Ramsay Jones	5418d96ddc	vcs-svn: Fix some printf format compiler warnings In particular, on systems that define uint32_t as an unsigned long, gcc complains as follows: CC vcs-svn/fast_export.o vcs-svn/fast_export.c: In function `fast_export_modify': vcs-svn/fast_export.c:28: warning: unsigned int format, uint32_t arg (arg 2) vcs-svn/fast_export.c:28: warning: int format, uint32_t arg (arg 3) vcs-svn/fast_export.c: In function `fast_export_commit': vcs-svn/fast_export.c:42: warning: int format, uint32_t arg (arg 5) vcs-svn/fast_export.c:62: warning: int format, uint32_t arg (arg 2) vcs-svn/fast_export.c: In function `fast_export_blob': vcs-svn/fast_export.c:72: warning: int format, uint32_t arg (arg 2) vcs-svn/fast_export.c:72: warning: int format, uint32_t arg (arg 3) CC vcs-svn/svndump.o vcs-svn/svndump.c: In function `svndump_read': vcs-svn/svndump.c:260: warning: int format, uint32_t arg (arg 3) In order to suppress the warnings we use the C99 format specifier macros PRIo32 and PRIu32 from <inttypes.h>.

Jonathan Nieder	6117abae56	vcs-svn: Avoid %z in format string In the spirit of v1.6.4-rc0~124 (MinGW: Fix compiler warning in merge-recursive, 2009-05-23), use a 32-bit integer instead; the dump file parser does not support any better, anyway.

Jonathan Nieder	68b4cfbc91	vcs-svn: Rename dirent pool to build on Windows dirent is #define’d to mingw_dirent in compat/mingw.h, with the result that obj_pool_gen(dirent, struct repo_dirent, 4096) creates functions with names like mingw_dirent_alloc and references to dirent_alloc go unresolved. Rename the functions to dent_* to avoid this problem.

David Barr	21746aa34f	SVN dump parser svndump parses data that is in SVN dumpfile format produced by `svnadmin dump` with the help of line_buffer and uses repo_tree and fast_export to emit a git fast-import stream. Based roughly on com.hydrografix.svndump 0.92 from the SvnToCCase project at <http://svn2cc.sarovar.org/>, by Stefan Hegny and others.

David Barr	c0e6c23dca	Infrastructure to write revisions in fast-export format repo_tree maintains the exporter's state and provides a facility to to call fast_export, which writes objects to stdout suitable for consumption by fast-import. The exported functions roughly correspond to Subversion FS operations. . repo_add, repo_modify, repo_copy, repo_replace, and repo_delete update the current commit, based roughly on the corresponding Subversion FS operation. . repo_commit calls out to fast_export to write the current commit to the fast-import stream in stdout. . repo_diff is used by the fast_export module to write the changes for a commit. . repo_reset erases the exporter's state, so valgrind can be happy.

David Barr	3bbaec00a8	Add stream helper library This library provides thread-unsafe fgets()- and fread()-like functions where the caller does not have to supply a buffer.

David Barr	1d73b52f5b	Add string-specific memory pool Intern strings so they can be compared by address and stored without wasting space. This library uses the macros in the obj_pool.h and trp.h to create a memory pool for strings and expose an API for handling them.

Jason Evans	951f316470	Add treap implementation Provide macros to generate a type-specific treap implementation and various functions to operate on it. It uses obj_pool.h to store memory nodes in a treap. Previously committed nodes are never removed from the pool; after any *_commit operation, it is assumed (correctly, in the case of svn-fast-export) that someone else must care about them. Treaps provide a memory-efficient binary search tree structure. Insertion/deletion/search are about as about as fast in the average case as red-black trees and the chances of worst-case behavior are vanishingly small, thanks to (pseudo-)randomness. The bad worst-case behavior is a small price to pay, given that treaps are much simpler to implement. >From http://www.canonware.com/download/trp/trp_hash/trp.h [db: Altered to reference nodes by offset from a common base pointer] [db: Bob Jenkins' hashing implementation dropped for Knuth's] [db: Methods unnecessary for search and insert dropped] [rr: Squelched compiler warnings] [db: Added support for immutable treap nodes] [jn: Reintroduced treap_nsearch(); with tests] Signed-off-by: David Barr <david.barr@cordelta.com> Signed-off-by: Ramkumar Ramachandra <artagnon@gmail.com> Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	15 years ago
David Barr	4709455db3	Add memory pool library Add a memory pool library implemented using C macros. The obj_pool_gen() macro creates a type-specific memory pool. The memory pool library is distinguished from the existing specialized allocators in alloc.c by using a contiguous block for all allocations. This means that on one hand, long-lived pointers have to be written as offsets, since the base address changes as the pool grows, but on the other hand, the entire pool can be easily written to the file system. This could allow the memory pool to persist between runs of an application. For the svn importer, such a facility is useful because each svn revision can copy trees and files from any previous revision. The relevant information for all revisions has to persist somehow to support incremental runs.

Jonathan Nieder	3f527372d9	Introduce vcs-svn lib Teach the build system to build a separate library for the upcoming subversion interop support. The resulting vcs-svn/lib.a does not contain any code, nor is it built during a normal build. This is just scaffolding for later changes.
