Since zodbdump start (c0a6299f "zodbdump - Tool to dump content of a ZODB database (draft)") and up till now zodbdump output format was not good. For example user and description transaction properties were output without proper quoting, which in situation when there would be fancy characters in there would break the output. So start the format stabilization: - user and description are output as quoted, so now they are guaranteed to be on one line. The quoting character is always " (instead of e.g. smartly quoting either by ' or " as python does) for easier compatibility with ZODB implementations in other languages. - transaction extension is now printed as raw bytes, not as dict. The idea here is that `zodb dump` * should perform dump of raw data as stored inside ZODB so that later `zodb restore` could restore the database identically to the same state. * we should dump raw data instead of unpickled ones because generally on-disk extension's format can be any raw bytes and this information should be preserved. - transaction status is now also output as quoted to preserve line breakage on fancy status codes. - it is documented that sha1 is not the only allowed hash function that might be used. - in hashonly mode we add trailing " -" to obj string so that it is possible to distinguish outputs of `zodb dump` and `zodb dump -hashonly` without knowing a-priory the way it was produced. The reason to do so is that it would be not good to e.g. by accident feed hashonly output to (future) `zodb restore`, which, without having a way to see it should not consume object data would read following transaction information as raw object data with confusing later errors (and a small chance to restore completely different database without reporting error at all). Because ZODB iteration API gives us already unpickled extension and only that, for now to dump it as raw we get a long road to pickle it back also caring to try to pickle in stable order. Hopefully this will be only a fallback because of https://github.com/zopefoundation/ZODB/pull/183 and next zodbtools patch. ~~~~ For testing purposes (currently only quoting function unit test) py.test usage is introduced. The code is also generally polished here and there.

Hello up there. Recently with Ivan we needed a way to obtain last transaction ID of a ZODB storage for resiliency checking. For this `zodb info` utility to print general information about a ZODB database is introduced. Along the way, as it was already planned, all zodbtools utilities are now covered by only one `zodb` command which can invoke other subcommands and show help topics. I also used the occassion to switch how storages are specified from being ZConfig-file-always to be specified by URL e.g. neo://neo1@127.0.0.1:24573 zeo://... file://... without loosing generality because zconfig:// scheme is also supported. Please find more details about all changes in individal commit messages. Thanks for feedback, Kirill /cc @kazuhiko, @jm, @vpelletier, @jerome, @Tyagov, @klaus, @alain.takoudjou, @rafael /reviewed-on nexedi/zodbtools!2

Either all general parameters at once: $ zodb info neo://neo1@127.0.0.1:24573 name=NEOStorage(neo1) size=0 last_tid=03be7484ddc7f6ee or one particular parameter: $ zodb info neo://neo1@127.0.0.1:24573 last_tid 03be7484ddc7f6ee

Most of our tools need only read access for working. However e.g. FileStorage, when opened in read-write mode, automatically creates database file and index. This way if database is opened in read-write mode a simple typo in path, e.g. to `zodb dump path` would lead to: - new database at path will be created - the dump will print nothing (empty database) - exit status will be 0 (ok) and no error will be reported. For this reason it is better tools declare access level they need so for read-only access request we can catch it with an error from storage. This, however, requires quite recent ZODB to work: https://github.com/zopefoundation/ZODB/pull/153 P.S. We don't want to force users to always specify read-only in URLs or zconf files because: - this is error prone - URL or zconf can be though as of file - when a program opens a file the program, not file, declares which type of access it wants. That's why access mode declaration has to be internal.

Previously for specifying a storage we were requiring users to create zconfig file and put information about storage there. This is not always convenient e.g. for quickly inspecting a file storage or a NEO instance here and there for which address and name is already at hand. So thanks to zodburi we can switch to specifying storages by URL without loosing generality as there is still zconfig:// schema which allows to configure storages zconfig way. P.S. for convenience we allow paths without schema to be treated as FileStorage (i.e. file:// schema is implicitly used). P.P.S. zodbanalyze is not affected (for now ?) as it currently works with FileStorage only. [1] http://docs.pylonsproject.org/projects/zodburi/

We already have 3 commands in zodbtools suite (zodbanalyze, zodbdump & zodbcmp) and this is going to grow. And it was already noted some time ago with TODO (in 66946b8d) that we need only one command driver to invoke everything. So do it: introduce `zodb` command which can invoke other subcommands and show general help or help for subcommand or a topic. The structure is modelled after `git` and `go` commands. Help topics are for now empty but we'll add one help topic in the next patch.

- Nexedi adheres to GPLv3+ with wide exception for Free/Open-source software. Use this for our original work. - Zodbanalyze was initially developed by Zope corp & co. See d86d04dc (initial copy of ZODB3-3.9.7's ZODB/scripts/analyze.py.) ab17cf2d (Hook in Nexedi's zodbanalyze) So follow original Zope's licensing terms for zodbanalyze.

The package was named zodbtools from start (see fd6ad1b9 "Start of zodbtools.git"). However in 66a03ae5 I've made a thinko naming some parts as zodbtool. Fix the confusion and name things uniformly as zodbtools. /reviewed-by TrustMe

This is enhanced version of ZODB original scripts/analyze.py . Nexedi version was originally developed as part of ERP5 here: https://lab.nexedi.com/nexedi/erp5/commits/master/erp5/util/zodbanalyze It was agreed to move zodbanalyze to zodbutils /see slapos!116

This is a tool to compare two ZODB databases in between tidmin..tidmax transaction range with default range being -∞..+∞ - (whole database). For comparision both databases are scanned at storage layer and every transaction content is compared bit-to-bit between the two. The program stops either at first difference found, or when whole requested transaction range is scanned with no difference detected. Database storages are specified in files with ZConfig-based storage definition, e.g. %import neo.client <NEOStorage> master_nodes ... name ... </NEOStorage> Please see nexedi/neoppod!4 for one of possible contexts. The tool is generic though and is not NEO-specific. It should be able to even check two different storages like ZEO & NEO, or FileStorage and NEO etc and thus can be handy. TODO tests

Project to be a place for various ZODB utilitieis. Jim Fulton suggested to have it separate from ZODB/scripts/ [1] and now we have it here. [1] https://github.com/zopefoundation/ZODB/pull/128#issuecomment-260970932
