide a --date-format=raw-permissive format that will not error out on these otherwise invalid timezones so that such existing repositories can be imported.

2020-02-28fast-import: add options for rewriting submodulesLibravatar brian m. carlson1-0/+20
When converting a repository using submodules from one hash algorithm to another, it is necessary to rewrite the submodules from the old algorithm to the new algorithm, since only references to submodules, not their contents, are written to the fast-export stream. Without rewriting the submodules, fast-import fails with an "Invalid dataref" error when encountering a submodule in another algorithm. Add a pair of options, --rewrite-submodules-from and --rewrite-submodules-to, that take a list of marks produced by fast-export and fast-import, respectively, when processing the submodule. Use these marks to map the submodule commits from the old algorithm to the new algorithm. We read marks into two corresponding struct mark_set objects and then perform a mapping from the old to the new using a hash table. This lets us reuse the same mark parsing code that is used elsewhere and allows us to efficiently read and match marks based on their ID, since mark files need not be sorted. Note that because we're using a khash table for the object IDs, and this table copies values of struct object_id instead of taking references to them, it's necessary to zero the struct object_id values that we use to insert and look up in the table. Otherwise, we would end up with SHA-1 values that don't match because of whatever stack garbage might be left in the unused area.

2019-12-04fast-import: disallow "feature import-marks" by defaultLibravatar Jeff King1-1/+2
As with export-marks in the previous commit, import-marks can access the filesystem. This is significantly less dangerous than export-marks because it only involves reading from arbitrary paths, rather than writing them. However, it could still be surprising and have security implications (e.g., exfiltrating data from a service that accepts fast-import streams). Let's lump it (and its "if-exists" counterpart) in with export-marks, and enable the in-stream version only if --allow-unsafe-features is set. Signed-off-by: Jeff King <peff@peff.net>
2019-12-04fast-import: disallow "feature export-marks" by defaultLibravatar Jeff King1-0/+14
The fast-import stream command "feature export-marks=<path>" lets the stream write marks to an arbitrary path. This may be surprising if you are running fast-import against an untrusted input (which otherwise cannot do anything except update Git objects and refs). Let's disallow the use of this feature by default, and provide a command-line option to re-enable it (you can always just use the command-line --export-marks as well, but the in-stream version provides an easy way for exporters to control the process). This is a backwards-incompatible change, since the default is flipping to the new, safer behavior. However, since the main users of the in-stream versions would be import/export-based remote helpers, and since we trust remote helpers already (which are already running arbitrary code), we'll pass the new option by default when reading a remote helper's stream. This should minimize the impact. Note that the implementation isn't totally simple, as we have to work around the fact that fast-import doesn't parse its command-line options until after it has read any "feature" lines from the stream. This is how it lets command-line options override in-stream. But in our case, it's important to parse the new --allow-unsafe-features first. There are three options for resolving this: 1. Do a separate "early" pass over the options. This is easy for us to do because there are no command-line options that allow the "unstuck" form (so there's no chance of us mistaking an argument for an option), though it does introduce a risk of incorrect parsing later (e.g,. if we convert to parse-options). 2. Move the option parsing phase back to the start of the program, but teach the stream-reading code never to override an existing value. This is tricky, because stream "feature" lines override each other (meaning we'd have to start tracking the source for every option). 3. Accept that we might parse a "feature export-marks" line that is forbidden, as long we don't _act_ on it until after we've parsed the command line options. This would, in fact, work with the current code, but only because the previous patch fixed the export-marks parser to avoid touching the filesystem. So while it works, it does carry risk of somebody getting it wrong in the future in a rather subtle and unsafe way. I've gone with option (1) here as simple, safe, and unlikely to cause regressions. This fixes CVE-2019-1348. Signed-off-by: Jeff King <peff@peff.net>
2019-10-04fast-import: add support for new 'alias' commandLibravatar Elijah Newren1-0/+22
fast-export and fast-import have nice --import-marks flags which allow for incremental migrations. However, if there is a mark in fast-export's file of marks without a corresponding mark in the one for fast-import, then we run the risk that fast-export tries to send new objects relative to the mark it knows which fast-import does not, causing fast-import to fail. This arises in practice when there is a filter of some sort running between the fast-export and fast-import processes which prunes some commits programmatically. Provide such a filter with the ability to alias pruned commits to their most recent non-pruned ancestor.

2019-10-04fast-import: allow tags to be identified by mark labelsLibravatar Elijah Newren1-0/+1
Mark identifiers are used in fast-export and fast-import to provide a label to refer to earlier content. Blobs are given labels because they need to be referenced in the commits where they first appear with a given filename, and commits are given labels because they can be the parents of other commits. Tags were never given labels, probably because they were viewed as unnecessary, but that presents two problems: 1. It leaves us without a way of referring to previous tags if we want to create a tag of a tag (or higher nestings). 2. It leaves us with no way of recording that a tag has already been imported when using --export-marks and --import-marks. Fix these problems by allowing an optional mark label for tags.

Since git supports commit messages with an encoding other than UTF-8, allow fast-import to import such commits. This may be useful for folks who do not want to reencode commit messages from an external system, and may also be useful to achieve reversible history rewrites (e.g. sha1sum <-> sha256sum transitions or subtree work) with git repositories that have used specialized encodings in their commit history.

2019-04-01fast-import: fix erroneous handling of get-mark with empty orphan commitsLibravatar Elijah Newren1-4/+0
When get-mark was introduced in commit 28c7b1f7b7b7 ("fast-import: add a get-mark command", 2015-07-01), it followed the precedent of the cat-blob command to be allowed on any line other than in the middle of a data directive; see commit 777f80d7429b ("fast-import: Allow cat-blob requests at arbitrary points in stream", 2010-11-28). It was useful to allow cat-blob directives in the middle of a commit to get more data that would be used in writing the current commit object. get-mark is not similarly useful since fast-import can already use either object id or mark. Further, trying to allow this command anywhere caused parsing bugs. Fix the parsing problems by only allowing get-mark commands to appear when other commands have completed.

2019-04-01fast-import: only allow cat-blob requests where it makes senseLibravatar Elijah Newren1-3/+4
In commit 777f80d7429b ("fast-import: Allow cat-blob requests at arbitrary points in stream", 2010-11-28), fast-import started allowing cat-blob commands to appear on the start of any line except in the middle of a "data" command. It could be in the middle of various directives that were part of a tag command, or in the middle of checkpoints or progresses (each of which allow an optional second empty newline), or even immediately after the mark command of a blob before the data directive appeared (raising the question of what if it used the mark for the blob that just barely appeared in the stream that we do not yet have the data for). None of these locations make any sense as places to put cat-blob requests. The purpose of this change as stated in that commit message was to [save] frontends from having to loop over everything they want to commit in the next commit and cat-ing the necessary objects in advance. However, that can be achieved by simply allowing cat-blob requests to appear whenever a filemodify directive is allowed. Further, it avoids setting a bad precedent for other commands to follow (e.g. get-mark); a precedent which caused parsing problems in corner cases. Technically, inline filemodify directives add a slight wrinkle in that frontends might want to have cat-blob directives appear after the start of the filemodify and before the data directive contained within it. I think it would have been better to disallow such a case (it would be trivial to use cat-blob before the filemodify instead), but since there is evidence this was used, for backwards compatibility let's support that case too.

2018-11-17fast-export: add a --show-original-ids option to show original namesLibravatar Elijah Newren1-0/+16
Knowing the original names (hashes) of commits can sometimes enable post-filtering that would otherwise be difficult or impossible. In particular, the desire to rewrite commit messages which refer to other prior commits (on top of whatever other filtering is being done) is very difficult without knowing the original names of each commit. In addition, knowing the original names (hashes) of blobs can allow filtering by blob-id without requiring re-hashing the content of the blob, and is thus useful as a small optimization. Once we add original ids for both commits and blobs, we may as well add them for tags too for completeness. Perhaps someone will have a use for them. This commit teaches a new --show-original-ids option to fast-export which will make it add a 'original-oid <hash>' line to blob, commits, and tags. It also teaches fast-import to parse (and ignore) such lines. Signed-off-by: Elijah Newren <newren@gmail.com> Acked-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

With many incremental imports, small packs become highly inefficient due to the need to readdir scan and load many indices to locate even a single object. Frequent repacking and consolidation may be prohibitively expensive in terms of disk I/O, especially in large repositories where the initial packs were aggressively optimized and marked with .keep files. In those cases, users may be better served with loose objects and relying on "git gc --auto".

Also link to fast-import from the remote helper spec, as this is relevant for remote helpers using the fast-import format.

2013-11-12Correct word usage of "timezone" in "Documentation" directoryLibravatar Jason St. John1-5/+5
"timezone" is two words, not one (i.e. "time zone" is correct). Correct this in these files: -- date-formats.txt -- git-blame.txt -- git-cvsimport.txt -- git-fast-import.txt -- git-svn.txt -- gitweb.conf.txt -- rev-list-options.txt Signed-off-by: Jason St. John <jstjohn@purdue.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-09-17Merge branch 'rh/ishes-doc'Libravatar Junio C Hamano1-13/+13
We liberally use "committish" and "commit-ish" (and "treeish" and "tree-ish"); as these are non-words, let's unify these terms to their dashed form. More importantly, clarify the documentation on object peeling using these terms. * rh/ishes-doc: glossary: fix and clarify the definition of 'ref' revisions.txt: fix and clarify <rev>^{<type>} glossary: more precise definition of tree-ish (a.k.a. treeish) use 'commit-ish' instead of 'committish' use 'tree-ish' instead of 'treeish' glossary: define commit-ish (a.k.a. committish) glossary: mention 'treeish' as an alternative to 'tree-ish'
2013-09-04use 'commit-ish' instead of 'committish'Libravatar Richard Hansen1-13/+13
Replace 'committish' in documentation and comments with 'commit-ish' to match gitglossary(7) and to be consistent with 'tree-ish'. The only remaining instances of 'committish' are: * variable, function, and macro names * "(also committish)" in the definition of commit-ish in gitglossary[7] Signed-off-by: Richard Hansen <rhansen@bbn.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-08-25Documentation/fast-import: clarify summary for `feature` commandLibravatar Matthieu Moy1-2/+2
In most cases, "feature <foo>" does not just require that the feature exists, but also changes the behavior by enabling it. Cases where the feature is only requested like cat-blob, notes or ls are clearly documented below.

2013-01-09git-fast-import(1): reorganise optionsLibravatar John Keeping1-39/+47
The options in git-fast-import(1) are not currently arranged in a logical order, which has caused the '--done' options to be documented twice (commit 3266de10). Rearrange them into logical groups under subheadings.
