2013-07-20use sqlalchemy.textHelmut Grohne
Without using this wrapper the sql statements are not munged by sqlalchemy. Specifically paramstyle is not translated. For sqlite3 this did not matter, because it allows the changed paramstyle, but for postgres it fails without sqlalchemy.text wrappers.
2013-07-17Merge branch master into sqlalchemyHelmut Grohne
This basically pulls the packageid branch into sqlalchemy. The merge was complex, because many sql statements diverged. The merge brings us one step closer to supporting postgres, because an "INSERT OR REPLACE" was removed from readyaml.py in the packageid branch. Conflicts: update_sharing.py webapp.py
2013-07-10use sqlalchemy paramstyleHelmut Grohne
By using the :name syntax inside sql statements, sqlalchemy will replace the contents with whatever paramstyle the underlying dbapi2 module needs. In case of psycopg2 the paramstyle is not qmark for instance.
2013-07-10webapp: fix handling of total_sizeHelmut Grohne
The expression "total_size and 0" masks any positive integer to 0.
2013-07-10schema: reference package table by integer keyHelmut Grohne
One approach to improve performance is to reduce the database size. A package name takes up 15 bytes in average. A number of a package takes up two bytes. Multiply that difference with the number of references and it should be noticeably. A small test set show a reduction by 10%.
2013-06-23Merge master into sqlalchemyHelmut Grohne
This is necessary to avoid severe merge conflicts when converting importpkg.py to sqlalchemy. The actual sql invocation has moved to a different file in master. Conflicts: README (diverged set of dependencies)
2013-06-19webapp: fix hash example link after git uploadHelmut Grohne
The git binary changed and so did its hash. Choosing a more stable example now: The GPL-3.
2013-06-13webapp: use sqlalchemyHelmut Grohne
* Arguably the interface is nicer. * Actually closes connections. => wal files get deleted. * Permits switching from sqlite to anything.
2013-05-09webapp: enrich comparison page with version infoHelmut Grohne
2013-05-05webapp: markup error in /source templateHelmut Grohne
2013-05-02webapp: use jinja's filesizeformatHelmut Grohne
Except it doesn't work, so replace it with our version. At least we might be able to drop this code in a future update.
2013-05-02webapp: reduce size of comparison outputHelmut Grohne
Only add rowspan when it carries a meaning.
2013-04-27webapp: add a css class binary-packageHelmut Grohne
2013-04-25webapp: total_size is None if num_files is 0Helmut Grohne
2013-04-25webapp: turn the <br> after filename into a styleHelmut Grohne
2013-04-25move css to /style.cssHelmut Grohne
2013-04-25webapp: make filenames css styleableHelmut Grohne
2013-04-25webapp: top-align fields in /compare pagesHelmut Grohne
Suggested by Paul Wise.
2013-04-24implement the /compare/pkg1/pkg2 page differentlyHelmut Grohne
The original version had two major drawbacks: 1) The SQL query used would cause a btree sort, so the time waiting for the first output was rather long. 2) For packages with many equal files, the output would grow with O(n^2). Thanks to the suggestions by Christine Grohne and Klaus Aehlig. The approach now groups files in package1 by their main hash value (sha512). It also does some work SQL was designed to solve manually now. To speed up page generation a new caching table was added identifying which files have corresponding shared files.
2013-04-14webapp: added some useful notesHelmut Grohne
2013-03-26webapp: fix problem from the previous mergeHelmut Grohne
2013-03-26Merge branch schemachangeHelmut Grohne
2013-03-20webapp: report correct sizesHelmut Grohne
2013-03-20webapp: remove broken assertHelmut Grohne
Fails on long inputs.
2013-03-09split content table to a hash tableHelmut Grohne
In the old content table (package, filename, size) would be the same for multiple hash functions. Now the schema represents that each file has precisely one size, but multiple hashes.
2013-03-09webapp: drop unused function compute_sharedstatsHelmut Grohne
The sharing table works great and I don't want to adapt it for the next step in the schema change.
2013-03-07integrate the source table into the package tableHelmut Grohne
2013-03-05webapp: added /source/<pkg> pageHelmut Grohne
2013-03-05webapp: helper function function_combinationHelmut Grohne
2013-03-04webapp: fix index templateHelmut Grohne
Apparently not all browsers understand <a ... /> in all rendering modes.
2013-03-04webapp: use caching table "shared" for /binary pageHelmut Grohne
2013-03-04webapp: generate /comparison pages in constant-spaceHelmut Grohne
2013-03-02move fetchiter from webapp to dedup.utilsHelmut Grohne
2013-03-02added html form to main pageHelmut Grohne
Thanks to Jan Luehr for doing the work.
2013-02-25webapp: open database cursor lazilyHelmut Grohne
Makes things more correct when using Application in multiprocessing context.
2013-02-25webapp: pass database to Application classHelmut Grohne
2013-02-25Merge branch 'crosshash'Helmut Grohne
Conflicts in webapp.py: * The fetchall -> fetchiter change caused big conflicts. * New hash combination (image_sha512, image_sha512) added.
2013-02-25webapp: complete cross hash supportHelmut Grohne
2013-02-22webapp: add caching headersHelmut Grohne
2013-02-22webapp: stream responsesHelmut Grohne
Maybe this gets memory usage down for large responses.
2013-02-22webapp: attempt to reduce memory usageHelmut Grohne
2013-02-22webapp: support matching sha512 against gzip_sha512Helmut Grohne
This covers only the /binary page. The comparison may still be empty.
