tests: update regex check for fetch error in test-clonebundles.t On some systems, e.g. Docker container, the actual error may be: error fetching bundle: [Errno 99] Cannot assign requested address Update the regex to handle this case.

hgweb: use separate CSS class for navigation links in footer 2d93d2159e30 changed the styling of the "page_nav" CSS class to use flexbox to separate elements within the <div>. I didn't realize that this class was used outside of the links in the header. So this resulted in incorrectly formatting links in the footer of various pages. Fix that by introducing a new CSS class that preserves the old CSS behavior.

configitems: register 'ui.clonebundleprefers' as example for 'configlist' This exercise the default value handling in 'configlist'.

configitems: register 'patch.fuzz' as first example for 'configint' This exercise the default value handling in 'configint'.

configitems: issue a devel warning when overriding default config If the option is registered, there is already a default value available and passing a new one is at best redundant. So we issue a deprecation warning in this case. (note: there will be case were the default value will not be as simple as what is currently possible. We'll upgrade the configitems code to handle them in time.)

eol: fix 'error' parameter name in the commitctx wrapper Since its introduction in 9dfee83c93c8, the parameter has always been name "error". Yet the eol extension have been using 'haserror' as the argument name, breaking extensions with subclass passing 'error' as a keyword argument.

eol: import 'error' as 'errormod' We need the 'error' name available to fix another bug, so we rename the imported module.

configitems: register 'ui.quiet' as first example We now have a user and this works fine.

configitems: get default values from the central registry when available We do not have any registered config yet, but we are now ready to use them. For now we ignore this feature for config access with "alternates". On the long run, we expect alternates to be handled as "aliases" by the config item themself.

configitems: introduce a central registry for config option We now have the appropriate infrastructure to register config items. Usage will added in the next changeset.

configitems: add a basic class to hold config item information The goal of this class is allow explicit declaration for the available config option. This class will hold the data for one specific config item. To keep it simple we start centralizing the handling of the default config value. In the future we can expect more data to be carried on this class. For example: - documentation, - status (experimental, advanced, normal, deprecated), - aliases, - expected type, - etc...

run-tests: fix -i when "#testcases" is used in .t test The "#testcases" feature introduced by 7340465bd788 has issues with "-i" because "-i" uses "test.name.endswith('.t')" to test if a test is .t or not. test.name could now be something like "test-foo.t (caseA)" so the above endswith test is no longer valid. This patch changes the test to use "self.path" which won't have the issue.

run-tests: update .t reference output after reading the test The .t file is both test input and reference output. They should always match. However we have different code paths to read reference output (Test.__init__ -> Test.readrefout) and test input (TTest._run) so they might be inconsistent if somethings change the file between those two functions. This patch assigns "lines" read by "_run" back to "_refout" if "_refout" is not None (with --debug, see Test.readrefout) so reference output and test input will always match.

run-tests: do not prompt changes (-i) if a race condition is detected The race condition is like: 1. run-tests.py reads test-a.t as reference output, content A 2. run-tests.py runs the test (which could be content B, another race condition fixed by the next patch, but assume it's content A here) 3. something changes test-a.t to content C 4. run-tests.py compares test output (content D) with content A 5. with "-i", run-tests.py prompts diff(A, D), while the file has content C instead of A at this time This patch detects the above case and tell the user to rerun the test if they want to apply test changes.

patch: rewrite reversehunks (issue5337) The old reversehunks code accesses "crecord.uihunk._hunk", which is the raw recordhunk without crecord selection information, therefore "revert -i" cannot revert individual lines, aka. issue5337. The patch rewrites related logic to return the right reverse hunk for revert. Namely, 1. "fromline" and "toline" are correctly swapped [1] 2. crecord.uihunk generates a correct reverse hunk [2] Besides, reversehunks(hunks) will no longer modify its input "hunks", which is more expected. [1]: To explain why "fromline" and "toline" need to be swapped, take the following example: $ cat > a <<EOF > 1 > 2 > 3 > 4 > EOF $ cat > b <<EOF > 2 > 3 > 5 > EOF $ diff a b 1d0 <---- "1" is "fromline" and "0" is "toline" < 1 and they are swapped if diff from the reversed direction 4c3 | < 4 | --- | > 5 | | $ diff b a | 0a1 <---------+ > 1 3c4 <---- also "4c3" gets swapped to "3c4" < 5 --- > 4 [2]: This is a bit tricky. For example, given a file which is empty in working parent but has 3 lines in working copy, and the user selection: select hunk to discard [x] +1 [ ] +2 [x] +3 The user intent is to drop "1" and "3" in working copy but keep "2", so the reverse patch would be something like: -1 2 (2 is a "context line") -3 We cannot just take all selected lines and swap "-" and "+", which will be: -1 -3 That patch won't apply because of "2". So the correct way is to insert "2" as a "context line" by inserting it first then deleting it: -2 +2 Therefore, the correct revert patch is: -1 -2 +2 -3 It could be reordered to look more like a common diff hunk: -1 -2 -3 +2 Note: It's possible to return multiple hunks so there won't be lines like "-2", "+2". But the current implementation is much simpler. For deletions, like the working parent has "1\n2\n3\n" and it was changed to empty in working copy: select hunk to discard [x] -1 [ ] -2 [x] -3 The user intent is to drop the deletion of 1 and 3 (in other words, keep those lines), but still delete "2". The reverse patch is meant to be applied to working copy which is empty. So the patch would be: +1 +3 That is to say, there is no need to special handle the unselected "2" like the above insertion case.

profiling: cope with configwith default value handling changes Changeset 6ff6eb33f353 change 'configwith' behavior so that the default value is run through the conversion function. In parallel a new user of 'configwith' got introduced unaware of this coming behavior change. This broke profiling. We resolve the situation by having the new conversion function cope with a default value already using the right type.

py3: catch StopIteration from next() in generatorset IIUC, letting the StopIteration through would not cause any bugs, but not doing it makes the test-py3-commands.t pass. I have also diligently gone through all uses of next() in our code base. They either: * are not called from a generator * pass a default value to next() * catch StopException * work on infinite iterators * request a fixed number of items that matches the generated number * are about batching in wireproto which I didn't quite follow I'd appreciate if Augie or someone else could take a look at the wireproto batching and convince themselves that the next(batchable) calls there will not raise a StopIteration.

tests: adjust quoting to keep Windows happy with recent $PYTHON change I tried adding quotes to the $PYTHON variable, and also tried converting the path from the current 'c:/Python/python.exe' form to '/c/python/python.exe', but neither worked. I'm not sure why one of these needs '\"' around the variable and the other doesn't.

bundle2: don't use debug message "no-transaction" with transaction

py3: use pycompat.bytestr() in place of str()

py3: use r'' to access values from kwargs where keys are str These are the cases where either args is again passed as keyword argument or 1 or 2 elements are accessed. So it's better to add an r'' to prevent it converting to bytes rather than doing the conversion of args.

py3: convert keys of kwargs in template keywords functions to bytes This patch converts the args argument keys' to bytes wherever necessary as there are some places where either args is not used or using r'' is better or args is again passed as keyword arguments.

py3: make sure the commands name are bytes in test-devel-warnings.t

py3: replace str with bytes in isinstance() We were using str because on Python 2, str were bytes but now we have to use bytes. Otherwise the if conditions fails and we have weird results from commands on Python 3.

py3: catch binascii.Error raised from binascii.unhexlify Before Python 3, binsacii.unhexlify used to raise TypeError, now it raises binascii.Error.

shelve: allow unlimited shelved changes per name Previously, there is a 100 changes limit per name (bookmark or named branch). And the user will get "too many shelved changes named %s" when they are trying to shelve the 101th change. I hit that error message today. This limit was introduced by the shelve extension since the beginning. The function generating the names was called "gennames", under "getshelvename". There is another "gennames" under "backupfilename": def backupfilename(self): def gennames(base): yield base base, ext = base.rsplit('.', 1) for i in itertools.count(1): yield '%s-%d.%s' % (base, i, ext) "itertools.count" is an endless counter. Since the other "gennames" generates unlimited number of names, and the changeset introducing the limit (49d4919d21) does not say why the limit is useful. It seems safe to just remove the limit. The format "%02d" was kept intentionally so existing shelved changes won't break.

config: use the new '_unset' value for 'configsuboptions' This should let configsuboptions delegate all special processing of the default config value to the main 'config' method.

config: use the 'config' method in 'configsuboptions' There was unnecessary code duplication. It was getting in the way of the unification of the default value logic.

config: use the new '_unset' value for 'configpath' This should let 'configpath' delegate all special processing of the default config value to the main 'config' method.

config: use the new '_unset' value for 'configdate' This should let 'configdate' delegate all special processing of the default config value to the main 'config' method. The default value for date (None) is still enforced in this method if no other default were passed.
