[issue19512] Avoid temporary Unicode strings, use identifiers to only create the string once
Serhiy Storchaka added the comment: What is the problem with these changes? Usually CPython team avoids code churn without serious reasons. Performance reasons for the change PySys_GetObject(stdout) to _PySys_GetObjectId(_PyId_stdout) are ridiculous. You changed hundreds lines of code for speed up interactive mode by perhaps several microseconds. Errors become more unlikely because objects are only initialized once, near startup. So it put also less pressure on code handling errors :) (it is usually the least tested part of the code) If there are bugs in code handling errors, they should be fixed in maintenance releases too. You mean for PyRun_InteractiveOneObject()? Oh, it can be made private, but what is the problem of adding yet another PyRun_Interactive*() function? There are already a lot of them :-) And this is a problem. Newly added function is not even documented. I also worked hard to support unencodable filenames: using char*, you cannot support arbitrary Unicode filename on Windows. That's why a added many various functions with Object suffix. Some examples: PyWarn_ExplicitObject(), PyParser_ParseStringObject(), PyImport_AddModuleObject(), etc. One bug per bug report as Martin says. Another problem is that PyUnicode_FromString() failure is not handled correctly in some cases. PyUnicode_FromString() can fail because an decoder error, but also because of a MemoryError. It can't fail on stdout because an decoder error. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19512 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue19517] sysconfig variables introduced by PEP-3149 are currently undocumented
New submission from Yury V. Zaytsev:
PEP-3149 (issue9193) introduces new variables (SO and SOABI) so that one can
find out what are the supported extension suffixes.
Quote from the PEP:
sysconfig.get_config_var('SO')
'.cpython-32mu.so'
sysconfig.get_config_var('SOABI')
'cpython-32mu'
Later, in issue16754, doko introduced EXT_SUFFIX SHLIB_SUFFIX and planned to
update the PEP, but this didn't happen. This caused discrepancy in the news
(issue11234), and the news item was fixed:
http://docs.python.org/3.4/whatsnew/3.2.html?highlight=soabi
sysconfig.get_config_var('SOABI') # find the version tag
'cpython-32mu'
sysconfig.get_config_var('EXT_SUFFIX') # find the full filename extension
'.cpython-32mu.so'
However, the PEP is still not up-to-date and is in conflict with the
implementation.
In an IRC discussion with Barry he suggested that PEPs shouldn't be considered
documentation, so updating the PEP is not the right way to go.
My proposal is then to document the intent behind SO, SOABI, EXT_SUFFIX
SHLIB_SUFFIX on the sysconfig documentation page and mention that they are
platform-specific, and maybe add a link to this page to the PEP.
As of now, I find the situation highly confusing... Any opinions or suggestions
please?
Thanks,
Z.

[issue16286] Use hash if available to optimize a==b and a!=b for bytes and str
STINNER Victor added the comment: I added recently a new _PyUnicode_CompareWithId() function: changeset 77bebcf5c4cf (issue #19512). This function can be used instead of PyUnicode_CompareWithASCIIString() when the right parameter is a common string. It is interesting when the right string is probably present in a dictionary. For example, path is always present as sys.path. So interning the string doesn't eat more memory. _PyUnicode_CompareWithId() would be more efficient with compare_hash-3.patch. The function is not used yet in critical path. It is now used in type_new() for example. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16286 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue19518] Add new PyRun_xxx() functions to not encode the filename
New submission from STINNER Victor: The changeset af822a6c9faf of the issue #19512 added the function PyRun_InteractiveOneObject(). By the way, I forgot to document this function. This issue is also a reminder for that. The purpose of the new function is to avoid creation of temporary Unicode strings and useless call to Unicode encoder/decoder. I propose to generalize the change to other PyRun_xxx() functions. Attached patch adds the following functions: - PyRun_AnyFileObject() - PyRun_SimpleFileObject() - PyRun_InteractiveLoopObject() - PyRun_FileObject() On Windows, these changes should allow to pass an unencodable filename on the command line (ex: japanese script name on an english setup).

That would be more robust, as it could complain any time unicode.encode produced unicode and str.decode produced str and point users to the codecs module level functions as a forward compatible alternative.

[issue1820] Enhance Object/structseq.c to match namedtuple and tuple api
Sunny K added the comment: New patch for 3.4 adds the following: 1. _fields 2. _replace() 3. _asdict() 4. eval(repr(s)) == s Now the issues: 1. _asdict() returns a normal dictionary. I don't know if this is what is required. 2. Both _asdict() and _replace() assume that unnamed visible fields are at the end of the visible sequence. A comment at the beginning says they are allowed for indices n_visible_fields. Is there another way to map members to values? Because tp-members is (visible named fields + invisible named fields) whereas values array is (visible named fields + visible unnamed fields + invisible named fields) 3. The mismatch mentioned above is present in the current implementation of repr: In os.stat_result, the last three visible fields are unnamed (i.e integer a_time, m_time and c_time). However they are present in the repr output with keys which are the first three keys from the invisible part(float a_time, m_time and c_time). Was this intentional? Also, the above logic causes duplicate keys when invisible fields are included in the repr output as per issue11629. In my patch for that issue, i put invisible fields under the 'dict' keyword argument. This output format utilises code already present in structseq_new and makes eval work as expected when invisible fields are present in repr. Also, it sidesteps the question of duplicated keys because they are present inside a dict. 4. Raymond stated that _fields should contain only the visible positional fields. So _fields of os.stat_result contains only 7 fields because of the three unnamed fields. Is this the expected implementation? 5. Is there a way to declare a member function in C that accepts only keyword arguments(like _replace())? I could not find one. This is my first real C patch. So some of the issues might just be a lack of understanding.

[issue19519] Parser: don't transcode input string to UTF-8 if it is already encoded to UTF-8
New submission from STINNER Victor: Python parser (Parser/tokenizer.c) has a translate_into_utf8() function to decode a string from the input encoding and encode it to UTF-8. This function is unnecessary if the input string is already encoded to UTF-8, which is something common nowadays. Linux, Mac OS X and many other operating systems are now using UTF-8 as the default locale encoding, UTF-8 is the default encoding for Python scripts, etc. compile(), eval() and exec() functions pass UTF-8 encoded strings to the parser. Attached patch adds an input_is_utf8 flag to the tokenizer to skip translate_into_utf8() if the input string is already encoded to UTF-8. -- files: input_is_utf8.patch keywords: patch messages: 202331 nosy: benjamin.peterson, haypo, serhiy.storchaka priority: normal severity: normal status: open title: Parser: don't transcode input string to UTF-8 if it is already encoded to UTF-8 type: performance versions: Python 3.4 Added file: http://bugs.python.org/file32526/input_is_utf8.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19519 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue11698] Improve repr for structseq objects to show named, but unindexed fields
Sunny K added the comment:
The previous patch had a wrong mapping between keys and values. The
current implementation of repr means that duplicated keys will be
present when invisible fields are included. See points 2 and 3 in
http://bugs.python.org/issue1820#msg202330 for more explanation.
I have sidestepped that issue by placing invisible fields under the dict
argument. This also plays well with the current code in
structseq_new and eval(repr(obj)) works.
The output with the patch is:
$./python -c import os; print(os.stat('LICENSE'))

[issue19518] Add new PyRun_xxx() functions to not encode the filename
STINNER Victor added the comment: 2013/11/7 Serhiy Storchaka rep...@bugs.python.org: On Windows, these changes should allow to pass an unencodable filename on the command line (ex: japanese script name on an english setup). Doesn't the surrogateescape error handler solve this issue? surrogateescape is very specific to UNIX, or more generally systems using bytes filenames. Windows native type for filename is Unicode. To support any Unicode filename on Windows, you must never encode a filename. surrogateescape avoids decoding errors, here is the problem is an encoding error. For example, abé cannot be encoded to ASCII. abé.encode(ascii, surrogateescape) doesn't help here. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19518 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue19512] Avoid temporary Unicode strings, use identifiers to only create the string once
STINNER Victor added the comment: Errors become more unlikely because objects are only initialized once, near startup. So it put also less pressure on code handling errors :) (it is usually the least tested part of the code) If there are bugs in code handling errors, they should be fixed in maintenance releases too. Well, using identifiers doesn't solve directly all issues. For example, _PyDict_GetItemId() should be replaced with _PyDict_GetItemIdWithError() to be complelty safe. It just reduces the probability of bugs. Using identifiers might add regressions for a minor gain (handling MemoryError better). As I did for issues #18048 and #19437 (related to issues found by failmalloc), I prefer to not backport such minor bugfixes to not risk a regression. You changed hundreds lines of code for speed up interactive mode by perhaps several microseconds. Again, performance is not the main motivation, please read again msg202293. Or maybe you disagree with this message? Sorry, I didn't explain my changes in first messages of this issue. I created the issue to group my changesets to an issue, to explain why I did them.

[issue19519] Parser: don't transcode input string to UTF-8 if it is already encoded to UTF-8
STINNER Victor added the comment: The parser should check that the input is actually valid UTF-8 data. Ah yes, correct. It looks like input data is still checked for valid UTF-8 data. I suppose that the byte strings should be decoded from UTF-8 because Python 3 manipulates Unicode strings, not byte strings. The patch only skips calls to translate_into_utf8(str, tok-encoding), calls to translate_into_utf8(str, tok-enc) are unchanged (notice: encoding != enc :-)). But it looks like translate_into_utf8(str, tok-enc) is not called if tok-enc is NULL. If tok-encoding is utf-8 and tok-enc is NULL, maybe the input string is not decoded from UTF-8. But it sounds strange, because Python uses Unicode strings. Don't trust me, I would prefer an explanation of Benjamin who knows better than me the parser internals :-) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19519 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

jan matejek added the comment: Yes. We still have a patch for two things: 1. fix setup.py script to look for libraries in correct (lib64) prefixes, and 2. fix values returned from sysconfig, to reflect that python resides in lib64 $prefix/lib is hardcoded in many places. Lib64 is probably not going away anytime soon, so it would be nice if this was solved once and for all ;) The good thing is that with sysconfig, we don't have to do much beyond teaching sysconfig about the right values. To reiterate, our current solution is to introduce sys.lib (and sys.arch, but that is never used anymore) that is either lib or lib64, and use this in place of the string lib wherever appropriate. We find the value for sys.lib through configure magic. -- Added file: http://bugs.python.org/file32529/Python-3.3.0b2-multilib.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue1294959 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

For file based parsing, the codec object created knows what encoding to use; for string-based parsing, tok-enc stores the encoding.

Barry A.

We find the value for sys.lib through configure magic. PEP 421 added sys.implementation, which contains provisions for implementation-specific additions.

STINNER Victor added the comment: Antoine, Martin: So, what do you think? Is it worth to move most common identifiers to a single place to not duplicate them? If identifiers are already cleared at exit, the advantage would be to initialize duplicated identifiers more quickly, and don't initialize duplicated identifiers multiple times (once per copy). If we choose to not share common identifiers, _PyId_xxx identifiers from pythonrun.c must be removed. There are also some identifiers duplicated in the same file which can be moved at the top to remove at least duplicates in a single file, as it was done for other identifiers in issue #19514. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19515 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
