2010-08-11fast-import: export correctly marks larger than 2^20-1Libravatar Raja R Harinath1-0/+57
dump_marks_helper() has a bug when dumping marks larger than 2^20-1, i.e., when the sparse array has more than two levels. The bug was that the 'base' counter was being shifted by 20 bits at level 3, and then again by 10 bits at level 2, rather than a total shift of 20 bits in this argument to the recursive call: (base + k) << m->shift There are two ways to fix this correctly, the elegant: (base + k) << 10 and the one I chose due to edit distance: base + (k << m->shift) Signed-off-by: Raja R Harinath <harinath@hurrynot.org> Acked-by: Shawn O.

2010-07-05Teach fast-import to import subtrees named by tree idLibravatar Jonathan Nieder1-0/+54
To simulate the svn cp command, it would be very useful to be replace an arbitrary file in the current revision by an arbitrary directory from a previous one. Modify the filemodify command to allow that: M 040000 <tree id> pathname This would be most useful in combination with a facility to print the commit ids for new revisions as they are written.

If a blob is larger than the configured big-file-threshold, instead of reading it into a single buffer obtained from malloc, stream it onto the end of the current pack file.

2009-12-07fast-import: Proper notes tree manipulationLibravatar Johan Herland1-13/+143
This patch teaches 'git fast-import' to automatically organize note objects in a fast-import stream into an appropriate fanout structure. The notes API in notes.h is NOT used to accomplish this, because trying to keep the fast-import and notes data structures in sync would yield a significantly larger patch with higher complexity. Note objects are added with the 'N' command, and accounted for with a per-branch counter, which is used to trigger fanout restructuring when needed. Note that when restructuring the branch tree, _any_ entry whose path consists of 40 hex chars (not including directory separators) will be recognized as a note object. It is therefore not advisable to manipulate note entries with M/D/R/C commands. Since note objects are stored in the same tree structure as other objects, the unloading and reloading of a fast-import branches handle note objects transparently.

2009-12-05fast-import: add (non-)relative-marks featureLibravatar Sverre Rabbelier1-0/+25
After specifying 'feature relative-marks' the paths specified with 'feature import-marks' and 'feature export-marks' are relative to an internal directory in the current repository. In git-fast-import this means that the paths are relative to the '.git/info/fast-import' directory. However, other importers may use a different location. Add 'feature non-relative-marks' to disable this behavior, this way it is possible to, for example, specify the import-marks location as relative, and the export-marks location as non-relative. Also add tests to verify this behavior. Cc: Daniel Barkalow <barkalow@iabervon.org> Signed-off-by: Sverre Rabbelier <srabbelier@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

The --import-marks= option may be specified multiple times on the commandline and should result in all marks being read in. Only one import-marks feature may be specified in the stream, which is overriden by any --import-marks= commandline options.

This subcommand is similar to 'filemodify', except that no mode is supplied (all notes have mode 0644), and the path is set to the hex SHA1 of the given "comittish".

2008-10-13Fix fetch/pull when run without --update-head-okLibravatar Johannes Schindelin1-1/+1
Some confusing tutorials suggested that it would be a good idea to fetch into the current branch with something like this: git fetch origin master:master (or even worse: the same command line with "pull" instead of "fetch"). While it might make sense to store what you want to pull, it typically is plain wrong when the current branch is "master". This should only be allowed when (an incorrect) "git pull origin master:master" tries to work around by giving --update-head-ok to underlying "git fetch", and otherwise we should refuse it, but somewhere along the lines we lost that behavior. The check for the current branch is now _only_ performed in non-bare repositories, which is an improvement from the original behaviour. Some newer tests were depending on the broken behaviour of "git fetch" this patch fixes, and have been adjusted. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Acked-by: Shawn O.

2008-08-17tests: use $TEST_DIRECTORY to refer to the t/ directoryLibravatar Junio C Hamano1-1/+1
Many test scripts assumed that they will start in a 'trash' subdirectory that is a single level down from the t/ directory, and referred to their test vector files by asking for files like "../t9999/expect". This will break if we move the 'trash' subdirectory elsewhere. To solve this, we earlier introduced "$TEST_DIRECTORY" so that they can refer to t/ directory reliably. This finally makes all the tests use it to refer to the outside environment. With this patch, and a one-liner not included here (because it would contradict with what Dscho really wants to do): | diff --git a/t/test-lib.sh b/t/test-lib.sh | index 70ea7e0..60e69e4 100644 | --- a/t/test-lib.sh | +++ b/t/test-lib.sh | @@ -485,7 +485,7 @@ fi | . ../GIT-BUILD-OPTIONS | | # Test repository | -test="trash directory" | +test="trash directory/another level/yet another" | rm -fr "$test" || { | trap - exit | echo >&5 "FATAL: Cannot prepare test area" all the tests still pass, but we would want extra sets of eyeballs on this type of change to really make sure.

Currently fast-import/export cannot be used for repositories with submodules. This patch extends the relevant programs to make them correctly process gitlinks. Links can be represented by two forms of the Modify command: M 160000 SHA1 some/path which sets the link target explicitly, or M 160000 :mark some/path where the mark refers to a commit.

2008-03-08Really make the LF after reset in fast-import optionalLibravatar Adeodato Simó1-0/+2
cmd_from() ends with a call to read_next_command(), which is needed when using cmd_from() from commands where from is not the last element. With reset, however, "from" is the last command, after which the flow returns to the main loop, which calls read_next_command() again. Because of this, always set unread_command_buf in cmd_reset_branch(), even if cmd_from() was successful. Add a test case for this in t9300-fast-import.sh.

2008-02-01Sane use of test_expect_failureLibravatar Junio C Hamano1-12/+12
Originally, test_expect_failure was designed to be the opposite of test_expect_success, but this was a bad decision. Most tests run a series of commands that leads to the single command that needs to be tested, like this: test_expect_{success,failure} 'test title' ' setup1 && setup2 && setup3 && what is to be tested ' And expecting a failure exit from the whole sequence misses the point of writing tests. Your setup$N that are supposed to succeed may have failed without even reaching what you are trying to test. The only valid use of test_expect_failure is to check a trivial single command that is expected to fail, which is a minority in tests of Porcelain-ish commands. This large-ish patch rewrites all uses of test_expect_failure to use test_expect_success and rewrites the condition of what is tested, like this: test_expect_success 'test title' ' setup1 && setup2 && setup3 && ! this command should fail ' test_expect_failure is redefined to serve as a reminder that that test *should* succeed but due to a known breakage in git it currently does not pass. So if git-foo command should create a file 'bar' but you discovered a bug that it doesn't, you can write a test like this: test_expect_failure 'git-foo should create bar' ' rm -f bar && git foo && test -f bar ' This construct acts similar to test_expect_success, but instead of reporting "ok/FAIL" like test_expect_success does, the outcome is reported as "FIXED/still broken".

2007-08-19Allow frontends to bidirectionally communicate with fast-importLibravatar Shawn O. Pearce1-0/+31
The existing checkpoint command is very useful to force fast-import to dump the branches out to disk so that standard Git tools can access them and the objects they refer to. However there was not a way to know when fast-import had finished executing the checkpoint and it was safe to read those refs. The progress command can be used to make fast-import output any message of the frontend's choosing to standard out. The frontend can scan for these messages using select() or poll() to monitor a pipe connected to the standard output of fast-import. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
2007-08-19Make trailing LF optional for all fast-import commandsLibravatar Shawn O. Pearce1-0/+46
For the same reasons as the prior change we want to allow frontends to omit the trailing LF that usually delimits commands. In some cases these just make the input stream more verbose looking than it needs to be, and its just simpler for the frontend developer to get started if our parser is slightly more lenient about where an LF is required and where it isn't. To make this optional LF feature work we now have to buffer up to one line of input in command_buf. This buffering can happen if we look at the current input command but don't recognize it at this point in the code. In such a case we need to "unget" the entire line, but we cannot depend upon the stdio library to let us do ungetc() for that many characters at once. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
2007-08-19Make trailing LF following fast-import `data` commands optionalLibravatar Shawn O. Pearce1-0/+21
A few fast-import frontend developers have found it odd that we require the LF following a `data` command, especially in the exact byte count format. Technically we don't need this LF to parse the stream properly, but having it here does make the stream more readable to humans. We can easily make the LF optional by peeking at the next byte available from the stream and pushing it back into the buffer if its not LF. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
2007-08-19Teach fast-import to ignore lines starting with '#'Libravatar Shawn O. Pearce1-0/+40
Several frontend developers have asked that some form of stream comments be permitted within a fast-import data stream. This way they can include information from their own frontend program about where specific data was taken from in the source system, or about a decision that their frontend may have made while creating the fast-import data stream. This change introduces comments in the Bourne-shell/Tcl/Perl style. Lines starting with '#' are ignored, up to and including the LF. Unlike the above mentioned three languages however we do not look for and ignore leading whitespace. This just simplifies the definition of the comment format and the code that parses them. To make comments work we had to stop using read_next_command() within cmd_data() and directly invoke read_line() during the inline variant of the function. This is necessary to retain any lines of the input data that might otherwise look like a comment to fast-import. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
2007-08-19Actually allow TAG_FIXUP branches in fast-importLibravatar Shawn O. Pearce1-0/+47
Michael Haggerty <mhagger@alum.mit.edu> noticed while debugging a Git backend for cvs2svn that fast-import was barfing when he tried to use "TAG_FIXUP" as a branch name for temporary work needed to cleanup the tree prior to creating an annotated tag object. The reason we were rejecting the branch name was check_ref_format() returns -2 when there are less than 2 '/' characters in the input name. TAG_FIXUP has 0 '/' characters, but is technically just as valid of a ref as HEAD and MERGE_HEAD, so we really should permit it (and any other similar looking name) during import. New test cases have been added to make sure we still detect very wrong branch names (e.g. containing [ or starting with .) and yet still permit reasonable names (e.g. TAG_FIXUP).

2007-07-29git-diff: turn on recursion by defaultLibravatar Jeff King1-1/+1
The tree recursion behavior of git-diff may appear inconsistent to the user because it depends on the format of the patch as well as whether one is diffing between trees or against the index.

2007-07-15Teach fast-import to recursively copy files/directoriesLibravatar Shawn O. Pearce1-0/+83
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.

2007-07-09Support wholesale directory renames in fast-importLibravatar Shawn O. Pearce1-0/+68
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>

2007-05-24Fix possible coredump with fast-import --import-marksLibravatar Shawn O. Pearce1-0/+29
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.

2007-02-12fast-import: Support reusing 'from' and brown paper bag fix reset.Libravatar Shawn O. Pearce1-0/+60
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.

Most users don't need the pack boundary information that fast-import was printing to standard output, especially if they were calling it with --quiet.

2007-02-07Teach fast-import how to clear the internal branch content.Libravatar Shawn O. Pearce1-0/+51
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.

2007-02-06Don't do non-fastforward updates in fast-import.Libravatar Shawn O. Pearce1-0/+80
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>
2007-02-06Support RFC 2822 date parsing in fast-import.Libravatar Shawn O. Pearce1-0/+36
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>
2007-01-18Accept 'inline' file data in fast-import commit structure.Libravatar Shawn O. Pearce1-0/+59
Its very annoying to need to specify the file content ahead of a commit and use marks to connect the individual blobs to the commit's file modification entry, especially if the frontend can't/won't generate the blob SHA1s itself. Instead it would much easier to use if we can accept the blob data at the same time as we receive each file_change line. Now fast-import accepts 'inline' instead of a mark idnum or blob SHA1 within the 'M' type file_change command. If an inline is detected the very next line must be a 'data n' command, supplying the file data. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
2007-01-18Reduce value duplication in t9300-fast-import.Libravatar Shawn O. Pearce1-17/+17
It is error prone to list the value of each file twice, instead we should list the value only once early in the script and reuse the shell variable when we need to access it. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
2007-01-18Create test case for fast-import.Libravatar Shawn O. Pearce1-0/+184
Now that its easier to craft test cases (thanks to 'data <<') we should start to verify fast-import works as expected. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
