Shawn O. Pearce	e8438420bb	Allow fast-import frontends to reload the marks table I'm giving fast-import a lesson on how to reload the marks table using the same format it outputs with --export-marks. This way a frontend can reload the marks table from a prior import, making incremental imports less painful. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago

Shawn O. Pearce	ea5e370aa9	fast-import: Support reusing 'from' and brown paper bag fix reset. 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.

Shawn O. Pearce	c73461567e	fast-import: Add tip about importing renames. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago
Shawn O. Pearce	bdf1c06dc1	fast-import: Hide the pack boundary commits by default. 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. Those users who do want this information probably want it captured so they can go back and use it to repack the imported repository. So dumping the boundary commits to a log file makes more sense then printing them to standard output. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago
Shawn O. Pearce	882227f117	Correct spelling of fast-import in docs. Its spelled 'fast-import', not 'gfi'. Linus and Dscho have both recently pointed this out to me on the mailing list. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago
Shawn O. Pearce	f842fdb01d	Correct some language in fast-import documentation. Minor documentation improvements, as suggested on the Git mailing list by Horst H. von Brand and Karl Hasselström. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago
Shawn O. Pearce	209f129857	Correct ^0 asciidoc syntax in fast-import docs. I wrote this documentation with asciidoc 7.1.2, but apparently asciidoc 8 assumes ^ means superscript. The solution was already documented in rev-parse's manpage and is to use {caret} instead. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago
Shawn O. Pearce	bdd9f4240f	Add a Tips and Tricks section to fast-import's manual. There has been some informative lessons learned in the gfi user community, and these really should be written down and documented for future generations of frontend developers.

Shawn O. Pearce	820b931012	Dump all refs and marks during a checkpoint in fast-import. If the frontend asks us to checkpoint (via the explicit checkpoint command) its probably because they are afraid the current import will crash/fail/whatever and want to make sure they can pickup from the last checkpoint. To do that sort of recovery, we will need the current tip of every branch and tag available at the next startup. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago
Shawn O. Pearce	c499d76849	Teach fast-import how to sit quietly in the corner. Often users will be running fast-import from within a larger frontend process, and this may be a frequent periodic tool such as a future edition of `git-svn fetch`. We don't want to bombard users with our large stats output if they won't be interested in it, so `--quiet` is now an option to make gfi be more silent. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago
Shawn O. Pearce	825769a8fe	Teach fast-import how to clear the internal branch content. 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.

Shawn O. Pearce	9b92c82fde	Minor timestamp related documentation corrections for fast-import. As discussed on the mailing list, the documentation used here was not quite accurate. Improve upon it. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago

Shawn O. Pearce	7073e69e38	Don't do non-fastforward updates in fast-import. 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>	18 years ago
Shawn O. Pearce	63e0c8b364	Support RFC 2822 date parsing in fast-import. 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>	18 years ago
Shawn O. Pearce	ef94edb53c	Minor fast-import documentation corrections. Corrected a couple of header markup lines which were shorter than the actual header, and made the `data` commands two formats into a named list, which matches how we document the two formats of the `M` command within a commit. Also tried to simplify the language about our decimal integer format; Linus pointed out I was probably being too specific at the cost of reduced readability. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago
Shawn O. Pearce	c74ba3d344	Correct fast-import timezone documentation. Andy Parkins and Linus Torvalds both noticed that the description of the timezone was incorrect. Its not expressed in minutes. Its more like "hhmm", where "hh" is the number of hours and "mm" is the number of minutes shifted from GMT/UTC. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago
Shawn O. Pearce	0b868e0240	Remove --branch-log from fast-import. The --branch-log option and its associated code hasn't been used in several months, as its not really very useful for debugging fast-import or a frontend. I don't plan on supporting it in this state long-term, so I'm killing it now before it gets distributed to a wider audience. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago
Shawn O. Pearce	6e411d2044	Initial draft of fast-import documentation. This is a first pass at the manpage for git-fast-import. I have tried to cover the input format in extreme detail, creating a reference which is more detailed than the BNF grammar appearing in the header of fast-import.c. I have also covered some details about gfi's performance and memory utilization, as well as the average learning curve required to create a gfi frontend application (as it is far lower than it might appear on first glance). The documentation still lacks real example input streams, which may turn out to be difficult to format in asciidoc due to the blank lines which carry meaning within the format.
