* svn-maint-fixes: Git::SVN::*: avoid premature FileHandle closure git-svn: fix localtime=true on non-glibc environments
2015-02-26Git::SVN::*: avoid premature FileHandle closureLibravatar Kyle J. McKay2-0/+11
Since b19138b (git-svn: Make it incrementally faster by minimizing temp files, v1.6.0), git-svn has been using the Git.pm temp_acquire and temp_release mechanism to avoid unnecessary temp file churn and provide a speed boost. However, that change introduced a call to temp_acquire inside the Git::SVN::Fetcher::close_file function for an 'svn_hash' temp file. Because an SVN::Pool is active at the time this function is called, if the Git::temp_acquire function ends up actually creating a new FileHandle for the temp file (which it will the first time it's called with the name 'svn_hash') that FileHandle will end up in the SVN::Pool and should that pool have SVN::Pool::clear called on it that FileHandle will be closed out from under Git::temp_acquire. Since the only call site to Git::temp_acquire with the name 'svn_hash' is inside the close_file function, if an 'svn_hash' temp file is ever created its FileHandle is guaranteed to be created in the active SVN::Pool. This has not been a problem in the past because the SVN::Pool was not being cleared. However, since dfa72fdb (git-svn: reload RA every log-window-size, v2.2.0) the pool has been getting cleared periodically at which point the FileHandle for the 'svn_hash' temp file gets closed. Any subsequent calls to Git::temp_acquire for 'svn_hash', however, succeed without creating/opening a new temporary file since it still has the now invalid FileHandle in its cache. Callers that then attempt to use that FileHandle fail with an error. We avoid this problem by making sure the 'svn_hash' temp file is created in the same place the 'svn_delta_...' and 'git_blob_...' temp files are (and then temp_release'd) so that it can be safely used inside the close_file function without having its FileHandle end up in an SVN::Pool that gets cleared. Additionally the Git.pm cat_blob function creates a bidirectional pipe FileHandle using the IPC::Open2::open2 function. If that handle is created too late, it also gets caught up in the SVN::Pool and incorrectly closed by the SVN::Pool::clear call. But this only seems to happen with more recent versions of Perl and svn. To avoid this problem we add an explicit call to _open_cat_blob_if_needed before the first call to SVN::Pool->new_default to make sure the open2 handle does not end up in the SVN::Pool.

2015-02-26git-svn: fix localtime=true on non-glibc environmentsLibravatar Ryuichi Kokubo1-1/+2
git svn uses POSIX::strftime('%s', $sec, $min, ...) to make unix epoch time. But lowercase %s formatting character is a GNU extention.

2015-02-26git-svn: lazy load some modulesLibravatar Eric Wong4-14/+19
We can delay loading some modules until we need them for uncommon code paths. For example, persistent memoization is not often needed, so we can avoid loading the modules for it until we encounter svn::mergeinfo during fetch. This gives a tiny reduction in syscalls (from 15641 to 15305) when running "git svn info" and counting via "strace -fc". Further, more invasive work will be needed to noticeably improve performance.

2014-12-09git-svn: support for git-svn propsetLibravatar Alfred Perlstein1-0/+38
This change allows git-svn to support setting subversion properties. It is useful for manually setting properties when committing to a subversion repo that *requires* properties to be set without requiring moving your changeset to separate subversion checkout in order to set props. This change is initially from David Fraser, appearing at: http://mid.gmane.org/1927112650.1281253084529659.JavaMail.root@klofta.sjsoft.com> They are now forward-ported to most recent git along with fixes to deal with files in subdirectories. Style and functional changes from Eric Wong have been taken in their entirety from: http://mid.gmane.org/20141201094911.GA13931@dcvr.yhbt.net There is a nit to point out: the code does not support adding props unless there are also content changes to the files as well.

2014-10-27git-svn: disable _rev_list memoizationLibravatar Eric Wong1-10/+0
This memoization appears unneeded as the check_cherry_pick2 cache is in front of it does enough. With this change applied, importing from local svn+ssh and http copies of the R repo[1] takes only 2:00 (2 hours) on my system and the git-svn process never uses more than 60MB RSS on my x86-64 GNU/Linux system[2]. This 60M measurement is only for the git-svn Perl process itself and does not include memory used by git subprocesses accessing large packs (subprocess memory usage _is_ measured by my time(1) tool). Before this change, an import took longer (2:20) on svn+ssh:// but git-svn used around 240MB during the imports. Worse yet, git-svn ballooned to over 400M when writing out the cache to the filesystem. I also tried removing memoization for `has_no_changes', too, but a local copy of the R repository(*) was not close to finishing within 10 hours on my system.

2014-10-24git-svn: reload RA every log-window-sizeLibravatar Eric Wong1-8/+13
Despite attempting to use local memory pools everywhere we can, (including our call to SVN::Ra::do_update and all subsequent reporter calls), there does not appear to be a way to force the Git::SVN::Fetcher callbacks to use a pool other than the per-SVN::Ra pool. Git::SVN::Fetcher ends up using the main RA pool which grows monotonically in size for the lifetime of the RA object. Thus the only way to free that memory appears to be to destroy and recreate the RA connection for at every --log-window-size interval. This reduces memory usage over the course of fetching 10K revisions using a test repository created with the script at the end of this commit message. As reported by time(1) on my x86-64 system: before: 54024k after: 28680k Unfortunately, there remains some yet-to-be-tracked-down slow memory growth which would be evident as the `nr' parameter increases in the repository generation script: -----------------------------8<------------------------------ set -e tmp=$(mktemp -d svntestrepo-XXXXXXXX) svnadmin create "$tmp" repo=file://"$(cd $tmp && pwd)" svn co "$repo" "$tmp/wd" cd "$tmp/wd" if ! test -f a then > a svn add a svn commit -m 'A' fi nr=10000 while test $nr -gt 0 do echo $nr > a svn commit -q -m A nr=$((nr - 1)) done echo "repository created in $repo" -----------------------------8<------------------------------ Signed-off-by: Eric Wong <normalperson@yhbt.net>

2014-10-24git-svn: only look at the new parts of svn:mergeinfoLibravatar Jakob Stoklund Olesen1-12/+72
In a Subversion repository where many feature branches are merged into a trunk, the svn:mergeinfo property can grow very large. This severely slows down git-svn's make_log_entry() because it is checking all mergeinfo entries every time the property changes. In most cases, the additions to svn:mergeinfo since the last commit are pretty small, and there is nothing to gain by checking merges that were already checked for the last commit in the branch. Add a mergeinfo_changes() function which computes the set of interesting changes to svn:mergeinfo since the last commit. Filter out merged branches whose ranges haven't changed, and remove a common prefix of ranges from other merged branches. This speeds up "git svn fetch" by several orders of magnitude on a large repository where thousands of feature branches have been merged.

2014-06-06Merge branch 'mm/pager-less-sans-S'Libravatar Junio C Hamano1-1/+1
Since the very beginning of Git, we gave the LESS environment a default value "FRSX" when we spawn "less" as the pager. "S" (chop long lines instead of wrapping) has been removed from this default set of options, because it is more or less a personal taste thing, as opposed to others that have good justifications (i.e. "R" is very much justified because many kinds of output we produce are colored and "FX" is justified because output we produce is often shorter than a page). Existing users who prefer not to see line-wrapped output may want to set $ git config core.pager "less -S" to restore the traditional behaviour. It is expected that people find output from the most subcommands easier to read with the new default, except for "blame" which tends to produce really long lines. To override the new default only for "git blame", you can do this: $ git config pager.blame "less -S" * mm/pager-less-sans-S: pager: remove 'S' from $LESS by default
2014-05-07pager: remove 'S' from $LESS by defaultLibravatar Matthieu Moy1-1/+1
By default, Git used to set $LESS to -FRSX if $LESS was not set by the user. The FRX flags actually make sense for Git (F and X because sometimes the output Git pipes to less is short, and R because Git pipes colored output). The S flag (chop long lines), on the other hand, is not related to Git and is a matter of user preference. Git should not decide for the user to change LESS's default. More specifically, the S flag harms users who review untrusted code within a pager, since a patch looking like: -old code; +new good code; [... lots of tabs ...] malicious code; would appear identical to: -old code; +new good code; Users who prefer the old behavior can still set the $LESS environment variable to -FRSX explicitly, or set core.pager to 'less -S'. The documentation in config.txt is made a bit longer to keep both an example setting the 'S' flag (needed to recover the old behavior) and an example showing how to unset a flag set by Git.

2014-01-13Merge branch 'jn/pager-lv-default-env'Libravatar Junio C Hamano1-0/+1
Just like we give a reasonable default for "less" via the LESS environment variable, specify a reasonable default for "lv" via the "LV" environment variable when spawning the pager. * jn/pager-lv-default-env: pager: set LV=-c alongside LESS=FRSX
2014-01-07pager: set LV=-c alongside LESS=FRSXLibravatar Jonathan Nieder1-0/+1
On systems with lv configured as the preferred pager (i.e., DEFAULT_PAGER=lv at build time, or PAGER=lv exported in the environment) git commands that use color show control codes instead of color in the pager: $ git diff ^[[1mdiff --git a/.mailfilter b/.mailfilter^[[m ^[[1mindex aa4f0b2..17e113e 100644^[[m ^[[1m--- a/.mailfilter^[[m ^[[1m+++ b/.mailfilter^[[m ^[[36m@@ -1,11 +1,58 @@^[[m "less" avoids this problem because git uses the LESS environment variable to pass the -R option ('output ANSI color escapes in raw form') by default. Use the LV environment variable to pass 'lv' the -c option ('allow ANSI escape sequences for text decoration / color') to fix it for lv, too. Noticed when the default value for color.ui flipped to 'auto' in v1.8.4-rc0~36^2~1 (2013-06-10).

2013-12-27git-svn: workaround for a bug in svn serf backendLibravatar Roman Kagan1-2/+8
Subversion serf backend in versions 1.8.5 and below has a bug(*) that the function creating the descriptor of a file change -- add_file() -- doesn't make a copy of its third argument when storing it on the returned descriptor. As a result, by the time this field is used (in transactions of file copying or renaming) it may well be released, and the memory reused. One of its possible manifestations is the svn assertion triggering on an invalid path, with a message svn_fspath__skip_ancestor: Assertion `svn_fspath__is_canonical(child_fspath)' failed. This patch works around this bug, by storing the value to be passed as the third argument to add_file() in a local variable with the same scope as the file change descriptor, making sure their lifetime is the same. * [ew: fixed in Subversion r1553376 as noted by Jonathan Nieder] Cc: Benjamin Pabst <benjamin.pabst85@gmail.com> Signed-off-by: Eric Wong <normalperson@yhbt.net> Reviewed-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Roman Kagan <rkagan@mail.ru>
2013-09-06git-svn: fix termination issues for remote svn connectionsLibravatar Uli Heller1-0/+8
git-svn used in combination with serf to talk to svn repository served over HTTPS dumps core on termination. This is caused by a bug in serf, and the most recent serf release 1.3.1 still exhibits the problem; a fix for the bug exists (see https://code.google.com/p/serf/source/detail?r=2146). Until the bug is fixed, work around the issue within the git perl module Ra.pm by freeing the private copy of the remote access object on termination, which seems to be sufficient to prevent the error from happening. Note: Since subversion-1.8.0 and later do require serf-1.2.1 or later, this issue typically shows up when upgrading to a recent version of subversion.

2013-01-19git-svn: do not escape certain characters in pathsLibravatar Peter Wu1-1/+2
Subversion 1.7 and newer implement HTTPv2, an extension that should make HTTP more efficient. Servers with support for this protocol will make the subversion client library take an alternative code path that checks (with assertions) whether the URL is "canonical" or not. This patch fixes an issue I encountered while trying to `git svn dcommit` a rename action for a file containing a single quote character ("User's Manual" to "UserMan.tex"). It does not happen for older subversion 1.6 servers nor non-HTTP(S) protocols such as the native svn protocol, only on an Apache server shipping SVN 1.7. Trying to `git svn dcommit` under the aforementioned conditions yields the following error which aborts the commit process: Committing to http://example.com/svn ... perl: subversion/libsvn_subr/dirent_uri.c:1520: uri_skip_ancestor: Assertion `svn_uri_is_canonical(child_uri, ((void *)0))' failed. error: git-svn died of signal 6 An analysis of the subversion source for the cause: - The assertion originates from uri_skip_ancestor which calls svn_uri_is_canonical, which fails when the URL contains percent-encoded values that do not necessarily have to be encoded (not "canonical" enough). This is done by a table lookup in libsvn_subr/path.c. Putting some debugging prints revealed that the character ' is indeed encoded to %27 which is not considered canonical. - url_skip_ancestor is called by svn_ra_neon__get_baseline_info with the root repository URL and path as parameters; - which is called by copy_resource (libsvn_ra_neon/commit.c) for a copy action (or in my case, renaming which is actually copy + delete old); - which is called by commit_add_dir; - which is assigned as a structure method "add_file" in svn_ra_neon__get_commit_editor. In the whole path, the path argument is not modified. Through some more uninteresting wrapper functions, the Perl bindings gives you access to the add_file method which will pass the path argument without modifications to svn. git-svn calls the "R"(ename) subroutine in Git::SVN::Editor which contains: 326 my $fbat = $self->add_file($self->repo_path($m->{file_b}), $pbat, 327 $self->url_path($m->{file_a}), $self->{r}); "repo_path" basically returns the path as-is, unless the "svn.pathnameencoding" configuration property is set. "url_path" tries to escape some special characters, but does not take all special characters into account, thereby causing the path to contain some escaped characters which do not have to be escaped. The list of characters not to be escaped are taken from the subversion/libsvn_subr/path.c file to fully account for all characters. Tested with a filename containing all characters in the range 0x20 to 0x78 (inclusive). Signed-off-by: Peter Wu <lekensteyn@gmail.com> Signed-off-by: Eric Wong <normalperson@yhbt.net>
2013-01-17git svn: do not overescape URLs (fallback case)Libravatar Jonathan Nieder1-1/+1
Subversion's canonical URLs are intended to make URL comparison easy and therefore have strict rules about what characters are special enough to urlencode and what characters should be left alone. When in the fallback codepath because unable to use libsvn's own canonicalization function for some reason, escape special characters in URIs according to the svn_uri__char_validity[] table in subversion/libsvn_subr/path.c (r935829). The libsvn versions that trigger this code path are not likely to be strict enough to care, but it's nicer to be consistent. Noticed by using SVN 1.6.17 perl bindings, which do not provide SVN::_Core::svn_uri_canonicalize (triggering the fallback code), with libsvn 1.7.5, whose do_switch is fussy enough to care: Committing to file:///home/jrn/src/git/t/trash%20directory.\ t9118-git-svn-funky-branch-names/svnrepo/pr%20ject/branches\ /more%20fun%20plugin%21 ... svn: E235000: In file '[...]/subversion/libsvn_subr/dirent_uri.c' \ line 2291: assertion failed (svn_uri_is_canonical(url, pool)) error: git-svn died of signal 6 not ok - 3 test dcommit to funky branch After this change, the '!' in 'more%20fun%20plugin!' is not urlencoded and t9118 passes again.

2012-12-17git-svn, perl/Git.pm: extend and use Git->prompt method for querying usersLibravatar Sven Strickroth1-9/+7
git-svn reads usernames and other user queries from an interactive terminal. This cause GUIs (w/o STDIN connected) to hang waiting forever for git-svn to complete (http://code.google.com/p/tortoisegit/issues/detail?id=967). This change extends the Git::prompt helper, so that it can also be used for non password queries, and makes use of it instead of using hand-rolled prompt-response code that only works with the interactive terminal.

2012-12-17git-svn, perl/Git.pm: add central method for prompting passwordsLibravatar Sven Strickroth1-19/+1
git-svn reads passwords from an interactive terminal or by using GIT_ASKPASS helper tool. This cause GUIs (w/o STDIN connected) to hang waiting forever for git-svn to complete (http://code.google.com/p/tortoisegit/issues/detail?id=967). Commit 56a853b62c0ae7ebaad0a7a0a704f5ef561eb795 also tried to solve this issue, but was incomplete as described above. Instead of using hand-rolled prompt-response code that only works with the interactive terminal, a reusable prompt() method is introduced in this commit.

2012-10-10git svn: work around SVN 1.7 mishandling of svn:special changesLibravatar Jonathan Nieder1-1/+24
Subversion represents symlinks as ordinary files with content starting with "link " and the svn:special property set to "*". Thus a file can switch between being a symlink and a non-symlink simply by toggling its svn:special property, and new checkouts will automatically write a file of the appropriate type. Likewise, in subversion 1.6 and older, running "svn update" would notice changes in filetype and update the working copy appropriately. Starting in subversion 1.7 (issue 4091), changes to the svn:special property trip an assertion instead: $ svn up svn-tree Updating 'svn-tree': svn: E235000: In file 'subversion/libsvn_wc/update_editor.c' \ line 1583: assertion failed (action == svn_wc_conflict_action_edit \ || action == svn_wc_conflict_action_delete || action == \ svn_wc_conflict_action_replace) Revisions prepared with ordinary svn commands ("svn add" and not "svn propset") don't trip this because they represent these filetype changes using a replace operation, which is approximately equivalent to removal followed by adding a new file and works fine. Follow suit. Noticed using t9100. After this change, git-svn's file-to-symlink changes are sent in a format that modern "svn update" can handle and tests t9100.11-13 pass again.

2012-10-05git-svn: keep leading slash when canonicalizing paths (fallback case)Libravatar Jonathan Nieder1-1/+0
Subversion's svn_dirent_canonicalize() and svn_path_canonicalize() APIs keep a leading slash in the return value if one was present on the argument, which can be useful since it allows relative and absolute paths to be distinguished. When git-svn's canonicalize_path() learned to use these functions if available, its semantics changed in the corresponding way. Some new callers rely on the leading slash --- for example, if the slash is stripped out then _canonicalize_url_ourselves() will transform "proto://host/path/to/resource" to "proto://hostpath/to/resource". Unfortunately the fallback _canonicalize_path_ourselves(), used when the appropriate SVN APIs are not usable, still follows the old semantics, so if that code path is exercised then it breaks. Fix it to follow the new convention. Noticed by forcing the fallback on and running tests. Without this patch, t9101.4 fails: Bad URL passed to RA layer: Unable to open an ra_local session to \ URL: Local URL 'file://homejrnsrcgit-scratch/t/trash%20directory.\ t9101-git-svn-props/svnrepo' contains unsupported hostname at \ /home/jrn/src/git-scratch/perl/blib/lib/Git/SVN.pm line 148 With it, the git-svn tests pass again.

2012-10-05Make git-svn branch patterns match complete URLLibravatar Ammon Riley1-1/+3
When using the {word,[...]} style of configuration for tags and branches, it appears the intent is to only match whole path parts, since the words in the {} pattern are meta-character quoted. When the pattern word appears in the beginning or middle of the url, it's matched completely, since the left side, pattern, and (non-empty) right side are joined together with path separators. However, when the pattern word appears at the end of the URL, the right side is an empty pattern, and the resulting regex matches more than just the specified pattern. For example, if you specify something along the lines of branches = branches/project/{release_1,release_2} and your repository also contains "branches/project/release_1_2", you will also get the release_1_2 branch. By restricting the match regex with anchors, this is avoided. Signed-off-by: Ammon Riley <ammon.riley@gmail.com> Signed-off-by: Eric Wong <normalperson@yhbt.net>
