Unify and refactor exception handling in framework and addons.
The generic `except_osv` is now deprecated, and replaced by more specialized exception subtypes:
- `UserError` (renamed from Warning, as it conflicts with the built-in `Warning`) raised when a non-technical error occurs during a business operation. It could be a missing information in the data provided by the user, or a misconfiguration.
- `AccessError`: raised when any operation is denied because the user conducting it does not have the required access rights.
- `AccessDenied`: raised when an operation that requires authenticated access is attempted via an unauthenticated request.
- `MissingError`: raised when an operation is attempted on a record that does not exist.
- `ValidationError`: raised when an operation violates a SQL or Python constraint.
- All other exceptions are internal errors due to a system problem or bug, and raised untouched to the client-side, which should display a traceback.
All exceptions take a single message argument.
The `test_exceptions` module has been updated to showcase both new and old (deprecated) exceptions.
A great many old `except_osv` had a useless title with "Error!" or "Warning", those have been removed, as this is handled by the client-side widget that displays the messages.
This commit introduces a more consistent policy for logging errors and warnings:
- All messages that do not require administrator attention should be logged at INFO level or lower. This includes all errors that are notified to the user in a friendly manner, even for access right problems or validation errors during business operations.
- All messages that indicate a likely misconfiguration or malicious use by the users should be logged at WARNING level, as they typically require administrator attention.
- All other unhandled internal errors cannot typically be handled by the user and should be logged at ERROR or higher level, as they require immediate administrator attention.
This commit changes the default behavior of `find_in_path`: it doesn't
shallow the IOError exceptions anymore. It especially allows the asset
bundle mechanism to handle the absence of the binaries used to compile
sass/less to css.
* ir_qweb: fallback the value of `get_command` to allow QWeb to display a message like
"Could not execute command lessc"
* ir_qweb: use of `find_in_path` to fetch binaries, allowing to look for binaries
in `bin_path` (Windows releases)
* fixed call of `find_in_path` by `_check_external_dependencies` in
module.py
* fixed call of `find_in_path` by report.py (it was manually raising an
IOError)
Setting the margins of a paperformat to 0mm was ignored and fallbacked on wkhtml
default margins.
This change is considered as relatively safe as margin-* fields have a default
value and setting 0 is then an explicit choice.
Fixes#3367, opw 620130
session.get_file appends the json to the body of the generated iframe and
then tries to json.parse it by reading contentNode on the body.
Exceptions from `report_download` method may contain `<` and `>`, so when
json.parse tries to json.parse the contentNode, it reads only a part of
the original json string. htmlescaping the json string solves the issue
by preventing the content of the json string to be interpreted as html.
commit f76d4525a was not actually working: extra keys from
config files are not yet into the config options dict at
import time. The fix is to move the logic inside the method,
like in `find_pg_tool` just below.
Also fix the use of `find_in_path` in report.py: the subprocess
may also raise AttributeError exception, so instead of listing
all the possible ones just re-raise the IOError shallowed by
`find_in_path` when the result is None.
Fixes#3809#3811
The openerp-server.conf now generates the bin_path record, in order
to resolve calls to external binaries served in the thirdparty dir.
Adpated report.py to use find_in_path and not directly which.
Previously, attachment and attachment_use were only functionnal when used
simultaneously. The code did not consider the fact that the user may want
an historic of all the printed reports. This commit allow the use of
attachment without attachment_use.
It also tell explicitely qweb to generate the branding (used to separate
reports from a unique html when printing multiple reports). Before, it was
functional only when website was installed, because we forced 'editable' that
only has meaning in website.
This module extends web client and reporting tool in order to allow a
preview of PDF files directly in the browser (if supported by the
browser). If you disable it, standard file download stays available.
This commit fixes two different issues specific to Windows:
* NamedTemporaryFile behavior, requiring a file to be closed before being
accessed a second time
* Wkhtmltopdf crash when the document's dpi is inferor to 96
There's a little magic inside the website enabled route modifying the
context's lang, thus breaking the logic to print the report in the
current user's lang. The direct route to display the report should
stay in website_enabled mode, as it allows to switch lang, use the
website translator and so on.
The context may be inconsistent (for instance, containing a group_by associated to another
model). The client will take care of keeping it consistent. Fixes issue #1768
Rebranding has been done in:
- data/demo files
- html templates
- help notices
- comments
- logger messages
- and other various messages

Closes#1260
A squashed merge is required as the conversion of the apiculture branch from
bzr to git was not correctly done. The git history contains irrelevant blobs
and commits. This branch brings a lot of changes and fixes, too many to list
exhaustively.
- New orm api, objects are now used instead of ids
- Environements to encapsulates cr uid context while maintaining backward compatibility
- Field compute attribute is a new object oriented way to define function fields
- Shared browse record cache
- New onchange protocol
- Optional copy flag on fields
- Documentation update
- Dead code cleanup
- Lots of fixes
