2007-12-08

| 03:39 | More comments on sql statements, slight reordering of some tables and conditions. check-in: f7fe15cd0c user: aku tags: trunk | |
| 02:59 | Added comments explaining the select statement checking revision/file/project/metadata integrity check-in: 808fbc4745 user: aku tags: trunk | |
|

| 08:55 | Removed two unused classes. check-in: 97e0e9dda9 user: aku tags: trunk | |

| 04:05 | Reworked time keeping in the pass manager, the microseconds kept by by the 'time' command flow over after roughly 72 minutes (2^32 microseconds). We now use 'clock seconds' to explicitly keep time. This should flow over only after abuut 136 years. The loss of resolution is ok, the converter does not need it. Seconds are good enough. check-in: 9a763fe596 user: aku tags: trunk | |
| 03:58 | Extended traversal core to allow custom labeling of the log output immediately before the traversal starts. check-in: b81901adcb user: aku tags: trunk | |
| 03:56 | Removed the automatic destruction of the traversed graph from the traversal core and put it into the caller (import only, currently). check-in: b59cdc7f8a user: aku tags: trunk | |
| 03:54 | Added progress feedback to the file import, and moved the log output to level 8. check-in: 08f8085700 user: aku tags: trunk | |
| 03:48 | Fixed handling of empty revisions. check-in: bf0b70d5e0 user: aku tags: trunk | |

| 08:07 | Merged mainline into my branch to get the newest application. check-in: d0305b305a 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: 6f1c4424b4 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: d9fc75e587 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. check-in: e100314ec2 user: aku tags: trunk | |
| 07:53 | Integrated the new fossil management class with the option processor. New option --fossil to specify the fossil executable if it was not found in the PATH, or to overide the PATH. check-in: 1a20a81f33 user: aku tags: trunk | |
| 07:52 | Added helper class managing access to fossil repositories. Already has a basic method to import and delta-compress a series of files. Used 'test' commands of fossil to get the necessary low-level access. check-in: b6bf21e2a8 user: aku tags: trunk | |
| 07:50 | Put the graph traversal core of the cycle breaker core into a separate class, for use in other parts of the system. TODO: Rewrite the cycle breaker core in terms of this class. check-in: e701313733 user: aku tags: trunk | |
| 07:47 | Extended project class with method return full path of the project, i.e. inclusive its repository base path. check-in: 82e35d3304 user: aku tags: trunk | |
| 02:29 | Went to explicit var-substitution for the dynamic sql queries, makes formatting easier. check-in: 0ee9711e2e user: aku tags: trunk | |
| 02:25 | Fixed typo, although it did not break anything. check-in: 5b2d15f183 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: 229050721f 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: c4003e7b93 user: aku tags: trunk | |
| 02:21 | Removed lots of now dead code. Added a note to the last remaining user of the changeset method 'nextmap'. check-in: 3c0ef2c379 user: aku tags: trunk | |
|

| 04:54 | Reworked ComputeLimits in the last breaker pass. Moved the heavy computation of the max predecessor / min successor data down to the sql in the changeset class. check-in: 711e000206 user: aku tags: trunk | |
|

| 23:47 | Fluff: Renamed state methods use/reading/writing to usedb/use/extend for clarity. Updated all callers. Extended state module with code to dump the SQL statements it receives to a file for analysis. Extended the 'use' declarations of several passes. check-in: e288af3995 user: aku tags: trunk | |
| 23:45 | Actually put the code for the new pass into the repository. check-in: 060513f2a9 user: aku tags: trunk | |
| 20:06 | 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... check-in: e8c374f670 user: aku tags: trunk | |
| 20:04 | 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 'BreakRevCsetCy... check-in: 00bf8c198e user: aku tags: trunk | |
| 06:58 | Added progress output to the breaking of backward branches. check-in: a437da486d user: aku tags: trunk | |
| 06:57 | Finally committing another disabled integrity constraint for changesets, explanations in the comments. check-in: fd93aa26a6 user: aku tags: trunk | |
| 06:49 | Bugfix. Typo. check-in: c784751485 user: aku tags: trunk | |
| 06:18 | Modified loop check in cycle breaker to abort immediately on first looped changeset. check-in: 487bb1c619 user: aku tags: trunk | |
| 06:17 | Fix table linkage in query, and duplicated conditions :( check-in: f7cca3f082 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 th... check-in: 9c57055025 user: aku tags: trunk | |
| 04:55 | Bugfix. Have the symbol dependency retrieval commands actually return something. check-in: 712010580a 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: ac02614803 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: fbfb531868 user: aku tags: trunk | |
| 03:42 | Fixed typo. Grr. check-in: 0a97ad385a user: aku tags: trunk | |
| 03:41 | Added progress output to the code loading up the graph to traverse, nodes, and arcs. check-in: 41d41c7b57 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: 74854a30b8 user: aku tags: trunk | |

| 18:36 | Bugfix. Handle free-floating branches (their root revision was removed as unnecessary). check-in: 79c227a9c0 user: aku tags: trunk | |
| 18:35 | Helper updated to changes in state definition. check-in: 5bbc7d4c57 user: aku tags: trunk | |
