Shawn O. Pearce	c44cdc7eef	Converted fast-import to a text based protocol. Frontend clients can now send a text stream to fast-import rather than a binary stream. This should facilitate developing frontend software as the data stream is easier to view, manipulate and debug my hand and Mark-I eyeball. Signed-off-by: Shawn O.

Shawn O. Pearce	7111feede9	Implement blob ID validation in fast-import. When accepting revision SHA1 IDs from the frontend verify the SHA1 actually refers to a blob and is known to exist. Its an error to use a SHA1 in a tree if the blob doesn't exist as this would cause git-fsck-objects to report a missing blob should the pack get closed without the blob being appended into it or a subsequent pack. So right now we'll just ask that the frontend "pre-declare" any blobs it wants to use in a tree before it can use them. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago
Shawn O. Pearce	463acbe1c6	Added tree and commit writing to fast-import. The tree of the current commit can be altered by file_change commands before the commit gets written to the pack. The file changes are rather primitive as they simply allow removal of a tree entry or setting/adding a tree entry. Currently trees and commits aren't being deltafied when written to the pack and branch reloading from the current pack doesn't work, so at most 5 branches can be worked with at any one time.

Shawn O. Pearce	6bb5b3291d	Implemented branch handling and basic tree support in fast-import. This provides the basic data structures needed to store trees in memory while we are processing them for a branch. What we are attempting to do is track one complete tree for each branch that the frontend has registered with us through the 'newb' (new_branch) command. When the frontend edits that tree through 'updf' or 'delf' commands we'll mark the affected tree(s) as being dirty and recompute their objects during 'comt' (commit). Currently the protocol is decidedly _not_ user friendly. I crashed fast-import by giving it bad input data from Perl. I may try to improve upon it, or at least upon its error handling.

Shawn O. Pearce	6143f0644e	Added basic command handler to fast-import. Moved the new_blob logic off into a new subroutine and invoked it when getting the 'blob' command. Added statistics dump to STDERR when the program terminates listing what it did at a high level. This is somewhat interesting. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago
Shawn O. Pearce	ac47a738a7	Refactored fast-import's internals for future additions. Too many globals variables were being used not not enough code was resuable to process trees and commits so this is a simple refactoring of the existing blob processing code to get into a state that will be easier to handle trees and commits in.

Shawn O. Pearce	27d6d29035	Cleaned up memory allocation for object_entry structs. Although its easy to ask the user to tell us how many objects they will need, its probably better to dynamically grow the object table in large units. But if the user can give us a hint as to roughly how many objects then we can still use it during startup. Also stopped printing the SHA1 strings to stdout as no user is currently making use of that facility. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago
Shawn O. Pearce	8bcce30126	Added automatic index generation to fast-import. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago
Shawn O. Pearce	db5e523fdd	Created fast-import, a tool to quickly generating a pack from blobs. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	18 years ago
