| 08:07 | Merged mainline into my branch to get the newest application. (check-in: d0305b30 user: aku tags: trunk) | |
| 07:58 | Bugfix. Translation implies encoding, not the reverse. This caused problems when parsing files with mixed-mode line-endings. The generated char offsets and lengths were off. Found during expansion. (check-in: 6f1c4424 user: aku tags: trunk) | |
| 07:57 | Created new pass for the import of files and changesets. Uses the new file method and fossil accessor class to handle the file import. Changeset -> manifest conversion is _not_ covered yet. (check-in: d9fc75e5 user: aku tags: trunk) | |
| 07:55 | Extended file handling with main logic to import an archive into fossil. Main parts are determining the various orders for expansion and import, and expanding all revisions in an archive into full texts, iteratively applying the stored deltas.

| 02:25 | Fixed typo, although it did not break anything. (check-in: 5b2d15f1 user: aku tags: trunk) | |
| 02:24 | Fixed log progress use in last breaker pass. Disabled the check regarding revision order. It still triggers and I can't see anything wrong. Pressing forward for now, i.e. get the remaining passes done, then revisit this issue. (check-in: 22905072 user: aku tags: trunk) | |
| 02:22 | The handling of detached lines of development (floating branches) still had some bugs regarding the linkage to their revisions, especially the first revision on such branches. Fixed the relevant places, added early integrity checks and updated the main checks to handle the situation. (check-in: c4003e7b user: aku tags: trunk) | |

Importer Status...
Speed. This is now mostly acceptable. The one exception is pass 'BreakAllCsetCycles'. The reason is that the limit computation it does for backward branches still uses the inefficient file-level dependency computation. This will be tackled in short order. For the other passes the file spent is 'CsetsDeps' is recouped by the much faster graph setup. Memory. This seems to be mostly acceptable as well, with the exceptions of 'BreakAllCsetCycles' (again, for reasons see above), and 'InitCsets'. It seems to happen while the pass breaks internal dependencies, but there is no hard data. I have to measure using a memory-debug enabled tclsh. I suspect either the actual internal dependencies, or the pseudo-dependencies. Maybe combined with a bad choice of data structures. Well, measuring first.

The performance was still not satisfying, even with faster recomputing
of successors. Doing it multiple times (Building the graph in each
breaker and sort passes) eats time. Caching in memory blows the
memory. Chosen solution: Cache this information in the database.
Created a new pass 'CsetDeps' which is run between 'InitCsets' and 'BreakRevCsetCycles' (i.e. changeset creation and first breaker pass). It computes the changeset dependencies from the file-level dependencies once and saves the result in the state, in the new table 'cssuccessor'. Now the breaker and sort passes can get the information quickly, with virtually no effort. The dependencies are recomputed incrementally when a changeset is split by one of the breaker passes, for its fragments and its predecessors. The loop check is now trivial, and integrated into the successor computation, with the heavy lifting for the detailed analysis and reporting moved down into the type-dependent SQL queries. The relevant new method is 'loops'. Now that the loop check is incremental the pass based checks have been removed from the integrity module, and the option '--loopcheck' has been eliminated. For paranoia the graph setup and modification code got its loop check reinstated as an assert, redusing the changeset report code. Renumbered the breaker and sort passes. A number of p... (check-in: 00bf8c19 user: aku tags: trunk) | |
| 06:58 | Added progress output to the breaking of backward branches. (check-in: a437da48 user: aku tags: trunk) | |
| 06:57 | Finally committing another disabled integrity constraint for changesets, explanations in the comments. (check-in: fd93aa26 user: aku tags: trunk) | |
| 06:49 | Bugfix. Typo. (check-in: c7847514 user: aku tags: trunk) | |
| 06:18 | Modified loop check in cycle breaker to abort immediately on first looped changeset. (check-in: 487bb1c6 user: aku tags: trunk) | |
| 06:17 | Fix table linkage in query, and duplicated conditions :( (check-in: f7cca3f0 user: aku tags: trunk) | |
| 05:49 | Performance bugfix. nextmap/premap can still be performance killers and memory hogs. Moved the computation of sucessor changesets down to the type-dependent code (new methods) and the SQL database, i.e. the C level. In the current setup it was possible that the DB would deliver us millions of file-level dependency pairs which the Tcl level would then reduce to tens of actual changeset dependencies. Tcl did not cope well with that amount of data. Now the reduction happens in the query itself. A concrete example was a branch in the Tcl CVS generating nearly 9 million pairs, which reduced to roughly 200 changeset dependencies. This blew the memory out of the water and the converter ground to a halt, busily swapping. Ok, causes behind us, also added another index on 'csitem(iid)' to speed the search for changesets from the revisions, tags, and branches. (check-in: 9c570550 user: aku tags: trunk) | |
| 04:55 | Bugfix. Have the symbol dependency retrieval commands actually return something. (check-in: 71201058 user: aku tags: trunk) | |
| 03:49 | Deactivated caching of the nextmap/premap data, with the indices the retrieval seems to be fast enough to allow us to reduce mem consumption. Tweaked log output, and sql formatting. (check-in: ac026148 user: aku tags: trunk) | |
| 03:46 | Bugfix in ValidateFragments, tweaked comment a bit, bugfix in SQL, reordered tables in the successor/predecessor queries a bit to show the actual progression of their use. (check-in: fbfb5318 user: aku tags: trunk) | |
| 03:42 | Fixed typo. Grr. (check-in: 0a97ad38 user: aku tags: trunk) | |
| 03:41 | Added progress output to the code loading up the graph to traverse, nodes, and arcs. (check-in: 41d41c7b user: aku tags: trunk) | |
| 03:40 | Added ability to declare indices on tables in the persistent state. Used this to declare indices on critical columns. Slows down the transactions saving changesets, this however is made up when it comes to successor/predecessor retrieval of changesets. (check-in: 74854a30 user: aku tags: trunk) | |

| 15:20 | Fixed typo of keyword. (check-in: 3db03be6 user: aku tags: trunk) | |
| 06:57 | Easier name for self-referential changesets, loopcheck. Made conditional on option --loopcheck, default off, and avoided if the general checks on changesets report trouble. Reinstated the loop check in the cycle breaker core in simpler form, reusing the new command in the changeset class. (check-in: 0af7a3c8 user: aku tags: trunk) | |
| 06:50 | Moved the integrity checks for split fragments into separate command. Reworked breaking of internal dependencies to contrain the length of the pending list. That part of the system is still a memory hog, especially for large changesets. Added notes about this and the successor retrieval being a bottleneck. (check-in: c14e8f84 user: aku tags: trunk) | |
| 04:27 | Fixed bug in new changeset code, tagged and untagged item lists went out of sync. (check-in: facb4a87 user: aku tags: trunk) | |
| 03:57 | Replaced the checks for self-referential changesets in the cycle breaker with a scheme in the changeset class doing checks when splitting a changeset, which is also called by the general changeset integrity code, after each pass. Extended log output at high verbosity levels. Thorough checking of the fragments a changeset is to be split into. (check-in: b42cff97 user: aku tags: trunk) | |

| 07:36 | Brought the variable names into alignment with the semantics, now again naming what is stored in them. (check-in: deab4d03 user: aku tags: trunk) | |
| 07:24 | Reworked the in-memory databases of changesets. Objects now hold items, not only revisions. Tags, and branches are new possibilities. Lists of ids go to the type-dependent retrieval command. List of tagged items (type/id pairs) come back, and are in the API. The 1:n map revisions to changesets is now an 1:1-map tagged items to changeset. (check-in: 0fcfbf78 user: aku tags: trunk) | |
| 07:02 | Implemented time ranges and dependency retrieval for the tag and branch based changesets. (check-in: b1666f8f user: aku tags: trunk) | |
| 06:58 | Moved the existing successor/predecessor code from main class to the proper singleton. Fixed config of main class, isn't simple dispatch any longer. Simplified calculation of the readable representation of changesets and removed code which has become superfluous. (check-in: 70d22835 user: aku tags: trunk) | |
| 06:47 | Added equivalent checks for the tag and branch based changesets. (check-in: 4b15fa34 user: aku tags: trunk) | |

This commit starts a series of incremental changes not quite
completely overhauling the handling of changesets, i.e. of
project-level revisions. Actually this series of changes already
started with [8ce7ffff21] as the bug it fixes was found when the first
parts of the overhaul tripped the new integrity conditions for the
modified changesets.
Background: In the last few days I repeatedly ran against the wall of an assertion in pass 9, last of the cycle breakers, with the revision changesets coming in out of order when the symbols were added to the dependency graph. While walking to the office, and later re-reading the relevant parts of cvs2svn again I had several insights. Trigger was the realization that giving the tag changesets successor dependencies was wrong. Tags describe a state, they have no successors. This caused the re-read, and I recognized that my handling of the symbol changesets was completely wrong, that with using revisions as their data. It should have been the tags and branches. From there their actual dependencies (versus my reuse of revision dependencies) fell out naturally. I have decided to commit my rewrite of the internals incrementally to make it easier to follow them, despite leaving the sourcebase in an unusable state during the series. One big commit would be much more difficult to understand. The... (check-in: 27b15b70 user: aku tags: trunk) | |

| 05:39 | Added convenience method for assertions and used it in place of the existing if/trouble internal constructions. Changed API of 'log write' so that we can defer substituation of the message to when the write actually happen, and converted all places which would be hit by double-substitution. The remaining 'log write' calls will be converted incrementally. (check-in: 47d52d1e user: aku tags: trunk) | |

Both helpers look at the tree of symbols and show it in toto (symbol tree), or restrict themselves to the branches, aka lines of development (lodtree). (check-in: b8c35421 user: aku tags: trunk) | |

| 06:03 | Fixed the calculation of possible parents for a detached NTDB. Has to be trunk. The symbols were skipped before, causing them to have no parents at all later on, forcing an abort after CollateSymbols. Added some high verbosity log commands for debugging of this area. (check-in: 930ec162 user: aku tags: trunk) | |

| 03:47 | Continued work on pass 8. Renamed 'retrograde' to 'Backward Branch', should be easier to understand, and completed the predicate testing if a branch changeset is backward or not. (check-in: 4f1b60dd user: aku tags: trunk) | |
| 03:33 | Continued work on pass 8, added outline for handling of retrograde branches, extended changesets with predicate allowing us to find the branch changesets. (check-in: 4866889e user: aku tags: trunk) | |
| 03:21 | Extended changeset class with in-memory database mapping from changeset ids to the proper object, and extended the objects with position information and associated accessors. Extended pass 8 to load the commit order computed in pass 6, this is stored in the new position slot of changesets, and an inverted index mapping from position to changeset at that position. (check-in: de4cff41 user: aku tags: trunk) | |
| 03:11 | Modified the API for the construction of changesets a bit, now allowing their construction with the correct id, instead of correcting it later. Updated pass 5 to use this, and fixed bug where the id counter for changesets was left uninitialized, allowing the improper generation of duplicate ids. (check-in: 65be27aa user: aku tags: trunk) | |
| 03:03 | Reworked the cycle breaker internals, moving the code handling the replacement of a changset (= node) with its fragments into a separate command. Extended the API, exposing the replacement operation, for use by passes. Added debugging code showing the set of consumable nodes for each iteration. (check-in: ad7d5c2d user: aku tags: trunk) | |
| 02:58 | Moved the functionality for splitting a changeset based on the sets of revisions for the fragments to be into a separate command, and into the changeset class, for use outside of changeset links. (check-in: 59207428 user: aku tags: trunk) | |

First corrected variable names, I forgot to use the standard 'myXXX' format for the typevariables. Second, fixed a bug uncovered by looking at the exported graphs, which caused the system to loose arcs, possibly breaking cycles without actually breaking them, leaving them in the dependencies.

| 04:17 | Completed pass 7, breaking dependency cycles over symbol changesets. Moved the bulk of the cycle breaker code into its own class as it was common to the passes 6 and 7, and updated the two passes accordingly. Added code to load the changeset counter from the state to start properly. (check-in: 770a9b57 user: aku tags: trunk) | |
| 03:59 | Bugfix. When setting up or extended the changeset graph a changeset's successor may lay outside of the set of changesets under consideration, i.e. without a node in the graph. Ignore these. This did not (or only rarely) happen before the bugfix to the successor computation of changesets in project::rev (list instead of single). (check-in: de64c94f user: aku tags: trunk) | |
| 03:54 | Bugfix. When I introduced the 'revisionbranchchildren' table to pass 2 I forgot to update pass 4 as well. Added code to drop the excluded revisons from this table as well, as either parent of branches, or branch child of some other revision. (check-in: 2516f4a5 user: aku tags: trunk) | |

| 05:11 | Completed pass 6, wrote the code performing the breaking of cycles. Done by analysing each triple of changesets in the cycle at the file dependency level to see which revisions can be sorted apart. Added some additional utility routines. Extended the changeset class with the accessors required by the cycle breaker. (check-in: 94c39d63 user: aku tags: trunk) | |
| 05:08 | Fixed handling of project objects when persisting them. Fill the project map. This is needed if the pass is not skipped. For the skip case we already initialize the project map when 'load'ing from the state. (check-in: 67600f77 user: aku tags: trunk) | |

| 07:22 | Continued work on pass 6. Completed creation of changeset graph (nodes, dependencies), started on topological iteration and breaking cycles. Basic iteration is complete, fiding a cycle ditto. Not yet done is to actually break a found cycle. Extended the changeset class with the necessary accessor methods (getting cset type, successors, time range). Note: Looking at my code it may be that my decision to save the cset order caused this pass to subsume the RevisionTopologicalSortPass of cvs2svn. Check again when I am done. Note 2: The test case (tcl repository, tcl project) had no cycles. (check-in: 85bd219d user: aku tags: trunk) | |

| 23:44 | Rewrote the algorithm for breaking internal dependencies to my liking. The complex part handling multiple splits has moved from the pass code to the changeset class itself, reusing the state computed for the first split. The state is a bit more complex to allow for its incremental update after a break has been done. Factored major pieces into separate procedures to keep the highlevel code readable. Added lots of official log output to help debugging in case of trouble. (check-in: 08ebab80 user: aku tags: trunk) | |
| 20:40 | Oops. pass 5 is not complete. Missed the breaking of internal dependencies, this is done in this pass already. Extended pass _2_ and file revisions with code to save the branchchildren (possible dependencies), and pass 5 and changesets with the proper algorithm. From cvs2svn, works, do not truly like it, as it throws away and recomputes a lot of state after each split of a cset. Could update and reuse the state to perform all splits in one go. Will try that next, for now we have a working form in the code base. (check-in: 95af789e user: aku tags: trunk) | |

Now only missing piece is replication of the pass 2 paranoia checks. Note: Checks in the adjustment of parents are a bottleneck. May need indices, or something we can do in memory. (check-in: 37734390 user: aku tags: trunk) | |

Extended project::sym class with in-memkory databases to hold the option information and replaced the 'UserConfig' placeholder with the actual code using the new databases to determine symbol types based on user-requests. Extended the pass itself with code performing various checks on the results of type determination, partially paranoia, partially to find genuine bad requests (excluding symbols with unexcluded blockers, making a symbol with commits on it a tag, ...). NYI: Computation of the prefered parent for all symbols. (check-in: 7eaa420a user: aku tags: trunk) | |
